Description

Technical Field

[0001] The utility model relates to the field of stop valves, in particular to a welding type electric stop valve. Background Art

[0002] The stop valve is a common type of valve in the manufacturing industry. The main function of the stop valve is to control the flow rate. The electric stop valve is also a type of stop valve. The electric stop valve consists of an electric actuator or a pneumatic actuator and a stop valve. The electric stop valve has a good effect and is popular among users.

[0003] Chinese patent authorization application number: CN202020615360.3 provides an electric stop valve, which improves people's user experience through a rotatable adjustment mechanism. The set rotating shaft and the set socket are fixedly connected to the regulating valve. When using a manual adjustment valve, you only need to rotate the set adjusting column through the set rotating shaft. When the adjusting column is rotated to the set semicircular hollow plate, you only need to press the semicircular hollow plate with your hand, and the semicircular hollow plate will be extended and retracted through the set telescopic hollow column and the set spring. At this time, rotate the adjusting column. When the adjusting column rotates over the semicircular hollow plate, release your hand. At this time, the semicircular hollow plate will return to its original state, thereby fixing the adjusting column and improving the fixing performance of the adjusting column. It is convenient to operate, easy to use, and highly practical.

[0004] The existing electric stop valve has certain disadvantages when in use. First, the existing electric stop valve has a single filtering structure. When replacing the filtering structure, the electric stop valve needs to be disassembled, which reduces the convenience of using and maintaining the filtering structure of the electric stop valve. For this reason, we propose a welded electric stop valve. Utility Model Content

[0040] By installing the positioning rod 203 and pulling a pair of positioning rods 203, the positioning rod 203 can be adjusted in position under the action of the reset spring 204, and the guide ring 207 can limit the movable positioning rod 203, so that the movement and adjustment of the positioning rod 203 is more stable. When the positioning rod 203 moves, the clamping block 205 composed of a movable clamping head is separated from the clamped positioning rod 203, so that the filter plate 201 can be easily disassembled and separated, thereby improving the use and maintenance effect of the electric stop valve.

[0041] Reference Figure 1 As shown, further, the main body mechanism 1 includes an electric stop valve body 101 , a driving assembly 102 is installed on the top of the electric stop valve body 101 , and a protective frame 103 is installed on the outer end of the driving assembly 102 .

When the valve is connected to the external connection component, the sealing ring 301 is adjusted in position under the adjustment position of the movable rod 302, so that the sealing ring 301 can be easily adjusted to different positions, which is convenient for the valve to be connected to the external component and can be easily reset at the connection point for sealing and clamping.

[0048] Specific implementation process: When the valve is connected to an external connection component, the sealing ring 301 is adjusted in position under the adjustment position of the movable rod 302, so that the sealing ring 301 can be conveniently adjusted to different positions, which is convenient for connecting the valve to the external component.

At this time, the clamping block 205 composed of a movable clamping head is separated from the clamped positioning rods 203, so that the filter plate 201 can be easily disassembled and separated, thereby improving the use and maintenance effect of the electric stop valve.
