It plays valve port 41 to become larger or become smaller, to adjust pressure regulator outlet pressure.
It is described in detail below for the structure and principle of the utility model key feature.
1) balance valve core structure
Valve seat 5 and balance rubber film component part 6 constitute balance valve core structure.When 2 pressure of gas pressure regulator, governor air inlet becomes
When change, valve pad 6-1 will receive the effect of the out-of-balance force of import high-pressure gas generation, and 41 gap of valve port is caused to will increase or subtract
It is small, exceed precision of voltage regulation range so as to cause outlet pressure.This patent is provided with balance valve core structure, and pressure pin 6-2 is provided with throttling
Hole 44, import high-pressure gas enters balance diaphragm 6-4 epicoele by throttle orifice 44, to balance suffered by valve pad 6-1
Out-of-balance force improves the pressure regulating performance of pressure regulator, improves the precision of voltage regulation.
2) lever pressure adjusting structure
Lever is constituted by the components that the lever arm I 12 of living hinge is connected with lever arm II 11 and other
Pressure adjusting structure.The inclined central bearing point of lever arm II 11 and lower 7 fixed hinge of chamber lid form the fixed pivot of multiplying lever structure, Gu
Fulcrum is determined close to cam pair.Lever arm II 11 passes through the movement of valve pad 6-1 in cam subband dynamic balancing diaphragm 6, thus control valve
The size of mouth 41.When the pressure oscillation of pressure regulator import and export excessively or too frequently breathe by caused pressure regulator, unstable gas
Entering lower chambers 8 by pressure guiding pipe 40 drives main film 23 to drive the connection member movement that is connected, and causes the wave of pressure regulator outlet pressure
Dynamic, this patent lever pressure adjusting structure reduces the width that 41 gap of valve port increases or reduces by the effect of multiplying lever
Degree, to improve the precision of voltage regulation of pressure regulator；Since there are certain errors for the processing of valve seat 5 and assembly, lead to 5 sealing surface of valve seat
It is unable to get guarantee with the depth of parallelism of valve pad 6-1 sealing surface, when pressure regulator is closed, palette face is bad, needs to add
23 driving force of big main film, can just be such that pressure regulator is closed, to cause closing pressure higher.This patent lever pressure regulation
Structure will act at the power amplification of 23 lower end of main film, improve the closing pressure of pressure regulator by the effect of multiplying lever
Precision.
3) integral type bleeding device
18 groups of adjusting nut of lever arm I 12, the first O-ring seals 24, axle sleeve 21, tossing in spring 19 and release are integrated
Bleeding device.In the case that pressure regulator works normally, since release adjusting nut 18 has certain preload, axis to tossing in spring 19
Set 21 realizes by the first O-ring seals 24 with I 12 taper position of lever arm and seals that means for diverging does not work；When pressure regulator goes out
When mouth hypertonia is more than precision of voltage regulation range, 8 gas push main film 23 of lower chambers is up moved, and upward power is more than
After the pretightning force release setting pressure that tossing in spring 19 generates, axle sleeve 21 is significantly lifted, and the gas of lower chambers 8 passes through axle sleeve
Gap between 21 and lever arm I 12 small volume exhaust (not filling the second O-ring seals 20) outward, restores to 8 gas of lower chambers
To release setup pressure value, bleeding device is automatically closed；Release function is controlled by adjusting the presence or absence of second O-ring seals 20
Whether having of energy does not fill the second O-ring seals 20 if pressure regulator requires have diffusion function, if pressure regulator requires not have
Standby diffusion function, then fill the second O-ring seals 20；It can be by adjusting the setting release pressure value of tossing in spring 19.Therefore, this is special
Sharp integral type bleeding device can be realized small flow release when gaseous-pressure exceeds precision of voltage regulation range once in a while,
It prevents pressure regulator from not cutting off, guarantees that downstream gas supply is normal
4) integral type disconnecting device
Cut off chamber lid 38 under valve pad 25, valve rod 33, disconnecting device, cutting diaphragm 27, cutting adjustment spring 30 and valve body 1 etc.
The integrated disconnecting device of the components group that is connected.When the pressure change of pressure regulator gas outlet 3, if pressure is in the model of restriction
In enclosing, three steel balls 36 block valve rod 33, and cutting compressed spring 26 is shunk, and have between cutting valve pad 25 and valve seat 5 certain
Gap supplied gas flows through；If pressure pushes cutting pressing plate 28 mobile beyond the range limited, by the cutting diaphragm 27 of pressure, three
Steel ball 36 slides into the gap between cutting pressing plate 28 and cut-out axle sleeve 42, and valve rod 33 is threaded off, and 26 diastole of compressed spring is cut off, and compresses
Valve pad 25 is cut off, 5 import of valve seat is sealed up, gas cutting is realized, prevents the generation of downstream security accident.It is subsequent to be revolved by drawing lid 32
It covers and is pulled open in 33 end of valve rod, carry out manual reset, different cut-out pressure values can be set by adjusting adjusting nut 34.
The present embodiment ingehious design balance valve core structure, solves the problems, such as out-of-balance force suffered by valve pad, when inlet and outlet are pressed
When power changes, so that outlet pressure is stablized in specific accuracy rating；It will act at the power of main film lower end by the effect of lever
Amplification, improves the closing pressure precision of pressure regulator；Valve pad is reduced since combustion gas fluctuation in downstream causes by the effect of lever
Mobile range, improve the precision of voltage regulation of pressure regulator；A kind of and pressure regulator integral type bleeding device is provided, in gas pressure
When couple that exceeds precision of voltage regulation range, it can be realized small flow release, prevent pressure regulator from not cutting off, guarantee downstream gas supply
Normally；A kind of and pressure regulator integral type disconnecting device is provided, when gaseous-pressure is more than limit value, can automatically cut off, prevent
Only downstream pressure is excessively high causes safety accident；Perfect in shape and function, integrated level is high, ingenious in design, high reliablity.
It is the preferred embodiment of the utility model above, those of ordinary skill in the art can also carry out respectively on this basis
Kind of transformation improves, and under the premise of not departing from the utility model total design, these transformation or improves this reality all should belong to
Within the scope of novel be claimed.
