Description

Technical Field

[0001] This application relates to the field of valve maintenance technology, and in particular to a valve counting structure. Background Technology

[0002] As a key component of industrial equipment, valves play a vital role in many industries. For valves that require regular maintenance, especially those with a limited service life, workers need to repair or replace some parts of the valve after a certain number of uses to keep the valve equipment in good operating condition.

[0003] The existing method for monitoring valve opening and closing involves hanging an operation card near the valve equipment. When the valve equipment is opened or closed, the staff manually fills in the operation card, which records the number of times the valve equipment is opened and closed and the time. Based on the records on the operation card, the staff regularly repairs or replaces some parts of the valve equipment.

[0004] The above method for recording the number of times valves are opened and closed requires staff to record in real time. If staff miss the record of valve opening and closing, the maintenance time of the valves may be missed, resulting in damage to the valves. There is room for improvement. Utility Model Content

[0005] In order to automatically record valve opening and closing data, enabling staff to observe the number of times the valves are used in real time, thereby reducing the possibility of valve damage, this application provides a valve counting structure.

[0006] This application provides a valve counting structure, which adopts the following technical solution:

[0007] A valve counting structure includes a bracket, a base, and a valve stem. The bracket is mounted on the side wall of the base, and the valve stem is rotatably connected to the side wall of the base. A limit block is fixed to the side wall of the valve stem. A connecting hole and a rotating cavity are formed in the side wall of the bracket. The side wall of the limit block is slidably connected to the inner wall of the rotating cavity. The opening of the connecting hole is located in the inner wall of the rotating cavity. A push rod is elastically connected to the inner wall of the connecting hole. The end of the push rod abuts against the side wall of the limit block. A counting element is provided at the end of the push rod away from the valve stem.

[0008] By adopting the above technical solution, when the valve moves from open to closed, the valve stem drives the limiting block to slide on the inner wall of the rotating chamber. At this time, the end of the push rod near the valve stem abuts against the side wall of the limiting block. Under the action of the limiting block, the push rod slides on the inner wall of the connecting hole. The push rod triggers the switch of the counter. When the valve moves from closed to open, the push rod rebounds under the action of elasticity, and the switch of the counter resets, completing one count. This setting realizes automatic recording of valve opening and closing data, allowing staff to observe the number of times the valve is used in real time, thereby reducing the possibility of valve damage.

[0009] Optionally, a locking block is fixed to the side wall of the bracket. The locking block is located on the inner wall of the rotary cavity, and the side wall of the locking block away from the valve stem abuts against the side wall of the top rod.

[0010] By adopting the above technical solution, the push rod slides on the inner wall of the connection hole under the restriction of the locking block, reducing the possibility of the push rod sliding out of the connection hole and increasing the stability of the valve counting structure during operation.

[0011] Optionally, a limiting piece is fixed to the side wall of the valve stem, and the side wall of the limiting piece abuts against the side wall of the limiting block.

[0012] By adopting the above technical solution, the setting of the limiting plate reduces the possibility of the limiting block sliding on the valve stem side wall, making the fixing of the limiting block on the valve stem side wall more reliable and increasing the stability of the limiting block when working on the valve stem side wall.

[0013] Optionally, the valve stem has several stops installed on its side wall, and the limiting block has several grooves on its inner wall, with the side wall of the stops abutting against the inner wall of the grooves.

[0014] By adopting the above technical solution, the combination of the stop block and the stop groove improves the connection stability between the valve stem and the limit block during the valve stem rotation process, reduces the shaking of the limit block on the side wall of the valve stem, and further ensures the counting accuracy of the push rod.

[0015] Optionally, the side wall of the base is provided with a telescopic groove, the side wall of the bracket is slidably connected to the inner wall of the telescopic groove, a locking pin is installed on the side wall of the base, the end of the locking pin abuts against the side wall of the bracket, and the stops are respectively spaced along the axial and circumferential directions of the valve stem.

[0016] By adopting the above technical solution, the operator can adjust the position of the limit block on the valve stem side wall by using the stop block, and adjust the position of the bracket on the base side wall by using the telescopic groove, so that the position of the bracket corresponds to that of the limit block. At this time, the bracket is fixed to the side wall of the base by the locking pin, and both the bracket and the limit block work stably. This setting expands the working range of the valve equipment.

[0017] Optionally, the valve stem has several fixing holes on its side wall, and the side wall of the stop block abuts against the inner wall of the fixing holes.

[0018] By adopting the above technical solution, the stop block is locked in the inner wall of the fixing hole. When installing the limit block, the staff will lock the stop block required for the installation of the limit block into the inner wall of the fixing hole, and then remove and recycle the stop block away from the limit block, which facilitates the installation and removal of the limit block.

[0019] Optionally, the side wall of the bracket is provided with a stepped groove, and the end of the locking pin abuts against the inner wall of the stepped groove.

