The air control valve controls the flow of air flow by adjusting the sectional area of the ventilating duct, but the existing air control valve often has the problem of incomplete closing, so that the air control valve can still pass through trace air flow in a closing state, and further the air flow control precision is poor.
Disclosure of Invention
In order to overcome the above disadvantages, the present invention aims to provide a wind control valve, which can enhance the closing reliability of the wind control valve and ensure the sealing performance in the closing state.
In order to achieve the above purpose, the invention adopts the following technical scheme: a wind-controlled valve, comprising
The valve seat comprises a fixed shaft and an annular shell which are coaxially arranged, and a ventilation channel is defined between the annular shell and the fixed shaft;
the valve plate assembly is positioned in the ventilation channel and used for opening or closing the ventilation channel; the valve block assembly comprises a plurality of sector valve blocks distributed in a circumferential array, and two ends of any sector valve block are respectively and rotatably connected with the annular shell and the fixed shaft; and according to the clockwise direction of the annular shell, one side of any one fan-shaped valve plate facing the adjacent fan-shaped valve plate is provided with a sealing baffle plate;
the stop component is positioned on the inner side of the annular shell and comprises stop parts which are arranged in one-to-one correspondence with the fan-shaped valve plates, when the fan-shaped valve plates rotate to the closed positions, the fan-shaped valve plates can be abutted against the corresponding stop parts, and the sealing stop piece on any one fan-shaped valve plate can be abutted against the adjacent fan-shaped valve plate in a sealing way.
The wind control valve has the beneficial effects that:
the opening or closing of the ventilation channel is realized through the rotation of the fan-shaped valve plates, and when the ventilation air duct is opened, the opening size of the ventilation channel is regulated through regulating the rotation amplitude of the fan-shaped valve plates, so that the control of the airflow flow can be realized; the closed position of the fan-shaped valve plates can be limited through the arrangement of the stop component, meanwhile, the adjacent fan-shaped valve plates are in sealing butt joint through the sealing stop piece, air flow can be prevented from escaping from a gap between the two adjacent fan-shaped valve plates, the closing reliability of the air control valve is further enhanced, and the sealing performance of the air control valve in the closed state is guaranteed.
Further, the outer side surface of the fan-shaped valve plate comprises a first end surface, a second end surface, a first side surface, a second side surface, a windward side surface and a leeward side surface; the first end face faces the fixed shaft, the second end face faces the annular shell, the first side face faces the fan-shaped valve plates in the adjacent clockwise direction, the second side face faces the fan-shaped valve plates in the adjacent anticlockwise direction, the windward side face faces the air inlet of the ventilation channel, and the leeward side face faces the air outlet of the ventilation channel.
Further, the thickness dimension of the fan-shaped valve plate gradually decreases from the second side to the first side. The thickness dimension is the dimension between the windward side and the leeward side, and the thickness dimension is gradually reduced from the second side to the first side, so that the windward side close to the first side is thinner and is easier to blow by air flow, and the rotating direction of the fan-shaped valve plate when the ventilation channel is opened is further limited.
Further, when the fan-shaped valve plate is in a closed position, the windward side surface of the fan-shaped valve plate and the ventilation channel are obliquely arranged; and the sealing baffle is arranged on the first side surface of the fan-shaped valve plate, and one side of the sealing baffle, which faces the air inlet of the ventilation channel, protrudes out of the windward side surface of the fan-shaped valve plate. The windward side surface of the fan-shaped valve plate and the ventilation channel are obliquely arranged, so that the fan-shaped valve plate is easier to blow by air flow; the sealing baffle is arranged to protrude out of the windward side surface of the fan-shaped valve plate, so that the sealing baffle can shield the gap between two adjacent fan-shaped valve plates.
Furthermore, a mounting caulking groove is formed in one side, close to the first side surface, of the windward side surface of the fan-shaped valve plate; one end of the sealing baffle is fixedly embedded in the mounting caulking groove, and the other end extends out of the mounting caulking groove and is suspended. When the fan-shaped valve plates rotate to the closing position, the sealing baffle plates can synchronously rotate along with the fan-shaped valve plates, and one end of each sealing baffle plate, which is arranged in a suspending mode, can be abutted to the leeward side face of the adjacent fan-shaped valve plates, so that a gap between the two fan-shaped valve plates is shielded.
