The air valves of the prior art are not suitable for connecting with the floor cavities, it is inconvenient to control the air flow size circumferentially, the installation operation is relatively complex, and the floor area is relatively large. Summary of the Invention

[0003] The invention object of the present invention is to overcome the deficiencies of the prior art, and provide a pluggable circumferential control type energy-saving air flow valve and a using method thereof.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A pluggable circumferential control type energy-saving air flow valve includes a closing assembly, a fixed sleeve, a pipe sleeve and an upper circular torsion plate that can be sleeved on the fixed sleeve; the closing assembly includes a lower circular torsion plate, an annular plate, M quadrilateral blades with triangular front ends arranged from top to bottom, and a circular rail limiting shell plate, M≥3; the rail limiting shell plate includes a circular plate and a circular surrounding plate arranged on the outer edge of the circular plate, and the outer edge of the lower circular torsion plate is fixedly connected with the circular surrounding plate; the lower part of the upper circular torsion plate is clamped with the inner edge of the lower circular torsion plate, and two horizontally extending fixing strips are respectively arranged on the lower left part and the lower right part of the outer peripheral surface of the fixed sleeve, and the two fixing strips are located between the upper circular torsion plate and the lower circular torsion plate, and the upper surface of the annular plate is fixedly connected with the two fixing strips, and the pipe sleeve is clamped with the fixed sleeve; M uniformly distributed lower protrusions are arranged on the edge of the lower surface of the annular plate, a horizontally extending opening chute is arranged at the rear part of the quadrilateral blade, and a cylindrical protrusion is arranged on the lower surface of the quadrilateral blade, and the cylindrical protrusion is close to the inner end of the opening chute; the M lower protrusions respectively extend into the opening chutes of the M quadrilateral blades; M long strip-shaped sliding holes are arranged on the rail limiting shell plate in an annular arrangement along the inner edge of the rail limiting shell plate, and the M cylindrical protrusions respectively extend into the M long strip-shaped sliding holes; the diameter of the inner edge of the lower circular torsion plate is larger than the diameter of the inner edge of the annular plate, the diameter of the inner edge of the annular plate is the same as the diameter of the inner edge of the rail limiting shell plate, and the angle of the front end of the quadrilateral blade is The front ends of the respective quadrilateral blades can form a circular structure for closing the lower end of the fixed sleeve. When the upper circular torsion plate is rotated clockwise, the respective quadrilateral blades gradually rotate and radially move outwards and separate.

[0006] There are N floor cavities in the floor of a room equipped with an air-borne energy radiation air conditioner. Open the cover plate of the floor cavity, fixedly connect the two fixing strips of the present invention to the lower surface of the cover plate, so that the upper part of the fixing sleeve and the two rectangular blocks are exposed outside the upper surface of the cover plate, and make the sealing ring provided on the fixing hole of the cover plate be hermetically connected to the fixing sleeve and the two rectangular blocks, and cover the cover plate on the floor cavity; the two outward-extending fixing strips reduce the floor area.

[0007] Insert the two outer protrusions of the pipe sleeve downward into the two opening grooves of the corresponding fixing sleeve, and rotate the pipe sleeve so that the two outer protrusions are stuck to the bottom ends of the two opening grooves of the fixing sleeve.

[0008] The pipe sleeve is connected to the air-conditioning hose of the air-borne energy radiation air conditioner, and the air-conditioning hose is connected to the cavity of the radiation plate of the air-borne energy radiation air conditioner.

[0009] When it is necessary to use the radiation plate for refrigeration or heating, rotate the upper circular torsion plate corresponding to the radiation plate clockwise. The upper circular torsion plate drives the lower circular torsion plate and the slide rail limiting shell plate to rotate clockwise. M long strip-shaped sliding holes respectively drive M quadrilateral blades to rotate clockwise through M cylindrical protrusions. At the same time, the opening sliding grooves of the quadrilateral blades drive the quadrilateral blades to slide along the corresponding lower protrusions. The quadrilateral blades rotate and move radially outward, and the opening degree of the energy-saving air flow valve gradually increases.

