Description
Technical field
The present invention relates to a kind of valve, particularly relate to a kind of feedwater piping combined type automatic control pressure vent.
Background technique
At present, during for ensureing that feedwater piping is washed by water, energy automatic high speed Exhaust Gas, can discharge in due to water flow the gas of separating out in time, thus reduce flowing water resistance, avoid booster phenomenon in normal water supply process; When pipeline generation negative pressure, the air inlet of energy automatic high speed, prevents the generation of water hammer, ensures the normal operation of pipeline; The mode that many employings single hole outlet valve and micro-exhaust valve use as tube exhaust valve, its shortcoming is: 1, high speed exhaust amount is little, can not gas in time in discharge conduit, and make watering pressure increase, water flow velocity is slow; 2, air valve closing pressure is little, easily when high speed exhaust, produces envelope valve phenomenon, loses high speed exhaust function; 3, water valve closing pressure is large, easily produces phenomenon of metalling run out; 4, size relief opening sealing pair flexible type, easily produces phenomenon of metalling run out; 5, when pipeline produces water hammer, outlet valve is without decompression protection, and fragile sealed member, makes outlet valve damage, and causes pipeline to run; 6, the noise produced during high speed exhaust is large, produces noise pollution; 7, coating layer and water logging parts, easily cause secondary pollution to water.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of feedwater piping combined type automatic control pressure vent, and its air displacement is large, can effectively avoid sealing valve, phenomenon of metalling run out, and not fragile, and exhaust efficiency is high, and environmental pollution is less.
For achieving the above object, the technical solution used in the present invention is: a kind of feedwater piping combined type automatic control pressure vent, comprise high-speed exhaust valve and micro-exhaust valve, gas exchanges can be carried out between described high-speed exhaust valve and micro-exhaust valve, an exhaust port is respectively provided with at the upper and lower two ends of high-speed exhaust valve, its center of inside position is provided with sealed ball float, upper cover has been bolted in the upper end of high-speed exhaust valve, be fixed with micro-exhaust valve at the upper right side of high-speed exhaust valve, be provided with water hammer Decompression valves interface in the end upper position, lower-left of high-speed exhaust valve.
As preferably, the bottom surface of described upper cover be each side provided with a caulking gum pad, the bolt of the left end of the end face of upper cover is provided with adjustment cushion block, adjustment cushion block is bolted the guard shield be engaged mutually with upper cover.
As preferably, the inside left end of described micro-exhaust valve is provided with O type rubber ring, micro-support of hesitating is provided with at the upper right side of micro-exhaust valve, be provided with micro-row in the upper end of micro-support of hesitating and fix pressure cap, bearing pin is fixed on the bottom of micro-support of hesitating, and is connected with the lever and floating being positioned at micro-exhaust valve center of inside position at pin the tip of the axis.
By above setting, the present invention has following beneficial effect:
1, porting adopts transformation airflow design, and smooth in exhaust, greatly reduces exhaust flow resistance;
2, upper air vent adopts the design of exhaust chamber-dividing counter-blowing formula, makes sealed ball float when large pressure exhaust 8bar, does not shut exhaust port;
3, operating space is large, only need this valve with being manually coated on pipeline, exit face is to branch line direction;
4, when water ball float rises to sealing pair, with line style contact sealing, pressure, when 0. 1bar, seals completely;
5, large exhaust port adopts the sealing of combined type two-wire type, makes sealing pair water shutoff when hydraulic pressure 0. 1bar, the sealed mouth not modification when 30bar pressure; Small de-air hole adopts spacing line style to seal, and without abrasion deformation phenomenon, the frequent nothing that opens and closes seeps water;
6, when pipeline produces water hammer: adopt super setting pressure, automatically drain design;
7, curved surface noise reduction design is adopted, the noise produced when effectively can reduce high speed exhaust.
