Detailed Description

The present invention will be further described in detail with reference to specific embodiments, which are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are provided, but the present invention is not limited to the following embodiments.

Referring to fig. 1 to 5, a fast high-tightness valve specifically includes: the valve comprises a valve body 1, a valve core 2, an actuator 3 and a switch assembly 5, wherein the actuator 3 is fixedly connected with a valve core shell through an actuator base 4.

And the upper end and the lower end of the valve body 1 are provided with limiting baffles 11 for limiting.

Referring to fig. 2 and 3, the valve core 2 further includes a main shaft 21, a bearing 22 with a seat fixedly connected to the main shaft 21 after being sleeved, and a bearing base 23 used in cooperation with the bearing 22; the bearing base 23 is internally provided with a sealing seat 24 and a sealing cover plate 25 matched with the sealing seat; the sealing seat 24 and the sealing cover plate 25 are fixedly connected to the main shaft 21 after being sleeved in the same way; the arrangement of the sealing seat and the sealing cover plate greatly improves the valve tightness. Referring to fig. 4, in addition to the use of bolts 26 for fastening the cartridge 2 housing during assembly, a relatively thick pressure plate 27 and three thin, differently sized sealing pressure plates 28 are provided on the nut side of the bolts, wherein the largest sealing pressure plate is placed adjacent to the cartridge housing and the smallest sealing pressure plate is placed adjacent to the pressure plate 27, which again improves the valve tightness.

The switch assembly 5 further comprises a push rod 51 and a push rod knob 52; one end of the push rod 51 is fixedly connected with the actuator 3, and the other end is fixedly connected with a handle of the push rod knob 52; one end of the rotating shaft of the push rod knob 52 is fixedly connected to the main shaft 21, and can drive the main shaft 21 to rotate. The push rod, the push rod knob, the main shaft and the valve core form a transmission mechanism together, and the valve core rotates at 0-90 degrees to realize the opening and closing functions of the valve.

The actuator 3 described in this embodiment can use an angular travel actuator, and is used in cooperation with an angular travel valve, so that the valve can control the on-off of the pipeline fluid within 90 degrees by screwing. The voltage is between AC24-220V, the analog quantity signal can be purchased with higher control precision, and if the precision requirement is not high, a three-bit signal is adopted.
