Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of technical solution: automatic blow off valve valve air relief before a kind of pumping of screw pump, packet
Anti-gray component 1, exhaust head 2, sealing cover 3, flange 1, valve body 5 and flange 26 are included, valve body 5 is assemblied in 26 upper surface of flange
Middle position, flange 1 are assemblied in 5 upper surface of valve body, and sealing cover 3 is mounted on one 4 upper surface of flange, exhaust head 2 by bolt
It is assemblied in 3 upper surface of sealing cover.
Anti-gray component 1 is assemblied in 3 upper surface of sealing cover, and anti-gray component 1 includes threaded rod 11, through-hole 12, nut 13, dust-proof
