Description

Control valve

The invention relates to a control valve.

In a cooling system, the flow of liquid is usually distributed through a control valve or a diverter valve. Taking the control valve as an example, it can be generally divided into two types: a rotary spool and a slide spool. Rotary spool valve means that the spool valve rotates around the shaft, and slide spool valve means that the spool valve reciprocates along the shaft. In addition, when operating the slide valve, the control valve can be operated in accordance with the principles of manual and electric. Among them, the manual type directly controls the position of the slide valve by a handle or a grip, and the electric type controls the position of the slide valve by a servo motor.

In general, the design of control valves needs to take into account leakage prevention performance, and because the valve is made into a ball head, the tightness of the valve and the valve body is better, so it can improve its leakage prevention performance. However, because the volume of the ball valve is larger than the perforation of the valve body, the ball valve cannot be directly inserted into the valve body of the control valve through the perforation. The valve body of the control valve must be disassembled into multiple shells to complete the control. Valve assembly. However, disassembling the valve body of the control valve into a plurality of shells will make the structural design of the control valve too complicated, which will cause inconvenience in manufacturing and assembly.

The invention aims to provide a control valve to simplify the structure of the valve body, so as to solve the problems of inconvenience in manufacturing and assembly of the control valve.

The control valve disclosed in one embodiment of the present invention includes a valve body and a valve. The valve is movably located in the receiving groove. Among them, the control valve has a lower limit flow rate, and the lower limit flow rate is greater than zero.

The control valve disclosed in another embodiment of the present invention includes a valve body and a valve. The valve body has an accommodation groove and at least one fluid inlet and at least one fluid outlet corresponding to the accommodation groove. The valve body has an inner wall surface surrounding the receiving groove. The valve has an outer wall surface and at least one main fluid passage. The valve is movably located in the containing groove, and an outer wall surface and an inner wall surface form a fluid bypass channel. The fluid main channel runs through the outer wall surface, and at least one inlet end and at least one outlet end of the fluid main channel correspond to at least one fluid inlet and at least one fluid outlet, respectively. Among them, the valve can move relative to the valve body to cause the valve to switch between the fluid main channel and change between a closed position and an open position. When the valve is in the closed position, at least one inlet end and at least one outlet end of the main fluid channel are shielded by the valve body, so that the fluid inlet communicates with the fluid outlet by the fluid side channel alone. When the valve is in the valve-opening position, at least one inlet end and at least one outlet end of the fluid main channel communicate with at least one fluid inlet and at least one fluid outlet, respectively, so that the fluid inlet communicates with the fluid outlet by the fluid main channel and the fluid side channel.

The control valve disclosed in another embodiment of the present invention includes a valve body and a valve. The valve body has at least one fluid inlet and at least one fluid outlet. The valve has at least one main fluid passage and at least one side fluid passage. The main fluid channel has at least one inlet end and at least one outlet end, and the cross-sectional area of the main fluid channel is larger than the cross-sectional area of the fluid side channel. The valve is movably mounted on the valve body and moves between a closed position and an open position. When the valve is in the closed position, the inlet end and outlet end of the fluid main channel are shielded by the valve body, so that the fluid inlet communicates with the fluid outlet by the fluid side channel. When the valve is in the valve-opening position, the inlet end and the outlet end of the fluid side channel are shielded by the valve body, and the fluid inlet is connected to the fluid outlet by the fluid main channel alone.

The control valve disclosed in another embodiment of the present invention includes a valve body and a valve. The valve body has an accommodating groove and an assembly port, a fluid inlet and a fluid outlet corresponding to the accommodating groove. The valve includes a penetrating portion and a columnar door portion connected to each other. The cylindrical door has a main fluid passage. An inlet end and an outlet end of the fluid main channel face the fluid inlet and the fluid outlet, respectively. The diameter of the columnar door portion is less than or equal to the diameter of the assembly port, so that the columnar door portion passes through the assembly port and the columnar door portion is movably located in the accommodation slot.

The control valve disclosed in another embodiment of the present invention includes a valve body, a valve, and at least a first sealing ring. The valve body is an integrally formed structure, and has an accommodation groove and an assembly port, a fluid inlet and a fluid outlet corresponding to the accommodation groove. The valve has a fluid main channel, and an inlet end and an outlet end of the fluid main channel face the fluid inlet and the fluid outlet, respectively. The valve is used to fit into the containing groove from the valve body through the assembly port. At least one first seal ring is sleeved on the valve and sandwiched between the valve body and the valve, so that the valve and the at least one first seal ring seal the assembly port.

