Description

Technical Field

[0001] This utility model relates to the technical field of fuel control valves, specifically to a shared control valve for fuel oil and gas in a stove. Background Technology

[0002] Stoves are generally equipped with corresponding control valves to control the opening and closing of the fuel passage and regulate the fuel flow. The control valve is mainly a ball valve consisting of a valve core that is rotated and mounted on the valve seat. An L-shaped guide hole is provided through the valve core. An L-shaped main feeding channel is provided on the control valve. When the two ends of the L-shaped guide hole coincide with the feed section and the discharge section of the L-shaped main feeding channel, respectively, the control valve is open; otherwise, the control valve is closed.

[0003] Due to the limited dimensions of the L-shaped through-hole and the L-shaped main feeding channel, and the small effective rotation angle of the ball valve, even a slight deviation can cause a large change in flow rate when adjusting the flow rate, resulting in poor control accuracy.

[0004] Therefore, the research objective of this utility model is to design a stove fuel oil and gas shared control valve that can improve the accuracy of controlling the firepower adjustment of the stove, thereby enhancing operational sensitivity and user experience. Utility Model Content

[0005] In view of the technical problems existing in the prior art, the present invention provides a stove fuel oil and gas common control valve, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is: A shared control valve for fuel oil and gas in a stove, comprising: The main tube has through holes extending through both ends of it; A guide pipe, which communicates with the through hole of the main body pipe and divides the main body pipe into a material guide pipe section and an installation pipe section; An adjusting component is movably installed within the installation pipe section to control the opening and closing of the material guide pipe section and adjust its diameter to precisely regulate the discharge flow rate.

[0007] The adjusting component is movably connected to the installation pipe section by means of threaded connection. The front end of the adjusting component is set as a small-diameter plugging rod and the middle part is set as a large-diameter threaded shaft. When the adjusting component is screwed into place, the plugging rod closes the material guide pipe section.

[0008] The end of the blocking rod is a gradually narrowing slope, and the end of the guide tube facing the installation tube section is a gradually widening slope.

[0009] The outer end of the adjusting component is axially limited and detachable by key teeth. When the handle is rotated, it drives the adjusting component to move inward and outward along the thread.

[0010] The handle has a through hole running through the front and back. A copper sleeve is installed in the through hole. An internal toothed key is provided in the copper sleeve. The outer end of the adjusting component has an external toothed key that matches the copper sleeve. The end of the adjusting component with the external toothed key has a threaded hole. The adjusting component is connected to the handle by screwing it through the copper sleeve.

[0011] A limiting mechanism for controlling the maximum rotation angle of the adjusting component is also provided between the handle and the adjusting component. The limiting mechanism includes a first limiting block and a second limiting block that are respectively fixedly installed on the installation pipe section and the handle. By adjusting the different installation angles of the handle (15) and the adjusting component (3), the travel distance between the first limiting block (501) and the second limiting block (502) can be adjusted, thereby realizing different movement distances of the adjusting component (3).

[0012] The main tube is integrally formed with a bypass pipe that connects its feed pipe section and flow pipe. A bypass control pipe is vertically connected to the bypass pipe. A corresponding first adjusting screw is movably and sealed inside the bypass control pipe. The rotation of the first adjusting screw is used to control the opening and closing of the bypass pipe and the adjustment of the flow rate.

[0013] The guide pipe is integrally formed and connected to a main control pipe. A corresponding second adjusting screw is movably and sealed inside the main control pipe. The rotation of the second adjusting screw is used to control the opening and closing of the guide pipe and the adjustment of the flow rate.

[0014] Each of the installation pipe section, main control pipe, and bypass control pipe is equipped with a sealing mechanism to ensure the sealing of the adjusting component, the second adjusting screw, and the first adjusting screw. The sealing mechanism includes a first sealing ring installed in the installation pipe section, main control pipe, or bypass control pipe, and a sealing screw installed at the end of the installation pipe section, main control pipe, or bypass control pipe via a threaded connection. After the sealing screw is installed in place, it is pressed onto the first sealing ring. Each adjusting component, the second adjusting screw, and the first adjusting screw has at least one recessed annular groove on its periphery. A corresponding second sealing ring is fitted in each recessed annular groove. The second adjusting screw and the first adjusting screw pass through the corresponding sealing screw and are connected to the corresponding main control pipe and bypass control pipe.

[0015] The outer side of the installation section of the main tube is integrally formed with at least one hanging lug, and the hanging lug is provided with a corresponding threaded hole. The common control valve is fixedly installed by the hanging lug and the screw.

