Description

Stop valve body

Technical Field

The utility model relates to the technical field of stop valves, in particular to a stop valve body.

Background

Stop valves generally comprise a valve body and a shutter (flap) that moves linearly along the valve body. The valve is very suitable for flow regulation because of the relatively short opening or closing stroke and very reliable shut-off function.

Currently, existing shut-off valve bodies mainly include T-shaped, angled, and Y-shaped valve bodies. Both the internal structure and the external shape of these types of shut-off valve bodies are relatively complex. For example, a shut-off valve body is shown in fig. 1, which includes a bonnet mounting hole 3' opened at the top surface, and an input hole 1' opened at the left side surface and an output hole 2' opened at the right side surface. The hole bottom area of the input hole 1' is arc-shaped and is communicated with the hole bottom of the valve cover mounting hole 3', the valve cover is mounted on the valve cover mounting hole 3', the valve rod penetrates through the valve cover and stretches into the valve cover mounting hole 3', the opening and closing piece (valve clack) at the bottom of the valve rod is blocked at the hole bottom of the input hole 1', and the output hole 2' is arc-shaped and is communicated with the valve cover mounting hole 3 '. The flow is controlled by controlling the blocking degree of the opening and closing piece (valve clack) to the bottom of the input hole 1' through the linear movement of the valve rod. However, the arcuate holes in the interior of such shut-off valve bodies cannot be machined directly, and it is often necessary to manufacture the valve bodies by casting. This results in high production costs, and low cast external surface finish, and also low precision of the shut-off valve.

Disclosure of utility model

Therefore, the utility model provides the stop valve body, which mainly solves the technical problems of high production cost and low precision caused by the fact that the stop valve body in the prior art is manufactured in a casting mode.

In order to achieve the above object, the present utility model provides the following technical solutions:

A stop valve body comprises a valve cover mounting hole, an input hole and an output hole, wherein the valve cover mounting hole is formed in the top surface of the stop valve body, the input hole is formed in the left side surface of the stop valve body, and the output hole is formed in the right side surface of the stop valve body; the bottom surface of the valve cover mounting hole is provided with a plugging hole; the valve cover mounting hole is used for mounting a valve cover; the blocking hole is used for placing a valve clack arranged at the bottom of the valve rod; the aperture of the valve cover mounting hole is larger than that of the blocking hole; the input hole is positioned below the blocking hole; the input hole is communicated with the valve cover mounting hole through the blocking hole; the output hole is communicated with the valve cover mounting hole.

Preferably, the input Kong Kongxiang and the output aperture are aligned in a direction perpendicular to the valve cover mounting aperture or the plug aperture; the output channel is arranged along the hole direction of the valve cover mounting hole.
