Abstract
The utility model relates to a piston type shunt valve which comprises a valve body 4, an inlet 3, an outlet 1, an outlet 2, a piston rod 5, sealing rings 6, 7 and a handle 8. The handle pushes the piston rod to move at the inner cavity of the valve body. The sealing rings 6, 7 divide the inner cavity of the valve body into three spaces which are not mutually communicated, and thereby, a passage where the fluid flows is controlled. The utility model has the advantages of simple structure, easy fabrication, low cost and long service life, and can be used for the passage for controlling gas and liquid. The component parts are not easy to wear.
Description
The utility model belongs to valve technology field.
Common valve seals pipeline with rubber ring, ball, thus the circulation of control fluid.Rubber parts in this valve is wearing and tearing easily in use, cause the leakage current body, and promote the also damage easily of screw rod of rubber parts.
The purpose of this utility model is to provide a kind of fluid valve that adopts piston rod and seal ring control fluid passage.
The utility model comprises outlet 1, outlet 2, import 3, valve body 4, piston rod 5, seal ring 6,7, handle 8.
Fig. 1 is a structural drawing of the present utility model.
Below, as follows to structure of the present utility model and connection description in conjunction with Fig. 1. At valve On the body 4, import 3, outlet 1 are arranged and export 2. Piston rod 5 is contained in the chamber of valve body 4 In, can unhinderedly motion in the chamber. The left end dress sealing ring 6 and close of piston rod 5 Seal 7, sealing ring 6,7 and valve body 4 inner chambers combine closely, seal, and Valve body 4 inner chambers are separated into three mutual disconnected spaces. Handle 8 is contained in piston rod 5 Right-hand member. Right section of piston rod 5 and right section of valve body 4 inner chambers also can be made screw thread, And with the screw thread combination, make piston rod 5 can advance while rotating, retreat in that valve body 4 is interior.
The utility model has five kinds of duties:
A. piston rod 5 is at high order end, and promptly seal ring 6 is positioned at valve body 4 inner chamber high order ends, and seal ring 7 is positioned at outlet 2 leftward position, and valve is a cut-off state.
The utility model also can be provided with a plurality of outlets and reach and the corresponding a plurality of seal rings of its quantity, can control many runners simultaneously.
The utility model can be used for controlling liquid pipeline and gas pipeline, and its advantage is simple in structure, easily processing, and easy to use, cost is low, and long service life is not fragile.
