The terms "head" and "tail" are hereinafter referred to in relation to the direction of the air flow, and are defined as "head" upstream and "tail" downstream in the direction of the air flow.
As shown in fig. 1 and 2, the present invention provides a gas flow rate adjusting device, which can be applied to various occasions where the adjustment of the gas flow rate is required. In an exemplary embodiment, the gas flow regulating device includes a valve body 3 and a valve core 2, the valve core 2 is disposed in the valve body 3 and forms a gas flow channel with an inner sidewall of the valve body 3, a tail end of the valve core 2 along a gas flow direction is provided with a first flow guiding portion 22, the first flow guiding portion 22 is configured to guide the gas flow to flow in a gas outlet direction, and a flow guiding surface of the first flow guiding portion 22 and an outer sidewall of the valve core 2 are smoothly transited to form a streamline structure.
In the gas flow rate adjustment device according to the embodiment of the present invention, after entering the valve body 3, the gas flows along the gas flow path between the valve body 3 and the valve element 2, and when flowing to the tail region of the valve element 2, the gas can flow in the gas outlet direction under the guidance of the first guide portion 22. Moreover, since the flow guiding surface of the first flow guiding portion 22 and the side wall 21 of the valve core 2 are in smooth transition, when the gas flows through the transition region of the first flow guiding portion 22 and the side wall 21, the gas still has a specific flow direction, the gas flow structure is reasonable, and finally the gas flows out of the valve body under the guidance of the first flow guiding portion 22. Thus, the air flow is not easy to form vortex when flowing to the tail part of the valve core 2, the turbulence of the air flow field is avoided, and the noise generated when the air passes through the inside of the flow regulating device can be reduced. Particularly, when the valve element 2 is at a low opening degree, the large noise is easier to generate due to the small gas flow rate, so that the problem of large noise when the valve element 2 is at a low opening degree can be well solved by the embodiment.
Preferably, the flow guiding surface of the first flow guiding portion 22 has a streamline structure. The flow guide surface of the streamline structure can gradually change the flow direction of the gas, so that the gas forms a stream and flows towards the air outlet, the scattered flow of part of the gas towards different directions is prevented, the gas flow is prevented from being disturbed, the gas flow resistance is reduced, the energy loss is reduced, the stable gas flow structure is formed, and the gas flow noise is reduced.
In one embodiment, the first flow guide 22 has an opening at the central region of the valve spool 2, and the valve spool 2 may be designed in a structure having a cavity. The first diversion part 22 is annularly arranged at the tail part of the valve core 2 along the circumferential region of the valve core 2, so that air flow from the side part of the valve core 2 along the whole circumferential direction can flow towards the air outlet direction under the action of the first diversion part 22. When the airflow is large, the radial width of the first diversion part 22 needs to be increased, and the size of the opening needs to be correspondingly reduced so as to prevent the airflow from flowing into the opening; accordingly, when the air flow is small, the radial width of the first flow guiding portion 22 can be appropriately reduced, and the opening size can be correspondingly increased. The radial width of the first guiding portion 22 needs to be designed according to the size of the air flow, so that the air flow does not enter the opening when the air flow is separated from the first guiding portion 22, and therefore vortex air flow is prevented from being generated to cause turbulence of the air flow field.
Preferably, the diversion surface of the first diversion portion 22 is an arc surface, an inclined surface, an S-shaped surface, or the like. Further, a smaller adjusting part may be added at the free end of the first guiding part 22 to fine tune the direction or size of the air flow, and the adjusting part preferably guides the air flow to flow toward the air outlet 4. For example, the free ends of the cambered surface, the inclined surface and the S-shaped surface are provided with arc structures for adjusting the gas flow direction. Regardless of the shape of the first guiding portion 22, the first guiding portion 22 should smoothly transition with the side wall of the valve body 3, so as to avoid obvious connection portions, corners and sharp angles between adjacent surfaces.
