Description
Technical Field
The utility model relates to the technical field of stop valves, in particular to a throttle type stop valve.
Background
The shut-off valve is also called a shut-off valve, and belongs to a forced sealing type valve, so that when the valve is closed, pressure must be applied to the valve clack so as to force the sealing surface not to leak. When a medium enters the valve from the lower part of the valve clack, the resistance which needs to be overcome by the operation force is the friction force of the valve rod and the filler and the thrust generated by the pressure of the medium, and the force for closing the valve is larger than the force for opening the valve, so that the diameter of the valve rod is larger, otherwise, the valve rod is in a bending fault. 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 from the upper part of the valve clack to the valve cavity, 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, under the action of the medium, the valve in the form is also tighter. The valve 'three types' in China stipulates that 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, and the flow rate is maximum, which means that the valve has reached the full-open position. The fully open position of the shut-off valve is determined by the stroke of the valve flap.
