Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of valve, especially a water valve. BACKGROUND

[0002] Water valves are usually arranged in waterway systems to control the opening and closing of the waterway. A water valve comprises a handle, a valve core and a water channel shell. The water channel shell has two open ends to expose the water inlet and outlet at both ends of the valve seat. The water channel shell has a mounting hole on the side, and the valve seat is arranged opposite to the mounting hole. The valve core is installed in the water channel shell from the mounting hole and cooperates with the valve seat. The handle drives the valve core to rotate to change the waterway between the valve core and the valve seat, so that the water inlet and outlet are connected or separated to achieve the purpose of opening or closing the valve.

[0003] A water valve is provided. The valve seat is integrally arranged with the water channel shell, and the valve core is installed in the water channel shell from the mounting hole during assembly of the water valve. The water channel shell is provided with internal threads at the mounting hole. The valve core is limited in the water channel shell by arranging a threaded part above the valve seat to cooperate with the internal threads at the mounting hole. Although this arrangement facilitates the installation of the valve core, the cost of the valve seat is relatively high. During use of the water valve, repeated rotation of the handle may damage the thread cooperation between the threaded part and the water channel shell, thereby affecting the cooperation between the valve core and the water channel shell, causing the valve core to loosen, and affecting the stability of the water valve as a whole.

[0004] To reduce the cost of the valve seat, some water valves in related technologies use a split arrangement of the valve seat and the water channel shell. The water channel shell is provided with a threaded pipe. The water valve is connected to a designated position through the threaded pipe. One end of the threaded pipe inserted into the water channel shell abuts against the valve seat to limit the valve seat and prevent the valve seat and the valve core from deviating. However, the threaded pipe needs to be rotated to connect to the designated position. Rotation of the threaded pipe may cause loosening of the thread cooperation between the threaded pipe and the water channel shell, resulting in loosening of the valve seat and the valve core and deviation of the valve seat and the valve core, which is not conducive to the installation and use of the water valve.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In the water valve, the handle assembly connected to the valve core drives the valve core to rotate relative to the valve seat, thereby opening or cutting off the water flow valve path of the valve seat, so that the water flow can flow from the water inlet to the water outlet or stop flowing from the water inlet to the water outlet. When assembling the water valve, first, the valve seat is inserted into the water channel shell, then the valve core is installed into the water channel shell from the mounting hole, and the valve core is fixedly connected with the valve seat. Then, the limiting gland is installed into the water channel shell and abuts against the end portion of the valve seat to limit the valve seat in the axial direction. The mounting hole is formed on the circumferential side of the water channel shell. The limiting of the valve core through the mounting hole limits the valve seat in the circumferential and axial directions within the water channel shell, realizes the assembly of the valve core, the valve seat and the water channel shell, and is convenient and simple to install. The valve seat has low setting cost, and the valve core is not easy to loosen during repeated rotation of the handle assembly. The overall stability of the water valve is good.

[0023] 4. The water channel shell is connected with a threaded connection pipe through the connecting base to connect the water valve with external pipelines or install the water valve at a designated position through the threaded connection pipe. The threaded connection pipe is connected with the connecting base through screwing connection, which has the advantages of convenient and quick connection and good water tightness.

[0024] 5. The inner diameter of the limiting gland is smaller than the outer diameter of the threaded connection pipe. Therefore, during the rotation of the threaded connection pipe into the connecting base, the limiting gland can limit the length of the threaded connection pipe inserted into the water channel shell, avoiding direct extrusion on the valve seat during the connection of the threaded connection pipe with the connecting base, which can cause displacement of the valve core or damage to the valve seat.

[0025] 6. The connecting base is connected with the water channel shell through the outer thread and the inner thread in the water channel shell to facilitate the fixed connection of the connecting base with the water channel shell.