When the flow guiding surface of the first flow guiding portion 22 is an arc surface, the arc surface is preferably adopted, so that the processing is convenient, the size is easy to control, and the distribution of the gas flow field in the valve body 3 is ensured. For example, referring to fig. 2, the circular arc-shaped guide surface may be concave toward the inside of the spool 2 or convex toward the outside of the spool 2 as viewed in the longitudinal section of the spool 2.
In another preferred embodiment, as shown in fig. 1, the first diversion portion 22 seals the tail end of the valve body 3 integrally, and the valve body 3 may be designed to be a solid structure or a structure with a cavity, and the first diversion portion 22 adopts a streamline structure. The structure can reliably guide the air flow by utilizing the closed tail end of the valve body 3 without considering the air flow size, so that the air flow smoothly transits from the air flow channel at the side part of the valve core 2 to the air flow channel at the tail part of the valve core 2, and then flows towards the air outlet 4. When the valve core 2 moves in the valve body 3 along the air flow direction to adjust the air flow, the air flow can have a stable flow field at the tail part of the valve body 3 no matter the air flow is throttled, so that the air flow noise in the valve body 3 is reduced.
Preferably, as shown in fig. 1, the diversion surface of the first diversion portion 22 integrally forms an arc surface, and the arc diversion surface is an arc surface integrally formed to be convex toward the air outlet 4, and the arc diversion surface is in smooth transition with the side wall of the valve core 2. The first diversion part 22 with the arc diversion surface seals the whole tail part of the valve core 2, when the airflow moves to the tail part area along the side wall of the valve core 2, the airflow flows along the smooth transition area of the first diversion part 22 and the side wall of the valve core 2, then gradually flows along the arc diversion surface under the diversion effect of the first diversion part 22, gradually moves away from the diversion surface in the process of moving towards the center area of the arc diversion surface, and finally moves towards the direction of the air outlet 4. More preferably, the arc-shaped diversion surface may be a circular arc-shaped diversion surface, and the first diversion part 22 with the circular arc-shaped diversion surface covers the tail part of the valve core 2.
The embodiment can shorten the tail length of the valve core 2, reserve a sufficient space for the rear part of the valve body 3 to install other parts, and the reduction of the tail length of the valve core 2 can increase the flow area of the corresponding position of the tail of the valve core 2, so that the flow speed can be properly reduced to reduce the air flow noise.
Preferably, as shown in fig. 2, the valve body 3 is provided with an air outlet 4, and the air outlet 4 can be connected with an air outlet pipe so as to guide out the air flow in the valve body 3. The first diversion part 22 extends towards the direction of the air outlet 4 away from one end connected with the side wall of the valve core 2, and the diversion surface of the first diversion part 22 is a cambered surface which is concave towards the inside of the valve core 2 or convex towards the outside of the valve core 2. With this structure, the first flow guiding portion 22 may be closed at an end near the air outlet 4 to prevent vortex from being generated when the air flow is large. This embodiment can lengthen the flow guiding path of the first flow guiding portion 22 to the gas, which is advantageous to flow the gas in a more concentrated stream to the gas outlet 4, so as to reduce the energy loss of the gas.
If the first flow guiding portion 22 is extended to a position close to the gas outlet 4, so that the flow area of the gas is reduced, the flow rate is increased, and noise when the gas flows to the tail end of the valve element 2 may be increased. Therefore, in design, the length of the first diversion part 22 extending towards the air outlet 4 can be reasonably controlled so as to achieve the effect of reducing noise.
Of course, in the embodiment in which the first flow guiding portion 22 extends away from the end connected to the side wall of the valve element 2 toward the air outlet 4, the flow guiding surface of the first flow guiding portion 22 may be designed as an inclined surface, an S-shaped surface, or the like, in addition to the cambered surface.
On the basis of the above embodiment, as shown in fig. 1 and 2, the valve body 3 is provided with the air inlet 1, and preferably, the air inlet 1 and the air outlet 4 are opposite to each other. The air inlet 1 is opposite to the head end of the valve core 2 along the air flow direction, a second flow guide part 6 is arranged on one side of the air inlet 1, which is positioned in the valve body 3, a conical air flow channel is formed between the second flow guide part 6 and the side wall 21 of the valve core 2, and the valve core 2 can move along the air flow direction to change the flow area of the conical air flow channel.
