Description

Technical Field

[0001] The utility model relates to the technical field of regulating valves, in particular to an air volume regulating valve. Background Art

[0002] The air volume regulating valve is a device used to adjust the air flow rate and is widely used in various ventilation and air conditioning systems. The main function of this valve is to adjust the resistance to air flow to achieve precise control of the air volume. The working principle of the air volume regulating valve is to adjust the resistance to air flow by changing the opening of the valve. When the valve opening increases, the resistance to air flow decreases and the air volume increases; conversely, when the valve opening decreases, the resistance to air flow increases and the air volume decreases. By continuously adjusting the opening of the valve, precise control of the air volume can be achieved to meet the needs of different occasions; the air volume regulating valve has the advantages of simple structure, flexible adjustment, and good sealing, so it has been widely used in ventilation and air conditioning systems. In practical applications, it is necessary to select appropriate air volume regulating valve models and specifications according to the specific use environment and needs to ensure the normal operation of the system and the stability of air quality. The regulating blades of the air volume regulating valve are mostly double-opening, so when the blades are rotated, both sides of the blades can be ventilated, which will cause the baffle effect to be much worse, and then the change in the control air volume is not obvious enough, and the sealing performance when connected to the pipeline needs to be improved. For example, "Utility Model CN219994406U A kind of air volume regulating valve The utility model can conveniently control the use of the adjustment plate through the adjustment component, so as to facilitate the opening and closing size of the opening in the installation frame, so as to ensure that the air volume regulation effect is obvious; the utility model can ensure good sealing when the installation frame is connected to the pipeline through the sealing component, and can prevent air leakage." In view of the above problems, there may be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above purpose, the utility model is implemented through the following technical solutions: an air volume regulating valve, comprising: a regulating valve housing, an air inlet diameter reducing ring and an air outlet diameter reducing ring, the air inlet diameter reducing ring is installed on the regulating valve housing, the air outlet diameter reducing ring is installed on the regulating valve housing, an inner shell self-tightening wind blocking structure is installed in the regulating valve housing, and auxiliary sealing components are installed on the air inlet diameter reducing ring and the air outlet diameter reducing ring respectively;

[0004] The self-tightening wind-blocking structure in the shell includes: a variable diameter zoom bearing frame, an annular composite wind-blocking sail cloth surface, a rope-coated nylon sleeve, an adjustment rope, a rope adjustment buckle, a rope-bearing hub, and an integrated winding motor;

[0005] The variable diameter zoom carrier is installed in the regulating valve housing, the annular composite wind-blocking sail cloth surface is installed in the regulating valve housing, the rope-coated nylon sleeve is installed on the annular composite wind-blocking sail cloth surface, and one side of the rope-coated nylon sleeve is fixedly connected to the variable diameter zoom carrier, the rope adjustment buckle is installed in the rope-coated nylon sleeve, the adjustment rope is inserted on the rope adjustment buckle, and the adjustment rope is inserted in the rope-coated nylon sleeve, the integrated winding motor is installed in the variable diameter zoom carrier, the rope bearing hub is connected to the integrated winding motor, and the adjustment rope is sleeved on the rope bearing hub.

