Description
Technical field
The utility model belongs to combustion gas voltage adjusting device technical field, relates in particular to a kind of gas pressure regulator, governor.
Background technique
Gas pressure regulator, governor is to be specially adapted in gas transmission and distribution system, as the Gas Regulator of pressure regulation, voltage stabilizing, being widely used in gas transmission and distribution engineering.Its effect is automatic regulating gas air outlet pressure, makes it be stabilized in a certain pressure range, meets user's required pressure value, meets usage requirement.Pressure governor comprises the valve body with suction port and air outlet, is provided with valve port, diaphragm in valve body, is provided with spring above diaphragm, is provided with the valve rod with valve seat below diaphragm.During use, diaphragm cavity of resorption gaseous-pressure changes moves up and down telescopic spring band dynamic diaphragm and valve rod, and regulating valve seat and valve port gap are to regulate the end pressure of giving vent to anger.This gas pressure regulator, governor is not suitable for the gas pipeline of little pressure, large flow.
Model utility content
Technical problem to be solved in the utility model is just to provide a kind of gas pressure regulator, governor that is applicable to little pressure, large flow gas pipeline.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the valve body with suction port and air outlet, the valve seat that is provided with valve port in valve body and matches with valve port, above described valve seat, be provided with spring, the bottom surface of valve seat is connected with valve rod, valve rod bottom is connected with regulating the diaphragm in chamber below valve body, diaphragm is divided into epicoele and cavity of resorption by adjusting chamber, suction port, epicoele and cavity of resorption are respectively by the first connecting tube, the second connecting tube, the 3rd connecting tube is connected with restrictor, air outlet is connected with pilot valve by the 4th connecting tube, pilot valve is connected with epicoele by the 5th connecting tube.
Its additional technical feature is: the arranged outside of described spring has location cylinder, is provided with the guide cylinder matching with location cylinder above valve seat.
When gas pressure regulator, governor provided by the utility model is used, combustion gas enters valve body from suction port, combustion gas simultaneously also arrives restrictor from suction port by the first connecting tube, after restrictor, by the 3rd connecting tube, arrive cavity of resorption again, cavity of resorption pressure rises, upwards hold up diaphragm and valve rod, valve seat leaves valve port, combustion gas enters valve body by valve port and is gone out by air outlet, air outlet pressure feeds back to pilot valve by the 4th connecting tube, by pilot valve, by the 5th connecting tube, feed back to epicoele again, by epicoele, by the second connecting tube, feed back to restrictor again, epicoele and cavity of resorption produce pressure balance, combustion gas is passed through.When air outlet pressure strengthens, by the 4th connecting tube, feed back to pilot valve, then by the 5th connecting tube, feed back to epicoele by pilot valve, upper cavity pressure rises, and promotes diaphragm and valve rod downwards, and valve seat, near valve port, reduces by combustion gas, air outlet pressure decreased.When air outlet, pressure reduces, and by the 4th connecting tube, feeds back to pilot valve, then by the 5th connecting tube, feeds back to epicoele by pilot valve, and upper cavity pressure reduces, and cavity of resorption upwards holds up diaphragm and valve rod, and valve seat, away from valve port, increases by combustion gas, and air outlet pressure raises.So adjust gas port pressure, reach and control suction port and the pressure balanced object in air outlet.And the arranged outside of spring has location cylinder, above valve seat, be provided with the guide cylinder matching with location cylinder.When valve seat moves up and down, be that guide cylinder linearly moves up and down along location cylinder, valve port and valve base chamber inclination are little, and aperture is large, closes tight, highly sensitive.This gas pressure regulator, governor is applicable to little pressure, large flow gas pipeline, simple to operate, easy for installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model gas pressure regulator, governor.
Embodiment
Structure and working principle below in conjunction with accompanying drawing to the utility model gas pressure regulator, governor are described in further details.
As shown in Figure 1, the utility model gas pressure regulator, governor comprises valve body 1, valve body 1 is with suction port 2 and air outlet 3, the valve seat 5 that is provided with valve port 4 in valve body 1 and matches with valve port 4, above valve seat 5, be provided with spring 6, the arranged outside of spring 6 has location cylinder 7, above valve seat 5, be provided with the guide cylinder 8 matching with location cylinder 7, the bottom surface of valve seat 5 is connected with valve rod 9, valve rod 9 bottoms regulate the diaphragm 11 in chamber 10 to be connected below with valve body 1, diaphragm 11 is divided into epicoele 101 and cavity of resorption 102 by adjusting chamber 10, suction port 2, epicoele 101 and cavity of resorption 102 are respectively by the first connecting tube 12, the second connecting tube 13, the 3rd connecting tube 14 is connected with restrictor 15, air outlet 3 is connected with pilot valve 17 by the 4th connecting tube 16, pilot valve 17 is connected with epicoele 101 by the 5th connecting tube 18.
When gas pressure regulator, governor provided by the utility model is used, combustion gas enters valve body 1 from suction port 2, combustion gas simultaneously also arrives restrictor 15 from suction port 2 by the first connecting tube 12, after restrictor 15, by the 3rd connecting tube 14, arrive cavity of resorption 102 again, cavity of resorption 102 pressure rises, upwards hold up diaphragm 11 and valve rod 9, valve seat 5 leaves valve port 4, combustion gas enters valve body 1 by valve port 4 and is gone out by air outlet 3, air outlet 3 pressure feed back to pilot valve 17 by the 4th connecting tube 16, by pilot valve 17, by the 5th connecting tube 18, feed back to epicoele 101 again, by epicoele 101, by the second connecting tube 13, feed back to restrictor 15 again, epicoele 101 and cavity of resorption 102 produce pressure balance, combustion gas is passed through.When air outlet, 3 pressure strengthen, and feed back to pilot valve 17, then by the 5th connecting tube 18, feed back to epicoele 101 by pilot valve 17 by the 4th connecting tube 16, epicoele 101 pressure rises, promote diaphragm 11 and valve rod 9 downwards, and valve seat 5 is near valve port 4, by combustion gas, reduce air outlet 3 pressure decreaseds.When air outlet, 3 pressure reduce, and by the 4th connecting tube 16, feed back to pilot valve 17, then by the 5th connecting tube 18, feed back to epicoele 101 by pilot valve 17, epicoele 101 pressure decreaseds, cavity of resorption 102 upwards holds up diaphragm 11 and valve rod 9, and valve seat 5 is away from valve port 4, by combustion gas, increase, air outlet 3 pressure raise.So adjust gas port 3 pressure, reach and control suction port 2 and the pressure balanced object in air outlet 3.And the arranged outside of spring 6 has location cylinder 7, above valve seat 5, be provided with the guide cylinder 8 matching with location cylinder 7.When valve seat 5 moves up and down, be that guide cylinder 8 linearly moves up and down along location cylinder 7, between valve port 4 and valve seat 5, inclination is little, and aperture is large, closes tight, highly sensitive.
