Description

Technical Field

[0001] The utility model relates to the technical field of lifting valve equipment, in particular to a horizontal push type lifting valve structure. Background Art

[0002] The horizontal push type lifting valve is also called a push valve or a push plate valve. It is a type of lifting valve. It is suitable for occasions where pressure and flow requirements are not high. It has the advantages of simple structure, low cost, and easy operation. Compared with butterfly valves and gate valves, the push valve has a lower leakage rate and can be opened or closed quickly. It is suitable for application scenarios that require quick response.

[0003] However, in the existing use of horizontal push valves, the valve plate is usually pushed by a single push rod connected to the valve plate through a cylinder or an electric push rod. This method will cause greater wear and tear on the push rod due to factors such as the gravity of the valve plate during long-term use. At the same time, the electric telescopic rod or cylinder as a driving device will cause damage to these driving sources if it continuously pushes heavy objects, increasing energy consumption.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original lifting valve. Utility Model Content

[0005] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution with a horizontal push-type lifting valve structure that is significantly different from the existing technology to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a horizontal push-type lifting valve structure, including a box body, a sealing valve seat is installed on one side of the box body, and a docking tube connected to the sealing valve seat is installed on the outer wall of the box body on this side, a valve plate is connected to the sealing valve seat, and at least two push rods are connected to the valve plate at equal angles, each of the push rod ends is located in the corresponding cylinder, and the cylinder is installed on both sides of one end surface of the outer wall of the box body, and a plurality of sealing boxes are connected to the push rod on the other side of the inner wall of the box body, each of the cylinder ends is connected to a connecting pipe, and the connecting pipe is connected to the effort-saving pushing structure, and the end of the effort-saving pushing structure is rotatably connected to an electric telescopic rod, and the electric telescopic rod is rotatably connected to the outer wall of the box body on this side.

[0007] Preferably, a group of sealing rings are provided on the sealing valve seat in the area where it interfaces with the valve plate.

[0008] Preferably, the push rod and the cylinder are in a snap-fitting and sliding connection, and the push rod is located at the inner end of the cylinder and is a piston structure.

[0009] Preferably, the effort-saving pushing structure includes an oil cylinder, a piston plate, a movable rod, a connecting rod, a support rod and a bracket. The outer wall of the box body is connected to the oil cylinder, and a piston plate is provided in the oil cylinder. The piston plate is connected to the movable rod, and the end of the movable rod passes through the outer wall of the oil cylinder and is rotatably connected to the connecting rod. The end of the connecting rod is rotatably connected to the support rod, and the outer wall of the support rod is rotatably connected to the bracket. The bracket is installed on the outer wall of the oil cylinder, and the end of the support rod is rotatably connected to the electric telescopic rod.

[0010] Preferably, the volume of the oil cylinder is much larger than the volume of the cylinder body, and the cylinder body is symmetrically distributed about the oil cylinder.

[0011] Preferably, the connection fulcrum between the bracket and the support rod is close to the end where the support rod is connected to the connecting rod.

[0012] Compared with the prior art, the beneficial effect of the utility model is that the horizontal push-type lifting valve structure can more effectively balance the weight of the valve plate through the double push rods symmetrically arranged on both sides of the valve plate compared with the conventional single push rod, avoiding damage or deformation caused by uneven force. In addition, the design of the double push rod can also improve the stability and reliability of the entire system and ensure the normal operation of the valve. In short, this arrangement of the valve plate and the push rod can not only extend the service life of the push rod, but also improve the working efficiency and safety performance of the valve.

[0013] The electric telescopic rod can amplify the force through the lever principle without applying excessive force by cooperating with the push rod, cylinder, connecting pipe and other components, thereby pushing the piston plate to press the hydraulic oil in the cylinder into the cylinder. This design cleverly uses the lever principle to achieve a larger output force under a smaller input force, thereby reducing the driving energy consumption of the electric telescopic rod.

[0014] At the same time, this design also reduces damage to the electric telescopic pole itself because it does not need to withstand excessive force, which helps to improve the service life and working efficiency of the electric telescopic pole. BRIEF DESCRIPTION OF THE DRAWINGS
