Embodiment
As shown in Figure 1, magnetic core pipe assembly of the present invention includes nose end lid 4, magnetic core barrier part 7 and atresia end cap 9, the porose end cap 4 of a termination of magnetic core barrier part 7, another termination atresia end cap 9 of magnetic core barrier part 7; Step-like armature lifter 3 is housed in the magnetic core pipe assembly, and after the small end of armature lifter 3 passed porose end cap 4, the small end of armature lifter 3 was exposed at outside the magnetic core pipe assembly; Coil block comprises solenoid housing 6 and coil 12, be contained in outside the magnetic core pipe assembly, end cap nut 8 is threaded with atresia end cap 9, be pressed on the side of solenoid housing 6, solenoid housing 6 is equipped with first sealing ring 2 near on the side of porose end cap 4, solenoid housing 6 is equipped with second sealing ring 10 near in the endoporus of atresia end cap 9, and porose end cap 4 is exposed at solenoid housing 6 outer sides the 3rd sealing ring 5 is housed; Described solenoid housing 6 is titanium alloy or Stainless Steel Shell.
Described solenoid housing 6 also is equipped with the 4th sealing ring 1 near the side of porose end cap 4, and described solenoid housing 6 also is equipped with the 5th sealing ring 11 near in the endoporus of atresia end cap 9.
The basic functional principle of sea water hydraulic electromagnet is: coil 12 energising backs produce magnetic field, its magnetic line of force constitutes magnetic circuit through magnetic core pipe assembly, armature lifter 3, spatial joint clearance etc., armature lifter 3 is produced suction, and this suction outputs to the outside by armature lifter 3.Because the coil 12 of coil block inside can not bear high pressure; so first sealing ring 2 and second sealing ring 10 have been installed at the two ends of solenoid housing 6; operating position for superhigh pressure; as abyssal environment; should consider double sealing; promptly increase the 4th sealing ring 1 and the 5th sealing ring 11, shown in Fig. 1 is exactly the double sealing structure.The 3rd sealing ring 5 is used for the connection sealing with hydraulic valve.Because material, general electromagnet does not have corrosion resistant characteristic, and the present invention adopts titanium alloy or stainless steel as shell, so have excellent corrosion resisting performance, can use sea (light) water to be medium, and can directly soak in water.Electromagnet is divided into two kinds of wet type and dry types, and high pressure all can not bear in the inside and outside portion of common air-gap solenoid, and high pressure can be born in common wet electro-magnet magnetic core pipe inside, but high pressure can not be born in the outside, and coil is not taked high pressure sealing yet.Structure of the present invention is after Intensity Design, and high pressure can both bear in inside and outside portion, reaches high pressure resistant requirement.
One embodiment of the present of invention as shown in Figure 2, the combination of sea water hydraulic electromagnet and unidirectional valve forms a sea water hydraulic electric control one-way valve.Porose end cap 4 exposes the end and is connected with unidirectional valve valve body 13, and connected mode can be to be threaded, and also can be that flange connects.In like manner, with sea water hydraulic electromagnet and the combination of other change valves, can draw various sea water hydraulic solenoid directional control valves.
Above-mentioned embodiment is used for the present invention that explains, rather than limits the invention, and in the protection range of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
