Abstract
The utility model discloses a magnetic valve which comprises a valve body on which an inlet end and an outlet end are arranged, a valve core used for connecting or disconnecting the inlet end and the outlet end, and a valve handle controlling the valve core. The utility model is characterized in that at least one part of the valve handle is arranged in an isolated cap; inner magnetic steel is installed on the part of the valve handle arranged in the isolated cap; outer magnetic steel corresponding to the inner magnetic steel is installed outside the isolated cap in a rotary mode; a handgrip which can make the outer magnetic steel rotate is installed on the outer magnetic steel. The utility model is a leak-free valve gate and is especially suitable for being used for conveying flammable, explosive and toxic fluid.
Description
The utility model relates to a kind of valve, particularly relates to a kind of valve that adopts the magnetic force coupling.
Existing valve is because valve rod is a moving element.Sealing between valve rod and valve body is owing to the motion of valve rod becomes unreliable, and therefore, fluid often leaks between valve rod and valve body.
The purpose of this utility model provides a kind of non-leakage magnetic valve that utilizes the transmission principle of magnetic force shaft joint and design.
The purpose of this utility model realizes by following design proposal, and a kind of magnetic valve comprises a valve body, has an entrance point and an outlet end on valve body; One is used to that entrance point and outlet end are communicated with or the spool of disconnection; The valve rod of control spool; It is characterized in that, at least a portion of said valve rod is arranged in the isolating cap, an interior magnet steel is installed on the valve stem part in placing isolating cap, the outside and interior magnet steel at isolating cap are rotatably mounted an outer steel accordingly, and the handle that can make its rotation is installed on outer steel.
The utility model by rotate outer steel drive in magnet steel rotate, realize moving up and down or rotating of spool thus and reach and open or the purpose of cut-off valve.
Because valve rod of the present utility model is in the housing of a sealing, therefore the motion of valve rod can not cause leakage, as long as the sealing in the utility model between said isolating cap and the valve body can be guaranteed (this is easy to realize for those of ordinary skills), the utility model can become a kind of leak free valve fully.Inflammable, explosive and poisonous FLUID TRANSPORTATION that the utility model is particularly suitable for.
Below in conjunction with accompanying drawing the utility model is explained in more detail.
Fig. 1 is the cross-sectional schematic of magnetic valve of the present utility model.
Referring to Fig. 1, this figure is a principle sketch of the present utility model.This magnetic valve comprises a valve body 8 and a valve outlet 9.Spool 2 places import 8 and exports between 9, is used to open or cut off import 8 and exports passage between 9.Fixed installation one valve rod 3 on valve body 2, spool 2 is driven by valve rod 3 and moves, its motion mode can be to move up and down, and also can be to drive spool 2 by valve rod 3 to rotate (not shown this structural type, this structure are conspicuous for those of ordinary skills).An isolating cap 5 is installed in sealing on valve body 1, and the part of valve rod 3 (at least a portion in other words) places in the isolating cap 5.Magnet steel 7 is installed on the interior magnet steel carrier 10 with internal thread in one, is having the outside thread that matches with internal thread on the carrier 10 on the valve rod 3.In the outside of isolating cap 5, with interior magnet steel 7 outer steel 6 is installed accordingly, outer steel 6 can rotate around isolating cap 5, and internal-external magnetic steel 6,7 is in the same plane, and handle 4 is installed on outer steel 7.
When handle with sleeve 4 makes outer steel 6 when isolating cap 5 rotates, because magnet steel 7 attracts (or repulsion) effect in 6 pairs of the outer steels, magnet steel 7 rotates with outer steel 6 in making.Because interior magnet steel is fixed on the carrier 10, on carrier 10, have internal thread, this internal thread matches with outside thread on valve rod 3, so valve rod 3 or move up or down is realized the unlatching of valve thus or closed.Obviously, magnet steel is fixedlyed connected with valve rod in also can making, and valve rod is rotated and realizes the unlatching of valve or closes that at this moment, spool is a kind of rotational valve core, not shown this structure.
It is pointed out that at this Fig. 1 only is a kind of schematic representation, its purpose only is to point out a kind of design, can make multiple modification in this design scope.For example, interior magnet steel carrier 10 usefulness keys or other Placements are fixed on the valve rod 3, valve rod 3 and spool are for being rotatably connected, an annular boss that has internal thread is set in isolating cap 5, outside thread on the valve rod 3 matches with internal thread on the boss, drives valve rod and rotate when interior magnet steel rotates with outer steel, because the internal thread of annular boss and the externally threaded cooperation on the valve rod 3, valve rod 3 is moved up and down, thereby open or throttle down.And for example, in order to reduce the surface friction drag between outer steel and the isolating cap, can between outer steel and isolating cap, bearing be installed.
Claims (5)
1, a kind of magnetic valve comprises a valve body, has an entrance point and an outlet end on valve body; One is used to that entrance point and outlet end are communicated with or the spool of disconnection; The valve rod of control spool; It is characterized in that, at least a portion of said valve rod is arranged in the isolating cap, an interior magnet steel is installed on the valve stem part in placing isolating cap, the outside and interior magnet steel at isolating cap are rotatably mounted an outer steel accordingly, and the handle that can make its rotation is installed on outer steel.
According to the said magnetic valve of claim 1, it is characterized in that 2, said spool is a kind of spool of vertical motion up and down.
3, magnetic valve according to claim 2 is characterized in that, said in magnet steel be installed in one and have on the interior magnet steel carrier of internal thread, having the outside thread that matches with internal thread on the interior magnet steel carrier on the valve rod.
4, magnetic valve according to claim 2 is characterized in that, said in magnet steel be fixed on the valve rod, in said isolating cap, have an annular boss that has internal thread, having the outside thread that matches with internal thread on the annular boss on the said valve rod.
According to the magnetic valve of claim described 1, it is characterized in that 5, said spool is a kind of rotational valve core.
