Abstract
The invention provides a novel butterfly valve. The novel butterfly valve comprises a valve body, a main butterfly plate, a secondary butterfly plate, a valve rod, a main handle and a secondary handle, wherein the main butterfly plate and the secondary butterfly plate are arranged in the valve body, and are vertically arranged; the main butterfly plate is connected with the main handle through the valve rod; the secondary butterfly plate consists of a first sub butterfly plate and a second sub butterfly plate; the first sub butterfly plate is connected with the secondary handle through a sub valve rod; and the second sub butterfly plate consists of multiple blades. When the butterfly valve is closed, the main butterfly plate is located in a closing state; after the main butterfly plate rotates by 90 degrees, the butterfly valve is opened; the secondary butterfly plate is located in a working state; the second sub butterfly plate in the secondary butterfly plate is designed as multiple blades, so that a medium is more stable in circulation; the first sub butterfly plate is adjusted through the secondary handle to control the magnitude of flow of the butterfly valve; and a buffer belt arranged at one side of the opening direction of the valve body can prevent the impact of the main butterfly plate to the secondary butterfly plate in opening.
Description
Technical field
The invention belongs to valve field, especially relate to a kind of novel butterfly valve.
Background technique
At present, butterfly valve is widely used in the industries such as chemical industry, food, water, electricity, mainly plays Flow-rate adjustment and the cut-off effect of flowing medium.Existing butterfly valve structure is made up of valve body, butterfly plate and valve rod, this butterfly valve comes by the opening and closing of a butterfly plate that control media flows in butterfly valve, therefore it can not carry out the flow of regulating butterfly valve medium according to the service condition of user, there is awkward problem.
Summary of the invention
In view of this, the present invention is intended to propose that a kind of structure is simple, the butterfly valve of use safety, can regulate the flow in butterfly valve.
For achieving the above object, technological scheme of the present invention is achieved in that
A kind of novel butterfly valve, comprise valve body, main butterfly plate, secondary butterfly plate, valve rod, main handle and auxiliary-handle, described valve interior wall is provided with seal ring, described main butterfly plate is provided with in described valve body, described main butterfly plate is provided with described secondary butterfly plate, described main butterfly plate is vertical with secondary butterfly plate to be arranged, described main butterfly plate is connected with described main handle by described valve rod, described secondary butterfly plate is made up of the first sub-butterfly plate and the second sub-butterfly plate, described first sub-butterfly plate is connected with auxiliary-handle by sub-valve rod, the size of butterfly valve flow can be controlled by rotating the first sub-butterfly plate, described second sub-butterfly plate is made up of several blinds, second sub-butterfly plate is designed to some blinds can make medium circulate more stable, all anti-corrosion layer is scribbled on the surface of described main butterfly plate and secondary butterfly plate.
Further, be provided with the buffer strip of rail shape in the side of described valve body opening direction, the impact to secondary butterfly plate when avoiding main butterfly plate to open.
Further, described valve rod and described main butterfly plate are cast as one, and prevent valve rod and main butterfly plate from occurring loosening or rupturing, strengthen the working life of butterfly valve.
Further, described seal ring is vulcanized rubber seal ring.
Further, described anti-corrosion layer is polyurethane elastomer.
Relative to prior art, butterfly valve of the present invention has following advantage: when butterfly valve cuts out, main butterfly plate is in closed condition, after main butterfly plate 90-degree rotation, butterfly valve is opened, secondary butterfly plate is in running order, sub-in secondary butterfly plate second butterfly plate is designed to some blinds can make medium circulate more stable, regulate the first sub-butterfly plate can control the size of butterfly valve flow by auxiliary-handle, the impact to secondary butterfly plate when the buffer strip arranged in the side of valve body opening direction can avoid main butterfly plate to open; There is the advantages such as structure is simple, diverse in function, use safety, butterfly valve long service life.
