Abstract
The utility model discloses a highly reliable one-way valve, which comprises a spring, a valve element, a valve seat, a valve body, an inlet, an outlet and a hole, wherein the spring, the valve element and the valve seat arranged in the valve body are successively connected; the inlet and the outlet are respectively arranged at the two ends of the valve body; the hole is radially arranged on the valve element; and the spring, the valve element and the valve seat are located on the same straight line. The one-way valve disclosed by the utility model has the beneficial effect that through controlling the force applied to the spring by the valve element, the reverse flow of oil liquid is prevented, and the valve is simple in structure, reliable in performance and good in sealing property.
Description
Technical field
The utility model 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.
The model utility content
The model utility purpose: the purpose of the utility model is in order to solve the deficiency of existing technology, to provide a kind of simple in structure, reliable performance, the electromagnetic expanding valve that sealability is good.
Technological scheme: in order to realize above purpose, the described a kind of highly reliable one-way valve of the utility model, 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 that the utility model provides, 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 the sectional view of the utility model.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model.
Be illustrated in figure 1 as the described a kind of highly reliable one-way valve of the utility model, 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 the technical conceive and the characteristics of explanation the utility model, its objective is to let to be familiar with the also enforcement according to this of content that these those skilled in the art can understand the utility model, can not limit the protection domain of the utility model with this.All equivalents or modifications of having done according to the utility model spirit all should be encompassed within the protection domain of the utility model.
