Meanwhile, integrated temperature-adjustable valves have a complex structure, are made entirely of plastic, and are essentially disposable, making them difficult to repair, operate, and install. Furthermore, these products exhibit unstable temperature regulation and significant differences in high and low pressure during water flow; their processing, assembly, and maintenance are also inconvenient.

The component is installed in the third chamber, and its outlet is connected to the mixed water outlet; the temperature regulating structure is installed in the main chamber, and its front end is connected to the first chamber and the second chamber respectively; the front end of the delay valve core component is connected to the temperature regulating structure, and its rear end is connected to the control component; the positioning sleeve is fastened to the inner wall of the main chamber, and the front end of the delay valve core component and the control component are located in the space inside the positioning sleeve; the delay valve core component is connected to the inlet of the flow limiting component through the main chamber; the main body component is installed in the lower shell of the protective sleeve; during construction, the upper shell of the protective sleeve is installed on the lower shell of the protective sleeve; after construction, the panel is sleeved on the rear end of the control component and connected to the main body component with screws, and the control wheel is sleeved on the rear end of the control component.
[0005] The one-way valve component allows for unidirectional water flow, preventing backflow. The control wheel triggers the delay valve core component, which can adjust the water output at high or low pressure to balance the water flow at other pressures, achieving a delay and constant flow effect. The flow limiting component ensures stable water pressure. The fit between the upper and lower protective shells prevents dirt from entering during construction.
[0006] The time-delay valve core component includes a float sleeve, a float component, a conical spring, a push rod, a first gasket, a first sealing ring, and a float cap. The float sleeve is a stepped cylindrical structure with an inner cavity. A partition separating the front and rear sides of the inner cavity is provided at the front end. A first mounting hole is provided on the front side of the partition, and a second mounting hole is provided on its rear side. A first drain hole penetrating the front and rear sides of the partition is provided. A threaded hole is provided in the first mounting hole, and the rear end of the temperature-regulating structure is installed in the first mounting hole and rotated by it. The front end of the float component... The float cover is movably inserted into the second mounting hole. It is fitted inside the rear end of the inner cavity of the float cover. The first sealing ring is fitted around the outer periphery of the float cover, with its outer periphery abutting against the wall of the inner cavity of the float cover. A third mounting hole is provided on the front side of the float cover, and a fourth mounting hole communicating with it is provided in the center of the third mounting hole. The fourth mounting hole penetrates the front and rear sides of the float cover. The first gasket is fitted inside the third mounting hole. The push rod includes an annular top plate, with a first guide post on one side and a... A second guide post is provided on the side. The first guide post passes through the first sealing ring and the fourth mounting hole and can slide along them. The annular top plate slides with the top rod, pressing against or moving away from the first gasket. There is a gap between the first guide post and the fourth mounting hole. The small-diameter end of the conical spring is sleeved on the outer circumference of the second guide post and abuts against the annular top plate. The large-diameter end of the conical spring is sleeved in the cavity at the rear end of the float component and abuts against the wall of the cavity. The inner cavity between the partition and the front end of the float component forms a first inner cavity. The inner cavity between the float and the float cover forms a second inner cavity; the second mounting hole has a second drainage hole leading to the outside of the float sleeve; the float has a third drainage hole penetrating its front and rear sides; the float sleeve is connected to the control component, and a drainage groove is provided at the connection point, the drainage groove connecting the inner cavity of the positioning sleeve and the inner cavity between the float cover and the control component; the inner cavity of the positioning sleeve is connected to the main chamber; the control component has a push rod for pushing the first guide post forward or releasing the first guide post. Water flowing out from the temperature regulating structure enters the first drainage hole and then enters the first inner cavity. A conical spring provides support for the push rod and the float component. When the control component is operated, it pushes the push rod forward, reducing the space of the first inner cavity, thereby draining the first cavity water from the second mounting hole and the second drainage hole into the main chamber; the third drainage hole essentially acts as a delay channel, while the first cavity water drains into the main chamber, the first cavity water also simultaneously enters the second inner cavity from the third drainage hole to form the second cavity water. When the push rod is pushed forward, the annular top plate of the push rod disengages from the first gasket, and the water in the second chamber flows out of the space behind the attachment sleeve from the gap between the first guide post and the fourth mounting hole of the push rod, and flows out from the drainage groove into the main chamber.