[0026] 7、The valve core and the installation hole are gap-fitted, so that the valve core is installed into the installation hole, and a limiting ring is arranged outside the valve core to fill the gap between the valve core and the installation hole, so that the valve core and the installation hole are stably fitted, the valve core or the installation hole is not exposed, the whole water valve is more beautiful, and foreign matters are not easy to enter the valve core to affect the normal work of the water valve;

[0027] 8、The rotary cover of the handle assembly is arranged outside the limiting ring, so that when the handle assembly is fixedly connected to the valve core, the rotary cover limits the limiting ring outside, so that the limiting ring is not easy to fall off from the installation hole, and the whole structure of the water valve is more stable and reasonable;

[0028] 9、The valve core is connected with the rotary cover through the connection of the connecting column and the connecting groove on the rotary cover, at least one side of the connecting column is a flat surface, and the connecting groove is matched with the connecting column (namely, the inner wall of the connecting groove is attached to the outer periphery of the connecting column), so that the rotary cover is circumferentially limited by the flat side of the connecting column, the rotary cover is not easy to rotate relative to the connecting column, and the rotary cover can drive the valve core to rotate to open or close the water valve;

[0029] 10、The end of the limiting ring, which faces the rotary cover, is a frustoconical shape, so that the rotary cover is arranged outside the limiting ring, and the contact and abrasion between the rotary cover and the limiting ring when the rotary cover rotates can be reduced;

[0030] 11、The valve core and the valve seat are connected through bolts, so that the connection is convenient and fast, the connection strength is good, and the installation limitation is small;

[0031] 12、A plurality of support rib plates are arranged on the outer periphery of the valve seat, the support rib plates are matched with the inner cavity of the water channel shell, so that the valve seat is radially limited in the water channel shell, and the valve seat is more stably installed.

DETAILED DESCRIPTION

[0041] The utility model will be further explained in connection with the drawings.

[0042] The embodiment discloses a water valve 1000, referring to Figure 1 and Figure 2 , water valve 1000 includes water channel shell 100, valve seat 200, valve core 300, limiting gland 900 and handle assembly 400, valve core 300 and valve seat 200 are arranged in water channel shell 100, limiting gland 900 is detachably arranged in water channel shell 100, handle assembly 400 is arranged outside water channel shell 100 and is fixedly connected to valve core 300.

[0043] Referring to Figure 2 , water channel shell 100 is tubular housing, specifically in the embodiment, water channel shell 100 is three-way, and it includes straight pipe 110 and branch pipe 120 connected perpendicularly to the lateral side of straight pipe 110.Valve seat 200 is detachably and coaxially arranged in straight pipe 110 of water channel shell 100, limiting gland 900 is detachably installed in straight pipe 110, limiting gland 900 is coaxially arranged with straight pipe 110, and limiting gland 900 abuts to one end of valve seat 200.

[0044] The inner cavity of the branch pipe 120 forms a mounting hole 121 which is formed on the peripheral side of the water channel shell 100, the valve core 300 is arranged in the mounting hole 121 and is connected to the mounting hole 121 in a circumferential rotating manner, the valve core 300 penetrates the mounting hole 121 and is fixedly connected with the valve seat 200. By rotating the valve core 300 relative to the valve seat 200 through the handle assembly 400 connected to the valve core 300, the flow path between the valve core 300 and the valve seat 200 can be changed, so as to open or close the water valve 1000.

[0045] In the embodiment, when assembling the water valve 1000, the valve seat 200 is first arranged in the straight pipe 110 of the water channel shell 100, then the valve core 300 is arranged in the branch pipe 120 of the water channel shell 100 from the mounting hole 121, and the valve core 300 is fixed with the valve seat 200, and then the limiting gland 900 is arranged in the straight pipe 110 and abuts against the end of the valve seat 200 to limit the valve seat 200 in the axial direction. Thus, the valve core 300 is limited through the mounting hole 121, and the valve seat 200 is limited in the axial direction through the limiting gland 900, so that the valve seat 200 is limited in the circumferential and axial directions in the water channel shell 100, the assembly of the valve core 300, the valve seat 200 and the water channel shell 100 is realized, and the assembly is convenient and simple. Moreover, when other pipe fittings are connected to the water valve 1000, the cooperation between the valve seat 200, the valve core 300 and the water channel shell 100 is not affected, so that the overall stability of the water valve 1000 is better.

[0046] Since the valve seat 200 and the water channel shell 100 are arranged separately, the valve seat 200 and the water channel shell 100 can be formed separately, the structural complexity of the valve seat 200 and the water channel shell 100 is reduced, the manufacturing cost of the valve seat 200 is reduced, and the valve core 300 is not easy to loosen during repeated rotation of the handle assembly 400, and the overall stability of the water valve 1000 is good.

