Description

Technical Field

[0001] This utility model relates to a mechanical valve, specifically a novel mechanical valve structure. Background Technology

[0002] Mechanical valves are devices that control the flow direction or pressure of fluid media through mechanical structures. They are mainly used in pipeline systems to regulate parameters such as flow rate, pressure, and temperature of fluids.

[0003] Existing mechanical valves have complex structures and unreasonable designs. The valve stem and valve disc are typically coaxially connected, with the valve stem rotating to drive the valve disc in a coaxial motion. However, this adjustment method results in low efficiency in adjusting the valve disc by the valve stem, and the time required to open and close the valve through disc rotation is relatively long. Furthermore, mechanical valves usually have only one flow path, thus allowing fluid media to be transported in only one direction, not in two different directions. Therefore, the inventors have improved the structure of the mechanical valve. Utility Model Content

[0004] The purpose of this utility model is to provide a novel mechanical valve structure. This mechanical valve structure has the advantages of simple structure, reasonable design, and the ability to drive the spherical valve disc to rotate eccentrically, allowing the valve disc to rotate faster, making the valve disc adjustment more rapid and the adjustment efficiency higher. It ensures that the mechanical valve structure can achieve faster opening and closing, and can realize the transportation of fluid media in two different directions, thus solving the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel mechanical valve structure, comprising a valve body and a driving device mounted on the valve body. The valve body includes a base, a valve seat fixed to the base, and a valve cover fixed to the valve seat. A bottom flow channel is provided through the base, and a side flow channel is provided through the valve seat. The side flow channel has two openings symmetrically arranged on the valve seat. A valve disc is provided below the driving device, and the driving device includes a fixing seat fixed to the valve cover. A bearing is mounted on the seat, and a valve stem is mounted on the bearing. A rotating platform and a drive block are arranged sequentially below the valve stem. The valve stem is vertically arranged and passes through the valve cover from top to bottom and is connected to the rotating platform. The drive block is fixed to the lower end face of the rotating platform, and the drive block and the rotating platform are designed to be eccentrically connected. The valve disc is located below the drive block and is fixedly connected to the drive block. An adapter groove is provided on the top of the valve disc. The drive block fits into the adapter groove and is fixed in the adapter groove, so that when the drive block rotates, it can drive the valve disc to rotate eccentrically.

[0006] Preferably, the bottom flow channel is vertically arranged and communicates with the side flow channel, while the side flow channel is horizontally arranged.

[0007] Preferably, a deflecting channel is provided through the valve disc, the deflecting channel has two openings, one of which communicates with the bottom channel and the other with the side channel, and the two openings of the deflecting channel are distributed on the side and bottom of the deflecting channel.

[0008] Preferably, the end of the valve stem away from the rotary table is positioned above the valve cover, and a handle is fixed to the valve stem. The end of the handle away from the valve stem is tilted upwards, and the handle is for human hand gripping.

[0009] Preferably, the valve disc is spherical and is installed inside the valve seat, with the valve disc positioned between the openings on both sides of the side flow channel.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a novel mechanical valve structure, which includes a valve body and a drive device mounted on the valve body. The overall structure is simple and rationally designed. A valve disc is located below the drive device, and the drive device includes a fixed seat fixed to the valve cover. A bearing is mounted on the fixed seat, and a valve stem is mounted on the bearing. A rotating platform and a drive block are sequentially arranged below the valve stem. The drive block is fixed to the lower end face of the rotating platform, and the drive block and the rotating platform are eccentrically designed. The valve disc is located below the drive block and is fixedly connected to the drive block. By setting an eccentric fitting groove on the valve disc and setting an eccentric drive block below the valve stem, when the operator turns the handle to rotate the valve stem, it can drive the spherical valve disc to rotate eccentrically, allowing the valve disc to rotate faster, making the valve disc adjustment more rapid and the adjustment efficiency higher. This ensures that the mechanical valve structure can achieve faster opening and closing, and has strong practicality.

[0011] 2. The valve body of this utility model includes a base, a valve seat fixed on the base, and a valve cover fixed on the valve seat. A bottom flow channel is provided through the base, and a side flow channel is provided through the valve seat. The side flow channel has two openings. A turning flow channel is provided through the valve disc. The turning flow channel has two openings, one of which communicates with the bottom flow channel and the other with the side flow channel. The two openings of the turning flow channel are distributed on the side and bottom of the turning flow channel. When the valve disc rotates, it can drive the turning flow channel to change from communicating with one side of the side flow channel to communicating with the other side of the side flow channel, quickly switching the output direction of the fluid medium. This allows the mechanical valve structure to realize the delivery of fluid medium in two different directions, making it more widely applicable and suitable for widespread use.

[0022] Please see Figure 2 The valve body 1 includes a base 11, a valve seat 12 fixed on the base 11, and a valve cover 13 fixed on the valve seat 12. A bottom flow channel 111 is provided through the base 11, and a side flow channel 121 is provided through the valve seat 12. The side flow channel 121 has two openings, which are symmetrically arranged on the valve seat 12. The bottom flow channel 111 is vertically arranged and communicates with the side flow channel 121. The side flow channel 121 is horizontally arranged. A valve disc 3 is arranged below the drive device 2, and the drive device 2 includes a fixed seat 21 fixed on the valve cover 13. A bearing is installed on the fixed seat 21, and a valve stem 22 is installed on the bearing. A rotating table 23 and a drive block 24 are arranged sequentially below the valve stem 22.

[0023] Please refer to it again. Figure 2 The valve disc 3 is located below the drive block 24 and is fixedly connected to the drive block 24. A turning channel 31 is provided through the valve disc 3. The turning channel 31 has two openings. One of the openings of the turning channel 31 is connected to the bottom channel 111, and the other opening is connected to the side channel 121. The two openings of the turning channel 31 are distributed on the side and bottom of the turning channel 31. When the valve disc 3 rotates, it can drive the turning channel 31 to change from being connected to one side of the side channel 121 to being connected to the other side of the side channel 121, quickly switching the output direction of the fluid medium. This allows the mechanical valve structure to realize the delivery of fluid medium in two different directions, making it more widely applicable.

The end of the valve stem 22 away from the rotating platform 23 is located above the valve cover 13, and a handle 25 is fixed on the valve stem 22. The end of the handle 25 away from the valve stem 22 is inclined upward. The handle 25 is for people to hold. When the person turns the handle 25 to drive the valve stem 22 to rotate, it can drive the spherical valve disc 3 to rotate eccentrically, so that the valve disc 3 rotates faster, making the adjustment of the valve disc 3 more rapid and the adjustment efficiency higher, ensuring that the mechanical valve structure can achieve faster opening and closing.

[0025] Please see Figure 4 An adapter groove 32 is provided on the top of the valve disc 3. The drive block 24 is inserted into the adapter groove 32 and fixed in the adapter groove 32, so that when the drive block 24 rotates, it can drive the valve disc 3 to rotate eccentrically.