According to the control valve of the above embodiment, the design of the fluid bypass valve enables the control valve to have a lower limit flow rate greater than zero when the valve is in the closed position. Therefore, when the cooling fluid is concentrated to the heat source with high heat generation, the heat source with low heat generation The corresponding control valve can also allow a small amount of cooling fluid to continuously flow to a low-heat-generation heat source to provide a minimum cooling effect for a low-heat-generation heat source.

Furthermore, because the lower limit flow of the control valve does not need to be precisely controlled at zero, the shape of the valve can be changed from a spherical shape to a cylindrical shape, and the diameter of the cylindrical door portion is smaller than the diameter of the assembly port. In this way, the assembler can directly insert the valve from the valve body's assembly port into the valve body's receiving groove, which allows the valve body to be integrated into a structure in design, thereby simplifying the manufacturing process and assembly of the control valve. program.

The control valve 10a of this embodiment includes a valve body 100a, a valve 200a, A driving element 300a and a plurality of sealing rings 400a.

The valve body 100a is, for example, a body-molded structure formed by injection molding or cutting. The valve body 100a has an accommodation groove 110a and an assembly port 120a corresponding to the accommodation groove 110a. The valve body 100a has an inner wall surface 130a surrounding the receiving groove 110a, a fluid inlet 140a and a fluid outlet 150a penetrating the inner wall surface 130a. That is, the assembly port 120a, the fluid inlet 140a, and the fluid outlet 150a all communicate with the accommodation groove 110a.

The valve 200a is rotatably located in the accommodating groove 110a and moves between a valve closing position (refer to FIG. 3 and FIG. 4) and a valve opening position (refer to FIG. 1 and FIG. 2). In detail, the valve 200a includes a penetrating portion 201a and a columnar door portion 202a connected to each other. The mounting portion 201a passes through the assembly port 120a, and the columnar door portion 202a is located in the accommodation groove 110a. These seal rings 400a are, for example, rubber rings, and are sleeved on the insertion portion 201a, so that the installation portion 201a and these seal rings 400a seal the assembly port 120a together. The driving element 300a is locked to the valve body 100a, for example, and is used to drive the valve 200a to rotate relative to the valve body 100a in a direction a around the axis A.

The cylindrical door portion 202a has an outer wall surface 210a and a fluid main passage 220a. The external shape of the fluid main channel 220a is, for example, a straight tube shape and penetrates the outer wall surface 210a. The fluid main channel 220a has an inlet end 221a and an outlet end 222a opposite to each other. When the valve 200a is in the open position (please refer to Figs. 1 and 2 for the time being), the inlet end 221a of the fluid main channel 220a and the outlet end 222a of the fluid main channel 220a are respectively aligned with the fluid inlet 140a and the valve body 100a of the valve body 100a. The fluid outlet 150a allows fluid to flow through the fluid main channel 220a from the fluid inlet 140a to the fluid outlet 150a in the direction F. When the valve 200a is in the closed position (please refer to Figs. 3 and 4), the inlet end 221a of the fluid main channel 220a and the outlet end 222a of the fluid main channel 220a are respectively connected to the fluid inlet 140a of the valve body 100a and the valve body 100a. Fluid outlet 150a is not heavy at all So that the fluid cannot flow through the fluid main channel 220a from the fluid inlet 140a to the fluid outlet 150a.

In this embodiment, the shape of the inlet end 221a of the fluid main channel 220a is the same as the shape of the fluid inlet 140a of the valve body 100a, or the size of the inlet end 221a of the fluid main channel 220a is the same as the fluid inlet 140a of the valve body 100a The dimensions are such that when the inlet end 221a of the fluid main channel 220a and the outlet end 222a of the fluid main channel 220a are respectively aligned with the fluid inlet 140a of the valve body 100a and the fluid outlet 150a of the valve body 100a, the fluid can flow more smoothly in the direction F The flow from the fluid inlet 140a to the fluid outlet 150a is not limited thereto. In other embodiments, the shape and size of the inlet end 221a of the fluid main channel 220a may be different from that of the valve body 100a on the premise that the minimum requirement for the fluid flowing from the fluid inlet 140a to the fluid outlet 150a in the direction F can be met The shape and size of the fluid inlet 140a.

