Abstract

The invention discloses a combined type ball valve provided with a corrugated pipe. The combined type ball valve comprises a valve body (1) provided with an inlet end (1.1) and an outlet end (1.2) as well as a valve core (2), wherein the valve core (2) is mounted in the valve body (1); sealing pieces (5) are arranged on two sides of the valve core (2); one end of the corrugated pipe (6) is fixedly connected with the outlet end of the valve body (1); and the end surface of one end of the corrugated pipe (6) is propped against the sealing piece (5) close to the outlet end (1.2) of the valve body (1). With the adoption of the combined type ball valve provided with the corrugated pipe, the external leakage point between the corrugated pipe and the ball valve can be eliminated.

Description

technical field [0001] The invention relates to the field of valves, in particular to a combined ball valve with bellows. Background technique [0002] Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of media. Bellows are widely used in pipelines and instruments, and are often used with ball valves. But the current ball valve is separate from the bellows, and the two are independent parts. When in use, the end of the bellows is connected to the joint of the ball valve, and the two are connected by threads or the like. The structure of this prior art has the following disadvantages: the bellows and the ball valve joint are connected by threads, etc., which increases external leakage points, that is, the connection between the two is unreliable, and there may be a risk of air or water leakage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combined ball valve with...
