Description
Technical field
A kind of check-valves is the utility model is related to, specifically a kind of T-shaped check-valves.
Background technology
Check-valves be in daily life and industrial production in common component, in the prior art check-valves be typically all include
Straight-through valve body, the retaining element structure such as the interior sliding sleeve set of valve body and spring, in use, being realized by retaining element prevents
The function that medium is flow backwards, but existing check-valves is usually required for a valve and a curved logical or threeway in use
Combination is completed, and thus, on the one hand so that connector is relatively more, sealing reliability reduces, and easily there is the risk leaked, and in addition one
Aspect, two products can produce many clouts in process of production, cause the waste of production cost, another further aspect, its structure sheet
The limitation of body, not only complex process, and volume is larger, occupies larger space.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of sealing reliability it is good, occupy little space and production cost
Low T-shaped check-valves.
In order to solve the above-mentioned technical problem, the T-shaped check-valves of the utility model, including longitudinal tube body and be vertically set on it is vertical
Horizontal tube body in the middle part of to tube body, longitudinal tube body and transverse pipe body by integral forming form whole T-valve body, the center of longitudinal tube body
With longitudinal runner through its length direction, the center of horizontal tube body has the horizontal stroke with the perforation of longitudinal runner along its length
To runner, the openend of horizontal tube body is provided with non-return component placement chamber, the non-return component placement intracavitary be provided with sliding sleeve with
And spring, sliding sleeve have the spring placing chamber for being used for disposing spring, spring is placed in spring placing chamber and non-return component placement chamber
Bottom between, the openend of horizontal tube body is additionally provided with the bonnet for closing non-return component placement chamber.
The excircle of the transverse direction tube body is provided with external screw thread, and internal thread is provided with the inner periphery of the bonnet, described
Bonnet is connected with horizontal tube body by internal and external threads.
The annular groove of male ends root is provided with the transverse direction tube body, is mounted with the annular groove for sealed bonnet
With the exterior O-ring seals of horizontal tube body.
Internal shape sealing ring is provided between the open end of the inner cavity root of the bonnet and horizontal tube body.
After above-mentioned structure, due to whole T-valve body by integral forming and check-valves placing chamber is arranged on transverse pipe
The openend of body, so that the functional unit such as check valve assembly is entirely located in the openend of horizontal tube body, it is thus on the one hand, whole
Body formed structure no longer needs to connect multiple connectors, avoids the risk of leakage, substantially increases the reliability used, in addition
On the one hand, overall processing shaping saves material, avoids the waste of production cost, another further aspect, its scientific structure design is closed
Reason, technique is simple, reduces manufacturing process and compact-sized, easy for installation, saves space, expand application range.