The outer wall surface 210a and the inner wall surface 130a are loosely designed, and a fluid bypass channel 230a is formed between the outer wall surface 210a and the inner wall surface 130a. The flow rate per unit time of the fluid bypass channel 230a is smaller than the flow rate per unit time of the fluid main channel 220a. The fluid bypass channel 230a is an annular passage extending from the fluid inlet 140a to the fluid outlet 150a, so that the fluid inlet 140a can communicate with the fluid outlet 150a through the fluid bypass channel 230a regardless of whether the valve 200a is in the open or closed position. That is, when the valve 200a is in the open position, the fluid can flow from the fluid inlet 140a through the fluid main channel 220a and the fluid bypass channel 230a to the fluid outlet 150a, so that the control valve 10a has an upper limit flow rate when the valve is closed. . When the valve 200a is in the closed position, the fluid can still flow from the fluid inlet 140a to the fluid outlet 150a through the fluid bypass channel 230a alone, so that the control valve 10a has a lower limit flow rate when the valve is closed, and the lower limit flow rate is greater than zero.

Next, the liquid cooling system of a servo cabinet (not shown) will be used as an example to explain the control valve. The design reason for the lower limit flow of 10a is greater than zero. The liquid cooling system of the servo cabinet (not shown) includes a plurality of water cooling heads, a plurality of circulating flow tubes, a pump, and a plurality of control valves 10a. These water-cooled heads are, for example, arranged in different servers in a servo cabinet to perform heat exchange with different servers, or different heat sources are provided in the same server to perform heat exchange with different heat sources. These circulating flow tubes form cooling cycles between the water cooling heads and the pumps, respectively. These control valves 10a are installed on the circulating flow pipe to control the flow rate distributed by each heat source. For example, since a heat source with a higher calorific value requires a larger flow rate, but a heat source with a lower calorific value requires a smaller flow rate, the control valve 10a corresponding to the heat source with a high calorific value can be switched to the valve opening position. And the control valve 10a corresponding to the heat source with low heat generation is switched to the valve closing position to concentrate the cooling fluid to the heat source with high heat generation. In addition, since the control valve 10a corresponding to the low-calorific heat source still has a lower limit flow rate greater than zero when the valve is closed, when the cooling fluid is concentrated to the high-calorie heat source, the control valve corresponding to the low-calorie heat source 10a can also allow a small amount of cooling fluid to continuously flow to a low-calorie heat source to provide a minimum cooling effect for a low-calorie heat source.

Next, the control valve 10a will be discussed from another aspect. Because the lower limit flow rate of the control valve 10a does not need to be accurately controlled at zero, the shape of the valve 200a can be changed from spherical to cylindrical, and the diameter D1 of the cylindrical door 202a is smaller than the diameter D2 of the assembly port 120a. In this way, the assembling person can directly insert the cylindrical door portion 202a of the valve 200a into the accommodating groove 110a of the valve body 100a through the assembly port 120a of the valve body 100a to simplify the assembly process of the control valve 10a. In addition, because of this simplification of assembly, the valve body 100a can be changed into a one-piece structure, which further simplifies the manufacturing process and assembly process of the control valve 10a. The above-mentioned design of the diameter D1 of the columnar door portion 202a smaller than the diameter D2 of the assembly port 120a is not intended to limit the present invention. In other embodiments, the diameter of the columnar door portion may also be equal to the diameter of the assembly port.

In this embodiment, the number of the sealing rings is two, but it is not limited thereto. In other embodiments, the number of the sealing rings may be single or less than three. Furthermore, the embodiment uses an electric motor to drive the valve to rotate, but is not limited to this. In other embodiments, the valve can be controlled to rotate or slide by hydraulic pressure. In addition, the valve body may further have heat dissipation fins to enhance the heat dissipation effect of the valve body.

It should be noted that the fluid bypass channel 230a formed by the outer wall surface 210a of the valve 200a and the inner wall surface 130a of the valve body 100a is only one of the ways for the control valve 10a to achieve a lower limit flow rate greater than zero. .

