As shown in fig. 1 and 2, the following technical solutions are adopted in the present embodiment: the device comprises a tank body 1, a base 2, a water inlet flange 3, a lifting lug 4, a standby interface 5, a lower breathing type vacuum suppressor 6, a water shortage protection device 7 and a water outlet flange 8; the bottom fixed mounting of the jar body 1 has base 2, the inlet tube has been seted up to the upper end of the jar body 1, fixed mounting has inlet flange 3 on the inlet tube, fixed mounting has lug 4 on the last lateral wall of the jar body 1, reserve interface 5 has been seted up at the upper end middle part of the jar body 1, the upper right end fixed mounting of the jar body 1 has lower breathing type vacuum suppressor 6, the installing port has been seted up to the left downside of the jar body 1, fixed mounting has water shortage protection device 7 on the installing port, the bottom fixed mounting of the jar body 1 has outlet pipe and blow off pipe, fixed mounting has outlet flange 8 on the outlet pipe, fixed mounting has blow off flange 9 on.
Furthermore, a nameplate is bonded on the tank body 1.
Further, the spare interface 5 is an internal wire of G1/2.
The working principle of the specific embodiment is as follows: the core component for eliminating negative pressure of the non-negative pressure tank is a vacuum eliminator; when not filling water in the jar, the vacuum eliminator is in the open mode, and jar non-confined state this moment, when in the running water injection flow stationary flow jar, the air in the jar alright discharge in the vacuum eliminator, treat that water is full of the back, the floater couples gradually with the sealing washer of vacuum eliminator, and final vacuum eliminator just is in the closed condition, is in isolated encapsulated situation completely with the external world in the jar this moment. If the municipal water supply is sufficient all the time, the vacuum eliminator is in a closed state all the time, the municipal pipeline pressure is transmitted into the pump for pressurization again, and the steady flow tank achieves the effect of fully utilizing the municipal pipe network pressure; if the water consumption peak period leads to the pump to pump the water yield and slightly be greater than under the municipal water supply (simply say and draw inadequately) the condition, the water level in the jar can descend, and the sealed spheroid of vacuum eliminator also can descend, and vacuum eliminator is in the open mode this moment, and external air gets into the regulation jar by vacuum eliminator, has stopped to draw water the time and has led to the negative pressure to produce because the water supply is not enough. The negative pressure can be eliminated without negative pressure. When municipal administration is completely cut off water, the built-in liquid level detector of no negative pressure tank transmits the water shortage signal to the equipment control box, and the effect of water shortage protection can be played.
In this embodiment, the tank body is made of 304 stainless steel (except 201 adopted by the base), the vacuum suppressor is installed on the upper part of the tank body, the upper part of the tank body is provided with a mounting hole for protecting the collection device from water shortage, and the lower part of the tank body is a joint of a water outlet pipeline and is provided with a drain valve. The non-negative pressure steady flow tank is used for storing a small amount of water and eliminating the potential vacuum generation possibility in combination with the constant pressure water supply equipment.
The components of the present embodiment mainly function: a stainless steel tank body: storing water to form a closed space; a vacuum suppressor: and the vacuum in the tank is eliminated by matching with the stainless steel tank body.
The beneficial effect of this embodiment does:
① when the inlet valve is opened, the pressure of the municipal pipe network can be partially eliminated by the arc structure of the inner wall of the device;
② when water is increased, the air in the tank can be exhausted from the vacuum eliminator, and the vacuum eliminator is closed, and the tank and the outside are completely sealed;
③ if the municipal water supply is sufficient, the vacuum eliminator is in a closed state all the time, the municipal pipeline pressure is transmitted to the pump for pressurization again, and the steady flow tank achieves the effect of fully utilizing the municipal pipeline pressure;
④ if the municipal water supply is insufficient, the vacuum eliminator is in open state, and the outside air enters the adjusting tank through the vacuum eliminator, thereby avoiding negative pressure generation caused by insufficient water supply during water pumping.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
