Description

Technical Field

[0001] This utility model relates to the field of gas meter technology, specifically to a motor valve position detection device and a gas meter. Background Technology

[0002] A diaphragm gas meter is a metering device used to measure gas flow rate, widely used in homes, businesses, and industries. Its working principle is based on the reciprocating motion of a diaphragm; the gas flow rate is determined by calculating the number of diaphragm movements. The motor valve controls the gas flow, ensuring gas supply and playing a crucial role in user safety. It promptly transmits valve-closing information after the motor valve closes, facilitating safe use by the user.

[0003] Currently, motor valves with a closed position can achieve the function of being fully closed and can be installed in a small housing. The disadvantage is that they use a magnetic sensing method to determine whether they are fully closed, which is greatly affected by the performance of the magnet and reed switch. Different batches of motor valves have significant differences in function, and the accuracy of closing position cannot be guaranteed. Utility Model Content

[0012] Beneficial effects: The first and second triggers are bent. In the first state, the third trigger causes the first and second triggers to come into contact and store potential energy. In the second state, the third trigger moves away from the first trigger, and the first and second triggers release their potential energy, restoring the original state of the interval setting.

[0013] In one optional embodiment, the fixing assembly includes a second fixing member, a fixing cover, and a push-button switch. The second fixing member is adapted to be connected to the valve body, the fixing cover is connected to the second fixing member, a first end of the push-button switch is disposed between the fixing cover and the second fixing member, and a second end of the push-button switch extends from the second fixing member and is adapted to face the valve.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The following is combined Figures 1 to 11 The following describes embodiments of the present invention.

[0029] Example 1 In this embodiment, as Figure 1 and Figure 2As shown, a motor valve position detection device is provided, including a fixing component 10, a triggering component 20, and a signal conduction structure 30. The fixing component 10 is adapted to be connected to the valve body 41. The triggering component 20 includes a first trigger 21, a second trigger 22, and a third trigger 23. The first trigger 21 and the second trigger 22 are respectively connected to the fixing component 10, and the third trigger 23 is adapted to be connected to the valve 42. Two signal conduction structures 30 are provided, and the two signal conduction structures 30 are electrically connected to the first trigger 21 and the second trigger 22 respectively. The signal conduction structure 30 is a signal wire. The motor valve position detection device has a first state and a second state. In the first state, the third trigger 23 abuts against the first trigger 21, and the first trigger 21 is electrically connected to the second trigger 22. In the second state, the third trigger 23 is spaced apart from the first trigger 21 and the second trigger 22, and the first trigger 21 and the second trigger 22 are spaced apart.

[0030] The motor valve position detection device of this embodiment achieves electrical signal conduction between the first trigger 21 and the second trigger 22 through the contact collision of the third trigger 23. It is less affected by external factors and will not be subject to strong magnetic interference. Moreover, the signal switching is achieved through simple contact and separation. The structure is simple and compact, occupies little space, and is suitable for installation in small spaces such as gas meter housings.

[0031] Specifically, the motor valve has an open state and a closed state, such as... Figure 1 As shown in Figure 2, the first state corresponds to the closed state of the motor valve. When the valve 42 of the motor valve is closed, the third trigger 23 abuts against the first trigger 21. After being subjected to force, the first trigger 21 gradually tilts and abuts against the second trigger 22, thus connecting the circuit between the first trigger 21 and the second trigger 22 and transmitting the closed signal. As shown in Figure 2, the second state corresponds to the open state of the motor valve. When the valve 42 of the motor valve is open, the third trigger 23 is spaced apart from the first trigger 21. The first trigger 21 is not subjected to force and is spaced apart from the second trigger 22. The circuit is not connected and the closed signal will not be transmitted.

[0032] It should be noted that when the state of valve 42 is switched, the movement direction of valve 42 is consistent with the movement direction of the third trigger 23. Only when the movement of valve 42 can it drive the movement of the third trigger 23, thereby realizing the contact or separation of the first trigger 21 and the second trigger 22.

[0033] In this embodiment, as Figure 1 and Figure 2As shown, the first trigger 21 includes a first abutting part 211 and a first fixing part 212. The first abutting part 211 and the first fixing part 212 are connected in a bent shape. The second trigger 22 includes a second abutting part 221 and a second fixing part 222. The second abutting part 221 and the second fixing part 222 are connected in a bent shape. The first fixing part 212 and the second fixing part 222 are respectively disposed in the first fixing part 11. The first abutting part 211 has a protrusion 2111. In the first state, the third trigger 23 abuts against the protrusion 2111, and the first abutting part 211 abuts against the second abutting part 221.

