Reducing two-way pipe joint

Abstract

The invention discloses a reducing two-way pipe joint which comprises a joint body, the front end of the joint body is movably connected with a large-diameter pipeline, the rear end of the joint body is movably connected with a small-diameter pipeline, the middle of the joint body is fixedly connected with a fixing and supporting mechanism, the fixing and supporting mechanism comprises a fixing ring, a column is fixedly connected to the lower end of the fixing ring, a fixing plate is fixedly connected to the lower end of the column, a connecting arm is arranged on the side surface of the fixing ring, and a pressing plate is fixedly connected to the front end of the connecting arm. According to the reducing two-way pipe joint, the position of the small-diameter pipeline can not be changed, the small-diameter pipeline can be conveniently fixed to the rear end of the joint body, after connection is completed, the joint body and the large-diameter pipeline and the small-diameter pipeline at two ends can be supported all the time, the force borne by the joint body is shared, and the joint body can be prevented from being loosened due to large pressure.

Description

technical field [0001] The invention relates to the technical field of pipe joints, in particular to a variable-diameter two-way pipe joint. Background technique [0002] The pipe joint is a connection tool between pipes and a detachable connection point between components and pipes. Pipe joints are used for straight-line connections such as instruments, and the connection forms include socket welding or threaded connections. It is mainly used for small-diameter low-pressure pipelines, used for parts that need to be assembled and disassembled frequently, or used for final adjustment of pipelines using threaded pipe fittings. The structural form should adopt the metal surface contact sealing structure. The structural form of the gasket seal is usually used on general pipelines such as water, oil and air. When the variable diameter two-way pipe joint is used, the two sets of pipes are often of different heights. Forcibly pulling to the same height requires free hands to supp...

Problems solved by technology

The structural form should adopt the metal surface contact sealing structure. The structural form of the gasket seal is usually used on general pipelines such as water, oil and air. When the variable diameter two-way pipe joint is used, the two sets of pipes are often of different heights. Forcibly pulling to the same height requires free hands to support the docking operation. One-handed docking is time-consuming, laborious and troublesome. The joints continue to cause pressure, which is easy to cause the joints to loosen. In order to solve the above problems, we propose a reducing two-way pipe joint
