Description

Technical Field

[0001] This utility model relates to the field of slide gate valves, and in particular to rectangular transmission slide gate valves. Background Technology

[0002] A slide gate valve (also known as a gate valve or knife gate valve) is a type of valve that controls the flow of media by vertically raising and lowering a gate. Its core function is to cut off, regulate, or isolate fluids through a simple mechanical structure. However, its current drawbacks are that it can only be operated manually, has a low degree of automation, and is unstable during the reciprocating motion of the valve plate. To address these issues, a rectangular transmission slide gate valve was proposed. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] A rectangular transmission slide valve includes a main body, a main body cover vertically disposed above the main body and communicating with the main body, a slide plate vertically inserted into the main body, and cylinders vertically disposed on both sides inside the main body cover and drivenly connected to the slide plate. A distributor is disposed above the outside of the main body cover and connected to the cylinders by a pipe. A solenoid valve is connected to the pipe above the distributor, and the solenoid valve is connected to an external air intake device by a pipe.

[0005] Preferably, the cylinder is provided with a piston that moves up and down reciprocally inside it, and a piston rod that moves synchronously with it is provided at the bottom of the piston. The piston rod is vertically located between the cylinder and the main body, and the bottom end of the piston rod is connected to the bottom ends of both sides of the slide plate.

[0006] Preferably, the upper and lower ends of the outer side of the cylinder are respectively connected to a first air port and a second air port that are connected to the distributor pipeline, and mechanical sensors for sensing the position of the piston are provided at both the upper and lower ends inside the cylinder.

[0007] Preferably, a guide post is provided between the piston and the cylinder, and the guide post is vertically located inside the cylinder, and the guide post passes through the piston and the piston slides along the path of the guide post.

[0008] Preferably, guide wheels that slide with the main body cover are provided on both sides above the skateboard, and guide wheel brackets that roll with the guide wheels are also provided on both sides above the skateboard, and guide rails that slide with the guide wheels are vertically provided on both sides inside the main body cover.

[0009] Preferably, a T-shaped plate and a spring plate are provided between the slide plate and the piston rod, with the T-shaped plate vertically inserted into the main body and the spring plate vertically disposed on the side of the T-shaped plate. The piston rod and the T-shaped plate are synchronously driven and connected, and a guide spring kit that is elastically connected to the slide plate is provided on the side of the spring plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the gas output from the external equipment is transmitted through the solenoid valve, and the gas transmitted from the solenoid valve is split in half through the diverter. The split gas flows to the cylinders on both sides inside the main body cover, thereby causing the cylinders on both sides inside the main body cover to drive the slide plate to move up and down inside the main body, so that the slide plate remains stable during the sliding process.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2In this embodiment of the utility model, the rectangular transmission slide valve includes a main body 15, a main body cover 9 vertically disposed above the main body 15 and communicating with the main body 15, a slide plate 13 vertically inserted into the main body 15, and cylinders 6 vertically disposed on both sides inside the main body cover 9 and driven by the slide plate 13. A distributor 2 is disposed above the outside of the main body cover 9 and connected to the cylinders 6 by a pipe. A solenoid valve 1 is connected to the distributor 2 by a pipe. The solenoid valve 1 is connected to an external air intake device by a pipe. The gas output from the external device is transmitted through the solenoid valve 1, and the gas transmitted by the solenoid valve 1 is split in half by the distributor 2. The split gas flows to the cylinders 6 on both sides inside the main body cover 9, so that the cylinders 6 on both sides inside the main body cover 9 simultaneously drive the slide plate 13 to move up and down inside the main body 15, so that the slide plate 13 remains stable during the sliding process.

[0018] The cylinder 6 is horizontally provided with a piston 11 that moves up and down inside it. The bottom end of the piston 11 is provided with a piston rod 16 that moves synchronously with it. The piston rod 16 is vertically located between the cylinder 6 and the main body 15. The bottom end of the piston rod 16 is connected to the bottom ends of both sides of the slide plate 13. Thus, when the piston 11 moves up and down inside the cylinder 6, it moves up and down through the piston rod 16 and the slide plate 13 inside the main body 15 and the main body cover 9.

[0019] The upper and lower ends of the cylinder 6 on the outside are respectively connected to the first air port 3 and the second air port 5, which are connected to the pipeline of the distributor 2. The upper and lower ends of the cylinder 6 are equipped with mechanical sensors 4 for sensing the position of the piston 11.

[0020] Then, when the mechanical sensor 4 located at the bottom of the cylinder 6 senses that the piston 11 is at the bottom of the cylinder 6, the distributor 2 transmits the gas from the solenoid valve 1 to the second air port 5, and continuously fills the bottom of the cylinder 6 with gas through the second air port 5 until the piston 11 is lifted to the top of the cylinder 6. During the movement of the piston 11, the piston rod 16 moves the slide plate 13 located at the bottom of the main body 15 upward until the slide plate 13 moves to the top of the main body cover 9. At this time, the main body 15 is in the open state.

[0021] When the mechanical sensor 4 located at the top of the cylinder 6 senses that the piston 11 is at the top of the cylinder 6, the distributor 2 transmits the gas from the solenoid valve 1 to the first gas port 3, and continuously fills the top of the cylinder 6 with gas through the first gas port 3 until the piston 11 is pressed to the bottom of the cylinder 6. During the movement of the piston 11, the piston rod 16 moves the slide plate 13 located inside the main body cover 9 downward until the slide plate 13 moves to the bottom of the main body 15. At this time, the main body 15 is in the closed state.

[0022] A guide post 8 is provided between the piston 11 and the cylinder 6. The guide post 8 is vertically located inside the cylinder 6 and passes through the piston 11. The piston 11 slides along the path of the guide post 8, thereby ensuring that the piston 11 remains stable when moving up and down inside the cylinder 6 through the guide post 8.

[0023] The upper sides of the skateboard 13 are provided with guide wheels (not shown in the figure) that slide with the main body cover 9. The upper sides of the skateboard 13 are also provided with guide wheel brackets 10 that roll with the guide wheels. The inner sides of the main body cover 9 are provided with guide rails 7 that slide with the guide wheels. This makes the guide wheels move along the path of the guide rails 7 when the skateboard 13 slides between the main body 15 and the main body cover 9, thus making the skateboard 13 more stable when moving up and down.

[0024] A T-shaped plate 18 and a spring plate 17 are provided between the slide plate 13 and the piston rod 16. The T-shaped plate 18 is vertically inserted into the main body 15, and the spring plate 17 is vertically arranged on the side of the T-shaped plate 18. The piston rod 13 and the T-shaped plate 18 are synchronously driven. The side of the spring plate 17 is provided with a guide spring assembly 12 that is elastically connected to the slide plate 13. Thus, when the piston rod 16 drives the T-shaped plate 18 and the spring plate 17 to move, the guide spring assembly 12 pulls the slide plate 13 to move in the same direction inside the main body 15.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
