A) in valve body one end outside the cylindrical platform that withstands outer spring is arranged, the other end is equipped with the pipe collar that connects valve body and outlet pipe, by valve body outside thread and pipe collar screw-internal thread fit, at valve interior wall taper platform that joins with O shape circle and the interior round platform that withstands inner spring are arranged, the long strip supporting rib is arranged on the valve interior wall of spool sliding area correspondence, close-fitting cylindrical shape outer magnetic ring is housed on the valve shell corresponding with internal magnetic ring, and the outer magnetic ring front end withstands outer spring, and rear end and handwheel join;

B) spool is made up of hollow cylindrical internal magnetic ring and hollow valve head, internal magnetic ring is installed on the valve head shell, front end and valve head circle platform join, rear end and O shape circle join, the valve head front end is the streamline dome, the rounded end socket of tail end, the round platform that withstands inner spring is arranged at the circular head bottom, and a half slot that cooperates with O shape circle is arranged near the circle platform;

C) handwheel by screw-thread fit is arranged on valve shell, internal thread cooperates with outside thread on the shell in the middle of the handwheel, and the handwheel outer fringe surface has annular knurl or protruding pattern.

Owing to take technique scheme, make the utility model compared with the prior art have following advantage and effect:

A) valve of the present utility model externally adopts full-closed structure, avoided the external leakage phenomenon to take place, internally adopt unidirectional taper valve core to utilize hydraulic pressure to realize sealing, pressure reduction is big more, sealing is good more, therefore also having avoided the internal leakage phenomenon to take place, is a kind of leakage-free valve that fundamentally solves the inside and outside leakage phenomenon of valve.

B) control section is realized switch by the suction that the interior outer magnetic ring of making of magnetic material produces, and is therefore simple in structure, easy to make.

C) easy to operate, safe and reliable, the life-span is long,

D) magnetization water quality is beneficial to water and purifies.

Description of drawings:

Fig. 1 is the utility model structural representation

Below in conjunction with drawings and Examples the utility model is further described:

The utility model adopts external totally-enclosed valve body structure, control section is made one at outer magnetic ring on the valve shell and the internal magnetic ring on the spool with the magnetic material neodymium iron boron, utilize magnetic attraction between the two, by handwheel on the rotary valve shell, the driving outer magnetic ring moves, make internal magnetic ring with moved further and drive spool and move, realize opening and closing.

Valve body among the figure (1) two ends internal thread cooperates with the outside thread of turnover water pipe respectively, valve body one end outer circle platform (10) withstands and the close-fitting outer spring of valve shell (2), the outer spring the other end and outer magnetic ring hold out against, outer spring is enclosed within on the valve shell, can make valve switch steady, utilize the pressure of spring to make valve core reset when throttle down, the while is the size of the may command adjustment water yield also; The valve body the other end is equipped with the pipe collar (9) that is used to connect valve body and outlet pipe, the taper platform (15) that joins with O shape circle (7) is arranged at valve interior wall, the valve closing state * both closely cooperate, both throw off when valve opening, withstand the interior round platform (17) of inner spring (8) in the valve body in addition, inner spring can be offset the excessive water pressure of a part, neodymium iron boron outer magnetic ring volume is reduced, thereby reduce cost; The long strip supporting rib is arranged on the valve interior wall of spool sliding area correspondence, and supporting rib has at least more than four, and supporting rib when spool is subjected to water turbulence, does not produce beat in the valve interior wall substantially horizontal; Close-fitting cylindrical shape outer magnetic ring (4) is housed on the valve shell corresponding with the internal magnetic ring of spool outside, and the outer magnetic ring front end withstands outer spring, and rear end and handwheel join; Valve body is made by nonmagnetic substance, as the copper aluminium of metallic material; The bakelite of nonmetallic material, plastics, spool is made up of hollow cylindrical internal magnetic ring (5) and hollow valve head (3), internal magnetic ring snugly fits on the valve head shell, front end and valve head circle platform (13) join, rear end and O shape circle join, the valve head front end is streamline dome (12), the rounded end socket of tail end (18), when current out-of-date, resistance is very little, does not produce eddy current, and the round platform (16) that withstands inner spring is arranged at the circular head bottom, the half slot (14) that cooperates with O shape circle is arranged near the circle platform, O shape circle being installed in the half slot tightly prevents to become flexible, and whole valve head is hollow, make by plastic materials or rubber, therefore, the weight of spool is also very little, and activity freely in valve body; The spool wear and shock-resistant improves sealability simultaneously.Outside thread and handwheel (6) circular hole screw-internal thread fit is arranged on valve shell, and outer fringe surface has annular knurl or protruding pattern, is convenient to operation.

The utility model valve opening and close situation: pull handwheel (6) with hand, the outer magnetic ring (4) that drive is made by the magnetic material neodymium iron boron moves to the water inlet direction, because magnetic force, the internal magnetic ring of being made by the magnetic material neodymium iron boron (5) is also moved to the water inlet direction, thereby drive spool to the same moved further of water outlet direction, the O shape circle (7) that is enclosed within the spool half slot (14) breaks away from valve body (1) inwall taper platform (15) and the generation gap, under the pressure effect of water, enter outlet pipe by the gap, valve opening finishes, and by adjusting the progress of handwheel, promptly adjusts the distance size of spool and taper platform, the adjustment and the control of flow have been finished, when pulling handwheel in the other direction, spool contacts with the taper platform, and O shape circle joins with the taper platform, valve is closed condition, as shown in Figure 1: the valve closing state.Under strong magnetic force, close tightly, let out in having prevented, obstructed because whole valve pocket is a full-closed structure with the external world, do not leak so do not produce, so the utility model valve problem that leaks in fundamentally avoiding.

Because internal magnetic ring on the spool and the outer magnetic ring on the valve body are made by magnetic material, when water flows through valve, water quality are magnetized, thereby have purified water quality.

When valve parts damages, earlier valve is taken off from turnover water pipe, unload handwheel again, claw outer magnetic ring with hand and change, take out spool, take off down internal magnetic ring, more renew internal magnetic ring, therefore easy to operate.
