Abstract
The invention provides a check valve capable of prolonging the service life. The check valve comprises a valve body and a valve element. The valve element is connected to the upper portion of the valve body, and an inlet and an outlet of the valve body are formed in the two sides of the radial direction of the valve body respectively. A valve element hole from top to bottom is formed in a valve seat, and the valve element hole is connected with the inlet and the outlet of the valve body. An annular groove is formed in the position where the valve element and the valve element hole are connected, a sealing ring is connected to the annular groove, and the outer diameter part of the sealing ring protrudes out of the outer diameter part of the valve element. The annular groove containing the sealing ring is formed in the position of the valve element hole of a valve element body. According to the check valve capable of prolonging the service life, the starting pressure can be reduced, starting can be achieved without pressing equipment, and the service life of the check valve can be prolonged due to the special design of the valve element and the valve body.
Description
Technical field
The present invention relates to a kind of can the one-way valve of life-saving, belong to field of mechanical technique.
Background technique
In use easily there is the ineffective situation of break-make in existing one-way valve, therefore, needs to suppress the inlet of one-way valve, not only wasting manpower and material resources, but also bring a lot of trouble.And existing one-way valve is lower for working life, generally need at set intervals to change, wasting manpower and material resources and cost.Life-span low reason is that one-way valve cannot realize closing completely.
Summary of the invention
The invention provides a kind of can the one-way valve of life-saving, the above defect can be overcome, without the need to larger suppress pressure just can open check valve easily; Working life can extend.
For solving above technical problem, the invention provides following technological scheme: a kind of can the one-way valve of life-saving, described one-way valve comprises valve body, spool, and described spool is connected to valve body top, and the import of valve body and outlet are separately positioned on the radial both sides of valve body; Described valve seat is provided with spool bore from top to bottom, and this spool bore connects the export and import of valve body; Described spool and spool bore connection are provided with circular groove, and this circular groove place connects seal ring, and the external diameter of seal ring protrudes spool external diameter; The spool bore place of described valve core is provided with the circular groove holding seal ring.
Further, described one-way valve comprises push rod and elastic force seat, and push rod is connected to the inlet of valve body, push rod setting from top to bottom, push rod and the same axle center of spool; The bottom of described push rod connects elastic force seat, and elastic force seat is fixed in the valve seat orifice of valve body lower portion; The sidewall of described valve body has oilhole, and this oilhole communicates with the valve seat orifice of valve body lower portion.
Further, described elastic force seat is two, setting up and down, and the elastic force seat cross sectional area of top is less than the cross sectional area of the elastic force seat of below, and two elastic force seat concentrics.
Further, the material of described elastic force seat is for having thermal expansivity material.
Further, the material of described elastic force seat is rubber or metal.
The present invention relates to this can the one-way valve of life-saving, can cracking pressure be reduced, suppress equipment start without the need to using, due to the particular design of spool and valve body, be extended in the working life of one-way valve.
Accompanying drawing explanation
Fig. 1 is that the present invention is a kind of can the one-way valve structures schematic diagram of life-saving;
1-valve body; 2-spool; 3-import; 4-exports; 5-push rod; 6-upper elasticity seat; 7-down spring seat; 8-oilhole; 9-valve seat orifice; 10-seal ring.
Embodiment
As shown in Figure 1, a kind of can the one-way valve of life-saving, described one-way valve comprises valve body 1, spool 2, push rod 5, elastic force seat, and described spool 2 is connected to valve body 1 top, and the import 3 of valve body 1 and outlet 4 are separately positioned on the radial both sides of valve body; Described valve seat is provided with spool bore from top to bottom, and this spool bore connects outlet 4 and the import of valve body; Described push rod is connected to import 3 place of valve body, push rod 5 setting from top to bottom, push rod 5 and the same axle center of valve 2 core; The bottom of described push rod 5 connects elastic force seat, and elastic force seat is fixed in the valve seat orifice of valve body lower portion; The sidewall of described valve body has oilhole 8, this oilhole 8 communicates with the valve seat orifice 9 of valve body lower portion; Described spool 2 is provided with circular groove with spool bore connection, and this circular groove place connects seal ring 10, and the external diameter of seal ring 10 protrudes spool external diameter; The spool bore place of described valve core is provided with the circular groove holding seal ring; The material of described seal ring 10 is rubber.At spool, place restructures, and the spool after closedown can be made to be combined with valve body more tight, and the seal ring of quality of rubber materials easily makes spool open and close.Wherein seal ring is embedded in the circular groove of spool, and seal ring will protrude from the large footpath of spool, is convenient to it and enters circular groove on valve body, for compact siro spinning technology.Because bottom is provided with push rod, so without the need to worrying that one-way valve is not opened.
Described elastic force seat is two, setting up and down, and upper elasticity seat 6 cross sectional area is less than the cross sectional area of down spring seat 6, and two elastic force seat concentrics.
The material of described elastic force seat is for having thermal expansivity material.
The material of described elastic force seat is rubber or metal.
In figure, to be import 3, B be A in outlet 4, figure when deployed, PA often occurs and is greater than PB, by the top set of push rod with spool, thus the pressure of minimizing imported hydraulic oil.
Embodiment of the present invention does not form the restriction to the application's scope; within every spirit in the present invention's design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection scope of the present invention.
