Abstract
The invention discloses a high-reliability one-way valve, which comprises a spring, a valve spool, a valve seat, a valve body, an inlet, an outlet and a hole. The spring, the valve spool and the valve seat are arranged inside the valve body and are sequentially connected, the inlet and the outlet are arranged at two ends of the valve body respectively, the hole is radially arranged on the valve spool, the spring, the valve spool and the valve seat are positioned on the same straight line, the one-way valve controls force acting on the spring through the valve spool, reverse flow of oil is prevented, and the one-way valve is simple in structure, reliable in performance and excellent in sealing performance.
Description
Technical field
The present invention relates to a kind of highly reliable one-way valve.
Background technique
In hydraulic system,, often adopt one-way valve in order to prevent the fluid reverse flow; Because of mostly oil hydraulic circuit is hyperbaric environment, one-way valves a lot of on the market have not caused system leak because of sealability is good, influence Security, the reliability of this system works; And having caused the waste of fluid, the environment around having polluted has increased downtime of machine; Reduced productivity, increased cost of production and product has been caused stained.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of simple in structure in order to solve the deficiency of existing technology, reliable performance, the electromagnetic expanding valve that sealability is good.
Technological scheme: in order to realize above purpose, a kind of highly reliable one-way valve of the present invention, it comprises spring, spool; Valve seat, valve body, inlet, outlet and hole; The spring that is provided with in the described valve body, spool, valve seat link to each other successively, and two ends of valve body is respectively equipped with entrance and exit; Described hole radially is located on the spool, described spring, and spool and valve seat are located along the same line.
Beneficial effect: a kind of highly reliable one-way valve provided by the invention, through the power of spool control action on spring, realized preventing the reverse flow of fluid, and simple in structure, reliable performance, sealability is good.
Description of drawings
Fig. 1 is a sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
Be illustrated in figure 1 as a kind of highly reliable one-way valve of the present invention, it comprises spring 1, spool 2, valve seat 3, valve body 4, inlet 5, outlet 6 and hole 7.
The spring 1 that is provided with in the described valve body 4, spool 2, valve seat 3 link to each other successively, and the two ends of valve body 4 are respectively equipped with inlet 5 and outlet 6, and described hole 7 radially is located on the spool 2, described spring 1, and spool 2 is located along the same line with valve seat 3.
When air-flow 5 gets into valve bodies 4 from entering the mouth; Gas pressure overcomes the frictional force of spring force between spool 2 and valve body 4 of spring 1, when spool 2 to moving to left, air-flow 5 flows out from exporting 6 through hole 7 from entering the mouth; Realized entering the mouth 5 with the communicating of outlet 6; Mobile in order to ensure steady air current, inlet 5 should remain on certain pressure difference with outlet 6, and spool 2 is held open.When air-flow was reverse, spool 2 moved to right under outlet 6 chamber air pressure and spring force effect, and inlet 5 is closed with outlet 6.
This one-way valve has realized preventing the reverse flow of fluid through the spring force of spool 2 control actions on spring 1, and simple in structure, reliable performance, and sealability is good.
Above-mentioned embodiment only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
