Abstract
The utility model discloses a kind of O-ring seal welding type check valves of check valve technical field, including valve body, sliding sleeve skeleton is provided on the left of the inner cavity of the valve body, socket is provided with spring on the sliding sleeve skeleton, it is provided with the sliding sleeve seal head to match with sliding sleeve skeleton on the right side of the inner cavity of the valve body, and is provided with O-ring, negative-pressure sealing on sliding sleeve seal head, it can directly be welded, and to the advantages such as welding process requirement is low.
Description
Technical field
The utility model relates to check valve technical field, specially a kind of O-ring seal welding type check valve.
Background technique
There are two main classes for domestic similar product, and one kind cannot be welded directly to be sealed using O-ring, needs
First union is welded on pipeline, is connected by check valve and slip-knot, if the bad of welding may result in unidirectionally
Valve thread biting locking, valve are scrapped, and will lead to more than valve leakage point at one, and this check valve volume using gasket seal
Greatly, far super 1.5 times of product emblem mark or more declared of length, another kind is hard leakproof one-way valve, hard leakproof one-way valve processing request
Height, welded type note also that cooling cannot allow sealing surface to deform, and under low pressure and negative pressure condition, cannot achieve sealing, be
This, it is proposed that a kind of O-ring seal welding type check valve.
Utility model content
The purpose of this utility model is to provide a kind of O-ring seal welding type check valves, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions: a kind of O-ring seal welding type check valve,
Including valve body, sliding sleeve skeleton is provided on the left of the inner cavity of the valve body, socket is provided with spring, the valve on the sliding sleeve skeleton
It is provided with the sliding sleeve seal head to match with sliding sleeve skeleton on the right side of the inner cavity of body, and is provided with O-ring on sliding sleeve seal head.
Preferably, the sliding sleeve seal head on be provided with the annular groove to match with O-ring, and on the inner wall of annular groove
It is provided with lateral anti-skid chequer.
Preferably, the O-ring is set as viton seal ring.
Preferably, convex block is provided on the left of the sliding sleeve seal head, and the width of convex block is less than the inner cavity of sliding sleeve skeleton
Width.
Compared with prior art, the utility model has the beneficial effects that
The O-ring seal welding type check valve, structure is simple, easy to use, negative-pressure sealing, can directly carry out welding soft close
Seal check valve and internal structure, and to the advantages such as welding process requirement is low.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model
In figure: 1 valve body, 2 sliding sleeve skeletons, 3 springs, 4 O-rings, 5 sliding sleeve seal heads.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of O-ring seal welding type check valve, including valve
Body 1, the inner cavity left side of valve body 1 are provided with sliding sleeve skeleton 2, and socket is provided with spring 3, the inner cavity right side of valve body 1 on sliding sleeve skeleton 2
It is provided with the sliding sleeve seal head 5 to match with sliding sleeve skeleton 2, and is provided with O-ring 4 on sliding sleeve seal head.
Wherein, sliding sleeve seal head 5 on be provided with the annular groove to match with O-ring 4, and be arranged on the inner wall of annular groove
There is lateral anti-skid chequer, can be fixed by O-ring 4 by annular groove and lateral anti-skid chequer, avoid O-ring 4 mobile；
O-ring 4 is set as viton seal ring, and viton seal ring long service life, installation is simple, can also even if deformation
It is installed；
The left side of sliding sleeve seal head 5 is provided with convex block, and the width of convex block is less than the lumen width of sliding sleeve skeleton 2, passes through
Convex block is installed convenient for the connection of sliding sleeve seal head 5 and sliding sleeve skeleton 2.
Working principle: the valve body 1 has structure simple, and negative-pressure sealing can be welded directly, and to welding process requirement
It is low.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
