Description

Technical Field

[0001] This utility model relates to the technical field of gas valves, specifically a gas valve with a flow diversion and pressure stabilization structure. Background Technology

[0002] A gas valve is a device used to control the flow of gas. Its main function is to adjust and control the flow rate, pressure and direction of the gas medium according to the gas transmission requirements, thereby ensuring the normal operation and safety of the entire gas transmission system. It is widely used in the safe transportation of gas.

[0003] As disclosed in announcement number CN216306866U, a gas diversion shut-off valve includes a valve body and a diversion assembly. A valve cover is installed at the upper center of the valve body, and a valve stem is located at the center of the valve cover. An operating disc is located above the valve stem, and a sealing assembly for sealing the valve stem is fixed around the lower perimeter of the operating disc. The sealing assembly includes an additional metal sleeve, a magnetic ring, and a telescopic sealing sleeve, with the magnetic ring connected to the inner perimeter of the additional metal sleeve. The filter mesh of this gas diversion shut-off valve has a pleated structure. This structure design provides a larger contact area with the gas compared to a planar filter, which is beneficial for increasing the gas flow rate and the adsorption performance for foreign matter. The hollow tube is bonded to the inner wall of the valve body by an absorbent cotton sheet. Adhesive is injected into the absorbent cotton sheet using a syringe, allowing the cotton sheet to absorb the adhesive and solidify, thereby enhancing the sealing and firmness between the hollow tube and the inner wall of the valve body.

[0004] However, in the existing technology, it is inconvenient to monitor the pressure of the gas. It can only divert the transported gas, but the flow rate of the diverted gas is not easy to adjust and the stability is poor. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose a gas valve with a flow diversion and pressure stabilization structure. Summary of the Invention

[0006] The purpose of this invention is to provide a gas valve with a flow-diversion and pressure-stabilizing structure to solve the problems mentioned in the background art, such as the inconvenience of monitoring the gas pressure, the inability to divert the transported gas, the difficulty in adjusting the flow rate of the diverted gas, and the poor stability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gas valve with a flow diversion and pressure stabilization structure, comprising a valve body, an inlet pipe disposed at the upper end of the valve body, and two gas diversion pipes disposed at the lower end of the valve body;

[0008] Also includes:

[0009] A connecting bend is provided, the upper end of which is connected to the air intake pipe, and the lower end of which is connected to the air intake pipe. The connecting bend is connected to the valve body through the air intake pipe.

[0010] A flow regulating component is used to block and adjust the gas flow rate, and the flow regulating component is symmetrically arranged on the left and right sides of the valve body.

[0011] Preferably, a first pressure gauge is installed in the middle of the air intake pipe, and a second pressure gauge is installed in the middle of the gas diversion pipe.

[0012] Preferably, the flow regulating component is composed of a sealing plug that is slidably connected to the left and right sides inside the valve body and a movable regulating column that is fixedly connected to the middle of the sealing plug.

[0013] Preferably, the sealing plug is fitted to the inner side of the valve body, and the length of the sealing plug is greater than the inner diameter of the connecting bend.

[0014] Preferably, the movable adjusting column and the valve body form a left-right sliding structure, and the lower end of the movable adjusting column is provided with multiple fixing grooves for positioning at equal intervals.

[0015] Preferably, movable plates are slidably connected to the upper ends of both the left and right sides of the valve body, and a spring is provided between the upper end of the movable plate and the outer side of the valve body. A protrusion for limiting the position is fixedly connected to the inner side of the lower end of the movable plate, and the movable plate drives the protrusion to be inserted into the fixed groove at the corresponding position.

[0016] Preferably, a limiting plate is fixedly connected to the upper side of the movable plate, and the limiting plate and the valve body are locked together by a limiting bolt that passes through the lower end of the limiting plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: The gas valve with a diversion and pressure stabilization structure allows the gas transported in the inlet pipe to enter the gas diversion pipe for diversion through the connecting bend and the inlet pipe. Moreover, the pressure of the gas can be monitored by combining the first pressure gauge and the second pressure gauge. The sealing plug can also be extended and retracted in the valve body by the movable adjusting column to block the opening at the lower end of the connecting bend or adjust the size of the gas outlet, thereby facilitating the adjustment of the flow rate after gas diversion. After the adjustment is completed, the sealing plug can be fixed in the valve body by the movable plate driving the protrusion to be inserted into the corresponding fixing groove.

