Description

A valve with an opening and closing auxiliary device Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a valve with an opening and closing auxiliary device. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications. A search revealed that the existing public technology publication number is CN209959917U, which describes a valve with good antifreeze effect, including a rubber sealing plug, connecting column, mesh plate, valve shell, opening and closing parts, insulation cotton filling block, valve column, rotary table, insulation material filling, sealing ring, lifting screw, base plate, sealing ring, positioning nut, insulation box, input and output pipes, and insulation liquid storage box. This invention provides through holes at both ends of the valve, and rubber sealing plugs are installed in the through holes. When the ambient temperature is low, the positioning nut can be rotated in advance to pull the rubber sealing plugs out from the inlet and outlet ports at both ends of the valve shell, ensuring that the incoming liquid is discharged quickly. This prevents backflow liquid from accumulating in the inner cavity of the closed valve, which could cause the valve's opening and closing parts to freeze or directly freeze and block the valve's interior, making the valve unable to adapt to pipeline blockage.

[0003] In summary, while the valves installed in the above cases solve the problem of freezing, the manual rotation of the valves in the above solutions not only makes opening and closing cumbersome, but may also cause the turntable to corrode and rust over time, making it difficult to rotate and open by hand. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a valve with an opening and closing auxiliary device, so as to solve the problem that when the valve in the above-mentioned solution proposed in the background technology is opened and closed manually, it is not only troublesome to open and close, but also may cause the turntable to corrode and rust over a long period of time, making it difficult to open and close manually.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a valve with an opening and closing auxiliary device, comprising a valve body structure, wherein a protective structure is provided above the valve body structure;

[0006] The valve body structure includes a valve body through which a connecting plate is fixedly installed, and a drive gear is fixedly installed through the handwheel on the valve body. At the same time, a fixing plate with a sliding groove is fixedly installed on the rear side above the connecting plate.

[0007] A connecting seat is fixedly installed above the connecting plate, and the connecting seat has a through hole.

[0008] By adopting the above technical solution, a fixed installation can be achieved through the connection seat.

[0009] Preferably, a connecting plate with through holes and connecting grooves is fixedly installed on one side of the connecting seat, and an electric telescopic rod is fixedly installed on the other side of the connecting seat, while a drive rack is fixedly installed at the output end of the electric telescopic rod.

[0010] By adopting the above technical solution, the electric telescopic rod is used to control and drive the adjustment.

[0011] Preferably, a limiting rod that is inserted into a through hole is fixedly installed at one end of the drive rack, and another drive rack is mounted on the surface of the fixing plate by means of a sliding groove and a slider, while another limiting rod is fixedly installed on one side of the other drive rack.

[0012] By adopting the above technical solution, the insertion limit is achieved by setting a limit rod.

[0013] Preferably, the protective structure includes a cover with a handle fixedly mounted on its surface, and a matching plate fixedly mounted inside the cover, while a connecting block with a through hole is fixedly mounted on one side of the matching plate.

[0014] By adopting the above technical solution, the connecting blocks are designed to facilitate opening and sliding.

[0015] Preferably, the drive rack is provided in one set, and the drive rack is configured for relative sliding adjustment.

[0016] By adopting the above technical solution, the meshing drive adjustment is achieved through the setting of the drive rack.

[0017] Preferably, the sliders are provided in one group and are arranged symmetrically.

[0018] By adopting the above technical solution, the slider is designed to provide both fixation and sliding functionality.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the valve with an opening and closing auxiliary device,

[0020] (1) This case solves the problem that when the valve is manually rotated to open and close, it is not only troublesome to open and close, but also may cause the turntable to corrode and rust over a long period of time, making it difficult to rotate and open by manpower alone. When the handwheel cannot be turned manually, the electric telescopic rod is controlled to operate. At this time, the electric telescopic rod drives the rack to move. When the rack is driven by force, it drives the gear to rotate, thereby driving the handwheel to rotate synchronously. When the handwheel is rotated, the valve is opened and closed by rotation.

