Abstract
The utility model discloses a locking mechanism of a valve body. The locking mechanism comprises a bonnet and a valve rod which is connected into the bonnet, wherein a locking screw is arranged between the bonnet and the valve rod, as for improvement, a rotatable locking cap is arranged on the bonnet, a key body which is matched with the locking cap is arranged on the locking cap, at least one pair of matching lockholes is respectively arranged at the corresponding parts of the matching end surfaces of the locking cap and the bonnet, a lower magnetic steel which locks the locking cap with the bonnet and an elastic part which keeps the lower magnetic steel be locked with another lockhole are arranged in one lockhole, and an upper magnetic steel which is matched with the lower magnetic steel for unlocking is arranged on the key body which is matched with the locking cap. The locking cap is arranged on the bonnet, the lockholes and the lower magnetic steel are arranged between the locking cap and the bonnet, the key body which has the upper magnetic steel is used to drive the lower magnetic steel, so the bonnet is opened or locked. The locking mechanism is convenient and reliable to lock and open.
Description
Technical field
The utility model relates to a kind of valve body locking mechanism.
Background technique
The locking valve that is widely used in hot and cold water, hot duct has the unique function that can close and can not open arbitrarily, and unlatching needs specific key.Present locking valve mainly is through magnetic principles control, and existing this locking valve complex structure, cost are high relatively, and it is unreliable to control.
Summary of the invention
The utility model provides a kind of valve body locking mechanism of being convenient to sealed unlatching for solving the problem that existing technology in use exists.
The technological scheme that the utility model solves existing issue is: a kind of valve body locking mechanism; Comprise valve gap, be connected in the valve rod in the valve gap, be provided with locking nut between valve gap and the valve rod; As improvement; Described valve gap is provided with a rotating locking closure, and locking closure is provided with it the key body that cooperates, and the corresponding position is provided with the lockhole that at least one pair of matches mutually between described locking closure and the end face that valve gap matches; Be provided with the lower magnetic steel of sealed locking closure and valve gap in the described lockhole and keep lower magnetic steel and the sealed elastic member of another lockhole, described key body with the locking closure cooperation is provided with the upper magnetic steel of the release that matches with lower magnetic steel.
As further improvement, described lower magnetic steel and elastic member are arranged in the lockhole set on the valve gap, the sealed lockhole of pairing mutually of described lower magnetic steel.
As further improvement, described locking closure lockhole corresponding part protrudes from locking closure, and described key body corresponding part is provided with groove, and described upper magnetic steel is arranged in the groove.
As further improvement, described four lockholes are the crosswise protrusion and are arranged on the locking closure, and described key body corresponding part is provided with and is criss-cross groove, and upper magnetic steel is arranged in the groove.
As further improvement, described locking closure is socketed on the valve gap, is provided with back-up ring between locking closure and the valve gap sidewall.
The utility model compared with prior art, its beneficial effect is that a locking closure is set on valve gap; Be provided with lockhole and lower magnetic steel between locking closure and the valve gap; Through one have upper magnetic steel key body drive lower magnetic steel, open or Lock closing valve cover, the sealed unlatching of the utility model is convenient and reliable.