When the valve is in the open position, the fluid may not pass through the fluid bypass channel, that is, it only passes through the fluid main channel. Please refer to FIG. 5 and FIG. 6. 5 is a schematic perspective view of a control valve according to a second embodiment of the present invention. FIG. 6 is a schematic cross-sectional view of FIG. 5.

The control valve 10b of this embodiment includes a valve body 100b, a valve 200b, a driving element 300b, two first sealing rings 400b, and two second sealing rings 450b.

The valve body 100b has an accommodation groove 110b and an assembly port 120b corresponding to the accommodation groove 110b. The valve body 100b has an inner wall surface 130b surrounding the receiving groove 110b, a fluid inlet 140b and a fluid outlet 150b penetrating the inner wall surface 130b. That is, the assembly port 120b, the fluid inlet 140b, and the fluid outlet 150b all communicate with the accommodation groove 110b.

The valve 200b is rotatably located in the receiving groove 110b. In detail, the valve 200b includes a penetrating portion 201b and a columnar door portion 202b connected to each other. The mounting portion 201b passes through the assembly port 120b, and the columnar door portion 202b is located in the accommodation groove 110b. The columnar door portion 202b has an outer wall surface 210b and a fluid main channel 220b. The external shape of the fluid main channel 220b is, for example, a straight tube shape and penetrates the outer wall surface 210b. The fluid main channel 220b has an inlet end 221b and an outlet end opposite to each other 222b. The two first seal rings 400b and the two second seal rings 450b are, for example, rubber rings. The two first sealing rings 400b are sleeved on the wearing portion 201b, so that the wearing portion 201b and the two first sealing rings 400b seal the assembly port 120b together. Two second sealing rings 450b are disposed on the cylindrical door portion 202b, and surround the inlet end 221b and the outlet end 222b of the fluid main channel 220b, respectively. The driving element 300b is locked to the valve body 100b, for example, and is used to drive the valve 200b to rotate relative to the valve body 100b.

Since the second and second sealing rings 450b surround the inlet end 221b and the outlet end 222b of the fluid main channel 220b respectively, so that when the valve 200b is in the open position, the fluid can only flow from the fluid inlet 140b through the fluid main channel 220b to the fluid outlet 150b. It does not flow through the above-mentioned fluid bypass channel 230a (as shown in FIG. 2).

The number of the inlet end and the outlet end of the fluid main channel is not limited to a single, please refer to FIG. 7 and FIG. 8.

The valve body 100c has an accommodation groove 110c and an assembly port 120c corresponding to the accommodation groove 110c. The valve body 100c has an inner wall surface 130c surrounding the receiving groove 110c, two fluid inlets 140c and a fluid outlet 150c penetrating the inner wall surface 130c. That is, the assembly port 120c, the two-fluid inlet 140c, and the fluid outlet 150c all communicate with the accommodation groove 110c. From the perspective shown in FIG. 7, the two-fluid inlet 140c is, for example, located on two opposite sides of the valve body 100c, and the fluid outlet 150c is, for example, located on the bottom surface of the valve body 100c.

The valve 200c is rotatably located in the receiving groove 110c. In detail, the valve 200c includes a penetrating portion 201c and a columnar door portion 202c connected to each other.

The cylindrical door portion 202c has an outer wall surface 210c and a fluid main passage 220c. The outer shape of the fluid main channel 220c is, for example, a T shape, and penetrates the outer wall surface 210c. The fluid main channel 220c has two inlet ends 221c and one outlet end 222c opposite to each other. The two inlet ends 221c correspond to the two-fluid inlet 140c, and the outlet end 222c corresponds to the fluid outlet 150c.

The two seal rings 400c are, for example, rubber rings. The two sealing rings 400c are sleeved on the wearing portion 201c, so that the wearing portion 201c and the two sealing rings 400c seal the assembly port 120c together. The driving element 300c is locked to the valve body 100c, for example, and is used to drive the valve 200c to rotate relative to the valve body 100c.

When the valve 200c is in the valve opening position (please refer to Figs. 7 and 8), the inlet end 221c of the fluid main channel 220c and the outlet end 222c of the fluid main channel 220c are respectively aligned with the fluid inlet 140c and the valve of the valve body 100c. The fluid outlet 150c of the body 100c allows fluid to flow through the fluid main channel 220c from the fluid inlet 140c to the fluid outlet 150c in the direction F.

