Dynamic pipe clip valve 10.In use, the bottom of cell body 20 is equipped with earth of positive pole tapping equipment 30, corrosion-resistant pneumatic tubing clip valve
10 two connecting flanges 4 are fixedly connected with the flange of the flange of earth of positive pole tapping equipment 30 301 and follow-up pipeline respectively, titanium system
Gas nozzle 2 is connect with external tracheae, and is locked by titanium nut 33, and the earth of positive pole can pass through from channel 5.When needing to anode
When the flow of mud is regulated and controled, under the control of air-channel system, when intake valve is opened when exhaust valve closure, compressed air is through outer
Portion's tracheae simultaneously by the stomata of titanium gas nozzle 3 34 enter valve body 1 in, the effect of compressed air, inner sleeve 2 due to have elasticity and
To contract, free air space reduces in channel 5, to realize the purpose for reducing earth of positive pole flow；It is vented when intake valve is closed
When valve is opened, compressed air is laid down from valve body 1, and inner sleeve 2 is no longer influenced by the effect of compressed air and gradually restores to the original state, and is led to
Free air space increases in road 5, to realize the purpose for increasing earth of positive pole flow.Corrosion-resistant pneumatic tubing clip valve is installed on electrolytic cell
10, since 10 air-tightness of corrosion-resistant pneumatic tubing clip valve is good, antiseep effect is good, and intensity is high, is hardly damaged, can be long-term used in
In the high environment of corrosivity intensity, service life is long, so stability is more preferable in use for electrolytic cell, and then improves electricity
Solve the service life of slot entirety.
Above-described is only some embodiments of the present invention, it should be appreciated that the ordinary skill people of this field
For member, without departing from the concept of the premise of the invention, it can also according to the above description be improved or be exchanged, and be owned
These are improved and exchange should all belong to the protection domain of appended claims of the present invention.
