Description

an intermittent water supply system

technical field

The utility model belongs to the field of water supply treatment, in particular to an intermittent water supply system.

Background technique

As shown in Figure 1, a traditional intermittent water supply system includes a water storage tank 1, through which a water supply pump 2, an automatic valve 3, and corresponding water supply pipelines are laid to transport the water in the water storage tank to the water point. When the water point needs water, first start the water supply pump 2, and then open the automatic valve 3; when the water point does not need water, first close the automatic valve 3, and then stop the water supply pump 2. Since the water point is used intermittently, the water supply pump should be turned on or off according to the demand of the water point. When the water point frequently uses water intermittently, the water supply pump must also be started and stopped frequently. Frequent start and stop will affect the service life of the water supply pump. , The huge water flow impact at the moment of frequent start-up of the water supply pump will also damage the automatic valve.

Utility model content

In view of the above problems, the purpose of this utility model is to provide an intermittent water supply system, which aims to solve the technical problem in the existing water supply system that the water supply pump needs to be started and stopped frequently according to the water point, which affects the service life of the water supply pump and the automatic valve.

The utility model is achieved in this way. An intermittent water supply system includes a water storage tank, a water supply pump and an automatic valve. The water storage tank is connected to the water point through the water supply pump and the automatic valve in turn. The outlet of the water supply pump An overflow pipe is also connected between the end and the water storage tank, and the overflow pipe is provided with an overflow valve that is automatically opened or closed according to the water pressure in the overflow pipe.

Further, the inlet end of the water supply pump is connected to the bottom of the water storage tank through a pipeline.

Further, one end of the overflow pipe is connected to the outlet end of the water supply pump, and the other end is connected to the top of the water storage tank.

The beneficial effects of the utility model are: in the utility model, the overflow valve can be automatically opened or closed according to the water pressure in the overflow pipe, and the overflow valve is opened when the water pressure is high and closed when the water pressure is low; The water pump is in a continuous running state. When the water point needs water, the automatic valve opens. At this time, the water pressure in the overflow pipe is relatively low due to the pressure relief of the water supply pump. The normal water supply; when the water point does not need water, the automatic valve closes, at this time, due to the pressure of the water supply pump, the water pressure in the overflow pipe is relatively high, and the overflow valve will automatically open, so that the inlet and outlet pipes of the water supply pump Unblocked, the water supply pump can still work normally, so that the water supply pump can run continuously and realize intermittent water supply to the water point, avoid frequent start and stop of the water supply pump, and prolong the service life of the water supply pump and automatic valve.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

In order to illustrate the technical solution described in the utility model, the following specific examples will be used for illustration.

Fig. 2 shows the structure of the intermittent water supply system provided by the embodiment of the present invention, and only shows the parts related to the embodiment of the present invention for convenience of description.

The intermittent water supply system provided in this embodiment includes a water storage tank 1, a water supply pump 2 and an automatic valve 3. The water storage tank 1 is connected to the water point through the water supply pump 2 and the automatic valve 3 in turn. The water storage tank 1, The water supply pump 2, the automatic valve 3 and the water point are connected through pipelines, and an overflow pipe 4 is connected between the outlet end of the water supply pump 2 and the water storage tank 1, and the overflow pipe 4 is provided with a The overflow valve 5 that is automatically opened or closed by the water pressure in the overflow pipe. As a specific preferred embodiment, the inlet end of the water supply pump 2 is connected to the bottom of the water storage tank 1 through a pipeline. One end of the overflow pipe 4 is connected to the outlet of the water supply pump 2 , and the other end is connected to the top of the water storage tank 1 . It is more convenient for the water supply pump to set up like this.

The opening pressure and the closing pressure of the overflow valve 4 can be set and adjusted, so that the overflow valve opens when the water pressure in the overflow pipe is high and closes when it is low. When the water point needs water, the automatic valve 3 is opened. At this time, due to the pressure relief of the water supply pump 2, the water pressure in the overflow pipe 4 is relatively low, and the overflow valve 5 will automatically close, thereby ensuring the water supply pump 2 to the water point. Normal water supply; when the water point does not need water, the automatic valve 3 is closed, at this time, due to the pressure of the water supply pump 2, the water pressure in the overflow pipe 4 is relatively high, and the overflow valve 5 will automatically open, so that the water supply pump enters The outlet pipeline is unblocked, and the water supply pump can still work normally, and the water supply pump pumps out the water in the water storage tank and then injects it into the water storage tank. In this way, the water supply pump can be continuously operated to realize intermittent water supply to the water point.

In this implementation, when the water point needs water, the automatic valve opens, and the overflow valve closes to realize normal water supply. When the water point does not need water, the automatic valve closes, the overflow valve opens, and the water supply pump circulates water, so that the water supply pump is in continuous operation state, realize intermittent water supply to water points, avoid frequent start and stop of water supply pumps, and prolong the service life of water supply pumps and automatic valves.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
