The invention relates to a seal leakage alarm device for a corrugated pipe, which comprises a packing gland device, packing, a packing box, a packing box metal base, the corrugated pipe and a lower corrugated pipe. The packing box is arranged in the packing box metal base, the upper end of the corrugated pipe is fixedly connected with the packing box metal base, the lower end of the corrugated pipe is fixedly connected with the lower corrugated pipe, the packing is arranged in the packing box, the packing gland device is hermetically pressed above the packing box, the packing box metal base and the packing, pores for transmitting light are arranged on the packing box metal base, and the packing box is made of transparent materials evenly mixed with indicators capable of sensitively recognizing acid and alkaline fluids. By adding the indicators, the seal leakage alarm device is capable of sensitively discoloring along with change of PH (potential of hydrogen) values, so that leakage can be sensitively reflected. Besides, leakage is reflected timely, rapidly, visually and conspicuously, so that safety of the corrugated pipe is greatly enhanced.
Description
Technical field
The present invention relates to a kind of sylphon seal leakage warning device, being specially a kind of medium that is applicable to is the bellows arrangement of fluids such as liquid or the gas of pH value.
Background technique
The bellows of existing technology generally adds a leak-checking apparatus at bellows after leaking, and is not the device that is integrated with bellows, and it is more generally speaking that bellows leaks, and only depends on leak detector, can't know that bellows leaks the very first time.And the leakage of fluids such as the liquid of the leakage of bellows, especially pH value or gas often can cause great potential safety hazard and extreme consequence.
Summary of the invention
Technical problem to be solved by this invention provides a kind of reasonable in design, can reflect leakage in real time, intuitively showy, safe, change sylphon seal leakage warning device easily.
It is this sylphon seal leakage warning device that the present invention solves the problems of the technologies described above the technological scheme that is adopted; Comprise Gland device, filler, stuffing box, stuffing box metal seat, bellows, following corrugated header; Said stuffing box is arranged in the stuffing box metal seat; The upper end of said bellows is fixedly connected with the stuffing box metal seat, and the lower end of said bellows is fixedly connected with following corrugated header, is provided with filler in the said stuffing box; The top that is pressed in stuffing box, stuffing box metal seat, filler that described Gland device is airtight; Be characterized in: said stuffing box metal seat is provided with the aperture that is used for printing opacity, and said stuffing box is a transparent material, is mixed with the indicator that can discern the pH value fluid sensitively in the material of said stuffing box uniformly.The adding of indicator, variable color that can be responsive, thereby the situation of reaction leakage that can be responsive because of the variation of pH value.In time, fast, reaction directly perceived and showy leaks, and increased the Security of bellows arrangement greatly.Because filler and stuffing box itself have the function of leakproof, so, can not make leak of liquid arrive the outside because of the existence of aperture.
As preferably, evenly be provided with the indicator identical in the filler according to the invention with stuffing box, said filler is a transparent material.Guaranteed the receptance for the soda acid leak of liquid, the very first time reflects the situation of leakage.
As preferably, aperture according to the invention is evenly distributed on the circle of stuffing box metal seat with exposing highly different by stuffing box metal seat circumferential size.Guaranteeing all has aperture from all directions, from all angles, can observe the situation of indicator discoloration.Further guaranteed the timely reaction of leakage situation, more directly perceived and responsive.
As preferably, evenly contain in the Gland device according to the invention with stuffing box in identical indicator, said Gland device is a transparent material.Further strengthened the sensitivity response of whole device, can detect the leakage of All aspects of leaking.
As preferably, stuffing box metal seat according to the invention and bellows welding are fixing.
As preferably, corrugated header down according to the invention is fixed with the bellows welding.
Said indicator is purple reindeer moss, bromthymol blue, phenolphthalein, methyl red or methyl orange.Different liquids uses different indicator, can more responsively react the situation and the degree of leaking rapidly.
The present invention compares with existing technology and has the following advantages and effect: because having used, the present invention has the stuffing box and the associated component of leaking colour change function, and the stuffing box metal seat with printing opacity aperture, when taking place to leak; At first along the bellows inwall, up leak between metal seat through stuffing box and valve rod wall, during through the transparent plastic of stuffing box; Transparent plastic will be because of the variation variable color of pH value, and when the medium that leaks progressively increased, the degree of variable color also progressively strengthened; After arriving the plastic cement filler; The plastic cement filler also begins variable color, like this, just knows that through range estimation the medium in the valve flowing channel has leakage to come out from bellows.The advantage of this structure is to be skillfully constructed, and the stuffing box metal seat in the structure, stuffing box, filler, Gland are made simple, and it is convenient to change, and leakage information comes into plain view.Simultaneously; Transparent plastic cement filler has and stuffing box transparent plastic identical functions; The conventional func of filler is after medium leaks out through bellows from container or pipeline; Play to stop and temporaryly leak heavy dose ofly, and the filler among the present invention is not only realized conventional func, but also play the function of warning.

Label declaration: Gland device 1, stuffing box 2, stuffing box metal seat 3, filler 4, bellows 5, following corrugated header 6, aperture 7.
Embodiment
Below in conjunction with embodiment the present invention is done further detailed description, following examples are to explanation of the present invention and the present invention is not limited to following examples.
Embodiment 1: shown in Fig. 1 to 3, the sylphon seal leakage warning device of present embodiment is made up of Gland device 1, stuffing box 2, stuffing box metal seat 3, filler 4, bellows 5, following corrugated header 6.The lower end of bellows 5 upper ends and stuffing box metal seat 3 welds together, and bellows 5 lower ends weld together with following corrugated header 6, forms the bellows grip assembly.The inboard of stuffing box metal seat 3 is fixed with stuffing box 2, and filler 4 is installed in the stuffing box 2.
Stuffing box metal seat 3 is injection molded into one with the stuffing box 2 that transparent plastic is processed; Stuffing box metal seat 3 exposed parts are by the aperture 7 of many rules; General one the circle in can by stuffing box metal seat 3 circumferential size with expose highly different dividing equally, the assurance aperture 7 is all arranged from all directions, in the present embodiment; On four direction, be provided with, each direction is provided with 2.Stuffing box 2 is a kind of transparent plastics that can discern the pH value fluid sensitively; Be uniformly distributed with the indicator that can discern the pH value fluid sensitively in these plastics, along with the increase of fluid flow, the degree of variable color strengthens; During this plastics variable color, can both see the situation of variable color from all angles.
The filler 4 of transparent plastic cement material is housed in stuffing box 2; This type plastic material have with stuffing box 2 in transparent plastic identical functions is arranged; The conventional func of filler 4 is after medium leaks through bellows 5 from container or pipeline; Play to stop and temporaryly leak heavy dose ofly, and the filler 4 among the present invention is not only realized conventional func, but also play the function of warning.
Gland device 1 of the present invention is consistent with the material of stuffing box 2, and the function that is produced also is the same.Can reach identical effect.
