DETAILED DESCRIPTION

[0041] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0042] Embodiment 1: This embodiment is a fast switching independent valve, such as Figure 1 and Figure 2As shown, it includes a valve body 1 and a valve module which are separately arranged. The valve module includes a mechanical module and an intelligent module 6 which are installed in a switchable manner. The valve module is clamped on the valve body to form an independent valve as a whole. The valve module selects a mechanical module or an intelligent module 6 to be combined with the valve body 1 according to the application scenario and functional requirements to form a mechanical valve or an intelligent valve.

[0043] like Figure 1 and Figure 3 As shown, a valve seat 11 is provided on the valve body 1. The valve seat is circular, a through hole is provided in the center of the valve seat, and a circle of positioning round platforms 111 is provided around the through hole. A plurality of valve seat screw holes 112 are provided on the surface of the valve seat. Generally, four valve seat screw holes are provided and distributed in a cross direction. The valve seat 11 is integrally formed with the valve body 1. The valve body can be various types such as ball valve, butterfly valve, stop valve, etc. According to different construction requirements, the valve body can be fixed or telescopic.

[0044] The valve body 1 includes a valve stem 12 for controlling opening and closing, and the valve stem 12 passes through the central hole of the valve seat 11. Figure 3 As shown, the valve stem includes a valve stem key 122 located at the end, a circle of valve stem groove 121 is provided on the side wall of the valve stem, and a valve stem O-ring 13 is inserted into the valve stem groove.

[0045] A fixed seat 2 is sleeved on the valve stem, and the fixed seat 2 is fixedly connected to the valve seat 11. Figure 4As shown, the fixed seat 2 is circular, with a center hole 21 opened in the center of the fixed seat, a positioning step hole 22 is arranged on the bottom surface of the fixed seat 2 around the center hole 21, and four screw step holes 25 are arranged on the surface of the fixed seat around the center hole 21. The screw step holes are distributed in a cross direction, corresponding to the position of the valve seat screw hole 112 on the valve seat 11. In order to reduce the material of the fixed seat, a concave material reduction groove 26 is formed between the screw step holes. At least a pair of clamping platforms 23 are arranged at the lower part of the side of the fixed seat. In order to ensure a stable connection, four clamping platforms 23 are arranged in this embodiment. The clamping platforms are arranged in a cross direction. The clamping platforms protrude from the lower part of the side of the fixed seat. The size of the bottom of the fixed seat 2 surrounded by the clamping platforms is consistent with the size of the valve seat, so that the valve seat can be embedded in the bottom of the fixed seat surrounded by the clamping platforms. The surface of the clamping platform 23 is inclined outward to form a guide slope, so that the mechanical module or the intelligent module can be inserted into the corresponding snap structure. In order to facilitate the installation of mechanical modules or intelligent modules, a pair of bosses 24 are also provided on the side of the fixed seat 2. The two bosses are arranged relative to the center of the fixed seat. The bosses 24 and the clamping platforms 23 are staggered. The preferred boss is located between the two clamping platforms. A conformal reduction groove 26 is also provided on the bottom of the boss to reduce the manufacturing materials. The fixed seat 2 is inserted into the valve stem 12 through the center hole 21. The bottom surface of the fixed seat abuts against the valve seat. The positioning round table 111 is completely aligned with the positioning step hole 22. The screw step hole 25 is aligned with the valve seat screw hole 112. The fastening machine screw 5 passes through the screw step hole and is threadedly connected with the valve seat screw hole to fix the fixed seat 2 on the valve seat 11. Through the above structure, a platform connected with the valve module is formed on the valve body, and the valve module is quickly installed by clamping. The fixed seat is easy to install and also easy to replace.

[0046] As a preferred solution of this embodiment, the mechanical module includes a valve cover 3 and a valve handle 4. Figure 5 and Figure 6 As shown, the valve cover 3 includes a circle of outer skirt 32, and a circle of inner clamping ring 33 is arranged inside the valve cover on the inner side of the outer skirt 32. The inner clamping ring is flush with the outer skirt. The outer skirt 32 is arranged outside the inner clamping ring 33, which is not only decorative but also prevents the inner clamping ring from being easily pried from the outside to cause the valve cover to fall off, thereby playing an anti-theft protection role. A central limiting hole 35 is arranged on the inner top of the valve cover 3. Notches 36 are evenly spaced on the edge of the inner clamping ring 33, preferably with 4 notches, and the notches divide the inner clamping ring into a plurality of inner cards 38. The inner cards are provided with matching card slots 34 corresponding to the card platform 23. The notch 36 is used to cooperate with the boss 24. When installing, the boss is aligned with the notch and slides into the notch, which plays a guiding and limiting role in the installation, and is convenient for the closed-eye alignment installation of the mechanical module in a limited space. The notch is designed to be square, and the two sides of the notch are connected to the bottom edge by a small fillet transition. The small fillet design can avoid the injection stress concentration and the elastic failure of the inner card 38.

