Case steady voltage gas pressure regulator balances for voltage regulator inside through setting up the case sub -assembly, has eliminated the undulant and big or small impact of coming for the valve port flap of the velocity of flow of inlet pressure, has improved the precision of voltage regulation greatly, and the voltage regulator flow has also obtained promoting by a wide margin, has improved user's security.
Description
Technical field
The utility model belongs to gas transmission and distribution equipment technical field, particularly relates to the spool voltage stabilizing gas pressure regulator, governor that a kind of precision of voltage regulation is high.
Background technique
Rock gas needs to use gas pressure regulator, governor in course of conveying.Current gas pressure regulator, governor comprises the valve body being provided with and regulating chamber, valve port is provided with in valve body, regulate in chamber the voltage regulation diaphragm be provided with pressure regulation pallet, pressure adjusting spring and look nut is provided with above voltage regulation diaphragm, voltage regulation diaphragm is connected with valve rod by connecting rod, drive link, and valve stem tip is provided with valve pad.During use, combustion gas enters valve body by import, by exporting out after valve port.Under normal circumstances, the gas pressure below voltage regulation diaphragm in cavity and pressure adjusting spring are kept in balance, and valve pad and valve port keep certain distance.When change appears in gas pressure, the gas pressure below voltage regulation diaphragm in cavity is balanced with pressure adjusting spring to be broken, and voltage regulation diaphragm moves up and down, band ovable valve stem moves left and right, valve pad and valve port distance become large or diminish, thus regulate pressure governor outlet pressure, until close.The negotiability of this pressure governor is not fine, and the precision of voltage regulation is poor, runs not steady, brings unsafe factor to user.
Model utility content
Technical problem to be solved in the utility model is just to provide the spool voltage stabilizing gas pressure regulator, governor that a kind of negotiability is good, the precision of voltage regulation is high, operate steadily.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the valve body being provided with and regulating chamber, valve port is provided with in valve body, regulate in chamber the voltage regulation diaphragm be provided with pressure regulation pallet, pressure adjusting spring and look nut is provided with above voltage regulation diaphragm, voltage regulation diaphragm passes through connecting rod, drive link is connected with valve rod, valve stem tip is provided with valve pad, described valve stem top is provided with the guide sleeve with seal ring, guiding briquetting is provided with in guide sleeve, spring is provided with after guiding briquetting, be provided with balance film above, valve rod has the gas port making to communicate before and after balance film.
Spool voltage stabilizing gas pressure regulator, governor provided by the utility model, in pressure governor running, under normal circumstances, in valve body, gas pressure to be delivered to below voltage regulation diaphragm in cavity by gas port, gas pressure below voltage regulation diaphragm in cavity and pressure adjusting spring are kept in balance, and valve pad and valve port keep certain distance.When there is change in valve body gas pressure, in valve body, gas pressure change is delivered to below voltage regulation diaphragm by gas port, gas pressure below voltage regulation diaphragm in cavity is balanced with pressure adjusting spring to be broken, voltage regulation diaphragm moves up and down, voltage regulation diaphragm is moved left and right by connecting rod, drive link band ovable valve stem, drive valve pad and valve port distance become large or diminish while valve rod compression or extension spring, thus regulate pressure governor outlet pressure, until close.Spool voltage stabilizing gas pressure regulator, governor provided by the utility model, by arranging the spool assembly parts of guide sleeve, guiding briquetting, spring, balance film, gas port formation, balanced to pressure governor inside, eliminate the impact that inlet pressure fluctuates and flow velocity size is come to valve port rim strip, substantially increase the precision of voltage regulation, pressure governor flow have also been obtained and significantly promotes, and improves the Security of user.Its structure is simple, and volume is little, modular design, is convenient to I&M.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model spool voltage stabilizing gas pressure regulator, governor;
Fig. 2 is the structural representation of guide sleeve.
Embodiment
Below in conjunction with accompanying drawing, the structure of the utility model spool voltage stabilizing gas pressure regulator, governor and working principle are described in further details.
As shown in Figure 1, the utility model spool voltage stabilizing gas pressure regulator, governor comprises valve body 1, valve body 1 is provided with and regulates chamber 2, valve port 3 is provided with in valve body 1, regulate in chamber 2 voltage regulation diaphragm 5 be provided with pressure regulation pallet 4, voltage regulation diaphragm 5 is provided with pressure adjusting spring 6 and look nut 7 above, and voltage regulation diaphragm 5 is connected with valve rod 10 by connecting rod 8, drive link 9, and valve rod 10 top is provided with valve pad 11.As shown in Figure 2, valve rod 10 top is provided with valve pad 11, valve rod 10 top is provided with the guide sleeve 13 with seal ring 12, guiding briquetting 14 is provided with in guide sleeve 13, guiding briquetting 14 is provided with spring 15 below, is provided with balance film 16 above, and valve rod 10 has the gas port 17 making to communicate before and after balance film 16.
Spool voltage stabilizing gas pressure regulator, governor provided by the utility model, in pressure governor running, under normal circumstances, in valve body 1, gas pressure is delivered to voltage regulation diaphragm 5 below in cavity by gas port 17, gas pressure below voltage regulation diaphragm 5 in cavity and pressure adjusting spring 6 are kept in balance, and valve pad 11 and valve port 3 keep certain distance.When there is change in valve body gas pressure, in valve body 1, gas pressure change is delivered to below voltage regulation diaphragm 5 by gas port 17, gas pressure below voltage regulation diaphragm 5 in cavity is balanced with pressure adjusting spring 6 to be broken, voltage regulation diaphragm 5 moves up and down, voltage regulation diaphragm 5 is with ovable valve stem 10 to move left and right by connecting rod 8, drive link 9, valve rod 10 compresses or drives valve pad 11 and valve port 3 apart from becoming large or diminishing while extension spring 15, thus regulates pressure governor outlet pressure, until close.
The utility model is not limited only to above-mentioned form, but no matter is adopt which kind of form, as long as structure is identical with the utility model, all falls into protection domain of the present utility model.
