Exhaust butterfly valve for automobile

Abstract

The invention discloses an exhaust butterfly valve for an automobile. The exhaust butterfly valve comprises a valve body. A valve seat is mounted on the inner wall of the valve body, a butterfly plateis mounted in the middle of the inner wall of the valve seat, the butterfly plate comprises a plate body, an inner hexagon screw, a seal ring and fixed rings, the seal ring is mounted in the middle of the plate body through the inner hexagon screw, the fixed rings are fixedly connected to the middle parts of upper and lower ends of the left side of the plate body, a butterfly plate is in throughconnection to the center of the valve body, a bottom cover is fixedly connected to the center of the bottom surface of the valve body, a self-lubricating bearing is mounted at the connection of the butterfly rod and the top end of the inner wall of the valve body, a supporting plate is fixedly connected to the top end of the valve body through a bolt, a push rod is in threaded connection to the top end of the butterfly rod, an air cylinder is mounted at the right end of the push rod, an air cylinder control device is mounted on the right side of the upper surface of the air cylinder, and the air cylinder control device comprises an air cylinder controller, a power supply and an electromagnetic valve. The exhaust butterfly valve for the automobile is simple in structure and good in sealingeffect and has very high practicality.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to an exhaust butterfly valve for automobiles. Background technique [0002] With the increasing requirements for the braking system of commercial vehicles, upgrading the traditional braking system can no longer fully meet the needs of customers, so another braking method-auxiliary braking has emerged as the times require. Although auxiliary braking It can't reach the braking force output by the main braking system, but the whole vehicle does not need to use such a large force to brake the vehicle every time during driving. , It can also play the role of braking and deceleration, so the exhaust butterfly valve was born as a new auxiliary product. [0003] The existing exhaust brake butterfly valve has poor sealing effect, and the sealing ring and the inner cavity are pressure-forced seals, so the operating torque when the valve is opened and closed is relatively larg...

[0002] With the increasing requirements for the braking system of commercial vehicles, upgrading the traditional braking system can no longer fully meet the needs of customers, so another braking method-auxiliary braking has emerged as the times require. Although auxiliary braking It can't reach the braking force output by the main braking system, but the whole vehicle does not need to use such a large force to brake the vehicle every time during driving. , can also play the role of braking and deceleration, so the exhaust butterfly valve was born as a new auxiliary product

[0003] The existing exhaust brake butterfly valve has poor sealing effect, and the sealing ring and the inner cavity are pressure-forced seals, so the operating torque when the valve is opened and closed is relatively large, which increases the energy loss of the engine and also affects the opening and closing of the valve. Because of the strong gas pressure, the butterfly plate is easily deformed by impact and affects the braking effect. Therefore, an exhaust butterfly valve for automobiles is designed. The exhaust butterfly valve for automobiles has a simple structure, good sealing effect, and strong Practicality
