Abstract
Encrypt valve and special spanner before the utility model discloses a kind of effective table, encrypt the locking-valve device that valve comprises valve seat, gate valve mechanism, band pin-shifting hole before the table, described locking-valve device comprises in the lockhole that the magnetic support that is connected by driving pin with the valve rod of gate valve mechanism, the turncap that is arranged on gate valve mechanism more than at least one group and magnetic support be complementary and has the lock pearl assembly of magnet steel, is installed in the outer dust cover of magnetic support, described special spanner is provided with finger and the powerful magnet steel that matches mutually with the pin-shifting hole and the magnet steel of locking-valve device, and the pole polarity of the adjacent end of two pairing magnet steel is identical.The utility model adopts the contactless mode of unblanking, and the principle of unblanking is difficult for being grasped by the user, uses the preceding valve of encrypting of the also restive table of improper instrument, reaches the purpose of control break-make water effectively.
Description
Technical field
The utility model relates to preceding valve of a kind of table and opening device.
Background technique
Valve is to be used for controlling the break-make that supplies water in the water meter upstream before the table, at present, be widely used in the preceding valve of table on the pipeline, its locking mode (as traditional valve switch, special-purpose mechanical lock and the key of use) is very simple, the principle of unblanking is easily grasped by the user, valve is easy to be controlled by improper instrument before causing showing, and can't reach the purpose of control break-make water effectively, give the non-management person privately the dismounting water meter provide may.
The model utility content
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and a kind of effective table preceding encryption valve and special spanner that utilizes magnet steel to encrypt is provided, and the possibility of valve before the improper instrument control table of eliminating use is protected the administration authority of showing preceding valve effectively.
For achieving the above object, encrypt valve and special spanner before the effective table of the present utility model, encrypt valve before the table and comprise valve body, gate valve mechanism, locking-valve device, described locking-valve device comprises in the lockhole that the magnetic support that is connected by driving pin with the valve rod of gate valve mechanism, the turncap that is arranged on gate valve mechanism more than at least one group and magnetic support be complementary and has the lock pearl assembly of magnet steel, is installed in the outer dust cover of magnetic support, wherein, be equipped with two pin-shifting holes that are complementary on magnetic support and the dust cover; Described special spanner is provided with two fingers, and two pin-shifting holes on its position and external diameter and magnetic support and the dust cover are complementary, in spanner, also be fixed with magnetic support in the powerful magnet steel that matches mutually of magnet steel, the pole polarity of the adjacent end of two pairing magnet steel is identical.
Working procedure of the present utility model is: in the two fingers insertion dust cover and the pin-shifting hole on the magnetic support with spanner, utilize the pole polarity of the interior adjacent end of magnet steel of interior powerful magnet steel of spanner and magnetic support identical, mutually exclusive, lock pearl assembly in the valve before the table is pushed away locked position, valve is opened or locked to rotating spanner.
As further improvement of the utility model, the described lock pearl assembly that is arranged in the turncap of gate valve mechanism and the lockhole that magnetic support is complementary and has a magnet steel comprises magnet steel, shotpin and spring, wherein, the lockhole end face of turncap and magnetic support becomes the gap to be provided with, magnet steel and spring place the lockhole of magnetic support and turncap respectively, shotpin places lockhole simultaneously, and the external diameter of magnet steel is greater than the aperture of turncap lockhole, the advantage of this kind structure is: when shotpin is pushed in the lockhole of turncap, magnet steel can not enter in the lockhole of turncap, the fixing shotpin that uses is controlled relatively rotating of magnet steel and turncap, has increased the reliability of locking-valve device.
As further improvement of the utility model, dust cover is installed in outside the magnetic support by two pins under the turncap flange, and dust cover can rotate around the center.
In sum, the utility model adopts the contactless mode of unblanking, and the principle of unblanking is difficult for being grasped by the user, uses the preceding valve of the also restive table of improper instrument, reaches the purpose of control break-make water effectively.
