There are many factors that determine the price of steam boilers, mainly operating efficiency, pollutant emissions, floor space, internal structure, service life, and so on. The higher the configuration of the boiler, the more expensive it will be, but the greater the benefits it will bring, it can be said that it has a very high cost performance. At present, the price of a 4-ton gas-fired steam boiler in the market is between US$30,000 and US$40,000.
Zhengzhou Fangkuai Boiler Factory would like to remind everyone here that the boiler must be equipped with appropriate safety valve facilities to ensure safety during operation.
The pulse safety valve is composed of the main safety valve, the pulse valve and the connecting pipeline.
The main safety valve is controlled by a small pulse valve. Under normal conditions, the main valve is tightly closed by high-pressure steam. When the vapor pressure exceeds the specified value. The small pulse valve is opened first, and the steam is introduced to the main valve piston through the steam guide tube. The pressure of the steam on the piston can overcome the force of the spring compression, so the main valve is opened to discharge the steam and the pressure; when the pressure drops to a certain value, The small pulse valve is closed. The steam flow on the piston is cut off, so the main relief valve is closed again. The residual steam on the piston can play a buffering role, so that the main valve is slowly closed to avoid damage to the valve clack and valve seat due to impact.
