Description
Technical Field
The invention relates to the field of air tightness detection equipment, in particular to a sealing detection device for a stop valve.
Background
The stop valve is a valve with a circular valve clack as an opening and closing part and can stop the medium from flowing backwards by the action of the self weight and the medium pressure. Belongs to automatic valves, which are also called check valves, one-way valves, reflux valves or isolation valves. The movement modes of the valve clack are divided into a lifting type and a swing type. The lifting stop valve is similar to the stop valve in structure and only lacks a valve rod for driving the valve clack. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). When the inlet pressure is greater than the sum of the valve flap weight and its flow resistance, the valve is opened. Otherwise, the valve is closed when the medium flows backwards. The swing stop valve has a valve clack which is inclined and can rotate around the shaft, and the working principle is similar to that of the lifting stop valve. The shut-off valve is often used as a bottom valve for the pumping device to prevent backflow of water. The stop valve and the stop valve are combined for use, so that the safety isolation function can be realized. The disadvantage is the high resistance and the poor tightness when closed.
The existing check valve needs to be subjected to air tightness detection before leaving the factory to ensure normal operation, the existing detection mode is to fill water into the check valve or put the check valve in water to charge air into the check valve, if air holes exist, air or water leaks out to indicate that the surface is defective, but after the detection mode is adopted, the valve also needs to be subjected to drying treatment, and therefore the check valve is more troublesome.
