The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
An air storage tank, as shown in fig. 1, comprises a tank body 1 and an exhaust assembly 2.
As shown in fig. 2, a pressure relief pipe 3 is fixedly connected to the upper end of the tank body 1, and an air outlet is formed in the wall surface of the tank body 1, so that the pressure relief pipe 3 is communicated with the tank body 1; the air outlet is coaxially arranged with the inner cavity of the pressure relief pipe 3, and the diameter of the air outlet is smaller than the inner diameter of the pressure relief pipe 3. The cylindrical surface of the pressure relief pipe 3 is also communicated with an air outlet pipe arranged along the radial direction, and the air outlet pipe is connected with a valve body 4 in series.
The exhaust assembly 2 is mounted in the pressure relief pipe 3 and comprises a one-way valve spool 21, a valve rod 22 and a pressure regulating assembly 23. The check valve core 21 is screwed at the end of the valve rod 22, and the valve rod 22 is driven by the pressure regulating assembly 23 to press the check valve core 21 on the air outlet hole, so that the air outlet hole is closed.
The valve stem 22 includes a piston portion 221 and a connecting portion 222 which are integrally formed. The piston portion 221 and the connecting portion 222 are coaxially disposed, and the diameter of the piston portion 221 is larger than that of the connecting portion 222. The piston part 221 is sleeved in the pressure relief pipe 3 and slides along the pressure relief pipe 3. The end of the connecting portion 222 is formed with a screw portion, and the check valve body 21 is formed with a screw hole to which the screw portion is screwed, so that the check valve body 21 is fixed to the end of the stem 22.
The pressure regulating assembly 23 includes a pressure regulating cover 231, and a pressure regulating spring 232 sandwiched between the stem 22 and the pressure regulating cover 231. The pressure regulating cover 231 covers the end of the pressure relief pipe 3 and is in threaded connection with the pressure relief pipe 3. An upper positioning post 233 is formed in the pressure regulating cover 231 in an axially extending manner, and one end of the pressure regulating spring 232 is sleeved on the upper positioning post 233 and abuts against the bottom surface of the pressure regulating cover 231.
