Description

Technical Field

[0001] The present invention relates to the field of valve technology, and in particular to a multifunctional valve and a multifunctional valve assembly having the same. Background Art

[0002] The magnetic control valve is a locking valve that can prevent theft and is also called a lock valve. It is mainly used as the main control component in the water supply, heating and gas supply pipeline systems of residential buildings.

[0003] The existing magnetic control valve has a relatively simple function. When the magnetic control valve locks the handle, the valve is also in a closed state. This magnetic control valve cannot be used as a normal valve and cannot be used in situations where locking is sometimes required and sometimes not required. That is, the existing lock control valve cannot be freely switched between ordinary valves, magnetic control valves or mechanical lock valves, and its versatility is poor. Summary of the invention

[0004] Based on this, it is necessary to provide a multifunctional valve with good versatility and the ability to switch states freely, and a multifunctional valve assembly having the same, in order to address the above technical problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A multifunctional valve comprises a valve body, a handle and a valve stem unit, wherein the handle is rotatably mounted on the valve body, one end of the valve stem unit is mounted in the valve body, and the other end passes through the valve body and is connected to the handle, and the valve stem unit opens / closes the valve under the drive of the handle;

[0007] The multifunctional valve further comprises a magnetic unit, a magnetic fastener unit and / or a mechanical fastener, a mounting hole is provided on a side surface of the valve body close to the handle, one end of the magnetic unit is installed in the mounting hole, a connecting hole and a locking hole corresponding to the mounting hole are provided on the handle, and the connecting hole is communicated with the locking hole;

[0008] When the magnetic fastener unit is installed in the connecting hole, the end of the magnetic unit away from the valve body can extend out of the mounting hole and be inserted into the locking hole under the action of the magnetic fastener unit to lock the handle; or the end of the magnetic unit away from the valve body can be received in the mounting hole under the action of the magnetic fastener unit to release the lock of the handle;

[0009] When the mechanical fastener is installed in the connecting hole, one end of the mechanical fastener can pass through the locking hole and press the magnetic unit and simultaneously extend into the mounting hole to lock the handle; or one end of the mechanical fastener presses the magnetic unit into the mounting hole, and this end of the mechanical fastener is only located in the locking hole to unlock the handle.

[0010] In the present application, by setting the magnetic fastener unit and the mechanical fastener, during use, it is only necessary to selectively install the magnetic fastener unit and the mechanical fastener according to needs, so that the multifunctional valve can be freely switched between ordinary valves, magnetically controlled valves, and mechanical locking valves, thereby meeting the use of different occasions. The switching is not only simple and convenient but also highly versatile.

[0011] In one of the embodiments, the multifunctional valve further includes an identification unit, which is disposed between the handle and the magnetic fastening unit and is used to identify the attraction or repulsion state between the magnetic fastening unit and the magnetic unit.

[0012] In one of the embodiments, the magnetic fastener unit includes a fastener and a first magnet, the fastener is threadedly connected in the connecting hole; a first fixing hole is formed at one end of the fastener close to the valve body, and the first magnet is fixed in the first fixing hole.

[0013] In one embodiment, the magnetic fastener unit further includes a second magnetic steel, the second magnetic steel is disposed at an end of the fastener away from the first magnetic steel, and the magnetic pole of the second magnetic steel facing away from the end of the fastener is opposite to the magnetic pole of the first magnetic steel facing away from the end of the fastener. In one embodiment, the magnetic unit includes a third magnetic steel and an elastic member, the elastic member is received in the mounting hole, one end of the third magnetic steel abuts against the elastic member, and the other end can extend into the locking hole or be received in the mounting hole.

[0014] In one embodiment, the mechanical fastener includes a main body and a boss, the main body can be threadedly connected to the connecting hole, and one end of the boss can extend from the through hole into the locking hole to press the magnetic unit into the mounting hole, or the boss extends into the mounting hole.

[0015] When the boss presses the magnetic unit into the mounting hole, the handle can be contacted and locked; when the boss extends into the mounting hole, mechanical locking can be achieved. It can be understood that the magnetic control valve and the mechanical locking valve can be freely switched by controlling the mechanical fastener.

[0016] In one embodiment, an observation window is provided on the handle, and a third mark and a fourth mark are provided on the valve body. When the handle rotates relative to the valve body to control the valve body to open or close, the third mark or the fourth mark is located in the observation window.

[0020] It is understandable that by providing a protrusion to cooperate with the limiting groove, the handle is prevented from rotating at an excessive angle, thereby preventing the multifunctional valve from being over-closed, stuck, etc.

