进口水用闸阀
进口水用闸阀概述：
闸阀关闭时，密封面可以只依靠介质压力来密封，即只依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封，这就是自密封。大部分闸阀是采用强制密封的，即阀门关闭时，要依靠外力强行将闸板压向阀座， 以保证密封面的密封性。其运动方式：闸阀的闸板随阀杆一起作直线运动的，亦叫明杆闸阀。通常在升降杆上 有梯形螺纹，通过阀门顶端的螺母以及阀体上的导槽，将旋转运动变为直线运动 , 也就是将操作转矩变为操作推力。开启阀门时，当闸板提升高度等于阀门通径的1：1倍时，流体的通道完全畅通，但在运行时，此位置是无法监视的。实际使用时，是以阀杆的顶点作为标志，即开不动的位置，作为它的全开位置。为考虑温度变化出现***现象 , 通常在开到顶点位置上 , 再倒回 1/2－1圈 , 作为全开阀门的位置。因此 , 阀门的全开位置，按闸板的位置（即行程〉来确定。有的闸阀阀杆螺母设在闸板上，手轮转动带动阀杆转动，而使闸板提升，这种阀门叫做旋转杆闸阀或叫暗杆闸阀。
进口水用闸阀产品性能参数：
产品名称：进口高压闸阀
规格范围：DN15-DN1200 
温度范围：-20℃≈350℃
压力范围：PN64
阀体材质：铸钢/不锈钢/耐高温钢
连接方式：手动
产地：德国
产品品牌：德国Orsen奥尔申
进口水用闸阀优点：
1、流动阻力小。阀体内部介质通道是直通的，介质成直线流动，流动阻力小。
2、启闭时较省力。是与截止阀相比而言，因为无论是开或闭，闸板运动方向均与介质流动方 向相垂直。
3、高度大，启闭时间长。闸板的启闭行程较大，降是通过螺杆进行的。
4、水锤现象不易产生。原因是关闭时间长。
5、介质可向两侧任意方向流动，易于安装。闸阀通道两侧是对称的。
6、结构长度(系壳体两连接端面之间的距离)较小。
7、形体简单 , 结构长度短，制造工艺性好，适用范围广。
8、结构紧凑，阀门刚性好，通道流畅，流阻数小，密封面采用不锈钢和硬质合金，使用寿命长，采用PTFE填料．密封可靠．操作轻便灵活．

Imported water valve
Imported water valve Overview:
When the valve is closed, the sealing surface can only rely on media pressure to seal, that is, only the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most of the valve is sealed by force, that is, when the valve is closed, to rely on external pressure to force the gate valve to ensure the tightness of the sealing surface. Its movement: gate valve with the valve stem linear motion, also called clear shot valve. Often movements are trapezoidal threaded rod through the top of the valve guides and valve nut on the rotary motion into linear motion, which is the operating torque thrust into action. Open the valve, when the gate valve lift height equal to the diameter of the 1: 1 times, the fluid channel is completely ***ooth, but at run time, this position is not monitored. Actual use, is the apex of the stem as a sign that the fixed position, as its fully open position. Temperature appears to c***ider locking phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as the position of the valve fully open. Therefore, the fully open position of the valve, according to gate position (ie, tr***el> to determine. Some valve stem nut is located at the gate, handwheel drive stem rotation, le***ing the gate to upgrade, this valve is called rotating rod valve or valve called the dark bar.
Imported water valve product performance parameters:
Product Name: imported high-pressure valve
Specificati*** Range: DN15-DN1200
Temperature range: -20 ℃ ≈350 ℃
Pressure range: PN64
Body material: steel / stainless steel / high-temperature steel
Connection: Manual
Origin: Germany
Brand: Germany Orsen Orr Shen
Imported water valve advantages:
1, ***all flow resistance. Body internal media channel is straight, medium into a linear flow, ***all flow resistance.
2, more effort when opening and closing. In contrast with the shut-off valve, since either open or closed, the shutter movement direction are perpendicular to the flow direction of the medium.
3, height, long opening and closing times. Gate opening and closing stroke of a larger drop is carried out by a screw.
4, easy to produce water hammer phenomenon. The reason is that long off time.
5, the media can flow in any direction to both sides for easy installation. Channel is symmetrical on both sides of the gate valve.
6, the structure length (the distance between two lines between the connecting end of the housing) is ***all.
7, simple shape, structure, length short, good manufacturing processes for a wide range.
8, compact structure, the valve rigid, channel flow, flow resistance ***all number, the sealing surface of stainless steel and tungsten carbide, long service life, the use of PTFE packing. Reliable sealing. Lightweight and flexible operation.