[0047] Specifically, in the embodiment, the water channel shell 100 is a metal pipe fitting, and the valve seat 200 is an injection molding part, which are made of different processes and materials; the valve seat 200 is an injection molding part, which has a more mature and reliable manufacturing process, good water tightness of finished product and high yield. In addition, in other embodiments, both can also be metal parts or injection molding parts.

[0048] Referring to Figures 3 to 5, the valve seat 200 is approximately cylindrical in shape to be stably installed in the waterway housing 100. The valve seat 200 is provided with a water inlet 210 and a water outlet 220 at two ends thereof respectively, and the water inlet 210 and the water outlet 220 are correspondingly arranged at two ends of the straight pipe 110 of the waterway housing 100 to be connected with external pipes. The valve seat 200 is provided with a water flow valve path connecting the water inlet 210 and the water outlet 220, and the handle assembly 400 can drive the valve core 300 to rotate to open or cut off the water flow valve path, so that water flow can flow from the water inlet 210 to the water outlet 220 or stop flowing from the water inlet 210 to the water outlet 220, to realize the opening or closing of the water valve 1000. Specifically, referring to Figures 4 to 6 , the water flow valve path includes a water inlet flow path 230 and a water outlet flow path 240, one end of the water inlet flow path 230 is connected to the water inlet 210, and the other end of the water inlet flow path 230 away from the water inlet 210 penetrates the peripheral side of the valve seat 200 to form a first valve hole 250. One end of the water outlet flow path 240 is connected to the water outlet 220, and the other end of the water outlet flow path 240 away from the water outlet 220 penetrates the peripheral side of the valve seat 200 to form a second valve hole 260. Among them, the first valve hole 250 and the second valve hole 260 are both aligned with the valve core 300. The valve core 300 is provided with a through-flow water hole 310, which is initially aligned with the second valve hole 260, and the through-flow water hole 310 is only connected with the second valve hole 260 at this time, and the water valve 1000 is in a closed state. When the valve core 300 rotates, the through-flow water hole 310 can be aligned with the first valve hole 250 and the second valve hole 260 at the same time while the valve core 300 rotates, so as to connect the water inlet flow path 230 and the water outlet flow path 240, at this time, the water valve 1000 is in an open state.

[0049] In this embodiment, the second valve hole 260 is a long strip-shaped hole, and the first valve hole 250 is arranged at the side of the second valve hole 260. The through-flow water hole 310 is a long strip-shaped hole with the same shape and size as the second valve hole 260. When the valve core 300 is rotated to the second valve hole 260 completely opposite to the through-flow water hole 310, the first valve hole 250 is blocked from the through-flow water hole 310, that is, the water inlet flow path 230 is blocked from the water outlet flow path 240. When the valve core 300 is rotated to partially misalign the through-flow water hole 310 with the second valve hole 260, the through-flow water hole 310 can simultaneously connect the first valve hole 250 and the second valve hole 260, realizing the connection of the water inlet flow path 230 and the water outlet flow path 240.

[0050] Preferably, in some embodiments, the water inlet flow path 230 is provided with two, and two water inlet openings 210 and two first valve holes 250 are provided on the valve seat 200 correspondingly. The two first valve holes 250 are respectively arranged on two sides of the second valve hole 260, and different water flows (such as hot water and cold water respectively) can flow into the two water inlet flow paths 230 through the two water inlet openings 210, so that when the valve core 300 is rotated, the convergence adjustment of the two water flows can be realized (such as adjusting the cold and hot water volume to adjust the water temperature in the kitchen, bathroom, etc.). Of course, in other embodiments, the number of water inlet flow paths 230 can also be other values.

[0051] In this embodiment, the water path of the water valve 1000 is only provided on the valve seat 200 and the valve core 300, so that only the water tightness of the valve core 300 connected to the valve seat 200 needs to be ensured, and the water channel housing 100 only plays a surrounding and decorative role, without considering the water tightness of the water channel housing 100, thereby reducing the water tightness cost of the water valve 1000.

[0052] Preferably, a sealing ring is arranged around the first valve hole 250 and the second valve hole 260, and the valve core 300 is pressed against the sealing ring after being fixed to the valve seat 200, so as to enhance the water tightness between the valve seat 200 and the valve core 300.

