Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning duct components, and more particularly to an environmentally friendly air conditioning air flow control valve component. Background Art

[0002] Air conditioning wind control components usually consist of air conditioning ducts and air volume control valves. Among them, air conditioning ducts are pipe components used for air delivery and distribution, and there are two types: composite ducts and inorganic ducts. The production of stainless steel ducts is to apply sealant to the gaps such as the bite seams, rivet seams, and the four corners of the flange. The surface dust and oil should be removed before applying the sealant; according to the cross-sectional shape, the duct can be divided into circular ducts, rectangular ducts, oblate ducts, etc. Among them, the circular duct has the smallest resistance but the largest height size, and the production is complex, so the application is mainly rectangular ducts. The air volume control valve is an indispensable central air conditioning terminal accessory in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings. It is generally used in air conditioning and ventilation component pipes to adjust the air volume of the branch pipe, and can also be used for the mixed adjustment of fresh air and return air.

[0003] However, the existing air conditioning air control valve components have the following disadvantages:

[0004] 1) The air valve has a single structure, and the air volume and blowing direction are often adjusted by flipping the blades, which causes uneven blowing and affects the air conditioning effect;

[0005] 2) When the air-conditioning wind speed is high, a lot of noise will be generated in the air duct;

[0006] 3) The end connections of the air duct are not stable, which may cause leaks or deviations, affecting the normal delivery of cold and hot air and reducing the working efficiency of the air conditioner.

[0007] Therefore, it is an urgent problem to be solved by technical personnel in this field to provide an environmentally friendly air conditioning air control valve component with good blowing effect and high blowing efficiency. Summary of the invention

[0008] In view of this, the present invention provides an environmentally friendly air conditioning air flow control valve component, which blows air evenly when the air volume is adjusted, thereby improving the use effect of the air conditioner and avoiding air leakage in the air duct during the transportation process, thereby improving the working efficiency of the air conditioner and reducing noise to meet user needs.

[0009] In order to achieve the above object, the present invention adopts the following technical solution:

[0010] An environmentally friendly air conditioning air flow control valve component, comprising a frame, a ventilation plate and an air control component;

[0011] The frame is cylindrical;

[0012] The ventilation plate has a plurality of ventilation holes arranged in a ring shape; the ventilation plate is installed at the bottom of the frame;

[0013] The wind control assembly includes a support rod, a sliding sleeve, two hydraulic cylinders, a plurality of stretching connecting rods and a plurality of blades; the support rod is vertically fixed at a central position between the crossbeam at the top of the frame and the ventilation plate; the sliding sleeve is sleeved on the support rod; the two hydraulic cylinders are symmetrically arranged on both sides of the support rod, and the cylinder bodies of the two hydraulic cylinders are fixed on the crossbeam, and the telescopic rods of the two hydraulic cylinders are respectively connected to the two sides of the top of the sliding sleeve; one end of the plurality of stretching connecting rods are hinged on the sliding sleeve and are evenly distributed along its circumference, and the other ends of the plurality of stretching connecting rods are respectively hinged to the middle parts of the plurality of blades; the plurality of blades are L-shaped, and their corner ends are arc surfaces.

[0014] By adopting the above scheme, the beneficial effects of the present invention are:

[0015] Under the action of two hydraulic cylinders, the sleeve moves up and down on the support rod. One end of the stretching connecting rod is hinged on the circumference of the sleeve, and the other end is hinged with a blade. When the sleeve rises, the stretching connecting rod is retracted inward under the action of the gravity of the blade, and the blade naturally droops. At this time, the ventilation plate is in a ventilation state. When the sleeve descends, until the arc surface of the L-shaped blade contacts the ventilation plate, the stretching connecting rod expands outward. When the blade is completely spread on the ventilation plate, the ventilation hole is completely blocked, and it is in a closed state. In this process, cold and hot air are always diffused through the ventilation holes, so that uniform blowing can be achieved while the air volume is adjusted, and the air conditioning effect is improved.

