Description

Technical Field

[0001] The utility model relates to a ball valve, in particular to a curved pipe ball valve. Background Art

[0002] The ball valve is a valve that is driven by the valve stem and rotates around the axis of the ball valve as an opening and closing part. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with hard alloy surfacing, which is particularly suitable for media containing fibers, tiny solid particles, etc.

[0003] There are many types of existing ball valves, including elbow ball valves. When using a traditional elbow ball valve, it is used to connect two pipes. However, due to its limited length, it is difficult to connect two pipes that are far away. Secondly, the impact of the water flow on the bend inside the valve body is very large. If this continues for a long time, it will greatly accelerate aging and shorten its service life. Therefore, a elbow ball valve is proposed here to solve the above problems. Utility Model Content

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1-4As shown, a bent pipe ball valve includes a valve body 1, which is arranged in an L shape, and the bending part of the valve body 1 is arranged in an arc surface. Mounting heads 8 are installed at both ends of the valve body 1, and telescopic hoses 7 are installed on the side of the two mounting heads 8 close to the inner cavity of the valve body 1. The end of the telescopic hose 7 away from the mounting head 8 extends to the inner cavity of the valve body 1, and a ball 2 is arranged in the inner cavity of the valve body 1. A circular groove 3 is opened on the ball 2, and a valve stem 4 is fixedly connected to the top of the ball 2. The top end of the valve stem 4 passes through the top of the valve body 1 and is fixedly connected to a handle 5, and the valve stem 4 is movably connected to the top of the valve body 1, and a buffer mechanism is provided on the right side of the ball 2.

[0022] The buffer mechanism includes a plurality of mounting blocks 12, which are evenly distributed in a ring shape, and are all fixedly connected to the inner wall of the valve body 1. A buffer spring 11 is fixedly connected to the left side of the mounting block 12, and a buffer plate 10 is fixedly connected to the left end of the buffer spring 11. One side of the buffer plate 10 is fixedly connected to the inner wall of the valve body 1.

[0023] In this embodiment, this arrangement can achieve a buffering effect on the impact force of the water flow, thereby preventing the strong impact force of the water flow from directly acting on the inner wall of the valve body 1, accelerating its aging and shortening its service life.

[0024] Among them, one end of the telescopic hose 7 away from the mounting head 8 is fixedly connected to the mounting ring 6, and the outer wall of the mounting ring 6 is fixedly connected to the inner wall of the valve body 1;

[0025] In this embodiment, the fixing operation between the telescopic hose 7 and the inner wall of the valve body 1 is achieved through this arrangement.

[0026] The outer side of the mounting head 8 is sleeved with a mounting sleeve 9, and the mounting sleeve 9 is sleeved on the outer wall of the valve body 1;

[0027] In this embodiment, the fixing operation between the mounting head 8 and the outer wall of the valve body 1 is achieved through this arrangement.

[0028] Working principle: When in use, the two mounting heads 8 can be connected to the corresponding pipes. If the distance between the two pipes is far, the two mounting sleeves 9 can be removed from the outside of the valve body 1, and then the telescopic hose 7 can be pulled out of the valve body 1 to achieve the separation between the two mounting heads 8 and the valve body 1. At this time, the two mounting heads 8 can be connected to the corresponding pipes. When water flows inside the pipe, it will pass through the circular groove 3 on the sphere 2 and flow to other positions along the top mounting head 8. When it needs to be cut off, just turn the handle 5 so that the handle 5 drives the valve stem 4 to rotate, and the valve stem 4 drives the sphere 2 to rotate. The sphere 2 rotates the circular groove 3 to the front and back settings to achieve the cutoff inside the valve body 1. After the water flows through the circular groove 3, a plurality of buffer plates 10, a plurality of buffer springs 11 and a plurality of mounting blocks 12 are used to form a buffer assembly to achieve the buffering of the water flow impact force, so as to avoid the large water flow impact force directly acting on the bend of the valve body 1, causing it to age and affect its service life.

[0029] Finally, it should be noted that in the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings.
