Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a high-sealing ball valve. Background Art

[0002] A ball valve is a common type of valve used to control the flow of fluid (water or gas). It gets its name from the spherical valve body inside it. The ball valve controls the opening and closing of the fluid by rotating the ball. There is a round hole inside the ball. When the hole is aligned with the pipe, the fluid is allowed to pass; when the hole is turned to a position perpendicular to the pipe, the valve is closed and prevents the fluid from flowing.

[0003] However, most ball valves currently lack a high sealing mechanism when in use, which makes it impossible to ensure that the valve is almost leak-free when in a closed state, which increases the risk of leakage.

[0004] A ball valve disclosed in the announcement number CN208089973U, although a ball valve includes a housing, an end cover arranged at one end of the housing, a valve seat seal accommodated in the housing, a ball valve body movably arranged in the valve seat seal, and a handle connected to the ball valve body and capable of driving the ball valve body to rotate, the housing includes a cylindrical body and a connecting pipe extending outward from one end of the body, the end of the body opposite to the connecting pipe is open, and a joint pipe is screwed and connected thereto, the bottom end of the housing is provided with a discharge hole communicating with the outside, the valve seat seal is provided with an opening corresponding to the pipe hole of the connecting pipe and the pipe hole of the joint pipe, the ball valve body is provided with a through hole passing through both ends of the ball valve body and correspondingly communicating with the opening of the valve seat seal, the top end of the ball valve body is connected to a rotating shaft, the top end of the rotating shaft is connected to the handle, and the rotation of the handle drives the rotating shaft to rotate together with the ball valve body. The ball valve discharges the residual fluid in the housing through the discharge hole, thereby preventing the residual fluid from affecting the service life of the ball valve.

[0005] Although the above patent enables the residual fluid in the shell to be discharged through the discharge hole, thereby preventing the residual fluid from affecting the service life of the ball valve; however, the device lacks a selective water quality detection mechanism, and it is impossible to monitor the water quality in real time when the fluid passes through the valve, which means that if there is a water quality problem (such as excessive chemical substances, microbial contamination, etc.), it may be delayed in discovery, causing the water quality problem to spread or worsen in the system, affecting production or health and safety.

[0006] Therefore, it is necessary to propose a high-sealing ball valve to solve the above problems. Utility Model Content

[0012] As a further solution of the utility model, the auxiliary mechanism includes a U-shaped tube opened on the front side of the outer shell, and the left and right sides of the interior of the U-shaped tube are rotatably connected with a one-way valve. The top of the U-shaped tube is opened on one side of the water quality detector. The U-shaped tube plays a role in transporting the water quality in the outer shell, which facilitates the water quality detector to detect the water quality.

[0019] 1. The highly sealed ball valve is provided with a shell, an elastic mechanism and rubber pads. When the ball valve body is rotated, the two groups of rubber pads will shift to the side away from the central axis of the shell. When the ball valve body is closed, the reverse extrusion force provided by the eight groups of springs drives the two groups of rubber pads to move to the side close to the central axis of the shell, so that the two groups of rubber pads are fixed on the left and right sides of the ball valve body, so that the ball valve body forms a highly sealed state, which is conducive to ensuring that the ball valve body is almost leak-free in the closed state, thereby reducing the risk of leakage.

[0020] 2. The highly sealed ball valve, through the setting of auxiliary mechanisms, water quality detectors, supporting mechanisms and alarms, rotates one of the one-way valves to allow the water in the shell to flow into the U-shaped tube, and then closes the one-way valve and turns on the water quality detector to detect the water quality in the U-shaped tube. When the U-shaped tube detects that the chemical substances in the water exceed the standard or is contaminated by microorganisms, the signal will be transmitted to the alarm, and the alarm will sound an alarm to promptly remind the operator that there is a problem with the water quality, so as to facilitate real-time monitoring of water quality and avoid the spread or aggravation of water quality problems in the system, which may affect production or health and safety.
