Description
Technical field
A kind of high pressure direct proportion valve is the utility model is related to, suitable for High Pressure Air Compressor system.
Background technology
At present, gas is commonly low pressure proportioning valve with direct proportion valve, and the air compressor machine of 16bar is no more than suitable for pressure, its
Feature is that working pressure range is low, and the most pressure containing disk used is rubber diaphragm, its short life, and outlet pressure compares
Easily influenced be subject to inlet pressure, output characteristics is poor.
The content of the invention
Deficiency the purpose of this utility model is to overcome more than, there is provided a kind of having stable behavior, long lifespan, output characteristics
Stable high pressure direct proportion valve.
The purpose of this utility model is achieved through the following technical solutions：A kind of high pressure direct proportion valve, including valve body and valve
Lid, is equipped with gasket between valve body and valve deck, pressure entrance and pressure export are equipped with valve body, spring base, spring are equipped with valve deck
Spring is equipped with seat, red copper diaphragm unit is equipped between gasket and spring base, sealing ring is equipped between spring base and valve body.
Further improvement of the utility model is：Red copper diaphragm unit is pressed on gasket by pressure ring.
Further improvement of the utility model is：Spring base is fixed in valve deck by adjusting bolt and locking nut.
Further improvement of the utility model is：The rectangular cross-section of spring.
Further improvement of the utility model is：Pressure ring orifice shapes are transition shape large-diameter circular arcuation.
The utility model has the following advantages compared with prior art：
The utility model highest can be used for 40bar air compressor systems, and under maximum load, having stable behavior, long lifespan can
After frequent switching motion, good output characteristics is still ensured that, operating pressure is precisely stablized.
Brief description of the drawings：
Fig. 1 is：The structure diagram of the utility model；
Figure label：1- valve bodies, 2- valve decks, 3- gaskets, 4- pressure entrances, 5- pressure exports, 6- spring bases, 7- springs,
8- red coppers diaphragm unit, 9- sealing rings, 10- pressure rings, 11- adjusting bolts, 12- locking nuts.
Embodiment：
, below will be to the utility model to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Technical solution in embodiment is clearly and completely described, it is clear that described embodiment is that the utility model part is real
Example is applied, instead of all the embodiments.Elements and features described in a kind of embodiment of the utility model can be with one
The elements and features shown in a or more other embodiment is combined.It should be noted that for purposes of clarity, in explanation
Eliminate the expression and description of component unrelated with the utility model, known to persons of ordinary skill in the art and processing.It is based on
Embodiment in the utility model, the institute that those of ordinary skill in the art are obtained on the premise of not making the creative labor
There is other embodiment, shall fall within the protection scope of the present invention.
As Fig. 1 shows a kind of embodiment of the utility model high pressure direct proportion valve, including valve body 1 and valve deck 2, valve body
Gasket 3 is equipped between 1 and valve deck 2, pressure entrance 4 and pressure export 5 are equipped with valve body 1, spring base 6, spring are equipped with valve deck 2
Spring 7 is equipped with seat 6, red copper diaphragm unit 8 is equipped between gasket 3 and spring base 6, sealing is equipped between spring base 6 and valve body 1
Ring 9, spring base 6 are fixed in valve deck 2 by adjusting bolt 11 and locking nut 12.
Red copper diaphragm unit 8 is pressed on gasket 3 by pressure ring 10, and 10 orifice shapes of pressure ring are transition shape large diameter circular arc
Shape, ensures red copper diaphragm repeated deformation and is unlikely to fatigue fracture.
The rectangular cross-section of spring 7, spring 7 solve spring under big stress using this special cross-section steel wire manufacture spring
The problem of power declines.
The utility model highest can be used for 40bar air compressor systems, and under maximum load, having stable behavior, long lifespan can
After frequent switching motion, good output characteristics is still ensured that, operating pressure is precisely stablized.
Finally it should be noted that：Although the utility model and its advantage are described in detail above it should be appreciated that
Various change can be carried out in the case of without departing from the spirit and scope of the utility model being defined by the claims appended hereto
Become, substitute and convert.Moreover, the scope of the utility model is not limited only to the described process of specification, equipment, means, method
With the specific embodiment of step.One of ordinary skilled in the art will readily appreciate that from the disclosure of the utility model, root
It can be used according to the utility model and perform the function essentially identical to corresponding embodiment described herein or obtain basic with it
Identical result, existing and to be developed in the future process, equipment, means, method or step.Therefore, appended right
It is required that include such process, equipment, means, method or step in the range of being directed at them.