[0034] Specifically, in this embodiment, the first trigger 21 and the second trigger 22 are both springs, and the third trigger 23 is a pull rod. The pull rod is connected to the valve 42 of the motor valve. When the position of the valve 42 changes, it drives the pull rod to change its position up and down, thereby realizing the abutment, compression and separation of the first abutment part 211.

[0035] It is worth noting that the first trigger 21 and the second trigger 22 are bent. In the first state, the third trigger 23 causes the first trigger 21 and the second trigger 22 to come into contact and store potential energy. In the second state, the third trigger 23 moves away from the first trigger 21, and the first trigger 21 and the second trigger 22 release their potential energy and return to the original state of the interval setting.

[0036] In this embodiment, as Figure 1 and Figure 2 As shown, the fixing component 10 includes a first fixing member 11 and a sleeve 12. The sleeve 12 is adapted to be connected to the valve body 41. The first fixing member 11 is disposed inside the sleeve 12. Two grooves are spaced apart on the first fixing member 11. The first end of the first trigger member 21 and the first end of the second trigger member 22 are respectively disposed in the two grooves. The third trigger member 23 is slidably disposed inside the sleeve 12. In the first state, the third trigger member 23 abuts against the first trigger member 21, and the second end of the first trigger member 21 abuts against the second end of the second trigger member 22. In the second state, the second end of the first trigger member 21 and the second end of the second trigger member 22 are spaced apart.

[0037] It is worth noting that the third trigger 23 moves with the valve 42 to abut against the first trigger 21, so that the first trigger 21 abuts against the second trigger 22, and the electrical signal is conducted. The structure is simple and easy to install and maintain.

[0038] In this embodiment, as Figure 1 and Figure 2 As shown, the fixing component 10 also includes a first sealing structure 13, which is disposed on the sleeve 12.

[0039] Specifically, the first sealing structure 13 is a sealing sleeve, which is fitted onto the sleeve 12; the sealing sleeve has a spring opening so that the first trigger 21 and the second trigger 22 can extend through the spring opening and connect to the signal conduction structure 30.

[0040] It is worth noting that by setting the first sealing structure 13, the fixing component 10 is protected, preventing foreign objects from entering the fixing component 10 and causing abnormal malfunctions such as accidental contact.

[0041] Working principle: When valve 42 is fully closed, it drives the third trigger 23 to its highest position. The third trigger 23 applies upward pressure to the first trigger 21, causing the first trigger 21 to bend and contact the second trigger 22, triggering an electrical connection. The external contacts of the first trigger 21 and the second trigger 22 are also electrically connected. The electrical connection between the external contacts of the first trigger 21 and the second trigger 22 determines whether the valve is fully closed. When valve 42 is opened, it drives the third trigger 23 downward, causing the first trigger 21 to be released from pressure and return to its original position. The electrical connection between the first trigger 21 and the second trigger 22 is disconnected, as is the electrical connection between their external contacts.

[0042] Example 2 The difference between Example 2 and Example 1 is as follows: In this embodiment, as Figure 3 and Figure 4 As shown, the fixing assembly 10 includes a second fixing member 14, a fixing cover 15, and a push-button switch 16. The second fixing member 14 is adapted to be connected to the valve body 41, and the fixing cover 15 is connected to the second fixing member 14. The first end of the push-button switch 16 is disposed between the fixing cover 15 and the second fixing member 14, and the second end of the push-button switch 16 extends out from the second fixing member 14 and is adapted to face the valve 42. The first trigger member 21 and the second trigger member 22 are spaced apart at the second end of the push-button switch 16. In the first state, the third trigger member 23 abuts against the push-button switch 16 and simultaneously abuts against the first trigger member 21 and the second trigger member 22. The first trigger member 21 and the second trigger member 22 are electrically connected. In the second state, the third trigger member 23 is spaced apart from the first trigger member 21 and the second trigger member 22 respectively, and the first trigger member 21 and the second trigger member 22 are electrically disconnected.

[0043] Specifically, in this embodiment, the first trigger 21 and the second trigger 22 are contacts, and the first trigger 21 and the second trigger 22 are respectively disposed diagonally opposite the push button switch 16, and the signal conduction structure 30 is welded to the contacts; the third trigger 23 is a boss that moves with the valve 42.

[0044] Specifically, in the first state, the third trigger 23 abuts against the button switch 16, as well as the first trigger 21 and the second trigger 22. When the button switch 16 receives pressure, the first trigger 21 and the second trigger 22 diagonally opposite each other are turned on, thereby connecting the wires connected to the diagonal contacts and outputting a closed signal.

