Abstract
The utility model discloses a high-sealing-performance air valve which comprises a frame body. Blades are arranged in the frame body, a butt joint hasp is arranged at the free end of each blade, and the butt joint hasps are in V shapes. Alternatively, the butt joint hasps are in arc shapes. According to the high-sealing-performance air valve, the production processes and the production cost are not increased, the blades resist to bending and deformation in the machining process, the coincident sealing degree between arc sealing sheets and the two ends of the blades is high, and the closed effect is improved.
Description
Technical field
The utility model relates to a kind of high leakproofness air-valve.
Background technology
Air-valve, as its name suggests, i.e. volume damper.Volume damper is indispensable tail end of central air conditioner accessory in ventilation, air conditioning and the air purification engineering of industrial premises civil buildings, generally be used in air-conditioning, in air system plumbing, be used for regulating the air quantity of arm, also can be used for the adjusting that mixes of new wind and return air.
Yet existing air-valve has following defect:
1, the blade of air-valve is with plane overlapping mode, in the situation that closing, because easy torsional deformation in process affects coincidence sealing property, in overlap joint process, because being the overlapping easy generation of plane gap, does not reach good obturation effect;
2, the seal groove at blade and two ends pastes when overlapping, and blade rotor and groove have a copper sheathing pad between pasting, and because pad self has the thickness of 1.2 millimeters～2 millimeters, has just naturally produced the gap of 1.2 millimeters～2 millimeters, so sealing effectiveness is poor.
Utility model content
Primary and foremost purpose of the present utility model is to provide a kind of high leakproofness air-valve of good sealing effect.Scheme of the present utility model is as follows for achieving the above object:
A high leakproofness air-valve, comprises framework, in described framework, is provided with blade, and described blade free end is provided with docking hasp, and described docking hasp is V-shaped.
Optionally, described docking hasp is curved.
The high leakproofness air-valve that the utility model provides does not increase production process and production cost, and blade is counter-bending and distortion in process, and the arc diaphragm seal tightness that overlaps with blade two ends is higher, raising obturation effect.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model embodiment 1 blade opening structural representation;
Fig. 2 is the utility model embodiment 1 blade closure state structural representation;
Fig. 3 is the utility model embodiment 2 blade opening structural representations;
Fig. 4 is the utility model embodiment 2 blade closure state structural representations.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the utility model in detail, in this illustrative examples of the present utility model and explanation, be used for explaining the utility model, but not as to restriction of the present utility model.
As Fig. 1, shown in Fig. 2, a kind of high leakproofness air-valve, comprise framework 1, make framework 1 and require the thickness of the plate material that adopts and the bearing requirements that manufacture craft meets different system air-valve, framework 1 is for providing air channel, on the duct cross-section of described framework 1, be provided with bearing, blade 2 fixedly secures on bearing, bearing rotates flexibly, while bearing size and intensity meet bears blast, high temperature resistant and fire protection requirement, bearing is non-maintaining design, blade 2 quantity are plural pieces, adopt galvanizing low carbon steel plate to make and meet pressure-bearing, the requirements such as heatproof fire prevention, blade 2 is connected with executing agency by transmission mechanism, whole transmission mechanism can make the synchronous tight closing of whole blades 2 and the unlatching of whole air-valve, guarantee the control accuracy of whole air-valve and the requirement of low leakage, executing agency is controlled by control panel, and have: remote electronic control and on-site manual are controlled function, mechanical and electric two kinds of stopping means, delayed alarm function, and electric/manual change-over switch is set, YE is connected by employing square shaft with the connected mode of air-valve rotating shaft, effectively prevent from skidding, described blade 2 free ends are provided with docking hasp 21, described docking hasp 21 is V-shaped.
The sealing strip that the high leakproofness air-valve that above-described embodiment scheme provides removes original quadrate lope sheet 2 two ends changes to present docking hasp 21, has improved the sealing resistance to compression effect of former blade 2 overlap joints and the effect of leaking out.
As shown in Figure 3, Figure 4, embodiment 2 overall technical architectures are identical with embodiment 1, institute's difference is, described docking hasp 21 is curved, by above-described embodiment scheme, is improving on the sealing resistance to compression effect of former blade 2 overlap joints and the basis of the effect of leaking out, during coincidence, utilize the principle of rising-heat contracting-cold and the principle of extruding, make the docking hasp 21 of blade 2 closely sealed, when closing, reach the effect of gapless coincidence, reduce inleakage.
Embodiment recited above is described preferred embodiment of the present utility model, not design of the present utility model and scope is limited.Do not departing under the prerequisite of the utility model design concept; various modification and improvement that this area ordinary person makes the technical solution of the utility model; all should drop into protection domain of the present utility model; the technology contents that the utility model is asked for protection, is all documented in claims.
