Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household pipeline valve body, in particular to a mechanical controllable valve. BACKGROUND

[0002] With the sustained and rapid development of China's economy and the acceleration of urbanization process, the booming development of commercial housing market. Under this background, part of the residents buy commercial housing and do not immediately move in, which puts forward new requirements for the valve on the household pipeline: the pipeline cannot be opened at will without opening, and the valve can be operated after formal account opening.

[0003] In the prior art, the commonly used valve on the household pipeline mainly includes a ball valve and a stop valve. Among them, the ball valve is widely used because of its simple structure and convenient operation (the handle is rotated by 90° to realize the switching of on-off). However, this convenient operation mode also has certain safety hazards: due to the lack of anti-misoperation mechanism, the ball valve is easily opened by mistake due to unconscious misoperation or children's play, thereby causing safety accidents.

[0004] At present, there are also some valve products with lock control function on the market, but mainly adopt magnetic control mode. This magnetic control type structure has obvious defects: it has high requirements for the use environment, and the magnet is easy to demagnetize, which causes the lock control function to fail and cannot persistently ensure the safety of the pipeline. At the same time, some products need to carry a special opening tool, which is not convenient to use.

[0005] Therefore, it is urgent to develop a mechanical controllable valve which can effectively prevent misoperation, has stable and reliable lock control function, and is convenient to operate, so as to meet the actual needs of users. CONTENT OF THE INVENTION

[0006] The technical problem to be solved by the present application is to provide a mechanical controllable valve which adopts a mechanical structure design and can effectively prevent safety hazards caused by misoperation and facilitate normal operation of users after account opening.

[0007] The technical scheme adopted by the present application is: a mechanical controllable valve, comprising a valve body, a valve ball and a handle, the valve body is provided with a mounting seat, the surface of the mounting seat is provided with a limiting piece, the handle is arranged at the mounting seat and connected with the valve ball, the handle is rotated to drive the valve ball to rotate in the valve body to switch the conduction and interruption of the valve body, the end of the handle is sleeved with a lock stopper, the limiting piece acts on the lock stopper sleeved on the end of the handle and limits the rotation of the lock stopper; the lock stopper can be withdrawn from the end of the handle under external force, at this time the handle is freely rotated.

[0008] Compared with the prior art, the mechanical controllable valve has the advantages that: the mechanical lock control structure is adopted, the anti-misoperation function is realized through cooperation of the limiting piece and the lock stopper, the shortcomings of the existing magnetic control valve, such as easy demagnetization and poor stability, are overcome, and the lock control function is ensured to be effective for a long time. When the lock stopper is subjected to external force, the lock stopper can retreat from the handle end portion, without the need to carry a special opening tool, so that the user can conveniently perform daily operation after opening. Meanwhile, when no external force is applied, the limiting effect of the limiting piece on the lock stopper can effectively prevent misoperation caused by unintentional touching or children's playing. Compared with the shortcomings of the magnetic control valve that is easily affected by the environment, the mechanical lock control structure is not affected by the external environment, has a longer service life and more stable performance. The mechanical controllable valve is suitable for water, non-corrosive liquid, air, saturated steam and various media, and can meet the use requirements of various indoor pipelines in buildings.

[0009] In conclusion, the mechanical controllable valve can effectively solve the problem that the existing indoor pipeline valve is easily misoperated, has the advantages of reliable structure, convenient operation and wide applicability, and can be widely applied to indoor pipeline systems of commodity houses.

[0010] In some embodiments of the present application, the mounting seat is a circular tubular structure, and the limiting piece includes a first limiting protrusion and a second limiting protrusion arranged on the surface of the mounting seat, and the first limiting protrusion and the second limiting protrusion are symmetrically arranged on both sides of the mounting seat.

[0011] The first limiting protrusion and the second limiting protrusion are symmetrically arranged, so as to accurately control the rotation range of the handle. The double-side limiting structure provides more stable limiting effect, and prevents the handle from being excessively rotated to damage the internal structure of the valve.

