Abstract

With the self-contained pressure regulator of pilot valve.Traditional self-contained pressure regulator needs manually or Mechanical course, the ability of pilot pressure fluctuating range is little, the utility model composition comprises: the main valve plug (6) of main valve (5) is connected with valve rod (7), valve rod is connected with push rod (8), push rod and main valve film perform feeler mechanism (11) and are connected, main valve film execution feeler mechanism is performed feeler mechanism (2) with pilot valve film and is connected by linkage section (12), adapter A(3) main valve is communicated with linkage section, adapter B(13) main valve film execution feeler mechanism is communicated with linkage section, adapter C(14) main valve and main valve film are performed feeler mechanism be communicated with, the spool (10) that pilot valve film performs the pilot valve (1) that feeler mechanism installs is deep in linkage section, the port of adapter A is higher than the port of adapter B, adapter A is provided with reduction valve (4).The utility model is used for self-contained pressure regulator.

Description

With the self-contained pressure regulator of pilot valve
technical field:
the utility model relates to a kind of self-contained pressure regulator with pilot valve.
background technique:
traditional self-contained pressure regulator needs manually or Mechanical course, and the ability of its pilot pressure fluctuating range is little, and downstream pressure is non-constant, owing to dropping into manpower or machinery, can not accomplish energy saving in the control of modulating valve.
model utility content:
the purpose of this utility model is to provide a kind of self-contained pressure regulator with pilot valve.
above-mentioned object is realized by following technological scheme:
a kind of self-contained pressure regulator with pilot valve, its composition comprises: main valve, main valve plug in described main valve is connected with valve rod, described valve rod is connected with push rod, described push rod and main valve film perform feeler mechanism and are connected, described main valve film execution feeler mechanism is performed feeler mechanism with pilot valve film and is connected by linkage section, cavity on the left of described main valve is communicated with described linkage section by adapter A, described main valve film is performed feeler mechanism and is communicated with described linkage section by adapter B, cavity on the right side of described main valve is performed feeler mechanism with described main valve film and is communicated with by adapter C, described pilot valve film performs in feeler mechanism and is provided with pilot valve, the pilot valve spool of described pilot valve is deep in described linkage section the opening and closing of the adapter A described in controlling and described adapter B port, the port of described adapter A is higher than the port of described adapter B, described adapter A is provided with reduction valve, described adapter B is provided with throttle valve.
beneficial effect:
1. the utility model is without the need to external energy, utilizes by the change of tune medium pressure own and realizes automatically regulating, making downstream pressure constant, and complete machine has and is active in one's movements, and pilot pressure fluctuation is little, the features such as energy saving.The utility model belongs to Self-operated valve series, the pressure of medium self is utilized to carry out control valve switch, adopt leading type structure, there are two diaphragm actuators (pilot valve feeler mechanism and each one of main valve feeler mechanism), the not direct control bound core of downstream pressure, but the Kai Heguan of pilot valve actuating mechanism controls valve main valve.
the utility model adopts the method for power source and signaling point separate detection, and additional adjustable device, the degree of regulation of whole deck valve door is improved greatly, and Pressure reducing ratio is maximum reaches 2000:1.Be particularly suitable as nitrogen envelope for nitrogen valve, have the pressure surge of lasting confession nitrogen little, the feature such as be quick on the draw.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
embodiment:
embodiment 1:
a kind of self-contained pressure regulator with pilot valve, its composition comprises: main valve 5, main valve plug 6 in described main valve is connected with valve rod 7, described valve rod is connected with push rod 8, described push rod and main valve film perform feeler mechanism 11 and are connected, described main valve film execution feeler mechanism is performed feeler mechanism 2 with pilot valve film and is connected by linkage section 12, adapter A, piece number: the cavity on the left of described main valve is communicated with described linkage section by 3, adapter B, piece number: described main valve film is performed feeler mechanism by 13 to be communicated with described linkage section, adapter C, piece number: the cavity on the right side of described main valve is performed feeler mechanism with described main valve film by 14 to be communicated with, described pilot valve film performs in feeler mechanism and is provided with pilot valve 1, the pilot valve spool 10 of described pilot valve is deep in described linkage section the opening and closing of the adapter A described in controlling and described adapter B port, the port of described adapter A is higher than the port of described adapter B, described adapter A is provided with reduction valve 4, described adapter B is provided with throttle valve 9.
