When the rotating handle is located at the second position, the password assembly is unlocked, and the key and the key groove are combined. The valve has the advantage of being good in anti-theft performance.
Description
Technical field
The utility model relates to a kind of valve for guarding against theft.
Background technique
Valve has gate valve, and butterfly valve turns core valve, ball valve etc., and valve is generally to carry out switch by the mode of rotation.In the valve seat of these valves, be provided with fluid passage, be provided with valve plate in fluid passage, valve plate is connected with valve rod, thereby rotary valve rod regulates the angle of swing of valve plate, opens or throttle down.The shortcoming of these valves is: theftproof performance is poor, and anyone only needs rotation valve rod can open or close valve.Even if some users lay down the manual rotation part of valve rod or lock and pinned, only also can, by valve open, therefore, in some occasions phenomenon that often generation is stolen by illegally opening valve, cause heavy losses to valve user with simple instrument.
Summary of the invention
In order to overcome the now poor shortcoming of valvular theftproof performance, the utility model provides the valve that a kind of theftproof performance is good.
Mechanical puzzle valve for guarding against theft, comprises valve seat, and valve rod and valve plate are provided with fluid passage in valve seat, and valve plate is arranged in fluid passage, and valve plate makes the entrance and exit of fluid passage connect or separate, and valve rod is fixedly connected with valve plate;
It is characterized in that: cipher lock is installed on valve seat, and cipher lock comprises the lock housing fixing with valve seat, is provided with turning handle in lock housing the baffle ring of holding turning handle and the first spring, and code component; Turning handle is connected by key and keyway detached type with valve rod; Baffle ring is fixedly connected with lock housing, and the first spring is positioned on baffle ring, and the first spring is between baffle ring and valve rod;
Lock housing one side is provided with side cover and post lid, and side cover, post lid and lock housing surround the holding cavity that holds code component, and code component comprises traveller, gear handle and multiple code pins; Traveller is provided with multiple pin-and-holes, is equipped with a code pins in each pin-and-hole; Between each code pins and lock housing, be provided with the second spring, code pins has the extension that exposes to side cover; In each code pins, offer circular groove; When code component is locked, the circular groove of at least one code pins and the dislocation of the pin-and-hole of traveller; When code component release, the pin-and-hole contraposition of the circular groove of all code pins and traveller;
Traveller is fixedly connected with gear handle, and lock housing is provided with for the through hole that passes of gear handle, and turning handle is provided with annular groove, gear handle insert in annular groove and with annular groove Spielpassung; Turning handle is in the time of primary importance, and code component is locked, and key and keyway depart from; Turning handle in the time of the second place, code component release, key is combined with keyway.
Further, code pins is divided into two kinds of pins, and two kinds of pins, by body and extension composition, form step between extension and body, and the second spring is in the time of Pre strained state, and this step props up side cover; Circular groove is opened on body, and the circular groove of the first pin and the distance of extension are less than the circular groove of the second pin and the distance of extension;
Lock housing is provided with the receiving cavity that holds the second spring, and insert in receiving cavity the inner of code pins, has respectively positioning ring in each receiving cavity, when the first pin pushes against positioning ring, and the pin-and-hole contraposition of its circular groove and traveller.Because the extension of code pins exposes to side cover, therefore, one end of extension is as the outer end of code pins, and the other end is as the inner of code pins.
Further, lock housing has the extension part of holding traveller, is provided with the 3rd spring between traveller and extension part.
Further, keyway is arranged on turning handle, and key is arranged on valve rod.
Further, the holding cavity between side cover and lock housing and traveller Spielpassung, side cover is provided with exhaust port; Side cover is fixed by post lid and lock housing, and post lid one end and lock housing are fixed, and the other end and side cover are fixed, and post cap seal closes the top of holding cavity.
Further, side cover is provided with the locating slot coordinating with code pins, and each locating slot is corresponding with a code pins, and the body outer end of code pins is positioned at locating stud.
Further, lock housing top is fixed with gland, and turning handle part exposes to gland, and the portion of exposing of turning handle is provided with rotation section.Rotation section can be to make prismaticly, can be also that handwheel is fixed on turning handle as rotation section.
Further, the annular saddle that baffle ring comprises cylinder ring and extends internally, the first spring is positioned on annular saddle.
When the utility model work, the second pin keeps initial position, all the first pins are inwardly pressed simultaneously, in the time that the inner of the first pin props up positioning ring, the pin-and-hole of its circular groove and traveller is completely overlapping, traveller moves down, make pin-and-hole and circular groove axially occur dislocation, be that traveller inserts in circular groove, now, turning handle is pressed downwards, turning handle drives gear handle, gear handle moves down together with traveller, the first spring and the second spring are compressed, until the keyway of turning handle and the bond of valve rod are closed, turning handle rotates and can be with ovable valve stem to rotate, realize the opening and closing of valve.
In the time that valve need to be locked, unclamp turning handle, make turning handle get back to primary importance from the second place, the first spring and the second spring reset, traveller is got back to initial position, and the keyway of turning handle and the key of valve rod depart from.Because traveller resets, the pin-and-hole of traveller and circular groove are again completely overlapping, now, the first pin resets under the effect of the 3rd spring, the circular groove dislocation of the circular groove of the second pin and the first pin, the first pin part enters in the pin-and-hole of traveller, and traveller is blocked by the first pin, cannot slide up and down.The state of valve cannot be adjusted.
Can on the extension of code pins, number designation be set, form password.By changing the order of the first pin and the second pin, can obtain different passwords, realize the encryption to valve.
The utlity model has the advantage that theftproof performance is good.