[0047] The valve handle 4 adopts a Z-shaped handle 41, with a rubber-plastic body 42 coated on the hand-held end, and a handle groove 43 is opened on the front end of the valve handle, and the shape of the handle groove matches the shape of the valve stem key 122. A handle groove 31 is horizontally opened at the upper position of the side wall of the valve cover, and the handle groove passes through the outer skirt and the inner clamp ring, and is connected to the inside of the valve cover. The front end of the valve handle 4 is inserted into the valve cover 3 through the handle groove. When the mechanical module and the valve body are installed, the top end of the valve stem 13 penetrates the handle groove 31 of the valve handle, and the valve stem key 122 is engaged with the handle groove. The valve stem key passes through the handle groove and its top end is inserted into the central limit hole 35 at the bottom of the valve cover. Under the restriction of the handle groove and the valve stem, the valve handle can only be rotated horizontally with the valve stem as the center, and the handle groove is opened at 90° with the center of the valve cover 3. Under the restriction of the handle groove opening, the valve handle can only be rotated within a range of 90°, that is, the valve is from fully open to fully closed.

[0048] As a preferred solution of this embodiment, Figure 2 and Figure 7 As shown, the smart module includes a module seat 61 and a module cover 63 that are arranged to be interlocked, and the module seat and the module cover cooperate to form a housing for accommodating the hardware device. Fig. 9 As shown, an inner retaining wall 611 is arranged on the edge of the upper edge of the module seat, and a sealing groove 612 is arranged on the upper edge of the module seat close to the inner retaining wall, a module sealing ring 67 is arranged in the sealing ring, and self-tapping screw step holes 616 are arranged at the four corners of the upper edge of the module seat, and a material reduction and anti-shrinkage hole 618 is arranged in the concave side of the self-tapping screw step, which reduces material loss and reduces the problem of shrinkage marks in injection molding production. Fig.11 As shown, a sealing rib 634 is provided on the cover edge of the module cover 63 corresponding to the sealing groove 612, and screw holes 635 are provided at the four corners of the cover edge of the module cover. During installation, the sealing rib 634 of the module cover 63 is aligned with the sealing groove 612, and the module cover 63 is installed into the inner retaining wall 611 of the module seat 61, so that the screw hole 635 is aligned with the self-tapping screw step 616, and the self-tapping screw 6012 is tightened through the self-tapping screw step 616 and then screwed into the screw hole 635 until the sealing rib 634 presses the module sealing ring 67 so that only a decorative seam is left between the module cover 63 and the module seat 61, and the installation of the module cover and the module seat is completed.

[0049] The module seat 61 is divided into a hardware compartment and a battery compartment 617. The battery compartment is provided with a battery 68. A circuit board 62 and a reducer assembly 69 are provided in the hardware compartment. The hardware compartment includes a first slot body located in the inner circle and a second slot body located outside the upper part of the first slot body. The reducer assembly is installed in the first slot body. A valve stem hole column 6111 is provided at the bottom of the first slot body, i.e., the bottom of the module seat 61. An inner hole 6113 for inserting the valve stem 11 is provided in the valve stem hole column. When the valve stem is inserted into the inner hole, the valve stem O-ring 13 on the valve stem is squeezed by the inner hole of the valve stem hole column to form a seal, which plays a sealing role for the hardware compartment. A plurality of reducer gear shaft holes 613 are also provided at the bottom of the first slot body. The reduction gear of the reducer assembly is installed on the reducer gear shaft hole, and a motor is installed. The motor is connected to the reduction gear in transmission. At the same time, the valve stem penetrates the first slot body through the inner hole and is connected to the reduction gear in transmission. This makes the motor rotate to drive the valve stem to rotate, thereby realizing the opening and closing of the valve. After the reducer gear and motor are installed, they are covered with a plastic shell for protection, and then sealed with sealant to seal and isolate the first trough body from the second trough body. A circuit board is installed in the second trough body, and the wiring of the motor and the battery is connected to the circuit board 62. The installation of the circuit board is specifically that a plurality of circuit board lower blocks 614 are arranged between the bottom and the side wall of the first trough body. The circuit board lower block is L-shaped, including a transverse pad and a side support portion. The circuit board 62 is placed on the circuit board lower block, the bottom of the circuit board 62 is in contact with the pad, and the side of the circuit board is against the support portion. The circuit board lower block firmly restricts and fixes the circuit board. A plurality of circuit board upper clamps 615 are also arranged on the side wall of the second trough body. The position of the circuit board upper clamp is higher than the pad of the circuit board lower block, and the distance between the circuit board upper clamp and the pad is equal to the thickness of the circuit board. After the circuit board is placed on the circuit board lower block, the circuit board 62 is pressed against the circuit board lower block by the circuit board upper clamp. The structure of the circuit board lower stop and the circuit board upper clamp can fix the circuit board without screws, reduce parts, improve production efficiency, and avoid the module seat from contacting components on the circuit board as much as possible, ensuring effective use of the circuit board plane.