[0007] The diameter of the front end of the float sleeve is smaller than the diameter of the rear end of the float sleeve; the annular top plate of the top rod has a delay hole that extends through its front and rear sides. The delay hole is designed to control the delay time and water volume.
[0008] The control components include a rotary guide sleeve, a push rod positioning sleeve, a second sealing ring, a third sealing ring, a return spring, a second gasket, a fixing rubber sleeve, and a third gasket. The push rod is a rotary shaft push rod. The front end of the rotary guide sleeve is connected to the rear end of the float sleeve via a snap-fit fitting. The rear section of the rotary shaft push rod has a square post, and the rear end of the rotary guide sleeve has a square hole. The square post is fitted into the square hole and can slide along it. The fixing rubber sleeve is fitted onto the rear end of the rotary shaft push rod and abuts against the square post. The outer side of the middle section of the rotary shaft push rod has two retaining rings, namely a first retaining ring and a second retaining ring, with a gap between the two retaining rings. The groove is formed, with the first retaining ring located on the front side; the third gasket is sleeved on the outer periphery of the rotating shaft push rod and clamped between the second retaining ring and the rear side wall of the inner cavity of the rotating guide sleeve; the push rod positioning sleeve is sleeved on the front section of the inner cavity of the rotating guide sleeve, and the third sealing ring is sleeved on the outer periphery of the push rod positioning sleeve, with its outer surface abutting against the inner wall of the rotating guide sleeve; the second gasket is sleeved on the outer periphery of the rotating shaft push rod and close to the rear side wall of the push rod positioning sleeve; the return spring is sleeved on the outer periphery of the rotating shaft push rod, with one end abutting against the push rod positioning sleeve and the other end abutting against the second retaining ring; the middle section of the rotating guide sleeve is sleeved with... The second sealing ring is fitted around the positioning sleeve and is located within it. The outer side of the second sealing ring abuts against the inner wall of the positioning sleeve. The control wheel is fitted around the rear end of the rotating shaft push rod. The control wheel pushes the rotating shaft push rod forward, and the front end of the rotating shaft push rod moves forward along the push rod positioning sleeve, pushing against the push rod. Rotating the control wheel causes the rotating shaft push rod to push the rotating guide sleeve, which in turn drives the float sleeve to rotate. The float sleeve then drives the temperature control structure to adjust the flow ratio of hot and cold water. An adjusting ring with a limit rod is fitted around the rear end of the rotating guide sleeve. When the adjusting ring... When the ring is located outside the positioning sleeve, a positioning stud is provided inside the control wheel. When the control wheel is turned to the left to the maximum opening angle of the temperature regulating structure (full heat) and to the right to the maximum opening angle of the temperature regulating structure (full cold), the positioning stud abuts against the limiting rod of the adjusting ring when the temperature is at the full heat limit. Alternatively, a limiting member is provided at the rear end of the positioning sleeve, and the adjusting ring is sleeved on the rear end of the positioning sleeve. The limiting rod of the adjusting ring moves within the constraint range of the limiting member. When the control wheel is turned to the left to the maximum opening angle of the temperature regulating structure (full heat) and to the right to the maximum opening angle of the temperature regulating structure (full cold), the limiting member abuts against the limiting rod of the adjusting ring when the temperature is at the full heat limit. The cooperation between the square post and the square hole allows the rotating shaft push rod to rotate together with the rotating guide sleeve when it rotates. The third gasket is used to buffer the impact between the second retaining ring and the rear side wall of the inner cavity of the rotating guide sleeve, preventing damage or vibration. The third sealing ring can seal the gap between the push rod positioning sleeve and the inner wall of the rotating guide sleeve, preventing water from entering the control component. The second shim is designed to prevent the first retaining ring from impacting the rear wall of the push rod positioning sleeve when it is pushed forward, thus providing a buffering effect.
