At body lockhole.
It is further improved to be：Simultaneously provided with O-shaped groove, movable span and lockhole at the valve body water outlet upper end.
It is further improved to be：Described removable pin one end is provided with inside locating slot, the removable pin and is additionally provided with holddown spring.
By using preceding solution, the beneficial effects of the utility model are：This novel improved type multifunctional non-return valve,
Flap side is fixed on and using threaded connection in described removable pin one end, and the other end passes through valve body water outlet upper end, using removable pin
The rapid circulation prevented or close medium is designed to, prevents water side leakage from causing the waste at water source, the spring is located at valve
Internal portion simultaneously passes through removable pin, and design spring can mitigate impact of the medium to valve element, with noise reduction shock effect,
The service life to valve element can be improved again, the closing of flap can be aided in again, provided with O-shaped between the removable pin and valve body
Sealing ring, the phase magnet is at valve body lockhole.
Simultaneously provided with O-shaped groove, movable span and lockhole at the valve body water outlet upper end, described removable pin one end is provided with positioning
Holddown spring is additionally provided with inside groove, the removable pin, the effect of its locating slot is that phase magnet is blocked locating slot plays pass
The effect of closing.
Operation principle：When valve is intake, water slowly opens flap under the action of the spring, and at this moment removable pin is also and then past
Outer activity, this valve has been switched on, when water inlet end is anhydrous, and the rapid backwater of backwater end is by flap slowly closing under the action of the spring
Sealing, if finding water outlet rear end pipe leakage in normal water flowing, you can down shift removable pin onto position rapidly, passing through magnet
The principle of effect homopolar-repulsion phase magnet is shifted onto to block in the locating slot in removable pin can close check-valves rapidly, this
Effect is very good, and the waste at water source can be prevented again, is that user and society bring good economic benefit.
