now many pipes are sets of exhaust valve, then set up the meaning of the exhaust valve, do you know?

。 Exhaust valve should be larger displacement, when the pipeline atc water filling can be achieved in a very short period of time quickly exhaust back to normal water supply capacity.

b。 Exhaust valve in tube with negative pressure, the piston should be able to quickly open, quickly a large number of inhaled air outside, do not damage due to negative pressure to ensure that the pipeline. And able to concentrate in the pipeline under working pressure trace air out.

c。 Exhaust valve should be higher air closing pressure, in a short period of time, the piston should be enough to power the pipe air emissions and improve the efficiency of water.

d。 The water of the exhaust valve closed pressure should not be greater than zero. 02 MPa, under lower water pressure can close the discharge Industrial Valves, to avoid a large number of water gushed out.

e。 Exhaust valve shall be stainless steel ball float ( Floating barrels) For opening and closing parts.

f。 On the exhaust valve body shall be equipped with strike to protect inner barrel, in case of a large number of exhaust after high speed water floating ball directly ( Floating barrels) Caused by the floating ball, Floating barrels) The early damage.

g。 For DN≥ 100 fission structure is used in the exhaust valve is composed of a large number of exhaust valve and automatic exhaust valve, in order to meet the requirements for the use of the pipeline pressure. Automatic exhaust valve should be used after lever mechanism, to greatly enlarge, floating ball buoyancy and close the water level is low, the sealing contact surface of the water impurity is not easy to, vent can't be blocked, the anti-clogging performance can be greatly improved. Under the condition of high pressure at the same time, due to the effect of strength of the compound leverage, can make the floating ball and synchronous water level drops, open-close part will not be high pressure to absorb, as a traditional valve to exhaust.

h。 For high flow velocity, frequent start the operation condition of the water pump, diameter DN ≧ 100, impact to slow the water, exhaust valve should be mounted to the buffer valve. Buffer should plug valve can prevent a lot of water but do not affect a large number of exhaust, make water conveyance efficiency will not be affected, and effectively prevent the water hammer.