[0009] The one-way valve assembly includes a one-way valve sleeve, a first washer, a check valve assembly, an inlet water level line, an inlet water adjusting screw, a fourth sealing ring, a fifth sealing ring, and a sealing nut. The one-way valve sleeve has a through-hole. The check valve assembly is installed in the inlet section of the valve hole. The first washer is fitted inside the valve hole outside the check valve. The inlet water level line is tightened with the inlet water adjusting screw, which passes through the sealing nut. The outlet section of the valve hole is fitted onto the inner end of the sealing nut, and the outer circumference of the inner end of the sealing nut is fitted with… The fourth sealing ring is provided, and the fifth sealing ring is fitted around the outer periphery of the middle section of the sealing nut. The outer periphery of the fourth sealing ring is tightly against the inner wall of the outlet section of the one-way valve sleeve, and the outer periphery of the fifth sealing ring is tightly against the wall of the valve body. The first gasket of the hot one-way valve is close to the connection between the hot water inlet and the first chamber, and the first gasket of the cold one-way valve is close to the connection between the cold water inlet and the second chamber. The outlet section of the one-way valve sleeve of the hot one-way valve has a hole connecting the valve hole to the first chamber, and the outlet section of the one-way valve sleeve of the cold one-way valve has a hole connecting the valve hole to the second chamber. The first gasket, the fourth sealing ring, and the fifth sealing ring are provided to increase the sealing performance and prevent water leakage. Hot water from the hot water inlet enters the valve hole through the check valve component from the inlet of the one-way valve sleeve, and then enters the first chamber from the hole in the outlet section of the one-way valve sleeve. The cold water from the cold inlet enters the valve hole through the check valve component from the inlet of the one-way valve sleeve, and then enters the second chamber from the hole at the outlet section of the one-way valve sleeve.
[0010] The flow-limiting component includes a second washer, a pressure-reducing core, a sixth sealing ring, and a water outlet sealing screw. The rear end of the water outlet sealing screw has a screw groove, and its front end has a forward-opening drainage channel. A fourth drainage hole is formed on its side wall, connecting the drainage channel to the main chamber and acting as the inlet of the drainage channel. The pressure-reducing core is installed at the outlet of the drainage channel. The second washer is positioned on the drainage channel outside the pressure-reducing core, with its outer side abutting against the periphery of the hole communicating with the mixed water outlet. The second washer and the sixth sealing ring are used to increase sealing and prevent water leakage. Mixed water enters the drainage channel of the water outlet sealing screw from the main chamber through the fourth drainage hole, and then flows out from the drainage channel outlet through the third chamber and the mixed water outlet to the equipment requiring hot water.
[0011] Both the one-way valve component and the flow-limiting component are installed facing the wall. This arrangement facilitates replacement, maintenance, and disassembly. During maintenance, the water supply can be turned off using the one-way valve component without needing to disconnect the main water pipe switch.
[0012] The lower protective sleeve has a prismatic cross-section, and the upper protective sleeve matches the shape of the lower protective sleeve. The hot and cold water inlets of the valve body are located on the left and right sides in a horizontally symmetrical position, and the mixed water outlet is located at the top of the valve body. The use of prismatic shapes for both the lower and upper protective sleeves reduces the overall dimensions and lowers the overall cost.
