Abstract
The utility model relates to a high pressure gas regulator which comprises a main valve and a director connected with the main valve, wherein, the upper part of the main valve is provided with an actuating mechanism composed of an upper film casing, a lower film casing, a rubber diaphragm and a valve rod, and the lower part of the main valve is connected with a valve body, the inner part of which is provided with a value port and the bottom is provided with a valve cap, through a transition sleeve, wherein, the lower end of the valve port and a nut of the valve port are connected; the valve port is matched with a valve pad. The utility model is characterized in that a circle of screw holes are arranged on the nut of the valve port and fastened with the valve body through screws; no arc is arranged on the valve port; the valve pad forms a frustum shape and is made of polytetrafluoroethylene material. The utility model has the advantages of reliable seal, simple manufacturing process and convenient fabrication of parts; the utility model effectively prevents the valve port from looseness and is suitable for the pressure regulating of high pressure gas.
Description
Technical field
The utility model relates to a kind of gas pressure regulating valve door.
Background technique
Existing gas pressure regulating valve can not satisfy its sealability in the pressure regulation process of high-pressure gas.Its structure comprises main valve and the pilot valve that is connected with main valve, the actuator that its main valve top is made up of last putamina, lower shell, elastomer diaphragm, valve rod, the main valve bottom connects inside by spacer shell has valve port, bottom that the valve body of valve gap is arranged, wherein the valve port lower end is threaded with valve body, under the impact of high pressure draught, part produces vibration with air-flow, and the valve port long-term work gets loose easily; Valve port portion is that circular arc cooperates with valve pad in addition, and circular arc valve port processes difficulty is big.
Technology contents
The utility model solves high-pressure gas pressure regulator valve valve port difficulty of processing technical problem big, that get loose with the valve body ease of connection, to be fit to the high-pressure gas pressure regulation.
The technological scheme of the utility model high-pressure gas pressure regulator valve: comprise main valve and the pilot valve that is connected with main valve, the actuator that its main valve top is made up of last putamina, lower shell, elastomer diaphragm, valve rod, the main valve bottom connects inside by spacer shell has valve port, bottom that the valve body of valve gap is arranged, wherein the valve port lower end is connected with the valve port nut, valve port cooperates with valve pad, it is characterized in that: a circle screw hole is arranged on the valve port nut, fastening by screw and valve body.
Its valve port inner face is a plane shape, and valve pad is the taper type of being made by polytetrafluoroethylmaterial material.
Beneficial effect: when diaphragm lower end gas pressure increased, under the effect of gas pressure, diaphragm rose, and overcame that acting force of the spring drives valve rod and sleeve also rises, and at this moment, valve pad and valve port are opened, and the size of valve port opening is relevant with the pressure reduction on the diaphragm.The bottom is a valve body, and except that circulated gases, other part is fixed in the above.
The means of fixation of valve port: the valve port lower end tightens at valve body with screw thread and valve port nut, 8 M6 tapped holes are arranged in a week on the edge of valve port nut, and tighten with 8 screws and valve body, this simple measures has prevented that effectively valve port is loosening, is applicable to the pressure regulation of high-pressure gas.Valve port is the straight line valve port, does not have circular arc on it, and valve pad adopts polytetrafluoroethylmaterial material, and becomes taper type.Sealing is reliable like this, and process treating is simpler than in the past, and part processing is also than easy, convenient in the past.Be fit to the high-pressure gas pressure regulation.