[0006] It should be noted that in the above, the air inlet duct is screwed and connected through the coupling thread provided in the air inlet reducer, and the air outlet duct is connected to the air outlet reducer by the same operation. At this time, the gas or air will flow into the regulating valve housing from the air inlet reducer, and then flow out from the air outlet reducer. When the ventilation volume inside needs to be adjusted, the integrated winding motor in the variable diameter scaling carrier is driven, and the operation of the integrated winding motor drives the rope bearing hub to rotate, thereby causing the total exposed length of the adjustment rope wrapped thereon to change, and the adjustment rope passes through the rope adjustment buckle through the U-shaped connecting slide groove provided in the rope adjustment buckle, and the terminal end of the adjustment rope is connected to the rope adjustment buckle. Therefore, when the total leakage length of the adjustment rope is shortened, the adjustment rope slides in the U-shaped connecting slide groove, so that the rope loop formed by the exposed section of the adjustment rope as a whole shrinks, thereby causing the rope-coated nylon sleeve mounted on the outside of the exposed section to shrink and tighten, and because a part of the rope-coated nylon sleeve is fixedly connected to the variable diameter scaling carrier. Therefore, when the rope-covered nylon sleeve is tightened to the end, it will completely wrap the variable-diameter zoom carrier and get stuck in the recessed position set on the variable-diameter zoom carrier, so that the open side of the annular composite wind-blocking sail cloth surface is completely retracted and forms a complete closed surface with the variable-diameter zoom carrier, thereby cutting off the air flow. When the air volume needs to be adjusted, just drive the integrated winding motor and the rope bearing hub connected thereto to release a section of the adjustment rope again. Under the flow of gas, the annular composite wind-blocking sail cloth surface is stretched open, and the annular composite wind-blocking sail cloth surface and the variable-diameter zoom carrier will form a gap again, thereby releasing gas and forming flow. In summary, it can be concluded that the air volume can be accurately adjusted by controlling the length of the exposed section of the adjustment rope, thereby controlling the size of the gap between the annular composite wind-blocking sail cloth surface and the variable-diameter zoom carrier, and the polyester fiber covering layer provided on the annular composite wind-blocking sail cloth surface can make the annular composite wind-blocking sail cloth surface more resilient and windproof, thereby improving the durability of the overall regulating valve.

[0007] Preferably, the auxiliary sealing assembly comprises: a pair of inflatable air cores and a pair of auxiliary sealing air rings;

[0008] A pair of the inflatable air cores are respectively inserted into the air inlet reducing ring and the air outlet reducing ring, and the pair of the inflatable air cores are respectively connected to a pair of the auxiliary sealing air rings, and the pair of the auxiliary sealing air rings are respectively installed in the air inlet reducing ring and the air outlet reducing ring;

[0009] It should be noted that, in the above, after the air outlet duct and the air inlet duct are screwed and connected with the air inlet reducing ring and the air outlet reducing ring respectively, a pair of inflatable air cores are inflated respectively, and the gas will flow from the inflatable air core into the corresponding auxiliary sealing air ring, thereby filling the gap between the duct and the reducing ring to prevent gas leakage or air leakage.

[0010] Preferably, a coupling thread is provided in the air inlet diameter reducing ring;

[0011] Preferably, a coupling thread is provided in the air outlet diameter reducing ring;

[0012] Preferably, a polyester fiber covering layer is provided on the surface of the annular composite wind-blocking sail cloth;

[0013] Preferably, a U-shaped connecting groove is provided in the rope adjustment buckle.

[0014] Beneficial Effects

[0015] The utility model provides an air volume regulating valve. It has the following beneficial effects. Compared with the prior art, the air volume regulating valve has the following advantages: the regulating valve uses a self-tightening wind-blocking structure in the shell to pass through a flexible annular composite wind-blocking canvas, and cooperates with a cylindrical semi-suspended variable diameter scaling bearing frame to adjust the gap size between the two, so as to control the air flux in the regulating valve, thereby realizing air volume regulation. This design can reduce the weight of the regulating valve to the greatest extent, and has an excellent air volume regulation effect. It is superior to general air volume regulating valves in terms of cost saving and easy installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1-4As shown, an air volume regulating valve comprises: a regulating valve housing 1, an air inlet reducing ring 2 and an air outlet reducing ring 3, wherein the air inlet reducing ring 2 is mounted on the regulating valve housing 1, and the air outlet reducing ring 3 is mounted on the regulating valve housing 1, an in-shell self-tightening wind-blocking structure is mounted in the regulating valve housing 1, and auxiliary closing components are mounted on the air inlet reducing ring 2 and the air outlet reducing ring 3 respectively; the in-shell self-tightening wind-blocking structure comprises: a variable diameter and scaling bearing frame 4, an annular composite wind-blocking sail cloth surface 5, a rope coated nylon sleeve 6, an adjustment rope 7, a rope adjustment buckle 8, a rope bearing hub 9 and an integrated winding motor 10; the variable diameter and scaling bearing frame 4 is mounted in the regulating valve housing 1, the annular composite wind-blocking sail cloth surface 5 is mounted in the regulating valve housing 1, the rope coated nylon sleeve 6 is mounted on the annular composite wind-blocking sail cloth surface 5, and the rope coated nylon One side of the sleeve 6 is fixedly connected to the variable diameter and zoom bearing frame 4, the rope adjustment buckle 8 is installed in the rope coated nylon sleeve 6, the adjustment rope 7 is inserted on the rope adjustment buckle 8, and the adjustment rope 7 is inserted in the rope coated nylon sleeve 6, the integrated winding motor 10 is installed in the variable diameter and zoom bearing frame 4, the rope bearing hub 9 is connected to the integrated winding motor 10, and the adjustment rope 7 is sleeved on the rope bearing hub 9; the auxiliary closing component includes: a pair of inflatable air cores 11 and a pair of auxiliary sealing air rings 12; the pair of inflatable air cores 11 are respectively inserted into the air inlet variable diameter ring 2 and the air outlet variable diameter ring 3, and the pair of inflatable air cores 11 are respectively connected to a pair of auxiliary sealing air rings 12, and a pair of auxiliary sealing air rings 12 are respectively installed in the air inlet variable diameter ring 2 and the air outlet variable diameter ring 3.