[0013] It also includes concave and convex baffles; the lower shell of the protective sleeve has installation openings on its upper, lower, left, and right sides, with a lower arc-shaped opening on the bottom side of each installation opening, and slots on both sides of the installation hole; the lower side of the concave baffle has an upper arc-shaped opening, and the lower side of the convex baffle has an upper arc-shaped protrusion that matches the lower arc-shaped opening; during construction, the hot water inlet, cold water inlet, and mixed water outlet of the water pipe are connected to the valve body using sealing gaskets, nuts, and unions, respectively. The union is located inside the installation opening. The concave baffle is inserted into the slot of the installation opening with the union, and the union is clamped in the space between the lower and upper arc-shaped openings. The convex baffle is inserted into the slot of the installation opening without the union, and the upper arc-shaped protrusion of the convex baffle is embedded in the lower arc-shaped opening of the installation opening. The cooperation of the concave and convex baffles with the slots can prevent debris such as cement from entering the protective sleeve shell during construction, and it is also easy to remove after construction.
[0014] The valve body is provided with a drain hole on the lower side, which is connected to the main chamber. A cover is installed in the drain hole to seal the drain hole. A seventh sealing ring is fitted around the upper outer periphery of the cover, and the outer periphery of the seventh sealing ring abuts against the wall of the main chamber.
[0015] Compared with existing technologies, the advantages of this utility model are as follows: This device can automatically extend the time, so that the water output at high or low pressure is balanced with the water output at other pressures, achieving a constant flow effect; the temperature adjustment structure can adjust the hot and cold water in a staggered manner, preventing sudden changes in temperature; both the one-way valve component and the flow limiting component are installed facing the wall, which facilitates replacement, maintenance, and disassembly; during maintenance, the water supply can be turned off using the one-way valve component without disconnecting the main water pipe switch; it can achieve simultaneous control of the time delay switch and hot and cold temperature adjustment using the same control wheel, and can also control both cold and hot water output.

The outer surface of the push rod positioning sleeve 46 abuts against the inner wall of the rotary guide sleeve 45; the second gasket 50 is fitted around the outer periphery of the rotary shaft push rod 53 and close to the rear side wall of the push rod positioning sleeve 46; the return spring 49 is fitted around the outer periphery of the rotary shaft push rod 53, with one end abutting against the push rod positioning sleeve 46 and the other end abutting against the second retaining ring 532; the middle section of the rotary guide sleeve 45 is fitted inside the positioning sleeve 20 and can rotate around it; the second sealing ring 47 is fitted around the outer periphery of the rotary guide sleeve 45, and the second sealing ring 47 is fitted around the outer periphery of the rotary guide sleeve 45. The control wheel 27 is fitted onto the inner wall of the positioning sleeve 20. The control wheel 27 pushes the rotating shaft push rod 53 forward, and the front end of the rotating shaft push rod 53 moves forward along the push rod positioning sleeve 46 and pushes the top rod 33 forward. Rotating the control wheel 27, the rotating shaft push rod 53 pushes the rotating guide sleeve 45 to drive the float sleeve 30 to rotate. The float sleeve 30 drives the temperature adjustment structure to adjust the flow ratio of hot water and cold water. The rear end of the rotating guide sleeve 45 is fitted with an adjustment ring 22 with a limit rod. In this embodiment, there are two ways to match the adjusting ring 22 with the positioning sleeve 20. One way is that when the adjusting ring 22 is outside the positioning sleeve 20, the control wheel 27 is provided with a positioning stud 21. When the control wheel 27 is turned to the left to the maximum opening angle of the temperature regulating valve core 13 (fully hot) and to the right to the maximum opening angle of the temperature regulating valve core 13 (fully cold), the positioning stud 21 pushes against the limiting rod of the adjusting ring 22. The other way to match the adjusting ring 22 with the positioning sleeve 20 is that the rear end of the positioning sleeve 20 is provided with a limiting member 201. The adjusting ring 22 is sleeved on the rear end of the positioning sleeve 20. The