Abstract
The utility model relates to a polytetrafluoroethylene valve core type check valve which is a check valve for controlling the unidirectional flow of liquid. The utility model is composed of a valve body, a polytetrafluoroethylene valve seat and a polytetrafluoroethylene valve core, wherein the valve body is split and is formed by connecting an upper joint and a lower joint by screw threads; the valve seat and a valve core seat are positioned in a groove in a joint of on lower part of the valve body; the valve seat is fixed by the screw extrusion of a press cap and the joint of the lower part; a control spring is installed on the upper end of the valve core; fluid flow passages are evenly formed on a press cap body. The utility model has the characteristics of reliable sealing and corrosion resistance.
Description
The utility model relates to a kind of teflon valve core type one-way valve that is used for the controlling liquid one-way flow.
What on-the-spot at present use was more is valve ball formula one-way valve, its sealability is relatively poor, phenomenon such as often occur being not closed completely, its main cause is that the structural design of one-way valve is unreasonable, the valve body of former one-way valve mostly is integrated type, because difficulty of processing institute extremely, the single-stage that the sealing of valve seat and valve body supporting surface only depends on pressure cap extruding valve seat to form valve seat seals firmly.For this reason, the reliability of sealing is lower; The erosion resistance wear resistance of valve seat, valve ball Manufacturing material is poor, also is one of reason that causes phenomenons such as one-way valve is poorly sealed, leakage.
At problems such as above-mentioned valve ball formula one-way valve poor sealing performances, the utility model provides a kind of teflon valve core type one-way valve.
The utility model is achieved in that
Change into former integrated type one-way valve split type, valve body is made up of top sub (2) and bottom joint (9) scyewed joint, this valve body structure, reduced in the processing valve body and the difficulty of valve seat supporting surface, teflon valve seat (8) and teflon spool (5) are located in interior bottom joint (9) groove of valve body, teflon valve seat (8) is by pressure cap (3) and the inboard screw extrusion fixing seal of bottom joint (9), thereby improved the quality of fit of supporting surface and valve seat, having changed in the past, single-stage seals firmly, formed the twin-stage sealing of thread seal, improved the reliability of valve seat and supporting surface sealing with hard sealing.
The sealed material existence of the on-the-spot valve ball formula one-way valve that uses is easily got rusty, shortcomings such as anti-erosion and abrasion resistance properties difference, and the utility model has selected polytetrafluoroethylmaterial material to make valve seat and spool for this reason.Teflon valve seat (8) is taper with the surface of contact of teflon spool (5).Connect interior edge face at top sub (2) with bottom joint (9), be provided with seal ring (6).Teflon valve seat (5) is set in the pressure cap (3), and the top of teflon spool (5) is provided with control spring (4).Pressure cap evenly has the liquid flow channels on (3).
The utility model is described in further detail below in conjunction with accompanying drawing and example:
Accompanying drawing 1 is the structural representation of teflon valve core type one-way valve:
Number in the figure is represented: (1) sealing plug; (2) top sub; (3) pressure cap; (4) control spring; (5) teflon spool; (6) seal ring; (7) gasket seal; (8) teflon valve seat; (9) bottom joint.
The utility model is described in further detail below in conjunction with accompanying drawing:
The described teflon valve core type of Fig. 1 one-way valve is made up of valve body, valve seat and spool.Valve body is split type, is made up of top sub (2) and bottom joint (9) scyewed joint, and seal plug (1) is located at the top of top sub (2), and when the scene needed scavenging valve intracoelomic cavity foreign material, detachable lower seal plug (1) was operated.The interior edge face that connects of top sub (2) and bottom joint (9), be provided with seal ring (6), teflon valve seat (8) and teflon spool (5) are located in the inner groovy of valve body lower portion joint (9), teflon valve seat (8) is fixed by the pressure cap (3) and the inboard screw extrusion of bottom joint (9), between being connected and fixed, teflon valve seat (8) and pressure cap (3) be provided with gasket seal (7), teflon spool (5) is set in the pressure cap (3), and the top of teflon spool (5) is provided with control spring (4).
Claims (4)
1, a kind of teflon valve core type one-way valve, it is made up of valve body and valve seat spool, it is characterized in that valve body is made up of top sub (2) and bottom joint (9) scyewed joint, teflon valve seat (8) is taper with the surface of contact of polytetrafluoroethyl-ne spool (5), teflon valve seat (8) and teflon spool (5) are located in bottom joint (9) inner groovy, teflon valve seat (8) is fixed by pressure cap (3) and bottom joint (9) screw extrusion, and pressure cap evenly has the liquid flow channels on (3).
2, teflon valve core type one-way valve according to claim 1, it is characterized in that being connected and fixed at teflon valve seat (8) and pressure cap (3) is provided with gasket seal (7) between the end face.
3, teflon valve core type one-way valve according to claim 1 is characterized in that in teflon spool (5) was set in pressure cap (3), the top of teflon spool (5) was provided with spring (4).
4, teflon valve core type one-way valve according to claim 1 is characterized in that being provided with seal ring (6) at top sub (2) with the interior edge face that connects of bottom joint (9).