[0045] It is worth noting that the first trigger 21 and the second trigger 22 are integrated on the push-button switch 16, which simplifies the structural design. The electrical connection between the first trigger 21 and the second trigger 22 can be achieved through a single contact action, which simplifies the operation logic and reduces the assembly difficulty.

[0046] In this embodiment, as Figure 3 and Figure 4 As shown, the fixing component 10 also includes a fastener 17, which passes through the fixing cover 15 and is fastened within the second fixing member 14.

[0047] Specifically, the fastener 17 is a screw, and the fixing cover 15 is connected to the second fixing member 14 by the screw, fixing the push button switch 16 between the two to prevent the push button switch 16 from moving.

[0048] It is worth noting that the fastener 17 enables the detachable connection between the fixing cover 15 and the second fixing member 14, which facilitates installation and subsequent maintenance.

[0049] Working principle: When valve 42 is closed, valve 42 drives the third trigger 23 to the highest position. At this time, the third trigger 23 presses against the button switch 16, the first trigger 21 and the second trigger 22. The first trigger 21 and the second trigger 22, which are diagonally arranged on the button switch 16, are electrically connected. The electrical connection between the two contacts is used to determine whether the valve is closed. When valve 42 is opened, the third trigger 23 moves downward with valve 42 and is no longer in contact with the button switch 16. The first trigger 21 and the second trigger 22, which are diagonally arranged, are electrically disconnected.

[0050] Example 3 The difference between Example 3 and Example 1 is as follows: In this embodiment, as Figure 5 and Figure 6As shown, the fixing component 10 includes a third fixing member 18, which is adapted to be connected to the valve body 41. A third trigger member 23 is slidably disposed within the third fixing member 18. A first trigger member 21 and a second trigger member 22 are spaced apart on the inner wall of the third fixing member 18. In a first state, the third trigger member 23 simultaneously abuts against the first trigger member 21 and the second trigger member 22, and the first trigger member 21 and the second trigger member 22 are electrically connected. In a second state, the third trigger member 23 is spaced apart from the first trigger member 21 and the second trigger member 22, and the first trigger member 21 and the second trigger member 22 are electrically disconnected.

[0051] Specifically, such as Figure 5 and Figure 6 As shown, the first trigger 21 and the second trigger 22 are spring pins, and the first trigger 21 and the second trigger 22 are at the same height. The third trigger 23 is a metal ring, which is suitable for being sleeved on the valve 42.

[0052] Specifically, the third trigger element 23 is a copper ring, which is installed on the valve 42 and changes position as the valve 42 moves up and down.

[0053] It is worth noting that the spring pins are at the same height, ensuring that the metal ring abuts against the two triggers simultaneously, avoiding signal misjudgment due to asynchronous contact and ensuring detection accuracy; the third fixing member 18 provides an integrated installation space for the internal components, and the first and second triggers 22 are directly set on the inner wall, shortening the trigger path and improving the timeliness and accuracy of signal triggering.

[0054] In this embodiment, as Figure 5 and Figure 6 As shown, the fixing assembly 10 also includes a second sealing structure 19, which is disposed on the third fixing member 18.

[0055] Specifically, the second sealing structure 19 is a sealing sleeve, which is fitted onto the third fixing member 18.

[0056] It is worth noting that by setting the second sealing structure 19, the fixing component 10 is protected, preventing foreign objects from entering the third fixing component 18 and causing abnormal malfunctions such as accidental contact.

[0057] Working principle: When valve 42 is closed, the third trigger 23 reaches its highest position. At this time, the third trigger 23 is in contact with the first trigger 21 and the second trigger 22 simultaneously. The first trigger 21 and the second trigger 22 are in electrical contact. Whether the valve is closed is determined by the electrical contact between the first trigger 21 and the second trigger 22. When valve 42 is opened, the third trigger 23 moves downward with valve 42 and disengages from the first trigger 21 and the second trigger 22. The electrical connection between the first trigger 21 and the second trigger 22 is broken.

[0058] Example 4 In this embodiment, a gas meter is provided, such as Figure 7 As shown, the device includes the motor valve positioning detection device and the motor valve of Embodiment 1; the motor valve includes a valve body 41 and a valve 42, the valve 42 is movably disposed in the valve body 41, the fixing component 10 is connected to the valve body 41, and the third trigger 23 is connected to the valve 42.

[0059] Example 5 The difference between Example 5 and Example 4 is that in this example, a gas meter is provided, such as... Figure 8 and Figure 9 As shown, the gas meter includes the motor valve position detection device and the motor valve of Embodiment 2.

[0060] Example 6 The difference between Example 6 and Example 4 is that, in this example, a gas meter is provided, such as... Figure 10 and Figure 11 As shown, the gas meter includes the motor valve position detection device and the motor valve of Embodiment 3.