[0018] 1. It is equipped with a connecting bend, a first pressure gauge and a second pressure gauge. The connecting bend connects the valve body, the inlet pipe and the gas split pipe, which facilitates the splitting of gas. The first pressure gauge and the second pressure gauge facilitate the monitoring of the gas pressure.

[0019] 2. A flow regulating component is provided, which includes a sealing plug and a movable regulating column. The movable regulating column drives the sealing plug to slide and extend in the valve body, thereby blocking the connecting bend and adjusting the opening size, thus facilitating the adjustment of the gas flow rate.

[0020] 3. It is equipped with a movable plate, a limit plate, and a limit bolt. The movable plate drives the protrusion to engage in the fixed groove, which facilitates the limiting of the movable adjusting column and the valve body. Moreover, the limit plate and limit bolt can lock the movable plate to prevent accidental contact with the movable plate from affecting the stability of the sealing plug in the valve body.

[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 see Figures 1-7 .

[0031] To address the problems in existing technologies where it is inconvenient to monitor gas pressure and only the delivered gas can be diverted, but the flow rate of the diverted gas is difficult to adjust and the stability is poor, this solution provides a gas valve with a diversion and pressure stabilization structure. The valve comprises a valve body 1, an inlet pipe 2 located at the upper end of the valve body 1, and two gas diversion pipes 4 located at the lower end of the valve body 1. The upper end of a connecting bend 3 is connected to the inlet pipe 2, and the lower end of the connecting bend 3 is also connected to the inlet pipe 2. The connecting bend 3 is connected to the valve body 1 via the inlet pipe 2. A flow regulation component 7 is used to block and regulate the gas flow rate, and the flow regulation component 7 is symmetrically arranged on the left and right sides of the valve body 1.

[0032] like Figure 1 and Figure 2 As shown, an air inlet pipe 2 is fixed at the upper end of the valve body 1, and two gas diversion pipes 4 are fixed at the lower end of the valve body 1. The air inlet pipe 2 is connected to the valve body 1 through a connecting bend pipe 3. When conveying gas, the gas enters the valve body 1 through the air inlet pipe 2 and then is diverted and conveyed outward through the gas diversion pipes 4. A first pressure gauge 5 is installed in the middle of the gas diversion pipe 4, and a second pressure gauge 6 is installed in the middle of the air inlet pipe 2. By setting the first pressure gauge 5 and the second pressure gauge 6, the pressure of the gas can be adjusted, and the flow rate of the gas can be better adjusted.

[0033] When it is necessary to adjust the gas flow rate, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the flow regulating component 7 is composed of sealing plugs 8 slidably connected to the left and right sides inside the valve body 1 and a movable adjusting column 9 fixedly connected to the middle of the sealing plugs 8. The sealing plugs 8 are fitted against the inner wall of the valve body 1. First, the limiting bolt 15 is rotated to loosen the limiting plate 14. Then, by pressing down the movable plate 10, the movable plate 10 slides between itself and the valve body 1, and the movable plate 10 compresses the spring 11, causing the spring 11 to undergo elastic deformation. At this time, the movable plate 10 drives the protrusion 12 to move downward and move out of the fixed groove 13, thereby loosening the limiting between the movable adjusting column 9 and the valve body 1. Then, the movable adjusting column 9 is pulled to the left or right, and the movable adjusting column 9 slides between itself and the valve body 1. The movable adjusting column 9 pushes the sealing plugs 8 to move in and out of the valve body 1. By moving the sealing plugs 8 inside the valve body 1, the sealing plugs 8 can block the opening at the lower end of the connecting bend 3, or adjust the area of ​​the opening at the lower end of the sealing plugs 8, thereby adjusting the gas flow rate.

[0034] After adjustment, release the movable plate 10 directly. At this time, the spring 11 returns to its elastic deformation and pushes the movable plate 10 to move upward. The movable plate 10 drives the protrusion 12 to engage in the fixing groove 13 at the corresponding position at the lower end of the movable adjusting column 9, which facilitates the limiting of the movable adjusting column 9 and the valve body 1. Then, the limiting bolt 15 can be rotated to limit the limiting plate 14 and the valve body 1. By limiting the limiting plate 14, the movable plate 10 can be locked to prevent accidental contact of the movable plate 10 and loosening of the movable adjusting column 9, thereby improving the stability of the sealing plug 8 in the valve body 1.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
