Abstract
The utility model discloses a constant-air-volume high-efficiency air supply unit. The constant-air-volume high-efficiency air supply unit comprises a static pressure box, an air diffusing plate and a high-efficiency filter; an air inlet of the constant-air-volume high-efficiency air supply unit is provided with an air volume adjustment device which comprises a rotation shaft, valve sheets and a spring; the rotation shaft is arranged on a radial plane of the air inlet; the valve sheets are arranged in a pair and rotate relative to each other around the rotation shaft in a hinge form; and the spring is connected with air inlet ends of the valve sheets; and in the constant-air-volume high-efficiency air supply unit, the air inlet area of the air inlet can be adjusted along with the magnitude of external air volume, and constant air inlet volume can be kept, so the constant air supply volume of the constant-air-volume high-efficiency air supply unit can be guaranteed.
Description
Technical field
The utility model relates to air cleaning facility, particularly relates to a kind of efficient blowing unit of air quantity of deciding.
Background technology
At present, along with being widely used of various electronic products, and raising medical, the food service industry production environment, the application of dust proof workshop is also more and more.In other toilet of various levels, the toilet below thousand grades has accounted for exhausted vast scale, and decides the efficient blowing unit of the air quantity equipment of the optimal pure air filtration in this type toilet just.The structure of deciding the efficient blowing unit of air quantity comprises plenum chamber, high efficiency particulate air filter and diffuser plate; Be installed in the top of toilet; Blower fan in the air-conditioning box is delivered to each with air through air-line system and decides the efficient blowing unit of air quantity; All in the market air outlets have only simple casing and high efficiency particulate air filter, perhaps increase a valve in the air inlet front side, regulate intake through closure manual or the motor regulated valve blade.In actual use, after high efficiency particulate air filter used the long period, resistance increased and reduces air quantity.Perhaps be not closed, cause the air output of the air outlet in all the other uses to increase because of the part air outlet need not use.The cleanliness factor requirement that these all can influence the toilet perhaps causes the air pressure of Cleanroom system uneven.When this situation occurring, the user has to put in order the air output of blower fan in the air-conditioning box, and perhaps by the valve of platform adjustment air outlet or air-line system, this workload is very huge.
The utility model content
It is simple in structure that the purpose of the utility model is to provide, can constant wind quantity decide the efficient blowing unit of air quantity.
For achieving the above object, the utility model provides a kind of efficient blowing unit of air quantity of deciding, and comprises plenum chamber, diffuser plate and high efficiency particulate air filter, and the said air inlet of deciding the efficient blowing unit of air quantity is provided with volume adjusting apparatus; Said volume adjusting apparatus comprises turning cylinder, valve block and spring; Said turning cylinder is located at the sagittal plane of said air inlet; Said valve block is provided with in pairs and relatively rotates around said turning cylinder with the hinge form; Said spring connects the inlet side of said valve block.
Preferably, said spring is a nonlinear spring.
Preferably, the said interface of deciding efficient blowing unit of air quantity and airduct is an apical grafting.
Preferably, the said interface of deciding efficient blowing unit of air quantity and airduct is a side joint.
Adopt the beneficial effect of present technique scheme to be: the air quantity size needs according to the user, can directly set the air quantity size, need not behind the scene, adjust again; When the environment for use of product changes, need not carry out manual adjustment yet, still can keep the air quantity requirement; Can save adjusting air-valve and a large amount of adjusting labour costs in the air-line system, can not influence the normal operation of toilet because of the delay of manual adjustment air quantity.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the front view of the utility model volume adjusting apparatus;
Fig. 3 is the vertical view of the utility model volume adjusting apparatus.
Wherein, 1. plenum chamber 11. air inlets 2. diffuser plates 3. high efficiency particulate air filters 4. volume adjusting apparatus 41. turning cylinders 42. valve blocks 43. nonlinear springs 5. airducts.
The specific embodiment
Specify the embodiment of the utility model below in conjunction with accompanying drawing.
Embodiment 1,
Referring to Fig. 1, shown in legend wherein, a kind ofly decide the efficient blowing unit of air quantity, comprise a plenum chamber 1, a diffuser plate 2 and a high efficiency particulate air filter 3, the said air inlet 11 of deciding the efficient blowing unit of air quantity is provided with a volume adjusting apparatus 4; Said volume adjusting apparatus 4 comprises a turning cylinder 41, a pair of valve block 42 and a nonlinear spring 43; Said turning cylinder 41 is located at the sagittal plane of said air inlet 11; Said valve block 42 relatively rotates around said turning cylinder 41 with the hinge form; Said nonlinear spring 43 connects the inlet side of said valve block.
The said interface of deciding efficient blowing unit of air quantity and airduct 5 is an apical grafting.
Introduce the operation principle of the utility model below.
At first require to set the tension force of nonlinear spring 43, can export certain air quantity to guarantee product, in the normal use of product according to air quantity; Valve block 42 will be kept at an angle operation, and when the rising of high efficiency particulate air filter 3 resistances, perhaps airduct 5 stops up; When causing intake to tail off, nonlinear spring 43 is stressed to diminish and shrinks, and valve block 42 closes up; The pipe ventilated area of air inlet 11 is increased, and air output increases.When the intake of pipe-line system increased, valve block 42 suffered pressure increased, and nonlinear spring 43 stressed increases and distortion increase, and valve block 42 opens, and the air intake passage draught area of air inlet is diminished, and reduces intake, thereby reaches the effect of constant air output.
Embodiment 2,
All the other are identical with embodiment 1, and difference is that the said interface of deciding efficient blowing unit of air quantity and airduct is a side joint.
Adopt the beneficial effect of present technique scheme to be: the air quantity size needs according to the user, can directly set the air quantity size, need not behind the scene, adjust again; When the environment for use of product changes, need not carry out manual adjustment yet, still can keep the air quantity requirement; Can save adjusting air-valve and a large amount of adjusting labour costs in the air-line system, can not influence the normal operation of toilet because of the delay of manual adjustment air quantity.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, these all belong to the protection domain of the utility model.
