Abstract

The invention relates to the technical field of pipe cleaning valves, and discloses a vibration resistant type pipe cleaning valve. The valve comprises a shell, and a ball body arranged in the shell;an inlet channel is formed in the ball body, an outlet channel is coaxially arranged at the position, corresponding to the inlet channel, of the ball body, the diameter of the outlet channel is smaller than the diameter of the inlet channel, an inlet and outlet channel is vertically formed in the bottom of the ball body, a discharge opening is formed in the position, corresponding to the inlet andoutlet channel, of the bottom of the shell, a flange assembly is arranged at the position corresponding to the discharge opening, a plunger column matched with the inlet and outlet channel is arranged in the inlet and outlet channel, and can seal the inlet and outlet channel, the lower end of the plunger column is fixedly connected with a rod body, and the lower end of the rod body extends out ofthe flange assembly downwards. A valve base is arranged outside the inlet channel and the outlet channel of the ball body in abutting joint manner, and the other end of the valve base is in abut joint with the shell. The vibration resistant type pipe cleaning valve can avoid material remaining, vibration caused by turbulent flow is avoided, and taking and putting of the pipe cleaning device are not affected; and the valve is simple in structure, stable in work and easy and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of pigging valves, in particular to an anti-vibration pigging valve. Background technique [0002] Pig valve, also known as PIG valve, is a new type of valve used as a launching or receiving device for pigs (pig ball, leather bowl pig, foam pig, etc.). The pigging valve is mainly suitable for maintenance work such as cleaning the inner wall of the pipeline in long-distance pipelines such as oil, water, petroleum, and natural gas. When in use, open the bonnet of the pigging valve set on the upstream pipeline, put in the pig and release it, the pig will flow downstream along the pipeline with the medium and clean the dirt on the pipe wall, when it reaches the set on the downstream pipeline When using the pigging valve, open the bonnet of the pigging valve and take out the pig. It is widely used in petroleum, chemical industry, gas, water delivery, printing and dyeing, food and other fields. It is an indispen...
