Abstract
The utility model discloses a kind of check valves, including sequentially connected take over one, internal valve seat and take over two, the take over one with spool to be connect with valve seat equipped with take over expansion mouth.Top baffle ring is equipped between piston in the take over expansion mouth and valve seat of the take over one.Pad there are one being set between the take over expansion mouth and the valve seat.The utility model has the beneficial effects that：Flaring is carried out by butt tube one and changes angle, keeps runner variation gentle, identical bore product increases flow；Cancel valve deck component, to reduce by a solder joint, reduces welding difficulty, reduce risk of leakage；Reduce production cost.
Description
Technical field
The utility model is related to a kind of check valves.
Background technology
Check valve is a kind of valve member for making fluid only be flowed to direction and it can be prevented to flow round about, can be with
It is widely used in air-liquid circuit or cooling cycle system, to refer to fluid countercurrent current.Check valve, which generally comprises, is set to valve body
The indoor spool of chamber, when reverse flow occurs for fluid, spool can block channel to prevent reverse fluid flow.Such as Fig. 1 institutes
Show, existing check valve generally comprises valve deck 1, valve deck take over 2, valve seat 3, valve seat take over 4, and guide post 5, piston are provided in valve seat 3
6, spring 7, top baffle ring 8, diaphragm 9, tabletting 10 are equipped with top baffle ring 8 between the piston 6 in valve deck 1 and valve seat 3.Valve deck with
Valve deck is taken over equipped with pad a, and valve deck and valve seat are equipped with pad and b.Due to the valve deck and valve body solder joint of this structure one-way valve
It is closer apart from valve deck and take over solder joint, it is welded with larger difficulty, bad rate is higher for solder joint leakage.Existing structure valve deck component have compared with
Big flow resistance influences the flow of entire product.
Invention content
The technical problem to be solved by the utility model is to provide one kind carrying out flaring alternative valve cover by butt tube 1
To reduce the check valve of pad.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of check valve, including connect successively
Take over one, the internal valve seat for carrying spool and take over two, the take over one connect connect equipped with take over expansion mouth with valve seat.
Top baffle ring is equipped between piston in the take over expansion mouth and valve seat of the take over one.
Pad there are one being set between the take over expansion mouth and the valve seat.
It is provided with guide post in the valve seat, piston is provided in the guide post.
Diaphragm is equipped between guide post end and valve seat.
Tabletting is equipped between the piston and take over two.
The utility model has the beneficial effects that：Flaring is carried out by butt tube one and changes angle, keeps runner variation gentle, phase
Increase flow with bore product；Cancel valve deck component, to reduce by a solder joint, reduces welding difficulty, reduce risk of leakage；Drop
Low product cost of manufacture.

Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in Fig. 2, a kind of check valve, including sequentially connected take over one, internal valve seat and take over two with spool,
Take over 1 connect equipped with take over expansion mouth 200 with valve seat 300, in the take over expansion mouth 200 and valve seat 300 of take over 1
It is equipped with top baffle ring 600 between piston 500, is set between take over expansion mouth 200 and the valve seat there are one pad c.By right
Take over 1 carries out flaring design and forms take over expansion mouth 200, one 100 and the welding of valve seat 300 is directly will take over, to fixed
Top baffle ring 600, only one pad c.The flaring angle of take over 1 keeps runner variation gentle, and identical bore product increases
Flow.