[0053] Referring to Figure 3 , the outer periphery of the valve seat 200 is arranged with a plurality of support ribs 270, the support ribs 270 are circular, and the support ribs 270 are fitted to the inner cavity of the straight pipe 110 (that is, the outer periphery of the support ribs 270 is fitted to the inner cavity of the straight pipe 110). The inner cavity of the water channel housing 100 is through the support ribs 270, so that the valve seat 200 is radially limited in the water channel housing 100, the shaking of the valve seat 200 in the straight pipe 110 is reduced, and the valve seat 200 is installed more stably.

[0054] Referring to Figure 1 and Figure 2 , the end of the valve seat 200 away from the limiting gland 900 is provided with a step 290, and the end of the straight pipe 110 away from the limiting gland 900 is fixedly provided with a mounting ring portion 130 coaxially. When the valve seat 200 is installed in the straight pipe 110, the step 290 cooperates with the mounting ring portion 130 in the straight pipe 110 to limit the valve seat 200 in the axial direction, so that the valve seat 200 is limited in the axial direction between the limiting gland 900 and the mounting ring portion 130, and the valve seat 200 is installed more stably.

[0055] Referring to Figure 1 and Figure 2In the embodiment, the inner wall of one end of the straight pipe 110 close to the threaded connecting pipe 700 is provided with internal threads, and the outer periphery of the limiting gland 900 is provided with external threads. The limiting gland 900 is screwed to the straight pipe 110, so as to facilitate the connection and disassembly of the limiting gland 900 and the straight pipe 110, and the threaded connection also facilitates the adjustment of the position of the limiting gland 900 in the straight pipe 110.

[0056] The threaded connecting pipe 700 is connected to the straight pipe 110 along the axial direction of the straight pipe 110, and is used to install the water valve 1000 at a designated position. The threaded connecting pipe 700 is arranged opposite to the water inlet 210 of the valve seat 200.

[0057] In the embodiment, a connecting base 800 is fixedly arranged in the straight pipe 110, and the connecting base 800 is arranged at one end of the valve seat 200 away from the threaded connecting pipe 700. The connecting base 800 is annular, and the outer side of the connecting base 800 is fixed to the inner wall of the straight pipe 110.

[0058] The inner ring of the connecting base 800 is provided with internal threads, and the outer periphery of the threaded connecting pipe 700 is provided with external threads. The threaded connecting pipe 700 is screwed to the connecting base 800, so as to facilitate the connection and disassembly of the threaded connecting pipe 700 and the straight pipe 110.

[0059] Preferably, the threaded connecting pipe 700 is made of metal, so as to facilitate the turning of external threads on the surface of the threaded connecting pipe 700, and to enhance the strength of the threaded connecting pipe 700. In other embodiments, the threaded connecting pipe 700 can also be made of other suitable hard materials.

[0060] In the embodiment, the outer periphery of the threaded connecting pipe 700 is covered with external threads, so that the threaded connecting pipe 700 can be rotated to adjust the depth of insertion into the base 800. In other embodiments, the external threads on the threaded connecting pipe 700 can also be arranged only on the outer periphery of one end of the threaded connecting pipe 700 close to the straight pipe 110.

[0061] In the embodiment, the limiting gland 900 is annular and coaxially fixedly arranged in the straight pipe 110. The limiting gland 900 is arranged at one end of the connecting base 800 close to the valve seat 200, and the inner diameter of the limiting gland 900 is smaller than the outer diameter of the threaded connecting pipe 700.

[0062] In the prior art, the water valve 1000 is not provided with a limiting gland 900. When a user installs the water valve 1000 by himself, the user manually rotates the threaded connecting pipe 700 into the connecting base 800 and abuts against the valve seat 200, so as to install the water valve 1000 at a set position such as a washstand by the threaded connecting pipe 700. In the process of installing the water valve 1000, the threaded connecting pipe 700 needs to be rotated to be connected to the connecting member at the set position. In this process, the threaded connecting pipe 700 and the connecting base 800 are also rotated, which causes the threaded connection between the threaded connecting pipe 700 and the connecting base 800 to be loose, thereby causing the limiting of the valve seat 200 and the valve core 300 to be loose, and the stability of the water valve 1000 as a whole to be poor. Moreover, if the threaded connecting pipe 700 is inserted into the water channel shell 100 too deeply, the threaded connecting pipe 700 will abut against the valve seat 200 in the water channel shell 100, and the threaded pipe 700 is likely to press the valve seat 200, causing the valve seat 200 to be damaged or deviated.