[0012] In some embodiments of the present application, the lock stopper is provided with a supporting leg, and the supporting leg is located at the outer periphery of the mounting seat. When the handle is located at the fully closed or fully opened valve body, one side surface of the supporting leg is in contact with the second limiting protrusion and limits the rotation of the lock stopper and the handle to the direction of the second limiting protrusion. The supporting leg is located at the outer periphery of the mounting seat, and does not affect the main structure of the valve.

[0013] The present application has good anti-misoperation effect. In the fully opened or closed state of the valve, the supporting leg is in automatic contact with the limiting protrusion, and a reliable mechanical lock mechanism is formed. The mechanical lock structure will not fail due to environmental factors (such as temperature, magnetic field, etc.).

[0014] In some embodiments of the present application, the force on the locking device moves along the length of the handle; moving the locking device away from the mounting base causes the support leg to move away from the mounting base, at which point the locking device rotates with the handle and does not contact the second limiting protrusion; moving the locking device towards the mounting base causes the support leg to move towards the mounting base, at which point the locking device contacts the second limiting protrusion and rotation of the locking device and handle towards the second limiting protrusion is blocked.

[0015] The operation is simple and intuitive, and users can easily understand and master it. No special tools are required, and the function can be switched by applying an axial force. The locking and unlocking states can be switched by simple axial movement; when moving away from the mounting base, the support leg is disengaged from the limit, allowing free operation; when moving towards the mounting base, it automatically enters the locked state to prevent accidental operation. The locking can only be released by actively applying an axial force, reducing the likelihood of accidental operation.

[0016] In some embodiments of the present application, the handle is provided with a mounting hole, and a fixed plug is detachably arranged at the mounting hole. The fixed plug at the mounting hole limits the locking device from moving away from the end of the handle.

[0017] The fixed plug serves as a mechanical stop to reliably limit the movement of the locking device. It prevents the locking device from accidentally disengaging from the end of the handle, ensuring that the locking function remains effective. It provides an additional level of safety protection, further reducing the risk of accidental operation.

[0018] In some embodiments of the present application, the valve ball surface is provided with a channel for the medium to pass through, and the valve ball is connected with a valve stem. The valve stem passes through the mounting base and is connected with the handle, and rotation of the handle drives the valve ball to rotate through the valve stem. The valve stem, handle, and valve ball form a direct mechanical transmission chain. The rotation angle of the handle is consistent with the rotation angle of the valve ball, which can be accurately controlled by the user.

[0019] In some embodiments of the present application, the locking device surface is provided with a U-shaped notch, and the valve stem is embedded in the U-shaped notch to limit the travel limit of the locking device; when the locking device moves to disengage the U-shaped notch from the valve stem, the locking device moves away from the end of the handle.

[0020] The U-shaped notch and the valve stem are embedded and matched to form a simple and effective positioning mechanism. No additional positioning parts are required, reducing the number of parts and making the structure compact without increasing the overall size. The surrounding structure of the U-shaped notch on the valve stem provides good self-locking effect, preventing it from disengaging on its own in normal use, enhancing the stability of the overall structure.

[0021] In some embodiments of the present application, the end of the handle is provided with two downwardly bent bars, and the included angle between the two bars is 90 degrees. The bars are located on the outer periphery of the mounting base, and the first limiting protrusion is located between the two bars.

[0022] The 90-degree angle between the two stop bars corresponds to the standard rotation angle of the valve switch, ensuring accurate positioning of the valve during switching and preventing internal damage caused by excessive rotation. The first limiting protrusion is located between the two stop bars, providing reliable mechanical limiting.

[0023] In some embodiments of the application, contact between the first limiting protrusion and either stop bar indicates that the handle has reached the limit of its travel, and contact between both stop bars and the first limiting protrusion indicates that the valve body is fully open or fully closed. The cooperation between the limiting protrusion and the stop bars precisely controls the rotation angle of the handle, allowing the operator to clearly perceive when the valve has reached the limit position.

