Description

Multifunctional stop valve

Technical Field

The utility model relates to the technical field of valves, especially, relate to a multifunctional stop valve.

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.

Patent number CN209511123U discloses a stop valve, be equipped with in the valve body with valve clack, valve gap matched with valve rod, the middle part of valve rod is equipped with prevents changeing the board group, and the hand wheel is installed on the upper portion of valve rod, links to each other through valve-stem nut between hand wheel and the valve rod, and the top of valve rod is equipped with the instruction piece, is equipped with on the hand wheel and instructs piece complex stroke indicator cover. In implementation, under the effect of preventing changeing the board group, the circumference of valve rod is spacing, can only do axial reciprocating motion, and the valve clack follows the valve rod motion, and then opens or close the disk seat, because the valve clack only axial atress, does not have circumference friction, has protected sealed face, has prolonged life. Meanwhile, the indicating cover observation groove can visually reflect the movement position of the valve clack, avoid damage to valve parts caused by excessive torque and improve safety.

The above-mentioned shut-off valve has several disadvantages when in use: 1. above-mentioned stop valve can not guarantee the inside gas tightness of valve body when using for the condition emergence of revealing appears easily in the valve.

2. Above-mentioned stop valve can not detect the inside gas tightness of valve body when using for leak in the valve appears easily, and the condition that influences the use takes place.
