Detailed description of the invention
The utility model will be further described with embodiment below in conjunction with the accompanying drawings.
A kind of semi-active control valve for gas passage, as depicted in figs. 1 and 2, it include the valve body 7 of both ends open with
And it being positioned at the valve block 10 of valve body 7, one end of described valve body 7 is air inlet port 71 and the other end is air outlet 72, and it is also
Including the rocker-arm link assembly controlling valve block 10 aperture.
As shown in Figure 4, described valve block 10 is made up of with the shaft 103 with axis hole 105 diaphragm seal portion 104, valve block 10
Diaphragm seal portion 104 keep off in the gas channel between air inlet port 71 and air outlet 72, the axis hole 105 of valve block 10 and valve
The central axis of body 7.
Described rocker-arm link assembly includes rocking arm 16, connecting rod 17, valve block connecting shaft 9 and spring 14, as it is shown on figure 3, described
The one end of rocking arm 16 is rotationally connected with valve body 7 and rotational plane is parallel with the central shaft of valve body 7, the other end of rocking arm 16
Offer the bar shaped pilot hole 161 of central shaft and the central axis of valve body 7；One end of described connecting rod 17 is fixed with rocking arm and connects
Axle 15, this rocking arm connecting shaft 15 is limited in bar shaped pilot hole 161, the other end of connecting rod 17 and one end of valve block connecting shaft 9
Fixing connection, valve block connecting shaft 9 and axis hole 105 secure fit of valve block 10.
One end of described spring 14 is fixing with rocking arm 16 to be connected, and the other end of spring 14 is fixed on valve body 7 and makes spring 14
The change of decrement is ordered about rocking arm 16 and is rotated；And when spring 14 is in minimal compression amount, its elastic force passes through rocking arm 16, rocking arm
Connecting shaft 15, connecting rod 17, valve block connecting shaft 9 act on valve block 10, make the diaphragm seal portion 104 of valve block 10 to air inlet port
71 apply a power contrary with airflow direction, and spring 14 is in compressive state all the time, to ensure externally to provide elastic force.
The axis hole 105 of above-mentioned valve block 10 uses after coordinating with valve block connecting shaft 9 and is welded and fixed and is integrated, and valve block connecting shaft 9 can be
For its hole passed rotates on valve body 7.Connecting rod 17 is used to crimp between valve block connecting shaft 9 with rocking arm connecting shaft 15, rocking arm
Connecting shaft 15 can be slided in the bar shaped pilot hole 161 of rocking arm 16.
When air-flow enters the speed of air inlet port 71 more than setting value, now air-flow just overcomes bullet to the active force of valve block 10
The pressure that spring 14 applies when being in sealing state in diaphragm seal portion 104, valve just can be opened.Along with the increase of air velocity,
The diaphragm seal portion 104 of valve block 10 is also gradually increased until reaching maximum opening.When the speed of air-flow is less than setting value, this seasonal epidemic pathogens
Flow the pressure that the active force to valve block 10 is not enough to overcome spring 14 to apply when being in sealing state in diaphragm seal portion 104, valve
Can not open.
The opening angle of valve block 10 and stream pressure (also representing air velocity) are in corresponding relation, and the opening angle of valve block 10 is more
Greatly, the decrement being made spring 14 by rocker-arm link assembly is the biggest, and the reactive spring force being subject to is the biggest, when spring 14
During the pressure equalizing gas flow being subject to the active force of valve block 10 with valve block 10, valve block 10 aperture is certain.By coupling spring 14
The unlatching rotating speed of stiffness reliability valve block 10 and opening angle, it is ensured that valve block 10 smooth motion, the air-flow entering gas passage is put down
Steady increase and decrease.
As shown in Figure 4, the two sides in the diaphragm seal portion 104 of described valve block 10 is respectively provided with a cannelure 101, described cannelure 101
In be provided with packer ring 11.By diaphragm seal portion 104 towards as a example by the one side of air inlet port 71, its cannelure 101 and air inlet
Port 71 coordinates and realizes sealing by packer ring 11, and caulking gum 11 must reserve certain decrement, it is ensured that half actively
Control the sealing property of valve 5.The cannelure 101 of described valve block 10 is along the circumferential direction uniformly provided with the circular hole 102 of complete cycle,
Described packer ring 11 has and the fitting portion of circular hole 102 secure fit, for fixing seal rubber 11.
Described rocking arm 16, spring 14 and connecting rod 17 are positioned at outside valve body 7, and rocking arm 16 is by pad 12 and bolt 13 and valve body 7
Outer wall be rotationally connected, it is achieved axial limiting.
