Description

Technical Field

[0001] The utility model relates to the technical field of distribution valves, in particular to a distribution valve with adjustable pressure. Background Art

[0002] With the continuous development of society, high-rise buildings, schools, factories and other places have a large demand for water, but there is often a phenomenon of no water. The reason for this phenomenon is not that the water pressure of the water supply unit is insufficient, but because there are too many people using water in these buildings and the water use is concentrated at a certain time, resulting in a drop in water pressure in the water-using areas. When the water cannot flow to the upper floors, it is easy to affect water use. Therefore, a distribution valve that can adjust the pressure was designed.

[0003] Announcement No. CN102720870B provides a water flow regulating distribution valve for high-rise building water supply and a method for regulating use. The pressure regulating spring is adjusted by a pressure regulating bolt so that the pressure value decreases with increasing floor level. A distribution valve is installed on the water supply pipe of each floor except the top floor, so that the opening degree of the distribution valve on each floor is consistent and the water supply flow rate is consistent. The advantages of the present invention are: simple structure, solving the problem that users on high floors cannot use water when the water pressure is too low, and can adjust the water flow rate of users on lower floors according to the changes in water pressure. When the water pressure is high and the water supply can reach the top floor of the building, all the distribution valves are in a fully open state and the flow rate of each floor is not restricted. When the water pressure is low and the water supply cannot reach the top floor of the building, the distribution valve reduces the water supply to each floor according to the water pressure, preventing the water pressure in the building from dropping too much and ensuring that users on each floor have water.

At this time, the lower end of the mounting cover 3 is in close contact with the sealing ring 2 to ensure a tight seal. When the distribution valve needs to be adjusted in pressure, water flows into the distribution valve body 1 from the left side, and the water pressure is relatively large, which drives the pressure balance membrane 15 to push up and squeeze the first spring 14. At this time, hold the handle 10 and slide it to the right side of the transmission rod 7, so that the fixing block on the right side of the handle 10 engages with the hole groove at the right end of the transmission rod 7.