limiting rod of the adjusting ring 22 moves within the constraint range of the limiting member 201. When the control wheel 27 is turned to the left to the maximum opening angle of the temperature regulating structure (fully hot) and to the right to the maximum opening angle of the temperature regulating structure (fully cold), the limiting member 201 pushes against the limiting rod of the adjusting ring 22. In this embodiment, the limiting member 201 is an arc-shaped member that protrudes rearward from the rear end of the positioning sleeve 20. There are two types of arc-shaped members: one is a single arc-shaped member (see...). Figure 24The limiting rod of the adjusting ring 22 rotates in the space outside the arc-shaped component and stops after touching the arc-shaped component. This protects the time-delay valve core component 18 and the temperature-regulating valve core 13, preventing the user from violently or excessively rotating the two valve cores. When a single arc-shaped component is used, the rotation range of the limiting rod of the adjusting ring 22 is 90°-180°, preferably a semi-circular arc-shaped component. A second method using arc-shaped components involves using a pair of arc-shaped components (see...). Figure 25 The square post and square hole are symmetrically arranged on the rear end of the positioning sleeve 20. The two ends of the arc-shaped part form grooves for the rotation range of the adjusting ring 22 limiting rod. The cooperation between the square post and the square hole allows the rotating shaft push rod 53 to rotate, driving the rotating guide sleeve 45 to rotate together. The third gasket 52 is used to buffer the impact between the second retaining ring 532 and the rear wall of the inner cavity of the rotating guide sleeve 45, preventing damage or vibration. The third sealing ring 48 seals the gap between the push rod positioning sleeve 46 and the inner wall of the rotating guide sleeve 45, preventing water from entering the control component 19. The second gasket 50 prevents the first retaining ring 531 from impacting the rear wall of the push rod positioning sleeve 46 when it is pushed forward, thus providing a buffering effect.
[0050] The one-way valve component 16 includes a one-way valve sleeve 37, a first washer 38, a check valve component 39, an inlet water level line 40, an inlet water adjusting screw 42, a fourth sealing ring 41, a fifth sealing ring 43, and a sealing nut 44.

The outlet section of the valve hole is fitted onto the inner end of the sealing nut 44, and the outer circumference of the inner end of the sealing nut 44 is fitted with... A fourth sealing ring 41 is provided, and a fifth sealing ring 43 is fitted around the outer periphery of the middle section of the sealing nut 44. The outer periphery of the fourth sealing ring 41 is tightly attached to the inner wall of the outlet section of the one-way valve sleeve 37, and the outer periphery of the fifth sealing ring 43 is tightly attached to the wall surface of the valve body 9.

Hot water from the hot water inlet 64 enters the valve hole through the check valve component 39 from the inlet of the one-way valve sleeve 37, and then enters the first chamber from the hole at the outlet section of the one-way valve sleeve 37. Cold water from the cold inlet 65 enters the valve hole through the check valve component 39 from the inlet of the one-way valve sleeve 37, and then enters the second chamber from the hole at the outlet section of the one-way valve sleeve 37.
[0051] The flow-limiting component 12 includes a second washer 54, a pressure-reducing core 55, a sixth sealing ring 56, and a water outlet sealing screw 57.

A fourth drainage hole is formed on its side wall, connecting the drainage channel to the main chamber and acting as the inlet for the drainage channel. The pressure-reducing core 55 is installed at the outlet of the drainage channel. The second washer 54 is positioned on the drainage channel outside the pressure-reducing core 55, with its outer side abutting against the periphery of the hole communicating with the mixed water outlet 66. The second washer 54 and the sixth sealing ring 56 are used to increase sealing and prevent water leakage. Mixed water enters the drainage channel of the water outlet sealing screw 57 from the main chamber through the fourth drainage hole, and then flows out from the drainage channel outlet through the third chamber and the mixed water outlet 66 to the equipment requiring hot water.
[0052] Both the one-way valve component 16 and the flow-limiting component 12 are installed facing the wall. This arrangement facilitates replacement, maintenance, and disassembly. During maintenance, the water supply can be turned off using the one-way valve component 16 without needing to disconnect the main water pipe switch.