[0021] (2) By setting up a protective structure, the problem of handwheel corrosion and rust is easily caused when the handwheel is exposed to the external environment for a long time. The handwheel is protected by wrapping it with a cover, thus avoiding the handwheel being exposed to the external environment for a long time.

[0022] (3) By setting up: driving gear, driving rack, limit rod, connecting groove, connecting plate, matching plate and connecting block, the problem of easy opening and closing of the cover is solved. When the cover wraps the handwheel and the operator controls the electric telescopic rod to operate, the limit rod is driven to insert into the connecting groove, connecting plate, matching plate and connecting block. At this time, it is not only convenient to close the valve body, but also convenient to limit the insertion of the cover. When the limit rod slides relative to the connecting groove, connecting plate, matching plate and connecting block, it is convenient to rotate and open the valve body. Attached Figure Description

[0029] 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.

[0030] Please refer to Figures 1-5. This utility model provides a technical solution: a valve with an opening and closing auxiliary device, as shown in Figures 1, 2, 3, and 5. It includes a valve body structure 1, which comprises a valve body 101 with a connecting plate 102 fixedly mounted through it at the top. A drive gear 103 is fixedly mounted through a handwheel on the valve body 101. A fixing plate 104 with a sliding groove 105 is fixedly mounted on the rear side above the connecting plate 102. A connecting seat 106 is fixedly mounted above the connecting plate 102, and the connecting seat 106 has a through hole. A connecting plate 108 with a through hole and a connecting groove 107 is fixedly mounted on one side of the connecting seat 106, and an electric telescopic rod 109 is fixedly mounted on the other side of the connecting seat 106. The output end of the electric telescopic rod 109 is fixedly equipped with a drive rack 1010. There is one set of drive racks 1010, and the drive racks 1010 adopt a relative sliding adjustment setting. When the above-mentioned components are set with two racks, it not only reflects the fixed installation and force-bearing sliding adjustment of the above-mentioned components, but also reflects the practicality of the installation setting and the mutual driving adjustment of the force. At the same time, when the drive racks 1010 adopt the relative sliding adjustment setting, it effectively drives the limit rods 1011 to slide and insert into each other. The valve body 101 adopts the component settings in the comparative document. When the component settings in the comparative document are used, it effectively achieves the normal anti-freeze conveying effect.

[0031] Furthermore, in the above scheme, a limiting rod 1011 is fixedly installed at one end of the drive rack 1010 and inserted into the through hole. Another drive rack 1010 is slidably installed on the surface of the fixing plate 104 through the sliding groove 105 and the slider 1012. There is one set of sliders 1012, and the sliders 1012 are arranged symmetrically. When there are two sets of the above components, it not only reflects the symmetry of the installation of the above components, but also reflects the sliding matching of the installation of the above components. Furthermore, when there are two sets of the above components, it reflects the symmetry of the above components about the axis of the drive rack 1010. At the same time, another limiting rod 1011 is fixedly installed on one side of the other drive rack 1010.

[0032] As shown in Figure 4, a protective structure 2 is provided on the top of the valve body structure 1. The protective structure 2 includes a cover 201 with a handle 202 fixedly installed on its surface, and a matching plate 203 is fixedly installed inside the cover 201. At the same time, a connecting block 204 with a through hole is fixedly installed on one side of the matching plate 203.

[0033] In the above scheme, when the valve body 101 needs to be opened or closed, the operator controls the electric telescopic rod 109 to operate. At this time, the electric telescopic rod 109 drives the drive rack 1010 to move. When the drive rack 1010 is subjected to force, it drives the gear 103 to rotate, thereby driving the handwheel to rotate synchronously. When the handwheel is subjected to force and rotates, it rotates the valve body 101 to open or close. During the opening and closing process of the valve body 101, the cover 201 covers and protects the handwheel above the valve body 101 and the components inside the cover 201 throughout the process.