[0021] In one embodiment, an observation window is provided on the handle, and a third mark and a fourth mark are provided on the valve body. When the handle rotates relative to the valve body to control the valve body to open or close, the third mark or the fourth mark is located in the observation window.

[0026] Compared with the prior art, the multifunctional valve is provided with the magnetic fastener unit and the mechanical fastener. Therefore, during use, the multifunctional valve only needs to selectively install the magnetic fastener unit and the mechanical fastener according to needs, so as to realize the free switching of the multifunctional valve as an ordinary valve, a magnetically controlled valve, and a mechanical locking valve, thereby meeting the use in different occasions. The switching is not only simple and convenient but also highly versatile. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0039] like Figure 1 The present invention provides a multifunctional valve 100, which can be installed on a gas pipeline to control the on / off of the gas pipeline and prevent the gas pipeline from being maliciously connected. It is understandable that the multifunctional valve 100 can also be installed on other pipelines similar to gas, such as air conditioning pipelines, HVAC pipelines, etc.

[0040] Preferably, the multifunctional valve 100 may be a ball valve, or other gate valves except the ball valve. In this embodiment, the multifunctional valve 100 is a ball valve, and the ball valve is used as the object of explanation to specifically explain the structure and principle of the multifunctional valve 100.

[0041] Specifically, Figures 1 to 3 As shown, the multifunctional valve 100 comprises a valve body 10, a valve stem unit 20 and a handle 30. One end of the valve stem unit 20 is installed in the valve body 10, and the other end passes through the valve body 10. The handle 30 is rotatably installed on the valve body 10 and connected to the end of the valve stem unit 20 passing through the valve body 10. The handle 30 is rotated to drive the valve stem unit 20 to rotate, so as to realize the opening / closing of the multifunctional valve 100.

[0042] Furthermore, the multifunctional valve 100 further includes a magnetic unit 40, a magnetic fastener unit 50 and / or a mechanical fastener 60. A mounting hole 11 is provided on one side of the valve body 10 close to the handle 30, one end of the magnetic unit 40 is installed in the mounting hole 11, and a connecting hole 31 and a locking hole 32 corresponding to the mounting hole 11 are provided on the handle 30, and the connecting hole 31 is connected to the locking hole 32; when the magnetic fastener unit 50 is installed in the connecting hole 31, the end of the magnetic unit 40 away from the valve body 10 can extend out of the mounting hole 11 and be stuck in the locking hole 32 under the action of the magnetic fastener unit 50 to lock the handle 30, that is, to realize the function of the magnetically controlled valve; or the magnetic unit 40 is away from the valve body 10. One end of the body 10 can be received in the mounting hole 11 under the action of the magnetic fastener unit 50 to release the lock of the handle 30, that is, to realize the function of a common valve; and / or when the mechanical fastener 60 is installed in the connecting hole 31, one end of the mechanical fastener 60 can press the magnetic unit 40 into the locking hole 32 and extend into the mounting hole 11 at the same time to lock the handle 30, that is, to realize the function of a mechanical locking valve; or one end of the mechanical fastener 60 presses the magnetic unit 40 into the mounting hole 11 to release the lock of the handle 30, that is, to realize the function of a common valve.

[0043] It can be understood that by setting up the magnetic fastener unit 50 and / or the mechanical fastener 60, during use, it is only necessary to selectively install the magnetic fastener unit 50 and the mechanical fastener 60 according to needs, so that the multifunctional valve 100 can be freely switched between being an ordinary valve, a magnetically controlled valve, and a mechanical locking valve, thereby meeting the use of different occasions and sites and improving its versatility; at the same time, the switching between the functions of the multifunctional valve 100 is not only simple but also convenient.

[0044] The outer wall of the valve body 10 is provided with a matching portion 12, and the mounting hole 11 is located on the matching portion 12. The matching portion 12 is provided with a communicating hole (not shown), and the valve stem unit 20 passes through the communicating hole at one end away from the valve body 10, and the handle 30 is covered on the matching portion 12 and rotatably connected to the matching portion 12.

[0045] like Figure 6 As shown, the valve stem unit 20 includes a valve core 21 and a valve stem 22. The valve core 21 is installed in the valve body 10. One end of the valve stem 22 is fixedly connected to the valve core 21, and the other end passes through the connecting hole and is fixedly connected to the handle 30. The handle 30 is rotated to drive the valve stem 22 to rotate, so as to control the rotation of the valve core 21, thereby realizing the opening / closing of the multi-functional valve 100.

