Description
Technical field：
The present invention relates to gas-fired equipment detection technique field more particularly to a kind of durabilities for gas pressure regulator, governor diaphragm
Detection device.
Background technology：
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 city gas cause advance, quality, property of the people to gas-fired equipment
More stringent requirements are proposed for energy and safety, to ensure the safety and reliability of city gas supply, does not only turn off and sends out
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, 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 the vulnerable part that pressure regulation epithelium is gas pressure regulator, governor, need replacing.Existing diaphragm robustness detection device is for example special
Profit number is a kind of gas pressure regulator, governor epithelium testing machine disclosed in CN202442864U, include for fix the epithelium pallet of diaphragm with
And the driving mechanism that driving diaphragm and epithelium pallet pump simultaneously, by simulating fortune of the 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, since diaphragm is fixed by epithelium pallet and is moved up and down simultaneously, epithelium pallet has support force, testing result to diaphragm
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 measured is significantly greater than actual life.
Invention content：
The purpose of the present invention is in view of the drawbacks of the prior art, provide it is a kind of it is simple in structure, easy to operate, versatile,
Measure the durability detection device for being accurately used for gas pressure regulator, governor diaphragm.
The present invention is achieved through the following technical solutions：A kind of durability for gas pressure regulator, governor diaphragm detects dress

Can effectively diaphragm be compressed by clamping disk in order to facilitate diaphragm, and prevent plenum chamber gas leakage, outside the plenum chamber
End is detachably connected with ring flange, and diaphragm clamps disk and can close diaphragm lid on ring flange.
Then, it is envisaged that the driving problems of diaphragm.It is typically all to be actually used according to diaphragm in the prior art
Mode of vibration in the process carries out analog-driven.However, its driving mechanism is more single, it is generally only capable of a kind of corresponding size
Diaphragm is detected, and due to its structural limitations, needs to use the electronic component of sensor etc to carry out metering sense
It answers, cost is higher.
Therefore, how it to be directed to various sizes of diaphragm, is matched with positioning component, makes its reciprocating motion, and can
It is another technical problem to be solved by the invention to reduce production cost.
The present invention devises special vibration component, and the vibration component is fixed on the one of the remotely located component in rack top
