Drain valve office principle: 1. The steam trap installed in steam heating facilities and solidification between water back into the manifold. Barrel rises slowly and gradually to the seat direction lever, until absolutely close the valve. Q: on hydrophobic valve type production and office principle a: drain valves are used in steam pipe network and facilities, can be taken out semi-automatic coagulation, water, air and other gases, and resistance of steam leak valve. Trap type category: according to the principle of steam drain valve office, steam valve can be turned into the following types: with the doctrine of hydrophobic 1: mechanical type: to rely on coagulation water in the steam drain valve fluid who highly variable Marine valves and ( 1) Ball float, float for closed hollow spherical stereo ( 2) Exposure aspirant float type: float for mouth of bucket ( 3) Exposure to downward float type: float down for mouth bucket 2: hot static type: depends on degree of temperature change and body movement of the fluid ( 1) Bimetallic strip: acute original of bimetallic strip ( 2) Steam pressure type: original keen for speckle tube or cartridge, inside filling the volatile liquid 3: thermodynamic model: depends on the change of thermal dynamic properties of the liquid and action. Accumulation in trap at the top of the non-condensable gas discharge first, and then frozen water. When driving, barrel at the bottom, the valve the whole paper. From exhaust eye discharge of steam, due to the cooling and solidification of trap. 3. When in the frozen water of full barrel barrel to lever up a tension. Frozen water discharge at the same time, the steam from the new start into the trap, a new cycle has started again. 。 After coagulation water into the steam trap flow to the bottom, full body, all submerged barrel, and then frozen water Industrial Valves to the manifold back through the whole paper. 2. The steam from the bottom of the barrel into the trap, occupy the top of the barrel body, on the initiation pressure. ( 1) Disc type: because under the same pressure, liquid and gas flow rate, the initiation of different dynamic, static pressure, goad disc valve action ( 2) Electronic pulse type: because of the different temperature of coagulation water through polar orifice plate series, sitting between the poles throttling orifice plate shape is not the same pressure, goad disc movement. With coagulation water mark a rising, initiation of strength increasing, until can overcome differential pressure, open the valve. Air and carbon dioxide gas passes through the barrel exhaust gas eye eye, gathered at the top of the trap. 4. The valve to open, the utility on the disc pressure differential will decrease. Barrel will be a sudden loss, make the valve the whole paper. When the water flow from barrel help and outflow trap dirt. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
