Abstract
The invention discloses a valve body capable of stopping a valve clack from transversely moving. The valve body comprises a valve body (1) and a flange (2) connected to the valve body (1), and is characterized in that a groove (3) which can be matched with the lower end of a valve plate and prevents the valve plate from moving is formed in a boundary of the inner surface of the flange (2) and a channel of the valve body (1). Certain taper angles are formed in two sides of the channel of the valve body, displacement of the valve clack under high pressure is reduced, a sealing effect is improved, the quality of a product is guaranteed, and enterprise revenue is increased.
Description
Technical field
The present invention relates to valve, particularly a kind of valve body that stops the flap transverse shift.
Background technique
Valve is the controlling component in the fluid delivery system, has the functions such as cut-off, adjusting, water conservancy diversion, prevention adverse current, voltage stabilizing, shunting or overflow pressure relief.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Common valve channel is flat, and when valve is in high pressure conditions lower time, valve plate easily produces Side movement because there is pressure difference in the passage both sides, affects the sealing of valve.
Summary of the invention
Purpose of the present invention is exactly to solve the problem that affects valve seal because of the valve plate displacement.
The technical solution used in the present invention is a kind of valve body that stops the flap transverse shifting, it comprises valve body and is connected to flange on the valve body, offers the groove of a prevention valve plate displacement that can match with the valve plate lower end on the interface of flange internal surface and valve channel.
Wherein, described groove internal surface is arc surface.
Beneficial effect of the present invention is: by being provided with certain cone angle in the valve channel both sides, reduce flap displacement amount under high pressure, improve sealing effect, guarantee quality of product, increase the performance of enterprises.
Description of drawings
Fig. 1 is sectional view of the present invention;
Fig. 2 is the enlarged view of A part among Fig. 1;
Embodiment
Present embodiment as shown in Figure 1 and Figure 2, it comprises valve body 1 and is connected to flange 2 on the valve body 1, offers the groove 3 of a prevention valve plate displacement that can match with the valve plate lower end on the interface of flange 2 internal surfaces and valve body 1 passage.The internal surface of described groove is arc surface.Match with groove to stop and be subjected to displacement under hyperbaric environment in the valve plate lower end.
Claims (2)
1. valve body that can stop the flap transverse shift, it comprises valve body (1) and is connected to flange (2) on the valve body (1), it is characterized in that offering a groove that prevents the valve plate displacement (3) that can match with the valve plate lower end on the interface of flange (2) internal surface and valve body (1) passage.
2. a kind of valve body that stops the flap transverse shift according to claim 1, the internal surface that it is characterized in that described groove is arc surface.
