a: trap: the definition of a trap is used for steam pipe network and equipment, can automatically discharge condensate, air and other gases not condensation, and resistance of steam leakage valve. Steam trap is installed between the steam heating equipment and water back into the manifold. When driving, barrel at the bottom, the valve fully open. After the water into the steam trap flow to the bottom, full body, completely submerged barrel, and then, the condensate to the manifold back by a fully open valve. The steam from the bottom of the barrel into the trap, also occupy the top of the barrel body, create buoyancy. Barrel rises slowly and gradually to the seat direction lever, until completely close the valve. Air and carbon dioxide gas vent holes through the barrel, gathered at the top of the trap. From vent discharge of steam, condensation due to trap the heat. When in the condensate began full barrel barrel to leverage to create a pull. As condensation water level rising, the force of increasing, until can overcome the pressure difference, open the valve. Began to open the Industrial Valves, the differential pressure on the disc will be reduced. Barrel will fell rapidly, make the Industrial Valves fully open. Accumulate at the top of the trap no non-condensable gas discharge first, and then discharge frozen water. When the water flow from barrel sewage flow trap together. Condensate emissions at the same time, steam to enter the trap, and a new cycle begins.

2: control valve, control valve is a kind of water is used since embellish type body, do not need to add oil lubrication, in case of damage of main parts in the valve, please follow the instructions below to remove. ( Note: in general consumption in the valve damage product for diaphragm and ring, other internal components damage little)

1。 The main valve before and after the first side gate valve closed.

2。 The piping on the main valve cover joint screw loosening, pressure release valve.

3。 All the screws removed, including controlling necessary pipeline brass nut.

4。 Take the cover and spring.

5。 To get off axis core, diaphragm, piston, do not damage the diaphragm.

6。 Remove the above things, diaphragm and examine whether the protection ring damage; If no damage do not again points to its internal parts.

7。 If found that the diaphragm or ring was damaged, please loose the nut on the axis core, get to decompose the diaphragm or circle, comes out to replace the new diaphragm or ring.

8。 To examine in detail the main valve internal seat, shaft core whether have damage, if there are other debris inside the main valve to clear it.

9。 Combination is in reverse order will replace the parts after installed the main valve, no jam phenomenon should be the Industrial Valves.

10。 Please refer to installation considerations to use operation. The distinction is obvious, one is the output is the input.
