Description
Technical field
The utility model belongs to gas transmission and distribution equipment technical field more particularly to a kind of safety-type gas pressure regulator, governor.
Background technique
Gas pressure regulator, governor is the Gas Regulator being specially adapted in gas transmission and distribution system as pressure regulation, pressure stabilizing, extensively
Applied in gas transmission and distribution engineering.It is automatic adjustment gas outlet pressure that it, which is acted on, stablizes it in a certain pressure limit, comes
Meet user's required pressure value, meets requirement.Currently used gas pressure regulator, governor, structure have air inlet, outlet
Mouthful valve body is provided with valve port in valve body, and body base is provided with bottom cover, and body top is provided with adjusting cavity, setting in adjusting cavity
There is adjusting diaphragm, adjusting film piece top is provided with pallet, adjustment spring, adjusting nut, and adjusting diaphragm lower part is provided with and pallet
The valve rod being connected, valve rod bottom end are provided with the work valve to match with valve port.In use, according to setting gas flow, by twisting
Dynamic adjusting nut sets the elastic force of adjustment spring, and making valve port, there are certain intervals between valve of living.Pressure regulator is normal
When work, combustion gas enters valve body by air inlet, by the way that there are flowed out behind gap by gas outlet between valve port and valve living.Outlet at this time
The power that mouth pressure acts on the power of adjusting diaphragm bottom surface and adjustment spring acts on adjusting diaphragm top surface reaches balance, and valve rod is quiet
Only, there are gaps between valve port and valve living, are in normally open state.When gas outlet pressure rise, gas outlet pressure is acted on
When the power of adjusting diaphragm bottom surface acts on the power for adjusting diaphragm top surface greater than adjustment spring, adjusts diaphragm and pallet is driven to move up
Compression adjustment spring, pallet move up band ovable valve stem and move up, and valve rod drives valve living to move up, between valve and valve port living
Gap reduces, and is reduced by the gas flow in gap between valve port and valve living, uses outlet pressure and reduces recovery normal value, thus
Keep normal gas supply.When gas outlet pressure reduction, gas outlet pressure acts on the power for adjusting diaphragm bottom surface less than adjustment spring work
When used in the power for adjusting diaphragm top surface, adjustment spring stretching, extension pushes adjusting diaphragm that pallet is driven to move down, and pallet moves down
Band ovable valve stem moves down, and valve rod drives valve living to move down, and the gap between valve and valve port living increases, by valve port and valve living it
Between the gas flow in gap increase, use outlet pressure increase and restore normal value, to keep normal gas supply.This gas pressure regulating
Device adjusts diaphragm and rupture generation gas leakage easily occurs, cause security risk after working long hours.
Utility model content
Problem to be solved in the utility model is just to provide one kind and is less prone to gas leakage, highly-safe safety-type combustion gas
Pressure regulator.
To solve the above problems, the technical solution adopted in the utility model are as follows: including having air inlet, gas outlet valve body,
Valve port is provided in valve body, body base is provided with bottom cover, and body top is provided with adjusting cavity, is provided with adjusting film in adjusting cavity
Piece, adjusting film piece top are provided with pallet, adjustment spring, adjusting nut, adjust diaphragm lower part and are provided with and are connected with pallet

The blowout disk matched.
Its additional technical feature are as follows: be provided with balance diaphragm between the valve body and adjusting cavity；
Interior signal pipe is provided between the valve body and adjusting cavity；
The bottom of the valve living is provided with guide rod, and the guide sleeve to match with guide rod is provided at the top of bottom cover.
A kind of safety-type gas pressure regulator, governor provided by the utility model adjusts the upper surface of diaphragm and is provided with and adjusts diaphragm
The blowout disk to match.Blowout disk is identical as diaphragm is adjusted, and adjusts diaphragm equal to bilayer is set.When gas pressure regulator, governor exists
After working long hours, diaphragm is adjusted when rupturing, and blowout disk plays the role of identical with adjusting diaphragm, avoids the occurrence of leakage
Gas, it is ensured that combustion gas does not leak, and guarantees the safety of gas pressure regulator, governor.Balance diaphragm is provided between valve body and adjusting cavity, it can be effective
Influence of the variation of equalization inlet pressure to gas outlet pressure.It is provided with interior signal pipe between valve body and adjusting cavity, can guarantee out
Outlet pressure is fed back correct, avoids the problem that external signal pipe Mulit-point Connection is also easy to produce gas leakage.The bottom setting of valve living
There is guide rod, the guide sleeve to match with guide rod is provided at the top of bottom cover.When moving up and down, guide rod is being oriented to valve living
It is moved up and down in set, so that valve living is not deviated valve port, it is ensured that the stability and negotiability of gas pressure regulator, governor.
