[0002] A valve is a device installed in a fluid transport system to control the flow of media. An automatic counting device for the number of rotations of the valve handwheel is a device used to automatically record the number of rotations of the valve handwheel. Through sensors or mechanical transmission structures, it monitors the rotation of the handwheel in real time, converts the number of rotations into electrical signals or digital information, and presents the information intuitively through a display screen or other components after processing, thereby realizing the automatic statistics of the number of rotations of the handwheel during the opening and closing of the valve.

[0003] The existing automatic counting device for the number of rotations of the valve opening and closing handwheel is inconvenient to disassemble and assemble quickly, making regular maintenance inconvenient and eventually affecting the counting accuracy of the device.

[0004] Therefore, an automatic counting device for the number of rotations of the valve opening and closing handwheel is needed to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the above-mentioned automatic counting device for the number of rotations of a valve opening and closing handwheel, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide an automatic counting device for the number of rotations of a valve opening and closing handwheel, which solves the problem that "existing automatic counting devices for the number of rotations of a valve opening and closing handwheel are inconvenient to disassemble and assemble quickly, resulting in inconvenient regular maintenance and affecting the counting accuracy of the device over time".

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic counting device for the number of rotations of a valve opening / closing handwheel, comprising:

[0009] A valve body, the top of which is rotatably connected to a handwheel, and a counter is provided on the outside of the handwheel;

[0010] The disassembly and assembly unit is located outside the counter. The disassembly and assembly unit includes a positioning rod, a sleeve block and a clamp, which are used to quickly disassemble and assemble the counter so that operators can maintain the counter.

[0011] A limiting unit is located outside the disassembly and assembly unit. The limiting unit includes a locking tooth and a locking block, which are used to limit the handwheel after it has been rotated to prevent it from continuing to rotate and causing leakage of the medium inside the valve body. When the valve body is in use and it is necessary to record the number of rotations of its handwheel, a counter is installed above the valve body through the disassembly and assembly unit. The counter can record the number of rotations of the handwheel. Under the restriction of the limiting unit, the handwheel after it has been rotated can be limited to prevent it from continuing to rotate.

[0012] As a preferred embodiment of the automatic counting device for the number of rotations of the valve opening and closing handwheel described in this utility model, the disassembly and assembly unit includes a vertical rod fixedly installed on the top surface of the valve body, a placement plate fixedly installed on the top of the vertical rod, a positioning rod fixedly installed on the top surface of the placement plate, and a sleeve block fixedly installed on the outer wall of the counter.

[0013] In a preferred embodiment of the automatic counting device for the number of rotations of the valve opening and closing handwheel described in this utility model, a rod frame is fixedly installed on the top surface of the placement plate, a collar is slidably provided on the outer wall of the rod frame, a push rod is fixedly installed on the outer wall of the collar, a clamp is fixedly installed on the side wall of the push rod, a connecting plate is hinged to the end of the push rod, a sleeve plate is hinged to the end of the connecting plate, a spring is fixedly installed on the side wall of the sleeve plate, a sliding rod is slidably provided inside the sleeve plate, and a fixing block is fixedly installed at the end of the sliding rod.

[0014] As a preferred embodiment of the automatic counting device for the number of rotations of the valve opening and closing handwheel described in this utility model, there are four positioning rods, divided into two groups, symmetrically distributed around the center line of the top surface of the placement plate. Under the constraint of the four positioning rods, the counter can be positioned and installed on the top surface of the placement plate.

[0015] In a preferred embodiment of the automatic counting device for the number of rotations of the valve opening and closing handwheel described in this utility model, the inner side of the clamp is engaged with the outer wall of the positioning rod, and the side wall of the clamp is slidably disposed with the top surface of the sleeve block. Under the restriction of the clamp, the sleeve block and the positioning rod are stably sleeved.

[0016] As a preferred embodiment of the automatic counting device for the number of rotations of the valve opening and closing handwheel described in this utility model, the limiting unit includes a threaded rod sleeved inside the upright, a sliding plate rotatably connected to the end of the threaded rod, a limit rod slidably disposed inside the sliding plate, a locking block fixedly installed on the side of the sliding plate away from the threaded rod, and locking teeth disposed on the side of the locking block away from the sliding plate.

[0017] As a preferred embodiment of the automatic counting device for the number of rotations of the valve opening and closing handwheel described in this utility model, wherein: the outer wall of the locking teeth is fixedly installed with the outer wall of the handwheel, and the locking teeth are distributed circumferentially around the center of the handwheel. Under the locking and limiting of the locking block and the locking teeth, the handwheel can be prevented from continuing to rotate.

[0018] As a preferred embodiment of the automatic counting device for the number of rotations of the valve opening and closing handwheel described in this utility model, the outer wall of the threaded rod is threadedly fitted with the inner wall of the upright, and the end of the limiting rod is fixedly installed on the outer wall of the upright. Under the sliding restriction of the sliding plate and the limiting rod, the rotating threaded rod can push the sliding plate rotatably connected to its end.

[0019] The beneficial effects of this utility model are as follows: When installing the counter, the sleeve plate is pushed to slide along the slide rod and compress the spring. The connecting plate pushes the push rod, so that the collar slides along the rod frame. After the sleeve block of the counter is aligned with the positioning rod of the placement plate and sleeved, the sleeve plate is released. The spring returns to its original position and drives the sleeve plate to move back. The connecting plate pulls the push rod, so that the clamp engages with the positioning rod and presses the sleeve block, thus realizing the quick installation of the counter and facilitating maintenance by operators.

