Description
Technical field
The utility model relates to pressure regulator technical field more particularly to a kind of small-size shaft stream pressure regulators.
Background technique
Existing axial flow pressure regulator lowest calibre is 25mm, and structure is complicated, is applied to high pressure voltage regulating station more, is carried out
Big flow Regulation Control.Flow does not have axial flow pressure regulator in 200 sides pressure regulator below.
Summary of the invention
To the above-mentioned state of the art, the technical problem to be solved by the utility model is to provide one kind to be directed to small stream
Measure the small-size shaft stream pressure regulator of axis stream.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of small-size shaft stream pressure regulator, including
Shell, the casing centerline are equipped with sleeve valve port, and the sleeve valve port is equipped with push rod, is equipped with diaphragm above the push rod
Component, the diaphragm unit top are equipped with pressure regulator spring, which offsets with the inner walls, described to push away
Guiding ram seat is cased on bar, the guiding ram seat lower end surface has been embedded in valve port pad, and the sleeve valve port is placed in the valve
Mouth pad lower section.
Further, the sleeve valve port housing has guided seat.
Further, sealing ring is equipped between the sleeve valve port and guided seat.
Further, it is input end that the shell lower end, which is equipped with, and the sleeve valve port is placed in input end, the shell side
Equipped with outlet end, the outlet end and the input end are perpendicular.
Further, it is described guiding ram seat side be equipped with hollow pipe, for by outlet pressure introduce diaphragm unit and
The lower chambers of shell composition.
Compared with the prior art, the advantages of the utility model are: the utility model has filled up pressure regulator for small flow
The blank section of the demand of axis stream, and design rationally, it can large-scale promotion.
Detailed description of the invention
Fig. 1 is a kind of small-size shaft stream pressure regulator structural schematic diagram of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As shown, a kind of small-size shaft stream pressure regulator, including shell 1,1 center line of shell are equipped with sleeve valve port 9,
The sleeve valve port 9 is equipped with push rod 4, and diaphragm unit 2 is equipped with above the push rod 4, is equipped with pressure regulation above the diaphragm unit 2
Device spring 3,3 upper end of pressure regulator spring offset with 1 inner wall of shell, and guiding ram seat 5 is cased on the push rod 4, described
Guiding 5 lower end surface of ram seat has been embedded in valve port pad 6, and the sleeve valve port 9 is placed in 6 lower section of valve port pad, the telescoping valve
It is cased with guided seat 5 outside mouth 9, sealing ring 8 is equipped between the sleeve valve port 9 and guided seat 7,1 lower end of shell is equipped with
For input end 10, the sleeve valve port 9 is placed in input end 10, and 1 side of shell is equipped with outlet end 11, the outlet end 11 and institute
State that input end 10 is perpendicular, the side of the guiding ram seat 5 is equipped with hollow pipe 12, for outlet pressure to be introduced diaphragm unit
2 and shell 1 form lower chambers 13, gas pressure on diaphragm unit 2 and pressure regulator spring 3 formed balance exercise, diaphragm group
Part 2 drives sleeve valve port 9 to move up and down, and controls valve port opening, changes outlet pressure and flow therewith.
When pressure regulator input end 10 is ventilated, air-flow flows directly into outlet by the runner that sleeve valve port 9 and valve port pad 6 are formed
11 are held, the skirt on guided seat 7 introduces the air pressure for flowing to outlet end 10 in the chamber that shell 1 and diaphragm unit 2 are formed, gas
Pressure acts on diaphragm unit 2 and pressure regulator spring 3 acts on the power formation balance exercise of diaphragm unit 2, and diaphragm unit 2 passes through
Push rod 4 drives sleeve valve port 9 to move up, to change valve port pad 6 and the formation airflow path size of sleeve valve port 9, makes to export
Pressure is smaller, when to act on the power on diaphragm unit 2 flat for the power that acts on diaphragm unit 2 of outlet air pressure and pressure regulator spring 3
When weighing apparatus, 9 aperture of sleeve valve port is fixed.Pressure regulator enters normal operating conditions.When outlet pressure changes, the set of pressure regulator
The aperture of cylinder valve port 9 accordingly changes, and completes throttling pressure regulation effect.
Compared with the prior art, the advantages of the utility model are: the utility model has filled up pressure regulator for small flow
The blank section of the demand of axis stream, and design rationally, it can large-scale promotion.
