Technical Field

[0001] The utility model relates to the technical field of spherical valve body forgings, in particular to a high-strength spherical valve body forging. Background Art

[0002] A ball valve is a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can be used for regulating and controlling fluids.

[0003] For example, Chinese patent CN 219712476 U discloses a high-strength pressure-resistant valve body, which relates to the field of valve technology. It is a high-strength pressure-resistant valve body, including a valve body and a pipeline. The left and right ends of the valve body are both provided with a first flange, and a valve core assembly for controlling the switch is provided inside the first flange. One end of the pipeline is fixedly installed due to the second flange.

[0004] The above-mentioned high-strength compressive-resistant valve body still has certain shortcomings. It connects the second flange and the first flange by means of a nut thread sleeve on the surface of the bolt. Although it can improve the compressive strength of the valve body after closing, the connection of multiple nuts and bolts on the left and right sides is not only cumbersome during installation and disassembly, but also controls the flow of liquid in the valve body and the pipeline by adjusting the knob, so that the liquid directly impacts the inner wall of the inner cavity of the valve body. After long-term use, the inner wall of the inner cavity of the valve body may be damaged, thereby reducing the service life of the valve body. Utility Model Content

[0008] Furthermore, the bottom end of the valve stem penetrates the upper surface of the valve seat and extends to the inside of the valve body and is fixed with a valve plate, and sealing rings are installed between the two first pipes and the second pipes.

[0009] Furthermore, the adjustment mechanism also includes a connecting rod fixed to the right end of the worm, and a handle is fixed to the right end of the connecting rod.

[0010] Furthermore, the two rotating rods are rotatably connected to the inner top wall of the installation box through bearings, and the two rotating rods are rotatably connected to the inside of the two connecting blocks through bearings respectively.

[0011] Furthermore, the connecting mechanism includes two fixing seats fixed on the outside of the first pipe on the left, and the outer sides of the two fixing seats are rotatably connected with pull ring handles. Two limiting seats are fixed on the outer side of the second pipe on the left, and the outer sides of the two pull ring handles are rotatably connected with pull buckles.

[0016] 2.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 A high-strength spherical valve body forging in this embodiment includes a valve body main body 1, the left and right sides of the valve body main body 1 are fixedly connected with a first pipeline 6, the opposite sides of the two first pipelines 6 are movably fitted with a second pipeline 7, a valve seat 3 is fixed at the top of the valve body main body 1, and the upper surface of the valve seat 3 is rotatably connected to a valve stem 5, an adjusting mechanism 2 is provided on the left side of the valve body main body 1, and a connecting mechanism 4 is provided on the left side of the valve body main body 1.

[0023] The bottom end of the valve stem 5 penetrates the upper surface of the valve seat 3 and extends to the inside of the valve body 1 and is fixed with a valve plate. Sealing rings are installed between the two first pipes 6 and the second pipe 7.

[0024] See also Figure 2 In order to adjust the flow rate in the first pipe 6, the regulating mechanism 2 in this embodiment includes an installation box 201 fixed on the upper surface of the left first pipe 6, and a worm 202 is rotatably connected between the left and right side walls of the inner cavity of the installation box 201 through a bearing, and a worm gear 203 is meshed on the front and rear sides of the worm 202. A rotating rod 204 is fixed inside the two worm gears 203, and a connecting rod 205 is fixed between the top wall and the bottom wall of the inner cavity of the left first pipe 6. Two connecting blocks 206 are fixed on the outside of the connecting rod 205. The bottom ends of the two rotating rods 204 penetrate the upper surface of the first pipe 6 and extend into the inside thereof, and fan-shaped regulating plates 207 are fixed on the outside.

[0025] In this example, there are two adjusting mechanisms 2 and two connecting mechanisms 4, which are symmetrically distributed with the central axis of the valve body 1 as the symmetry line. The adjusting mechanism 2 also includes a connecting rod fixed to the right end of the worm 202, and a handle is fixed to the right end of the connecting rod. When the handle is turned, the worm 202 starts to rotate and drives the two worm wheels 203 to rotate. The two rotating rods 204 are rotatably connected to the inner top wall of the installation box 201 through bearings. When the two worm wheels 203 start to rotate in opposite directions, the two rotating rods 204 respectively drive the two fan-shaped adjusting plates 207 to start flipping, thereby achieving the purpose of adjusting the flow in the first pipeline 6. The two rotating rods 204 are respectively rotatably connected to the inside of the two connecting blocks 206 through bearings, which can avoid high-intensity water pressure from directly impacting the inner wall of the valve body 1 and reducing the service life of the valve body 1.

[0026] It should be noted that when it is necessary to install or remove the two first pipes 6 and the second pipe 7, the left and right pull ring handles 403 are pushed toward the direction of their limit seats 402 respectively, so that the left and right pull buckles 404 are driven to separate from the left and right limit seats 402. At this time, the two first pipes 6 and the second pipes 7 can be easily installed or removed, and the installation is more secure.

[0027] See also Figure 3 In order to facilitate the installation or disassembly of the two first pipes 6 and the second pipe 7, the connecting mechanism 4 in this embodiment includes two fixing seats 401 fixed on the outer side of the left first pipe 6, and the outer sides of the two fixing seats 401 are rotatably connected with pull ring handles 403, and the outer side of the left second pipe 7 is fixed with two limit seats 402, and the outer sides of the two pull ring handles 403 are rotatably connected with pull buckles 404.

[0028] In this example, the two pull buckles 404 are respectively sleeved on the outside of the two limit seats 402. When the two first pipes 6 and the second pipes 7 need to be installed or removed, the left and right pull ring handles 403 are pushed toward the direction of their limit seats 402 respectively, so that the left and right pull buckles 404 are driven to separate from the left and right limit seats 402. At this time, the two first pipes 6 and the second pipes 7 can be easily installed or removed, and the installation is more firm.

[0029] It should be noted that by pushing the left and right pull ring handles 403 toward their limit seats 402 respectively, the left and right pull buckles 404 are driven to separate from the left and right limit seats 402, which makes it easy to install or remove the two first pipes 6 and the second pipe 7.

[0030] It is understandable that in the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood through specific circumstances. At the same time, the parts not described in detail in the present invention are all well-known technologies of those skilled in the art.

[0031] The working principle of the above embodiment is:

[0032] (1) When the high-strength spherical valve body forging is needed, in order to prevent high-strength water pressure from directly impacting the valve body 1, the handle can be turned to cause the worm 202 to start rotating and drive the two worm wheels 203 to start rotating in opposite directions, so that the two rotating rods 204 respectively drive the two fan-shaped adjustment plates 207 to start turning, thereby achieving the purpose of adjusting the flow in the first pipeline 6, preventing high-strength water pressure from directly impacting the inner wall of the valve body 1 and reducing the service life of the valve body 1.

[0033] (2) When it is necessary to install or remove the two first pipes 6 and the second pipe 7, the pull ring handles 403 on the left and right sides are pushed toward the direction of their limit seats 402 respectively, so that the pull buckles 404 on the left and right sides are driven to separate from the limit seats 402 on the left and right sides. At this time, the two first pipes 6 and the second pipe 7 can be easily installed or removed, and the installation is more secure.
