Abstract
The utility model pertains to the field water pressure buffering device technology, specifically to a novel water hammer arrestor, which is characterized in that the water hammer arrestor includes a tank, a switch-in pipe connecting the tank bottom and the pipeline main pipe, air bags provided in the tank and a pressure regulation appliance. Compared with the traditional slow-closed back valve, the novel water hammer arrestor of the utility model can more thoroughly eliminate water hammer, greatly reduces the durable requirements to pipeline and water pump and saves cost. The utility model is especially suitable for water pipe with high pressure and long distance.
Description
Technical field
The utility model belongs to hydraulic pressure damping device technical field, specifically is a kind of novel water-hammer arrester.
Background technique
In the pressure pipe road was arranged, when playing pump, termination of pumping, opening/shutting valve, change wheel speed, blade angle adjusting flow, the flow velocity of water sharply changed, and produces water hammer effect.
The harm main forms that water hammer effect produces has:
One, water hammer pressure is too high, causes water pump, valve and pipeline destroyed; Water hammer pressure is low excessively, and pipeline is stranded unstability and destroys.
Two, water pump counter-rotating speed is too high or coincide with the critical speed of rotation of water pump assembly, and stops Umklapp process suddenly or motor is restarted, thereby causes the permanent deformation of motor rotor, the strenuous vibration of water pump assembly or the fracture of coupling shaft.
Three, water pump refluence amount is excessive, causes that ductwork pressure descends, and the water yield reduces, and influences normal water supply.
For fear of the destruction of water hammer to water pump, the outlet at water pump is provided with safety check usually.When pressure during, can use buffer valve greater than 2.0mpa.The buffer valve simple structure, two periods of termination of pumping time-divisions close, and the shut-in time can be adjusted among a small circle.
Although safety check has been protected water pump, still the water hammer energy is not shifted away, can cause damage to pipe fitting.Therefore requiring the pipe fitting proof pressure usually is several times of normal operating pressure, and pressure is high more, makes to require also highly more, has improved construction cost.
Summary of the invention
The utility model provides a kind of novel air sac type water-hammer arrester at above-mentioned the deficiencies in the prior art, by being arranged on the water-hammer arrester in the pipeline, can avoid water hammer effect infringement water pump, pipe fitting and other equipment effectively.
Concrete technological scheme of the present utility model is:
A kind of novel water-hammer arrester is characterized in that described water-hammer arrester comprises that tank body, tank base and pipeline be responsible for the access tube that links to each other, be located at air bag and regulator in the tank body.
Be provided with a buffering water chamber in the described tank body.
Described regulator comprises safety valve, atmospheric valve, the pressure gauge that is complementary with air bag.
The external liquid-discharging tube of described access tube.
Described access tube can in establish a safety check.
The working state of the utility model water-hammer arrester is as follows: inject in the air bag be equivalent to 0.9 times of working pressure of water delivery or with the pressurized air of working pressure equal pressure, make rubber pneumatic bag be attached on the inner tank wall closely; When the water transport pipeline proper functioning, enter a part of water in the tank body, be full of the buffering water chamber, make air bag be the floating state; When unexpected termination of pumping, produce a low pressure that is lower than static pressure the early stage of water hammer ripple in the pipe-line system, main pipe pressure reduces, airbag inflation in the canceller goes into to be responsible for the hydraulic pressure that is stored in the container, and low pressure is relaxed, when malleation water hammer ripple arrives this canceller, the rule that gas in the air bag is inversely proportional to by pressure and volume when temperature-resistant is shunk, and reaches a transient equiliblium, thereby has eliminated the water hammer greater than working pressure.
The utility model is simple in structure, installation and maintenance are convenient, can not produce the cutout water hammer when using; Be contained in the air bag in the tank body, air and water separated often tonifying Qi; Can adapt to the big water transport pipeline of variation in pressure, for example adjustable speed water pump send water system; Compare with a plurality of equalizing tanks, the utility model provides a kind of more economical and practical elimination water hammer equipment; The utility model can also cooperate the automatic control of water pump, the pressure wave when eliminating the water pump start-stop.
The novel water-hammer arrester of the utility model is compared with traditional buffer valve, has eliminated water hammer comparatively up hill and dale, and the durable requirement of pipeline and water pump is reduced greatly, has saved cost, and the utility model is particularly useful in the aqueduct of pressure height, distance.
Description of drawings
Fig. 1 is the utility model water-hammer arrester structural representation
Wherein, tank body 1, access tube 2, air bag 3, buffering water chamber 5, manhole 11, liquid-discharging tube 21, atmospheric valve 41, pressure gauge 42, valve protection mouth 43, framework 50.
Embodiment
Novel water-hammer arrester comprises that tank body 1, tank body 1 bottom and pipeline be responsible for the access tube 2 that links to each other, be located at air bag 3 and regulator in the tank body, be provided with one in the tank body 1 and cushion water chamber 5, but these water chamber 5 inside construction frameworks 50 is in the hope of more firm.
Regulator comprises the safety valve, atmospheric valve 41, the valve protection mouth 43 that are complementary with air bag 3 of being located at tank body 1 top, and the outer pipe is connected to the pressure gauge 42 of tank body 1 bottom.
Described access tube 2 external liquid-discharging tubes 21, access tube 2 can in establish a safety check.
Manhole 11 can be set in tank body 1 side and cat ladder overhauls with convenient.
The working state of this water-hammer arrester is as follows: inject in the air bag 3 be equivalent to 0.9 times of working pressure of water delivery or with the pressurized air of working pressure equal pressure, rubber pneumatic bag 3 is attached on tank body 1 inwall closely; When the water transport pipeline proper functioning, enter a part of water in the tank body 1, be full of buffering water chamber 5, make air bag 3 be the floating state; When unexpected termination of pumping, produce a low pressure that is lower than static pressure the early stage of water hammer ripple in the pipe-line system, main pipe pressure reduces, air bag 3 expands in the canceller, and the hydraulic pressure that is stored in the tank body 1 is gone into to be responsible for, and low pressure is relaxed, when malleation water hammer ripple arrives this canceller, the rule that gas in the air bag 3 is inversely proportional to by pressure and volume when temperature-resistant is shunk, and reaches a transient equiliblium with the water hammer that enters tank body 1, thereby has eliminated the water hammer greater than working pressure.
Should be noted that: the utility model not only is confined to the foregoing description, and the technological scheme of every buffering water chamber that utilizes air bag or air bag and cooperate with air bag all should be thought and falls into protection domain of the present utility model.
