Description

Novel butterfly valve

Technical Field

The utility model relates to a butterfly valve technical field specifically is a novel butterfly valve.

Background

A butterfly valve, also called a flap valve, is a regulating valve with a simple structure, can be used for on-off control of low-pressure pipeline media, and is a valve, the closing part of which is a disk and rotates around a valve shaft to open and close, and 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.

The lower end cover to wearing traditional butterfly valve all installs through the round pin post, but along with live time's lapse, the phenomenon of ageing appears easily in the mounting hole of its round pin post and round pin post looks adaptation, drops easily at the during operation, leads to dropping of lower end cover, for this reason the utility model provides a novel butterfly valve.

Disclosure of Invention

An object of the utility model is to provide a novel butterfly valve to solve the problem that proposes among the above-mentioned background art.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a novel butterfly valve, including valve body and valve rod, the valve plate is installed to one side of valve rod, through the round pin columnar connection between valve plate and the valve rod, the bottom end cover is installed through the screw thread post in the bottom of valve body, the ring channel has been seted up to the bottom of valve body surface, the equal fixedly connected with installation plug-in components in the left and right sides of ring channel internal surface, the inside fixedly connected with diaphragm of installation plug-in components, the inside of diaphragm is connected screw thread post and diaphragm through the spacer pin.

As an optimal technical solution of the utility model: the bottom end of the valve rod is provided with a thrust key, and the lower end cover is provided with a thrust gasket.

As an optimal technical solution of the utility model: and a packing cover is arranged above the valve body through a hexagon nut.

As an optimal technical solution of the utility model: and a compression ring is arranged on one side of the valve plate through a hexagon screw.

As an optimal technical solution of the utility model: install down cun cover between the internal surface of valve body and the bottom of valve rod surface, install last cun cover between the upper end of the internal surface of valve body and valve rod surface.

As an optimal technical solution of the utility model: and a packing cylinder is arranged below the packing cover.

The utility model discloses the beneficial effect who reaches is: the utility model discloses a cooperation between ring channel, installation plug-in components and the spacer pin can realize spacing to the screw thread post, can avoid appearing the condition that drops because of the screw thread post is ageing, can be more firm to the lower end cover installation.