[0046] like Figure 5As shown, a protrusion 33 is formed on the inner side wall of the handle 30, and a limiting groove 13 is formed on one side of the valve body 10 where the mounting hole 11 is formed. The protrusion 33 cooperates with the limiting groove 13 to limit the rotation angle of the handle 30 relative to the valve body 10. Of course, in other embodiments, the positions of the protrusion 33 and the limiting groove 13 can be interchanged, as long as the limiting of the handle 30 can be achieved.

[0047] It is understandable that by providing the protrusion 33 and cooperating with the limiting groove 13, it is possible to prevent the handle 30 from rotating too much, thereby preventing the multifunctional valve 100 from being over-closed, stuck, etc.

[0048] Preferably, the limiting groove 13 is an arc groove, and its arc is 90 degrees, so as to cooperate with the 90-degree opening / closing of the multifunctional valve 100.

[0049] It can be understood that the two ends of the limit groove 13 are the limit positions of the movement of the handle 30, and the two limit positions respectively indicate the opening or closing of the multifunctional valve 100.

[0050] Furthermore, if Figure 2 As shown, an observation window 34 is provided on the handle 30, and a third mark 14 and a fourth mark 15 are provided on the valve body 10. When the handle 30 is rotated relative to the valve body 10 to control the valve body 10 to be opened or closed, the third mark 14 or the fourth mark 15 is located in the observation window 34. The user can intuitively obtain the open / closed state of the multifunctional valve 100 through the observation window 34, so as to facilitate the user's use and operation.

[0051] Preferably, an identification plate 16 is provided on the valve body 10 , and the identification plate 16 is accommodated in the handle 30 . The third identification 14 and the fourth identification 15 are arranged on the identification plate 16 at intervals.

[0052] Furthermore, the angle between the third mark 14 and the fourth mark 15 is equal to the rotation angle of the handle 30 relative to the valve body 10 to open or close. That is, it is ensured that when the handle 30 is rotated relative to the valve body 10 to open or close, it matches the third mark 14 or the fourth mark 15.

[0053] Optionally, the third mark 14 and the fourth mark 15 can be marked with different colors or different words, for example, the third mark 14 is red to indicate that the valve body 10 is in a closed state, and the fourth mark 15 is green to indicate that the valve body 10 is in an open state; or the third mark 14 is the word "off" to indicate that the valve body 10 is in a closed state, and the fourth mark 15 is the word "open" to indicate that the valve body 10 is in an open state; or the above two methods can be combined, and the words "open", "off" and the like can be written on the colored identification plate at the same time. It can be understood that the specific identification of the third mark 14 and the fourth mark 15 can be set according to the user's usage habits and needs, as long as it is convenient for the user to use and operate. In one embodiment, the number of magnetic units 40 and magnetic fastener units 50 is 1. When the magnetic unit 40 and the magnetic fastener unit 50 attract each other (i.e., the magnetic poles of the two ends of the magnetic unit 40 and the magnetic fastener unit 50 are the same), the magnetic unit 40 extends into the locking hole 32 under the action of the suction force to lock the handle 30, and the multifunctional valve 100 can be used as a magnetically controlled valve; when the magnetic fastener unit 50 and the corresponding magnetic unit 40 repel each other (i.e., the magnetic poles of the two ends of the magnetic unit 40 and the magnetic fastener unit 50 are opposite), the magnetic unit 40 withdraws from the locking hole 32 under the action of the repulsive force and is pressed into the mounting hole 11, that is, the lock of the handle 30 is contacted, and the multifunctional valve 100 can be used as an ordinary valve.

[0054] It can be understood that, in this embodiment, the multifunctional valve 100 can be switched between a common valve and a magnetically controlled valve by simply swapping the two ends of the magnetic fastener unit 50 according to needs during installation.

[0055] In another embodiment, the number of magnetic units 40 and magnetic fastener units 50 includes 2, and the number of mounting holes 11, connecting holes 31 and locking holes 32 respectively corresponds to the number of magnetic units 40; the magnetic poles of the magnetic units 40 in the two mounting holes 11 facing the same end are different; the magnetic poles of the magnetic fastener units 50 in the two connecting holes 31 facing the same end are different, and the magnetic fastener unit 50 in each connecting hole 31 can attract or repel each other with the magnetic unit 40 in the corresponding mounting hole 11.

