Claims

[Scope of Claim for Utility Model Registration] (1) A safety release valve that opens and closes a gas release valve using the movement of the liquid level that changes up and down in response to minute pressure based on the principle of manometer, and is a cylinder filled with liquid. A bottomed liquid receiving cylinder that receives water overflowing from the top surface of the external cylinder is installed concentrically and integrally on the upper outer periphery of the external cylinder with a bottom. A cylinder for forming a liquid path is erected, and a slit-like separation is made between the cylinder and the outer cylinder, and a plurality of partition walls having lower edges with a small difference in height are installed between the cylinder for forming a liquid return path and the gas pipe. In addition to providing the liquid receiving cylinder vertically, a small hole is provided at the joint between the bottom of the liquid receiving cylinder and the outer cylinder to the extent that capillarity is not noticeable between the respective partition walls, and the lower surface of the short partition wall and the gas pressure rises to form bubbles. The structure is configured such that the difference in height between the water level directly below the gas pipe when the gas is discharged onto the water surface of the outer cylinder is larger than the difference between the liquid level in the receiving cylinder and the liquid level in the condensate channel, and the difference in water level between the upper and lower sides is reduced. This wet type low pressure safety release valve for gas is characterized in that the gas discharge path and the liquid recovery path are separated. (2) The wet-type low-pressure safety release valve for gas according to claim 1, wherein the return liquid path is formed in a pipe shape.
