Description

Valve body structure with switch display function TECHNICAL FIELD

[0001] The valve body structure with switch display function of the present application is mainly applied to the field of gas and can help users quickly identify the on-off state of the valve to prevent dangerous situations caused by incorrect rotation. BACKGROUND

[0002] In today's homes, the common use of gas is gas cylinders and natural gas. Such energy sources are highly dangerous, so they must be controlled by on-off devices to allow gas to pass. In fact, not only gas, but also water energy. In order to avoid unnecessary waste, the installation of on-off devices is also used to control the passage of water energy. Today, the use of gas is discussed. Most people place gas cylinders outdoors, mainly due to safety needs, but they overlook one thing: it is difficult for users to identify the on-off state of the on-off device.

[0003] Normally, users judge the on-off device as off when the switch is clockwise and on when the switch is counterclockwise. Therefore, they must repeatedly control the left and right to know whether the on-off device is on or off. Over time, the knob of the on-off device and the valve body are prone to come loose. In addition, when children do not understand the direction of the switch and randomly rotate it, there is a risk. In addition, the above-mentioned types of users, such as young children, the elderly, the disabled, or people with poor eyesight, may experience some inconvenience when operating the on-off device. In addition, the position of the on-off device may be in a position that cannot be seen, and the user must rely on their sense of touch to control it. These practices may pose some risks.

[0027] Please see FIG. 1 to FIG. 8, the valve body structure with switch display function of the application, it includes: a valve body 1, it has in the top end an installation part 11, in the left and right two sides of the valve body 1 an input part 13, an output part 14, and in the bottom end of the valve body 1 a fuel inlet part 15, the fuel inlet part 15 can be connected to gas barrel, natural gas pipe, the input part 13 is installed by safety valve (not shown in the figure), the output part 14 is connected to the place (such as stove, water heater etc.) needing gas to be supplied, the input part 13, the output part 14 and the fuel inlet part 15 are mutually open, again the installation part 11 is provided with a control assembly 2, the control assembly 2 is partially buried in the installation part 11, the part of the control assembly 2 is exposed outside the installation part 11 and forms a actuating platform 21, the control assembly 2 limits and controls the open, closure between the input part 13, the output part 14;A valve knob 3, it is sleeved on the part of the control assembly 2 exposed in the installation part 11, the valve knob 3 is recessed with multiple finger grooves 31 around the outer periphery side to provide each finger of hand to hold control, and the rotation of the valve knob 3 controls the open, closure of the control assembly 2 between the fuel inlet part 15, the output part 14, again the position of the valve knob 3 sleeved on the control assembly 2 penetrates a combination hole 32, the exposed part of the control assembly 2 is inserted from the bottom end of the combination hole 32, and a screw 4 is inserted from the top end of the combination hole 32 and is locked on the control assembly 2;And an identification piece 5, it is movably assembled in a combination hole 33 of the valve knob 3, the combination hole 33 penetrates the top, bottom end of the valve knob 3, the identification piece 5 includes an identification part 51 and a actuating part 52, one end of the actuating part 52 is connected to the bottom surface of the identification part 51, the other end of the actuating part 52 penetrates the combination hole 33 and normally abuts on the actuating platform 12, again the rotation of the valve knob 3 controls the displacement of the identification piece 5, and when the valve knob 3 rotates and approaches the valve body 1, the actuating part 52 of the identification piece 5 abuts on the actuating platform 12 to make the identification part 51 exposed in the aperture of the combination hole 33, again when the valve knob 3 rotates and moves away from the valve body 1, the identification piece 5 gradually sinks in the combination hole 33 to make the identification part 51 be located in the combination hole 33.

[0028] According to the above description, in the dark place of the installation of the present application, the place where the line of sight is poor, or the place where the user (including the disabled, the elderly) cannot directly identify the opening or closing by visual means, the user only needs to rotate the valve knob 3 under normal switch operation. As long as the identification part 51 of the identification member 5 protrudes from the combined hole 33, the user will touch the protruding part of the identification part 51 during operation. In this way, it can be known that the rotation direction is the closing control. Conversely, as long as the identification part 51 cannot be touched during the rotation of the valve knob 3, it can be judged that the control direction is the opening control. Similarly, if the judgment can be made by visual means in the relevant place, it is more convenient for the user to directly observe whether the identification part 51 is protruding or sunken relative to the combined hole 33 by visual means. In this way, it can be quickly and easily judged whether the control assembly 2 is conducting fuel into the fuel inlet part 15 and the output part 14, or blocking the conduction between the fuel inlet part 15 and the output part 14. No matter where the installation place of the present application is, it is easier for the user to judge the opening and closing operation direction of the valve knob 3 and no misjudgment occurs. In this way, it can avoid the danger that may occur due to misjudgment, and can also maintain the service life of the valve knob 3 and the control assembly 2.

