Brief description of the drawings
Fig. 1 is the side, sectional structural representation for determining air quantity valve in the utility model embodiment；
Fig. 2 is the partial schematic diagram for determining air quantity valve in the utility model embodiment.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type is described in further detail.
As depicted in figs. 1 and 2, present embodiments provide it is a kind of determine air quantity valve, including valve body 1, the master that is arranged on valve body 1
Axle 2, connecting rod 3, spring leaf 4, cam 5, valve block 6, air bag 7 and stop block 8, the main shaft 2 are arranged in valve body 1, the main shaft 2
The valve block 6 is fixed on along the diametric(al) of the valve block 6, makes valve block 6 in valve body 1 as main shaft 2 rotates.The connecting rod
3 one end are connected by bolt 31 with the main shaft 2, and the other end is connected by bolt 31 with the spring leaf 4, in its of the application
In his embodiment, the connecting rod can also be attached by modes such as welding with the main shaft, and the connecting rod can also pass through
The modes such as welding are attached with the spring leaf.The cam 5 is fixed on valve body 1, is connected with the spring leaf 4.Air bag 7
It is arranged on main shaft 2, the air bag 7 communicates provided with aperture 71 with the valve block 6, it is preferred that the material of the air bag is silica gel,
In the other embodiment of the application, the material of the air bag can also be resin, but not limited to this.Also set in the valve body 1
There is stop block 8, the stop block is used for the maximum opening for limiting valve block.Specifically, the outside of valve body 1 is provided with air quantity graduation apparatus
11 and pointer 12, the pointer 12 be connected with the spring leaf 4.
The operation principle of the present embodiment：When the wind velocity increases（That is pressure increase）, made by the aperture communicated with valve block
Air bag is expanded, and on the one hand enhances the closing torque of valve block, and the closing forces of valve block are amplified, in favor of control, another aspect
It slow down the vibration of valve block.It is corresponding with the closing torque of valve block, an opposite force is applied to valve block by spring leaf, with recuperation valve
Closing torque on piece.In this way, in pipeline pressure increase, air bag expansion, closing torque strengthens, and valve block is transported to closing direction
It is dynamic, and balanced by spring leaf, the local resistance for determining air quantity valve is added, the effect of decompression is served, maintains air quantity
It is constant.Conversely, when wind speed is reduced（I.e. pressure reduces）, air bag shrink, closing torque weaken, valve block to opening direction transport
It is dynamic, air quantity is remained unchanged.Thus, the device is pure mechanic structure, it is not necessary to outside resources, so that it may plays the work for determining air quantity
With.In order to keep the adjustability of air quantity, spring leaf is connected on cam, cam curve is according to tight calculating and substantial amounts of examination
Test and make, the pulling force of spring leaf is different with the position of cam and changes, and different pulling force corresponds to different air quantity, outside valve body
Air quantity graduation apparatus is provided with, the spring leaf is connected to pointer, so as to measure the size of air output.Air quantity valve is determined not only with fixed
The effect of air quantity, while can also correspond to the effect that graduation apparatus carries out air quantity regulation.
Compared with prior art, the beneficial effects of the utility model are：
1st, it is provided by the utility model a kind of to determine air quantity valve, including valve body, the main shaft being arranged on valve body, connecting rod, spring
Piece, cam, valve block, air bag and stop block, described connecting rod one end are connected with the main shaft, and the other end is connected with the spring leaf,
The other end of the spring leaf is connected with cam, and the cam is fixed on valve body, and the valve block and air bag are arranged on main shaft,
The air bag is come round provided with aperture with valve block, and the stop tab is arranged in valve body, for limiting the maximum opening of valve block.It is above-mentioned
Determine air quantity valve simple in construction, automation structure, need not prevent circuit abnormality or aging from causing to determine wind by electric signal transmission
Amount valve is failure to actuate, and by the angle of air bag regulating valve piece, so as to adjust air quantity, air quantity is in constant state, in addition, in valve
