Problems solved by technology

In the existing plug valve, when the valve stem is adjusting the size of the fire, the rotation of the valve stem is not damped, and the valve stem can be easily driven to rotate, and the handle is poor. In the event of a fire, it is difficult to accurately control the size of the fire

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0017] Such as Figure 1-3 As shown, the gas cock valve of the present invention includes a valve body 1, a valve core 2 and a valve stem 3. The end of the valve body 1 is fixedly provided with a valve cover 5, the valve core 2 is arranged in the valve body 1, and the valve stem 3 One end passes through the valve cover 5 and is connected to the end of the valve core 2 and is arranged coaxially with the valve core 2 to drive the valve core 2 to rotate. The valve body 1 also includes a spring 4 sleeved on the end of the valve core 2 and one end of the valve stem 3 outside, and one end of the spring 4 abuts against the valve core 2 and one end against the valve stem 3, so that One end of the valve stem 3 has a tendency to always be away from the valve core 2 and the end of the valve core 2 is disconnected from the valve core 2, that is, the valve stem 3 has ...

Abstract

A gas plug valve comprises a valve body, a valve element and a valve rod; the valve element is located in the valve body, a valve cover is fixed to the end of the valve body, the outer side of the valve element or valve rod is further sleeved with a damping mechanism, and the damping mechanism comprises a first friction part and a second friction part; one of the first friction part and the second friction part and the valve body or valve cover are fixed, and the other one of the first friction part and the second friction part is fixed circumferentially relative to the valve rod or valve element and is movable axially relative to the valve rod or valve element; and the first friction part and the second friction part have the tendency of tight attaching all the time, tooth-shaped concave and convex parts which are distributed in the circumferential direction of the second friction part are arranged on the face, opposite to the first friction part, of the second friction part, and protruding blocks which protrude towards the tooth-shaped concave and convex parts and are matched with the tooth-shaped concave and convex parts are arranged on the face, opposite to the second friction part, of the first friction part. The gas plug valve is simple and compact in structure, when the valve rod rotates, the valve rod has the damping friction feeling and is good in hand feeling and accurate in rotary positioning no matter whether the valve rod is pressed down relative to the valve element or not.

Description

Technical field [0001] The invention relates to a gas cock valve. Background technique [0002] The plug valve in the gas cooker is a manually operated valve that controls the gas supply. Ordinary plug valves generally include a valve body with an air inlet channel and an air outlet channel. The valve body is provided with a rotatable valve core. The upper part of the valve core has a spring cavity, and the lower part of the valve core is provided with a venting cavity. The valve stem is rotated by the valve core. The lower end of the valve stem holds a spring that keeps the valve stem moving upward and away from the connection trend with the valve core. The spring is located in the spring cavity on the valve core, and the side wall of the vent cavity of the valve core is opened. To connect the large fire hole and the small fire hole of the air inlet channel and the air outlet channel. When in use, the user operates the valve stem through the knob set on the operation panel. Ge...
