I. Introduction of GHF-1 fire-resistant breathing valve

   工作原理是用弹簧限位阀板,由正负压力决定或呼或吸。 The working principle of the fire breathing valve is to use a spring limit valve plate, which is determined by positive and negative pressure or exhales or sucks. 呼吸阀 打开呼出气体泄放正压;当容器承受负压时,防火呼吸阀打开吸入气体泄放负压。 The breathing valve should have both positive and negative pressure relief functions. Specifically: when the container is under positive pressure, the breathing valve opens and the exhaled gas releases positive pressure; when the container is under negative pressure, the fire breathing valve opens to inhale the gas. Pressure. This ensures that the pressure is within a certain range and that the container is safe. At the same time, there is a fire blocking plate at the inlet and outlet of the breathing valve. The fire stopper is used to prevent the mixed gas in the storage tank from contacting with the air, which will cause backfire and explosion, so it is necessary to install a fire breathing valve.

Three, GHF-1 fire breathing valve installation method
 
Put the tank top breathing valve
① (as shown below, the same below), then remove the bezel
② Folding from the splice tube
③Into the tank
④ Flatten the inside, then place the fixed plate and disk at the center of the joint pipe flange, and put the electrostatic ground wire
⑤Press the gasket under the connection bolt of the breathing valve, and then reinstall the breathing valve.
呼吸阀 挡板吊装于呼吸阀与油罐的接合管下方,以减少大呼吸过程中油气外溢的损失。 1. The breathing valve baffle is hoisted under the joint pipe of the breathing valve and the oil tank to reduce the loss of oil and gas overflow during the large breathing process.
2. Please indicate the name, specifications and drawing number when ordering. Tank top splice tube actual height n.