[0029] According to the above main description of the present application, the technical features and structure are further described in detail below. First, please see FIGS. 4-8. The recognition part 51 of the recognition member 5 is specially designed to provide the user with a more direct way to determine the direction by visual recognition. Therefore, the recognition part 51 is further divided into a direction recognition area 511 and a switch recognition area 512. The direction recognition area 511 is provided with an arrow recognition end 5111 at one end and a character recognition image 5112 engraved on the top surface of the direction recognition area 511. The switch recognition area 512 is provided with a character judgment image 5121 engraved on the top surface. The design of the arrow recognition end 5111 provides the user with a direct way to determine the rotation direction as opening or closing. The protrusion and sinking of the recognition part 51 relative to the combined hole 33 can provide more accurate control and prevent the problem of misjudgment and rotation in the wrong direction. The character recognition image 5112 and the character judgment image 5121 provide the user with a touch way to identify the direction of the valve knob 3 to be rotated as opening or closing. In addition, in order to match the structural feature design of the recognition member 5, the design of the combined hole 33 must also match the shape of the recognition part 51 of the recognition member 5. Therefore, the combined hole 33 is further divided into a first hole area 331 and a second hole area 332. The first hole area 331 and the second hole area 332 are connected, and the hole type of the first hole area 331 corresponds to the shape of the direction recognition area 511, which is an arc arrow hole type. The second hole area 332 corresponds to the shape of the switch recognition area 512, which is a round hole. The two side walls at the connection between the first hole area 331 and the second hole area 332 extend in opposite directions to form a stop rib 34. The stop rib 34 separates the installation of the direction recognition area 511 and the switch recognition area 512. The stop rib 34 is mainly designed to prevent foreign matter from entering the combined hole 33 and affecting the operation of the recognition member 5. Please see FIG. 4.

[0030] As described above, in order to prevent the recognition member 5 from coming out of the combined hole 33 when the valve knob 3 rotates away from the actuation platform 12, the bottom end of the stop rib 34 at the connection between the first hole area 331 and the second hole area 332 further forms a limiting part 35. When the valve knob 3 gradually rotates away from the actuation platform 12, the recognition part 51 of the recognition member 5 gradually sinks into the combined hole 33, and the connection between the recognition part 51 and the actuation part 52 is attached to the limiting part 35. Please see FIGS. 4-8.

[0031] In addition, in order to provide the installation between the identification member 5 and the combination hole 33 more convenient, the bottom end of the pressing portion 52 of the identification member 5 is further provided with a split groove 521 and a guide cone ring surface 53 around the split groove 521, the split groove 521 is provided by splitting the bottom end face of the pressing portion 52 towards one end of the connecting identification portion 51, and the guide cone ring surface 53 is formed on the outer circumferential surface of the pressing portion 52. In addition, the inner wall of the combination hole 33 is provided with a limiting rib 36, the limiting rib 36 limits the partial hole diameter of the combination hole 33. After the pressing portion 52 of the identification member 5 is inserted into the combination hole 33 and the guide cone ring surface 53 abuts against the limiting rib 36, the pressing portion 52 is elastically deformed and shrinks by the split groove 521, so that the pressing portion 52 can pass through the limiting rib 36 and then be elastically restored to be stopped by the limiting rib 36. In this way, the entire identification member 5 can be prevented from being pulled out of the combination hole 33. In addition, the position where the guide cone ring surface 53 is provided on the pressing portion 52 is formed with an outwardly protruding stop portion 54, which is mainly used to prevent the identification member 5 from being separated from the combination hole 33. In addition, in order to avoid the influence of foreign matter between the identification member 5 and the valve knob 3 for a long time, a spring 7 is further provided on the pressing portion 52 of the identification member 5, one end of the spring 7 abuts against the limiting rib 36, and the other end of the spring 7 abuts against a stop portion 54 protruding from the pressing portion 52, and the guide cone ring surface 53 is connected to the edge of the stop portion 54. In short, through the arrangement of the spring 7, normally the identification portion 51 of the identification member 5 will change from the state of protruding from the combination hole 33 to the state of sinking into the combination hole 33. However, if there is foreign matter between the pressing portion 52 and the limiting rib 36, the identification portion 51 of the identification member 5 cannot sink into the combination hole 33 during the process of the valve knob 3 from closing to opening, and moves upward together with the valve knob 3. In this way, the user cannot identify the opening or closing, and therefore the arrangement of the spring 7 can elastically drive the identification portion 51 of the identification member 5 to sink into the combination hole 33, so that the user can clearly judge the difference between opening and closing, as shown in FIGS. 9-11.

[0032] In addition, in order to provide a firm combination, the combination hole 32 is further divided into an upper hole section 321, a lower hole section 322 and a separation rib 323 between the upper hole section 321 and the lower hole section 322. The hole diameter of the upper hole section 321 is larger than that of the lower hole section 322. The upper hole section 321 is in communication with the combination hole 33. The separation rib 323 is located at one end face of the upper hole section 321 and further has a plurality of anti-slip ribs 324. The screw 4 is inserted into the combination hole 32 and abuts against the anti-slip ribs 324 when it is tightly locked with the control assembly 2. The control assembly 2 is partially inserted into the lower hole section 322 and abuts against the separation rib 323. The separation rib 323 can prevent the screw 4 from being exposed and can avoid the mutual friction and abrasion between the screw 4 and the control assembly 2 when the valve knob 3 is rotated. In addition, the anti-slip ribs 324 can prevent the gasket 6 from rotating when the gasket 6 is placed between the upper hole section 321 and the separation rib 323 (the gasket 6 is mainly shown in the drawings). The friction between the gasket 6 and the anti-slip ribs 324 is caused by the contact between them. The gasket 6 is made of rubber material. Please refer to Figs. 4 to 8.

[0033] Finally, the screw 4 further has an adjusting groove 41 at the top end. The adjusting groove 41 is in the shape of a straight groove, a cross-shaped groove (not shown) or a rice-shaped groove (not shown). The user can use a hand tool to adjust the tightness of the valve knob 3 relative to the control assembly 2.