[0024] In some embodiments of the application, when the handle is in the fully closed or fully open state of the valve body, one side of the foot contacts the second limiting protrusion, one of the stop bars contacts the first limiting protrusion, and the first and second protrusions limit the rotation of the handle. The contact between one side of the foot and the second limiting protrusion provides a limit to the rotation of the handle to one side, and the contact between the stop bar and the first limiting protrusion provides a limit to the rotation of the handle to the other side. The cooperation of the two protrusions limits the movement of the handle in any direction. The two limiting points share the stress, reducing the stress concentration at a single point.

[0025] On the basis of common general knowledge in the art, the various embodiments described above can be combined arbitrarily. BRIEF DESCRIPTION OF DRAWINGS

[0032] The present application will now be described in detail with reference to the accompanying drawings.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] A mechanically controllable valve, Example 1, as follows: Figures 1 to 2 As shown, the device includes a valve body 1, a valve ball 2, and a handle 3. A mounting base 4 is provided on the valve body 1, and a limiting element is provided on the surface of the mounting base 4. The handle 3 is located at the mounting base 4 and connected to the valve ball 2. Rotation of the handle 3 causes the valve ball 2 to rotate within the valve body 1, switching the valve body 1 between conduction and cutoff. A locking device 6 is fitted onto the end of the handle 3. The limiting element acts on the locking device 6 fitted onto the end of the handle 3 and restricts the rotation of the locking device 6. The locking device 6 can be retracted from the end of the handle 3 under external force, at which point the handle 3 can rotate freely. The locking device 6 of this application can be retracted from the end of the handle 3 under external force, eliminating the need for a special opening tool and facilitating daily operation after opening the valve. Simultaneously, when no external force is applied, the limiting element's restriction on the locking device 6 effectively prevents accidental operation due to unintentional contact or children playing.

[0035] This application adopts a purely mechanical locking structure, which achieves the function of preventing misoperation through the cooperation of the limit component and the locking device 6. It overcomes the shortcomings of existing magnetic control valves, such as easy demagnetization and poor stability, and ensures that the locking function is effective for a long time.

[0036] Example 2, as Figures 1 to 4 As shown, the mounting base 4 is a cylindrical tubular structure. The limiting component includes a first limiting protrusion 7 and a second limiting protrusion 8 disposed on the surface of the mounting base 4. The first limiting protrusion 7 and the second limiting protrusion 8 are symmetrically arranged on both sides of the mounting base 4. The symmetrical arrangement of the first limiting protrusion 7 and the second limiting protrusion 8 enables precise control of the rotation range of the handle 3. Furthermore, the double-sided limiting structure provides a more stable limiting effect, preventing excessive rotation of the handle 3 from damaging the internal structure of the valve.

[0037] The lock 6 is provided with a foot 9 located at the outer periphery of the mounting base 4. When the handle 3 is in the fully closed or fully open state of the valve body 1, one side of the foot 9 is in contact with the second limiting protrusion 8 and limits the rotation of the lock 6 and the handle 3 to the second limiting protrusion 8. The foot 9 is located at the outer periphery of the mounting base 4 and does not affect the main structure of the valve. The application has good anti-misoperation effect. In the fully open or closed state of the valve, the foot 9 will automatically contact the limiting protrusion to form a reliable mechanical locking mechanism. This mechanical locking structure will not fail due to environmental factors (such as temperature, magnetic field, etc.).

[0038] The force on the lock 6 moves along the length direction of the handle 3. When the lock 6 moves away from the mounting base 4, the foot 9 is also moved away from the mounting base 4. At this time, the lock 6 rotates with the handle 3 and does not contact the second limiting protrusion 8. When the lock 6 moves towards the mounting base 4, the foot 9 is also moved towards the mounting base 4. At this time, the lock 6 is in contact with the second limiting protrusion 8, and the rotation of the lock 6 and the handle 3 to the second limiting protrusion 8 is blocked. The operation action is simple and intuitive, and users can easily understand and master it. Without special tools, the function switching can be realized by applying axial force. The switching between the locking and unlocking states is realized by simple axial movement. When moving away from the mounting base 4, the foot 9 is disengaged from the limiting and allows free operation. When moving towards the mounting base 4, it automatically enters the locking state to prevent misoperation. The axial force needs to be actively applied to release the lock, which reduces the possibility of accidental operation.

