Description

Bidirectional metal hard seal manual welding butterfly valve

Technical Field

The utility model relates to the technical field of butterfly valves, in particular to a bidirectional metal hard seal manual welding butterfly valve.

Background

A butterfly valve, also called a flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline media, namely a valve which is opened and closed by rotating around a valve shaft, wherein a closing member (a valve clack or a butterfly plate) is a disk. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The pipe mainly plays a role in cutting off and throttling. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved. Because most of water is not completely purified, impurities exist in the water, and the impurities can block a valve of a pipeline to influence the flow of the water in the long-term past, the butterfly valve needs to be cleaned regularly, but the butterfly valve is very troublesome to clean, and therefore a bidirectional metal hard sealing manual welding butterfly valve is provided.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, a bidirectional metal hard seal manual welding butterfly valve comprises a butterfly valve body 1, a connecting pipe 2 is welded at the right end of the butterfly valve body 1, and a filter structure 3 is arranged in the connecting pipe 2;

the impurities in the liquid passing through the butterfly valve body 1 can be filtered through the arranged filtering structure 3.

The filter structure 3 comprises a placing groove 31 arranged at the inner ring of the connecting pipe 2, a filter screen 32 is arranged in the placing groove 31 in a left-right sliding mode, pull rods 33 are arranged at the upper end and the lower end of the right side wall surface of the filter screen 32, and pull rings 34 are arranged at the ends, far away from the filter screen 32, of the pull rods 33.

Can filter the impurity in the liquid through filter screen 32, when filter screen 32 blockked up, pulling pull ring 34 to through pull rod 33 pulling filter screen 32, take out filter screen 32 and clear up, avoid influencing rivers and flow through.

Specifically, the buffer structure 4 is provided between the pair of tie rods 33.

Can cushion rivers through buffer structure 4, reduce the rivers impact force, protect filter screen 32 and butterfly valve body 1.
