Abstract

The utility model relates to a magnetic locking valve, improving the opening and closing parts of a locking valve and solving the deficiency that the locking valve in present market can be easily stolen and broken because the opening and closing parts of the locking valves lack the protection function. The utility model is characterized in that a pin hole and an internal hollowness are arranged at a plastic valve body; a copper valve rod is arranged in the plastic valve body; a plurality of springs and magnetic pins are arranged in the pin hole in order; a copper locking cap is pressed in the internal hollowness at the plastic valve body and is connected with the copper valve rod by steel pins; the magnetic pins are arranged at the magnetic pin hole at a key handle; a wrench is arranged at the key handle. The utility model has the advantages of less liability to be easily broken and stolen due to the protection function of the opening and closing parts, rust prevention and prolonged service life since part elements are made of plastic materials.

Description

The magnetic locking valve

Technical field;

The invention is the improvement to locking valve open and close position structure.

Background technique:

Present locking valve on the market, the open and close structure is all protruded outside valve body, the unprotect device, easily destroyed and stolen open and close loses the locking effect, has locking valve in the market to adopt materials such as full cast iron, copper, stainless steel again; Adopt cast iron, easy-to-rust, working life lack; Though adopt copper, stainless steel can increase the service life but the price height, has increased user's burden.

Summary of the invention:

The purpose of the invention provides a kind of protective function that has, magnetic locking valve with low cost; The purpose of the invention is to realize by following technological scheme: valve body is made the plastics valve body, on the plastics valve body, make the pellet shot from a slingshot hole and in recess, the copper valve rod is installed in the plastics valve body, make pin-and-hole at copper valve rod upper end, spring is installed in the pellet shot from a slingshot hole, magnetic marble is installed on the spring, make the recess that cooperates with the copper valve rod below the copper lock nut, on the recess wall, make pin-and-hole, on the outward edge of recess, make locking cap opening, on the copper lock nut middle part make polygon in recess, the copper lock nut is fitted in the interior recess on the plastics valve body, steel pin is installed in the pin-and-hole on copper valve rod and the copper lock nut, make magnetic marble hole and polygon outer lug boss on the shank of the key, to go up magnetic marble and be installed in the magnetic marble hole, spanner will be installed on the shank of the key, the shank of the key will be placed on the copper lock nut.

The invention operation instruction: when being installed in the copper lock nut in the interior recess on the plastics valve body, spring is to be compressed in the pellet shot from a slingshot hole, under the effect of spring, the magnetic marble Lower Half is stayed in the pellet shot from a slingshot hole, the first half is stayed in the magnetic marble hole on the copper lock nut, this moment, locking valve was in original state, promptly close state, when the shank of the key being placed on the copper lock nut, recess matches in polygon on polygon outer lug boss on the shank of the key and the copper lock nut, this moment, magnetic marble was identical with last magnetic marble polarity, magnetic marble in the magnetic marble hole on the copper lock nut is all repelled in the pellet shot from a slingshot hole on the plastics valve body, pull spanner, drive the shank of the key and rotate, recess cooperates in the shank of the key polygon on polygon outer lug boss and copper lock nut, drive the copper lock nut and rotate, the copper lock nut is connected with steel pin with the copper valve rod, therefore drives the copper valve rod and rotates, this moment, locking valve was non-original state, promptly opened state.

The advantage of the invention: lock structure in the copper lock nut is fitted in the plastics valve body, must be needed special-purpose open and close key and could realize open and close, so the magnetic locking valve has protective function, be difficult for destroyedly, be difficult for stolen open and close; Owing to adopt plastics valve body and copper open and close structural member, make the magnetic locking valve promptly antirust, increase the service life, reduce cost, alleviate user's burden again.

Fig. 2 is the member separated state schematic representation of magnetic locking valve.

Embodiment:

Magnetic locking valve: comprise plastics valve body 8, copper valve rod 9, spring 6, magnetic marble 5, copper lock nut 4, steel pin 12, the shank of the key 2, go up magnetic marble 3, spanner 1 formation; Adopt PPR, U-PVC made valve body, the quantity of making pellet shot from a slingshot hole 7, pellet shot from a slingshot hole on the plastics valve body can be designed to even number according to the volume of plastics valve body, makes interior recess at the top; It is prior art that the lower end spheroid of making pin-and-hole 10, copper valve rod at copper valve rod upper end cooperates with the plastics valve body; The recess that cooperates with the copper valve rod is made at the middle part below the copper lock nut, on the wall of recess, make pin-and-hole 10, on the outward edge of recess, make locking cap opening 11, pellet shot from a slingshot hole on the quantity of locking cap opening and the plastics valve body is complementary, on the copper lock nut center portion make polygon in recess, polygon outer lug boss is made at one side middle part on the shank of the key, the limit number of recess is identical in polygon on its limit number and the copper lock nut, the edge of polygon outer lug boss one side makes the magnetic marble hole on the shank of the key, its quantity is identical with locking cap opening quantity on the copper lock nut, and the position is corresponding; The copper valve rod is installed in the plastics valve body, employing is given and is buried technology, spring is placed in the pellet shot from a slingshot hole on the plastics valve body, magnetic marble put be contained on the spring, the copper lock nut is fitted in the interior recess on the plastics valve body, steel pin is installed in the pin-and-hole on copper valve rod and the copper lock nut, copper valve rod, copper lock nut are installed together, last magnetic marble is installed in the magnetic marble hole on the shank of the key, at this moment, the lower end of last magnetic marble is identical with the magnetic pole of magnetic marble upper end, and spanner is installed on the shank of the key, and the shank of the key is placed on the copper pin cap.
