The gas valve that described a kind of family expenses kitchen range are used, its special way is: there is the radially-directed piece at the middle part that described arc is rolled over the edge outward, and the top end of radially-directed piece and spool chamber is slidingly matched.

The gas valve that described a kind of family expenses kitchen range are used, its special way is: described valve seat comprises that the lid of fixed base, under shed and the valve rod that is arranged on the lid stretch out the hole;

A guide table and two stop bit platforms of the oriented lid convex of the top of described lid, the gap between guide table and the individual stop bit platform constitutes the stop bit locating slot;

The stop bit platform the axial end and the top end of spool chamber fit the gap formation guiding groove between the top end of guide table and spool chamber;

Radially-directed piece and guiding groove are slidingly matched, and radially-directed piece and stop bit locating slot are chimeric, and the radially-directed piece cooperates stop bit with an end of stop bit platform.

The gas valve that a kind of family expenses kitchen range of the utility model are used, owing to adopt such structure, valve seat is made by metal plate punching, compares with the available technology adopting extrusion process, and power consumption is few, and any surface finish, and cost is low.Valve rod adopts tubing to make, and compares with available technology adopting round iron, copper, aluminium, and technology is simple, and cost is low.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As Fig. 1, Fig. 2, shown in Figure 3, the gas valve that a kind of family expenses kitchen range are used, comprise valve body 1, spool 2, valve seat 3, valve rod 4 and valve core spring 5, described valve body 1 have up/down perforation spool chamber 11 and with the perpendicular gas-entered passageway 12 of spool chamber 11, valve core spring 5 is arranged between spool 2 tops and valve rod 4 lower ends, valve seat 3 is arranged on the top of spool chamber 11, and stretch out from valve seat 3 valve rod 4 upper ends; Described valve seat 3 is made by panel beating sheet material is one-body molded, has valve rod to stretch out hole 31 on the valve seat 3; Valve rod 4 stretches out hole 31 with valve rod and is rotatably assorted.

The top of described spool 2 has falls level 21, and falling on the spool on level 21 tops has vertically locating slot 22;

Described valve rod 4 is made by tubing, bottom one side of described valve rod 4 have the outer folding of arc along 41, opposite side has locating stud 42 vertically; The outer folding of described valve core spring 5 upper ends and arc along 41 cooperate, the lower end with fall level 21 and cooperate, locating stud 42 is positioned at valve core spring 5, locating stud 42 cooperates with locating slot 22, arc is rolled over outward along 41 and the top end of the spool chamber 11 also stop bit that is slidingly matched.
