Environment-friendly high-rise building constant-pressure secondary water supply device

Abstract

The invention discloses an environment-friendly high-rise building constant-pressure secondary water supply device. The device comprises a high-rise water storage tank, a sealing tank cover and a pressure intensity balancing mechanism, wherein the sealing tank cover is detachably mounted at the top of the high-rise water storage tank, and the pressure intensity balancing mechanism is arranged in the middle of an inner cavity of the high-rise water storage tank. Through cooperative use of the sealing tank cover, an exchange sealing table, a reset strong spring, a pressure control corrugated pipe and a compression deformation sleeve, when water is stored in the inner cavity of the high-rise water storage tank and gradually pumped and conveyed, the exchange sealing table can continuously descend along with descending of the water level in the water tank and gradually extrude the compression deformation sleeve, so that in the water pumping process, pressure intensity balance in the water tank is kept under the condition that no external air enters the water tank and secondary pollution is caused, and normal water pumping work of a pressurizing water pump is guaranteed.

Description

technical field [0001] The invention relates to the technical field of secondary water supply equipment, in particular to an environment-friendly constant-pressure secondary water supply device for high-rise buildings. Background technique [0002] Secondary water supply means that units or individuals store and pressurize urban public water supply or water supply from self-built facilities for users to use through pipelines. For high-rise buildings, due to the lack of pressure in the municipal water supply pipeline, it is usually necessary to pressurize the municipal water supply twice to make the tap water reach the high-rise and be used by high-rise users; the existing secondary water supply method usually includes adding a high-pressure pump directly in the middle of the floor , or design a reservoir on the roof of a high-rise building, and pump water into the reservoir in advance before use for users to use. However, after the storage tank has been used for a long time...

Problems solved by technology

However, after the storage tank has been used for a long time, it will usually cause a large number of bacteria to grow, and the large amount of bacteria will have a great impact on the human body. Therefore, after tap water is pumped into the storage tank, it will usually be disinfected first before being used for users. use

[0003] At present, among the equipment used for secondary water supply, the key is the water storage equipment and the equipment used for pressurization. Among them, the pressurization equipment currently used is also relatively common, and it is mainly for the pressurization operation of the water delivery pipeline. , the pressurized water pump is used for the delivery operation, and the pressurized water pump is connected to the water outlet of the water tank through a pipeline, but the water storage equipment is generally designed with a water tank installed on the roof of a high-rise building, and it is the most common at present The most important thing is to place it in an open-air environment. Although the tap water is sterilized by various agents before use, the bacteria and microorganisms that grow in the water pipes and the microorganisms that grow in the water tank will and bacteria are also unavoidable; and because the water tank is full of water, and its inner cavity is in a dark environment for a long time, it is more conducive to the growth of microorganisms and bacteria, and the pressure inside the water tank is constant all year round. The important function is to store tap water, and it has no other functions. When performing secondary water supply, it completely relies on the function of the pressurized water pump to cooperate with the use to achieve the purpose of boosting. When pumping tap water, the internal pressure of the water tank is completely self-adaptive. External pressure changes. This feature makes some sediment inside the tap water be drawn away when tap water is pumped, and enters the user's home along the water pipe. At the same time, outside air enters during the process of continuous ventilation and water addition. cause secondary pollution

At present, in order to prevent the sediment from being sent to the user's home, the filter screen design is often used, but long-term use will still cause the filter screen to be blocked and affect the normal water delivery work
