Abstract

The utility model relates to a direct-acting fixed-value pressure reducing valve. Thedirect-acting fixed-value pressure reducing valve comprises a valve body, a valve core, a spring seat, a spring and two identical screw plugs, wherein the valve core is mounted in a through hole of the valve body; one end, in which a tapered hole is formed, of the valve core is matched with the spherical surface of the spring seat for mounting; the spring is mounted betweenthe spring seat and one screw plug, and the distance between the spring seat and the screw plug enables the spring to have a certainpre-compression amount; the other end of the valve core is attached to the other screw plug under the effect of the pre-compression force of the spring. Compared with other products adopting same kinds of structures, the direct-acting fixed-value pressure reducing valve has the advantages of small, exquisite and attractive appearance, simplestructure, convenience in mounting, good repeatability, stable performance and capability of meeting the requirement for mass production.

Description

A kind of direct-acting type Fixed pressure reducing valve
Technical field
The utility model belongs to reduction valve field, particularly relates to a kind of direct-acting type Fixed pressure reducing valve.
Background technique
Direct acting pressure class overall volume is all larger in the market, and installation institute takes up space larger, has increased the weight of whole valve, and very not attractive in appearance.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of direct-acting type Fixed pressure reducing valve, to solve larger, the heavier problem of original reduction valve volume.
The utility model solves the technological scheme that its technical problem adopts: a kind of direct-acting type Fixed pressure reducing valve is provided, comprise valve body, spool, in the through hole of valve body, spool is installed, described spool one end is taper hole end, taper hole end coordinates installation with the protrusion hemisphere of spring seat bottom center, spring seat and be fixed between the screw plug of valve body one side end face spring is installed, the other end of spool withstands the screw plug of valve body opposite side end face.Spool has one end of taper hole and the sphere of spring seat to coordinate installation, and the lateral force producing can avoid spring-compressed like this time causes spring seat stressed, and then affects valve core movement, and this structure has advantages of reproducible, stable performance.
Described spring has pre compressed magnitude.
On described valve body, there are some oil throughs.Spool is after valve passes into the hydraulic oil of certain pressure, the spring force producing after the oil liquid pressure of exporting by spool and spring-compressed matches, and because spring rate and decrement all keep constant, so the oil liquid pressure of spool output also remains certain value, not disturbed by charge oil pressure and induced pressure.This valve profile is small and exquisite attractive in appearance, simple for structure, easy for installation, reproducible, and stable performance can meet production in enormous quantities.
Beneficial effect
It is small and exquisite attractive in appearance, simple for structure, easy for installation, reproducible that the utility model has profile compared with other infrastructure products of the same type, and stable performance, can meet production in enormous quantities.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Fig. 1~5, a kind of direct-acting type Fixed pressure reducing valve, comprises valve body 1, spool 2, spring seat 3, spring 4 and two identical screw plugs 5.Described spool 2 is after valve passes into the hydraulic oil of certain pressure, the spring force producing after the oil liquid pressure of exporting by spool 2 and spring 4 compressions matches, and because spring rate and decrement all keep constant, so the oil liquid pressure that spool 2 is exported also remains certain value, not disturbed by charge oil pressure and induced pressure.