[0010] When the upper circular torsion plate cannot continue to rotate clockwise, the M quadrilateral blades move into the cavity formed by the lower circular torsion plate and the slide rail limiting shell plate, the energy-saving air flow valve is completely opened, and the cold air or hot air stored in the floor cavity flows out, and the radiation plate performs temperature radiation.

[0011] When it is not necessary to use the radiation plate for refrigeration or heating, rotate the upper circular torsion plate corresponding to the radiation plate counterclockwise. The quadrilateral blades rotate and move radially inward. When the upper circular torsion plate cannot continue to rotate counterclockwise, the front parts of the M quadrilateral blades form a circular structure, and the circular structure closes the lower end of the fixing sleeve, the energy-saving air flow valve is closed, and the radiation plate stops temperature radiation.

[0012] The present invention can connect the upper circular torsion plate and the lower circular torsion plate together through insertion and rotation operations. By rotating the upper circular torsion plate, it drives each quadrilateral blade to rotate and move radially, realizing the functions of controlling the opening and closing of the energy-saving air flow valve and adjusting the valve opening degree; therefore, the present invention has the characteristics that the operation of controlling the opening and closing of the energy-saving air flow valve and adjusting the valve opening degree is simpler, the floor area occupied by the valve is small, it is convenient to control the air flow size circumferentially, the rotation angle is small, the stroke is short, and the installation efficiency is high.

[0013] Preferably, two rectangular notches are provided on the lower edge of the upper circular torsion plate, and two rectangular blocks are provided on the inner edge of the lower circular torsion plate; the two rectangular blocks can be respectively connected in cooperation with the two rectangular notches. The arrangement of the two rectangular blocks and the two rectangular notches makes the connection operation between the upper circular torsion plate and the lower circular torsion plate simpler and faster.

[0014] Preferably, two symmetrically arranged lying L-shaped opening grooves are provided on the fixed sleeve, and the opening grooves extend in an arc along the circumferential surface of the fixed sleeve. Two outer protrusions are provided on the outer peripheral surface of the pipe sleeve, and the two outer protrusions can be respectively inserted downward and rotationally locked into the two opening grooves.

[0015] The arrangement of the two opening grooves and the two outer protrusions makes the connection operation between the fixed sleeve and the pipe sleeve simpler and the connection stability better.

[0016] Preferably, 4 upper ear plates are provided on the outer edge of the lower circular torsion plate, and 4 lower ear plates are provided on the outer peripheral surface of the circular enclosing plate. The 4 ear plate screw holes are respectively connected to 4 groups of corresponding upper ear plates and lower ear plates.

[0017] The arrangement of the 4 ear plate screw holes, the 4 upper ear plates and the 4 lower ear plates makes the connection between the lower circular torsion plate and the slide rail limit shell plate more stable and reliable.

[0018] Preferably, a strip-shaped protrusion is provided on the right edge of the front part of the quadrilateral blade, and a strip-shaped groove for accommodating the strip-shaped protrusion is provided on the left edge of the front part of the quadrilateral blade.

[0019] The arrangement of the strip-shaped protrusion and the strip-shaped groove enables the two sides of adjacent quadrilateral blades to be embedded and connected to each other, so that when the energy-saving air flow valve is closed, the air flow blocking performance is better.

[0023] Rotate the upper circular torsion plate, which drives the lower circular torsion plate and the slide rail limiting shell plate to rotate. The M long strip-shaped sliding holes drive the M quadrilateral blades to rotate respectively through the M cylindrical protrusions. At the same time, the opening sliding grooves of the quadrilateral blades drive the quadrilateral blades to slide along the corresponding lower protrusions, so that the quadrilateral blades realize rotation and radial movement;

[0026] Step 3: When it is necessary to use a certain radiation plate for refrigeration or heating, rotate the upper circular torsion plate corresponding to the radiation plate clockwise. The upper circular torsion plate drives the lower circular torsion plate and the slide rail limiting shell plate to rotate clockwise.

