Description

Technical field:

[0001] The utility model relates to the technical field of valves, in particular to a novel mechanism plug-in valve. Background technology:

[0002] A gate valve, also known as a slip valve or sliding valve, is a valve used to control fluid flow. A gate valve typically consists of a valve body, a valve disc, seals, and an actuator. The gate slides within the valve body, opening and closing the valve. The disc can be round or square to accommodate different piping systems. Gate valves are primarily available in manual, pneumatic, hydraulic, and electric configurations. Hydraulic gate valves are currently the most common type. During operation, hydraulic oil is pumped to the control valve station of the hydraulic cylinder via a hydraulic pump. Adjustment of the solenoid valve controls the cylinder's expansion and contraction, thereby controlling the opening and closing of the gate valve. However, hydraulic gate valves are prone to solenoid valve sticking and hydraulic cylinder seal damage, which can cause the gate valve to malfunction. Furthermore, the use of a cover plate to protect the hydraulic cylinder makes it difficult to accurately determine the gate valve's position in the event of a problem, making maintenance difficult. Utility model content:

[0003] In order to solve the above technical problems, the purpose of the present utility model is to provide a new type of mechanism gate valve.

[0004] The cam is fixedly provided with a toothed connection portion for the toothed connection, and the toothed connection portion is fixedly provided with a toothed connection portion for the toothed connection.

[0007] Furthermore, the crank is disc-shaped.

[0008] Furthermore, the plug valve housing and the motor holder are fixedly connected via a rib plate.

[0009] The beneficial effects of the utility model are: it is driven by a motor, has a simple structure, and is reliable to use; the transparent upper cover of the plug valve box body can be used to observe the situation inside the plug valve box body, which is convenient for inspection and maintenance; the lower cover plate can collect materials brought out when the plug valve is opened, and can be cleaned regularly; the motor and the crank are placed outside the box body, and the position of the plug valve in the box body can be judged according to the rotation position of the crank, and damage caused by the entry of materials can also be avoided.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Combine Figure 1-3As shown, the utility model is a new type of mechanism gate valve, including a gate valve box 3 fixedly connected to a feed pipe flange 1 and a discharge pipe flange 2, an upper cover plate 11 and a lower cover plate 12 are provided on the gate valve box 4 outside the feed pipe flange 1, and the upper cover plate 11 and the lower cover plate 12 are respectively screwed to the gate valve box 3, the upper cover plate 11 is transparent, which is convenient for inspection and maintenance, and the lower cover plate 12 can collect the material brought out when the gate is opened, and clean it regularly. The gate valve box 3 is slidably connected to a gate valve box 3 that is parallel to the gate valve box 3, and one side of the gate valve 4 is fixed. A connecting rod 5 is fixedly connected to the gate valve 4, and its axis intersects with the axis of the feeding pipe flange 1. The connecting rod 5 passes through the gate valve housing 3 and is fixedly connected to the chute 6. A motor holder 7 is fixedly connected to the outside of the gate valve housing 3 on one side of the connecting rod 5. The gate valve housing 3 and the motor holder 7 are also connected by a rib plate 13 to improve the stability of the gate valve. A motor 8 is screwed to the bottom surface of the motor holder 7. A crank 9 is fixed to the output shaft of the motor 8. The crank 9 is disc-shaped and can prevent damage to the motor 8 caused by falling materials. A cylinder 10 is fixed to the edge of the top surface of the crank 9, and the cylinder 10 is slidably connected to the chute 6.

[0017] Working principle:

[0018] During operation, the motor 8 rotates to drive the crank 9 to rotate, and the cylinder 10 on the crank 9 makes a circular motion. The cylinder 10 gives the chute 6 a tangential force along the tangential direction of the circle. The force exerted by the cylinder 10 on the chute 6 can be divided into two directions: along the center line of the chute 6 and perpendicular to the center line of the chute 6. The force along the center line of the chute 6 is transmitted to the connecting rod 5 and acts on the gate valve box 3. The force along the center line of the vertical chute 6 drives the chute 6 to make a linear motion, thereby driving the connecting rod 5 and The plug plate 4 makes a linear motion to realize the opening and closing of the plug valve. When the cylinder 10 rotates to the position farthest from the plug valve housing 3, the cylinder 10 is located in the middle of the chute 6, and the plug valve is in the open state. When the cylinder 10 rotates to the position closest to the plug valve housing 3, the cylinder 10 is located in the middle of the chute 6, and the plug valve is in the closed state. The material brought out of the plug valve housing 3 due to the opening of the plug plate 4 can be observed through the transparent upper cover 11. When there is a lot of material, open the lower cover 12 for cleaning.

[0019] The above description is only a preferred embodiment of the present invention, which is only used to facilitate the explanation of the present invention and does not impose any form of limitation on the present invention. Any person with ordinary knowledge in the technical field, if it does not depart from the scope of the technical features of the present invention, uses the equivalent embodiments made by partial changes or modifications of the technical content disclosed in the present invention, and does not depart from the technical features of the present invention, all still fall within the scope of the technical features of the present invention.