[0016] Advantages of this utility model: 1) This utility model sets the valve body of the control valve as a main body pipe and a guide pipe that are connected. The guide pipe divides the main body pipe into a material guide pipe section and an installation pipe section. An adjusting component is installed and moved within the installation pipe section. By controlling the movement of the adjusting component in a step-by-step manner, the opening and closing of the material guide pipe section and the diameter of the material guide pipe section are controlled to adjust the flow rate of the feed. Furthermore, by installing the adjusting component through a threaded connection, the movement distance of the adjusting component can be controlled evenly, thereby accurately controlling the diameter of the material guide pipe section. Compared with ball valve type control valves, its adjustment accuracy and controllability are greatly improved.

[0017] 2) In this utility model, the front end of the adjusting component is set as a small-diameter plugging rod, and the end of the plugging rod is set as a gradually narrowing inclined surface. The end of the guide pipe section facing the installation pipe section is set as a gradually widening inclined surface. By coordinating the inclined surface setting with the movement of the adjusting component, the diameter of the guide pipe section can be controlled evenly and gradually, thereby gradually controlling the increase or decrease of the flow rate and further improving the uniformity of the flow rate adjustment.

[0018] 3) This utility model has a handle that can be axially detached and limited at the end of the adjusting component through key teeth, which facilitates the control of the rotation of the adjusting component. A limiting mechanism for controlling the maximum rotation angle is provided between the handle and the adjusting component. By adjusting the installation angle of the handle, the travel distance between the first limiting block on the installation pipe section and the second limiting block on the handle is controlled, thereby limiting the rotation angle of the handle and controlling the movement distance of the adjusting component, thereby controlling the maximum adjustable diameter of the feed pipe section, so as to limit the maximum fuel flow rate according to different usage scenarios and improve the usage effect.

[0019] 4) Traditional control valves have an "n"-shaped bypass channel on the inlet and outlet channels. The two ends of the bypass channel are connected to the inlet channel and the outlet channel, respectively. After the main channel is closed, fuel is supplied through the bypass channel to maintain the flame. However, due to the multiple bends in the "n"-shaped structure of the bypass channel, there is a certain resistance to the fuel flow, resulting in poor flow smoothness. Therefore, this utility model further connects a straight bypass pipe and a first adjusting screw for controlling the opening or closing of the bypass pipe between the L-shaped feed pipe section and the flow pipe. The straight bypass pipe reduces the bend angle, thereby reducing the pressure of fuel flow and improving the smoothness of fuel flow. Furthermore, the first adjusting screw is set perpendicular to the bypass pipe, which ensures that the fuel flow rate in the bypass pipes on both sides of the first adjusting screw is the same. This avoids turbulence caused by the different diameters on both sides of the first adjusting screw when it is in a half-open state, which would affect the smoothness of fuel flow.

Detailed Implementation

[0025] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-4 A shared control valve for fuel oil and gas in a stove, comprising: Main tube 1, wherein the main tube 1 is provided with through holes penetrating both ends thereof; The guide pipe 2 is connected to the through hole of the main pipe 1 and divides the main pipe 1 into a material guide pipe section 101 and an installation pipe section 102; Adjusting component 3 is movably installed inside the installation pipe section 102 and is used to control the opening and closing of the material guide pipe section 101 and adjust its diameter to precisely regulate the discharge flow rate.

[0026] The adjusting component 3 is movably connected to the installation pipe section 102 by means of threaded connection. The front end of the adjusting component 3 is configured as a small-diameter plugging rod 301 and the middle part is configured as a large-diameter threaded shaft 302. When the adjusting component 3 is screwed into place, the plugging rod 301 closes the material guide pipe section 101.

[0027] This invention configures the valve body of the control valve as a main body pipe 1 and a guide pipe 2 connected together. The guide pipe 2 divides the main body pipe 1 into a feed pipe section 101 and an installation pipe section 102. An adjusting component 3 is installed and moved within the installation pipe section 102. By controlling the movement of the adjusting component 3 in a step-by-step manner, the opening and closing of the feed pipe section 101 and the diameter of the feed pipe section 101 are controlled to adjust the feed flow rate. Furthermore, by installing the adjusting component 3 through a threaded connection, the movement distance of the adjusting component 3 can be controlled evenly, thereby accurately controlling the diameter of the feed pipe section 101. Compared with a ball valve control valve, its adjustment accuracy and controllability are greatly improved.

[0028] The end of the blocking rod 301 is a gradually narrowing slope, and the end of the guide tube section 101 facing the installation tube section 102 is a gradually widening slope.

[0029] In this invention, the front end of the adjusting member 3 is set as a small-diameter blocking rod 301, and the end of the blocking rod 301 is set as a gradually narrowing inclined surface. The end of the guide tube section 101 facing the installation tube section 102 is set as a gradually widening inclined surface. By cooperating with the inclined surface setting and the movement of the adjusting member 3, the diameter of the guide tube section 101 can be controlled evenly and gradually, thereby gradually controlling the increase or decrease of the flow rate and further improving the uniformity of the flow rate adjustment.

