Embodiment Construction

[0027] Such as Figure 2-4 As shown, a gas cock valve includes a valve body 1, a valve stem 2, a valve core 3 and a thimble 5 passing through the valve core 3. The valve body 1 has a valve core hole for assembling the valve core 3 (for simplified structure, image 3 with Figure 4 The valve body part is omitted, so the spool hole is not shown) and the cover plate 10 sealing the spool hole. The valve stem 2 extends to the position of the valve core 3 through the cover plate 10 and is connected with the thimble 5 .

[0028] Such as figure 2 As shown, the valve body 1 is provided with an air inlet 13, an inner ring air outlet 11 and an outer ring air outlet 12, and the inner ring air outlet 11, the outer ring air outlet 12 meet the side wall of the valve core hole to form an inner ring air intake mouth and outer ring air inlet (not shown in the figure). When the air inlet of the inner ring and the air inlet of the outer ring are aligned with the gas distribution hole on the ...

Abstract

The invention discloses a fuel gas cock valve. The fuel gas cock valve comprises a valve body, a valve element, a valve rod and an ejector pin penetrating through the valve element, the valve body isprovided with a valve core hole for assembling the valve element and a cover plate for sealing the valve core hole, one end of the valve rod penetrates through the cover plate, a shifting fork is arranged on the side face of the end of the valve rod, a limiting groove matched with the shifting fork to limit rotation of the valve rod is arranged on the back face of the cover plate, the valve rod isof a sectional structure comprising a main rod and a shifting wheel which are linked, the shifting fork is arranged on the side face of the shifting wheel, the main rod and the shifting wheel are provided with a first end surface and a second end surface which are in contact in the process of pressing the valve rod respectively, a first spring which is in abutting connection with the shifting wheel and can drive the shifting wheel to be reset is arranged below the shifting wheel, the ejector pin penetrates through the shifting wheel and is connected with the main rod, and a gap is formed between the first end surface and the second end surface before the cock valve is opened. According to the fuel gas cock valve, the stroke of the pressing of the valve rod is increased, an electromagneticvalve can be opened by the ejector pin, and the ignition failure is avoided.

Description

technical field [0001] The invention relates to a gas cock valve, in particular to a gas cock valve capable of ensuring successful ignition. Background technique [0002] The gas cock valve is installed on the cooker and is used to control the firepower of the cooker. Such as figure 1 As shown, the gas cock valve includes a valve body 1, a valve stem 2 and a valve core 3, wherein the valve body 1 is provided with an arched bracket 41 for fixing the valve stem 2, the cross section of the valve stem 2 is a D-shaped structure, and the outside is sheathed There are parts such as jump ring 42, limit plate 43 and pressure plate 44, and limit plate 43 is provided with the through hole that matches with valve stem 2 and limit hole, has the limit hole that matches with limit hole on the arch support 4. bit raised 40. [0003] In the closed state of the cock valve, the limiting protrusion 40 is inserted into the limiting hole to prevent the rotation of the valve stem. When the plu...
