TECHNICAL FIELD
[0001] The utility model belongs to the technical field of water supply and drainage system, more particularly to a kind of water hammer elimination tank for eliminating water hammer effect. BACKGROUND
[0002] In water supply and drainage pipeline system, when water pump is suddenly started, stopped or quickly regulated flow, the water flow velocity in pipeline can change sharply, thereby generating water hammer phenomenon. The instantaneous high pressure generated by water hammer can cause serious damage to pipeline, valve, water pump and other equipment, such as pipeline rupture, valve seal failure, water pump impeller damage, etc., which can also affect the stability and safety of the whole system, reduce the service life of the system, increase maintenance cost and operation risk. Traditional water hammer elimination method has many limitations, for example, ordinary check valve can only prevent backflow, and cannot effectively eliminate water hammer pressure. Some buffer type water hammer elimination devices have complex structure, large size, unsatisfactory hammer elimination effect and high cost. Therefore, it is of great practical significance to develop a kind of water hammer elimination tank which is efficient, reliable, simple in structure and low in cost. SUMMARY
[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art, and to provide a kind of water hammer elimination tank for eliminating water hammer effect.
[0004] The technical scheme adopted to solve the above technical problems is: a kind of water hammer elimination tank for eliminating water hammer effect, including connecting pipeline, the inside of connecting pipeline is installed with tank body, the top of tank body is connected with inlet valve and exhaust valve, the top end of tank body inner wall is installed with pressure sensor, the inside of tank body is provided with air bag, installation cavity is set up in the inside top of tank body, electric control assembly is installed in the inside of installation cavity, electric control assembly is electrically connected with inlet valve, exhaust valve and pressure sensor.
[0005] Further, the air bag is communicated with the exhaust valve and the inlet valve, so that the air pressure in the air bag can be controlled through the inlet valve and the exhaust valve in combination with the use of the pressure sensor.
[0006] Further, the bottom end of the tank body is in the form of a hemisphere with a cavity inside, and the spherical shape is selected to allow the air bag to expand as much as possible to conform to the inner wall of the tank body after inflation, so that the pressure sensor can monitor the change of air pressure in the air bag.
[0007] Further, the inlet valve and the exhaust valve extend to the outside of the connecting pipeline, and an opening corresponding to the position of the tank body is formed in the top of the connecting pipeline to facilitate the connection of the air pipe with the exhaust valve and the inlet valve from the outside.
[0008] Furthermore, the ends of the first and second telescopic rods that are furthest from each other are hinged to the outer surface of the third telescopic rod. Through the above connection method, a near-triangular frame structure is formed between the three telescopic rods and the arc-shaped spring sheet, which improves the structural strength between the telescopic rods and the arc-shaped spring sheet.
[0009] Furthermore, a spring is sleeved on the outer surface of the third telescopic rod, and limit blocks are provided at both ends of the spring. Through the cooperation between the limit blocks and the spring, the telescopic rod can be reset by means of elastic force after being compressed by pressure.
[0010] The beneficial effects of this utility model are as follows: This utility model utilizes a water hammer elimination tank, mainly composed of a tank body, an air bladder, an inlet valve, an exhaust valve, a pressure sensor, and connecting pipes. The air bladder is installed inside the tank, and the gas pressure inside the air bladder is controlled by the inlet and exhaust valves. During normal operation, the air bladder is filled with gas at a certain pressure. When water hammer occurs, the pressure inside the pipe increases sharply, and the water flow impacts the tank body, compressing the air bladder inside the tank, reducing the gas volume, and increasing the pressure, thereby absorbing the energy generated by the water hammer and reducing the peak water hammer pressure. The pressure sensor is installed inside the tank to monitor the pressure changes in the pipe in real time and transmits the signal to the electronic control component. When the pressure exceeds a set threshold, the electronic control component can automatically adjust the inlet or exhaust valve to optimize the buffering effect of the air bladder.
