Water distribution gate valve

Water distribution gate valveIt is a valve used to control and regulate water flow, widely used in urban water supply, drainage, agricultural irrigation, industrial production and other fields. Its advantages lie in its simple structure, reliable sealing, and easy operation.

1. Control water flow rate

The water distribution gate valve can control the flow rate of water by adjusting its valve opening to change the cross-sectional area of the water flow in the pipeline.

2. Cut off the pipeline

In the maintenance, repair, and replacement of water pipelines, water distribution gate valves can cut off the water pipeline, thereby avoiding water flow into the pipeline and providing convenience for operation.

3. Prevent water hammer

Water hammer refers to the impact force that occurs when the water flow changes rapidly. Water distribution gate valves can reduce and eliminate water hammer by controlling the water flow rate in pipelines.

4. Protect pipelines and equipment

Water distribution gate valves can protect pipelines and equipment from damage caused by excessively high or low water flow pressure by regulating flow rate.

5. Energy conservation

By correctly setting and using the water distribution valve, the water level of the water pump can be lowered, thereby saving energy for the water pump.

Water distribution gate valves are widely used in urban water supply, drainage, agricultural irrigation, industrial production and other fields, playing an important role. Taking farmland irrigation as an example, the use of water distribution gate valves can achieve rural irrigation automation, improve water resource utilization, reduce energy consumption, and increase production efficiency. Therefore, the application of water distribution valves is not only to control and regulate water flow, but more importantly, to solve a series of problems in practical production and life, with extensive and profound application value.

Water distribution gate valveStructural Description

1. The water distribution gate valve consists of a control panel, connecting rod, valve stem, gate valve, short pipe and other components.

2. The PZ2 model uses a small electric motor as a power source to replace manual operation, which is convenient and fast.

3. A gate valve consists of a valve body and a valve disc.

(1) The gate body is a welded component, with a conical sealing ring installed at the lower part, which together with the valve disc forms the sealing part.

(2) The valve disc is composed of welded parts and rubber pads, and is connected to the valve stem through a ring screw assembly to ensure the sealing performance of the valve.

4. Short pipes are used to embed into the well walls of water distribution wells and are welded components.

5. The length of the connecting rod is determined by the height difference between the bottom plate of the water distribution well and the bottom plate of the pump room. It is divided into four specifications: 5 meters, 4.5 meters, 4 meters, and 3.5 meters. Users can also determine the length of the connecting rod according to the actual installation height and customize it as needed.