Further, when the fan-shaped valve plates are in the closed position, in the two adjacent fan-shaped valve plates, in the clockwise direction, the circle of the cross section of the windward side surface of the first fan-shaped valve plate coincides with the circle of the cross section of the leeward side surface of the second fan-shaped valve plate, that is, the windward side surface of one fan-shaped valve plate is coaxial with the leeward side surface of the other fan-shaped valve plate, and the shaft diameters are the same. Because the sealing baffle is the windward side of the fan-shaped valve block that the protrusion corresponds, when the circle that the windward side cross section of first fan-shaped valve block is located and the circle coincidence of leeward side cross section of second fan-shaped valve block are located, the sealing baffle can receive the extrusion of second fan-shaped valve block leeward side, and then can seal to press on second fan-shaped valve block leeward side, and then has avoided the air current to escape from the clearance between two fan-shaped valve blocks.
Furthermore, the stop part comprises a windward stop seat and a leeward stop seat which are matched for use, and the windward stop seat and the leeward stop seat are arranged in a staggered manner along the circumferential direction and the axial direction of the inner side wall of the annular shell; the fan-shaped valve plate is positioned between the windward stop seat and the leeward stop seat, and when the fan-shaped valve plate is positioned at the closing position, the windward side surface of the fan-shaped valve plate can be abutted on the windward stop seat, and the leeward side surface of the fan-shaped valve plate can be abutted on the leeward stop seat. The windward side and the leeward side of the fan-shaped valve plate can be stopped simultaneously by arranging the windward stop seat and the leeward stop seat, so that the closing position of the fan-shaped valve plate can be limited, and the problem of incomplete closing is avoided.
Furthermore, a cushion pad is arranged on one side of the windward stop seat, which faces the fan-shaped valve plate, of the leeward stop seat. The buffer pad can buffer the acting force of the fan-shaped valve plate stop on the windward stop seat and the leeward stop seat, thereby playing a silencing role and avoiding surface damage caused by rigid impact.
Furthermore, the two ends of the fan-shaped valve plate are respectively provided with a first shaft sleeve and a second shaft sleeve, and the straight lines of the first shaft sleeve and the second shaft sleeve are coincident and pass through the axle center of the fixed shaft. The inner side wall of the annular shell is provided with a first shaft which is arranged in one-to-one correspondence with the fan-shaped valve plates and can be inserted into the first shaft sleeve, and the outer side wall of the fixed shaft is provided with a second shaft which is arranged in one-to-one correspondence with the fan-shaped valve plates and can be inserted into the second shaft sleeve.

The ventilation channel is opened or closed by the rotation of the fan-shaped valve plates 21, and the opening size of the ventilation channel is adjusted by adjusting the rotation amplitude of the fan-shaped valve plates 21 in the opening process of the ventilation air channel, so that the air flow can be controlled; the closed position of the fan-shaped valve plates 21 can be limited through the arrangement of the stop component 3, meanwhile, the adjacent fan-shaped valve plates 21 are in sealing butt joint through the sealing baffle 4, air flow can be prevented from escaping from a gap between the two adjacent fan-shaped valve plates 21, the closing reliability of the wind control valve is further enhanced, and the sealing performance of the wind control valve in the closed state is guaranteed.
For convenience of the following description, the respective outer side surfaces of the segment valve plates 21 are defined. Specifically, referring to fig. 3-6, the outer side surface of the fan blade 21 includes a first end surface 211, a second end surface 212, a first side surface 213, a second side surface 214, a windward side surface 215, and a leeward side surface 216. The first end surface 211 faces the fixed shaft 11 and is adapted to the shape of the fixed shaft 11. The second end face 212 faces the annular housing 12 and is adapted to the shape of the annular housing 12. The first side surface 213 and the second side surface 214 are respectively located at two sides of the first end surface 211 and are respectively used for connecting the first end surface 211 and the second end surface 212; and the first side 213 faces the adjacent sector plate 21 in the clockwise direction and the second side 214 faces the adjacent sector plate 21 in the counterclockwise direction. The windward side 215 faces the air inlet of the ventilation channel and the leeward side 216 faces the air outlet of the ventilation channel. The rotation axis of the fan-shaped valve plate 21 is a line connecting the center points of the first end surface 211 and the second end surface 212, and when the fan-shaped valve plate 21 is opened, the fan-shaped valve plate 21 rotates anticlockwise along the rotation axis, and when the fan-shaped valve plate 21 is closed, the fan-shaped valve plate rotates clockwise along the rotation axis.
