Abstract

An angle-form stop valve comprises a valve body, a valve deck and a valve rod and is characterized in that a rectangular angle is formed between the axis of a water inlet passageway of the valve bodyand the axis of a water outlet passageway of the valve body. The problem that a present through stop valve cannot be connected with a pipeline in a right-angle manner is solved, and the angle-form stop valve is suitable for flow control of liquid and gas.

Description

Technical field: [0001] The invention relates to the field of flow control of fluid pipelines, in particular to a flow control valve for liquid and gas. Background technique: [0002] At present, most of the cut-off valves designed and produced in the society adopt the straight-through form, and the disadvantage is that they cannot be installed on vertically intersecting pipelines. Invention content: [0003] In order to solve the problem that straight-through valves cannot be installed on vertically intersecting pipelines, the present invention invents a valve that can be installed on vertically intersecting pipelines. [0004] The technical solution of the present invention is an angle-shaped globe valve, which includes a valve body, a valve cover, and a valve stem. [0005] The valve body is equipped with a disc matching the sealing surface, the valve body is connected with the bonnet bolts, the valve stem is installed in the middle of the bonnet, the lower end of the ...
