Abstract
The utility model discloses a dan youling check valve, including valve body and case, the case is installed in the valve body, and the case is used for the part of sealed inlet to be the cone. The utility model discloses simple to operate is swift, and a case can with the valve body phase -match of multiple specification.
Description
Technical field
This utility model relates to check-valves technical field, particularly to a kind of Dan Youling check-valves.
Background technology
Check-valves refers to rely on medium itself to flow and automatic open and close flap, is used for the valve preventing medium from flowing backwards, also known as check valve.Check-valves belongs to a kind of automatic valve, and its Main Function is to prevent medium from flowing backwards, prevent pump and drive motor reversion, and the leakage of vessel media.
Dan Youling check-valves belongs to the one of check-valves.The spool of the most common Dan Youling check-valves mostly is hemisphere or whole ball-type, when this spool is installed, need to withstand on valve body with hands or other instruments by spool, then Fast Installation nut, otherwise, spool is susceptible to or drops, and causes Dan Youling check-valves installation difficulty, and this spool is when containing fine impurity in media as well, the most easily block.
In consideration of it, the present inventor develops a kind of new Dan Youling check-valves for this, effectively solving the problems referred to above, this case thus produces.
Utility model content
A kind of Dan Youling check-valves that this utility model provides, quick and easy for installation, and a kind of spool can match with the valve body of plurality of specifications.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of Dan Youling check-valves, including valve body and spool, spool is installed in valve body, and spool is cone for sealing the part of inlet.
Described cone is the conical shell of bottom-open.
Described spool forms cylindrical shell in the bottom of cone, and cylindrical shell one end connects with cone, and the other end opens wide.
The breach passed through for liquid is offered in the side of described cylindrical shell.
Described breach has 3.
Also including that coupling nut and pipe connect, pipe was connected coupling nut and was fixedly mounted on valve body, and pipe connects the end of nearly valve body as inlet, and end is provided with the O for sealing, and cone is pressed on O and plays the sealing function preventing adverse current.
Described pipe connects and is provided with the seal washer preventing from leaking between valve body.
Described Dan Youling check-valves is PVC Dan Youling check-valves.
After using such scheme, this utility model is cone due to the sealing position of spool, and the most when mounted, spool can stand on inlet smoothly, it is not necessary to using hands or other instrument to head on spool, the installation making Dan Youling check-valves is simpler convenient.Simultaneously because the sealing of spool is taper, its diameter from tip to bottom persistently increases, as long as the diameter of valve body and inlet is within the specific limits, the most all can use, the spool of a kind of specification can be used on the valve body of plurality of specifications, in emergency circumstances, can temporarily instead of using.

Label declaration
Valve body 1, spool 2, cone 21, cylindrical shell 22, breach 23, coupling nut 3, pipe connects 4, seal washer 5, inlet 6, O 7.
Detailed description of the invention
In order to the technical solution of the utility model is explained further, below by specific embodiment, the utility model is elaborated.
As Figure 1-3, being the Dan Youling check-valves be made up of PVC material of a kind of main body that discloses of this utility model, it includes valve body 1 and spool 2, and spool 2 is installed in valve body 1.Also including that coupling nut 3 and pipe connect 4, pipe is connect 4 and is fixedly mounted on valve body 1 by coupling nut 3, and pipe connects and is provided with the seal washer 5 preventing from leaking between 4 and valve body 1.Pipe connects 4 near the end of valve body 1 as inlet 6, and end is provided with the O 7 for sealing, and spool 2 is pressed on O 7 and plays the sealing function preventing adverse current.
Wherein spool 2 is cone 21 for sealing the part of inlet 6, and this cone 21 is the conical shell of bottom-open, when liquid countercurrent, the inside of hydraulic shock cone 21, cone 21 is hit the effect of power, can be firmly by Dan Youling closure of check ring, and job stability is the best.
As shown in Figure 4, spool 2 forms cylindrical shell 22 in the bottom of cone 21, and cylindrical shell 22 one end connects with cone 21, and the other end opens wide.Three breach 23 passed through for liquid are offered in the side of cylindrical shell 22.During following current, after liquid pushes spool 2 open, flow out at this breach 23.Shown in Fig. 1, this breach 23 also solves when being in following current state for a long time, the little granule foreign contained in fluid will pile up the problem that result in blockage in the junction of spool 2 and valve body 1, and breach 23 makes little granule foreign can flow directly out at breach 23, play anti-blocking must act on.
The present embodiment is cone 21 due to the sealing position of spool 2, and the most when mounted, spool 2 can stand on inlet 6 smoothly, will not run-off the straight, it is not necessary to using hands or other instrument to head on spool 2, the installation making only Dan Youling check-valves is simpler convenient.When needs clean, open coupling nut 3, the parts such as spool 2, seal washer 5 and O 7 are taken out and cleans.
Simultaneously because the sealing of spool 2 is taper, its diameter from tip to bottom persistently increases, as long as the diameter of valve body 1 and inlet 6 is within the specific limits, the most all can use, the spool 2 of a kind of specification can be used on the valve body 1 of plurality of specifications, in emergency circumstances, can temporarily instead of using.
These are only preferred embodiment of the present utility model, the not restriction to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, each fall within the protection domain of this case.