[0039] The handle 3 is provided with a mounting hole 10, and a fixed plug 11 is detachably arranged at the mounting hole 10. The fixed plug 11 located at the mounting hole 10 limits the lock 6 from moving away from the end of the handle 3. The fixed plug 11 serves as a mechanical stopper to reliably limit the movement of the lock 6. It prevents the lock 6 from accidentally disengaging from the end of the handle 3 and ensures that the locking function is continuously effective. It provides an additional safety protection level and further reduces the risk of misoperation.

[0040] The valve ball 2 is provided with a channel 12 for medium passing through, and the valve ball 2 is connected with a valve rod 13. The valve rod 13 passes through the mounting base 4 and is connected with the handle 3. The rotation of the handle 3 drives the valve ball 2 to rotate through the valve rod 13. The valve rod 13, the handle 3 and the valve ball 2 form a direct mechanical transmission chain. The rotation angle of the handle 3 is consistent with the rotation angle of the valve ball 2, which can be accurately controlled by the user.

[0041] The lock 6 is provided with a U-shaped notch 14 on the surface, the valve stem 13 is embedded in the U-shaped notch 14 to limit the stroke limit of the lock 6; when the lock 6 moves to make the U-shaped notch 14 disengage from the valve stem 13, the lock 6 retreats from the end of the handle 3. The embedded cooperation of the U-shaped notch 14 and the valve stem 13 forms a simple and effective positioning mechanism. Without additional positioning parts, the number of parts is reduced, the structure is compact, and the overall size is not increased. The surrounding structure of the U-shaped notch 14 to the valve stem 13 provides good self-locking effect, which will not disengage automatically in the normal use state, and enhances the stability of the overall structure.

[0042] The other contents of Example Two are the same as those of Example One.

[0043] Example Three, as shown in Figures 1 to 4 The handle 3 is provided with two downwardly bent blocking strips 15 at the end, the included angle between the two blocking strips 15 is 90 degrees, and the blocking strip 15 is located on the outer periphery of the mounting seat 4, and the first limiting protrusion 7 is located between the two blocking strips 15. The 90-degree included angle design between the two blocking strips 15 completely corresponds to the standard rotation angle of the valve switch, ensuring accurate positioning of the valve during switching and preventing internal damage caused by excessive rotation. The first limiting protrusion 7 is located between the two blocking strips 15 to form reliable mechanical limiting.

[0044] When the first limiting protrusion 7 contacts any blocking strip 15, the handle 3 rotates to the limit stroke, and when the two blocking strips 15 contact the first limiting protrusion 7, the valve body 1 is fully opened or fully closed. The cooperation of the limiting protrusion and the blocking strip 15 accurately controls the rotation angle of the handle 3, and the operator can clearly perceive that the valve reaches the limit position.

[0045] When the handle 3 is in the fully closed or fully open valve body 1 state, one side of the supporting leg 9 contacts the second limiting protrusion 8, one of the blocking strips 15 contacts the first limiting protrusion 7, and the first protrusion and the second protrusion limit the rotation of the handle 3. The side of the supporting leg 9 in contact with the second limiting protrusion 8 provides a limit to the rotation of the handle 3 to one side, and the blocking strip 15 in contact with the first limiting protrusion 7 provides a limit to the rotation of the handle 3 to the other side. The two protrusions cooperate to lock the movement of the handle 3. Double-protrusion cooperation prevents accidental rotation in any direction. Two limiting points share the stress, reducing the stress concentration of a single point.

[0046] The other contents of Example Three are the same as those of Example One or Example Two.

The above description of the examples is only used to help understand the application and the core idea. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the application without departing from the principles of the application, and these improvements and modifications also fall within the protection scope of the claims of the application.