In some embodiments, when the fan blade 21 is in the closed position, the windward side 215 of the fan blade 21 is inclined with the ventilation channel, so that when the airflow blows to the fan blade 21 along the ventilation channel, an inclined angle of not 90 ° can be formed between the airflow direction and the fan blade 21 due to the inclination of the fan blade 21, and further the rotation of the fan blade 21 is facilitated, so as to realize the opening of the ventilation channel.
Further, referring to fig. 5 to 6, the thickness dimension of the segment valve plate 21 gradually decreases from the second side 214 toward the first side 213. It should be noted that the thickness dimension refers to a dimension between the windward side 215 and the leeward side 216, and the thickness dimension is set to gradually decrease from the second side 214 to the first side 213, so that the windward side 215 near the first side 213 is thinner and is more easily blown by the air flow, thereby defining the rotation direction of the fan blade 21 when the ventilation channel is opened.
In some embodiments, referring to fig. 3-4, the sealing flap 4 is disposed on the first side 213 of the fan blade 21, and the length of the sealing flap is adapted to the length of the first side 213 to ensure that the sealing flap 4 completely covers the gap between the two fan blades 21. Further, referring to fig. 5-6, the sealing flap 4 projects towards the windward side 215 of the fan blade 21 on the side facing the air inlet of the ventilation channel. The sealing baffle 4 is arranged to protrude out of the windward side 215 of the fan-shaped valve plate 21, so that the sealing baffle 4 can cover the gap between two adjacent fan-shaped valve plates 21.
In some embodiments, referring to fig. 6, a mounting recess 2151 is formed in the windward side 215 of the fan blade 21 near the first side 213 thereof. One end of the sealing baffle 4 is fixedly embedded in the mounting embedded groove 2151, and the other end extends out of the mounting embedded groove 2151 and is suspended. When the fan-shaped valve plates 21 rotate to the closed position, the sealing baffle plates 4 can synchronously rotate along with the fan-shaped valve plates, and one end of the sealing baffle plates 4 which are suspended can be abutted to the leeward side surface 216 of the adjacent fan-shaped valve plates 21, so that a gap between the two fan-shaped valve plates 21 is shielded. When the fan-shaped valve plate 21 rotates to the opening position, the suspended end of the sealing baffle 4 may bend towards the leeward side 216 of the fan-shaped valve plate 21 due to the air flow, the sealing baffle 4 may press against the first side 213, in some embodiments, the junction between the first side 213 and the mounting groove 2151 may be designed as a rounded structure, so that the sealing baffle 4 may better fit on the first side 213 when bending towards the leeward side 216 of the fan-shaped valve plate 21.
In some embodiments, referring to fig. 5, when the fan blades 21 are in the closed position, in the clockwise direction of the annular housing 12, the circle on the cross section of the windward side 215 of the first fan blade 21 coincides with the circle on the cross section of the leeward side 216 of the second fan blade 21, that is, the windward side 215 of one fan blade 21 is coaxial with the leeward side 216 of the other fan blade 21 and has the same shaft diameter. Because the sealing baffle 4 protrudes out of the windward side 215 of the corresponding fan-shaped valve plate 21, when the circle of the cross section of the windward side 215 of the first fan-shaped valve plate 21 is overlapped with the circle of the cross section of the leeward side 216 of the second fan-shaped valve plate 21, the sealing baffle 4 is extruded by the leeward side 216 of the second fan-shaped valve plate 21, and can be pressed against the leeward side 216 of the second fan-shaped valve plate 21 in a sealing manner, so that the sealing effect is further enhanced, and the air flow is prevented from escaping from the gap between the two fan-shaped valve plates 21.
