Structure and operation method of combined valve

the combined valve is composed of a valve core and a valve seat. The upper part of the valve seat is connected with 4-5 water inlet pipes. The solid oil cylinder will gradually fall down. Taking the machine frame will cause serious consequences. The lower part of the overall steel plate welded frame structure is connected with a water outlet pipe. The valve core is a cylinder, and mutually perpendicular holes are drilled at the bottom and middle of the cylinder. The valve core and the valve seat are connected by dynamic fit

when the boiler blowdown, turn the movable core through the handwheel. When the hole in the middle of the valve core is opposite to a water inlet pipe orifice on the valve seat, the water in the circulating circuit connected to the water inlet pipe will be discharged from the outlet pipe under the valve seat after passing through the valve seat and valve core, and the blowdown will be stopped Just turn the hand wheel to stagger the hole in the middle of the valve core with the hole on the estrangement seat. When the boiler is shut down to drain water, withdraw the pin on the combined valve and lift the valve core. The five circulating circuits connected by the five points can pass through the lower part of the valve seat at the same time. Each 2014 f ⑴ 50 car includes sufficient recycled cotton outlet pipes to drain water, which shortens the boiler drain time
