Description

Technical Field

[0001] This utility model relates to the field of fluid control valve technology, and in particular to an angle valve whose on / off status is easily identifiable, suitable for fluid pipeline control in household, industrial and other applications. Background Technology

[0002] Existing angle valves generally have the switch markings printed on the top surface of the handwheel sleeve. When the handwheel sleeve rotates, the markings rotate with it, making it impossible for users to intuitively determine the current switch status. Furthermore, the markings are prone to wear and tear after prolonged use, leading to a high risk of misoperation.

[0003] This invention solves the problem of markings rotating and being difficult to identify by setting a fixed cover that remains static relative to the valve body and various indicator structures. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an angle valve whose on / off status is easily identifiable. By setting a fixed cover with an marking on it, the valve remains static and visible from the front during the operation of the handwheel sleeve. Users can intuitively and clearly judge the on / off status of the angle valve. The fixed cover is connected to the valve body through an axial locking mechanism. The locking mechanism completes locking and circumferential positioning simultaneously within a single axial stroke. When assembling the fixed cover, it only needs to be pressed in once for automatic alignment without additional tightening operations, thus improving the convenience and safety of operation and use.

[0005] The purpose of this utility model is achieved as follows:

[0006] An angle valve with easily identifiable on / off status includes a valve body having a fluid passage; a valve core rod rotatably disposed within the valve body and controlling fluid flow; a handwheel sleeve rotating synchronously with the valve core rod and having an indicator structure on its top; and a fixed cover located inside the handwheel sleeve and remaining static relative to the valve body, the fixed cover having a static indicator; the fixed cover is connected to the valve body via an axial locking mechanism, the locking mechanism simultaneously completing locking and circumferential positioning within a single axial stroke; and a single press simultaneously achieves initial angular alignment between the static indicator and the indicator structure; the indicator structure and the static indicator display the on / off status through relative positional changes, the static indicator being located in a ring area directly visible to the user's standing line of sight. In the above angle valve, the axial locking mechanism includes a fixed seat, one end of which is directly or indirectly connected to the valve body, and the other end having at least two fixed posts, the top of which has a locking platform; the inner wall of the fixed cover has a locking groove, the locking groove axially engaging with the locking platform, keeping the fixed cover static.

[0007] In the aforementioned angle valve, the locking platform is a radial shoulder. During assembly, the fixing cover is pressed in from top to bottom, and the locking groove engages with the radial shoulder to form an axial anti-disengagement structure.

[0008] In the aforementioned angle valve, the fixing posts are evenly distributed circumferentially and form two-point or three-point engagement with the slot.

[0009] In the aforementioned angle valve, the inner wall of the handwheel sleeve is provided with radial ribs, and a clearance groove is formed between the radial ribs. The locking platform passes through the clearance groove and is axially locked with the locking groove.

[0010] The aforementioned angle valve also includes a valve core sleeve, which is fixed to the valve body and radially positions the valve core assembly.

[0011] In the aforementioned angle valve, the fixed seat is directly connected to the valve body via a detachable connection structure, or the fixed seat is connected to the valve core sleeve via a detachable connection structure, and the valve core sleeve is connected to the valve body; the detachable connection structure includes a threaded connection or a snap-fit ​​connection.

[0012] In the aforementioned angle valve, the top of the handwheel sleeve is integrally or separately fixedly connected with a top cover, and the indicating structure is located on the top cover.

[0013] In the aforementioned angle valve, when the indicator structure is a perforated window, the perforated window is opened on the top cover and faces the static indicator; as the top cover rotates, the perforated window selectively exposes different areas corresponding to the static indicator to display the on / off status and water volume.

[0014] In the aforementioned angle valve, when the indicating structure is a pointer, the pointer is formed by a solid or hollowed-out rib that is radially opened on the top cover; the static indicator is located on the outer end face of the fixed cover; the tip of the pointer points to different areas of the static indicator during rotation to indicate the on / off state and water volume.

[0015] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0016] 1. The static sign of this utility model does not rotate with the handwheel sleeve, and can be read by the user while standing, solving the problem of traditional handwheel signs being difficult to read when they rotate;

[0017] 2. The fixed cover of this utility model is connected to the valve body through an axial locking mechanism. The locking mechanism completes locking and circumferential positioning simultaneously within a single axial stroke. Moreover, a single press-in simultaneously achieves the initial relative angle alignment of the static mark and the indicator structure, which not only improves assembly efficiency but also eliminates the deviation caused by multiple rotations for threaded installation.

