Abstract
The utility model discloses a magnetic interlock valve which does not need filler to seal, which comprises a valve body, a valve block, a valve stem component, an inner rotor, an outer rotor, a yarn trumpet and a deceleration motor. The utility model is characterized in that the inner rotor and the outer rotor are separated through a yarn trumpet, and the rotation of the inner rotor is anchored by magnetic field of a high-strength permanent magnet on the outer rotor which transmits the yarn trumpet. Compared with the prior valve which adopts the filler or a sealing ring for sealing, the utility model thoroughly eliminates the hidden danger of water leakage from the root of a valve stem due to frequent opening and closing. Compared with existing magnetic valves, the utility model solves the failure potential due to bad water quality thoroughly, and has the function of keeping the valve position, which can be widely applied in the computer management and control system of manual thermoregulation heating and automatic household and room heating according to needs.
Description
Technical field
The utility model relates to a kind of magnetic force interlocking valve without filler and seal ring sealing, belongs to a kind of magnetic field of permanent magnetism that utilizes and sees through the valve that the stainless steel separator drives the control of rotating ferromagnetic class material rotor realization switch.
Background technique
Inventive concept without the magnetic force interlocking valve of filler and seal ring sealing comes from the system development of patent of invention " computer management of household heating and control system ".Because this project implementation must be used shutoff formula electric valve and the electronic change-over valve of Three way type with long-range controlled function.Especially, the electronic change-over valve of the Three way type that will use, the amount that relates to is big, wide, and all is dispersed in every family, and each valve all may need frequent switch.Therefore, possessing under the prerequisite of remote-controllable, also must possess durability, rugged environment adaptability has remarkable economy simultaneously in energy-conservation process, and frequent switch does not have the characteristics of the hidden danger of leaking down.And existing valve, no matter be remote controlled solenoid valve, locking valve that still can be transformed into telecontrol etc. all can't satisfy these requirements.For example: application number is 03119132.0 patent of invention " the antitheft locking valve that low temperature is opened automatically ", though under up-to-standard prerequisite, be a kind of technology of the trouble and worry of not leaking, and also locks and Keys can be made into the electronic problem that solves telecontrol.But its internal structure very easily is subjected to the influence of water quality inferiority and is malfunctioning.Just also has on a kind of market solenoid valve, the shortcoming of except having above problem, exist also that operating current is big, outage can not two-way maintenance in popular telecontrol; Also having a kind of is the valve that is going on the market, and controls electronic locking valve with the ball valve transformation of the way with the locking valve of key operation or with magnetic card, though can solve the problem of telecontrol, it can not be eliminated and leak and malfunctioning trouble and worry.
Summary of the invention
Goal of the invention of the present utility model is, for " computer management of household heating and control system " provide a kind of can telecontrol, the hidden danger of not leaking, stable and reliable for performance, working service is simple and the life-span is long electronic change-over valve.
Technical solution of the present utility model is achieved in that
A kind of magnetic force interlocking valve without filler and seal ring sealing, comprise reducing motor and valve body, it is characterized in that: also comprise external rotor system that is made of outer rotor shaft and permanent magnet I and the internal rotor system that is made of permanent magnet II and inner rotor shaft, wherein said outer rotor shaft is the prolongation of reducing motor axle; Inner rotor shaft then is threaded with wherein valve rod assembly by the mesopore of valve body, and there is valve block the lower end of valve rod assembly, and valve block is because of the screw thread transmission lifting of valve rod assembly, thereby realizes the open and close of valve; Between described inside and outside rotor shaft, separator also is housed, its upper and lower end face freely is connected with the axle head of rotor shaft respectively; The outside of separator suit attaching nut, the screw thread on attaching nut and the valve body screws, and the reducing motor that will have electric machine support is fixed on the valve body.Resistance also is housed in the valve pocket of described valve body ships and resell on another market, be used to stop the rotation of valve rod assembly.
Compared with prior art, the advantage of the magnetic force interlocking valve of the present invention's proposition shows:
1, compares with the various valves that adopt the sealing of filler and seal ring, thoroughly eliminated the hidden danger of leaking from the valve rod root because of frequent switch.Have laid a good foundation for long-range electronic control simultaneously.
2, compare with the solenoid valve that does not adopt the sealing of filler and seal ring, thoroughly eliminated because of the malfunctioning hidden danger of water quality inferiority.The outage that has solved telecontrol simultaneously keeps the valve position problem.
Description of drawings
Fig. 1 is the axial section structural representation without the gland sealed magnetic force interlocking valve of the present invention.
Among the figure, 1 reducing motor, 2 outer rotor shafts, 3 electric machine supports, 4 permanent magnet I, 5 attaching nuts, 6 separators, 7 permanent magnet II, 8 inner rotor shafts, 9 valve rod assemblies, 11 valve blocks, 12 valve bodies are shipped and resell on another market in 10 resistances.
Embodiment
As shown in Figure 1 a kind of without the gland sealed magnetic force interlocking valve, utilize the magnetic field of permanent magnet can see through metal such as stainless steel, copper, plastics and non-metallic objectsit is not a metal object attracts soft iron, low carbon steel, carbon steel, silicon steel, the characteristics that comprise objects such as permanent magnet, driving the external rotor of being made up of high strength permanent magnets with a minitype speed reducing motor rotates, allow magnetic field see through the stainless steel separator and drive rotating internal rotor, and drive valve rod and valve plate movement by the screw thread transmission that inner rotor shaft and valve rod constitute, to realize changing or turn-offing the function of flow path.
Forming functional part of the present invention has:
A valve body is used for other functional part of biased valve, and with being connected of pipeline;
A valve block, the path that is used to change or turn-off current;
A valve rod assembly is used to drive valve plate movement, changes the position of valve block;
An internal rotor and the axle that is fixed together are used under the effect of magnetic field gravitation, rotate with magnetic field, and the front end of axle has screw thread, drives valve rod and valve plate movement simultaneously;
A stainless steel separator that is contained in the middle of the inside and outside rotor shaft is used for sealing, leakproof, allows magnetic field, top see through the stainless steel separator simultaneously and attracts internal rotor;
An external rotor is used for arranging and fixed permanent magnet;
The support of minitype speed reducing motor and fixed electrical machinery, it also is the external rotor guard shield, the axle of its motor is connected with external rotor, be used to drive external rotor, so that allow the magnetic field suction internal rotor of high strength permanent magnets rotate, thereby turn-off or change the path of current in the pipeline by the motion control that drives valve rod and valve block.
