Abstract

The utility model discloses a two-piece type plastic ball valve which is composed of a valve body, a ball core, a valve rod, a handle, a plastic pad, etc., wherein, the valve body is composed of a body and a valve cover; a rubber elastomer gasket is arranged between the valve body and the plastic pad, and another rubber elastomer gasket is arranged between the valve cover and the plastic pad, the elastomer can play compensating action when the valve body deforms for the change of climate and temperature or the work pressure of pipelines. Meanwhile, the pressing force between the body and the valve cover is transferred between the plastic pad and the sphere through the rubber elastomer, so that the sealing effect between the sphere and the plastic pad can be achieved.

Description

The two-piece type ball valve made of plastic
The utility model relates to a kind of water supply ball valve.
Along with the high speed development of science and technology and human raising to self health, environmental consciousness, be widely used in the water system of civil engineering at some scientific and technological developed country non-toxic engineering plastic pipes, progressively replace the galvanized iron conduit that gets rusty easily.But the valve in the water system is metal valve still, thereby needs to use two special joints to be connected cost height, and constructional difficulties between plastic tube and metal valve.At present, have a kind of integrated type Plastic valve cost lower, but this Plastic valve is easy to wear, and sealing is poor, thereby use is restricted.
The purpose of this utility model is to overcome the deficiencies in the prior art, and the novel plastic valve of a kind of excellent wear resistance, sealing is provided.
The purpose of this utility model is to realize like this, design a kind of ball valve of two chip architectures, form by valve body, ball core, valve rod, handle, plastics king pad etc., valve body is made up of main body and valve gap two-part, and between valve body and the plastics king pad, between valve gap and the plastics king pad, be provided with the rubber elastomer packing ring.
Body described in the utility model and valve gap are equipped with groove, in the elastomer packing ring mosaic groove.
Body described in the utility model or valve gap end can be provided with internal thread.
Body described in the utility model or valve gap end can be provided with outside thread.
The utility model is made up of valve body, ball core, valve rod, handle, plastics king pad etc., valve body is made up of main body and valve gap two-part, and between valve body and the plastics king pad, between valve gap and the plastics king pad, be provided with the rubber elastomer packing ring.This elastomer can play compensating action to valve body when weather, temperature or pipeline change of pressure cause distortion; Simultaneously, when ball valve production was assembled, the impacting force between main body and the valve gap, made can arrive sealing effect between spheroid and the plastics king pad between plastics king pad and the spheroid by the rubber elastomer transfer function, leakage phenomenon can not take place.
Reaching embodiment in conjunction with the accompanying drawings is further described the utility model:
Accompanying drawing 1, the utility model example structure schematic representation;
As shown in Figure 1, the ball valve made of plastic body is made up of main body (9) and valve gap (6) for the two-piece type structure, between main body (9) and the plastics king pad (8), between valve gap (6) and the plastics king pad (8), be provided with rubber elastomer packing ring (7), two elastic body shims (7) are embedded in respectively in main body (9) and the plastics king pad (8); Metal Ball core (10) is arranged between the two plastics king pads (8), and Metal Ball core (10) is inserted by main body (9) in the bottom of valve rod (1); Handle (4) is enclosed within on the valve rod (1), and fixes by pad (3), handle nut (2); O RunddichtringO (5) also is housed on valve rod (1).

Claims (4)