[0020] By adopting the above technical solution, when the operator changes the relative position of the bracket on the side wall of the base, the operator changes the position of the bracket on the side wall of the base through the telescopic groove, and then locks the side wall of the bracket by locking pin. At this time, the end of the locking pin is engaged with the inner wall of the stepped groove. This setting makes the locking pin engaged with the stepped groove more reliable, and further increases the stability of the valve equipment during operation.

[0021] Optionally, the locking pins are installed on both sides of the base, with the two locking pins arranged opposite each other.

[0022] By adopting the above technical solution, the two locking pins are simultaneously engaged with the inner wall of the bracket, which further increases the reliability of the bracket being fixed on the side wall of the base. At the same time, the two locking pins are located on both sides of the base, which reduces the possibility of the bracket shifting due to uneven force and thus affecting the operation of the valve equipment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the valve is rotated to the closed position, the limit block drives the push rod to slide on the inner wall of the connecting hole. At this time, the push rod triggers the switch of the counter. When the valve is rotated to the open position, the push rod pops out of the connecting hole under the action of elasticity. At this time, the counter switch is reset, and the counter count is incremented by one. When the counter count reaches the number of times the valve has been used, the staff will repair or replace the internal parts of the valve. This setting realizes automatic recording of the valve opening and closing data, allowing the staff to observe the number of times the valve has been used in real time, thereby reducing the possibility of valve damage.

[0025] 2. When the valve is opened or closed, the valve stem drives the limit block to rotate on the inner wall of the rotary chamber. With the cooperation of the stop block on the side wall of the valve stem and the stop groove on the inner wall of the limit block, the limit block rotates stably on the side wall of the valve stem. With the support of the limit plate, the limit block is stably fixed to the side wall of the valve stem. Attached Figure Description

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] This application discloses a valve counting structure.

[0034] Example 1

[0035] Reference Figure 1 A valve counting structure includes a bracket 1, a base 2, and a valve stem 3. The bracket 1 is mounted on the side wall of the base 2, and the valve stem 3 is rotatably fixed to the side wall of the bracket 1. A limit block 4 is fixed to the side wall of the valve stem 3. A rotating cavity 6 is opened in the side wall of the bracket 1. The side wall of the limit block 4 is slidably connected to the inner wall of the rotating cavity 6. When the valve device is opened or closed, the valve stem 3 drives the limit block 4 to slide on the inner wall of the rotating cavity 6. This arrangement facilitates the counting process of the valve counting structure.

[0036] Reference Figure 1 The side wall of the bracket 1 is provided with several limiting grooves 17. In this embodiment, two limiting grooves 17 are preferably provided, and the two limiting grooves 17 are spaced apart. Both limiting grooves 17 are located on the inner wall of the rotary cavity 6. When the valve stem 3 drives the limiting block 4 to rotate on the inner wall of the rotary cavity 6, the side wall of the limiting block 4 abuts against the inner wall of the limiting groove 17. Under the limiting effect of the limiting groove 17, the rotation process of the limiting block 4 stops. This setting effectively increases the safety of the limiting block 4 during use, so that the opening and closing process of the valve equipment is within a safe range.

[0037] Reference Figure 2The valve stem 3 has several stops 11 fixed on its side wall, and the inner wall of the limiting block 4 has several grooves 12. The stops 11 and the grooves 12 are arranged correspondingly. In this embodiment, two stops 11 are preferred. The two stops 11 are arranged at intervals on the side wall of the valve stem 3. With the cooperation of the stops 11 and the grooves 12, the limiting block 4 rotates at the same time when the valve stem 3 rotates. The arrangement of the stops 11 and the grooves 12 makes the rotation process of the limiting block 4 more reliable and increases the stability of the limiting block 4 when it rotates.

[0038] Reference Figure 3 A limiting piece 10 is fixed to the side wall of the valve stem 3. The side wall of the limiting piece 10 abuts against the side wall of the limiting block 4. When installing the limiting block 4, the operator first fixes the limiting piece 10 to the side wall of the valve stem 3, and then fixes the limiting block 4 to the side wall of the valve stem 3. The setting of the limiting piece 10 reduces the possibility of the limiting block 4 sliding on the side wall of the valve stem 3, making the working process of the limiting block 4 on the side wall of the valve stem 3 more stable.

[0039] Reference Figure 2 and Figure 3 The side wall of the bracket 1 is provided with a counter 8. In this embodiment, the counter 8 is preferably a mechanical counter. The counter 8 is used to count the number of times the valve equipment is opened and closed. The side wall of the bracket 1 is provided with a connection hole 5. One end of the connection hole 5 is connected to the rotary cavity 6, and the other end of the connection hole 5 is close to the counter.

