Abstract

Dustproof safety valve, conical valve base front portion are provided with installation set, set and conical valve base elastic conjunction, install accurate filter screen on the inner face of set, install coarse strainer on the inside of accurate filter screen.The dustproof safety valve of the present invention, fills two-layer filter screen in aperture front end, it is ensured that filter screen can not be deformed and dropped off in the presence of oil pressure, ensured the reliability of steering pump application.

Description

Dustproof safety valve
Technical field
The present invention relates to component of machine technical field, more particularly to hydraulic pump parts technical field.
Background technology
With continuous application of the hydraulic technique in automobile industry, automotive steering regiment commander's hydraulic booster is more and more, root Design processing 1 millimeter of aperture of diameter on pump configuration is needed according to performance requirement, as fluid is contaminated, aperture is easily blocked, Install screen pack additional again yielding or come off, lose power steering function, reduce steering boost system functional reliability, be behaviour Author brings inconvenience.
Content of the invention
For the problems referred to above for overcoming existing hydraulic pump aperture to exist, the invention provides a kind of high dust protected of reliability Safety valve.
The technical scheme that adopted for achieving the above object of the present invention is：Dustproof safety valve, 4 front portion of conical valve base are provided with peace Encapsulation 1, installs accurate filter screen 2 on the inner face of set, install coarse strainer 3 on the inside of accurate filter screen 2.
The set 1 and 4 elastic conjunction of conical valve base.
The dustproof safety valve of the present invention, fills two-layer filter screen in aperture front end, it is ensured that filter screen can not in the presence of oil pressure Deform and drop off, ensured the reliability of steering pump application.
Description of the drawings
Fig. 1 is dustproof safety valve structure chart of the present invention.
Specific embodiment
The dustproof safety valve structure of the present invention is as shown in figure 1,4 front portion of conical valve base is provided with installation set 1, set 1 and conical valve base 4 Elastic conjunction, accurate filter screen 2 are sintered in pressing fit in cone valve bore, i.e., straight on the end face of set and together with set with coarse strainer 3 1 millimeter of footpath aperture front end is equipped with 2 metafiltration nets, and ground floor refined filtration net causes 1 millimeter opening not blocked by particulate matter, second layer coarse strainer Mainly play a supportive role, it is ensured that filter screen can not be deformed and dropped off in the presence of oil pressure, be able to the reliability of steering pump application Ensure.
