The installation of pressure gauges for Fangkuai boilers depends first on the pressure point and the space position of the pressure gauge (or pressure transmitter), and then on what pipeline accessories there are and how to lay them. (1) in order to measure the static pressure correctly, The extraction port must be perpendicular to the medium flow. No chamfering, flanges, and burrs. When measuring the liquid pressure, the pressure-taking port shall be drawn from the lower part of the pipe section, so as to prevent the gas in the liquid from entering the pressure-guiding line; When measuring the gas pressure, the pressure-taking port should be drawn from the top of the pipe section to prevent dust in the gas and water droplets from entering the pressure-guiding pipeline. (2) the inner diameter of the pressure-taking pipe is usually φ 7 / 1. 3mm (for water, steam), its length should not be too long (< 60m). If the diameter and length of the pressure-taking pipe are too small, the dynamic transmission of pressure measurement will be affected and the dynamic error will be increased. The inner diameter is too large, not easy to maintain and install. The pressure-taking line shall not be laid horizontally in order to prevent the accumulation of bubbles (when measuring the liquid) and the water column (when measuring the gas). (3) the pressure-taking line must be fitted with a needle-shaped valve (to cut off the pressure in the event of failure of the pressure-taking line in operation), Secondary needle valves (instrumentation, stop, replacement), condensing coil and elbows (isolation elastomers from high-temperature heating in the medium and easy to install sealing patches); and Sewerage valves and sewerage lines, etc. For special pressure measurement, the pressure taking line must also be equipped with vent valves, isolation rooms, etc. (4) the installation site of the pressure gauge (pressure transmitter) shall meet the environmental conditions (temperature, humidity, vibration, etc.) used by the instrument, At the same time, it should be easy to observe, repair and ensure safety. The pressure-taking pipeline of high-temperature medium must be coated with a thermal insulation layer to avoid scald when punching the tube.

Weak production technology, poor manufacturing quality. According to statistics, some manufacturer's technical force is very weak, and some manufacturers is not even a professional and technical personnel boilers, pressure hot water boiler theory itself is little understood. Some did not design data, verification data, some manufacturers only copied from drawings of pressure hot water boiler, which replaced the opening serve. Thus leading to poor manufacturing quality boilers, it has brought accidents.

How a Steam Heat System Works | DoItYourself.com

Steam Heat System Basics. The steam heating system is made up of a water boiler, a burner, the pipes, and radiators and/or convectors. The way a steam heat system works is fairly straight-forward. The boiler heats the water, turning it into steam. The steam then travels through the pipes to the radiators and/or convectors in each room.
