Description
Technical field
The utility model belongs to combustion gas voltage adjusting device technical field, more particularly to a kind of gas pressure regulator, governor.
Background technology
In gas transmission and distribution system, gas pressure regulator, governor is the Gas Regulator as pressure regulation, voltage stabilizing, and its effect is automatic
Regulating gas outlet pressure, stabilize it in a certain pressure limit, to meet the requirement of user.In use,
Small-bore pressure regulator offsets the out-of-balance force that inlet pressure change is brought using lever construction and balance diaphragm more.But balance film
The bearing capacity of piece is smaller, is typically used in below 0.4MPa environment.With back yard industry user in recent years when in use
The raising of inlet pressure so that some lever pressure regulator use conditions with balance diaphragm are restricted.
Utility model content
Technical problem to be solved in the utility model, which is just to provide one kind, can bear higher inlet pressure, and can offset
The gas pressure regulator, governor of out-of-balance force caused by inlet pressure.
In order to solve the above technical problems, the technical solution adopted in the utility model is：Including with air inlet and gas outlet
Valve body, be provided with valve port in valve body, valve body and regulation cavity and cut off cavity and be connected, adjusting film is provided with adjusting cavity body
Piece, regulation diaphragm will adjust cavity and be divided into regulation epicoele and regulation cavity of resorption, and regulation epicoele is provided with regulation spring, adjusts cavity of resorption
Be provided with the pull bar being connected with lever, lever is connected with the valve rod with flap, and flap matches with valve port, gas outlet with
Regulation cavity of resorption is connected, and balanced plug is provided with described valve rod, and the balance set to match with balanced plug is provided with valve body, is put down
Heng Gai, sealing ring is provided between balanced plug and balance set, air cavity, valve rod center are formed between balanced plug, balance set, balance lid
It is provided with the air flue being connected with air cavity.
A kind of gas pressure regulator, governor provided by the utility model reaches valve port in use, gas enters valve body by air inlet,
It is acting upwardly on flap, while gas reaches the gas formed between balanced plug, balance set, balance lid by the air flue at valve rod center
Chamber, it is acting downwardly in balanced plug upper end in balanced plug.Sealed among balanced plug and balance set with sealing ring.Balanced plug and valve port
Size is identical, force direction is on the contrary, out-of-balance force caused by inlet pressure can be completely counterbalanced by.When downstream starts to use gas
When, gas outlet pressure declines, because gas outlet and regulation cavity of resorption are connected, so in the presence of spring is adjusted, and regulation diaphragm band
Dynamic pull bar, lever move right, and lever drives valve rod, balanced plug and flap move up opening valve port, and pressure regulator starts downwards
Trip supply.When gas consumption increase, gas outlet pressure continues to decline, it will drives flap to continue to move up, valve port opening increases
Greatly, so as to meeting the stabilization of gas outlet pressure.The then counter motion when downstream dosage reduces.The flap when downstream gas consumption is zero
Closed completely with valve port, now air inlet gas will not flow into outlet port, and pressure regulator is closed.The utility model
A kind of gas pressure regulator, governor provided, the piston apparatus formed using balance set, balance lid and balanced plug are original flat to replace
Weighed diaphragm, substantially increases the inlet pressure scope of pressure regulator, and piston apparatus is hardly damaged, and service life length, need to only be determined
Phase changes sealing ring.
Brief description of the drawings
Fig. 1 is a kind of structural representation of gas pressure regulator, governor of the utility model；
Fig. 2 is the mplifying structure schematic diagram at A in Fig. 1.
Embodiment
The structure and operation principle of a kind of gas pressure regulator, governor of the utility model are done further specifically below in conjunction with the accompanying drawings
It is bright.
As shown in figure 1, a kind of gas pressure regulator, governor of the utility model includes valve body 1, valve body 1 carries air inlet 2 and gas outlet
3, valve port 4 is provided with valve body 2, valve body 2 is connected with regulation cavity 5 and cut-out cavity 6, and regulation is provided with regulation cavity 5
Diaphragm 7, regulation diaphragm 7 will adjust cavity 5 and be divided into regulation epicoele 51 and regulation cavity of resorption 52, and regulation epicoele 51 is provided with regulation bullet
Spring 8, regulation cavity of resorption 52 are provided with the pull bar 10 being connected with lever 9, and lever 9 is connected with the valve rod 12 with flap 11, valve
Valve 11 matches with valve port 4, and gas outlet 3 is connected with regulation cavity of resorption 52.
As shown in Fig. 2 valve rod 12 carries flap 11, flap 11 matches with valve port 4, and balanced plug is provided with valve rod 12
13, the balance set 14 to match with balanced plug 13, balance lid 15 are provided with valve body 1, is set between balanced plug 13 and balance set 14
Sealing ring 16 is equipped with, forms air cavity 17 between balanced plug 13, balance set 14, balance lid 15, valve rod 12 is provided centrally with and air cavity
17 air flues 18 being connected.
A kind of gas pressure regulator, governor provided by the utility model is in use, gas reaches valve port by air inlet 2 into valve body 1
4, it is acting upwardly on flap 11, while gas reaches balanced plug 13, balance set 14, balance by the air flue 18 at the center of valve rod 12 and covered
The air cavity 17 formed between 15, it is acting downwardly in the upper end of balanced plug 13 in balanced plug 13.Among balanced plug 13 and balance set 14
Sealed with sealing ring 16.Balanced plug 13 is identical with the size of valve port 4, force direction is on the contrary, the pressure of air inlet 2 can be completely counterbalanced by
