Description

Technical Field

[0001] This utility model relates to the field of industrial gas consumption management technology, specifically to an industrial gas consumption management device. Background Technology

[0002] In industrial production processes, industrial gas management equipment is a core system ensuring the efficient and safe utilization of gas energy, and it is widely used in many fields such as chemical engineering, metallurgy, electronics, food processing, and automobile manufacturing. Among them, the gas flow control valve, as a key actuator in industrial gas management equipment for regulating and controlling gas output, directly affects the stability of gas flow and pressure, as well as the safety of the production process. Its performance is of great significance to production efficiency, product quality, and operational safety.

[0003] Currently, the gas control valves used in industrial gas volume management equipment are mostly manually operated valves, which are operated by hand rotation, due to considerations such as cost control, structural simplicity, and intuitive operation. These manually operated valves typically include a valve body, valve core, valve stem, and handle. Manually rotating the handle causes the valve stem and valve core to rotate, changing the on / off state or flow area of ​​the internal flow channels between the valve core and valve body, thereby achieving the opening, closing, or flow regulation of gas output.

[0004] However, in actual industrial production, emergencies such as equipment failure, gas leaks, and overpressure often occur. In these situations, it is necessary to quickly shut off the gas output to prevent the accident from escalating and to ensure the safety of personnel and equipment. However, existing manual rotary gas control valves have significant operational defects in emergency situations: because their closing action relies on manual reverse rotation of the handle, and to ensure sealing performance, there is usually a certain resistance between the valve core and the valve body, the operator needs to apply a large force to achieve complete closure. This process often takes several seconds or even longer. In scenarios involving flammable gases, toxic gases, or high-pressure gases, this short time difference may lead to increased leakage, increased risk of fire and explosion, or the spread of toxic gases, seriously threatening production safety. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an industrial gas consumption management device, which solves the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an industrial gas volume management device, comprising a valve body, a mounting base, a support component, a valve stem, and a handle;

[0007] The mounting base is disposed on the valve body, the support member is mounted on the mounting base, the valve stem is rotatably connected to the inside of the support member through a bearing, and the bottom end of the valve stem passes through the mounting base and extends into the inside of the valve body, and a valve plate located inside the valve body is installed at the bottom end of the valve stem.

[0008] The handle is located on the outside of the valve stem, and a rectangular post is integrally formed on the outside of the valve stem and above the support member. The handle is located on the outside of the rectangular post, and a rectangular through hole adapted to the rectangular post is opened inside the handle.

[0009] A connecting ring is sleeved on the outside of the valve stem, and a torsion spring is assembled between the connecting ring and the mounting base. The two ends of the torsion spring are respectively fixedly connected to the connecting ring and the torsion spring.

[0010] A locking assembly is provided between the handle and the support member to lock the handle to the support member.

[0011] Furthermore, the support member includes two uprights and a connecting plate;

[0012] Both uprights are vertically mounted on the mounting base, and the connecting plate is located on the outside of the two uprights.

[0013] Furthermore, the valve stem is rotatably connected to the connecting plate via a bearing.

[0014] Furthermore, the torsion spring is sleeved on the outside of the valve stem.

[0015] Furthermore, a limiting ring is fitted on the outer side of the valve stem, and the limiting ring is located above the connecting plate.

[0016] Furthermore, the locking assembly includes a sleeve installed at the bottom end of the handle;

[0017] A plurality of toothed grooves are provided on the outer side of the sleeve. Corresponding to the toothed grooves, a mating ring is provided on the upper surface of the connecting plate. The inner side of the mating ring is provided with a toothed groove that matches the toothed grooves.

[0018] Furthermore, the length of the rectangular post is greater than the depth of the rectangular through hole, so that the handle can move up and down on the outside of the rectangular post.

[0019] Furthermore, the sleeve is fitted onto the outside of the rectangular column, and a limiting nut is threaded onto the top of the valve stem.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] 1. This industrial gas volume management equipment uses a traditional manual control valve that requires multiple reverse rotations to close. However, this equipment uses the elastic potential energy of a torsion spring and a fast unlocking design of the locking component to shorten the emergency closing time from several seconds to less than one second. This effectively reduces gas leakage in emergencies and lowers the risk of fire and explosion.

[0022] 2. This industrial air volume management device features a locking component with a toothed and toothed meshing structure, which, together with the support component, provides stable support for the valve stem. This avoids air volume fluctuations caused by vibration or accidental contact in traditional control valves. At the same time, the transmission design of the rectangular column and rectangular through hole eliminates slippage, making air volume adjustment more precise and improving the stability of the production process.

[0027] 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.

[0028] Please see Figure 1-3 An industrial gas volume management device in this embodiment includes a valve body 1, a mounting base 2, a support 3, a valve stem 4, a handle 5, a rectangular column 6, a connecting ring 7, a torsion spring 8, a locking assembly 9, and a limiting nut 10. The main channel for gas flow is provided with a valve plate connected to the bottom end of the valve stem 4.

