Abstract
The invention discloses a pre-pressing device for a pipe joint. The pre-pressing device is connected at one end of a connected part of a to-be-connected pipe and the pipe joint and comprises a casing, wherein the to-be-connected pipe is sleeved with the casing; an inserting connection part is also arranged at one end, close to the pipe joint, of the casing; a plurality of pre-pressing cavities are formed in the circumferential direction of the casing, the inside of each pre-pressing cavity is sequentially connected with an adjusting structure and a pressure spring from outside to inside, and a compression ring is also arranged between each pre-pressing cavity and the to-be-connected pipe. The independent pre-pressing device is added at one end, close to the to-be-connected pipe, of the pipe joint, the pre-pressing force on the to-be-connected pipe is realized, when suddenly increased or suddenly decreased pipe pressure is applied to the pipe, the pipe pressure can be relieved by the aid of the pressure springs and the compression rings which are connected onto the pipe, that is, the pressure springs and the compression rings play roles in absorbing the pipe pressure and sufficiently buffering the pipe pressure, the bursting probability of the pipe is decreased, the safety performance of the pipe is improved, and hydraulic or pneumatic resources are effectively saved.
Description
Technical field
The present invention relates to pipe joint technical field, particularly relate to a kind of pipe joint precompression device.
Background technique
Pipe joint, in the using process of daily pipeline, very important and common, crucial effect is played to the connection of various pipeline, is particularly convenient to the installation of pipeline, collection and transport, and saves the user cost of pipeline, pipe that need not be single, the pipe of waste and old or local damage, can through processing the utilization carried out again, energy saving.
In the connection procedure of pipeline, in the connection procedure of especially high-pressure rubber pipe, require higher to the sealability of pipeline, because high-pressure rubber pipe is multiplex is mine hydraulic support, oil field development, engineering construction, lifting is transported, metallurgical forging and stamping, mining equiment, boats and ships, injection machine, farm machinery, various lathe and each industrial department mechanization, in automatic liquid pressing system, conveying has the petroleum base of certain pressure and temperature (as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricant oil) and water fluid (as emulsified liquid, oil-water emulsion, water) etc. with the pipeline of liquid transmission.And in the using process of high-pressure rubber pipe, the unexpected pressurization due to liquid in pipe can cause the danger of explosion to high-pressure rubber pipe, the position when there is explosion mostly is the pipe joint position that pipeline connects.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of pipe joint precompression device, when its object is to reduce high-pressure rubber pipe in use due to local pressurization suddenly or decompression, cause the probability that high-pressure rubber pipe bursts, improve Safety performance when high-pressure rubber pipe uses and sealability, effectively save the resource such as hydraulic pressure or air pressure.
The technical solution adopted in the present invention is: a kind of pipe joint precompression device, be connected to wherein one end of the connection part of pipeline to be connected and pipe joint, precompression device comprises the housing be enclosed within outside pipeline to be connected, and housing is also provided with cutting graftage part near one end of pipe joint; Housing circumference is also provided with some pretension chambeies, is connected with regulation structure and stage clip respectively in turn from outside to inside, is also provided with compression ring between pretension chamber and pipeline to be connected in each pretension chamber.The present invention adopts increases independent precompression device at pipe joint near one end of band connecting tube, realize the pre-pressing force treating connecting tube, when pipeline suddenly increased or die-off pipe pressure time, by connecting stage clip thereon and compression ring can be eased, namely institute's stage clip and compression ring play absorption tube pressure and abundant separator tube pressure, reduce the probability of pipeline burst, improve its Safety performance, effectively save hydraulic pressure or air pressure resource.
Preferably, several pretension chambeies along the circumferential array of housing, to play uniform buffer function.
Preferably, the quantity in pretension chamber is no less than three, thus plays good pre-pressing effect.
Preferably, housing is also connected with lining away from the inside, one end of pipe joint, improves the wear-resisting property of pre-tightening apparatus.
Preferably, compression ring is rubber ring or compressed sponge circle, to ensure that it has compression ring and has good telescopicing performance.
Preferably, regulation structure is bolt or screw or screwed handle, to regulate the pretightening force of pre-tightening apparatus.
Compared with prior art, the invention has the beneficial effects as follows: the present invention adopts increases independent precompression device at pipe joint near one end of band connecting tube, realize the pre-pressing force treating connecting tube, when pipeline suddenly increased or die-off pipe pressure time, by connecting stage clip thereon and compression ring can be eased, namely institute's stage clip and compression ring play absorption tube pressure and abundant separator tube pressure, reduce the probability of pipeline burst, improve its Safety performance, effectively save hydraulic pressure or air pressure resource.
When present invention reduces high-pressure rubber pipe in use due to local pressurization suddenly or decompression, cause the probability that high-pressure rubber pipe bursts; Improve Safety performance when high-pressure rubber pipe uses and sealability, effectively save the resource such as hydraulic pressure or air pressure.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of pipe joint precompression device.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is further described, and this embodiment, only for explaining the present invention, not forming protection scope of the present invention and limiting.
As shown in Figure 1, a kind of pipe joint precompression device, be connected to wherein one end of the connection part of pipeline 1 to be connected and pipe joint 2, precompression device comprises the housing 3 be enclosed within outside pipeline 1 to be connected, and housing 3 is also provided with cutting graftage part 31 near one end of pipe joint 2; Housing 3 circumference is also provided with some pretension chambeies 32, is connected with regulation structure 4 and stage clip 5 from outside to inside respectively in turn, is also provided with compression ring 6 between pretension chamber 32 and pipeline to be connected 1 in each pretension chamber 32.The present invention adopts increases independent precompression device at pipe joint 2 near one end of band connecting tube 1, realize the pre-pressing force treating connecting tube, when pipeline suddenly increased or die-off pipe pressure time, by connecting stage clip 5 thereon and compression ring 6 can be eased, namely institute's stage clip 5 and compression ring 6 play absorption tube pressure and abundant separator tube pressure, reduce the probability of pipeline burst, improve its Safety performance, effectively save hydraulic pressure or air pressure resource.
