Abstract
The utility model discloses a non-contamination, no-negative-pressure water supply equipment, which comprises a steady-flow tank and a pump. An inlet connected with tap water pipe is arranged on the top of the steady-flow tank. An outlet connected with the pump is positioned at the bottom of the steady-flow tank. A pressure gauge and a vent valve are arranged on the steady-flow tank. The piston plates are positioned at the two ends of the steady-flow tank symmetrically, which are hermetic-arranged with the inner circle of the steady-flow tank. The hermetic room between the piston plates and the two ends of the steady-flow tank communicates with the vent valve. Thus air and water are separated inside the steady-flow tank by the application of the piston plates in the utility model. When water runs into the steady-flow tank from tap water pipe, the piston plates move back towards the end and air is exhausted, and when the pump pumps, the water in the steady-flow tank decreases, the piston plates move forward and air is replenished, so as to adjust the air pressure in the tank to meet the requirement of water supply. As the air can be replenished in time automatically, the air negative pressure in the tank is eliminated. Furthermore, the secondary contamination can be effectively avoided.
Description
Technical field
The utility model relates to a kind of water supply installation.
Background technology
Water pump directly is installed on the public water supply pipeline of city is drawn water and can cause the excessively suction and produce negative pressure of tap water pipe network, thereby influence other user's water, the serious pipe network that also may cause damages.In addition, because gas-vapor mix in a body, forms secondary pollution easily.
The utility model content
At the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of pollution-free, non-negative pressure water-supply installation, and make up air is eliminated negative pressure, and avoided secondary pollution automatically.
For achieving the above object, a kind of pollution-free, non-negative pressure water-supply installation of the utility model comprises: current stabilization jar and water pump, the top of current stabilization jar is provided with water inlet, the bottom is provided with delivery port, water inlet links to each other with running water pipe, delivery port links to each other with described water pump, described current stabilization jar is provided with pressure meter and outlet valve, the interior two ends of described current stabilization jar are symmetrically arranged with the piston plate with current stabilization jar inner peripheral surface air-tight fit, space and the airtight conducting of described outlet valve between piston plate and the described current stabilization jar two ends.
Further, also be provided with liquid level sensor in the described current stabilization jar.
The utility model is by being provided with piston plate, make air and moisture from, piston plate retraction exhaust when pipe network comes water, when starting mode of pump draw water make jar in during the water minimizing, press tonifying Qi in jar simultaneously before the piston plate, played the requirement that the regulating tank internal pressure reaches water supply, can be in time make up air automatically, eliminate negative pressure, and can avoid secondary pollution effectively.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment:
As shown in drawings, the utility model comprises: current stabilization jar 1 and water pump 6, the top of current stabilization jar 1 is provided with water inlet 8, the bottom is provided with delivery port 9, water inlet 8 links to each other with running water pipe 10, delivery port 9 links to each other with water pump 6, current stabilization jar 1 is provided with pressure meter 5 and outlet valve 2, current stabilization jar 1 interior two ends are symmetrically arranged with the piston plate 3 with current stabilization jar 1 inner peripheral surface air-tight fit, space between piston plate 3 and current stabilization jar 1 two ends and outlet valve 2 airtight conductings, piston plate 3 is set, make air and moisture from, piston plate 3 retraction exhausts when pipe network comes water, when starting mode of pump draws water when making current stabilization jar 1 in the water minimizing, press tonifying Qi in current stabilization jar 1 simultaneously before the piston plate 3, played and regulated the requirement that current stabilization jar internal pressure reaches water supply.In addition, also be provided with liquid level sensor 4 in the current stabilization jar 1, be used for the height of sensed water level.