[0029] The valve body 1, with its valve plate rotating, can change the on / off state or flow area of ​​the internal flow channel, thereby regulating the air volume. The mounting base 2 is fixed to the top of the valve body 1, serving as both the mounting base for the support component 3 and providing a through channel for the valve stem 4, allowing the valve stem 4 to extend stably into the valve body 1. The valve stem 4 is connected to the mounting base 2 via a sealed bearing.

[0030] In detail, the support 3 consists of two uprights 301 and a connecting plate 302. The two uprights 301 are welded parallel and vertically to the mounting base 2. The connecting plate 302 is horizontally fixed to the top of the two uprights 301 to form a portal support structure. The center of the connecting plate 302 is rotatably connected to the valve stem 4 through a bearing to provide radial support for the valve stem 4 and reduce shaking during rotation.

[0031] Furthermore, the valve stem 4 is a through-type long rod structure. Its bottom end passes through the mounting base 2 and is fixedly connected to the valve plate inside the valve body 1. Its top end extends to the top of the connecting plate 302. A rectangular column 6 is integrally formed on the outer side of the valve stem 4 above the connecting plate 302. A limit nut 10 is threaded onto the rod body above the rectangular column 6 to limit the vertical movement range of the handle 5. In addition, a limit ring is also sleeved on the outer side of the valve stem 4. The limit ring is located above the connecting plate 302 to limit the vertical movement range of the handle 5.

[0032] Furthermore, the handle 5 is fitted onto the outside of the rectangular post 6, and a rectangular through hole adapted to the rectangular post 6 is opened inside it. Since the length of the rectangular post 6 is greater than the depth of the rectangular through hole, the handle 5 can slide up and down along the rectangular post 6. When the handle 5 moves downward, the locking component 9 at its bottom end engages with the support 3. When it moves upward, the locking component 9 disengages, thereby unlocking the device.

[0033] Specifically, the connecting ring 7 is fixedly sleeved on the outside of the valve stem 4, located between the mounting base 2 and the connecting plate 302. Its outer wall is welded to one end of the torsion spring 8, and the other end of the torsion spring 8 is welded to the top of the mounting base 2. The torsion spring 8 is entirely sleeved on the outside of the valve stem 4.

[0034] In actual use, when the valve stem 4 rotates, the connecting ring 7 rotates synchronously with it, causing the torsion spring 8 to deform and store elastic potential energy, providing the valve stem 4 with the reset power. When the lock is released, the elastic force of the torsion spring 8 can drive the valve stem 4 to rotate rapidly, realizing the emergency closure of the valve plate.

[0035] More specifically, the locking assembly 9 consists of a sleeve 901 and a mating ring 902. The sleeve 901 is vertically fixed to the bottom end of the handle 5, and several toothed grooves are evenly provided on its outer side. The mating ring 902 is fixed to the upper surface of the connecting plate 302 corresponding to the position of the sleeve 901, and toothed grooves that match the toothed grooves are provided on its inner side.

[0036] In actual use, when the handle 5 moves downward, the toothed groove of the sleeve 901 engages with the toothed groove of the mating ring 902, thereby locking the handle 5 and the support 3. When the handle 5 moves upward, the toothed groove separates from the support 3, and the lock is released.

[0037] The working principle of the above embodiments is as follows:

[0038] (1) In the daily gas volume adjustment state, the handle 5 is in the downward pressing state, the tooth groove of the sleeve 901 of the locking component 9 is fully engaged with the tooth groove of the docking ring 902, and the valve stem 4 and the handle 5 are fixed in the current position. When the gas volume needs to be adjusted, the operator rotates the handle 5. Through the transmission of the rectangular column 6 and the rectangular through hole, the valve stem 4 and the valve plate in the valve body 1 are driven to rotate synchronously. At the same time, the valve stem 4 drives the connecting ring 7 to rotate, so that the torsion spring 8 is deformed and stores elastic potential energy. After the adjustment is completed, the handle 5 is pressed down, the tooth groove of the locking component 9 re-engages with the tooth groove, and the valve stem 4 and the valve plate remain in the adjusted position to achieve stable control of the gas volume.

[0039] (2) When encountering emergencies such as gas leakage or overpressure, the operator does not need to rotate the handle 5 in the opposite direction. He only needs to lift the handle 5 upwards to disengage the tooth groove of the sleeve 901 from the tooth groove of the docking ring 902. At this time, the elastic potential energy stored in the torsion spring 8 is released quickly, driving the connecting ring 7 and the valve stem 4 to rotate rapidly in the opposite direction. The valve stem 4 drives the valve plate in the valve body 1 to rotate to the closed position, realizing the instantaneous cut-off of gas volume, which is much shorter than the closing time of the traditional manual control valve.