[0018] 3. The mounting bracket of this utility model adopts a snap-fit ​​or threaded connection, which can be compatible with the needs of different diameters and structures, and has a wide range of applications;

[0019] 4. The indicator structure of this utility model can be set in the handwheel sleeve or the top cover and comes in various forms, which expands the design freedom and is compatible with the appearance requirements of different users. Attached Figure Description

[0036] The present invention will be further described below with reference to specific embodiments:

[0037] like Figure 1-16 As shown, an angle valve with easily identifiable on / off status includes a valve body 1, which has a fluid passage; a valve core rod 3, rotatably disposed within the valve body 1 and controlling the flow of fluid; a handwheel sleeve 7, which rotates synchronously with the valve core rod 3 and has an indicator structure 41 on its top; and a fixed cover 5, located inside the handwheel sleeve 7 and remaining static relative to the valve body 1, with a static indicator 51 on the fixed cover 5; the fixed cover 5 is connected to the valve body 1 via an axial locking mechanism, which simultaneously locks and positions circumferentially within a single axial stroke; and a single press simultaneously achieves the initial relative angular alignment of the static indicator 51 and the indicator structure 41; the indicator structure 41 and the static indicator 51 indicate the on / off status through changes in their relative positions, with the static indicator 51 located in a ring area directly visible to the user while standing. In this technical solution, the static indicator 51 does not rotate with the handwheel, solving the problem of traditional handwheel indicators being difficult to identify when rotating. Users can read it while standing, reducing the risk of misoperation. In addition, the fixed cover is connected to the valve body through an axial locking mechanism. The locking mechanism completes locking and circumferential positioning simultaneously within a single axial stroke. Moreover, a single press-in simultaneously achieves the initial relative angle alignment between the static indicator and the indicator structure, resulting in high assembly efficiency while also eliminating the deviation caused by multiple rotations during threaded installation.

[0038] As a first option, the axial locking mechanism includes a fixed base 6, one end of which is directly or indirectly connected to the valve body 1, and the other end is provided with at least two fixed posts 61. Each fixed post 61 has a locking platform 62 at its top. The inner wall of the fixed cover 5 is provided with a locking groove 52, which axially engages with the locking platform 62, keeping the fixed cover 5 static. In this technical solution, the locking platform 62 and the locking groove 52 are axially engaged, eliminating the need for screws and allowing for quick assembly.

[0039] As the first choice, such as Figure 1 , Figure 2 As shown, the indicator structure 41 is an arrow or triangle located at the top edge of the handwheel sleeve 7, pointing to the static mark 51 located on its inner ring.

[0040] As a first option, the locking platform 62 has a radial shoulder. During assembly, the fixing cover 5 is pressed in from top to bottom, and the locking groove 52 engages with the radial shoulder to form an axial anti-disengagement structure. The fixing posts 61 are evenly distributed circumferentially, forming two-point or three-point engagement with the locking groove 52. In this technical solution, locking can be completed by pressing in once during assembly, simplifying the production line process.

[0041] In the aforementioned angle valves, such as Figure 7 As shown, the inner wall of the handwheel sleeve 7 is provided with radial ribs 71a, and a clearance groove 61a is formed between the radial ribs 71a. The locking platform 62 passes through the clearance groove 61a and is axially engaged with the locking groove 52. The structure of this technical solution is reasonable and highly practical.

[0042] The aforementioned angle valve also includes a valve core sleeve 2, which is fixed inside the valve body 1 and radially positions the valve core assembly 21. The fixing seat 6 is directly connected to the valve body 1 via a detachable connection structure, or the fixing seat 6 is connected to the valve core sleeve 2 via a detachable connection structure, with the valve core sleeve 2 connected to the valve body 1. The detachable connection structure includes either a threaded connection or a snap-fit ​​connection. (Threaded connection connection) Figure 15 , Figure 16 As shown in the diagram, the snap-fit ​​connection is not shown. In this technical solution, the mounting of the fixing seat 6 adopts a threaded or snap-fit ​​connection, which can be compatible with the needs of different diameters and structures and has a wide range of applications. For example, the fixing seat 6 is threadedly connected to the valve core sleeve 2, which is compatible with small diameter installation, reduces the valve body processing length, and reduces mold costs; the fixing seat 6 is threadedly connected to the valve body 1, which is suitable for large diameter or high pressure scenarios, enhances axial sealing reliability, and expands the scope of application.

[0043] As a first option, the top of the handwheel sleeve 7 is integrally or separately fixedly connected to a top cover 4, and the indicator structure 41 is located on the top cover 4. The top cover 4 of the handwheel sleeve 7 can be either integral or separate, and the indicator structure 41 can be located on the handwheel sleeve or the top cover. In this technical solution, the design freedom is expanded, and different appearance requirements are compatible.

[0044] In the aforementioned angle valves, such as Figure 9 -- Figure 11 As shown, when the indicator structure 41 is a cutout window, the cutout window is opened on the top cover 4 and faces the static indicator 51; when the top cover 4 rotates, the cutout window selectively exposes different areas corresponding to the static indicator 51 to display the switch and water level status; wherein the top cover 4 body does not need to be transparent, and is only visible through the cutout window.

[0045] In the aforementioned angle valves, such as Figure 12 -- Figure 14As shown, when the indicating structure 41 is a pointer, the pointer is formed by a solid or hollow rib that is radially opened on the top cover 4; the static mark 51 is located at the outer end face of the fixed cover 5; the tip of the pointer points to different areas of the static mark 51 during rotation to indicate the switch status and water level status; wherein the pointer body does not need to cover the static mark 51 directly above it.

[0046] In this technical solution, the static identifier 51 is the word "on", "off", "ON" or "OFF" or a scale size, etc.

[0047] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
