1. Installation requirements for gas pressure regulator
When installing a gas pressure regulator, you need to operate it carefully and properly. The specific installation requirements are as follows:
1. Before installing the gas pressure regulator, the pipeline needs to be pressure tested and purged to ensure that the pipeline is sealed and clean.
2. The liquefied gas pressure regulator should be installed horizontally and vertically on the pipeline. When installing, attention should be paid to making the flow direction of the medium in the pipeline consistent with the direction of the arrow shown on the valve body.
3. Control ball valves should be installed on both sides of the gas pressure regulator, and bypass pipes should be installed for maintenance.
4. Pressure gauges should be installed on the high and low pressure pipelines of the gas pressure regulator to facilitate adjustment, and the pressure changes in front of and behind the valve can be observed during operation.
5. A safety relief valve is installed on the pipeline to ensure the reliability and safety of the gas pressure regulator operation.
6. Indoor gas pipelines should be equipped with gas leakage alarm devices indoors to ensure that when there is a danger of gas leakage, the alarm can be reported in time and the danger can be eliminated.
7. In order to ensure safe use, after installing the gas pressure regulator, be sure to test the tightness. You can use a leak detector or brush soapy water and clean at all pipe interfaces. Check the semen water to see if there is any air leakage. If there is a pressure gauge installed before and after the pressure reducing valve, you can turn off the air source and observe whether the pointer changes.
二、 Precautions for gas pressure regulator installation
1. During installation, the standpipe flange should be parallel to the center distance of the inlet and outlet ball valve flange. It is strictly prohibited to use a crowbar when the difference is too large. Forcibly combined, resulting in excessive deformation of the pipeline, damage to the joint seal and air leakage. The ball valve flange should be screwed until the boss is exposed and the flange gasket can be pressed tightly. Welding with a voltage regulator is strictly prohibited to prevent the high temperature of the welding from burning out the film.
2. Before installing the gas pressure regulator, the pipes connected to the pressure regulator group must be cleaned according to regulations to prevent oxides, sand, and debris in the pipes from clogging the filter.
3. Some models of gas pressure regulators have external signal tubes, such as RTZ-*/0.4A, RTZ-*/0.8AQ series. They must be installed properly during installation and cannot be left uninstalled.
4. When testing the pipeline pressure after installation, the pressure regulator must be blocked with a blind plate and the ball valve must be closed, especially on the downstream outlet side, otherwise the pressure regulator will be easily damaged.
