Abstract
The utility model provides a water hammer eliminator consisting of a casing, a flange, a peltry, a balance hood, a meter valve, a pressure meter and an air nozzle, wherein, the peltry is arranged in the casing, the balance hood is arranged between the casing and the peltry and keeps certain distance away from the casing, the peltry is fixed at an air inlet on the top of a seal head through a peltry joint, a fastening nut and a collar nut and is connected with the meter valve and the pressure meter through the peltry joint and a tee joint T, the air nozzle is arranged on the other joint of the tee joint T, and a water stop cushion and an O-shaped seal ring are respectively arranged on the joining part between the peltry joint and the air inlet of the seal head. The utility model eliminates the water hammer through the peltry filled with air, thereby achieving the function of quickly, sensitively and reliably eliminating the water hammer with good effect. Furthermore, the water hammer eliminator is directly connected with an interface in a pipeline network with easy assembly and use, simple structure, easy manufacture and low cost and without any drags effect.
Description
1, technical field
The utility model relates to a kind of water-hammer arrester that is used to eliminate the pipe network water hammer.
2, background technique
Along with the development of tall building, because the control of ignoring water hammer causes the wasting phenomena of the damage of equipment, annex and water resources increasing.In the open type water supply piping system of automatic start-stop of pumping or pumping accident; when termination of pumping, will inevitably produce strong water hammer; thereby cause managing the internal pressure rapid change; produced very big instantaneous pressure; cause the interior equipment of pump house, pipeline, safety check etc. to be destroyed; cause greater loss; and the prior art that prevents water hammer adopts slow closed check damper or multifunctional water pump control valve mostly; complex structure not only; manufacture cost is higher relatively; and being the overflow-type structure, the resistance that pipeline is caused is bigger, has increased the operation energy consumption of system.
3, model utility content
In view of above-mentioned the deficiencies in the prior art, the utility model provides a kind of simple in structure, easily manufactured, water-hammer arrester that cost is low.
The technological scheme that its technical problem that solves the utility model adopts is: water-hammer arrester is by housing, flange, leather bag, the balance cover, the table valve, the gentle composition of chewing of pressure gauge, leather bag places in the housing, housing is made up of cylindrical shell and end socket, wherein, the cylindrical shell lower end is equipped with to connect and is used flange, the upper end is an end socket, balance is located between housing and the leather bag, and have certain intervals with housing, the balance cover is made up of shroud and base plate, and base plate by screw in the shroud lower end, the shroud upper end is fixed on the end socket, shroud and base plate are made by the metal otter board that is covered with aperture, leather bag is fixed on the suction port place at end socket top by leather bag joint and locking nut and Female connector fittings, and at the suction port place by the leather bag joint, three connect table valve and pressure gauge, another interface of threeway is equipped with gas to be chewed, and is provided with waterstop pad respectively at the joining portion of the suction port of leather bag joint and end socket, O shape water stop ring.
Profitable fruit of the present utility model is, employing is given the leather bag of inflation body and is eliminated water hammer, can reach the quick rapidly sensitive effect of eliminating water hammer reliably, simultaneously, interface direct and in the pipe-line system is connected, and is easy to install, there is not any drag effects, and simple in structure, convenient processing and manufacture, cost is low.

Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1, flange, 2, housing, 3, leather bag, 4, balance cover, 5, the leather bag joint, 6, waterstop pad, 7,0 shape water stop ring, 8, locking nut, 9, Female connector fittings, 10, threeway, 11, the table valve, 12, pressure gauge, 13, gas chews, 14, screw, 201, cylindrical shell, 202, end socket, 203, suction port, 401, shroud, 402, base plate, 403, aperture.
5, embodiment
Explain below below in conjunction with Fig. 1 water-hammer arrester of the present utility model being done.
As shown in Figure 1, water-hammer arrester of the present utility model is by housing (2), flange (1), leather bag (3), balance cover (4), table valve (11), gentle the chewing of pressure gauge (12) (1 3) formed, leather bag (3) places in the housing (2), housing (2) is made up of cylindrical shell (201) and end socket (202), wherein, cylindrical shell (201) lower end is equipped with and is connected with flange (1), the upper end is end socket (202), balance cover (4) is located between housing (2) and the leather bag (3), and have certain intervals with housing (2), balance cover (4) is made up of shroud (401) and base plate (402), and base plate (402) is fixed on shroud (401) lower end by screw (14), shroud (401) upper end is fixed on the end socket (202), shroud (401) and base plate (402) are made by the metal otter board that is covered with aperture (403), the effect of balance cover (4) has: the one, and the leather bag (3) that gives the inflation body can be located, play the positioning balance effect, the 2nd, can make the impact of water hammer ripple guide whole leather bag (3) surface rapidly into by the aperture (403) on the balance cover (4), reach rapid elimination water hammer.Leather bag (3) is located by the suction port (203) that leather bag joint (5) and locking nut (8) and Female connector fittings (9) are fixed on end socket (202) top, and locate to connect table valve and pressure gauge (12) by leather bag joint (5), threeway (11) at suction port (203), another interface of threeway (11) is equipped with gas chews (13), is provided with waterstop pad (6), O shape water stop ring (7) respectively at the joining portion of the suction port (203) of leather bag joint (5) and end socket (2Q2).The effect of pressure gauge (12) is, give inflation body pressure in order to check, its pipe internal pressure with place pipe network system installed position is equated, leather bag this moment (3) can be close to good balance cover (4) inwall of permeability, can promptly absorb the positive and negative water hammer in the pipe network.
