Abstract
The invention provides a check valve capable of reducing starting pressure. The check valve comprises a valve body, a valve element, an ejector rod and elastic seats. 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 seat is provided with a valve element hole from top to bottom, and the valve element hole is connected with the outlet and the inlet of the valve body. The ejector rod is connected to the inlet of the valve body, the ejector rod is arranged from top to bottom, and the ejector rod and the valve element share the same axis. The bottom of the ejector rod is connected with the elastic seats which are fixed in a valve seat hole in the lower portion of the valve body. An oil hole is formed in the side wall of the valve body, and the oil hole and the valve seat hole in the lower portion of the valve body are communicated. According to the check valve capable of reducing the starting pressure, the starting pressure can be reduced, starting is achieved without pressing equipment, and the check valve is reasonable in structure and wide in application range.
Description
Technical field
The present invention relates to a kind of one-way valve reducing breakout pressure, 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.How this kind of one-way valve can be become one by a less change uses less pressure spool can be backed down, and is the problem that the application will study.
Summary of the invention
The invention provides a kind of one-way valve reducing breakout pressure, the above defect can be overcome, without the need to larger suppress pressure just can open check valve easily.
For solving above technical problem, the invention provides following technological scheme: a kind of one-way valve reducing breakout pressure, described one-way valve comprises valve body, spool, push rod, elastic force seat, 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 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.
This one-way valve reducing breakout pressure that the present invention relates to, can reduce cracking pressure, suppresses equipment start without the need to use, for one is rational in infrastructure, and widely used one-way valve.
Accompanying drawing explanation
Fig. 1 is a kind of one-way valve structures schematic diagram reducing breakout pressure of the present invention;
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.
Embodiment
As shown in Figure 1, a kind of one-way valve reducing breakout pressure, 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 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.
