Description

Connect reliable angle formula stop valve

Technical Field

The utility model relates to a valve equipment technical field especially relates to a connect reliable angle stop valve.

Background

The angle stop valve opening and closing piece is a plug-shaped valve clack, the sealing surface is a plane or a conical surface, and the valve clack moves linearly along the center line of fluid. The movement form of the valve rod is a lifting rod type (the valve rod is lifted, the hand wheel is not lifted), and a lifting rotating rod type (the hand wheel and the valve rod rotate together to lift, and the nut is arranged on the valve body). The bellows stop valve is only suitable for full opening and full closing, and does not allow adjustment and throttling, and belongs to a forced sealing type valve, so that when the valve is closed, pressure must be applied to the valve clack to force a sealing surface not to leak. When the medium enters the valve from the lower part of the valve clack, the resistance to be overcome by the operating force is the friction force of the valve rod and the packing and the thrust generated by the pressure of the medium, the force for closing the valve is larger than the force for opening the valve, so the diameter of the valve rod is larger, otherwise the failure of the valve rod buckling can occur. In recent years, since self-sealing valves have appeared, the medium flow of the stop valve is changed from above the valve flap to enter the valve cavity, and at this time, the force for closing the valve is small and the force for opening the valve is large under the pressure of the medium, so that the diameter of the valve rod can be correspondingly reduced. At the same time, this type of valve is also relatively tight under the action of the medium. The three-group of valves in China has been specified, and the flow direction of the stop valve is uniformly from top to bottom. When the stop valve is opened, the opening height of the valve clack is twenty-five to thirty-five percent of the nominal diameter, and the maximum flow is reached, which indicates that the valve reaches the full-open position. Therefore, the fully open position of the shut-off valve is determined by the stroke of the valve clack.

The prior art angle stop valve has some disadvantages, such as when the water pressure is high, the resistance for closing the valve becomes large, so the efficiency for closing the valve is low, and it is difficult to close the valve in time, so the prior art needs to be improved.
