Description

Technical Field

[0001] This utility model relates to the field of gas valve technology, and in particular to an integrated manual and electric control composite valve. Background Technology

[0002] The gas valve is the gas control device of a gas heater, directly affecting the heater's combustion performance. There are two types of existing gas control valves: one is an electrically controlled type controlled by a steady-state valve, and the other is a manually controlled type. Manually controlled gas valves are inconvenient to operate, while electrically controlled gas valves are convenient to operate and control, and are therefore widely used. Solenoid valves control the on / off of the main flame, but cannot control the gas intake of the electrically controlled valve. Existing composite valves use a split structure, enabling both electrical and manual control, but assembly is complex. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an integrated manual and electric control composite valve with a compact structure, simple assembly, and improved space utilization.

[0004] The technical solution of this utility model is as follows: an integrated manual and electric control composite valve, including a steady-state valve and a manual control valve. The steady-state valve and the manual control valve are integrally connected. The steady-state valve is provided with a valve cavity, and a control component is provided above the valve cavity. The steady-state valve is provided with an outlet pipe at one end of the valve cavity, and the other end is connected to the manual control valve. The outlet pipe is horizontally connected to the valve cavity. The manual control valve includes a valve body, a valve cover connected to the end of the valve body, a valve core disposed in the valve body, and a valve stem rotatably connected in the valve body. One end of the valve stem extends into the valve core, and the other end extends out of the valve cover. A gas inlet seat is provided on the valve body, and the gas inlet seat is disposed at the bottom of the valve body. The valve body is connected to the valve cavity through a gas outlet.

[0005] Therefore, the steady-state valve is used to control the opening and closing of the gas path in the valve body by switching the power on and off. The valve stem is used to drive the valve core to rotate by feeding rotation, thereby adjusting the firepower. The gas inlet seat is used to connect to the gas source to realize the gas intake. After the gas flows through the valve core, it enters the valve cavity and then flows out from the gas outlet pipe to realize the gas exhaust. This utility model adopts an integrated structure, which is compact, easy to assemble, and improves the space utilization rate.

[0006] The valve core has a rotating cavity at one end and an outlet cavity at the other end. The rotating cavity is adapted to the end of the valve stem, and the outlet cavity communicates with the gas outlet. The valve core has an inlet flame hole that corresponds to the outlet cavity, and the inlet flame hole is connected to a linear flame groove on the valve core. The width of the linear flame groove gradually decreases in the direction away from the inlet flame hole. Therefore, when the valve core rotates until the inlet flame hole aligns with the gas inlet seat, gas is introduced. The linear flame groove is used to linearly adjust the gas intake, thereby regulating the flame intensity.

[0007] A locating pin that is linked to the valve core is inserted into the valve stem. A locating hole adapted to the locating pin is provided at the end of the valve stem, and a movable groove adapted to the locating pin is provided at the end of the valve core. Therefore, the locating pin is used to drive the valve core to rotate after being inserted into the locating hole, and the movable groove is used to lock the locating pin in place after it rotates.

[0008] The control component includes a stationary iron core, a moving iron core, a coil module, and a spring. The spring is sleeved on the moving iron core, and a plug is provided at the bottom of the moving iron core. One end of the spring is connected to the bottom of the valve cavity, and the other end is connected to the plug. Therefore, the coil module is used to energize and drive the moving iron core to move upwards to attract the stationary iron core.

[0009] The moving iron core is provided with a locking groove, and the plug is provided with a locking protrusion that matches the locking groove. Therefore, the plug achieves a detachable connection between the plug and the moving iron core by matching the locking protrusion with the locking groove on the moving iron core.

[0010] A mounting plate is fitted onto the valve cover, and bent pieces are connected to both sides of the mounting plate. Each bent piece has a mounting through hole. Therefore, the bent pieces are positioned and installed through these mounting through holes. Attached Figure Description

The gas inlet seat 41 is provided at the bottom of the valve body 4. The valve body 4 is connected to the valve cavity 10 through a gas outlet.

[0017] In this embodiment, a control board is externally connected to the steady-state valve to regulate the gas flow. A sensor electrically connected to the steady-state valve is installed at the burner head. If the sensor detects insufficient flame temperature, the steady-state valve automatically closes, achieving intelligent regulation. Figure 1 As shown, the manual control valve 2 is inclinedly mounted on the steady-state valve 1, with an angle of 60 degrees between the manual control valve 2 and the steady-state valve 1, and a horizontal angle of 30 degrees between the manual control valve 2 and the steady-state valve 1. In another embodiment, as shown... Figure 4 As shown, the manual control valve 2 is vertically positioned relative to the steady-state valve 1, and the horizontal angle between the manual control valve 2 and the steady-state valve 1 is 0 degrees.

[0018] The control component includes a stationary iron core 31, a moving iron core 32, a coil module 33, and a spring 34. The spring 34 is sleeved on the moving iron core 32. A plug 35 is provided at the bottom of the moving iron core 32. One end of the spring 34 is connected to the bottom of the valve cavity 10, and the other end is connected to the plug 35. A locking groove 321 is provided on the moving iron core 32, and a locking protrusion 351 adapted to the locking groove 321 is provided on the plug 35.

[0019] The valve core 6 has a rotating cavity 61 at one end and an outlet cavity 62 at the other end. The rotating cavity 61 is adapted to the end of the valve stem 7. The outlet cavity 62 communicates with the gas outlet. The valve core 6 has an inlet flame hole 63 connected to the outlet cavity 62. The inlet flame hole 63 communicates with a linear flame groove 64 on the valve core 6. The width of the linear flame groove 64 gradually decreases in the direction away from the inlet flame hole 63. In this embodiment, the valve core 6 also has a permanent flame hole.

[0020] The valve stem 7 is provided with a positioning pin that is linked to the valve core 6. The valve stem 7 has a positioning hole 71 that matches the positioning pin at its end. The valve core 6 has a movable groove 65 that matches the positioning pin at its end.

[0021] The valve cover 5 is fitted with a fixing plate 51, and the two sides of the fixing plate 51 are connected with bending plates 14, and the bending plates 14 are provided with mounting through holes 141.

[0022] The working process of this utility model is as follows: When the gas supply is controlled by the steady-state valve 1, the coil module is energized to generate a magnetic field. The moving iron core 32 moves upward and attracts the stationary iron core 31. The moving iron core 32 drives the plug 35 to move upward. At this time, the spring 34 is compressed, the steady-state valve 1 opens, and the gas path between the steady-state valve 1 and the manual control valve 2 is connected. Gas is discharged from the gas outlet pipe 11, the coil module is de-energized, the stationary iron core 31 stops attracting the moving iron core 32, and the spring 34 resets and drives the plug 35 to move downward into the valve cavity. The valve cuts off the gas source by blocking the gas path within 10. When manually controlling the valve, rotate the valve stem 7, which drives the valve core 6 to rotate to the corresponding fire hole position through the positioning pin. The positioning pin fixes the valve core in position through the movable groove 65. Release the hand holding the valve stem 7, and the gas source enters from the gas inlet seat 41. The gas path in the valve body 4 is opened, and the gas flows from the valve core 6 through the gas outlet to the valve cavity 10. The gas path is opened by controlling the steady-state valve 1, and the gas is discharged from the gas outlet pipe 11 to the stove for ignition and combustion.