[0054] It also includes a concave baffle 3 and a convex baffle 4; the lower shell 1 of the protective sleeve has installation openings on its upper, lower, left, and right sides, with a lower arc-shaped opening on the bottom side of the installation opening, and slots on both sides of the installation hole; the lower side of the concave baffle 3 has an upper arc-shaped opening, and the lower side of the convex baffle 4 has an upper arc-shaped protrusion that matches the lower arc-shaped opening; during construction, the water pipe is connected to the hot water inlet 64, cold water inlet 65, and mixed water outlet 66 of the valve body 9 by sealing gaskets 8, nuts 7, and unions 6, respectively. The union 6 is located inside the installation opening. The concave baffle 3 is inserted into the slot of the installation opening with the union 6, and the union 6 is clamped in the space between the lower arc-shaped opening and the upper arc-shaped opening. The convex baffle 4 is inserted into the slot of the installation opening without the union 6, and the upper arc-shaped protrusion of the convex baffle 4 is embedded in the lower arc-shaped opening of the installation opening. The cooperation between the concave baffle 3, the convex baffle 4, and the slots can prevent debris such as cement from entering the protective sleeve shell during construction, and it is also easy to remove after construction.
[0055] A drain hole is provided on the lower side of the valve body 9. The drain hole is connected to the main chamber. A cover 11 is installed in the drain hole. The cover 11 seals the drain hole. A seventh sealing ring 10 is fitted on the outer periphery of the upper end of the cover 11. The outer periphery of the seventh sealing ring 10 abuts against the wall of the main chamber.
[0056] In this embodiment, the temperature control structure is an accessory of existing mature technology and is a commercially available product, therefore, no specific structural analysis is required. The temperature control structure includes a temperature control valve core 13, a flow guide block 14, and a water distribution valve core cover 15. The front end of the temperature control valve core 13 is connected to the first chamber and the second chamber respectively. The temperature control valve core 13 is provided with a ceramic plate for sealing or opening the holes at the connection between the temperature control valve core 13 and the two chambers. The rear end of the temperature control valve core 13 is provided with a third guide post with a gear. One end of the third guide post is connected to the ceramic plate, and the gear at the other end is engaged by a float sleeve 30. The float sleeve 30 is rotated by a rotating guide sleeve 45, thereby driving the third guide post to rotate so that the ceramic plate seals or opens the holes at the connection between the temperature control valve core 13 and the two chambers. The flow guide block 14 and the water distribution valve core cover 15 are sleeved on the outer periphery of the third guide post. The flow guide block 14 is clamped between the temperature control valve core 13 and the water distribution valve core cover 15, and the three form a whole and are located in the main chamber.

In this embodiment, a ninth sealing ring 23 is fitted onto the outer periphery of the front end of the positioning sleeve 20. When the positioning sleeve 20 is fitted onto the main chamber, the upper side of the ninth sealing ring 23 abuts against the inner wall of the main chamber. A fourth gasket 24 is fitted onto the inner side of the rear end of the positioning sleeve 20. The fourth gasket 24 is clamped between the rotating guide sleeve 45 and the positioning sleeve 20.
[0057] The working principle of this embodiment is as follows: Water enters the cold and hot inlets 64 of the valve body 9 into the cold check valve and the hot check valve, respectively, and then into the temperature regulating valve core 13. After mixing, it is ready to be drained. First, an instantaneous axial force is applied to the control wheel 27, causing the rotating shaft push rod 53 to move forward axially and push open the top rod 33 of the delay valve core component 18, so that it opens and drains the second chamber water 61 into the drainage tank 63. Due to the principle of water pressure difference, a negative pressure is generated. At this time, the float component 31 floats upward (physically speaking, in this product it floats backward), and the float gate is immediately opened. The first chamber of water 60 is discharged from the gate. The synchronously moving control wheel 27 is reset by the reset spring 49. The push rod 33 is reset by the action of the conical spring 32 and the float component 31. At the same time as the first chamber of water 60 is drained, the first chamber of water 60 is also injected into the second inner chamber from the third drain hole. The second chamber of water 61 is filled with water in a specified time. At the same time, according to the principles of fluid dynamics and water pressure difference, the water pressure of the first chamber of water 60 and the second chamber of water 61 is equal at this time. The gate of the float component 31 is closed and the valve core assembly is in the normally closed state. A process from opening to closing is perfectly completed.
