Description
Technical Field
[0001] The utility model relates to the technical field of air pressure tanks, in particular to a novel diaphragm air pressure tank. Background Art
[0002] Diaphragm pressure tank is a kind of pressure tank. It is widely used in central air conditioning circulating water pressure stabilization, steam water supply expansion system, heating system circulating water replenishment pressure stabilization, fire water supply system replenishment pressure stabilization, variable frequency water supply pressure stabilization, boiler replenishment, pneumatic water supply and other occasions. In fact, it is an energy storage device composed of a steel shell and a rubber diaphragm liner. The rubber diaphragm completely separates the water chamber and the air chamber. When pressurized water from the outside is filled into the liner of the diaphragm pressure water tank, the air 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 increases to store energy. The expansion of the compressed gas can press the water in the rubber diaphragm out of the tank.
[0003] Under high pressure, the existing diaphragm pressure tank will generate a large impact pressure when the water in the tank is pressed out into the pipeline. The long-term pressure shock of water pressure and air pressure will cause the diaphragm liner to rupture and reduce the service life.
[0004] After searching the existing Chinese patent: a diaphragm air pressure tank (publication number: CN219933736U), the beneficial effect of the utility model is that the utility model is provided with a diaphragm structure on the inner wall of the capsule tank to ensure that water does not contact the inner wall of the capsule tank, so the inner wall of the capsule tank cannot be corroded, the service life is greatly extended, and the diaphragm structure effectively smoothes the pressure fluctuation in the water system and reduces the start and stop frequency of the water pump.
[0005] Although the above-mentioned Chinese patent has achieved the goal of preventing the capsule can from contacting water, the difference between the temperature in the water and the temperature outside will cause water vapor to form on the capsule wall, which will still affect the interior of the can and cause erosion over a long period of time.
[0006] Therefore, it is necessary to invent a novel diaphragm type air pressure tank to solve the above problems. Utility Model Content
[0007] The technical problem solved by the utility model is to provide a new type of diaphragm air pressure tank which is highly practical, can be simply operated and has a relatively simple structure. It solves the problem proposed in the above background technology that the temperature difference will cause water to produce water vapor, and when the water pressure is too high, the bladder will contact the tank wall and cause erosion.
[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: a new diaphragm air pressure tank, including a tank body, three buffer components are fixedly connected to the bottom surface of the tank body, the bottom of the tank body is connected with a drainage flange A, the bottom surface of the flange A is screwed and threadedly connected with a drainage component, a filter component and a diaphragm component, the inner wall of the tank body is fixedly connected with an insulation component, the surface of the insulation component is fixedly connected with an anti-corrosion layer, one side of the tank body surface is connected with an air inlet pipe, the top surface of the tank body is fixedly connected with a flange interface, the top surface of the flange interface is screwed and threadedly connected with a flange cover, and the edge of the top of the tank body is fixedly connected with a pressure gauge.

[0010] As a further solution of the utility model, the filter assembly includes a filter screen connected to the bottom surface of the flange A by screw threads, and an activated carbon layer is fixedly connected to the inside of the filter screen. The activated carbon layer is convenient for absorbing large particles of impurities in the water to prevent them from entering the diaphragm bag.
[0011] As a further solution of the utility model, the diaphragm assembly includes a diaphragm tube which is threadably connected to the bottom surface of flange A, one end of the diaphragm tube is fixedly connected with three layers of diaphragm bags, the surface of the third layer of the diaphragm bag is fixedly connected with an anti-rust layer, and the three diaphragm bags are arranged inside the tank body. The diaphragm bags are convenient for separating the tank body into an air chamber and a water chamber so that they are not connected to each other.
[0012] As a further solution of the utility model, the thermal insulation component includes a glass fiber layer fixedly connected to the inner wall of the tank body, and a rock wool layer is fixedly connected to the interior of the glass fiber layer, so that the rock wool layer can provide thermal insulation.
[0013] As a further solution of the utility model, the surface of the flange interface and the bottom surface of the flange cover are both provided with grooves, and a sealing gasket is clamped inside the groove, so that the sealing gasket is convenient for improving the sealing performance of the tank body.
[0014] As a further solution of the utility model, the drainage assembly includes a flange B which is threadedly connected to the bottom surface of the flange A, and the bottom end of the flange B is connected with a drainage pipe which facilitates the inflow and outflow of water.
[0015] The utility model provides a novel diaphragm type air pressure tank, which has the following beneficial effects:
[0016] 1. This new diaphragm pressure tank, through the setting of the diaphragm assembly, when in use, water will enter the diaphragm bag under pressure. The three-layer diaphragm bag increases the pressure resistance and bearing capacity of the pressure tank. The diaphragm bags of different levels can share the force when under pressure, reducing the impact of pressure on a single diaphragm bag, improving the safety and stability of the tank body, and avoiding the failure of the entire pressure tank due to conventional wear or damage of a single-layer diaphragm bag. With the three-layer design, even if one layer of the diaphragm bag is damaged, the diaphragm bags of other layers can still continue to play the role of isolation and protection, thereby increasing the service life of the pressure tank and reducing maintenance costs.
[0017] 2. The new diaphragm pressure tank is provided with a heat preservation component. During use, the glass fiber layer and the rock wool layer are high-quality heat preservation materials, which can effectively insulate and keep warm, thus reducing the loss of heat energy, stabilizing the temperature inside the pressure tank, improving thermal efficiency, and preventing water from rushing into the diaphragm bag under pressure. The water will form a difference with the air temperature outside the tank body, forming water vapor. Under the water pressure, the tank wall will be eroded by water over time, causing rust and reducing the service life. With the functions of the glass fiber layer and the rock wool layer, condensation on the inner wall of the tank body is prevented, the frequency of cleaning and maintenance is reduced, the operating efficiency is improved, and the formation of thermal stress is reduced, thereby reducing the risk of damage and fracture of the inner wall of the tank body and improving the safety of the tank body.
[0018] 3. The new diaphragm pressure tank is equipped with a filter assembly. When the water contains large particles, the water is pressed into the diaphragm capsule. After filtering and adsorbing by the filter net and the activated carbon layer, the large particles entering the diaphragm capsule are reduced, and the wear and damage to the diaphragm capsule are reduced. This can extend the service life of the diaphragm capsule, reduce the frequency of maintenance and replacement, and improve the reliability and economy of the pressure tank.