[0050] like Fig. 9 As shown, the battery compartment 617 includes a compartment bottom groove protruding from the bottom of the module seat 61, and a battery support edge arranged on the edge of the compartment bottom groove. The compartment bottom groove increases the height space for placing the battery so that the module seat can accommodate the battery. The battery support edge limits the battery, making the battery more stable in the battery compartment. Figure 7 As shown, a cover hole is provided on the module cover 63 corresponding to the battery compartment 617, and a battery end cover 66 and a battery threaded cover 64 are sequentially arranged in the cover hole to seal the battery. Fig.11As shown, the cover hole is a column hole structure, and a connecting internal thread 631 is provided on the inner side wall of the cover hole, and a clamping edge folded inward is provided on the lower edge of the cover hole, and an O-ring groove 632 is provided on the clamping edge, and a battery O-ring 65 is provided in the O-ring groove. The battery end cover 66 is provided with an outward folding pressing edge on the cover edge, and the battery end cover is covered on the cover hole and placed on the clamping edge, and the pressing edge of the battery end cover 66 presses on the battery O-ring 65. Fig.12 As shown, the battery threaded cover 64 is provided with a connecting external thread 641 on the outer side of the cover edge, and a threaded pressing ring 642 is provided on the top of the cover edge. The battery threaded cover 64 is screwed into the cover hole through a threaded connection, and the threaded pressing ring 642 presses on the outer side of the pressing edge of the battery end cover 66, pushing the battery end cover to press on the battery O-ring 65 until the pressed battery O-ring 65 is deformed and bottomed out, completing the sealing of the battery compartment and achieving a waterproof effect on the battery compartment. The battery threaded cover presses the battery O-ring through the battery end cover to avoid the battery O-ring from wrinkling when the battery threaded cover is rotated, which causes the seal to fail. In order to prevent the battery threaded cover from being turned or pried open by others, three assembly holes 643 are provided on the surface of the battery threaded cover 64. The three assembly holes are distributed in a triangular shape, and specific tools are required to match the assembly holes to screw the battery threaded cover into the cover hole. The irregular triangular distribution greatly reduces the possibility of arbitrary damage and disassembly of the battery threaded cover. After the battery threaded cover is tightened, the lead seal bean 6011 is installed in the assembly hole 643, and the lead seal bean and the assembly hole have an interference fit. Figure 8 As shown, it is ensured that the lead seal bean 6011 does not exceed the cover plane 637 of the module cover 63 to achieve the purpose of anti-disassembly, and the assembly of the smart module is completed. Figure 8 and Fig.11 As shown, a setting window hole 633 and a power button are provided on the cover surface 637 of the module cover 63, a transparent window 610 is installed on the setting window hole 633, and the transparent window is arranged in the window hole by ultrasonic welding or secondary injection molding. The power button is connected to the circuit board through a line.

[0051] like Fig.10 As shown, a circle of support ribs 6110 matching the shape of the fixed seat 2 is arranged at the bottom of the module seat 61, and the support ribs surround the valve stem hole column 6111. A plurality of buckles 619 cooperating with the clamping platform 23 are evenly spaced on the inner wall of the support ribs. Generally, four buckles are preferably arranged and distributed in a cross direction. Two positioning grooves 6112 are provided on the support ribs. The two positioning grooves are symmetrically arranged with the valve stem hole column as the center. The positioning grooves and the buckles are staggered and are preferably arranged between the two buckles. The width of the positioning groove is consistent with the width of the boss.

[0052] like Figure 1 and Figure 3As shown, when it is necessary to assemble into a smart valve, align the valve stem with the valve stem hole column of the smart module and slowly install it, align the support rib with the fixing seat 2 and align the boss with the positioning groove and insert it, snap the card into the buckle to complete the assembly. When it is necessary to assemble into a mechanical valve, align the valve stem with the center of the mechanical module, align the notch with the boss of the fixing seat, push the fixing seat into the inner clamp ring, snap the card into the card slot to complete the assembly. When it is necessary to replace the valve type on site, such as the intelligent transformation of a mechanical valve, first forcefully destroy the inner card and the card slot to make the buckle invalid, then remove the valve cover and valve handle as a whole, and install the smart module according to the steps of assembling the smart valve.

