Problems solved by technology

This kind of seal has good sealing performance, but it is not resistant to high temperature, easy to wear, and has poor mechanical properties.
[0004] For traditional smart ball valves, when the pressure of the water flow in the ball valve is too large, the ball is forced to squeeze the soft seal, which may cause deformation and damage of the soft seal. At the same time, as the ball moves, a gap will appear on the opposite side of the soft seal, resulting in water leakage. question

Abstract

The invention discloses an intelligent ball valve based on fluid pressure, and belongs to the field of intelligent ball valves.The intelligent ball valve based on the fluid pressure comprises a valve body, a movable groove is formed in the valve body, a ball body is installed in the movable groove, the top end of the valve body is connected with a valve rod assembly in a penetrating mode, and the bottom end of the valve rod assembly is connected with the top end of the ball body in a clamped mode; a sliding groove is formed in the inner wall, close to the left end, of the valve body, a sliding block is slidably connected into the sliding groove in a limited mode, a sliding ring is fixedly connected to one side of the sliding block, the sliding ring is slidably connected with the inner wall of the valve body in a limited mode, and a limiting shaft is fixedly connected to the side, opposite to the ball body, of the sliding block. A second sealing ring is slidably connected to the side, opposite to the sliding ring, of the ball in a limiting mode, two sealing hoses are fixedly connected to the side, opposite to the ball, of the second sealing ring, the two sealing hoses are arranged in a sleeved mode, and the effect that the other side of the soft seal of the ball is continuously sealed under the high water pressure can be achieved.

Description

technical field [0001] The invention relates to the field of intelligent ball valves, and more particularly, to an intelligent ball valve based on fluid pressure. Background technique [0002] The working principle of the ball valve The rotation angle of the ball is between 0 and 90°. When it rotates to 90°, the ball valve is fully open. The ball valve structure is mainly divided into two types: fixed type and floating type. The common small-diameter ball valves are all floating structures. Under the action of pressure and fluid, the valve seat where the ball flows to the medium is sealed and compressed to achieve the sealing effect. The greater the pressure, the better the sealing. it is good. The structure of the fixed ball valve is simply that there are shaft pins at the top and bottom of the center of the ball valve. In large-diameter occasions, a fixed ball valve must be used to avoid crushing the seal according to the weight of the ball. The eccentric ball valve and t...