[0030] The outer end of the adjusting member 3 is axially limited and detachable by key teeth and a handle 15 is installed. When the handle 15 rotates, it drives the adjusting member 3 to move inward and outward along the thread.

[0031] The handle 15 is provided with a through hole 1501 extending from front to back. A copper sleeve 4 is installed in the through hole 1501. An internal toothed key is provided in the copper sleeve 4. The outer end of the adjusting member 3 is provided with an external toothed key that matches the copper sleeve 4. The end of the adjusting member 3 with the external toothed key is recessed with a threaded hole. The adjusting member 3 is connected to the handle 15 by screwing it through the copper sleeve 4.

[0032] A limiting mechanism 5 for controlling the maximum rotation angle of the adjusting member 3 is also provided between the handle 15 and the adjusting member 3. The limiting mechanism 5 includes a first limiting block 501 and a second limiting block 502 respectively fixedly installed on the installation pipe section 102 and the handle 15. By adjusting the different installation angles of the handle 15 and the adjusting member 3, the travel distance between the first limiting block 501 and the second limiting block 502 is adjusted, thereby realizing different movement distances of the adjusting member 3.

[0033] This invention features a handle 15 that can be axially detached and limited at the end of the adjusting member 3 via key teeth, facilitating control of the rotation of the adjusting member 3. A limiting mechanism 5 for controlling the maximum rotation angle is provided between the handle 15 and the adjusting member 3. By adjusting the installation angle of the handle 15, the travel distance between the first limiting block 501 on the installation pipe section 102 and the second limiting block 502 on the handle 15 is controlled, thereby limiting the rotation angle of the handle 15 and controlling the movement distance of the adjusting member 3. This, in turn, controls the maximum adjustable diameter of the feed pipe section 101, thereby limiting the maximum fuel flow rate according to different usage scenarios and improving the performance.

[0034] The main tube 1 is integrally formed with a bypass pipe 6 that connects its feed pipe section 101 and the flow pipe 2. A bypass control pipe 8 is vertically connected to the bypass pipe 6. A corresponding first adjusting screw 7 is movably and sealed inside the bypass control pipe 8. The rotation of the first adjusting screw 7 is used to control the opening and closing of the bypass pipe 6 and the adjustment of the flow rate.

[0035] The guide pipe 2 is integrally formed and connected to a main control pipe 9. A corresponding second adjusting screw 10 is movably and sealed inside the main control pipe 9. The rotation of the second adjusting screw 10 is used to control the opening and closing of the guide pipe 2 and the adjustment of the flow rate.

[0036] Traditional control valves typically have an "n"-shaped bypass channel on the inlet and outlet channels. The two ends of the bypass channel connect to the inlet and outlet channels, respectively. After the main channel is closed, fuel is supplied through the bypass channel to maintain the ignition source. However, the "n"-shaped structure of the bypass channel has multiple bends, causing resistance to fuel flow and resulting in poor flow smoothness. Therefore, this invention further incorporates an inclined connection between the L-shaped feed pipe section 101 and the guide pipe 2, forming a straight bypass pipe 6 and a first adjusting screw 7 for controlling the connection or closure of the bypass pipe 6. The straight bypass pipe 6 reduces bends, thereby lowering the pressure of fuel flow and improving its smoothness. Furthermore, the first adjusting screw 7 is perpendicular to the bypass pipe 6, ensuring the same fuel flow velocity in the bypass pipes on both sides of the first adjusting screw 7. This prevents turbulence caused by the different diameters on both sides of the first adjusting screw 7 when it is partially open, thus avoiding impeded fuel flow. The second adjusting screw 10 and the first adjusting screw 7 respectively pass through the corresponding sealing screw 12 and are connected to the corresponding main control pipe 9 and bypass pipe 6.

[0037] Each of the installation pipe section 102, the main control pipe 9, and the bypass control pipe 8 is provided with a sealing mechanism to ensure the sealing of the installation of the adjusting component 3, the second adjusting screw 10, and the first adjusting screw 7. The sealing mechanism includes a first sealing ring 11 installed in the installation pipe section 102, the main control pipe 9, or the bypass control pipe 8, and a sealing screw 12 installed at the end of the installation pipe section 102, the main control pipe 9, or the bypass control pipe 8 by means of a threaded connection. After the sealing screw 12 is installed in place, it is pressed onto the first sealing ring 11. At least one embedded annular groove is provided inwardly around the circumference of the adjusting component 3, the second adjusting screw 10, and the first adjusting screw 7, and a corresponding second sealing ring 13 is fitted in each embedded annular groove.

[0038] At least one hanging lug 14 is integrally formed on the outer side of the installation pipe section 102 of the main pipe 1. The hanging lug 14 has a corresponding threaded hole through it. The common control valve is fixedly installed by the hanging lug 14 and the screw.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