The valve seat 11 is integrally formed with the valve body 1. The valve body can be various types such as ball valve, butterfly valve, stop valve, etc. According to different construction requirements, the valve body can be fixed or telescopic.

[0055] The valve body 1 includes a valve stem 12 for controlling opening and closing, and the valve stem 12 passes through the central hole of the valve seat 11.

The screw step holes are distributed in a cross direction, corresponding to the position of the valve seat screw hole 112 on the valve seat 11. In order to reduce the material of the fixed seat, a concave material reduction groove 26 is formed between the screw step holes. At least a pair of clamping platforms 23 are arranged at the lower part of the side of the fixed seat. In order to ensure a stable connection, four clamping platforms 23 are arranged in this embodiment. The clamping platforms are arranged in a cross direction. The clamping platforms protrude from the lower part of the side of the fixed seat. The size of the bottom of the fixed seat 2 surrounded by the clamping platforms is consistent with the size of the valve seat, so that the valve seat can be embedded in the bottom of the fixed seat surrounded by the clamping platforms. The surface of the clamping platform 23 is inclined outward to form a guide slope, so that the mechanical module or the intelligent module can be inserted into the corresponding snap structure. In order to facilitate the installation of mechanical modules or intelligent modules, a pair of bosses 24 are also provided on the side of the fixed seat 2. The two bosses are arranged opposite to each other at the center of the fixed seat. The bosses 24 and the clamping platforms 23 are staggered. The preferred boss is located between the two clamping platforms. A conformal reduction groove 26 is also provided on the bottom of the boss to reduce the manufacturing materials. The fixed seat 2 is inserted into the valve stem 12 through the center hole 21. The bottom surface of the fixed seat abuts against the valve seat. The positioning round table 111 is completely aligned with the positioning step hole 22. The screw step hole 25 is aligned with the valve seat screw hole 112. The fastening machine screw 5 passes through the screw step hole and is threadedly connected with the valve seat screw hole to fix the fixed seat 2 on the valve seat 11.

[0056] The mechanical module includes a valve cover 3 and a valve handle 4. Figure 5 and Figure 6As shown, the valve cover 3 includes a circle of outer skirt 32, and a circle of inner clamping ring 33 is arranged inside the valve cover on the inner side of the outer skirt 32. The inner clamping ring is flush with the outer skirt. The outer skirt 32 is arranged outside the inner clamping ring 33, which is not only decorative but also prevents the inner clamping ring from being easily pried from the outside to cause the valve cover to fall off, thereby playing an anti-theft protection role. A central limiting hole 35 is arranged on the inner top of the valve cover 3. Notches 36 are evenly spaced on the edge of the inner clamping ring 33, preferably with 4 notches, and the notches divide the inner clamping ring into a plurality of inner cards 38. The inner cards are provided with matching card slots 34 corresponding to the card platform 23. The notch 36 is used to cooperate with the boss 24. When installing, the boss is aligned with the notch and slides into the notch, which plays a guiding and limiting role in the installation, and is convenient for the closed-eye alignment installation of the mechanical module in a limited space. The notch is designed to be square, and the two sides of the notch are connected to the bottom edge by a small fillet transition. The small fillet design can avoid the injection stress concentration and the elastic failure of the inner card 38. The valve handle 4 adopts a Z-shaped handle 41, with a rubber-plastic body 42 coated on the hand-held end, and a handle groove 43 is opened on the front end of the valve handle, and the shape of the handle groove matches the shape of the valve stem key 122. A handle groove 31 is horizontally opened at the upper position of the side wall of the valve cover, and the handle groove passes through the outer skirt and the inner clamp ring, and is connected to the inside of the valve cover. The front end of the valve handle 4 is inserted into the valve cover 3 through the handle groove. When the mechanical module and the valve body are installed, the top end of the valve stem 13 penetrates the handle groove 31 of the valve handle, and the valve stem key 122 is engaged with the handle groove. The valve stem key passes through the handle groove and its top end is inserted into the central limit hole 35 at the bottom of the valve cover. Under the restriction of the handle groove and the valve stem, the valve handle can only be rotated horizontally with the valve stem as the center, and the handle groove is opened at 90° with the center of the valve cover 3. Under the restriction of the handle groove opening, the valve handle can only be rotated within a range of 90°, that is, the valve is from fully open to fully closed.
