Problems solved by technology

But its internal structure is highly susceptible to failure due to poor water quality
There is also a remote control solenoid valve that is popular in the market. In addition to the above problems, it also has the disadvantages of large operating current and cannot be maintained in both directions when power is off. Switching the lock valve, or using a magnetic card to control the electric lock valve can solve the problem of remote control, but it cannot eliminate the worries of water leakage and failure

Embodiment 1

[0025] See attached Figure 1.

[0026] The permanent magnet positioning rings 18 and 20, the permanent magnet 19, and the outer rotor shell 21 are assembled into an outer rotor. The inner rotor 14 and the threaded inner rotor shaft 13 are fastened together by a static fit. Fix the geared motor 24 and the outer rotor guard 22 with the motor fixing screw 23 together. The valve plate 6 is sent into the valve cavity through the water inlet of the valve body 1, and the valve plate 6 and the valve stem 10 are fixed as a whole with the screw 5. Then, the valve stem brackets 7, 8, 9 and the valve stem bracket positioning top pipe 11 and the inner rotor shaft positioning frame 12 are placed in the cavity shown in the figure in sequence. Insert the inner rotor 14 and the threaded inner rotor shaft 13 that are fixed together in advance into the hole of the inner rotor shaft positioning bracket 12, and screw a part of the thread into the screw hole of the valve stem 10. Insert the gasket ...

Abstract

The invention discloses a magnetic linkage valve which is not sealed by a filling material or a sealing ring. The invention consists of a valve body, a valve plate, a valve rod component, an internal rotor, an external rotor, an isolation cover, a decelerating motor and / or a manual part. The invention is characterized in that the internal rotor and the external rotor are isolated by the isolationcover; the rotation of the external rotor is driven by the decelerating motor and / or the manual part; the rotation of the internal rotor is driven by the magnetic field of a high-intensity permanent magnet on the external rotor by reaching through the isolation cover. Compared with the existing valve which is sealed by the filling material or the sealing ring, the invention thoroughly eliminates the hidden trouble of water leakage at the root of the valve rod owning to frequent switching; compared with the existing electromagnetic valve, the invention thoroughly eliminates the hidden trouble of malfunction owning to poor water quality, meanwhile, the invention has the function of keeping the valve level without electricity. Therefore, the invention can be widely applied to the fields suchas heat supply, chemical industry, etc.

Description

Technical field [0001] The invention relates to a magnetic linkage valve without packing and sealing ring sealing, and belongs to a valve which uses a permanent magnet magnetic field to drive a rotatable ferromagnetic material rotor through a stainless steel outer cover to realize switch control. Background technique [0002] The inventive concept of a magnetically linked valve that does not require packing and sealing rings is derived from the system development of the invention patent "Computer Management and Control System for Heating on Demand by Households and Rooms". Due to the implementation of this project, shut-off electric valves and three-way electric reversing valves with remote controlled functions must be used. In particular, the three-way electric reversing valve to be used involves a large amount and a wide range, and is scattered in various households, and each valve may need to be opened and closed frequently. Therefore, under the premise of remote control, it ...
