Description

Technical Field

[0001] This utility model relates to the field of mixing valve technology, and in particular to a proportionally adjustable mixing valve. Background Technology

[0002] Most water flow control valves used in daily life are single-valve structures, requiring one valve each for controlling the cold and hot water flows. During use, the opening of the two valves needs to be adjusted separately to obtain the appropriate water temperature. However, in adjusting the ratio of cold and hot water flow, the operator needs to rely on intuition to adjust the opening of the two valves. If the valve opening is adjusted too large or too small, the water temperature will be too cold or too hot, resulting in a significant time consumption for temperature adjustment. Therefore, a proportionally adjustable mixing valve was designed to solve this problem. Utility Model Content

[0003] To address the shortcomings of existing mixing valves, the purpose of this invention is to provide a proportionally adjustable mixing valve with advantages such as simultaneous adjustment of hot and cold water ratios and rapid water temperature regulation.

[0004] To achieve the above objectives, the present invention employs the following technical solution: a proportionally adjustable mixing valve, comprising a valve body, an adjusting knob, a proportional adjusting component, and an annular air bladder. The valve body has a cold water inlet and a hot water inlet on one side, and a mixing port on the other side. Inside the valve body, on one side, there is a first flow channel connecting the cold water inlet and the mixing port; inside the valve body, on the other side, there is a second flow channel connecting the hot water inlet and the mixing port. An annular air bladder is provided on the inner walls of both the first and second flow channels. A cylindrical cavity is located in the middle of the valve body, and the cylindrical cavity communicates with the annular air bladders on both sides through the flow channels. The proportional adjusting component is disposed within the cylindrical cavity and is used to control the expansion size of the annular air bladders on both sides. The adjusting knob is rotatably connected to the outside of the valve body to control the proportional adjusting component.

[0005] Preferably, the proportional adjustment assembly includes a piston, a piston rod, a threaded rod, and a filling fluid. The piston is axially slidably connected to the cylindrical cavity. A piston rod is fixedly connected to one side of the piston. The piston rod passes through the valve body and is axially slidably connected to it. A threaded rod is provided at the end of the piston rod extending out of the valve body. The filling fluid fills the entire annular airbag and the cylindrical cavity. The cylindrical cavity at the top of the piston is connected to the annular airbag in the first flow channel through a flow channel. The cylindrical cavity at the bottom of the piston is connected to the annular airbag in the second flow channel through a flow channel.

[0006] Preferably, the adjusting knob also has an internal threaded hole, and the threaded rod is inserted into and engaged with the internal threaded hole;

[0007] Preferably, the outer wall of the adjustment knob also has scale lines indicating hot and cold temperatures;

[0008] Preferably, the annular airbag is made of an elastic material;

[0009] Preferably, the filling fluid is an incompressible medium;

[0010] The beneficial effects of this utility model are: 1. By rotating the adjusting handwheel, the piston inside the valve body moves, causing the piston to drive the filling fluid to flow into or out of the annular air bladder and change the flow channel aperture, thereby achieving the purpose of synchronous adjustment of the hot and cold water ratio; 2. By observing the scale line on the outer wall of the adjusting handwheel, the hot and cold water ratio can be quickly observed, and the hot and cold water ratio can be finely adjusted by referring to the scale line during the adjustment process, thereby achieving the effect of rapid water temperature adjustment.

[0018] Please see Figures 1 to 4The embodiments of this utility model include:

[0019] A proportionally adjustable mixing valve includes a valve body 1, an adjusting knob 2, a proportional adjustment component 3, and an annular air bladder 4. The valve body 1 has a cold water inlet 11 and a hot water inlet 12 on one side, and a mixing port 13 on the other side. The valve body 1 has a first flow channel 14 inside one side, connecting the cold water inlet 11 and the mixing port 13, and a second flow channel 15 inside the other side, connecting the hot water inlet 12 and the mixing port 13. The inner walls of the first flow channel 14 and the second flow channel 15 are provided with annular air bladders 4. The valve body 1 has a cylindrical cavity 5 in the middle, which is connected to the annular air bladders 4 on both sides through the flow channel. The proportional adjustment component 3 is disposed in the cylindrical cavity 5 and is used to control the expansion size of the annular air bladders 4 on both sides. The adjusting knob 2 is rotatably connected to the outside of the valve body 1 to control the proportional adjustment component 3.

