description of reference numerals: the gas valve comprises a hand lever 1, an outer lever 2, an inner lever 3, a ratchet groove cover 4, a fixing screw 5, a blow-off valve switch sleeve 6, a gas valve switch sleeve 7, a ratchet 8, a slide block 9 and a spring 10.

Detailed Description

The present invention will be further described with reference to the following examples. The following description of the embodiments is merely provided to aid in understanding the invention. It should be noted that, for those skilled in the art, the present invention can be modified in several ways without departing from the principle of the present invention, and these modifications and modifications also fall into the protection scope of the claims of the present invention.

Example 1:

as shown in fig. 1, the key for the gas valve and the bleeding valve of the gas valve well comprises a hand lever 1, an outer lever 2, an inner lever 3, a ratchet groove cover 4, a fixing screw 5, a bleeding valve switch sleeve 6 and a gas valve switch sleeve 7;

wherein, the hand lever 1 is transversely arranged and is connected with the end part of the outer lever 2 which is longitudinally arranged; the outer rod 2 is connected with the inner rod 3 through a fixing screw 5; the outer rod 2 is provided with an inner groove; the inner rod 3 is sleeved in the inner groove of the outer rod 2; the outer rod 2, the inner rod 3 and the fixing screw 5 form a telescopic rod with adjustable length; the ratchet groove cover 4 is arranged on the inner rod 3; as shown in fig. 2, a ratchet 8, a slider 9 and a spring 10 are arranged inside the ratchet groove cover 4; as shown in fig. 3, the inner rod 3 is provided with an inner groove, and the slide block 9 and the spring 10 are embedded into the inner groove of the inner rod 3; one end of the sliding block 2, which is far away from the spring 10, is attached to the gear of the ratchet wheel 8; two sides of the ratchet wheel groove cover 4 are provided with the bleeding valve opening and closing sleeves 6, and the bleeding valve opening and closing sleeves 6 at the two sides are symmetrical; the blow-off valve switch sleeve 6 is provided with a groove; the gas valve switch sleeve 7 is connected with one end of the inner rod 3 far away from the fixing screw; the gas valve switch sleeve 7 is provided with a groove.

The utility model discloses a theory of operation does:

as shown in fig. 1, an inner rod 3 can be sleeved into an outer rod 2 with an inner groove, and a fixing screw 5 is combined to realize the length adjustment function of the operating rod; the inside ratchet of ratchet capping 4 can realize the one-way rotation of diffusion valve switch cover 6, diffusion valve switch cover 6 can overlap on the diffusion valve switch, when self pivoted, drive the diffusion valve and rotate, the inside groove that opens of gas valve switch cover 7, can overlap and drive the valve switch rotation on the gas valve switch, therefore, when 7 covers on the gas valve switch of gas valve switch cover, rotate gas valve switch cover 7 through handle bar 1, can realize the switching of gas valve, when 6 covers on the diffusion valve switch of diffusion valve switch cover, through rotating handle bar 1, can realize the switching of diffusion valve.

As shown in fig. 2, when the slider 9 rotates counterclockwise, the slider 9 reciprocates along the axial direction of the spring 10 due to the reaction force given to the slider 9 by the ratchet 8, the slider 9 and the ratchet 8 move relatively, and when the slider 9 moves clockwise, the ratchet 8 cannot give a component force to the slider 9 in the axial direction of the spring 10, so that when the slider 9 moves clockwise, the ratchet 8 is driven to move clockwise synchronously.

As shown in fig. 3, the slider 9 and the spring 10 are embedded in the inner groove of the inner rod 3, the elasticity of the spring 10 enables the slider 9 to be always attached to the gear of the ratchet 8, the rotation of the inner rod 3 can drive the slider 9 and the spring 10 to rotate along the axial direction of the ratchet 8, the rotation of the slider 9 can drive the ratchet 8 to rotate or the slider 9 slides on the gear of the ratchet 8 according to different rotation directions, but the ratchet 8 does not rotate.
