Embodiment Construction

[0012] Such as figure 1 It is a structural schematic diagram of the present invention, a reverse gas burner regulating valve, including a valve body 1, a handle 2, a push rod 3 and a sealing cylinder 4, the handle 2 is located at the end of the valve body 1, and the sealing cylinder 4 is located at the front end of the valve body 1, The ejector rod 3 is located in the valve body 1 , and the ejector pin 5 is arranged in the sealing cylinder 4 . The thimble 5 is arrow-shaped and embedded in the sealing cylinder 4 chute. A spring 6 is provided at the end of the thimble 5 . An adjustment hole 7 corresponding to the thimble 5 is provided in the sealing cylinder 4 .

[0013] An arrow-shaped thimble 5 is arranged in the sealing cylinder 4. When the ejector rod 3 has no force on the thimble 5, the thimble 5 plugs the adjustment hole 7 under the action of the spring 6 at the tail, which has good sealing performance. Through the handle 2 Adjusting the positions of the ejector rod 3 a...

Abstract

The invention relates to the combustion apparatus technical field, and especially relates to an anti-form combustion gas combustor regulating valve comprising a valve body, a handle, a push rod and a seal cylinder; the handle is arranged in the end of the valve body; the seal cylinder is arranged in the front end of the valve body; the push rod is arranged in the valve body; a thimble is arranged in the seal cylinder in an arrow shape; when the thimble has no active force on the thimble, the thimble can fasten an adjusting hole under the effect of a tail spring, thus providing excellent sealing property; the handle can adjust positions between the push rod and the thimble so as to realize adaptation control between the thimble and the adjusting hole, thus controlling pressure; pretightening force is kept in a whole process so as to prevent loosening conditions, thus greatly improving adjusting precision and work efficiency.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a counter-type gas burner regulating valve. Background technique [0002] The gas burner is a kind of equipment that converts substances into heat energy through the chemical reaction of combustion, that is, air and gas are sent into the furnace according to the required concentration, speed, turbulence and mixing method, and the fuel can be heated in the furnace. Internally stable ignition and combustion thermal energy devices are generally used in small and medium-sized oil or gas boilers in industrial production. For existing gas burners, especially high-pressure burners, the sealing performance and adjustment accuracy of the pressure regulating device need to be improved. Contents of the invention [0003] In order to overcome the disadvantages of poor sealing and low precision of the existing gas burner regulating device, the invention provides a reverse gas ...
