Abstract
The invention discloses a pressure reducing valve, and relates to the field of hydraulic equipment. The pressure reducing valve comprises a body, wherein the body comprises a shell, a valve is arranged inside the shell, two ends of the shell are connected with pipelines, a gas inlet and a gas outlet are respectively formed on the pipelines on the two ends, a locking port is formed outside the pipeline which is connected with the gas inlet; a gas leakage alarm is arranged on the shell, when the air leakage reaches a certain concentration, the gas leakage alarm can make a sound, thereby reminding people of closing a liquid gas storage tank and opening a window for ventilation; each pipeline is designed as a spiral curly pipeline, so that the time for the gas to pass through the valve is increased, the resistance is increased, and the gas output of the liquid gas can be adjusted and controlled better; a purification filter screen is arranged on the gas inlet, so that impurities in the liquid gas are filtered out and can not enter into the pressure reducing valve pipeline to block the pipeline, and meanwhile, the gas quality is enhanced.
Description
Technical field
The present invention relates to the hydraulic equipment field, be specifically related to a kind of reduction valve.
Background technique
Reduction valve is the equipment of indispensability while using rock gas or liquid gas, be used for reducing gas pressure intensity, the critical component that gas uniform speed is flowed out, application number is 201180031274.1 to disclose a kind of responsiveness, serviceability and reliability excellence, can access the reduction valve of stable output characteristics, reduction valve possesses shell, this shell has the valve path that links first side port and second side port, again, be provided with in the enclosure valve body, this valve body can and be opened between the open position of valve path and move in the closed position of cut-off valve path, aperture to the valve path is adjusted, again, valve body is pushed to closed position under the effect of secondary pressure, be provided with spring component, to resist this secondary, press valve body to the open position application of force, in addition, be provided with rolling bearing on valve body, utilize this rolling bearing to support movably valve body,
summary of the invention
The object of the present invention is to provide a kind of reduction valve, to solve the above-mentioned multinomial defect caused in prior art.
A kind of reduction valve, comprise body, described body comprises shell, be provided with valve in described shell, described shell two ends are connected with pipeline, on the pipeline of described two ends, are respectively equipped with suction port and air outlet, described suction port institute's connecting leg is provided with fore shaft outside road, described shell is provided with leakage alarm, and described pipeline is made as the spirality crimping pipeline, and described suction port is provided with the purification filter screen.

As shown in Figure 1, a kind of reduction valve, comprise body 1, described body 1 comprises shell 2, be provided with valve 3 in described shell 2, described shell 2 two ends are connected with pipeline 4, be respectively equipped with suction port 5 and air outlet 6 on described two ends pipeline 4, described suction port is provided with fore shaft 7 outside 5 connecting leg roads, described shell 2 is provided with leakage alarm 8, reach finite concentration in air leakage low, can sound, be convenient to remind people to close liquefied gas tank, and the ventilation of windowing, described pipeline is made as the spirality crimping pipeline, increase gas by the time of valve, increase resistance, can better regulate and control the gas output of liquid gas, described suction port 5 is provided with and purifies filter screen 9, filter out the impurity in liquid gas, make it can not enter the reduction valve pipeline, and then blocking pipe, also increased the quality of combustion gas simultaneously.
Wherein, described purification filter screen is provided with 3-5 metafiltration net, and the stack of multiple tracks filter screen can all keep off most impurity at the suction port place, convenient for cleaning and replacing.
It should be noted that described fore shaft 7 is provided with seal ring 10, increased the tightness of reduction valve and liquefied gas tank joint, reduce and avoid leaking gas.
Based on above-mentioned, this structure of relief pressure valve is reasonable, easy to use, described shell is provided with leakage alarm, reach finite concentration in air leakage low, can sound, be convenient to remind people to close liquefied gas tank, and the ventilation of windowing, described pipeline is made as the spirality crimping pipeline, increase gas by the time of valve, increase resistance, can better regulate and control the gas output of liquid gas, described suction port is provided with the purification filter screen, filter out the impurity in liquid gas, make it can not enter the reduction valve pipeline, and then blocking pipe.
As known by the technical knowledge, the present invention can realize by other the embodiment that does not break away from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrate, and is not only.Change within the scope of the present invention all or within being equal to scope of the present invention all is included in the invention.