At the same time, the quadrilateral blades slide along the corresponding lower protrusions, and the quadrilateral blades rotate and move radially outward, and the opening degree of the energy-saving air flow valve gradually increases;

[0027] When the upper circular torsion plate cannot rotate clockwise any further, the M quadrilateral blades move into the cavity formed by the lower circular torsion plate and the slide rail limiting shell plate, the energy-saving air flow valve is fully opened, and the cold air or hot air in the floor cavity flows out, and the radiation plate performs temperature radiation;

[0028] Step 4: When it is not necessary to use the radiation plate for refrigeration or heating, rotate the upper circular torsion plate corresponding to the radiation plate counterclockwise.

[0048] As Figures 1-14 shown in the embodiment, it is a pluggable circumferential control type energy-saving air flow valve, including a closing assembly 1, a fixing sleeve 2, a pipe sleeve 3, and an upper circular torsion plate 4 that can be sleeved on the fixing sleeve; the closing assembly includes a lower circular torsion plate 11, an annular plate 12, 8 quadrilateral blades 13 with triangular fronts, and a circular rail limiting shell plate 14 arranged from top to bottom; the rail limiting shell plate includes a circular plate 140 and a circular surrounding plate 141 provided on the outer edge of the circular plate, and the outer edge of the lower circular torsion plate is fixedly connected to the circular surrounding plate; the lower part of the upper circular torsion plate is clamped with the inner edge of the lower circular torsion plate, and two horizontally extending fixing strips 21 are respectively provided on the lower left and lower right parts of the outer peripheral surface of the fixing sleeve, and the two fixing strips are located between the upper circular torsion plate and the lower circular torsion plate, and the upper surface of the annular plate is fixedly connected to the two fixing strips, and the pipe sleeve is clamped with the fixing sleeve; 8 uniformly distributed lower protrusions 121 are provided on the edge of the lower surface of the annular plate, a horizontally extending opening chute 131 is provided at the rear of the quadrilateral blade, and a cylindrical protrusion 132 is provided on the lower surface of the quadrilateral blade, and the cylindrical protrusion is close to the inner end of the opening chute; M lower protrusions respectively extend into the opening chutes of the 8 quadrilateral blades; 8 long strip-shaped sliding holes 142 are arranged in a circular arrangement along the inner edge of the rail limiting shell plate, and 8 cylindrical protrusions respectively extend into the 8 long strip-shaped sliding holes; the diameter of the inner edge of the lower circular torsion plate is larger than the diameter of the inner edge of the annular plate, the diameter of the inner edge of the annular plate is the same as the diameter of the inner edge of the rail limiting shell plate, and the angle of the front end of the quadrilateral blade is 45° ， The fronts of the respective quadrilateral blades can form a circular structure for closing the lower end of the fixing sleeve. Looking at the energy-saving air flow valve of the present invention from top to bottom, when the upper circular torsion plate is rotated clockwise, the respective quadrilateral blades gradually rotate and move radially outward and separate. The upper edge of the pipe sleeve is provided with an annular chamfer.

[0049] Two rectangular notches 41 are provided on the lower edge of the upper circular torsion plate, and two rectangular blocks 111 are provided on the inner edge of the lower circular torsion plate; the two rectangular blocks can be respectively connected in cooperation with the two rectangular notches.

[0050] The fixed sleeve is provided with two symmetrically arranged open slots 22 in a lying L shape on the left and right. The open slots extend in an arc along the circumferential surface of the fixed sleeve. Two outer protrusions 31 are provided on the outer peripheral surface of the pipe sleeve. The two outer protrusions can be respectively inserted downward and rotatably locked into the two open slots.

[0051] Four upper ear plates 112 are provided on the outer edge of the lower circular torsion plate. Four lower ear plates 143 are provided on the outer peripheral surface of the circular enclosure plate. The four ear plate screw holes are respectively connected to four groups of corresponding upper ear plates and lower ear plates.

