Description

Technical Field

[0001] The utility model belongs to a component of commercial kitchenware, in particular to an energy-saving commercial kitchenware air valve with high air volume adjustment accuracy. Background Art

[0002] The main function of the air damper of commercial kitchen appliances (such as gas stoves) is to adjust the fire power and control the flame color.

[0003] Traditional dampers for commercial kitchen appliances generally include a valve body, a valve plate, and a valve plate adjustment assembly. The valve plate adjustment assembly is used to adjust the angle of the valve plate inside the valve body to adjust the air volume and air pressure. Since commercial kitchen appliances often have high firepower, a large opening and closing structure will not cause problems when the firepower is high; however, this structure makes it difficult to control the air volume, air pressure, and firepower accurately when a low fire is required, and usually the adjustment fails and causes the flameout. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide an energy-saving commercial kitchen air valve that adopts a pressure relief hole in conjunction with a main valve plate to accurately adjust the air volume, air pressure and fire power, and the opening and closing adjustment of the pressure relief hole and the angle adjustment of the main valve plate are carried out synchronously, that is, a linkage structure of the pressure relief hole mask and the main valve plate is adopted, and the angle of the main valve plate and the opening and closing size of the pressure relief hole can be adjusted together by simply rotating the main adjustment shaft. The adjustment is very simple and convenient, the adjustment accuracy is very high, and it can ensure that both high and low fires are very stable and reliable and the air volume adjustment accuracy is high.

[0005] The technical solution of the utility model is as follows: An energy-saving commercial kitchen air valve with high air volume adjustment accuracy, comprising a valve body, an air inlet arranged at one end of the valve body, an air outlet arranged at the other end of the valve body, a main valve plate arranged on the inner side of the valve body, a pressure relief hole arranged on the valve body, and a main adjustment component for adjusting the angle of the main valve plate, the pressure relief hole being located between the main valve plate and the air inlet near the main valve plate, the main adjustment component comprising a main adjustment shaft fixed on the main valve plate, a pressure relief hole mask plate fixed at both ends of the main adjustment shaft, and an adjustment handle connected to one end of the main adjustment shaft, the main adjustment shaft being rotatably connected to the valve body, a pressure relief adjustment hole matching the pressure relief hole being provided on the pressure relief hole mask plate, the adjustment handle being located on the outer side of the valve body, and a compensation port being further connected to the valve body, the compensation port being located between the pressure relief hole and the air inlet near the air inlet.

[0006] The utility model adopts the pressure relief hole to cooperate with the main valve plate to accurately adjust the air volume, air pressure and firepower, and the opening and closing adjustment of the pressure relief hole and the angle adjustment of the main valve plate are carried out synchronously, that is, the linkage structure of the pressure relief hole mask and the main valve plate is adopted. Only the main adjustment shaft needs to be rotated to adjust the angle of the main valve plate and the opening and closing size of the pressure relief hole. The adjustment is very simple and convenient, and the adjustment accuracy is very high, which can ensure that both high and low fires are very stable and reliable.

[0007] Preferably, pressure relief holes are provided on two opposite side surfaces of the valve body, the two pressure relief hole masks correspond to the two pressure relief holes respectively, and the compensation port is located on the other side surface of the valve body and is staggered from the side surface where the pressure relief holes are located.

[0008] This structure ensures the pressure relief effect of wind pressure and the compensation effect of air volume.

[0009] Preferably, the pressure relief hole mask is circular, the main adjustment shaft is fixed to the center of the pressure relief hole mask, and one side surface of the pressure relief hole mask is connected to the main valve plate.

[0011] Preferably, a pressure-regulating valve plate is provided inside the valve body, and the pressure-regulating valve plate is located between the main valve plate and the air outlet, close to the air outlet. The valve body is provided with a sub-adjusting component for adjusting the angle of the pressure-regulating valve plate, and the sub-adjusting component includes a sub-adjusting shaft fixed on the pressure-regulating valve plate, an adjusting positioning plate cooperating with the sub-adjusting shaft, and an adjusting positioning bolt cooperating with the adjusting positioning plate. The sub-adjusting shaft is rotatably connected to the valve body, and the adjusting positioning plate and the adjusting positioning bolt are located on the outside of the valve body.

[0012] This structure can adjust the angle of the pressure regulating valve plate in the valve body by manually rotating the adjustment positioning piece, and further adjust the wind pressure to ensure the stability and reliability of the wind pressure.

When the main adjustment shaft is adjusted to a certain position, the positions of the main valve plate and the pressure relief hole mask are determined. However, since in actual use, the wind pressure, air volume and firepower are affected by various factors (such as the external environment and the chef's operation, etc.), it is sometimes necessary to manually fine-tune the opening and closing size of the pressure relief hole.

[0017] Preferably, a main valve plate groove matching the main valve plate is provided in the middle of the main adjusting shaft, and the main valve plate is installed in the main valve plate groove and fixed by the main valve plate screws. A secondary valve plate groove matching the pressure regulating valve plate is provided in the middle of the secondary adjusting shaft, and the pressure regulating valve plate is installed in the secondary valve plate groove and fixed by the secondary valve plate screws.

[0018] This structure ensures that the connection between the main valve plate and the main regulating shaft, and between the pressure regulating valve plate and the auxiliary regulating shaft is firm and reliable, ensuring that the rotation of the main valve plate and the pressure regulating valve plate is more stable and reliable.

[0020] This structure ensures that the connection between the adjusting handle and the main adjusting shaft is stable, thereby ensuring that the rotation of the main adjusting shaft driven by rotating the adjusting handle is smoother and more reliable.

[0021] Preferably, the air inlet is connected to an air inlet joint, the air outlet is connected to an air outlet joint, the compensation port is connected to a compensation joint, and the compensation joint is arranged at an angle.

[0022] This structure facilitates the connection between the valve body and the pipeline, ensuring stable and reliable air inlet and outlet as well as compensation air volume.

[0025] The utility model adopts the pressure relief hole to cooperate with the main valve plate to accurately adjust the air volume, air pressure and firepower, and the opening and closing adjustment of the pressure relief hole and the angle adjustment of the main valve plate are carried out synchronously, that is, the linkage structure of the pressure relief hole mask and the main valve plate is adopted. Only the main adjustment shaft needs to be rotated to adjust the angle of the main valve plate and the opening and closing size of the pressure relief hole. The adjustment is very simple and convenient, and the adjustment accuracy is very high, which can ensure that both high and low fires are very stable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