[0040] Reference Figure 2 and Figure 3 A push rod 7 is elastically connected to the inner wall of the connecting hole 5. A locking block 9 is fixed to the side wall of the bracket 1. The locking block 9 is located at the opening of the connecting hole 5 near the limit block 4. The setting of the locking block 9 reduces the possibility of the push rod 7 sliding out of the connecting hole 5. A fixing nut 18 is fixed to the side wall of the bracket 1. The fixing nut 18 is located at the inner wall of the connecting hole 5 near the counter 8. The setting of the fixing nut 18 provides an installation environment for the counter 8. When the valve equipment moves from open to closed, the limit block 4 drives the push rod 7 to slide towards the counter 8. At this time, the push rod 7 triggers the switch of the counter 8. When the valve equipment moves from closed to open, the push rod 7 slides towards the limit block 4 under the elastic action. At this time, the switch of the counter 8 is reset, and the count of the counter 8 is incremented by one.

[0041] In Embodiment 1 of this application, the implementation principle of a valve counting structure is as follows: When the valve is opened or closed, the valve stem 3 drives the limiting block 4 to slide on the inner wall of the rotating cavity 6. Subsequently, the side wall of the limiting block 4 abuts against the end of the push rod 7 away from the counting element 8. Under the action of the limiting block 4, the push rod 7 slides towards the counting element 8, triggering the switch of the counting element 8. When the valve is closed, the limiting block 4 moves away from the push rod 7. Under the action of elasticity, the push rod 7 slides towards the limiting block 4, the switch of the counting element 8 is reset, and the count of the counting element 8 is incremented by one. When the count of the counting element 8 reaches the service life of the valve, the staff repairs or replaces the parts of the valve. This setting realizes automatic recording of the valve opening and closing data, allowing the staff to observe the number of times the valve is used in real time, thereby reducing the possibility of valve damage.

[0042] Example 2

[0043] Example 2 differs from Example 1 in that: (Refer to...) Figure 4 and Figure 5 In this embodiment, several stop blocks 11 are spaced apart in the axial and circumferential directions of the valve stem 3. The side wall of the base 2 is provided with a telescopic groove 13. The side wall of the bracket 1 is slidably connected to the inner wall of the telescopic groove 13. When the operator changes the position of the limiting block 4 on the side wall of the valve stem 3, the operator removes the limiting block 4 through the stop block 11 and reinstalls the limiting block 4 on the side wall of the valve stem 3. Then, the relative position of the bracket 1 on the side wall of the base 2 is adjusted so that the position of the bracket 1 corresponds to that of the limiting block 4. This setting increases the working range of the valve equipment.

[0044] Reference Figure 5 The valve stem 3 has several fixing holes 15 on its side wall, and the fixing holes 15 are corresponding to the stop blocks 11. When the operator installs the limit block 4, the operator will put the stop block 11 into the inner wall of the fixing hole 15 corresponding to the position to be installed, and then install the limit block 4. At this time, the stop block 11 and the limit block 4 cooperate, and the limit block 4 works stably on the side wall of the valve stem 3. The setting of the fixing holes 15 makes it easy for the operator to install and remove the limit block 4, which simplifies the operator's operation.

[0045] Reference Figure 5The bracket 1 has stepped slots 16 on both sides. A locking pin 14 is slidably connected to the side wall of the base 2, with the end of the locking pin 14 abutting against the inner wall of the stepped slot 16. A blocking buckle 19 is slidably connected to the side wall of the base 2, with the side wall of the blocking buckle 19 abutting against the side wall of the locking pin 14. When the operator adjusts the position of the bracket 1 on the side wall of the base 2, the operator controls the locking pin 14 to slide towards the stepped slot 16, and then the end of the locking pin 14 abuts against the side wall of the stepped slot 16. At this time, the operator manipulates the blocking buckle 19 to approach the locking pin 14, and the side wall of the locking pin 14 abuts against the end of the blocking buckle 19. This setting restricts the sliding of the bracket 1 on the inner wall of the base 2, thus fixing the bracket 1 in a relatively fixed position on the side wall of the base 2. The locking pins 14 slidably connected to both sides of the base 2 further increase the ability of the locking pins 14 to restrict the sliding of the bracket 1, increasing the reliability of fixing the bracket 1 on the side wall of the base 2.

[0046] According to Embodiment 2 of this application, the implementation principle of a valve counting structure is as follows: When it is necessary to change the working range of the valve equipment, the operator adjusts the relative position of the limiting block 4 on the side wall of the valve stem 3 by using the stop block 11, and then adjusts the relative position of the bracket 1 on the side wall of the base 2. After the adjustment is completed, the operator controls the end of the locking pin 14 to abut against the inner wall of the stepped groove 16, which ultimately changes the working range of the valve equipment. When the output force of the valve equipment is different, the relative position of the limiting block 4 can be changed, making the working process of the valve equipment more stable.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
