The components and installation of the inner tube valve

A set of B-type and π-type metal valves assembled in the inner tube, including the following parts: valve tube with base; bridge-shaped gasket or circular gasket, which uses a nut to connect the inner tube wall, valve Compression pad and valve base (directly pressing with nuts may damage the rubber and biased rubber); bridge pad nuts; compression nuts, that is, when installing tires, the valves are inserted into the holes of the rim and the nuts Set on the valve (π-type valve does not have this nut); valve core; top cap.

The threads of the valves should be manufactured in the same way so that the nuts, top caps and valve cores can be replaced arbitrarily.

Install and fix the inner tube valve according to the following method: pass the valve cylinder through the perforation on the valve pad on the inner tube wall, the valve tube part must be exposed outside, and then put the bridge pad or gasket on the valve , and tighten the nut.

Because the valve pad and the valve base press the valve tube and the inner wall of the inner tube tightly together, the fixed part of the valve has proper airtightness.
