A gas control device

Abstract

The application discloses a gas control device, and belongs to the technical field of petroleum equipment. The gas control device comprises a first pipe body, an air inlet and an air outlet are formed in the first pipe body, an air inlet channel and a gas control channel are formed in the first pipe body, one end of the air inlet channel is communicated with the air inlet, the other end of the air inlet channel is communicated with the gas control channel, the air outlet is communicated with one end of the gas control channel which is away from the air inlet channel, the gas control channel has a first end communicated with the air inlet channel, a second end communicated with the air outlet and a third end between the first end and the second end, the inner diameter of the gas control channel gradually decreases in the direction from the first end to the third end, and the inner diameter of the gas control channel gradually increases in the direction from the third end to the second end. The inner diameter of the gas control channel is first reduced and then increased, so that the structure of the air channel is similar to that of a Venturi tube, the maximum steam flow through the gas control channel is controllable, and the steam flow discharged by the gas control device is uniform.
