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 flow is little, adopts multi-channel parallel, and cost is high, and management difficulty is large, and aperture is little, takes up room large, and maintenance is complicated, maintenance expenses costliness.
Model utility content
Technical problem to be solved in the utility model is just to provide that a kind of flow is large, pressure range is wide, cost of production and maintenance cost is low, volume is little, highly sensitive, simple to operate gas pressure regulator, governor.
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 connected with pilot valve by the first connecting tube, the second connecting tube, the 3rd connecting tube respectively, and epicoele is connected with air outlet by the 4th 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 pilot valve from suction port by the first connecting tube, after pilot valve, 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 epicoele by the 4th connecting tube, by epicoele, by the second connecting tube, feed back to pilot valve again, epicoele and cavity of resorption produce pressure balance, and combustion gas is passed through.When air outlet pressure strengthens, 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 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, realize pressure regulation.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 flow is large, pressure range is wide, strong adaptability, cost of production and maintenance cost is low, volume is little, highly sensitive, 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 pilot valve 15, epicoele 101 is connected with air outlet 3 by the 4th connecting tube 16.
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 pilot valve 15 from suction port 2 by the first connecting tube 12, after pilot valve 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 epicoele 101 by the 4th connecting tube 16, by epicoele 101, by the second connecting tube 13, feed back to pilot valve 15 again, epicoele 101 and cavity of resorption 102 produce pressure balance, combustion gas is passed through.When air outlet, 3 pressure strengthen, and epicoele 101 pressure rises promote diaphragm 11 and valve rod 9 downwards, and valve seat 5, near valve port 4, reduces by combustion gas, air outlet 3 pressure decreaseds.When air outlet, 3 pressure reduce, epicoele 101 pressure decreaseds, and cavity of resorption 102 upwards holds up diaphragm 11 and valve rod 9, and valve seat 5, away from valve port 4, increases by combustion gas, and air outlet 3 pressure raise.So adjust gas port 3 pressure, realize pressure regulation.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, close tight, highly sensitive.
The gas pressure regulator, governor that the utility model provides is not limited only to said structure, as long as structure is identical with the utility model, all falls into the utility model protection domain.
