Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] like Figure 1-14 Shown is a preferred embodiment of the present invention.

[0035]A gas cock valve with a gapless knob structure includes a valve casing 1 and a valve stem 2, and the valve stem 2 is provided with a knob assembly. The knob assembly includes a knob housing 3, a support spring 4 and a knob core 5. The upper end surface of the knob housing 3 has a recess 31 for accommodating the knob core 5, and the lower end surface of the knob core 5 has a rod 51 extending downward. The rod part 51 passes through the bottom of the concave part 31 and is set on the upper part of the valve stem 2. The rotation of the knob shell 3 can drive the rotation of the knob core 5, and the rotation of the knob core 5 can drive the rotation of the valve stem 2. At the same time, the knob core 5 can rotate relative to the knob. The shell 3 moves up...

Abstract

The invention relates to a gas plug valve with a gap-free rotary knob structure. The gas plug valve comprises a valve casing, a valve rod and a rotary knob assembly and is characterized in that the rotary knob assembly comprises a rotary knob casing, a supporting spring and a rotary knob core, the rotary knob casing is provided with the concave portion for accommodating the rotary knob core, and the lower end face of the rotary knob core is provided with the rod portion extending downward. The rod portion of the rotary knob core penetrates the bottom of the concave portion and sleeves the upper portion of a valve rod, the rotary knob core can be driven to rotate by the rotary knob casing in rotation, the rotary knob core can drive the valve rod to rotate through rotation and meanwhile can vertically move relative to the rotary knob casing and drive the valve rod to vertically move through vertical movement, and the supporting spring sleeves the rod portion of the rotary knob core and is supported between the bottom of the concave portion and the lower end face of the rotary knob core. The rotary knob core still has a downward movement function of an original rotary knob, the rotary knob casing acts with the rotary knob core through the supporting spring and can always adhere to a panel of a gas stove under the spring force effect to achieve gap-free matching between the rotary knob and the panel.

Description

technical field [0001] The invention relates to a gas cock valve used on a gas cooker, in particular to a gas cock valve with a gapless knob structure. Background technique [0002] The gas cock valve used for gas appliances generally includes a valve body with an air inlet channel and an air outlet channel, a valve core with a large fire hole and a small fire hole in the valve body, and a valve stem connected to the valve core. stem. The top of the valve stem will be connected with the knob installed on the cooker panel. When in use, the knob can be operated to control the knob rod. Generally, the knob should be pressed first and turned counterclockwise to drive the valve core to rotate counterclockwise to make the fire on the valve core The hole communicates with the air inlet channel in the valve body, and the gas source can be sprayed out from the nozzle through the air inlet channel and the air outlet channel for use by gas appliances. [0003] There is a gap greater ...
