Water-hammer arresting position control valve without frequent movement, and mounting method and position control method thereof

Abstract

The invention discloses a water-hammer arresting position control valve without frequent movement, and a mounting method and a position control method thereof, and belongs to the field of water supplypipe network water pressure control. As the control end of the water-hammer arresting position control valve communicates with a highest water level and a lowest water level, the facts that a valve body is opened and water enters a water tank only when the water level in a water tank is lower than a water release pipe, the valve body is closed and water stops entering the water tank only when thewater level in the water tank is higher than the highest water level, and the valve body does not move when the water level is positioned between the lowest water level and the highest water level are ensured, frequent opening and closing of the valve body can be prevented during water level control, and impact to a valve structure by frequent movement of the valve is eliminated. The water-hammerarresting position control valve has the advantages that the service life is longer, the valve is more difficult to damage, meanwhile occurrence of a pipeline water hammer is avoided, and the valve is beneficial to the safety of pipeline water supply systems.

Description

technical field [0001] The invention belongs to the field of water pressure control of a water supply pipe network, and in particular relates to a non-frequency-moving anti-hammer position control valve, an installation method and a position control method thereof. Background technique [0002] Existing hydraulic water level control valves are widely used on pools in water supply systems and water pipelines to control the water level of the pool and avoid pool overflow. However, in practice, it has been found that the hydraulic water level control valve has the problem of frequent opening and closing during the working process of controlling the water level, which causes severe pressure fluctuations in the pipeline and has a negative impact on pipeline safety. , resulting in many failures of the valve system as a whole, and eventually causing the pool to overflow and flood the work area. Therefore, a safer water level control device is urgently needed for the water supply n...
