Description

Technical Field

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

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

[0003] Traditional commercial kitchen air valves 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 accuracy of air volume, air pressure and firepower when a low fire is required, and usually the adjustment fails, resulting in flameout. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a method for accurately adjusting the air volume, air pressure and fire power by using a pressure relief hole in cooperation with a main valve plate, wherein the opening and closing adjustment of the pressure relief hole and the angle adjustment of the main valve plate are performed simultaneously, that is, a linkage structure of the pressure relief hole mask plate 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 only by rotating the main adjustment shaft. 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, and an energy-saving commercial kitchen air valve with high air volume adjustment accuracy can be used.

[0005] The technical solution of the present invention is as follows: An energy-saving commercial kitchen air valve with high air volume adjustment accuracy comprises 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 at 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, wherein the pressure relief hole is located between the main valve plate and the air inlet near the main valve plate, the main adjustment component comprises 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 is rotatably connected to the valve body, a pressure relief adjustment hole matching the pressure relief hole is provided on the pressure relief hole mask plate, the adjustment handle is located on the outer side of the valve body, and a compensation port is also connected to the valve body, and the compensation port is located between the pressure relief hole and the air inlet near the air inlet.

[0006] The present invention 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 plate 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 only by rotating the main adjusting shaft. The adjustment is very simple and convenient, and the adjustment accuracy is very high, which can ensure that both large and small fires are very stable and reliable.

[0007] Preferably, pressure relief holes are provided on two opposite side surfaces of the valve body, 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; a sub-adjusting component for adjusting the angle of the pressure regulating valve plate is provided on the valve body, 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 adjusting positioning piece, and further adjust the wind pressure to ensure the stability and reliability of the wind pressure.

[0013] Preferably, the adjusting positioning piece is provided with an arc-shaped limiting hole for limiting the adjusting angle of the auxiliary adjusting shaft, and the adjusting positioning bolt is located at the arc-shaped limiting hole to fix or loosen the adjusting positioning piece.

[0014] This structure ensures that the restriction on the rotation angle of the regulating valve plate is more stable and reliable, thereby further ensuring the stability and reliability of the wind pressure regulation.

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, in actual use, the wind pressure, air volume and firepower are affected by various factors (such as external environment and chef operation, etc.), and sometimes it is necessary to manually fine-tune the opening and closing size of the pressure relief hole.

[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, and ensures that the rotation of the main valve plate and the pressure regulating valve plate is more stable and reliable.

[0019] Preferably, one end of the main adjusting shaft extends out of the valve body, and the adjusting handle is sleeved on the extended section of the main adjusting shaft and is locked by a locking bolt.

[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 obliquely.

[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.

[0024] This structure makes the valve beautiful and elegant in appearance, and the square valve body is convenient for installation on kitchen utensils.

[0025] The present invention 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 plate 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 only by rotating the main adjusting shaft. The adjustment is very simple and convenient, and the adjustment accuracy is very high, which can ensure that both large and small fires are very stable and reliable.