[0056] When the magnetic fastener unit 50 and the corresponding magnetic unit 40 are attracted to each other, the magnetic unit 40 extends into the locking hole 32 under the action of the suction force to lock the handle 30, and the multifunctional valve 100 can be used as a magnetically controlled valve; when the magnetic fastener unit 50 and the corresponding magnetic unit 40 repel each other, the magnetic unit 40 withdraws from the locking hole 32 under the action of the repulsive force and is pressed into the mounting hole 11, that is, the lock of the handle 30 is contacted, and the multifunctional valve 100 can be used as an ordinary valve.

[0057] It can be understood that in this embodiment, the multifunctional valve 100 switches between the ordinary valve and the magnetic control valve by simply swapping the magnetic fastener unit 50 in the connection hole 31 so that the magnetic fastener unit 50 and the magnetic unit 40 in the corresponding mounting hole 11 can attract or repel each other. Not only is the switching convenient, simple and fast, but it can also adapt to different environments, improving its applicability.

[0058] In other embodiments, when the number of the magnetic units 40 and the magnetic fastener units 50 is 3 or more, the use process may refer to the case where the number of the two is one, or the case where the number of the two is 2, or may be mixed for other cases, which will not be described in detail here.

[0059] In this embodiment, the number of the magnetic unit 40 and the magnetic fastener unit 50 may be two. When the function of the multifunctional valve 100 is switched, the two magnetic fastener units 50 can be swapped.

[0060] like Figures 4 to 6 As shown, the magnetic unit 40 includes a third magnet 41 and an elastic member 42. The elastic member 42 is accommodated in the mounting hole 11. One end of the third magnet 41 abuts against the elastic member 42, and the other end can extend into the locking hole 32 or be accommodated in the mounting hole 11 under the action of the magnetic fastener unit 50 or the mechanical fastener 60.

[0061] Preferably, the third magnetic steel 41 is a strong magnet, and the elastic member 42 is a spring or a component with elastic function.

[0062] See also Figure 2 , the magnetic fastener unit 50 includes a fastener 51 and a first magnet 52, the fastener 51 is threadedly connected in the connecting hole 31; a first fixing hole 511 is opened at one end of the fastener 51 close to the valve body 10, and the first magnet 52 is fixed in the first fixing hole 511. The first magnet 52 and the third magnet 41 are attracted or repelled. It can be understood that the attraction between the first magnet 52 and the third magnet 41 can be that the two ends of the first magnet 52 and the third magnet 42 facing each other, one of which is the N pole and the other is the S pole; the repulsion between the first magnet 52 and the third magnet 41 can be that the two ends of the first magnet 52 and the third magnet 42 facing each other are both N poles or both S poles. The above situation can be selected according to specific installation requirements.

[0063] Preferably, the shape of the fastener 51 matches the shape of the connecting hole 31, so that the fastener 51 can be installed in the connecting hole 31. In this embodiment, the fastener 51 is cylindrical, and the connecting hole 31 is a cylindrical hole.

[0064] Preferably, the outer peripheral wall of the fastener 51 has threads, and the hole wall of the connecting hole 31 also has threads, and the fastener 51 is threadedly connected to the inner wall of the connecting hole 31, thereby achieving the installation of the fastener 51.

[0065] The first magnetic steel 52 is a magnetic steel, and the magnetic force of the first magnetic steel 52 is greater than the magnetic force of the third magnetic steel 41. It is understandable that the magnetic force of the first magnetic steel 52 is greater than the magnetic force of the third magnetic steel 41, which can ensure that after the magnetic fastener unit 50 is installed, there is sufficient magnetic force to attract or repel the third magnetic steel 41.

[0066] Preferably, the diameter of the first magnetic steel 52 is greater than the diameter of the third magnetic steel 41 , thereby ensuring that the magnetic force of the first magnetic steel 51 is greater than that of the third magnetic steel 41 .

[0067] Further, the magnetic fastener unit 50 also includes a second magnetic steel (not shown), which is arranged at the end of the fastener 51 away from the first magnetic steel 52, that is, the first magnetic steel 52 and the second magnetic steel are respectively located at the two ends of the fastener 51. The magnetic pole of the second magnetic steel at the end away from the fastener 51 is opposite to the magnetic pole of the first magnetic steel 52 at the end away from the fastener 51, that is, the magnetic poles at the two ends of the fastener 51 are opposite. It can be understood that the magnetic poles at the two ends of the fastener 51 are oppositely arranged, that is, the magnetic pole of the second magnetic steel at the end away from the fastener 51 is the S pole, then correspondingly, the magnetic pole of the first magnetic steel 52 at the end away from the fastener 51 is the N pole; or, the magnetic pole of the second magnetic steel at the end away from the fastener 51 is the N pole, then correspondingly, the magnetic pole of the first magnetic steel 52 at the end away from the fastener 51 is the S pole.

