Detailed Description

The technical solution of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention.

Referring to fig. 1 to 4, the present invention relates to a natural gas valve protection mechanism, which includes a natural gas valve 1 having an operating handle 11. The natural gas valve 1 is a conventional natural gas valve. The natural gas valve 1 can be opened and closed by operating the operating handle 11, for example, by rotating the operating handle 11.

The natural gas valve protection mechanism also comprises a protection cover 2 and a fastener 3; the protective cover 2 is fixedly connected with the natural gas valve 1 through a fastener 3.

The protective cover 2 comprises a top cover 21, a cover side wall 22, a hinged wall 23 and a fixing part 24, wherein the top cover 21, the cover side wall 22 and the hinged wall 23 are fixedly connected in sequence, and the hinged wall 23 is hinged with the fixing part 24 and keeps a relative position. The hinge wall 23 and the fixing portion 24 can be hinged by conventional means such as a hinge (not shown in the drawings), and the hinge wall 23 and the fixing portion 24 are held in a relative position by means of a damping force of the hinge itself.

The working principle is as follows: at ordinary times, the protection cover 2 is in a protection state, and hands and the like cannot pass through the top cover 21 and the cover side wall 22 to touch the operation handle 11, so that the natural gas valve 1 is protected.

When the operating handle 11 needs to be operated, the top cover 21 or the cover side wall 22 is pulled, so that the top cover 21 and the cover side wall 22 rotate around the hinge axis 239 until the operating handle 11 is exposed and a human hand can pass through the position of the top cover 21 in a protection state, touch the operating handle 11, and operate the operating handle 11.

After the operation handle 11 is operated, the top cover 21 or the cover side wall 22 is moved and pulled, so that the protective cover 2 is reset to a protective state, and the natural gas valve 1 is protected.

Can find out by the aforesaid, the utility model discloses a natural gas valve protection machanism, when can be to the operation handle 11 protection of natural gas valve 1, be convenient for open back operation handle 11.

The hinge wall 23 and the fixing portion 24 are integrated, and the hinge wall 23 and the fixing portion 24 have elasticity. The shield 2 is usually a stainless steel plate, which is punched and cut, and then bent, so that the hinge wall 23 and the fixing portion 24 have elasticity. After the operation handle 11 is operated, the protection cover 2 can be automatically reset, and the operation is more convenient.

The hinge axis of the hinge wall 23 and the fixing portion 24 is a hinge axis 239, and the fixing portion 24 is recessed along the hinge axis 239 (not shown in the drawings). Typically, the recesses are triangular in cross-section. When the top cover 21 or the cover side wall 22 is pulled, the stress applied to the hinge axis 239 is small, so that the hinge wall 23 can rotate around the hinge axis 239, the rotation tracks of the top cover 21 and the cover side wall 22 are in accordance with the expectation, and the operating handle 11 cannot be touched.

The fixing portion 24 is fixedly provided with a limiting wall 242, and the other end of the limiting wall 242 abuts against the hinge wall 23. The position of the hinge wall 23 can be defined to prevent the protective state cover side wall 22 from touching the operating handle 11. The other end of the limit wall 242 is fixedly provided with a limit abutting body 243 attached to the hinge wall 23. The contact area of the other end of the stopper wall 242 with the hinge wall 23 can be increased, so that the effect of restricting the position of the hinge wall 23 can be ensured. The stopper wall 242 has elasticity. After the operation handle 11 is operated, when the shield 2 is automatically returned, the limit wall 242 can buffer the shield, so that noise generated when the hinge wall 23 collides with the hinge wall 23 when the shield 2 is automatically returned can be reduced.

The natural gas valve 1 is provided with a valve outer edge 12, the fixing portion 24 is fixedly provided with a fixing ring 241, the fastener 3 is a hoop, and the valve outer edge 12, the fixing ring 241 and the fastener 3 are sequentially arranged from inside to outside. The shield 2 is usually made of a stainless steel plate, which is punched and cut, and then bent so that a notch (not shown) is formed in the fixing ring 241 and the fixing ring 241 is not sealed. The protective cover 2 is convenient to be fixed on the natural gas valve 1.

The hood 2 is made as an integral sheet (not shown in the drawings). The shield 2 is usually made of a stainless steel plate, which is punched and cut, and then bent. The production process of the protective cover 2 is simple and is beneficial to reducing the cost.

It will be understood that the terms "central," "longitudinal," "lateral," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for the convenience and simplicity of description, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered limiting of the scope of the present invention.