[0016] Furthermore, it also includes impedance muffler, formaldehyde-free environmentally friendly muffler air duct and muffler elbow;

[0017] The impedance muffler, the formaldehyde-free environmentally friendly muffler air duct and the muffler elbow are sequentially connected as a whole;

[0018] The frame is mounted on the extended end of the muffler elbow.

[0019] The beneficial technical effect produced by adopting the above-mentioned further technical solution is to reduce noise and meet user needs.

[0020] Further, the impedance muffler includes a muffler pipe, a resistive expansion chamber and a resistive sound absorbing sheet;

[0021] The muffler pipe is provided with a plurality of partitions distributed at intervals along its length direction;

[0022] The resistant expansion chamber is coated on the periphery of the muffler pipe, and the resistant expansion chamber is communicated with the muffler pipe;

[0023] The resistive sound absorbing sheet is arranged between the resistant expansion chamber and the silencing duct.

[0024] The beneficial technical effect produced by adopting the above-mentioned further technical solution is that the sound absorption and sound reflection effects are combined to eliminate noise, and it can achieve excellent sound-absorbing effect when installed in the air duct.

[0025] Furthermore, the formaldehyde-free, environmentally friendly, sound-absorbing air duct comprises an antibacterial material coating, high-density formaldehyde-free glass wool, a reinforced aluminum foil and a metallized polypropylene film. The antibacterial material coating, the high-density formaldehyde-free glass wool, the reinforced aluminum foil and the metallized polypropylene film are sequentially bonded together from the inside to the outside or connected together by insulation nails.

[0026] The beneficial technical effect produced by adopting the above-mentioned further technical scheme is that the antibacterial material coating can inhibit the growth of bacteria and microorganisms, the aluminum foil of the reinforced belt is covered on the surface of the high-density formaldehyde-free glass wool, which is durable and fireproof, and the metallized polypropylene film is coated on the aluminum foil of the reinforced belt, which is not glaring and has excellent corrosion resistance, truly achieving an environmental protection effect.

[0027] Furthermore, the thickness of the aluminum foil of the ribbed strip is 0.3-0.5 mm.

[0028] Furthermore, two symmetrically distributed first bumps and two symmetrically distributed second bumps are sequentially arranged on the inner wall of the formaldehyde-free environmentally friendly sound-absorbing air duct along its length direction, and the height of the first bump is greater than the height of the second bump.

[0029] The beneficial technical effect produced by adopting the above-mentioned further technical scheme is that a first bump and a second bump are arranged in the formaldehyde-free environmentally friendly sound-absorbing air duct to block part of the noise, and the channel formed between the first bumps is smaller than the channel formed between the second bumps, which can reduce the effective expansion ratio and reduce the sound insulation value.

[0030] Furthermore, the length of the silencer pipe is greater than the length of the resistant expansion chamber; the extended end of the silencer pipe is sleeved in the formaldehyde-free environmentally friendly silencer air duct, and the silencer pipe is fastened to the formaldehyde-free environmentally friendly silencer air duct by screws or tension bolts.

[0031] The beneficial technical effect produced by adopting the above-mentioned further technical scheme is that the silencer pipe is sleeved and connected with the formaldehyde-free environmentally friendly silencer air duct, and is fastened by screws or tension bolts, which can avoid air leakage in the air duct during transportation and improve the working efficiency of the air conditioner.

[0032] Furthermore, one end of the silencer elbow connected to the formaldehyde-free environmentally friendly silencer air duct is square, and one end of the silencer elbow connected to the frame is round.

[0033] Furthermore, the blade includes a fan-shaped baffle and an arc guide plate, the fan-shaped baffle and the arc guide plate are connected as a whole, and the arc surface is formed at the connection between the fan-shaped baffle and the arc guide plate.

[0034] The beneficial technical effect produced by adopting the above-mentioned further technical scheme is that the design of the fan-shaped baffle matches the circular ventilation plate, which can completely cover the ventilation hole. The arc guide plate can guide the conversion of the fan-shaped baffle between the vertical state and the horizontal state during the lifting and lowering of the sliding sleeve, avoiding the ventilation or shielding effect due to sticking.

[0035] Furthermore, the ventilation hole is circular. BRIEF DESCRIPTION OF THE DRAWINGS
