Embodiment Construction
[0006] Referring to the accompanying drawings, a method for maintaining the verticality of the transmission shaft in a gas valve mainly includes the following steps, a. providing a positioning plate, the positioning plate is a plate body 10; b. providing a screw thread on the plate body 10 The shaft hole 20 closely matched with the transmission shaft, the center line of the shaft hole 20 is perpendicular to the bottom of the main magnetic steel displacement cavity. Therefore, after the threaded transmission shaft is inserted, it is difficult to swing in the vertical direction, which ensures the stability of its work.

The present invention discloses a method for retaining perpendicularity of drive shaft in gas valve. Said method includes the following steps: a), providing a positioning plate, said positioning plate is a plate body; and b), on the plate body providing a shaft hole which can be fitted tightly against the screw drive shaft, said shaft hole is perpendicular to the main magnetic steel displacement cavity body bottom portion.
Description
Technical field: [0001] The invention relates to a manufacturing technology of a valve, in particular to a positioning method of a screw drive shaft in a gas valve. Background technique: [0002] When the threaded transmission shaft in the gas safety valve is working, it is easy to swing in the vertical direction, which affects its working stability. At present, most of the solutions seen are complex in structure, but the effect is not satisfactory. Invention content: [0003] The object of the present invention is to provide a method that can effectively overcome the above defects and maintain the verticality of the transmission shaft in the gas valve. The technical solution adopted by the present invention to solve the above-mentioned problems is a method for maintaining the verticality of the transmission shaft in a gas valve, which is characterized in that it mainly includes the following steps, a. providing a positioning plate, and the positioning plate is a plate bo...
