Problems solved by technology
[0003] During the use of the existing expansion tank, the gas inside the expansion tank will gradually overflow over time. When the gas inside the expansion tank is too small, the air pressure is not enough to balance the pressure of the water in the air bag, resulting in the failure of the expansion tank. It affects the normal use of the expansion tank, and the existing expansion tank cannot see whether the gas is sufficient, and can only be inflated at regular intervals based on experience, and the gas content inside the expansion tank cannot be controlled. For this reason, we provide a water network pressure compensation Diaphragm expansion tank

Embodiment Construction
[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.
[0024] see Figure 1 to Figure 5 , the present invention provides a technical solution: a diaphragm expansion tank for water network pressure compensation, including an expansion tank body 1, the expansion tank body 1 includes a metal layer 101, and an anti-corrosion layer 102 is provided on the outside of the metal layer 101 to prevent corrosion. The layer 102 is an epoxy resin layer, and the anti-corrosion layer 102 is provided with a waterproof layer 103 outside. The corrosion layer 102 can prevent the expansion tank 1 from being corroded and damaged during use, and the waterproof layer 103 can prevent the metal layer 101 and the anti-co...

The invention discloses a diaphragm expansion tank for water network pressure compensation, and relates to the technical field of expansion tanks, in particular to a diaphragm expansion tank for water network pressure compensation, comprising an expansion tank body, and an airbag is arranged inside the expansion tank body. A support plate is fixedly connected to the outside of the airbag, a support spring is fixedly connected to the outside of the support plate, a pressure sensor is arranged on the left side of the support spring, and an inflation and exhaust port is fixedly connected to the left side of the expansion tank. , and a pressure gauge is fixedly connected to the top of the expansion tank body. The diaphragm expansion tank for water network pressure compensation is used to balance the pressure formed by the expansion of the air bag by arranging a support spring outside the air bag, and using the support spring to support the support plate, so as to facilitate the air bag to be squeezed when the water network pressure becomes small. , the water inside the airbag is transported into the water network to avoid the pressure drop in the water network too fast, and solve the problem that the traditional expansion tube leaks too much gas and cannot compensate for the water pressure.
Description
technical field [0001] The invention relates to the technical field of expansion tanks, in particular to a diaphragm expansion tank for water network pressure compensation. Background technique [0002] The expansion tank is a kind of gas pressure in the expansion tank that is greater than the water pressure when the water loss pressure is reduced. At this time, the gas expansion squeezes the water in the air bag to the system. The working principle of the expansion tank: when the water under pressure from the outside enters When the expansion tank is in the airbag, the nitrogen sealed in the tank is compressed. According to Boyle's gas law, the volume of the gas becomes smaller after being compressed, and the pressure rises until the gas pressure in the expansion tank is consistent with the water pressure, and the water is stopped. When the water loss pressure is reduced, the gas pressure in the expansion tank is greater than the water pressure, and the gas expansion squeez...
