Description

Technical Field

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

[0002] With the development of our society, ball valves are widely used in oil refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel and other industries, and they play an important role in the national economy.

[0003] The ball valve usually includes a valve body, which is provided with a water inlet hole and a water outlet hole. A valve core is rotated in the valve body, and a water through hole is penetrated on the valve core. A valve stem is arranged on the outer wall of the valve core, and the valve stem penetrates the valve body to the outside. The valve core is rotated to control whether the water through hole is connected with the water inlet hole and the water outlet hole.

[0004] The existing ball valve handle can only be rotated in one direction. When the space is small or there are obstacles, the handle will be blocked, which will affect the use of the ball valve and make it inconvenient to use.

[0005] Therefore, a straight-through ball valve is urgently needed to solve the technical problems described above. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide a straight-through ball valve.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is a straight-through ball valve: comprising a valve body, a ball, and a valve stem, wherein the ball is arranged in the valve body, a sealing ring is arranged at the position where the upper and lower ends of the ball contact the valve body, a valve stem is arranged at the upper end of the ball, a high platform is arranged at the upper end of the valve body, and the valve stem extends from the high platform; the characteristics are: the front end of the high platform is symmetrically provided with a limit plate, the middle part of the rear end of the high platform is provided with a limit part, the upper end of the valve stem is provided with a handle in a detachable manner, and the rear end of the handle is provided with a baffle;

[0008] A card slot is symmetrically arranged above the handle at the upper end of the valve stem, and a limit card is arranged in the card slot, and the limit card limits the handle;

[0009] The baffle plate cooperates with the limiting plate and the limiting part.

[0010] Compared with the prior art, the utility model has the following advantages: a limit plate is symmetrically arranged at the front end of the high platform, a limit part is arranged in the middle of the rear end of the high platform, a handle is rotatably arranged at the upper end of the valve stem, and a baffle is arranged at the rear end of the handle, so that the installation direction of the handle can be adjusted. Since the limit plates are symmetrically arranged at the front end of the high platform, this will not affect the normal use of the ball valve. In this way, the use of the ball valve will not be restricted in places with small spaces or obstacles, and it is more convenient and flexible to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Combined with Figure 1-7A straight-through ball valve comprises a valve body 100, a ball 200 and a valve stem 300. The ball 200 is arranged in the valve body 100. A sealing ring is arranged at the position where the upper and lower ends of the ball 200 contact the valve body 100. The upper end of the ball 200 is provided with a valve stem 300. The upper end of the valve body 100 is provided with a high platform 101, and the valve stem 300 extends from the high platform 101; it is characterized in that: the front end of the high platform 101 is symmetrically provided with a limit plate 102, the middle part of the rear end of the high platform 101 is provided with a limit part 103, the upper end of the valve stem 300 is provided with a handle 104 in a detachable manner, and the rear end of the handle 104 is provided with a baffle 105;

[0022] A slot 301 is symmetrically arranged above the handle 104 at the upper end of the valve stem 300. A limit card 302 is arranged in the slot 301. The limit card 302 limits the handle 104. The limit card 302 can be made of metal and can produce elastic deformation when subjected to force.

[0023] The baffle plate 105 cooperates with the limiting plate 102 and the limiting portion 103 to adjust the installation direction of the handle without affecting the use of the ball valve.

[0024] The baffle 105 is located on one side of the center line of the rear end of the handle 104 .