[0052] A strip-shaped protrusion 133 is provided on the right edge of the front part of the quadrilateral blade. A strip-shaped groove 134 for accommodating the strip-shaped protrusion is provided on the left edge of the front part of the quadrilateral blade.

[0053] A usage method of a pluggable circumferential control type energy-saving air flow valve includes the following steps:

[0054] Step 1, 15 floor cavities are provided in the floor of the room equipped with the air-borne energy radiation air conditioner. The pluggable circumferential control type energy-saving air flow valve is installed on each floor cavity:

[0055] Open the cover plate of the floor cavity, fixedly connect two fixing strips to the lower surface of the cover plate, expose the upper part of the fixed sleeve and the two rectangular blocks outside the upper surface of the cover plate, make the sealing ring provided on the fixing hole of the cover plate be hermetically connected to the fixed sleeve and the two rectangular blocks, and cover the cover plate on the floor cavity;

[0056] Rotate the upper circular torsion plate. The upper circular torsion plate drives the lower circular torsion plate and the slide rail limiting shell plate to rotate. The eight long strip-shaped sliding holes drive the eight quadrilateral blades to rotate respectively through the eight cylindrical protrusions. At the same time, the opening sliding grooves of the quadrilateral blades drive the quadrilateral blades to slide along the corresponding lower protrusions, so that the quadrilateral blades realize rotation and radial movement;

[0057] Make the front parts of the eight quadrilateral blades form a circular structure. The circular structure closes the lower end of the fixed sleeve, and the energy-saving air flow valve is closed;

[0058] Step 2, according to the usage needs in the room, select 10 floor cavities, respectively insert the two outer protrusions of each pipe sleeve downward into the two open slots of the corresponding fixed sleeve, and rotate the pipe sleeve to make the two outer protrusions be locked to the bottom ends of the two open slots of the fixed sleeve;

[0059] Put the ten upper circular torsion plates on the ten fixed sleeves respectively, insert the two rectangular blocks of the floor cavity into the two rectangular notches of the corresponding upper circular torsion plates respectively, connect the ten pipe sleeves to the ten air-conditioning hoses respectively, and connect the ten air-conditioning hoses to the cavities of the ten radiation plates respectively;

[0060] Step 3: When it is necessary to use a certain radiation panel for refrigeration or heating, rotate the upper circular torsion plate corresponding to the radiation panel clockwise. The upper circular torsion plate drives the lower circular torsion plate and the slide rail limiting shell plate to rotate clockwise. The 8 long strip-shaped sliding holes drive the 8 quadrilateral blades to rotate clockwise through 8 cylindrical protrusions respectively. At the same time, the opening chute of the quadrilateral blade drives the quadrilateral blade to slide along the corresponding lower protrusion. The quadrilateral blade rotates and moves radially outwards, and the opening degree of the energy-saving air flow valve gradually increases.

[0061] When the upper circular torsion plate can no longer rotate clockwise, the 8 quadrilateral blades move into the cavity formed by the lower circular torsion plate and the slide rail limiting shell plate. The energy-saving air flow valve is fully opened, and the cold air or hot air in the floor cavity flows out, and the radiation panel performs temperature radiation.

[0062] Step 4: When it is not necessary to use the radiation panel for refrigeration or heating, rotate the upper circular torsion plate corresponding to the radiation panel counterclockwise. The quadrilateral blade rotates and moves radially inwards. When the upper circular torsion plate can no longer rotate counterclockwise, the front parts of the 8 quadrilateral blades form a circular structure. The circular structure closes the lower end of the fixed sleeve, the energy-saving air flow valve closes, and the radiation panel stops temperature radiation.

[0063] In addition, when the front parts of the 8 quadrilateral blades form a circular structure, the strip-shaped protrusion of one quadrilateral blade among two adjacent quadrilateral blades is inserted into the strip-shaped groove of the other quadrilateral blade, so that the circular structure plays a better role in blocking the air flow. As Figure 2 and Figure 12 shown, when the energy-saving air flow valve of the present invention is partially opened, each quadrilateral blade forms an octagonal opening.

[0064] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
