Balancing control valve

Abstract

The invention belongs to accessory devices in the technical field of water heating equipment, and particularly relates to a balancing control valve. A valve body (1) is designed to be arranged on the balancing control valve, a piston part (2) is arranged in the valve body (1), and the piston part (2) makes corresponding displacement movement to achieve balancing in the valve body (1) along with the pressure change of the water outlet end of the control valve under the guiding action of the valve body (1) and a guide part (3). The limiting face (6) of the piston part is not limited to be in the graphical mode any more and also can be in other modes such as the discontinuous face, the slope, the square cross section, the circular cross section and the combining form of the discontinuous face, the slope, the square cross section and the circular cross section. The piston part (2) in the control valve is provided with one face, an angle beta is formed between the face and the axis of the piston part, and the beta is larger than zero degree and smaller than 90 degrees. When the face enables the piston part to make contact with a sealing gasket, the contact surface of the piston part and the sealing gasket is as smaller as possible, due to the fact that the contact area is decreased, the sealing reaction speed of the piston part is increased, and the performance of the control valve is improved.

Description

technical field [0001] The invention belongs to an accessory device in the technical field of plumbing equipment, and in particular relates to a balance control valve with stable performance and a new structure for prolonging the service life of the equipment. Background technique [0002] China is a large production and consumption country of control valves, balance control valves, traditional control valves pass through the water directly, without buffer balance control, when the pressure and flow of water change, no timely control is taken, when the water pressure exceeds the use of equipment At the rated pressure and rated flow rate, the equipment is often damaged or the pipeline is broken, which causes a great loss of manpower and material resources to the family or unit, and wastes a lot of precious water sources. Therefore, a new structure of the control valve is designed. When the water pressure reaches gradually When the set value is reached, the water inlet will be...

Problems solved by technology

[0002] China is a large production and consumption country of control valves, balance control valves, traditional control valves pass through the water directly, without buffer balance control, when the pressure and flow of water change, no timely control is taken, when the water pressure exceeds the use of equipment At the rated pressure and rated flow rate, the equipment is often damaged or the pipeline is broken, which causes a great loss of manpower and material resources to the family or unit, and wastes a lot of precious water sources. Therefore, a new structure of the control valve is designed. When the water pressure reaches gradually When the set value is reached, the water inlet will be automatically and gradually closed, so that families or units can use it with confidence, and will not worry about damaging the equipment due to changes in water pressure. In addition, using this new balance control valve can save water. Precious water saving today is the responsibility of each of us