[0068] The valve is initially used as an ordinary valve, and it is assumed that the first magnet 52 and the third magnet 41 are in a repulsive state, that is, the handle is not locked and can be rotated; when the ordinary valve needs to be switched to a magnetically controlled valve, the user can unscrew the magnetic fastener unit 50, and then extend the other end of the magnetic fastener unit 50 into and install it in the connecting hole 31, so that the second magnet and the third magnet 41 attract each other, so that when the handle is rotated to a predetermined position, the third magnet 41 is stuck in the locking hole 32 under the suction action of the second magnet, that is, the handle is locked, so that the ordinary valve is converted into a magnetically controlled valve.

[0069] Specifically, a second fixing hole (not shown) is provided at one end of the fastener 51 away from the first fixing hole 511 , and the second magnetic steel is installed in the second fixing hole.

[0070] Preferably, the magnetic force of the second magnetic steel is equal to the magnetic force of the first magnetic steel 52 to ensure that the force between the two and the third magnetic steel 41 is consistent during use. Of course, in other embodiments, the magnetic force of the second magnetic steel may not be equal to the magnetic force of the first magnetic steel 52, which can be set according to actual conditions.

[0071] Furthermore, if Figure 2 As shown, the multifunctional valve 100 also includes an identification unit 70, which is arranged between the handle 30 and the magnetic fastening unit 50, and identifies the attraction or repulsion state between the magnetic fastener unit 50 and the magnetic unit 40, so that the user can intuitively obtain the state between the magnetic fastener unit 50 and the magnetic unit 40, thereby greatly facilitating the user's operation and switching.

[0072] In one embodiment, the identification unit 70 includes a first identification 71 and a second identification 72. The first identification 71 is arranged at one end of the magnetic fastening unit 50, and the second identification 72 is arranged at the connecting hole 31. When the first identification 71 and the second identification 72 cooperate, the first magnetic inductance 52 and the third magnetic steel 41 at the same position of the valve body 10 have the same magnetic pole, and the two repel each other. The multifunctional valve 100 can be used as an ordinary valve and can be opened and closed freely; when the first identification 71 and the second identification 72 are far away from each other, the first magnetic inductance 52 and the third magnetic steel 41 at the same position of the valve body 10 have opposite magnetic poles, and the two attract each other. The multifunctional valve 100 can be used as a magnetically controlled valve.

[0073] In another embodiment, as 2 and Figure 8 As shown, the identification unit 70 includes two first identifications 71 and two second identifications 72, the two first identifications 71 are respectively arranged on one of the magnetic fastening units 50 and at the connection hole 31 of the handle 30 corresponding to the magnetic fastening unit 50; the two second identifications 72 are respectively arranged on the other magnetic fastening unit 50 and at the locking hole 32 of the handle corresponding to the magnetic fastening unit 50;

[0074] The first mark 71 on the magnetic fastener unit 50 matches the first mark 71 at the locking hole 32 to indicate that the magnetic fastener unit 50 and the magnetic unit 40 repel each other; the first mark 71 on the magnetic fastener unit 50 matches the second mark 72 at the locking hole 32 to indicate that the magnetic fastener unit 50 and the magnetic unit 40 attract each other.

[0075] It can be understood that when the first mark 71 on the magnetic fastener unit 50 is close to the first mark 71 at the locking hole 32 on the handle 30 (i.e., matches the first mark 71 at the locking hole 32), the first magnetic induction 52 and the third magnet 41 at the same position of the valve body 10 have the same magnetic pole, and the two repel each other. The multifunctional valve 100 can be used as an ordinary valve and can be opened and closed freely; when the first mark 71 on the magnetic fastener unit 50 is close to the second mark 72 at the locking hole 32 on the handle 30 (i.e., matches the second mark 72 at the locking hole 32), the first magnetic induction 52 and the third magnet 41 at the same position of the valve body 10 have opposite magnetic poles, and the two attract each other. The multifunctional valve 100 can be used as a magnetically controlled valve and can only be closed.

