Abstract
The invention provides a butterfly valve. The butterfly valve comprises a valve body. A first valve element and a second valve element are arranged in the valve body. The first valve element comprises a first moving valve element body and a first fixed valve element body. The second valve element comprises a second moving valve element body and a second fixed valve element body. The first fixed valve element body and the second fixed valve element body are both fixed into the valve body. The first moving valve element body is connected with a first valve rod. The second moving valve element body is connected with a second valve rod. The first valve rod and the second valve rod both penetrate through the valve body. The first valve rod is parallel to the second valve rod. The first moving valve element body is parallel to the second moving valve element body. The top end of the first valve rod and the top end of the second valve rod are both fixedly connected with a cross rod. The cross rod can drive the first moving valve element body to get close to or keep away from the first fixed valve element body relatively and can synchronously drive the second moving valve element body to get close to or keep away from the second fixed valve element body relatively. Through the arrangement of the two moving valve element bodies, the interception effect of the butterfly valve can be improved. Even if one valve element breaks down, continuous use of the butterfly valve is not affected, the replacing frequency of the butterfly valve can be reduced, and the service life of the butterfly valve is prolonged.
Description
Technical field
The invention belongs to flow-control field, especially relate to a kind of butterfly valve.
Background technology
Valve is the machinery controlling the flow of fluid media (medium) of flowing, the flow direction, pressure, temperature etc., and valve is parts basic in tubing.Existing valve, very serious due to what use certain time back valve core to be often worn, and general valve often can only be acidproof or alkaline-resisting, when after the valve selecting resistance to acids and bases mistake, service life is very short, that had both wasted workman changes the time of unloading, and wastes again material.
Summary of the invention
The problem to be solved in the present invention is to provide the butterfly valve of a kind of time in service life length.
nullFor solving above-mentioned technical problem，The technical solution used in the present invention is: a kind of butterfly valve，Including valve body (1)，The first spool and the second spool it is provided with in described valve body (1)，Described first spool includes the first movable valve plug (4) and the first fixed valve plug，Described second spool includes the second movable valve plug (2) and the second fixed valve plug (7)，Described first fixed valve plug and described second fixed valve plug (7) are each attached in described valve body (1)，Described first movable valve plug (4) is connected with the first valve rod (5)，Described second movable valve plug (2) is connected with the second valve rod (3)，Described first valve rod (5) and described second valve rod (3) all run through described valve body (1)，Described first valve rod (5) and described second valve rod (3) be arranged in parallel，Described first movable valve plug (4) and described second movable valve plug (2) be arranged in parallel，Described first valve rod (5) is all fixing with a cross bar (6) with described second valve rod (3) top to be connected，Described cross bar (6) can drive described first movable valve plug (4) relatively described first fixed valve plug patch close or remote from，Described cross bar (6) can synchronize to drive described second movable valve plug (2) relatively described second fixed valve plug (7) patch close or remote from.
Further, described first movable valve plug (4) is provided with the first buckle (8), and described first fixed valve plug is provided with the first draw-in groove matched with described first buckle (8).
Further, described second movable valve plug (2) is provided with the second buckle (9), and described second fixed valve plug (7) is provided with the second draw-in groove matched with described second buckle (9).
Further, described first movable valve plug (4) is identical with described first fixed valve plug material, described second movable valve plug (2) is identical with described second fixed valve plug (7) material, and described first movable valve plug (4) is different from described second movable valve plug (2) material.
The present invention has the advantage that and has the benefit effect that owing to adopting technique scheme, the setting of two movable valve plugs can improve the rejection effect of butterfly valve, even if having a spool to go wrong nor affect on being continuing with of butterfly valve, it is possible to reduce the number of times changing butterfly valve, extend the service life of butterfly valve.
