Gas cutting-off machine

Abstract

The invention relates to a gas cutting-off machine comprising a cylinder, a partition board and a water inlet pipe. Two sides of the cylinder are provided with a gas inlet pipe and a gas outlet pipe;the middle part of the cylinder is provided with the partition board which divides the cylinder into a gas inlet cylinder and a gas outlet cylinder; the partition board is internally provided with a sealing cavity; the top and the two sides of the partition board are exposed outside the cylinder; the bottom surface of the partition board is lower than the gas inlet pipe and the gas outlet pipe andkeeps a distance with the bottom of the cylinder; the parts of the partition board, which are exposed outside the cylinder, are provided with a partition board pressure gage and a control pipe; the cylinder is provided with the water inlet pipe; and the whole cylinder is fully sealed. The gas cutting-off machine has reasonable structural design and can replace the blind plate to fully cut off thegas safely and reliably, thereby effectively guaranteeing the safety of the operator and improving the work efficiency.

Description

technical field [0001] The invention relates to a cut-off device, in particular to a gas cut-off device. Background technique [0002] In the process of field operation, it is often necessary to cut off the gas. In the existing gas cut-off device, the valve is not a reliable cut-off device, only the blind plate is a reliable cut-off device. Or various impurities are mixed between the valve body and the valve seat, causing the valve to be lax and unable to completely cut off the gas. But the method of adopting the blind plate to cut off the gas needs to be carried out when there is gas, the operation procedure is more complicated, there are many participants, and vicious accidents of fire, explosion and poisoning occur from time to time, which is a difficult problem in the gas operation. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art, and provides a gas cut-off device with reasonable structural design, safe and convenient opera...

Problems solved by technology

[0002] During the field work, it is often necessary to cut off the gas. In the existing gas cut-off device, the valve is not a reliable cut-off device, only the blind plate is a reliable cut-off device. After a period of use, the valve plate that controls the gas inlet and outlet Or various impurities are mixed between the valve body and the valve seat, causing the valve to be lax and unable to completely cut off the gas

However, the method of cutting off the gas by using the blind plate needs to be carried out when there is gas. The operation procedure is relatively complicated, and there are many people involved. Fire, explosion, and poisoning accidents occur from time to time, which is a long-standing problem in the gas operation.
