Combined type stop valve

Abstract

The invention discloses a combined type stop valve. The combined type stop valve comprises a valve body, a pressing cap and a depressurizing screw. The upper end of the valve body is provided with aninstallation hole for installing the pressing cap. One side in the transverse direction of the valve body is provided with a liquid inlet hole, the transverse side face, opposite to the liquid inlet hole, of the valve body is provided with a side face liquid outlet hole, and the bottom end of the valve body is provided with a bottom liquid outlet hole. The pressing cap is internally provided witha stop assembly. The depressurizing screw comprises a screwing end, the upper end of the screwing end is provided with a connecting double-screw bolt, the upper end of the connecting double-screw boltis provided with a blocking column, and the depressurizing screw is internally provided with a depressurizing channel used for reducing pressure. The combined type stop valve has the beneficial effects that by means of the depressurizing screw, opening and blocking of the side face liquid outlet hole and the bottom liquid outlet hole are achieved, switching between a straight-through manner and astraight-angle manner of the device can be achieved, different using requirements can be met, and the application range is wide; and the depressurizing double-screw bolt is screwed, the depressurizing effect can be achieved through the depressurizing channel, and the device is diverse in function and good in using effect.

Description

Technical field [0001] The present invention relates to the technical field of stop valves, in particular to a composite stop valve. Background technique [0002] The stop valve, also called the cut-off valve, is one of the most widely used valves. The reason why it is popular is that the friction between the sealing surfaces during opening and closing is small, it is relatively durable, the opening height is not large, and it is easy to manufacture , Easy maintenance, not only suitable for medium and low pressure, but also suitable for high pressure. Right-angle globe valves and straight-through globe valves are two commonly used globe valves, which are used in different occasions according to specific pipeline distribution and requirements, such as Figure 7 Is the front view of the internal structure of the right-angle globe valve, such as Figure 8 It is the front view of the internal structure of the straight-through globe valve. The current globe valve cannot realize the con...

Problems solved by technology

[0003] The purpose of the present invention is to provide a composite shut-off valve in order to solve the above problems, so as to solve the problem that the current shut-off valve in the prior art cannot realize the conversion between the right-angle type and the straight-through type, and cannot meet different use requirements. Restricted; at the same time, it does not have the pressure relief function, the use effect is not ideal and other technical problems
