1所示的对夹式高压球阀的结构简图及采用的设计结构,本产品设计具有如下特点:

Chart 1 shows the structure diagram and the adopted design structure of the double-clip type high pressure ball valve. The design of this product has the following features:

1.      阀杆密封采用自主专利技术的(a) 球楔杆肩密封结构、(d)槽垫自密封结构和O型圈密封结构,使其在高压工况下不泄漏;

1. Valve rod seal adopts the independent patented technologies of (a) ball wedge shoulder pole leak proof structure, (b) slot pad leak proof structure and O-shape circle leak proof structure, which makes it not leak under high pressure.

2.      体盖连接亦采用自主专利技术的(b)槽垫自密封结构,即压力越高,密封性能越好;同时采用(c)榫槽防火密封结构,有效的保证了其在各种工况下的密封性能,介质不外漏;

2. The body cover also adopts independent patented technologies of (b) slot pad leak proof structure, which means if there is higher pressure, there is better sealing property; and (c) mortise fireproofing leak proof structure, which effectively guarantees its sealing property and allows no medium to leak.

3.      边法兰采用传统的(e-1)环连接结构或(e-2) 槽垫自密封结构(与平面法兰对接),实现与外法兰的无缝连接;

3. Side flange adopts traditional (e-1) loop connection structure design or (e-2) slot pad leak proof structure (butt joint with face flange), which realizes seamless connection with outer flange.

4.      对夹式结构设计球阀与法兰连接高压球(如图2所示)阀相比,具有明显的优势:     

4. Compared with high pressure ball valves connected by flanges, double-clip type ball valve has its own obvious advantages:

 

2  常用法兰连接高压球阀

Common high pressure ball valves connected by flanges

Ø       结构紧凑,安装维修方便;Compact structure , easy installation and maintenance

Ø       减少外漏点,保证密封性能;Reducing leaking sources, ensuring sealing property

Ø       减轻重量,降低成本。Reducing weight, lowering cost

DN50PN420高压球阀为例,对夹式结构

相对于法兰连接式结构,其重量减少50%

两者等比例模型如下图所示。

Set high pressure ball valves DN50 and PN420 as examples, double-clip is 50% lighter compared with flange-connected structure. The following is the models of the two with equal proportion.

对夹式结构还广泛的应用于各种通径、压力的阀门以及特殊要求阀门。如图所示分别为低压对夹式球阀与分体式法兰球阀,对夹式球阀同样具有结构紧凑,安装维修方便,减轻重量,降低成本等诸多优点。

Double-clip structure is also widely used in diameter valves, pressure valves and specially required valves. The following is the low pressure double-clip type ball valve and separated type flange ball valve respectively. The double-clip type ball valve also has the advantages of compact structure, easy installation and maintenance, reducing weight and lowering cost.
