Description

Technical Field

[0001] The invention relates to the technical field of ball valves, in particular to a manual-pneumatic-electric integrated fluorine-lined ball valve. Background Art

[0002] Manual pneumatic electric fluorine-lined ball valve can be divided into two structural types: two-piece type and three-piece type. It has small fluid resistance, fast opening and closing speed and simple structure.

[0003] However, the existing manual pneumatic electric integrated fluorine-lined ball valve is equipped with a rubber ring inside, but there are many types of fluids in the ball valve. High temperature or corrosion will cause the rubber ring to deform, thereby reducing the sealing performance of the ball valve, causing the ball valve to be scrapped and unusable, reducing the service life of the ball valve; therefore, there is a lack of a manual pneumatic electric fluorine-lined ball valve that is easy to disassemble and repair and has good sealing performance. Summary of the invention

[0004] The purpose of the present invention is to propose a manual-pneumatic-electric integrated fluorine-lined ball valve in order to solve the above-mentioned problem.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A hand-operated electric integrated fluorine-lined ball valve comprises a ball valve housing and a ball, wherein barrel bodies are symmetrically mounted at both ends of the ball, a connecting hole connecting the two barrel bodies is arranged in the ball, the top of the ball is connected to the inner wall of the ball valve housing via a second sealing component, and the outer wall of the barrel body is connected to the ball valve housing via a third sealing component; a ball support mechanism, wherein the ball support mechanism comprises a support shell, wherein the ball support mechanism is mounted on the bottom of the ball valve housing, and the bottom of the ball is connected to the inner wall of the support shell via a first sealing component; a rotating handle, wherein the rotating handle passes through the ball valve housing and is mounted on the ball.

[0007] As a further description of the above technical solution:

[0008] The ball valve housing and the support shell match the outer shapes of the ball and the barrel, and the outer diameter of the barrel is larger than the inner diameter of the connecting holes opened at both ends of the ball valve housing.

[0009] As a further description of the above technical solution:

[0010] A rubber strip is rigidly connected to the center of the inner side of the support shell, and a plug hole for plugging and fitting the rubber strip is arranged at the bottom of the sphere.

[0011] As a further description of the above technical solution:

[0012] The inner end surface of the support shell is provided with a rubber ring in an annular structure, and the outer wall of the ball valve housing is provided with a clamping groove for clamping the rubber ring.

[0013] As a further description of the above technical solution:

[0014] A side plate is fixedly connected to the outer wall of the ball valve housing, a mounting plate is fixedly connected to the periphery of the support shell, and the mounting plate is fixedly connected to the side plate by bolts.

[0015] As a further description of the above technical solution:

[0016] A handle cap is arranged on the top of the ball valve housing, and the handle cap is sleeved outside the rotating handle. The handle cap is fixedly connected to the ball valve housing by bolts.

[0017] As a further description of the above technical solution:

[0018] A sealing ring is sleeved on the outer side of the rotating handle, and the sealing ring is located in the handle cap.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] 1. In the present invention, the support shell installed at the bottom of the ball valve housing is sealed and connected to the ball through the first sealing component. A detachable handle cap is provided on the top of the ball valve, so that the ball support mechanism and the handle cap can be disassembled and assembled with the ball valve housing, thereby making it easy to disassemble, inspect and repair the inside of the ball valve, thereby improving the usability and service life of the ball valve.

[0021] 2. In the present invention, barrel bodies are provided on both sides of the sphere, so that the ball valve housing, the sphere, the barrel body and the ball support mechanism are connected through sealing components respectively, thus timely avoiding the deformation of the rubber material and the sealing problem inside the ball valve. The meshing cooperation of the rings ensures the good sealing of the ball valve body. BRIEF DESCRIPTION OF THE DRAWINGS
