Abstract
The utility model discloses a vacuum inhibition apparatus matched with non-negative pressure water supply equipment. The vacuum inhibition apparatus comprises a flange, a sealing drum, a sealing piston, a floating ball, and a sealing cover. The floating ball is connected with a water chamber sealing plate via a floating ball support. The water chamber sealing plate and an air chamber sealing plate in the sealing drum form an air storage chamber which is connected with a storage via an air passage pipeline. A water pressure sensor and an air pressure sensor are respectively mounted on the water chamber sealing plate and the air chamber sealing plate. The sealing piston is mounted on the water chamber sealing plate via a sealing piston sleeve. The water pressure sensor and the air pressure sensor are led out of the sealing drum via signal lines. The vacuum inhibition apparatus can store air via the air storage chamber and rapidly inhibit and eliminate non-negative pressure when the non-negative pressure is generated. The vacuum inhibition apparatus is reliable in structure, quick in response, and convenient for large-batch production and processing.
Description
Technical field
The utility model relates to vacuum eliminating device, is particularly applicable to the supporting vacuum eliminating device of steady flow compensator in non-negative pressure water-supply installation.
Background technology
Steady flow compensator is the main core component of non-negative pressure water-supply installation; play the vacuum problem when eliminating and destroying water pump operation together with vacuum suppresser; play the effect that makes full use of tap water pressure simultaneously; but the vacuum eliminating device of most is to connect with air; or realize and shutting down according to hydraulic pressure; be not real elimination and the formation that suppresses vacuum, do not reach result of use, occur frequent shutdown problem.
Summary of the invention
The utility model provides a kind of non-negative pressure water-supply installation supporting vacuum eliminating device in order to solve deficiency of the prior art, can store air by atmospheric pressure cavity, when producing negative pressure, can suppress rapidly and eliminate, reliable in structure, be swift in response, and be convenient to large batch of production and processing.
The vacuum eliminating device that non-negative pressure water-supply installation is supporting, comprises flange, sealing drum, packed-piston, ball float, seal cover, and described ball float is connected with water cavity sealing plate by ball float support; In sealing drum, water cavity sealing plate and air cavity sealing plate form an air storage chamber, and are connected with steady flow compensator by gas path pipe, and hydraulic pressure sensor and baroceptor are arranged on respectively on water cavity sealing plate and air cavity sealing plate; Packed-piston is arranged on water cavity sealing plate by packed-piston cover; Hydraulic pressure sensor and baroceptor are drawn outside sealing drum by holding wire.
By gas path pipe, packed-piston cover, ball float support, hydraulic pressure sensor is arranged on water cavity sealing plate, then water cavity sealing plate is welded on sealing drum, again baroceptor is arranged on air cavity sealing plate, air cavity sealing plate is welded on sealing drum, after holding wire is drawn outside sealing drum, will seal cover bolt fixes, ball float is welded on ball float support, finally sealing drum is welded on flange, during normal use, ball float is affected by gravity in lower position, make packed-piston in bottom, now air enters air storage chamber by packed-piston, then by gas path pipe, air is inputted in steady flow compensator, when water level soaked after ball float, ball float rises, by packed-piston jack-up, baroceptor, hydraulic pressure sensor feeds back to non-negative pressure water-supply installation by pressure signal, the operation of control appliance, after water level declines, packed-piston is opened automatically, now the air in steady flow compensator is by gas path pipe air storage chamber and sealing drum, avoided the appearance of vacuum.
As a kind of preferred version of the supporting vacuum eliminating device of non-negative pressure water-supply installation described in the utility model, described seal cover is fixed by set bolt and sealing drum.
Beneficial effect:
The steady flow compensator in non-negative pressure water-supply installation that can make the supporting vacuum eliminating device of non-negative pressure water-supply installation described in the utility model can realize the negative pressure appearance producing when eliminating and suppressing water pump operation, due to rational in infrastructure, reliable in action, rapid, air pressure, hydraulic signal can be sent to control appliance, the operation conditions of checkout equipment, this non-negative pressure water-supply installation matched with vacuum restraining device is simple in structure, not only with low cost, and technique is simple, the process-cycle is shorter.
Accompanying drawing explanation
Fig. 1 is the structural representation of the supporting vacuum eliminating device of non-negative pressure water-supply installation described in the utility model.
Wherein: 1, flange 2, sealing drum 3 hydraulic pressure sensor 4 water cavity sealing plates 5, baroceptor 6, air cavity sealing plate 7, holding wire 8, set bolt 9, seal cover 10, packed-piston cover 11, packed-piston 12, ball float support 13, ball float 14, gas path pipe
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the vacuum eliminating device that a kind of non-negative pressure water-supply installation is supporting, comprises flange 1, sealing drum 2, packed-piston 11, ball float 13, seal cover 9, and described ball float 13 is connected with water cavity sealing plate 4 by ball float support 12; The interior water cavity sealing plate 4 of sealing drum 2 and air cavity sealing plate 6 form an air storage chamber, and are connected with steady flow compensator by gas path pipe 14, and hydraulic pressure sensor 3 and baroceptor 5 are arranged on respectively on water cavity sealing plate 4 and air cavity sealing plate 6; Packed-piston 11 overlaps 10 by packed-piston and is arranged on water cavity sealing plate 4; Hydraulic pressure sensor 3 and baroceptor 5 are drawn outside sealing drum 2 by holding wire 7.
Although embodiment of the present utility model is illustrated in manual, these embodiments just, as prompting, should not limit protection domain of the present utility model.In the scope that does not depart from the utility model aim, carrying out various omissions, displacement and change all should be included in protection domain of the present utility model.
