2results about How to "Increase the tilt angle" patented technology

The utility model relates to a kind of gas stove head, including fire seat and first injection pipe, first gas cavity is equipped in fire seat, first gas cavity forms lower gas layer and upper gas layer along by lower to upper distribution, the position of fire seat corresponding lower gas layer is connected with first injection pipe, first injection pipe is communicated with first gas cavity by lower gas layer, lower gas layer and upper gas layer between are equipped with the flow guide surface for guiding airflow from lower gas layer into upper gas layer, the included angle a between flow guide surface and horizontal plane is formed, 85°≤a≤90°, by optimizing the structure of flow guide surface, relative increase the inclination angle between flow guide surface and horizontal plane, mixed gas is diffused in first gas cavity at relatively slow speed under the action of flow guide surface, it is favorable to make mixed gas more fully mixed, to improve the combustion heat efficiency of equipment, reduce the carbon monoxide content generated by combustion.

This invention relates to the field of steel plate welding technology, specifically to a steel plate butt welding device, including a base and a processing table, as well as a welding mechanism, a heating mechanism, a beveling mechanism, and a splicing mechanism. The splicing mechanism includes a drive assembly, two feeding plates, and two clamping assemblies. The beveling mechanism includes a bidirectional electric push rod, a position adjustment assembly, two grinding discs, and two swinging assemblies. A support column is fixedly provided on the top of the base. The heating mechanism includes a telescopic assembly, a first sliding assembly, and four electric heating plates. The welding mechanism includes a welding torch, a second sliding assembly, and two traction assemblies. This steel plate butt welding device of the present invention prevents visual errors caused by manual beveling based solely on experience, improves the adjustment accuracy of the grinding disc tilt angle, further improves the beveling accuracy, ensures the uniformity of the beveling of the two steel plates, and prevents problems such as incomplete penetration, welding deformation, and undercut, thereby improving the butt welding effect of the two steel plates.
