The gas pressure regulator, governor component part important as gas-fired equipment, is widely used in people's lives, heating, refrigeration, hair
The every field such as electricity, as China's economy and the continuous of gas cause advance, quality, property of the people to gas-fired equipment
More stringent requirements are proposed for energy and safety, for the safety and reliability for ensureing city gas supply, does not only turn off sending
It accords with the demands of the market, the high quality novel gas pressure regulator with independent intellectual gradually substitutes import, could improve our combustion
Gas device fabrication is horizontal, promotes the competitiveness of enterprise.
It is general in gas pressure regulator, governor in the prior art that all there is diaphragm, due to diaphragm at work need constantly to do it is past
Multiple movement, therefore pressure regulation epithelium is the vulnerable part of gas pressure regulator, governor, is needed replacing.Existing diaphragm robustness detection device is for example special
Benefit number is a kind of gas pressure regulator, governor epithelium testing machine disclosed in CN202442864U, including the epithelium pallet for fixing diaphragm with
And the driving mechanism that driving diaphragm and epithelium pallet pump simultaneously, pass through fortune of the simulation diaphragm in gas pressure regulator, governor
Flowing mode detects its service life.However its structure is complex, cost of manufacture is higher, and diaphragm is mounted on bonnet, and lower valve
The cavity inside of composition is covered, since gas pressure regulator, governor volume is generally all larger, weight is also heavier, and diaphragm is very time-consuming when installing to be taken
Power, and the vibration reciprocating stroke of the structure is non-adjustable, can not targetedly detect；Simultaneously as it does not account for diaphragm institute
The abominable and diversity for locating environment, are simulated only under atmospheric pressure environment, and inaccurate, and detection is more limited to；
In addition, epithelium pallet has support force, testing result to diaphragm since diaphragm is fixed by epithelium pallet and moves up and down simultaneously
It is inaccurate.In conclusion although the gas pressure regulator, governor epithelium testing machine is capable of the service life of roughly measuring diaphragm,
Its measurement result is simultaneously inaccurate, our experiments show that, the diaphragm lifetime data of measurement is significantly greater than actual life.
