Detail

A. Basic parameters:

1. The user types: industrial or civil

2. The gas delivery pressure: 0.2-0.4 MPa

3. CNG decompression sleds flow: 1000 Nm after/h

4. Double entry, single channel configuration, each secondary voltage regulation

5. Exit gas temperature 5 or higher


B. Decompression sleds performance

1, the design pressure

The design pressure before level 1 pressure regulating: 25.0 Mpa

The design pressure after level 1 pressure regulating: 1.5 Mpa

The design pressure after level 2 pressure regulating: 0.6 Mpa

2, operation pressure

Equipment inlet pressure: 20.0 Mpa

The pressure after level 1 pressure regulating: 0.8-0.8 Mpa

The pressure after level 2 pressure regulating: 0.2-0.2 Mpa

3, the choice of pressure regulating device

Primary and secondary voltage regulator selects the import high quality brand, guarantee  the equipment pressure and outlet pressure at various levels.


C. CNG station position of safety protection

Equipment safety protection chain including automatic cutting and automatic overpressure tossing, stepped double protection.

1, automatic cut off the chain

Control system to control the chain line, chain control points are as follows:

* The exit natural gas temperature of regulator station over low temperature limit

* The pressure after level 1 pressure regulating ultralimit

* The pressure after level 2 pressure regulating ultralimit

* The gas leakage alarm

When the above chain point to appear in any one or more, the way the entrance to the emergency cut-off valve shut automatically

Closed to protect downstream overall equipment;

2, ultrahigh pressure loss on its own

Safety relief pipe valve are set on the pipeline after per level pressure regulating, when the pressure over the set value after the level 1 pressure regulating, the primary radiation  valve automatically opens radiation; when the pressure over the set value after the level 2 pressure regulating, the secondary radiation valve automatically opens radiation.
