Display structure for a gas valve assembly

Abstract

This invention discloses a display structure for a gas valve assembly, mainly comprising a valve body, a valve knob, and a valve control component. The valve knob is mounted at one end of an assembly identification section, with an identification section on its outer surface. The outer surface of the assembly identification section of the valve body is further surrounded by an identification area, which is further divided into at least one first area and at least one second area. When the valve knob rotates relative to the valve body and the identification section aligns with at least one first area, the valve control component activates and blocks the connection between the input end and the mounting end. Conversely, when the valve knob rotates relative to the valve body and the identification section aligns with at least one second area, the valve control component activates and opens the connection between the input end and the mounting end. By utilizing the identification section of the valve knob in conjunction with the identification area of ​​the valve body, the user can visually inspect the valve knob before rotating it to ensure the correct rotation direction. This allows the user to rotate the knob immediately without having to rely on tactile manipulation and repeatedly turning the knob, thus reducing the risk of accidents.

2. The gas valve assembly display structure as described in claim 1, wherein the identification portion of the valve button is further provided with at least one indicator bump, and the identification area is coated with pigment in a ring shape along the valve body, and the first area and the second area of ​​the identification area are distinguished by different colors of pigment, and the indicator bump moves when the valve button rotates relative to the valve body, and further points to the at least one first area or the at least one second area.

3. The gas valve assembly display structure as described in claim 2, wherein the first and second zones of the identification area each have two zones, the first zones and the second zones are arranged alternately, and there are two indicator bumps on the identification section, and the indicator bumps are arranged corresponding to each other, and each indicator bump points to the corresponding first zone or second zone when the valve button rotates relative to the valve body.

4. The gas valve assembly display structure as described in claim 1, wherein the valve control assembly further includes a front assembly, a valve plug, a positioning member, a rear assembly, a ball valve, and two valve pads located within the receiving channel. The ball valve is installed within the receiving channel and is combined with the valve button. The rotation of the valve button controls the rotation of the ball valve. The ball valve passes through a guide channel and communicates with the receiving channel and the flow channel when the valve button rotates. One of the two valve pads is installed within the receiving channel, and the other valve pad is installed in the flow channel when the connector is installed at the mounting end. The two valve pads clamp and restrict the rotation of the ball valve. Each of the two valve pads has a valve hole communicating with the receiving channel and the flow channel. The front assembly is flared and locked into the receiving channel of the valve body at one end with a first external thread. A first sleeve hole extends from one end of the front assembly to the other, connecting the valve holes of the two valve pads, the guide channel of the ball valve, and the flow channel of the connector. The rear assembly is inserted from the input end and locked into the receiving channel at one end with a second external thread. A second sleeve hole extends from one end of the rear assembly to the other, and the inner wall of the second sleeve hole has a plurality of ribs protruding towards the axis. The ends of each rib extending towards the axis of the second sleeve hole are connected to each other to form a limiting ring. The positioning member is tubular and inserted into the limiting ring at one end of the rear assembly. The outer surface of the positioning member inserted into the limiting ring has a recessed groove, while the inner wall of the limiting ring has a protruding locking block corresponding to the groove. The locking block is engaged in the groove. The valve plug further includes an umbrella-shaped plug head and a slide rod connected to one end of the plug head. A protruding block is provided on the outer surface of the plug head opposite to the end of the slide rod. The slide rod is movably inserted into the positioning member. An elastic member is provided and sleeved on the outside of the slide rod and the positioning member. When the valve plug moves telescopically relative to the positioning member, it drives the compression and release of the elastic member. When the plug head of the valve plug is deformed and blocks the first hole of the front assembly due to abnormal gas flow from the gas supply object to the pipe, the rotation of the valve button drives the rotation of the ball valve, and the ball valve pushes against the protruding block. With the pull of the elastic member, the plug head is reset.

5. The gas valve assembly display structure as described in claim 1, wherein the identification portion of the valve button is further provided with at least one viewing hole, and the identification area is coated with colorant, and the at least one viewing hole moves when the valve button rotates relative to the valve body, and further corresponds to at least one first area or at least one second area.

6. The gas valve assembly display structure as described in claim 5, wherein the first and second zones of the identification area each have two zones, each first zone and each second zone are arranged alternately, and there are also two viewing holes in the identification section, and each viewing hole is arranged corresponding to the other.
