Classification of Chongqing traps and characteristics of trap valves
The trap is a valve used in steam pipe networks and equipment to automatically discharge condensed water, air and other non-condensable gases, and to block water vapor leakage.
According to the working principle of the steam trap, the Chongqing Da Cai steam trap can be converted into the following types:
Mechanical type: It relies on the change of the height of the condensate in the steam trap, including:
I. Float type: The float is a closed hollow sphere with an open float type: the float is an open-up bucket type. The open-down float type: the float is an open-down bucket type.
Second, thermostatic type: rely on the change of liquid temperature, including 1, bimetal: sensitive original is bimetal. 2. Steam pressure type: The sensitive original is a bellows or ink cartridge, and the inside is filled with volatile liquid. 3. Thermodynamic type: It acts according to the change of the thermodynamic properties of the liquid.
Third, the disc type: due to the different flow rates of liquid and gas under the same pressure, the different dynamic and static pressures generated drive the disk valve.
4. Pulse type: Since the condensed water of different temperatures passes through the two-pole series orifice plate type, the different pressures between the two-pole orifice plate shape act to drive the valve flap to move.