[0063] In the embodiment, the inner diameter of the limiting gland 900 is smaller than the outer diameter of the threaded connecting pipe 700, so that the limiting gland 900 can block the movement path of the threaded connecting pipe 700, limit the length of the threaded connecting pipe 700 extending into the water channel shell 100, and avoid directly pressing the valve seat 200 in the process of connecting the threaded connecting pipe 700 and the connecting base 800, thereby causing the valve seat 200 and the valve core 300 to be deviated or the valve seat 200 to be damaged. When the threaded connection between the threaded connecting pipe 700 and the connecting base 800 is loose, the limiting gland 900 still axially limits the valve seat 200, so that the valve seat 200 will not be deviated, and the stability of the water valve 1000 as a whole is better. In the embodiment, the outer periphery of the connecting base 800 is provided with external threads, and the connecting base 800 is threadedly connected to the internal threads of the straight pipe 110, so as to facilitate the fixed connection between the connecting base 800 and the water channel shell 100.

[0064] In the embodiment, the position of the limiting gland 900 in the straight pipe 110 is adjusted by rotation, so as to adjust the length of the threaded connecting pipe 700 extending into the straight pipe 110 of the water channel shell 100, and adapt to the use requirements of the threaded connecting pipe 700 in different installation environments. In addition, in other embodiments, the limiting gland 900 and the connecting base 800 can also be connected to the water channel shell 100 in other suitable manners such as clamping and one-piece forming.

[0065] Reference Figure 2The abutment ring 910 is coaxially and oppositely arranged with the threaded connecting pipe 700. The outer diameter of the abutment ring 910 is smaller than the inner diameter of the straight pipe 110, and a gap is formed between the outer periphery of the abutment ring 910 and the inner wall of the straight pipe 110. The inner diameter of the abutment ring 910 is smaller than the outer diameter of the threaded connecting pipe 700, so that after the threaded connecting pipe 700 is screwed with the connecting base 800, the end face of the threaded connecting pipe 700 inserted into the straight pipe 110 abuts against the abutment ring 910.

[0066] The outer shape of the abutment ring 910 is a prism with a polygonal bottom surface. In this embodiment, the outer shape of the abutment ring 910 is a hexagonal prism, and the projection of the outer periphery of the abutment ring 910 on the limiting gland 900 is a regular hexagon. Therefore, when the limiting gland 900 is installed, a hexagonal wrench can be used to drive the limiting gland 900 to rotate and be screwed with the inner wall of the straight pipe 110.

[0067] Referring to Figure 2 and Figure 6 The valve core 300 is coaxially arranged in the mounting hole 121 of the branch pipe 120. In this embodiment, the valve core 300 is fixedly provided with a mounting bracket 320 on the outer periphery, and a plurality of connecting holes 321 are formed in the mounting bracket 320. The valve seat 200 is provided with threaded holes 280 aligned with the connecting holes 321, and a bolt 600 is arranged in the aligned connecting holes 321 and threaded holes 280. The bolt 600 is screwed with the threaded holes 280 to fixedly connect the valve core 300 and the valve seat 200, so that the valve core 300 and the valve seat 200 are connected conveniently and quickly, have good connection strength, and the valve core 300 is less limited during installation.

[0068] In addition, in other embodiments, the valve core 300 and the valve seat 200 can also be connected by clamping, inserting or other suitable methods.

[0069] In this embodiment, the valve core 300 is gap-fitted with the mounting hole 121 to facilitate the installation of the valve core 300 in the mounting hole 121. In addition, in other embodiments, the outer periphery of the valve core 300 can also be attached to the inner wall of the mounting hole 121.

[0070] Referring to Figure 2 and Figure 3In the embodiment, the valve core 300 is externally provided with a limiting ring 500, the outer periphery of the limiting ring 500 is attached to the inner wall of the mounting hole 121, and the inner ring of the limiting ring 500 is attached to the outer periphery of the valve core 300. The gap between the valve core 300 and the mounting hole 121 is filled by the limiting ring 500, so that the valve core 300 cooperates with the mounting hole 121 stably, while avoiding exposure of the valve core 300 or the mounting hole 121, so that the overall water valve 1000 is more beautiful, and foreign matters are not easy to enter the valve core 300 to affect the normal work of the water valve 1000.