[0025] According to the attached Figure 1-4It is concluded that the air inlet duct is screwed and connected through the coupling thread set in the air inlet reducer 2, and the air outlet duct is connected to the air outlet reducer 3 by the same operation. At this time, the gas or air will flow into the regulating valve housing 1 from the air inlet reducer 2, and then flow out from the air outlet reducer 3. When the ventilation volume inside needs to be adjusted, the integrated winding motor 10 in the variable diameter zoom carrier 4 is driven. The operation of the integrated winding motor 10 drives the rope bearing hub 9 to rotate, thereby changing the total exposed length of the adjustment rope 7 wound thereon. The adjustment rope 7 is connected through the U-shaped connection set in the rope adjustment buckle 8. The U-shaped connecting groove passes through the rope adjustment buckle 8, and the terminal end of the adjustment rope 7 is connected to the rope adjustment buckle. Therefore, when the total length of the adjustment rope 7 is shortened, the adjustment rope 7 slides in the U-shaped connecting groove, so that the rope loop formed by the exposed section of the adjustment rope 7 as a whole shrinks, thereby shrinking the rope-covered nylon sleeve 6 sleeved on the outside of the exposed section, and because a part of the rope-covered nylon sleeve 6 is fixedly connected to the variable-diameter zoom carrier 4, the rope-covered nylon sleeve 6 will completely wrap the variable-diameter zoom carrier 4 when it is tightened, and get stuck in the recessed position set on the variable-diameter zoom carrier 4, so that The open side of the annular composite wind-blocking sail cloth 5 is completely retracted, and forms a complete closed surface with the variable-diameter zoom carrier 4, thereby cutting off the air flow. When the air volume needs to be adjusted, just drive the integrated winding motor 10 and the rope bearing hub 9 connected thereto to release a section of the adjustment rope 7 again. Under the flow of gas, the annular composite wind-blocking sail cloth 5 is stretched open, and the annular composite wind-blocking sail cloth 5 and the variable-diameter zoom carrier 4 will form a gap again, thereby releasing gas and forming flow. In summary, it can be concluded that the length of the exposed section of the adjustment rope 7 can be controlled to control the annular composite wind-blocking sail cloth 5. The size of the gap between the sail cloth surface 5 and the variable diameter scaling carrier frame 4 can accurately adjust the air volume. The polyester fiber covering layer arranged on the annular composite wind-blocking sail cloth surface 5 can make the annular composite wind-blocking sail cloth surface 5 more resilient and windproof, thereby improving the durability of the overall regulating valve; when the air outlet duct and the air inlet duct are respectively screwed and connected with the air inlet reducing ring 2 and the air outlet reducing ring 3, a pair of inflatable air cores 11 are inflated respectively, and the gas will flow from the inflatable air core 11 into the corresponding auxiliary sealing air ring 12, thereby filling the gap between the duct and the reducing ring to prevent gas leakage or air leakage.
