Problems solved by technology

The designer of the present invention found that according to the structure of the existing air pressure tank, when the water in and out of the air pressure tank is less, only the water in the air pressure tank near the water inlet and outlet can exchange with the water in the water supply pipe. Most of the water in the tank cannot be replaced for a long time to form stagnant water. The stagnant water that stays for too long is likely to breed microorganisms, make the water corrupt and deteriorate, and cause secondary pollution to the water

Embodiment 1

[0052] Example 1, see figure 2 .

[0053] This embodiment provides a bladder-type air tank used for domestic drinking water pressurization equipment, including a tank body 101, a rubber air bag 102 and a water inlet and outlet structure.

[0054] The rubber air bag 102 is arranged in the tank body 101 and divides the inside of the tank body 101 into an air chamber 103 and a water chamber 104 . The air chamber 103 is located between the outer wall of the rubber air bag 102 and the inner wall of the tank body 101 , and the water chamber 104 is located in the rubber air bag 102 . The tank body 101 is cylindrical, and the axis line of the tank body 101 is arranged vertically. The top and bottom of the tank body 101 are the upper head and the lower head respectively, and the upper head and the lower head are respectively provided with gas filling ports. 105 and the water inlet and outlet 106, the gas filling port 105 and the water inlet and outlet 106 communicate with the air ch...

Embodiment 2

[0064] Example 2, see Figure 3 ~ Figure 5 .

[0065] This embodiment provides a bladder-type air tank for domestic water delivery pipelines. Compared with Embodiment 1, this embodiment only improves the water inlet pipe 107. For other parts not mentioned in this embodiment, please refer to Example 1.

[0066] In this embodiment, the water outlet end of the water inlet pipe 107 is connected with a water outlet cover 118 , and the middle part of the water outlet cover 118 protrudes away from the water inlet pipe 107 and forms an arc surface. The ratio of the raised height of the water outlet cover 118 to the radius of the water inlet pipe is 0.5˜2:1, preferably 1:1. A plurality of first water outlet holes 119 are disposed on the water outlet cover 118 , and a plurality of first water outlet holes 116 are arranged along a circumferential direction of the water outlet cover 118 . The water outlet end of the water inlet pipe 107 is provided with a plurality of second water outl...

Abstract

The invention provides a bag-type air-pressure tank used for domestic drinking water pressurization equipment, and relates to the technical field of water supplying equipment. The bag-type air-pressure tank comprises a tank body, an elastic air bag is arranged inside the tank body, the interior of the tank body is divided into an air chamber and a water chamber through the elastic air bag, and an air adding opening and a water inflow and outflow opening are formed in the tank body, wherein the air adding opening is communicated with the air chamber, and the water inflow and outflow opening is communicated with the water chamber. A water inflow and outflow structure is arranged at the water inflow and outflow opening and comprises a water inlet pipe, a water outlet pipe and a seal shell, wherein the interior of the seal shell is communicated with the water chamber, the water outlet pipe is communicated with the interior of the seal shell, the water inlet pipe penetrates through the seal shell and extends into the water chamber, and the water outlet end of the water inlet pipe is away from the water inflow and outflow opening. The bag-type air-pressure tank used for the domestic drinking water pressurization equipment is connected with a water supply pipe in series, water inside the water supply pipe has to pass through the water chamber, water inside the water chamber can be effectively replaced whether the water pressure inside the water supply pipe fluctuates or not, dead water will not be formed inside the water chamber, microorganisms will not be generated inside the water chamber, and secondary pollution will not be generated.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to a bladder type air pressure tank used for domestic drinking water pressurization equipment. Background technique [0002] The pressure tank is the prerequisite for the water pump to go to sleep. Using the extremely small compressibility of water, the water is stored in the tank by external force. The gas is compressed and the pressure increases. When the external force disappears, the compressed gas expands and the water can be discharged. Since the compression ratio of water is much smaller than that of gas, when there is a small flow leakage in the pipe network, the pressure will drop significantly, which will cause the water pump to start frequently. [0003] When water with pressure from the outside enters the air bag of the air pressure tank, the nitrogen sealed in the tank is compressed. According to Boyle's gas law, the volume of the gas becomes smaller afte...