[0020] After the handwheel has finished rotating, rotate the threaded rod. Under the restriction of the limit rod, the threaded rod pushes the slide plate to move, so that the slide plate drives the locking block to engage with the locking teeth of the handwheel, thereby restricting the rotation of the handwheel and preventing leakage of the medium inside the valve body.

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides an automatic counting device for the number of rotations of a valve opening / closing handwheel, comprising:

[0035] A valve body 100 is provided, and a handwheel 101 is rotatably connected to the top of the valve body 100. A counter 102 is provided on the outside of the handwheel 101.

[0036] The disassembly and assembly unit 200 is located outside the counter 102. The disassembly and assembly unit 200 includes a positioning rod 203, a sleeve block 204 and a clip 208, which are used to quickly disassemble and assemble the counter 102 so that the operator can maintain the counter 102.

[0037] The limiting unit 300 is located outside the disassembly unit 200. The limiting unit 300 includes a locking tooth 301 and a locking block 305, which are used to limit the handwheel 101 after it has been rotated, so as to prevent it from continuing to rotate and causing leakage of the medium inside the valve body 100.

[0038] When the valve body 100 is in use and the number of rotations of its handwheel 101 needs to be recorded, the counter 102 is installed above the valve body 100 through the disassembly and assembly unit 200. The counter 102 can record the number of rotations of the handwheel 101. Under the restriction of the restriction unit 300, the handwheel 101 can be restricted after it has finished rotating to prevent it from continuing to rotate.

[0039] Example 2

[0040] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows:

[0041] The disassembly and assembly unit 200 includes a vertical rod 201 fixedly installed on the top surface of the valve body 100, a placement plate 202 fixedly installed at the top of the vertical rod 201, a positioning rod 203 fixedly installed on the top surface of the placement plate 202, a sleeve block 204 fixedly installed on the outer wall of the counter 102, a rod frame 205 fixedly installed on the top surface of the placement plate 202, a collar 206 slidably provided on the outer wall of the rod frame 205, a push rod 207 fixedly installed on the outer wall of the collar 206, a clamp 208 fixedly installed on the side wall of the push rod 207, a connecting plate 209 hinged to the end of the push rod 207, a sleeve plate 210 hinged to the end of the connecting plate 209, a spring 211 fixedly installed on the side wall of the sleeve plate 210, a sliding rod 212 slidably provided inside the sleeve plate 210, and a fixing block 213 fixedly installed at the end of the sliding rod 212.

[0042] There are four positioning rods 203, which are divided into two groups and symmetrically distributed around the center line of the top surface of the placement plate 202. Under the constraint of the four positioning rods 203, the counter 102 can be positioned and installed on the top surface of the placement plate 202.

[0043] The inner side of the clip 208 is engaged with the outer wall of the positioning rod 203, and the side wall of the clip 208 is slidably disposed with the top surface of the sleeve block 204. Under the restriction of the clip 208, the sleeve block 204 and the positioning rod 203 are stably sleeved.

[0044] When using the counter 102, it needs to be installed on the top surface of the placement plate 202. At this time, pushing the sleeve 210 causes it to slide on the outer wall of the slide rod 212, compressing the spring 211 fitted on the outer wall of the slide rod 212. Since the end of the connecting plate 209 is hinged to the sleeve 210 and the push rod 207, under its constraint, the pushing sleeve 210 pushes the push rod 207 through the connecting plate 209, causing the collar 206 fixedly installed at the end of the push rod 207 to slide on the outer wall of the rod holder 205. This causes the outer wall of the counter 102 to... The fixedly installed sleeve block 204 is aligned and sleeved with the positioning rod 203 fixedly installed on the top surface of the placement plate 202. When the sleeve plate 210 is loosened, the sleeve plate 210 is pushed back to its original position under the elastic action of the spring 211. The connecting plate 209 pulls the push rod 207, so that the clamp 208 fixedly installed on the outer wall of the push rod 207 engages with the outer wall of the positioning rod 203 and presses the sleeve block 204 to quickly install the counter 102. This structure can quickly install the counter 102 and the valve body 100, making it easier for operators to maintain.

[0045] Example 3

[0046] Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below:

[0047] The limiting unit 300 includes a threaded rod 302 sleeved inside the upright 201. A sliding plate 303 is rotatably connected to the end of the threaded rod 302. A limit rod 304 is slidably provided inside the sliding plate 303. A locking block 305 is fixedly installed on the side of the sliding plate 303 away from the threaded rod 302. A locking tooth 301 is provided on the side of the locking block 305 away from the sliding plate 303.

[0048] The outer wall of the locking tooth 301 is fixedly installed on the outer wall of the handwheel 101. The locking teeth 301 are distributed around the center of the handwheel 101. Under the locking and restraint of the locking block 305 and the locking teeth 301, the handwheel 101 can be prevented from continuing to rotate.

[0049] The threaded rod 302 is threaded onto the outer wall of the upright 201, and the end of the limiting rod 304 is fixedly installed on the outer wall of the upright 201. Under the sliding restriction of the sliding plate 303 and the limiting rod 304, the rotating threaded rod 302 can push the sliding plate 303 rotatably connected to its end.

[0050] When in use, after the handwheel 101 has finished rotating, it needs to be restricted to prevent it from continuing to rotate. At this time, rotate the threaded rod 302. Since the end of the limit rod 304 is fixedly installed on the outer wall of the upright 201, and the slide plate 303 is slidably set with the limit rod 304, under its restriction, the rotating threaded rod 302 pushes the slide plate 303 rotatably connected to its end, so that the slide plate 303 drives the locking block 305 to engage with the locking teeth 301 fixedly installed on the outer wall of the handwheel 101, thereby restricting the rotation of the handwheel 101 to prevent leakage of the internal medium of the valve body 100.

[0051] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0052] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
