Abstract

The utility model discloses a liquid type blocking valve for gas pipelines. The liquid type blocking valve comprises a lower box and an upper box, wherein the lower box and the upper box are respectively in a cuboid shape. An inner cavity of the lower box is connected with an inner cavity of the upper box through a liquid pipeline, and a pneumatic valve is arranged in the middle of the liquid pipeline. The two sides of the lower box are respectively connected with a gas pipeline, and gas can enter the gas pipeline on one side from the gas pipeline on the other side through the lower box. The lower box is further provided with a water pump. A water inlet of the water pump is communicated with the inner cavity of the lower box, and a water outlet of the water pump is communicated with the inner cavity of the upper box. The liquid type blocking valve for the gas pipelines can avoid the situation that the valve cannot be closed completely because the valve is deformed or stuck due to influences of high temperature and impurities such as dust and tar. The sealing effect is very good.
