Pressure Regulator Unit

Compressed natural gas is the wellhead natural gas or pipeline natural gas purification compressed high pressure storage and transportation, to use the location, after multi-level heat transfer, pressure regulation, measurement, and finally for customers to use.

Product Details

Introduction of Pressure regulator unit and Functional Principle

First, the Pressure regulator unit pipeline part of the introduction

1, the working principle

Compressed natural gas is the wellhead natural gas or pipeline natural gas purification compressed high pressure storage and transportation, to use the location, after multi-level heat transfer, pressure regulation, measurement, and finally for customers to use.

2, technical parameters (for reference only, subject to the actual requirements of customers)

1) Flow rate: 50 ~ 5000Nm³ / h;

2) structure: two imports, one after another, 3000Nm³ / h above the general for more than 3 parallel;

3) Ambient temperature: -20 ~ 60 ;

4) Working medium: CNG (compressed natural gas);

5) intake pressure: 22MPa (maximum allowable inlet pressure 22MPa);

6) export pressure: 0.1 ~ 0.4MPa (according to the actual requirements of customers to adjust);

7) intake air temperature range: -20 ~ 40 ;

8) outlet temperature range: 5 .

3, process introduction

High-pressure natural gas transported by CNG vehicles through the exhaust device, first into the heat transfer regulator system, in the regulator heat transfer system after two (or once) heat transfer, two (or three) voltage regulator, and then enter Metering system, odor system (according to the actual requirements of customers and the use of conditions to selectively install the environment) directly to the customer delivery. According to the regulator mechanism can be divided into two stages pressure regulator and three stages pressure regulator two modes. The pressure regulator is as follows:

1) two stages pressure regulator technology Description: First, high pressure hose and quick connector and CNG car connection, compressed natural gas through the high pressure ball valve, high pressure emergency shut-off valve, filter into a heat exchanger, in a heat exchanger Inside the gas for the first time heating, after a pressure regulator to 1.0-4.0MPa. And then into the secondary heat exchanger heating, after a two-stage regulator to 0.1-0.4 MPa, then enter the flow meter for volume measurement. And then through the natural gas to add odor (according to the actual requirements of customers and the use of conditions to selectively install the environment), and finally for customers to use. CNG regulator station natural gas medium pressure, temperature, flow, circulating hot water temperature display and control, import emergency shut-off valve control by the central console for chain control (if the PLC system, by the PLC system control).

2) Three stages pressure regulator technology Description: Compressed natural gas through the two-stage heat exchanger, but the regulator design for the three, under normal circumstances, after a pressure regulator is 1.0-4.0 MPa, two pressure regulator Is 0.1-0.4MPa. Three-stage pressure regulator is 5-50 KPa. And then through the flow meter, the gas on the odor (according to the actual requirements of customers and the use of conditions to selectively install the environment), and finally for customers to use.

4, the main structure (for reference only to the actual requirements of the customer)

1) Air discharge column: high pressure welding ball valve, (check valve), high pressure hose;

2) filter device: high pressure filter, low pressure filter;