[0071] In the embodiment, the limiting ring 500 can be fixed in the mounting hole 121 by interference fit, or the limiting ring 500 and the branch pipe 120 can be clamped by a clamping structure.

[0072] With reference to Figure 2 and Figure 3 , the handle assembly 400 includes a rotating cover 410, which is fixedly connected to the valve core 300 and coaxially arranged with the valve core 300, so that rotating the rotating cover 410 can drive the valve core 300 to rotate to open or close the water valve 1000.

[0073] The rotating cover 410 is arranged at one end of the limiting ring 500 away from the water channel housing 100 and covers the outside of the limiting ring 500. The outer diameter of the rotating cover 410 is greater than the outer diameter of the limiting ring 500, so that when the handle assembly 400 is fixedly connected to the valve core 300, the rotating cover 410 limits the limiting ring 500 on the outside, so that the limiting ring 500 is not easy to fall off from the mounting hole 121, and the overall structure of the water valve 1000 is more stable and reasonable.

[0074] The rotating cover 410 is connected to a lever 420 on the circumferential side, and the lever 420 extends in the radial direction of the rotating cover 410. The lever 420 can increase the moment arm when the user rotates the handle assembly 400, facilitating rotation of the handle assembly 400 and the valve core 300.

[0075] The end of the limiting ring 500 facing the rotating cover 410 is in the shape of a truncated cone, so as to facilitate covering of the rotating cover 410 outside the limiting ring 500, while reducing the contact wear between the rotating cover 410 and the limiting ring 500 when the rotating cover 410 rotates.

[0076] With reference to Figure 2 and 7 , in the embodiment, a circle of stepped grooves 330 is circumferentially arranged at the end of the valve core 300 away from the valve seat 200, and the inner ring of the limiting ring 500 is fitted in the stepped grooves 330, so that the limiting ring 500 not only limits the valve core 300 in the radial direction of the mounting hole 121, but also limits the displacement of the valve core 300 in the axial direction of the mounting hole 121, so that the overall structure of the water valve 1000 is more stable and reliable.

[0077] The valve core 300 is provided with a connecting column 340 on the side away from the valve seat 200, and the rotating cover 410 is provided with a connecting groove 411 matched with the connecting column 340 on the side facing the valve core 300, and the rotating cover 410 is connected to the valve core 300 through the plug-in cooperation of the connecting column 340 and the connecting groove 411.

[0078] At least one side of the connecting column 340 is a flat surface, the connecting groove 411 is matched with the connecting column 340 (i.e. the inner wall of the connecting groove 411 is attached to the outer periphery of the connecting column 340), and the flat side of the connecting column 340 limits the rotation of the rotating cover 410 in the circumferential direction, so that the rotating cover 410 can drive the valve core 300 to rotate to open or close the water valve 1000. Specifically, in the embodiment, the connecting column 340 is in the shape of a cuboid, and all four sides are flat surfaces. Correspondingly, the connecting groove 411 is a rectangular groove.

[0079] The assembly steps of the water valve 1000 of the embodiment are as follows:

[0080] When assembling the water valve 1000, first, the valve seat 200 is assembled into the straight pipe 110, so that the step 290 abuts against the mounting ring 130. Then, the valve core 300 is inserted into the mounting hole 121, the valve core 300 is fixed to the valve seat 200 by the bolt 600, and the limiting ring 500 is inserted into the mounting hole 121 to be sleeved on the valve core 300, thereby limiting the valve core 300 and the valve seat 200 in the circumferential direction, so that the valve seat 200 is not easy to rotate relative to the straight pipe 110. Then, the limiting gland 900 can be installed first. Since the valve seat 200 is limited in the circumferential direction, the limiting gland 900 is not easy to drive the valve seat 200 to rotate in the circumferential direction when being rotated and installed, which facilitates the installation of the limiting gland 900. After the limiting gland 900 is installed, the connecting base 800 is screwed to the straight pipe, and the threaded connecting pipe 700 is connected to the connecting base 800. Alternatively, the handle assembly 400 can be installed first after the limiting ring 500 is installed, and then the limiting gland 900 is installed.

[0081] The above is only a preferred embodiment of the present application, so equivalent changes or modifications made according to the structure, features and principles described in the patent application range of the present application are included in the patent application range of the present application.
