Description

Y-shaped packing sealing stop valve

Technical Field

The utility model relates to the technical field of stop valves, in particular to a Y-shaped packing seal 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.

The stop valve provided by the utility model has the advantages that the path of the refrigerant fluid is not greatly turned, the flow is relatively smooth, vortex is not easy to generate, and the pressure loss is small, so that the energy consumption is reduced. The inventors found that the following problems exist in the prior art in the process of implementing the present utility model: 1. in the process of working, the traditional Y-shaped packing sealing stop valve needs to be installed at first, and in the process of installation, workers need to use other auxiliary parts, the installation process is complicated, and after long-time use, the joint of the stop valve can be corroded, so that the phenomenon of poor sealing performance is caused;