For example, the air inlet 1 is circular, the second flow guiding portion 6 is a circular flow guiding ring, both the flow guiding ring and the side wall 21 of the valve core 2 can be designed to be in a conical structure, and the flow guiding ring forms a horn shape, so that a conical airflow channel is formed between the flow guiding ring and the side wall 21 of the valve core 2. An intake pipe may be connected at the intake port 1 to introduce outside air into the interior of the valve body 3. The air outlet section is annular, so that the peripheral annular air outlet can be realized, and the air outlet is non-directional, so that the air outlet is more uniform than a vane type butterfly valve, and the noise can be reduced.
In order to enable the valve core 2 to stably move relative to the valve body 3, a guide structure is arranged on the valve body 3, a fixing part 5 is arranged on the valve core 2, one end of the fixing part 5 is connected with the valve core 2, and the other end of the fixing part is matched with the guide structure so as to enable the valve core 2 to move relative to the valve body 3 along the air flow direction. For driving the valve body 2 to move, a driving member may be coupled to the fixing member 5 to drive the valve body 2 to move in the air flow direction by the driving member, thereby adjusting the flow area of the air flow passage. For example, the driving member may be a linear driving member such as a linear motor, a cylinder, or a hydraulic cylinder. The driving means may be located inside or outside the valve body 3.
The air flow regulating channel of the air flow regulating mechanism is designed to be conical, when the valve core 2 moves for preset displacement, the width change of the air flow regulating channel is smaller than the movement displacement of the valve core 2, so that the flow area change quantity of the air flow regulating channel is reduced, the air flow can be regulated in a micro-quantity more accurately, the accuracy of the air flow regulation can be improved, and the corresponding relation between the movement displacement of the valve core 2 and the air flow is easier to control. When the gas flow rate adjustment means is at a low opening, the gas flow rate can be adjusted more accurately.
Preferably, the flow guiding surface of the second flow guiding portion 6 is consistent with the taper of the side wall 21 of the valve core 2, that is, the width of the air flow adjusting channel for adjusting the air flow is consistent throughout, so that the width of the air flow adjusting channel can be linearly changed when the valve core 2 moves, thereby achieving the purpose of linearly adjusting the air flow. Because the adjustment amplitude of the valve core 2 is in linear relation with the flow area change amplitude of the air flow adjustment channel, when the air flow adjustment device is at a low opening degree, the air flow adjustment is more accurate. In addition, the air flow regulating channel is regular in shape, so that noise when air flows through the channel can be reduced, and throttling noise when the valve core 2 is at a low opening degree can be greatly improved.
The taper of the airflow regulating channel can be designed according to actual demands, the smaller the taper of the tapered airflow channel is, the smaller the width variation of the airflow regulating channel is when the valve core 2 moves for preset displacement, the smaller the flow area variation of the airflow regulating channel is, and the more accurate the regulation of the airflow is. Conversely, the larger the taper of the tapered air flow channel, the larger the width variation of the air flow regulating channel when the valve core 2 moves for a preset displacement, the larger the flow area variation of the air flow channel, and the lower the regulating precision of the air flow.
By adjusting the taper of the side wall 21 of the spool 2, the rate of change of the flow area corresponding to the unit horizontal stroke of the spool 2 can be changed. Under the condition that the length is allowed, the larger horizontal stroke can be realized and the smaller flow cross section is changed, the gas flow is regulated more accurately, and the problem that the butterfly valve is controlled to be rough when the opening degree is small is solved. Meanwhile, the conical valve is balanced in stress and does not generate abnormal shake.
The free end of the second deflector 6 (e.g. deflector ring) extends to a position close to the inner wall of the valve body 3 to better deflect the gas entering the valve body 3.
