Description

Card bamboo shoot formula valve clack stop valve with outside protect function

Technical Field

The utility model relates to a technical field of stop valve especially relates to a card bamboo shoot formula valve clack stop valve with outside protect function.

Background

The shut-off valve is also called a shut-off valve, and belongs to a forced sealing type valve, so when the valve is closed, pressure must be applied to the valve clack to force the 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 between 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. The connection mode is divided into three types: flange connection, screw thread connection and welding connection. After the self-sealing valve appears, the medium flow direction of the stop valve is changed to enter the valve cavity from the upper part of the valve clack, at this time, under the action of medium pressure, the force for closing the valve is small, the force for opening the valve is large, and 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 valve of China has been specified in the 'three-transformation and three-transformation' way, 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 25% -30% of the nominal diameter, the flow reaches the maximum, and 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 existing stop valve is exposed outside in the use process, and meanwhile, a protection structure is not arranged outside the stop valve, so that the stop valve is extremely easy to be damaged by external force, and the service life of the stop valve is shortened.
