Abstract
The utility model relates to a ceramic valve ball type uniflow valve for controlling the unidirectional flow of liquid. The utility model is composed of a valve body, a valve seat and a valve ball, wherein the valve body is in a split type and is formed by the way that an upper joint and a lower joint are connected by screw threads. The ceramic valve seat and the valve ball are positioned in grooves in the joints on the lower part of the valve body and are fixed to the joints on the lower part of the valve body by a press cap in the way of helical extrusion. Liquid flow passages are uniformly arranged on the press cap. The utility model has the characteristics of reliable sealing, erosion resistance and abrasion resistance.
Description
The utility model relates to a kind of valve ball formula one-way valve that is used for the controlling liquid one-way flow.
The on-the-spot at present valve ball formula one-way valve sealability of using 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 its original one-way valve mostly is integrated type, because difficulty of processing institute extremely, valve seat and valve body supporting surface are prone to the gap, and 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, and Mi Feng reliability is lower for this reason; The sealing material erosion resistance antiwear property of valve ball, valve seat is poor, also be cause poorly sealed, one of reason of phenomenons such as leakage.
At problems such as above-mentioned valve ball formula one-way valve poor sealing performances, the utility model provides a kind of valve ball formula one-way valve of split type ceramic seal.
The utility model is achieved in that
Change the overall structure of former valve ball formula one-way valve into the branch body structure, valve body is made up of top sub (2) and bottom joint (9) scyewed joint, and this valve body structure has reduced the difficulty of processing and the quality of fit of valve body internal valve seat supports face.Ceramic valve seat (8) and ceramic valve ball (6) are located in the inner groovy of bottom joint (9) in the valve body, ceramic valve seat (8) is by pressure cap (3) and bottom joint (9) screw extrusion fixing seal, between being connected and fixed, ceramic valve seat (8) and pressure cap (3) be provided with gasket seal (7), at the connect interior edge face of top sub (2) with bottom joint (9), be provided with seal ring (5), thereby improved the reliability of valve body integral sealing.
There are shortcomings such as erosion resistance and abrasion resistance properties difference in the sealed material of the on-the-spot valve ball formula one-way valve that uses, has selected ceramic material valve seat (8) and valve ball (5) for this reason.Setting-in buffer rubber gasket sheet (4) in the groove of the interior top of pressure cap (3) has prevented the generation of phenomenons such as the frayed collision of valve ball (5) preferably.
The utility model is described in further detail below in conjunction with accompanying drawing and example:
Accompanying drawing (1) is a structural representation of the present utility model.
Number in the figure is represented: (1) sealing plug; (2) top sub; (3) pressure cap; (4) yielding rubber pad; (5) seal ring; (6) ceramic valve ball; (7) gasket seal; (8) ceramic valve seat; (9) bottom joint.
The utility model is described in further detail below in conjunction with accompanying drawing:
Ceramic valve ball formula one-way valve shown in Figure 1 is made up of valve body, valve seat and valve ball, valve body is made up of top sub (2) and bottom joint (9) scyewed joint, the interior edge face that connects of top sub (2) and bottom joint, be provided with seal ring (5), sealing plug (1) is located at the top of top sub (2), when the scene needs scavenging valve intracoelomic cavity foreign material, detachable lower seal plug (1).Pottery valve ball (6) is located in valve body lower portion joint (9) inner groovy, ceramic valve seat (8) is fixed by pressure cap (3) and the inboard screw extrusion of bottom joint (9), between ceramic valve seat (8) and pressure cap (3) are connected and fixed, be provided with gasket seal (7), yielding rubber pad (4) is housed in the groove of top in pressure cap (3), on pressure cap (3), evenly has the liquid flow channels.
Claims (4)
1, a kind of ceramic valve ball formula one-way valve, it is made up of valve body and valve seat and valve ball, it is characterized in that valve body is made up of top sub (2) and bottom joint (9) scyewed joint, ceramic valve seat (8) and ceramic valve ball (6) are located in the inner groovy of valve body lower portion joint (9), ceramic 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, ceramic valve ball formula one-way valve according to claim 1 is characterized in that being provided with gasket seal (7) between being connected and fixed of ceramic valve seat (8) and pressure cap (3).
3, ceramic valve ball formula one-way valve according to claim 1 is characterized in that in the groove of the interior top of pressure cap (3) setting-in yielding rubber pad (4).
4, ceramic valve ball formula one-way valve according to claim 1 is characterized in that being provided with seal ring (5) at the interior edge face that connects of top sub (2) with bottom joint (9).
