A combined type of metal wound gasket, including the inner and outer ring, sealing components, sealing component consists of a flexible sealing strip and annular annular strip, and the flexible sealing strip is overlapped and sandwiched between the inner ring and the outer ring; the outer ring is composed of left and right half ring ring, both ends right ring and a connecting sheet molding, a molding ring notch at both ends of the right, the right half ring connecting piece is inserted in the slot in the inner ring and right through riveting together; the outer ring of the inner ring on both sides forming a number of insert, left half ring and the right ring are inserted type and relative slot, insert the inner sealing component is inserted in the slot through the left half ring or the inner ring and the right and left or right half ring rivet ring riveted together. The utility model is provided with a corresponding connecting structure on the inner ring and the outer ring of the metal winding gasket, and the welding process can be omitted when assembling, which is convenient for the assembly of the metal winding sealing pad, and the assembly efficiency and the production efficiency are improved.
【技术实现步骤摘要】
:本技术涉及密封垫的
,更具体地说涉及一种组合式的金属缠绕密封垫。
技术介绍
:目前在一些化工、制药的产业中,其药液通过管道进行输送,而其管道一般为拼接的管道,相拼接的管道之间采用具备较好弹性和密封性的缠绕密封垫进行密封。现有的缠绕密封垫一般由内环、外环以及内环、外环之间的密封组件,其密封组件一般由呈V型的并层叠的石墨带和钢带组成,而钢带绕置到内环后其钢带的两端需要焊接,同时还需要将外环固定在最外层的钢带上,而外环一般两个半环组成,则由需要通过焊接实现连接,其缠绕密封垫的装配较为麻烦,且装配的效率不高。
技术实现思路
:本技术的目的就是针对现有技术之不足,而提供了一种组合式的金属缠绕密封垫,其采用连接件代替焊接方式实现金属缠绕密封垫的装配,提高了装配效率。一种组合式的金属缠绕密封垫,包括内环、密封组件和外环,密封组件由若干环形的钢带和环形的柔性密封带组成,钢带和柔性密封带呈交错层叠并夹持在内环和外环之间;外环由左半环和右半环组成,右半环的两端成型有连接片,右半环的两端成型有与右半环上连接片相对的槽口,右半环的连接片插接在右半环的槽口内并通过铆钉铆接在一起;所述内环两侧的外圈上成型有若干插片,左半环和右半环上均成型有与插片相对的插槽,内环的插片穿过密封组件插接在左半环或右半环的插槽内并通过铆钉和左半环或右半环铆接在一起。所述内环和外环均呈方形,内环和外环的厚度相等,内环的厚度小于密封组件上钢带或柔性密封带的宽度。所述密封组件上的钢带或柔性密封带的横截面呈V型或W型,钢带和柔性密封带的宽度相等,所述的柔性密封带采用石墨材质。所述内环的插片上、左半环的插槽处和右 ...