The embodiment of FIG. 7 is a two-input single-output condition, but is not limited thereto. In other embodiments, the original entrance can be changed to an exit, and the original exit can be changed to an entrance, that is, a single-input two-output situation.

Please refer to FIGS. 20 to 22 again. 20 is a schematic plan view of a valve according to a thirteenth embodiment of the present invention. FIG. 21 is a schematic perspective view of the valve of FIG. 20 installed in a valve body and the valve in a closed state. FIG. 22 is a schematic diagram of valve opening degrees and flow curves of a circular valve port and an arrow-shaped valve port.

As shown in FIG. 20, in the valve 200m of this embodiment, the shapes of the opposite two valve ports 220m, 220m 'of the fluid main channel are arrow-shaped. Because the shape of the valve port 220m and the valve port 220m 'are the same, only the valve port 220m of the main fluid passage is taken as an example. Valve port of main fluid channel 220m, and has a first side 224m and a second side 225m. The width W4 of the first side 224m of the cross section is different from the width W3 of the second side 225m.

As shown in FIG. 21, the valve 200m of this embodiment is in a closed state, that is, the two valve ports 220m, 220m 'of the valve 200m are staggered from the two fluid inlets 140m of the valve body 100m. In addition, the valve 200m can be rotated about 90 degrees relative to the valve body 100m in the direction b, so that the valve 200m turns from the closed state to the open state. That is, the two valve ports 220m and 220m 'of the valve 200m are respectively aligned with the two fluid inlets 140m of the valve body 100m, so that fluid can flow from the two fluid inlets 140m of the valve body 100m to the fluid outlet 150m. Then, the valve 200m can be rotated in the direction c relative to the valve body 100m to change from the open state to the closed state.

The design of different widths is designed to make the 200m flow proportional control of the valve closer to linear.

By using a narrower arrow segment to ease the steepness of the steep segment, and through a wider arrow segment to increase the steepness of the gentle segment, the relationship curve between valve opening and fluid flow can be more Close to a linear situation (as shown by the solid line in Figure 22). Although this embodiment is compared with a circular valve port and an arrow-shaped valve port, the shape of the relationship curve between the valve opening degree and the fluid flow rate can be closer to a linear situation. The width W4 of the side 224m may be different from the width W3 of the second side 225m. Other implementation aspects will be described later.

From the perspective of FIG. 20, the valve port 220m and the first side 224m of the valve port 220m 'face the same rotation direction, which means that the arrows point in opposite directions. The purpose of the arrows pointing in the opposite direction is that during the rotation of the valve 200m in the direction b, the valve ports 220m and 220m 'of the fluid main channel are first aligned with the fluid inlet 140m by the arrow section (near the second side 225m), and the subsequent arrows The segment is then slowly aligned to the fluid inlet 140m. In this way, the steepness of the steep section can be eased by the narrower arrow section, and the steepness of the gentle section can be increased by the wider arrow section, so that the relationship between the valve opening angle and the fluid flow The curve can be closer to a linear situation.

According to the control valve of the above embodiment, the design of the fluid bypass valve enables the control valve to have a lower limit flow rate greater than zero when the valve is in the closed position. Therefore, when the cooling fluid is concentrated to the heat source with high heat generation, the heat source with low heat generation The corresponding control valve can also allow a small amount of cooling fluid to continuously flow to a low-heat-generation heat source to provide a minimum cooling effect for a low-heat-generation heat source.

Furthermore, because the lower limit flow of the control valve does not need to be precisely controlled at zero, the shape of the valve can be changed from a spherical shape to a cylindrical shape, and the diameter of the cylindrical door portion is smaller than the diameter of the assembly port. In this way, the assembler can directly insert the valve from the valve body's assembly port into the valve body's receiving groove, which allows the valve body to be integrated into a structure in design, thereby simplifying the manufacturing process and assembly of the control valve. program.

In addition, by making the widths of the two sides of the cross section of the main channel of the fluid different, the flow proportional control of the valve can be closer to linear. That is, the steepness is eased by the narrower arrow segment, and the steepness of the gentle segment is increased by the wider arrow segment, so that the relationship between the valve opening angle and the fluid flow can be closer to a linear situation.
