进口斜面球阀德国洛克品牌质量可靠

进口斜面球阀结构特点：

1、独特的结构密封更加可靠斜面球阀又称“楔式球阀”，采用整体上装式新型结构。两阀座密封面设计成楔形两斜面，球体上部有一弹簧。在弹簧力的作用下，阀座密封面与球体紧密贴合，形成可靠的密封。

2、阀杆凸肩结构保证了上密封性能阀杆下端设有凸肩，可在阀体内压异常升高时，防止阀杆脱出。在弹簧及介质力的作用下，阀杆   凸肩压紧垫片，形成上密封效果。

3、先进的防火、防静电结构在球体与阀座之间设置有防火金属环。在意外火灾阀座烧损后，金属环压在球体上起到密封作用。确保系统的安全，防止重大事故发生。球体上部的予紧弹簧可将球体与阀座摩擦产生的静电，经导线导入地下。防止因静电产生的火花点燃易燃易爆介质，保证系统的安全。

4、阀门的启、闭力小，安装、维修方便阀杆填料函的密封采用填料平面与阀杆凸肩、

阀盖平面的压紧，靠弹簧的予紧力及上压盖的压紧力实现密封。减轻了阀门的启、闭力。阀门采用整体上装式结构，只须将上部阀盖拆开，既可取出阀门体内全部零件,便于阀门的维修和更换。

进口斜面球阀参数：

进口斜面球阀产品优点：

一、耐磨；由于硬密封球阀的阀芯是合金钢喷焊，三片式球阀 密封圈是合金钢堆焊，所以硬密封球阀在开关时不会产生太大的磨损。（它的硬度系数为65-70）：

二、密封性能好；由于硬密封球阀的密封是采用人工研磨，直到阀芯与密封圈完全吻合才能使用。所以他的密封性能是可靠的。

三、开关轻；由于硬密封球阀的密封圈底部采用弹簧使密封圈与阀芯紧紧抱在一起，所以在外界力量超过弹簧的预紧力时开关非常轻。

四、使用寿命长：已广泛应用于石油、化工、发电、造纸、原子能、航空、火箭等各部门，以及人们日常生活中。

Advantages of imported beveled ball valve:
1、 Wear resistance: because the valve core of hard seal ball valve is alloy steel spray welding, and the sealing ring of three piece ball valve is alloy steel surfacing welding, the hard seal ball valve will not have too much wear when it is opened and closed. (its hardness coefficient is 65-70)
2、 Good sealing performance; as the hard sealing ball valve is sealed by manual grinding, it can only be used until the valve core and sealing ring are completely consistent. So his sealing performance is reliable.
3、 The switch is light; because the bottom of the seal ring of the hard seal ball valve uses a spring to tightly hold the seal ring and the valve core together, the switch is very light when the external force exceeds the preload of the spring.
4、 Long service life: it has been widely used in petroleum, chemical industry, power generation, paper making, atomic energy, aviation, rocket and other departments, as well as people's daily life.

进口斜面球阀产品简介：

德国洛克《DE LOCKE》采用楔式上装型，其球体上施加一压缩弹簧，压缩弹簧的作用是在球体上施加预紧力，使阀座密封面在任何情况下都紧密接触，密封性能好。阀座与阀体接触面的楔角为 10°，阀座能够自锁，当阀座受到较大的压力时，阀座不会产生任何位移。故这种结构的阀门既有闸阀的特点又有球阀的优点。

Brief introduction of imported beveled ball valve products:
German rock "de lock" adopts wedge-shaped top mounted type. A compression spring is applied on the ball. The function of the compression spring is to apply preload on the ball, so that the sealing surface of the valve seat can be in close contact under any circumstances, and the sealing performance is good. The wedge angle of the contact surface between the valve seat and the valve body is 10 ° and the valve seat can be self-locking. When the valve seat is under greater pressure, the valve seat will not produce any displacement. Therefore, the valve with this structure has both the characteristics of gate valve and the advantages of ball valve.
