Abstract

The utility model discloses a pipeline valve. According to the principle of the suction and the repulsion of magnetic force, magnetic material is manufactured into a lock tongue which is embedded in grooves of a lock core and a lock body; the lock core is fixedly connected with a valve core; the lock tongue is caused to move through a magnetic key, and the lock core and the valve core are controlled to rotate to make the valve opened and closed. The utility model can be used for the lock control of the opening of valves of transmission pipelines of water supply, power supply, gas supply, etc. The utility model uses the form of double lock and has the advantages of high security, reliable lock, incapability of being opened without a special key, simple structure, convenient operation, reliable performance, no rustiness, firmness and high durability; the utility model is entirely made of copper material.

Description

The pipeline locking-valve

The utility model relates to a kind of pipeline valve with lock, is furtherly to disclose a kind of pipeline locking-valve, belongs to the mechanical pipe valve technology field.

At present, in public utilitieies such as heating, air feed, water supply by pipeline with gas, water paid flow to the user, therefore, just can not only rely on valve to control its use during supplied goods, need the valve locking is got up toward contact, prevent from illegally to usurp.Normally with common lock valve handle is pinned, control its unlatching, not enough place is that lockhole easily stops up corrosion, and tapered end is easily pried open by the people.

The utility model discloses a kind of pipeline valve, has solved the problem of existing valve with lock control, has increased the unlatching difficulty of the block of valve.

Solution of the present utility model is as follows: become the utility model by valve body, spool, lock body, lock core, gland, magnetic dead bolt and set of keys, the top of valve body is lock body, the spool device is in valve body, lock core is enclosed within the lock body, be locked by gland, evenly offer groove on lock core, the lock body, the magnetic dead bolt is embedded in the groove, and can be in groove inside and outside the slip, make lock core location or rotate, utilize the magnetic principle of inhaling mutually, repel each other, correspondingly be equipped with magnetic key, make the dead bolt adhesive by magnetic key, reach the purpose of control valve.

Good effect of the present utility model is: utilize magnetic principles, by the tonguing of magnetic key operated lock, the control lock core opens and closes, and finishes pipeline management, can be widely used in supplying water, the valve opening lock control of conveyance conduits such as power supply, air feed.This locking-valve adopts dual locking form, strong security, and locking is reliable, and no private key can't be opened.

Fig. 1 is the utility model valve body structure schematic diagram.

Fig. 2 is the utility model valve A-A view.

Fig. 3 is the utility model Key structure schematic diagram.

Further specify the utility model below in conjunction with accompanying drawing: with reference to Fig. 1, Fig. 2, the top of valve body 1 is lock body 22, spool 8 devices are in valve body 1, lock core 2 is enclosed within the lock body 15, be locked by gland 3, have two axisymmetric grooves 7 and groove 11 on lock core 2 surfaces, also offering two grooves 5 and groove 9 on the lock body 15 with on the groove relative position of lock core 2, magnetic sheet 10 and two plots of opposite grooves 11 that are embedded in respectively of magnetic dead bolt 4 polarity, in 9, and can be at groove 11, the inside and outside slip in 9, the length of magnetic dead bolt 4 is not higher than lock core 2 edges in the groove 11 of lock core 2 time and is as the criterion, to guarantee that dead bolt 4 is when the same magnetic of the magnet 13 of key 12 slips into groove 11 under repelling, lock core 2 can rotate in lock body 15, and valve body 8 is opened and closed.Magnetic dead bolt 6 in being embedded in groove 5, under attracting, enters groove 7 at opposite magnetic with opposite magnetic, and lock core 2 can not be rotated, and reaches the locking purpose.The length of magnetic dead bolt 6 is not higher than the edge of valve body in the groove 5 of valve body 1, when slipping into groove 5 under the opposite magnetic attraction with the magnet 14 of assurance dead bolt 6 in key, lock core 2 can rotate in valve body 1, and valve body 8 is opened and closed.

With reference to Fig. 3, key 12 is the cylindrical outside that is enclosed within lock body 15, and its bottom is inlaid with two blocks of magnetic to opposite axisymmetric magnet 14 and magnet 13.

In implementation process, the

groove

5,7,9,11 on lock core 2 and the lock body 15 also can be offered separately respectively, and can adopt the setting of different azimuth on locking-valve is axial, to satisfy the monotony that locking-valve is opened; Magnetic

dead bolt

4,6 according to magnetic to different permutation and combination enough become many group installation forms, the magnet of inlaying on the key 12 13,14 is also adjusted with it accordingly and is installed simultaneously.