[0076] Preferably, the first mark 71 is a red layer, and the second mark 72 is a blue layer; when the red layer matches the red layer, it indicates that the first magnetic induction 52 and the third magnetic steel 41 at the same position of the valve body 10 have the same magnetic pole, and when the red layer matches the blue layer, it indicates that the first magnetic induction 52 and the third magnetic steel 41 at the same position of the valve body 10 have opposite magnetic poles. Of course, in other embodiments, the first mark 71 and the second mark 72 can also be other structures, such as fonts, dots and other specific identification features.

[0077] like Figure 3 as well as Figure 7 As shown, the mechanical fastener 60 includes a main body 61 and a boss 62. The main body 61 can be threadedly connected to the connecting hole 31. The handle 30 is also provided with a through hole 35. The through hole 35 is located between the connecting hole 31 and the locking hole 32, and connects the connecting hole 31 and the locking hole 32. One end of the boss 62 can extend from the through hole 35 into the locking hole 32 to press the magnetic unit 40 into the mounting hole 11, or the boss 62 extends into the mounting hole 11. When the boss 62 presses the magnetic unit 40 into the mounting hole 11, it can contact the handle 30 to lock; when the boss 62 extends into the mounting hole 11, mechanical locking can be achieved. It can be understood that the free switching of the magnetic control valve and the mechanical locking valve can be achieved by controlling the mechanical fastener 60.

[0078] Preferably, the shape of the main body 61 matches the shape of the connecting hole 31, so that the main body 61 can be installed in the connecting hole 31. In this embodiment, the main body 61 is cylindrical.

[0079] The main body 61 and the boss 62 are configured as an integral unit to facilitate the overall processing of the mechanical fastener 60 .

[0080] Furthermore, if Figure 7 and Figure 8As shown, the aperture of the locking hole 32 is larger than the aperture of the through hole 35, and smaller than the aperture of the connecting hole 31. That is, the aperture of the connecting hole 31 is larger than the aperture of the locking hole 32, and the aperture of the locking hole 32 is larger than the aperture of the through hole 35; thus, steps are formed at the bottom of the connecting hole 31 and the locking hole 32, respectively, so that the magnetic fastening unit 50 and the third magnetic steel can respectively abut on the steps.

[0081] Preferably, the axis of the locking hole 32, the axis of the through hole 35 and the axis of the connecting hole 31 are arranged to coincide with each other. It is understandable that the coincidence of the axes of the three can make the magnetic fastener unit 50 and the magnetic unit 40, and the mechanical fastener 60 and the magnetic unit 40 cooperate with each other.

[0082] like Figure 1 and Figure 2 As shown, the present invention also provides a multifunctional valve assembly 200, which includes a multifunctional valve 100 and a special key 210. The multifunctional valve 100 adopts the above-mentioned multifunctional valve 100, and the special key 210 is used to screw the magnetic fastener unit 50 or the mechanical fastener 60 into / out of the connecting hole 31.

[0083] Preferably, a connecting portion 512 is provided on the magnetic fastener unit 50 and / or the mechanical fastener 60 , and the connecting portion 512 is arranged away from the valve body 10 .

[0084] Specifically, the connecting portion 512 is arranged at an end of the fastener 51 away from the first magnet 52 or an end of the main body 61 away from the protruding column 62, and one end of the special key 210 has an adapter portion 211, which is sleeved on the matching portion 512 so that the special key 210 can screw the fastener 51 or the main body 61 into / out of the connecting hole 31.

[0085] The switching process of the multifunctional valve 100 is described below:

[0086] (1) Switching between ordinary valves and magnetic control valves

[0087] The user unscrews the magnetic fastener unit 50 with the special key 210, swaps the two magnetic fastener units 50 or swaps the two ends of the magnetic fastener unit 50 to make the magnetic fastener unit 50 and the magnetic unit 40 attract or repel each other, thereby completing the switching of the functions of the two.

[0088] (2) Switching between magnetically controlled valves, mechanical locking valves and ordinary valves

[0089] The user unscrews the magnetic fastener unit 50 with the special key 210, and then screws the mechanical fastener 60 into the connecting hole 31. Under the action of the boss 62, the third magnetic steel 41 is pressed into the mounting hole 11, and the handle 30 is unlocked, thereby realizing the switching between the magnetic control valve and the ordinary valve.

[0090] The mechanical fastener 60 is continuously tightened to allow the boss 62 to extend into the mounting hole 11 to lock the handle 30 , thereby realizing the switching between the magnetically controlled valve and the mechanically locked valve.

[0091] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
