良工阀门的链接要注意什么?

活套法兰连接:这是良工阀门中用得较多的连接形式。按结合面形状又可分为以下几种:

Loop flange connection: This is a commonly used connection form in Lianggong valves. According to the shape of the joint surface, it can be further divided into the following types:

1、光滑式:用于压力不高的阀门。加工比较方便。

1. Smooth type: used for valves with low pressure. Processing is relatively convenient.

2、凹凸式:工作压力较高,可使用中硬垫圈。

2. Convex convex type: With high working pressure, medium hard washers can be used.

3、榫槽式:可用塑性变形较大的垫圈,在腐蚀性介质中使用较广泛,密封效果较好。

3. Mortise and tenon type: gaskets with large plastic deformation can be used, which are widely used in corrosive media and have good sealing effects.

4、梯形槽式:用椭圆形金属环作垫圈,使用于工作压力≥64公斤/平方厘米的阀门,或高温阀门。

4. Trapezoidal groove type: using elliptical metal rings as washers, used in valves with a working pressure of ≥ 64 kg/square centimeter or high-temperature valves.

5、透镜式:垫圈是透镜形状,用金属制作。用于工作压力≥100公斤/平方厘米的高压阀门,或高温阀门。

5. Lens type: The gasket is in the shape of a lens and is made of metal. Used for high-pressure valves or high-temperature valves with a working pressure of ≥ 100 kg/square centimeter.

6、O形圈式:这是一种较新的法兰连接形式,它是随着各种橡胶O形圈的出现,而发展起来的,它在密封效果上比一般平垫圈可靠。

6. O-ring type: This is a relatively new flange connection form that has developed with the emergence of various rubber O-rings. It is more reliable in sealing than ordinary flat washers.

螺纹连接:这是一种简便的连接方法,常用于小阀门。又分两种情况:

Thread connection: This is a convenient connection method commonly used for small valves. There are two further situations:

1、直接密封:内外螺纹直接密封。为了保证接头不渗漏,经常用铅油、麻和聚四氟乙烯基原料带填充;其中,聚四氟乙烯原料带应用广泛;这种材料耐腐蚀性好,密封性效果非常不错,使用保存方便,拆卸时可以完全去除,因为是不粘膜,比铅油和线麻优越很多。

1. Direct sealing: The internal and external threads are directly sealed. To ensure that the joint does not leak, lead oil, hemp, and polytetrafluoroethylene based raw materials are often used for filling; Among them, polytetrafluoroethylene raw materials are widely used; This material has good corrosion resistance, excellent sealing effect, and is easy to use and store. It can be completely removed during disassembly because it is non adhesive and much superior to lead oil and hemp.

2、间接密封:螺纹拧紧的力传递到两个平面之间的垫片上,使垫片起到密封作用。

2. Indirect sealing: The force of tightening the thread is transmitted to the gasket between two planes, making the gasket play a sealing role.
