Abstract
The utility model relates to an air bag combined type water-hammer arrestor which is characterized in that the water-hammer arrestor is provided with a section of concentric-sleeve-tube-shaped casing which is connected with a water channel. An inner sleeve tube of the casing is a hammer-sucking tube which is distributed with small water pores, and a rubber air bag is arranged in the circular enclosed space between the external side of the hammer-sucking tube and an outer sleeve tube. One end of the casing is connected with a quick-action closing check valve in series, a valve flap of the quick-action closing check valve moves away a valve base by the push of water stream and communicates with the water channel, and a spring valve handle drives the valve flap to restore for matching with the valve base to close. The air bag combined type water-hammer arrestor is in a combined structure which integrates quick-action closing check and air bag energy absorption. The utility model has the advantages of compact structure, small volume, small installing space, convenient installation, good hammer-sucking effect, etc.
Description
The utility model relates to a kind of water-hammer arrester.
Along with the development of highrise building, cause the wasting phenomenon of the damage of equipment and water resource increasing owing to ignore the control of water hammer, the harm that water hammer takes place after the termination of pumping has caused numerous project planners' attention.
The purpose of this utility model provides a kind of air bag combined type water-hammer arrester, reduces and avoid the harm of water hammer, prevents to cause the damage of equipment and the wasting phenomenon of water resource.The technical scheme of the utility model air bag combined type water-hammer arrester: it has one section tubular housing of the concentric locking collar that is communicated with water channel, the housing inner sleeve is the suction hammer pipe that is distributed with little water hole, the annular enclosed space of inhaling between hammer tube outside and the outer tube is equipped with rubber pneumatic bag, quick-closure check valve of housing one end series connection, the flap of quick-closure check valve is subjected to current to promote to lift off a seat to be communicated with the water route, and drives flap by the spring valve rod and recover to cooperate with valve seat and close.
Above-mentioned rubber pneumatic bag is regulated mouth with the blowing pressure and is connected.
Above-mentioned the blowing pressure is regulated mouth and is connected with pressure meter.
The utility model is eliminated the principle of water hammer: we know, cause two principal elements of water hammer harm to be: to return the closing velocity of valve and the rigidity of tube wall.The fast more water attack that then produces of closure of check ring speed can be more little, its reason is: in the unexpected termination of pumping of water pump, valve wall rapid closing under the effect of spring of fast wall flap valve can reduce the water column cutout and be drawn empty distance, because this distance is directly proportional with the water hammer energy.Flexible tube wall-air bag.Air bag draws empty position moisturizing to quilt in termination of pumping, reduce the water column cutout once more and drawn empty distance, air bag only is charged to the 70%-80% of pump head when inflation, there is the water of 20%-30% to contain between suction hammer pipe and air bag, hydraulic pressure in the pipeline in a single day be lower than the air pressure air bag immediately the hydraulic pressure of containing to pipeline, replenish cutout.Can reduce the 60%-65% that water hammer is pressed by closing soon with the air bag moisturizing, remaining water hammer presses the acting in conjunction by air cushion and caoutchouc elasticity to be absorbed, and can guarantee the safety of pipeline fully.
When normal water supply, current back down flap 5, flow through suction hammer pipe 3 and enter pipe network.When termination of pumping, flap S closes rapidly under the effect of spring 4, realizes the above-mentioned said effect that adds air bag of closing soon when closing, and reaches the purpose of eliminating water hammer.
Advantage of the present utility model: this air bag combined type water-hammer arrester is to integrate fast apolipsis to return combining structure with the air bag energy-absorbing, have compact conformation, volume is little, installing space is little, easy for installation, inhale advantages such as hammer is effective.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-housing, 2-rubber pneumatic bag, 3-inhale that hammer pipe, 4-spring, 5-flap, 6-valve seat 7-inflation are regulated and chewed, 8-pressure meter, 9-connector, 10-water supply condition, 11-are inhaled and hammered operating mode into shape.
Air bag combined type water-hammer arrester has one section tubular housing 1 of concentric locking collar that is communicated with water channel by connector 9, housing 1 inner sleeve is the suction hammer pipe 3 that is distributed with little water hole 12, the annular enclosed space of inhaling between hammer tube outside and the outer tube is equipped with rubber pneumatic bag 2, quick-closure check valve of housing one end series connection, the flap of quick-closure check valve is subjected to current to promote to lift off a seat to be communicated with the water route, and drives 5 flaps by 4 spring valve rods and recover to cooperate with 6 valve seats and close.Rubber pneumatic bag is regulated mouth 7 with the blowing pressure and is connected, and the blowing pressure is regulated mouth and is connected with pressure meter 8.