In fact, after moving along the second flow guiding portion 6 of a certain length, the gas can be guided into a smooth flow, and enter a laminar state, and can flow basically in the direction of the previous flow guiding even if it is no longer guided by the second flow guiding portion 6, and the optimization of the flow guiding effect is limited even if the length of the second flow guiding portion 6 is increased. Therefore, the second guiding part 6 (such as a guiding ring) can meet the guiding requirement only by covering the length section of the head end of the side wall 21 of the valve core 2, so that the material is saved, the processing is convenient, and the space is saved.
Further, still referring to fig. 1, the head end of the spool 2 in the air flow direction has a streamline structure, and the head end of the spool 2 smoothly transitions with the side wall 21. Preferably, the front end of the valve core 2 in the air flow direction is an arc surface. In combination with the shape design of the various parts of the valve spool 2, the valve spool 2 is preferably integrally formed as a fin-shaped cone valve, as shown in fig. 1.
The working principle of the gas flow regulating device of the present invention will be explained below with reference to the embodiment shown in fig. 1.
After entering the valve body 3 from the air inlet 1 along the arrow A, the air flows from left to right, sequentially passes through an annular air flow channel formed by the conical valve core 2 and the second flow guide part 6, an air flow channel formed by the side wall 21 of the valve core 2 and the valve body 3, and a through flow area formed by the tail end of the valve core 2 and the valve body 3, and then flows out from the air outlet 4 on the right side of the valve body 3 along the arrow B.
When the gas flow is required to be regulated, the gas flow can be regulated in real time in the process of gas flow, and the control part controls the driving part to enable the valve core 2 to move back and forth along the gas flow direction so as to change the flow area of the gas flow regulating channel, thereby changing the gas flow resistance and regulating the gas flow. A flow meter may be provided in the gas line to keep the valve spool 2 in the current position after the gas flow is adjusted to the target value.
In the gas flow rate adjusting process, when the valve element 2 moves toward the direction (leftward) approaching the second flow guiding portion 6, the distance between the valve element 2 and the second flow guiding portion 6 decreases, the flow area of the gas flow adjusting passage decreases, the gas flow resistance increases, and the gas flow rate correspondingly decreases. When the valve element 2 moves in a direction away from the second flow guiding portion 6 (rightward), the distance between the valve element 2 and the second flow guiding portion 6 increases, the flow area of the air flow regulating passage increases, the air flow resistance decreases, and the air flow rate correspondingly increases.
From the above description of the embodiments, it can be seen that the gas flow rate adjustment mechanism of the present invention has at least the following advantages:
(1) The tail part of the valve core 2 is provided with the first diversion part 22 which is in smooth transition with the side wall 21, the head end of the valve core 2 is designed into a streamline structure, the circumferential annular air outlet can be realized, and the shape of an air flow regulating channel is more regular, so that the air flow organization is more reasonable when air flows into the valve body 3, the air flow disorder is prevented, and the effect of reducing the working noise of the air flow regulating device is achieved.
(2) The valve core 2 and the second guide part 6 at the inner side of the air inlet 1 form a conical air flow regulating channel, so that the linearity of air flow regulation can be improved, and the air flow regulation is more accurate.
Therefore, the gas flow regulating device can be suitable for occasions with higher requirements on regulating precision and noise control.
The invention further provides an air duct assembly, which comprises the air flow adjusting device of each embodiment, wherein the air flow adjusting device is arranged in the air duct and is used for adjusting the flow of air in various air ducts. The gas flow regulating device can accurately regulate the gas flow in the air duct, and the generated noise is small when the gas flows through the gas flow regulating device.
Finally, the invention also provides an air conditioner comprising the air flow regulating device or the air duct assembly. The air flow regulating device can be used for regulating the air supply amount of the air conditioner, and can accurately regulate the air supply amount by controlling the movement of the valve core 2, so that the requirements of the air supply amount under different environment temperatures are met, and the comfort level feeling of a user is improved; and because the noise of the gas flow regulating device in the working process is smaller, the noise of the air conditioner in the working process can be reduced, the interference to a user is reduced, and the quality of the air conditioner is improved.
