Abstract

The invention provides an anti-explosion movable joint and a connecting nut mounting method thereof. The anti-explosion movable joint comprises a first joint part, a connecting nut arranged on the first joint body, a second joint part connected with the connecting nut in a threaded mode and a seal washer. The first joint part comprises a first joint body, a connecting wall, a connecting neck and a joint clamping ring, wherein the edge of one end of the first joint body inwards extends to form the connecting wall in the radial direction, the end of the connecting wall outwards extends to form the connecting neck in the axial direction, and the end of the connecting neck outwards extends to form the joint clamping ring in the radial direction. One end of the connecting nut is provided with a nut clamping ring formed by the means of the method the connecting nut inwards extends in the radial direction, the connecting neck is sleeved with the nut clamping ring, and the nut clamping ring and the joint clamping ring are hooked with each other. Under the condition that the thread sizes of the first joint part and the second joint part are changed, it is ensured that the sizes of the connecting nut and a thread thereof are not changed, so that production materials are saved, and production cost is lowered.

Description

technical field [0001] The invention relates to an installation method of an explosion-proof movable joint and a connecting nut thereof. Background technique [0002] The explosion-proof joint in the prior art, as shown in the patent document CN201448766U, includes a first joint, a connecting nut arranged on the first joint, a second joint threadedly connected with the connecting nut, a set For the sealing gasket between the first joint and the second joint, the joint clasp is directly formed by extending radially outward from the end of the first joint. Due to the different external dimensions under different environmental requirements, when the outer diameter of the first joint becomes larger, the size of the connecting nut needs to be increased simultaneously, resulting in more parts and specifications, more materials used for production, and lower production costs. high. Contents of the invention [0003] The technical problem to be solved by the present invention is...
