Abstract

The utility model discloses a check valve. The check valve comprises a valve body, wherein an inner cavity of the valve body is provided with an oil feeding cavity, a transitional cavity and an oil discharging cavity in sequence from left to right; the oil discharging valve is internally provided with a valve body component; a ring-shaped inclined surface is arranged at the connecting position of the oil feeding cavity and the transitional cavity; a sealing ring is arranged on the ring-shaped inclined surface and is internally provided with a layer of metal mesh in a sheathing manner; the metal mesh is in an inverted frustum shape; and an own ring-shaped embedding edge of the metal mesh is wedged with the bottom surface of the oil feeding cavity. The check valve disclosed by the utility model has the advantages that the structure is simple, the sealing performance is excellent, the phenomenon of oil leakage can be effectively solved, and more convenience is achieved when internal parts are disassembled and assembled for replacement.

Description

A kind of one-way valve
Technical field
The utility model relates to valve field, particularly a kind of one-way valve.
Background technique
One-way valve claims again safety check or check valve.Be used for hydraulic system and prevent oil stream reverse flow, perhaps be used for pneumatic system and prevent the pressurized air reverse flow.Its effect is to prevent medium directional flow in the pipeline and the function of unlikely refluence, existing safety check does not arrange filtrating equipment, cause the impurity in the oil directly to enter machine and part friction, cause the part friction in the machine seriously to cause damaging, affected greatly the life-span that machine uses, and existing product adopts steel ball as non return part, before not adding grease injection, residual air (oil gas) effect in the valve pocket is lower, and one-way valve can produce leakage situation, very easily has an accident.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple in structure, is convenient to disassembling, assembling and replacing, and the one-way valve of good sealing effect.
To achieve these goals, the technical solution of the utility model is as follows: a kind of one-way valve, comprise valve body, described body cavity offers successively from left to right oil suction chamber, adapter cavity and goes out oil pocket, goes out valve component is installed in the oil pocket, and described oil suction chamber and adapter cavity junction point offer a loop inclined-plane, on the loop inclined-plane seal ring is installed, the seal ring inner sleeve has the layer of metal net, and described wire netting is the inverted round stage shape, and agree with the ring-type fringing that carries of wire netting and the bottom surface of oil suction chamber.
Preferably, described valve component comprises cone valve and the spring of being located at the cone valve afterbody.
Preferably, the outlet port of described adapter cavity is provided with rubber ring, and rubber ring sleeve is located on the valve point of cone valve.
Adopt the one-way valve of technique scheme, because described oil suction chamber and adapter cavity junction point are offered a loop inclined-plane, one seal ring is installed on the ring-type inclined-plane, seal ring inner sleeve layer of metal net, described wire netting is the inverted round stage shape, and agree with the ring-type fringing that carries of wire netting and the bottom surface of oil suction chamber.And the outlet port of described adapter cavity is provided with rubber ring, and rubber ring sleeve is located on the valve point of cone valve, so the double-layer seal mode can reach good sealing effect, effectively solves oil leakage phenomenon, simultaneously more convenient when the disassembling, assembling and replacing inner body, save trouble.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the attached structural representation of the utility model.
Coding among the figure is respectively: 1 is valve body, and 2 is oil suction chamber, and 3 is adapter cavity, and 4 for going out oil pocket, and 5 is seal ring, and 6 is wire netting, and 7 is the ring-type fringing, and 8 is cone valve, and 9 is spring, and 10 is rubber ring.
Embodiment
As shown in Figure 1, a kind of one-way valve, comprise valve body 1, described valve body 1 inner chamber offers successively from left to right oil suction chamber 2, adapter cavity 3 and goes out oil pocket 4, goes out in the oil pocket 4 valve component is installed, and described oil suction chamber 2 is offered a loop inclined-plane with adapter cavity 3 junction points, on the ring-type inclined-plane seal ring 5 is installed, seal ring 5 inner sleeves have layer of metal net 6, and described wire netting 6 is the inverted round stage shape, and the ring-type fringing that carries 7 of wire netting 6 agrees with the bottom surface of oil suction chamber 2.
As shown in Figure 1, described valve component comprises cone valve 8 and the spring 9 of being located at cone valve 8 afterbodys.
As shown in Figure 1, the outlet port of described adapter cavity 3 is provided with rubber ring 10, and rubber ring 10 is sheathed on the valve point of cone valve 8.
One-way valve of the present utility model, because oil suction chamber 2 is offered a loop inclined-plane with adapter cavity 3 junction points, on the loop inclined-plane seal ring 5 is installed, seal ring 5 inner sleeves have layer of metal net 6, wire netting 6 is the inverted round stage shape, and the ring-type fringing that carries 7 of wire netting 6 agrees with the bottom surface of oil suction chamber 2.And the outlet port of adapter cavity 3 is provided with rubber ring 10, and rubber ring 10 is sheathed on the valve point of cone valve 8, so the double-layer seal mode can reach good sealing effect, effectively solves oil leakage phenomenon, simultaneously more convenient when the disassembling, assembling and replacing inner body, save trouble.
