Abstract
The utility model discloses a magnetic transmission pilot valve. The magnetic transmission pilot valve comprises a valve body and a valve core, wherein an inlet and an outlet are formed in the valve body. The valve core comprises a valve rod provided with a blind hole structure, a magnet ring and a limiting device of the magnet ring are arranged on the outer wall of the valve rod in a sliding mode, a handle is fixedly arranged on the lower portion of the magnet ring, and a pressure spring and a guide pillar are arranged in a blind hole from bottom to top, wherein a magnetic sheet is fixed at the lower end of the guide pillar. The top end of the valve rod is of a disk structure which is opened upward, a disk plug with an elastic sealing gasket is movably buckled in the upward-opened disk, and the middle portion of the disk plug is of an upward-protruding hollow cylinder structure. A drainage hole which penetrates through the elastic sealing gasket and is communicated with the inlet is formed in the disk surface of the disk plug. The magnetic transmission pilot valve has the advantages that the structure is simple, sealing effects are good, the valve can be opened and closed without electric drive and mechanical transmission, the size and failure rates of the fluid valve are reduced, the service life of the valve is prolonged, meanwhile, electric energy is saved, and manual work is saved.
Description
Technical field
The utility model relates to Fluid valve, especially relates to a kind of magnetic transmission pilot valve.
Background technique
Existing valve, adopt the mode that changes the pipeline area of passage to realize the switch control of convection cell mostly, and the operation that changes valve body and the long-pending relative position of controlled pipeline overflow section is finished by mechanical motion or electric drive, owing to there is mechanical transmission, so the complex structure volume is big and rate of fault is higher, and because the elevating movement of valve rod makes Sealing very easily wear and tear, be easy to generate seepage, shortened the working life of valve greatly.And the total axial force of valve rod when closing comprise from the sealing load on the valve seat, acts on medium power on the flap etc., causes total axial force of valve rod very big, the material of valve rod required very high, damages easily.
Summary of the invention
The utility model purpose is to provide a kind of simple in structure, good sealing effect, improved working life and unregulated power drives or mechanically operated magnetic transmission pilot valve.
For achieving the above object, the utility model can be taked following technical proposals:
Magnetic transmission pilot valve described in the utility model, comprise the valve body, the spool that have import and outlet, described spool comprises the valve rod that is provided with blind hole structure, described valve rod outer wall slides and is provided with magnet ring and limit stoper thereof, described magnet ring bottom is installed with handle, is provided with the guide pillar that fixedly there is magnetic sheet pressure spring and bottom in described blind hole from bottom to top; The top of valve rod is the upper shed disc structure, and movable the fastening has the dish of band elastic sealing gasket stifled in described upper shed disk, and the stifled middle part of described dish is the hollow cylinder body structure that raises up; The card stifled at dish offers the conduction hole that runs through elastic sealing gasket and communicate with import.
In described upper shed disk and the stifled chamber that surrounds of the dish of band elastic sealing gasket, be positioned at described conduction hole lower position and be provided with a spring, the spring silk of described silk spring extends upwardly in the conduction hole.
Described valve rod is connected on the valve body by land, and described limit stoper comprises the upper shed connecting plate that is fixed on the described land, and described upper shed connecting plate bottom offers through hole, and described handle runs through described through hole and extends to upper shed connecting plate bottom.
The utility model advantage is simple in structure, and good sealing effect realizes that the keying of valve neither needs electric drive not need mechanical transmission again, reduce structure and volume and the rate of fault of fluid valve, improved its working life, saved electric energy again simultaneously, saved artificial.