[0020] The proportional adjustment assembly 3 includes a piston 31, a piston rod 32, a threaded rod 33, and a filling fluid 34. The piston 31 is axially slidably connected to the cylindrical cavity 5. The piston rod 32 is fixedly connected to one side of the piston 31. The piston rod 32 passes through the valve body 1 and is axially slidably connected to it. The end of the piston rod 32 extending out of the valve body 1 is provided with a threaded rod 33. The filling fluid 34 fills the entire annular airbag 4 and the cylindrical cavity 5. The top cylindrical cavity 5 of the piston 31 is connected to the annular airbag 4 in the first flow channel 14 through a flow channel. The bottom cylindrical cavity 5 of the piston 31 is connected to the annular airbag 4 in the second flow channel 15 through a flow channel.

[0021] The adjustment knob 2 also has an internal threaded hole 21, and the threaded rod 33 is inserted into the internal threaded hole 21 and engaged.

[0022] The outer wall of the adjustment knob 2 also has scale lines 22 indicating hot and cold temperatures;

[0023] The annular airbag 4 is made of elastic material;

[0024] The filling fluid 34 is an incompressible medium;

[0025] With the above settings, its specific working principle in actual operation is as follows:

[0026] First, connect the hot water inlet 12 of valve body 1 to the hot water end through a pipe, connect the cold water inlet 11 to the cold water end through a pipe, and connect the mixing port 13 to the water-using end through a pipe.

[0027] When water is needed, open the hot water and cold water valves. When the scale line 22 on the outside of the adjusting knob 2 is in the middle, the cold water output is 1:1 with the hot water output. At this time, the mixing port 13 discharges warm water.

[0028] When a water temperature increase is required: Turn the adjustment knob 2 clockwise. During the rotation of the adjustment knob 2, the internally meshing screw moves axially. The screw drives the piston 31 to move into the cylindrical cavity 5 through the piston rod 32, which reduces the space of the cylindrical cavity 5 at the top of the piston 31. This forces the filling fluid 34 into the annular air bladder 4 in the first flow channel 14, causing the annular air bladder 4 in the first flow channel 14 to gradually expand, thereby compressing the aperture of the first flow channel 14 and reducing the cold water flow rate.

[0029] At the same time, the cylindrical cavity 5 at the bottom of the piston 31 expands, thereby absorbing the filling fluid 34 into the cylindrical cavity 5, causing the annular air bladder 4 in the second flow channel 15 to gradually shrink, thereby expanding the aperture of the second flow channel 15 and increasing the hot water flow. Throughout the process, the cold water flow decreases and the hot water flow increases, causing the water temperature at the mixing port 13 to rise.

[0030] When a water temperature reduction is required: Turn the adjustment knob 2 counterclockwise. During the rotation of the adjustment knob 2, the internally meshing lead screw moves axially. The lead screw drives the piston 31 to move out of the cylindrical cavity 5 through the piston rod 32, which expands the space of the cylindrical cavity 5 at the top of the piston 31. This allows the filling fluid 34 to be absorbed into the cylindrical cavity 5, causing the annular airbag 4 in the first flow channel 14 to gradually shrink, thereby expanding the aperture of the first flow channel 14 and increasing the cold water flow rate.

[0031] At the same time, the cylindrical cavity 5 at the bottom of the piston 31 shrinks, thereby squeezing the filling fluid 34 into the annular air bladder 4 in the second flow channel 15, causing the annular air bladder 4 in the second flow channel 15 to gradually expand, thereby reducing the aperture of the second flow channel 15 and reducing the hot water flow. Throughout the process, the cold water flow increases and the hot water flow decreases, causing the water temperature at the mixing port 13 to drop.

[0032] By observing the scale line 22 on the outer wall of the adjustment handwheel, the hot and cold water ratio can be quickly observed. During the adjustment process, the scale line 22 can be used as a reference to make fine adjustments to the hot and cold water ratio, thereby achieving the effect of quickly adjusting the water temperature.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
