Overview

Pressure regulating valve is a key equipment in the water supply system of water plants, used to control and regulate the water pressure in pipelines, ensuring the safe and stable operation of the water supply system.

Product Details

1、 Basic functions and roles of pressure regulating valves in water plants

1. Pressure regulation: Automatically reduce upstream high pressure to the stable low pressure required downstream, or maintain a specific pressure level

2. Safety protection: prevent pipeline bursting and equipment damage caused by overpressure in the pipeline network

3. Flow control: Indirectly control the distribution of water flow through pressure regulation

4. Energy saving and consumption reduction: Reduce unnecessary pressure loss and lower water pump energy consumption

2、 Common types of pressure regulating valves used in water plants

1. Pilot operated pressure regulating valve:

Using a pilot valve to control the action of the main valve

High adjustment accuracy, suitable for high flow situations

Typical application: Pressure control of main pipelines in water plants

2. Direct acting pressure regulating valve:

Simple structure and easy maintenance

Suitable for low flow and medium low pressure applications

Typical application: Pressure regulation of branch pipeline network

3. Electric pressure regulating valve:

Accurate control through electric actuators

Can be integrated with SCADA system to achieve remote control

Typical application: Modern water plants with high degree of automation

4. Pneumatic pressure regulating valve:

Using compressed air as a power source

Good explosion-proof performance, suitable for special environments

Typical application: Water supply system for flammable and explosive areas

3、 Factors to Consider in the Selection of Pressure Regulating Valves

1. System parameters: working pressure, flow range, medium temperature, and water quality characteristics

2. Control requirements: adjustment accuracy, response speed, degree of automation

3. Installation environment: Space limitations, explosion-proof requirements, corrosive environment

4. Maintenance requirements: frequency of replacement of vulnerable parts, convenience of maintenance

5. Economic factors: Balance between initial investment costs and long-term operation and maintenance costs
