Abstract
The utility model relates to a novel negative pressure eliminating device of a negative pressure less steady flow tank, which comprises a diaphragm tank. The utility model is characterized in that the outlet position of the diaphragm tank is provided with a cylinder body connected with the steady flow tank, and a rubber bag is arranged in the diaphragm tank. An outlet of the rubber bag is connected with a piston which is positioned in the cylinder body. The lower part of the cylinder body is provided with an air sucking and exhausting opening, and the outlet end of the cylinder body is provided with a baffle plate. The utility model has the advantage that the utility model can avoid the outside air being led into the steady flow tank and prevent the supplied water from being polluted.
Description
Technical field
The utility model relates to a kind of elimination negative pressure device, and particularly a kind of novel non-negative pressure current stabilization jar is eliminated negative pressure device.
Background technology
Vacuum cancellation element on non-negative pressure stabilized jar on the non negative pressure steady flow automatic water supply equipment generally adopts vacuum breaker now at present, when the pressure in the current stabilization jar is higher than atmospheric pressure, air in the current stabilization jar is just discharged by vacuum breaker, arranged until air, but water can not overflow; When the pressure in the current stabilization jar was lower than atmospheric pressure, the outer air of current stabilization jar just sucked by vacuum breaker.Because non-negative pressure water-supply installation adopts the current stabilization jar to reach the elimination negative pressure, avoid pollution because of adopting the pond to bring, but because vacuum breaker is introduced the air in the external world in the current stabilization jar, thereby the water quality of drinking water is degenerated, in addition because the introducing of extraneous air, easily make fouling on the current stabilization jar inwall, cause the decline of the quality of water supply of non negative pressure steady flow automatic water supply equipment.
Summary of the invention
The purpose of this utility model is that non-negative pressure stabilized jar on the non negative pressure steady flow automatic water supply equipment introduced existing problem in the current stabilization jar with the air in the external world in the solution prior art when eliminating negative pressure, and a kind of novel non-negative pressure current stabilization jar elimination negative pressure device that can avoid outside air to introduce the current stabilization jar is provided.The utility model designs a kind of novel non-negative pressure current stabilization jar and eliminates negative pressure device, comprise the barrier film jar, it is characterized in that: one cylinder body is arranged in the exit of barrier film jar, cylinder body connects the current stabilization jar, a capsule is arranged in the barrier film jar, and the outlet of capsule is connected with piston, and piston is positioned at cylinder body, in the bottom of cylinder body one suction and exhaust ports is arranged, on the port of export of cylinder body, plate washer is arranged.The utility model has the advantages that and to avoid outside air to introduce the current stabilization jar, prevent that the water of being supplied from being polluted.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is the structural representation that is connected on the current stabilization jar of the present utility model,
The specific embodiment
Comprise barrier film jar 1 among the figure, it is characterized in that: a cylinder body 2 is arranged in the exit of barrier film jar 1, cylinder body 2 connects current stabilization jar 3, a capsule 4 is arranged in barrier film jar 1, the outlet of capsule 4 is connected with piston 5, piston 5 is positioned at cylinder body 2, and a suction and exhaust ports 6 is arranged in the bottom of cylinder body 2, and plate washer 7 is arranged on the port of export of cylinder body 2.When the inflow of the water inlet 8 of current stabilization jar 3 during greater than the displacement of delivery port 9, pressure in the current stabilization jar 3 can rise, gas in the current stabilization jar 3 enters in the capsule 4 in the barrier film jar 1 by suction and exhaust ports 6, capsule 4 expands with equilibrium pressure, along with the water level in the current stabilization jar 3 rises, until piston 5 being pushed up to cylinder body 2 tops, at this moment water just can not enter in the barrier film jar 1; When the inflow of the water inlet 8 of current stabilization jar 3 during less than the displacement of delivery port 9, pressure in the current stabilization jar 3 can descend, piston 5 is to lower slider, slide into the lower end of suction and exhaust ports 6 when piston 5 after, be expelled in the current stabilization jar 3 by suction and exhaust ports 6 capsule 4 of gas in the current stabilization jar 3 in barrier film jar 1, capsule 4 dwindles with equilibrium pressure simultaneously, along with the drawdown in the current stabilization jar 3, gas in the barrier film jar 1 continuously outflows, be compressed to minimum volume until capsule 4, do not produce negative pressure in the current stabilization jar 3 to keep.
