Description
Technical field
The utility model belongs to combustion gas voltage adjusting device technical field more particularly to a kind of pressure regulation, cutting integrated gas
Pressure regulator.
Background technique
Gas pressure regulator, governor is the Gas Regulator being specially adapted in gas transmission and distribution system as pressure regulation, pressure stabilizing, is made
With being automatic adjustment gas outlet pressure, stablize it in a certain pressure limit, to meet the requirement of user.Pressure regulation,
Cutting integrated gas pressure regulator includes having air inlet, gas outlet, the valve body for cutting off chamber and adjusting cavity, is provided with valve in valve body
Mouthful, diaphragm is provided in adjusting cavity, adjusting cavity is divided by diaphragm to be adjusted epicoele and adjust cavity of resorption, is adjusted epicoele and is provided with adjusting
Spring adjusts cavity of resorption and is provided with balance diaphragm, and the valve rod that top is connected with diaphragm passes through balance diaphragm and stem guiding set, valve
Bar bottom is provided with the flap to match with valve port, and gas outlet is connected with adjusting cavity of resorption by signal pipe.In use, gas by
Air inlet enters valve body, flows to gas outlet by valve port, gas outlet pressure rise at this time, by under signal pipe feedback to adjusting
Chamber makes diaphragm overcome the power of adjustment spring to move up with ovable valve stem and flap, reduces valve port at a distance from flap.Such as gas consumption
It is that zero valve port will continue to reduce at a distance from flap until closing.If instead gas consumption increases, then gas outlet pressure declines,
Diaphragm will drive valve rod under the action of adjustment spring and flap moves down, and increase valve port at a distance from flap, to meet use
Family uses the requirement of flow and pressure.Since there are gaps between valve rod and stem guiding set, the gas of valve body is entered by air inlet
Know from experience by valve rod and stem guiding set between gap reach balance diaphragm below, inlet pressure to balance diaphragm generate to
On closing forces, air exercise the distance between valve opening mouth and flap generate hinder, influence the effective discharge of gas pressure regulator, governor.
Utility model content
Technical problem to be solved in the utility model be just to provide it is a kind of it is compact-sized, negotiability is big, the precision of voltage regulation
High pressure regulation, cutting integrated gas pressure regulator.
In order to solve the above technical problems, the technical solution adopted in the utility model is：Including with air inlet, gas outlet,
The valve body of chamber and adjusting cavity is cut off, valve port is provided in valve body, diaphragm is provided in adjusting cavity, adjusting cavity is divided into tune by diaphragm
It saves epicoele and adjusts cavity of resorption, adjust epicoele and be provided with adjustment spring, adjust cavity of resorption and be provided with balance diaphragm, top is connected with diaphragm
The valve rod connect passes through balance diaphragm and stem guiding set, stem bottom are provided with the flap to match with valve port, gas outlet and tune
Section cavity of resorption is connected by signal pipe, and the bottom of the stem guiding set is provided with bell mouth shape speedup cover.
Its additional technical feature is：The speedup cover is flexibly connected with stem guiding set.
Pressure regulation provided by the utility model, cutting integrated gas pressure regulator, the bottom of stem guiding set are provided with loudspeaker
Mouth shape speedup cover, speedup cover is close to valve port.In use, gas enters valve body by air inlet, gas outlet is flowed to by valve port.Together
When, balance diaphragm cavity of resorption can be reached by the gap between valve rod and stem guiding set by the gas that air inlet enters valve body, into
Outlet pressure is acting upwardly on balance film on piece, is acting downwardly on flap, and inlet pressure generates upwards balance diaphragm
Closing forces.When pressure regulator is when big flow is run, gas flow rate is fast at valve port, position and special horn mouth due to speedup cover
Shape, speedup cover inner cavity can form negative pressure, and the pressure of balance diaphragm cavity of resorption is reduced by way of taking negative pressure, reduce air inlet pressure
Power acts on the closing forces of balance film on piece, helps to open the distance between valve port and flap, increases effective stream of pressure regulator
Amount.Speedup cover is flexibly connected with stem guiding set, facilitates installation.
Detailed description of the invention
Fig. 1 is the utility model pressure regulation, the structural schematic diagram for cutting off integrated gas pressure regulator；
Fig. 2 is the enlarged structure schematic diagram in Fig. 1 at A.
Specific embodiment
With reference to the accompanying drawing to the utility model pressure regulation, cut off integrated gas pressure regulator structure and working principle do into
One step is described in detail.
As shown in Figure 1, the utility model pressure regulation, cutting integrated gas pressure regulator include valve body 1, valve body 1 has air inlet
Mouthfuls 2, gas outlet 3 and adjusting cavity 4 are provided with valve port 5 in valve body 1, diaphragm 6 are provided in adjusting cavity 4, diaphragm 6 divides adjusting cavity 4
It is divided into and adjusts epicoele 41 and adjust cavity of resorption 42, adjust epicoele 41 and be provided with adjustment spring 7, adjust cavity of resorption 42 and be provided with balance diaphragm
8, the valve rod 9 that top is connected with diaphragm 6 passes through balance diaphragm 8 and stem guiding set 10, and 9 bottom of valve rod is provided with and valve port 5
The flap 11 to match, gas outlet 3 and adjusting cavity of resorption 42 are connected by signal pipe 12, and the bottom of stem guiding set 10 is provided with
Bell mouth shape speedup cover 13.
As shown in Fig. 2, valve rod 9 passes through stem guiding set 10,9 bottom of valve rod is provided with the flap 11 to match with valve port 5,
The bottom of stem guiding set 10 is provided with bell mouth shape speedup cover 13, and speedup cover 13 is flexibly connected with stem guiding set 10.
Pressure regulation provided by the utility model, cutting integrated gas pressure regulator are in use, gas enters valve by air inlet 2
Body 1 flows to gas outlet 3 by valve port 5, at this time 3 pressure rise of gas outlet, by the feedback of signal pipe 12 to cavity of resorption 42 is adjusted, makes
Diaphragm 6 overcomes the power of adjustment spring 7 to move up with ovable valve stem 9 and flap 11, reduces valve port 5 at a distance from flap 11.Such as use
Tolerance is that zero valve port 5 will continue to reduce at a distance from flap 11 until closing.If instead gas consumption increases, then gas outlet 3
Pressure decline, diaphragm 6 will drive valve rod 9 under the action of adjustment spring 7 and flap 11 moves down, and increase valve port 5 and flap
11 distance, to meet the requirement that user uses flow and pressure.Valve body 1 is entered by air inlet 2 in gas, is flowed by valve port 5
While to gas outlet 3, by air inlet 2 enter valve body 1 gas can by the gap between valve rod 9 and stem guiding set 10 to
Up to balance 8 cavity of resorption of diaphragm, inlet pressure is acting upwardly on balance diaphragm 8, is acting downwardly on flap 11, inlet pressure
Upward closing forces are generated to balance diaphragm 8.When pressure regulator is when big flow is run, gas flow rate is fast at valve port 5, due to speedup
The position and special bell shape, 13 inner cavity of speedup cover of cover 13 can form negative pressure, and balance is reduced by way of taking negative pressure
The pressure of 8 cavity of resorption of diaphragm reduces the closing forces that 2 pressure of air inlet acts on balance diaphragm 8, helps to open valve port 5 and valve
The distance between valve 11 increases the effective discharge of pressure regulator.Speedup cover 13 is flexibly connected with stem guiding set 10, facilitates installation.
