无压风门
In the coal mine ventilation system, damper is a kind of
common ventilation facilities, plays a very important role
in safety production of coal mine.

煤矿矿井通风系统中,风(feng)门(men)是一种常用
的通风设施,在煤(mei)矿安全生产中起着非常
重要的 作用

无压风门适用于
煤矿井下巷道任何需要安设风门的地点

无压风门主要用于矿山井下进回巷和主要进回风巷之间每个联络巷中
是目前所有风门的替代品

Non pressure air door is mainly used for underground mine into the back alley
And main return airway in between each contact Lane
Are all door alternatives.

无压风门

无压风门是目前我国煤矿井下较为理想的一种风门,主要用于矿山井下进回风
巷和主要进回风巷之间每个联络巷中,它打破了长期以来老式传统风门的结构型式,
巧妙地把作用在风门上的风压通过平衡结构将其转化为一种内力,充分显示出该风
门结构特点。

Non pressure air door is a door of the ideal of underground coal mine in China, mainly used for underground
mine in return airway and main return airway between each connection, it has broken the traditional door
structure for a long time, cleverly to wind pressure on the air door through the balance structure is transformed
into a internal force, fully demonstrated the unique air structure
无压风门

无压风门使用简单,安全可靠等优点,受到专家和用户的高
度评价,是目前这些风巷中所用风门的替代品。

Non pressure air door is simple to use, safe and reliable, highly evaluated by
experts and users, is currently used in the airway of an alternative.

无压风门(men)是(shi)由门(men)框、门(men)扇、连(lian)杆平衡机构和重锤等部分组成(cheng)

Non pressure air door is composed of a door frame,
door leaf, connecting rod balancing mechanism and a weight etc

两扇风门分别向两个方向开启,通过连杆和支撑臂实现联动
改变连杆长度可以调整风门的严密度

The two air doors were opened in two directions
To realize linkage through the connecting rod and the support arm
Change the length of the connecting rod can adjust the air tightness

无压风门

如结构图所示,两扇门A、B通过支撑臂及连杆C连成一个整体
当A向前运动时,另一扇门B在连杆的带动下向后运动,
这样打开风门的阻力F只有启动风门的气动力和重锤的重力,
因为风压差作用在风门A上的力等于作用在风门B上的力,而两力通过连杆相互抵消,故称为无压风门。

If the structure is shown in the picture, the two door A, B are connected into a whole through a supporting arm and a connecting rod C
When the A moves forward, another door B backward movement are driven by a connecting rod,
This opens the throttle resistance F only start aerodynamic force and gravity hammer,
Because the pressure difference at the door A force equal to the force on the door B,
And the two force through the connecting rod to offset each other, it is called a non pressure air door.

无压风门力平衡原理

无压(ya)风(feng)(feng)(feng)(feng)(feng)门(men)(men)采用(yong)压(ya)力(li)(li)平衡(heng)原理,通过四连杆(gan)机(ji)构(gou)及固定在门(men)(men)框上的(de)(de)限位装置实现两(liang)(liang)扇(shan)风(feng)(feng)(feng)(feng)(feng)门(men)(men)异向(xiang)同(tong)步开(kai)闭(bi),风(feng)(feng)(feng)(feng)(feng)门(men)(men)关(guan)(guan)闭(bi)后使(shi)两(liang)(liang)扇(shan)风(feng)(feng)(feng)(feng)(feng)门(men)(men)边的(de)(de)挡风(feng)(feng)(feng)(feng)(feng)皮子严(yan)密(mi)接(jie)触,具有良好的(de)(de)防漏风(feng)(feng)(feng)(feng)(feng)效果。由于(yu)(yu)作(zuo)用(yong)在风(feng)(feng)(feng)(feng)(feng)门(men)(men)上的(de)(de)矿(kuang)井负(fu)(fu)压(ya)通过连 杆(gan)机(ji)构(gou)转化(hua)为一种(zhong)内力(li)(li)并(bing)得(de)到平衡(heng),风(feng)(feng)(feng)(feng)(feng)门(men)(men)开(kai)关(guan)(guan)力(li)(li)的(de)(de)大小取决于(yu)(yu)重锤的(de)(de)重量(重锤重量一般(ban)在10kg~25kg之间)从而(er)保证了风(feng)(feng)(feng)(feng)(feng)门(men)(men)打开(kai)时(shi)省力(li)(li)、方便(bian) 灵活。如图2所(suo)示,由于(yu)(yu)两(liang)(liang)扇(shan)风(feng)(feng)(feng)(feng)(feng)门(men)(men)的(de)(de)面积大小近似相等(deng)(deng),则(ze)作(zuo)用(yong)在两(liang)(liang)扇(shan)风(feng)(feng)(feng)(feng)(feng)门(men)(men)上的(de)(de)矿(kuang)井负(fu)(fu)压(ya)也大小相等(deng)(deng),即(ji)F1≈F2,调整连杆(gan)机(ji)构(gou)是两(liang)(liang)扇(shan)风(feng)(feng)(feng)(feng)(feng)门(men)(men)紧密(mi)接(jie)触,风(feng)(feng)(feng)(feng)(feng)门(men)(men)处于(yu)(yu)关(guan)(guan)闭(bi)状态,则(ze)作(zuo)用(yong)于(yu)(yu)单扇(shan)上正反力(li)(li)矩相等(deng)(deng)。

Non pressure air door using the pressure balance principle, the four connecting rod mechanism and fixed on the door frame limiting device to realize the two air doors anisotropic synchronous opening and closing, close the throttle after the two fan door close contact with the skin, anti leakage effect is good. Due to the negative pressure in the air through the connecting rod mechanism into a kind of internal force and get the balance, door switch force depends on the size of the weight of the heavy hammer (hammer weight is generally 10kg ~ 25kg) so as to ensure the door open labor-saving, convenient and flexible. 无压风门