[0058] When hot or cold water temperature adjustment is required, apply axial force to the control wheel 27 while simultaneously rotating the control handwheel left or right to adjust to the appropriate outlet water temperature. The temperature adjustment principle is as follows: by controlling the rotation of the temperature regulating valve core 13, the upper and lower ceramic discs inside the valve core are misaligned through friction to achieve mixing of hot and cold water. First, the control handwheel drives the control component 19 via the rotating shaft push rod 53. The rotating guide sleeve 45 on the control component 19 drives the delay valve core component 18. The float sleeve 30 on the delay valve core component 18 rotates, causing the temperature regulating valve core 13 to adjust the hot and cold water misalignment. Changing different misalignment angles achieves different mixed water temperatures. It can also be fully cold or fully hot. When the control handwheel is turned to the left to the maximum opening angle of the temperature regulating valve core 13, it is fully hot; when turned to the right to the maximum opening angle of the temperature regulating valve core 13, it is fully cold. The product also adds a full-open limit switch for the hot water end to prevent scalding. The limit switch is achieved through the adjusting ring 22 and the positioning stud 21. When the control handwheel is released, the water will be turned off according to the above process.
[0059] This embodiment has the following advantages:
[0060] 1) The same control handwheel can control the delay switch and adjust the temperature for both hot and cold water, as well as control the output of both hot and cold water.
[0061] 2) It adopts a standard and universal high-temperature ceramic temperature regulating valve core 13, which works in conjunction with the one-way valve at the water inlet to ensure that the water temperature is not fluctuating between hot and cold water, making it durable. At the same time, it is easy to maintain and replace.
[0062] 3) When adjusting the hot and cold water using the handwheel, there is an angle positioning function. The relevant accessories are the adjustment ring 22 and the positioning stud 21, which achieve the function of preventing scalding and ensuring safety.
[0063] 4) This valve core assembly is highly operable and interchangeable, and can be used in many products, such as concealed products, washbasin products, and other exposed products, such as vegetable basins.
[0064] 5) Most of the components of this valve core assembly are CNC machined, ensuring precise control and making assembly convenient and simple.
[0065] 6) This concealed product is equipped with a flow limiting component 12 at the water outlet, which can accurately control and meet the customer's water output per minute.
[0066] 7) The flow limiting component 12 and the one-way valve component 16 of this concealed product are all oriented towards the wall, which facilitates replacement, maintenance and disassembly. During maintenance, the power source can be turned off by the one-way valve component 16 without having to disconnect the main water pipe switch.
[0067] 8) The appearance of the panel 25 and the control handwheel of this concealed product can be changed at will, and the same product can meet the needs of different customers who purchase externally.
[0068] 9) During and after construction, it can be seen that this concealed product is equipped with a protective cover, which provides better protection for the product and prevents cement and other dirt from entering during construction. More specifically, the protective cover has raised baffles 4 and concave baffles 3 for water inlet and outlet, which ensures that no cement can enter the box during construction and that it is easy to remove after construction.
[0069] 10. The top and bottom covers of the protective case are prismatic in shape, reducing the panel's external dimensions by 25 and lowering the overall cost.
[0070] 11) The third drain hole and the float component 31 work together to create an up-and-down piston motion, thereby achieving automatic cleaning and anti-clogging effects. This product can also have small holes on the top rod 33 or the float to control the delay time and water volume, offering multiple options to suit the preferences of customers in different countries. Both methods can be customized according to customer requirements for time or water volume, simply changing the size of the delay tank or small hole for control.
[0071] 12) Because the float component 31 adopts a piston structure, the water output time and flow rate are stable each time. When used under high and low water pressures of 0.1 to 0.8 MPa, the time difference is not significant.
[0072] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the present utility model should be included in the patent scope of this case.
