Abstract
The utility model relates to an electromagnetic control valve for fluid. Rubber films in the prior art have the defects of loose tightness, easy corrosion and easy aging. A coil, an iron core and a barrel type cavity are respectively arranged inside a valve body and a cover cap, and a sluice gate is arranged on the wall of the cavity which is sealed by a piston and a piston ring; the piston ring comprises two gas rings and two oil rings, and the iron core and the piston are connected into a whole to support a spring. When power is cut off, the piston blocks the sluice gate; when the power is supplied, the coil attracts the iron core, and the piston opens the sluice gate. The piston ring, the piston and a working barrel wall are respectively made of manganese alloy, aluminum alloy and copper alloy which are respectively plated with chromium. The utility model has the advantages of corrosion and aging resistance, impact resistance, high-temperature and high-voltage resistance, long service life, high sensitivity and good tightness.
Description
The utility model relates to the solenoid electric valve of a kind of control valve for fluids, particularly fluid.
The solenoid electric valve of existing fluid, the valve body top that is provided with access way is furnished with cover cap, the coil that connects power line is housed in valve body and the cover cap and can be energized coil and inhale moving iron core,, but have one to pass in and out the rubber membrane of sluice gate for the shutoff fluid of one with the iron core dress at the sealing part of importing and exporting passage.The problem that exists is a caulking gum shutoff bad sealing, and burn into is aging easily, causes solenoid valve to leak, and not wear-resisting, the life-span is short, can not high temperature high voltage resistant or corrosive fluid.
The utility model is at the deficiencies in the prior art, proposed the solenoid electric valve of the fluid of the long high sealing degree of corrosion-resistant aging, the high temperature high voltage resistant of a kind of usefulness, life-span.
Task of the present utility model is to realize like this, the solenoid electric valve of fluid of the present utility model, the valve body that is provided with access way is furnished with cover cap, the coil that connects power line is housed in valve body and the cover cap and can be energized coil and inhale moving iron core, be provided with the cartridge type cavity in the valve body, fluid turnover sluice gate is located on the wall of cartridge type cavity, be provided with the piston and the piston ring of sealing in the cartridge type cavity, piston ring is twice compression ring and twice oil ring, and iron core one end and piston connect as one, and the other end heads on spring.During the piston valve outage, under the effect of core ends spring, piston is with the sealing of the turnover of the fluid on cartridge type cavity wall sluice gate; During energising, coil produces magnetic field, inhales moving iron core, and drive piston and piston ring leave the fluid turnover sluice gate on the cartridge type cavity wall, and fluid is unimpeded at sluice gate.
Described solenoid electric valve, piston ring, piston and work barrel are caused by manganese alloy, aluminum alloy and the Cuprum alloy of chromium plating respectively.
The utility model has compared with prior art been taked piston and piston ring packing, corrosion-resistant aging, shock-resistant, high temperature high voltage resistant, long service life, and highly sensitive, good airproof performance does not leak.
Fig. 1 is a sectional structure schematic representation of the present utility model.
Fig. 2 be prior art the sectional structure schematic representation.
Among Fig. 2, valve body 31 tops that are provided with access way are furnished with cover cap 36, the coil 34 that connects power line 35 is housed in valve body 31 and the cover cap 36 and can be energized coil 34 and inhale moving iron core 32, at the sealing part of importing and exporting passage, but there is one to be the rubber membrane 33 of the shutoff fluid turnover sluice gate of one with iron core 32 dresses.
Fig. 1 is an embodiment of the present utility model.The valve body 1 that is provided with access way is furnished with cover cap 7, the coil 6 that connects power line 9 is housed in valve body 1 and the cover cap 7 and can be energized coil 6 and inhale moving iron core 4, be provided with the cartridge type cavity in the valve body 1, fluid turnover sluice gate is located on the wall of cartridge type cavity, be provided with the piston 3 and the piston ring 2 of sealing in the cartridge type cavity, piston ring 2 is twice compression ring and twice oil ring, and iron core 4 one ends and piston 3 connect as one, and the other end heads on spring 5,8.During the piston valve outage, under the effect of iron core 4 end springs 5,8, piston 3 is with the sealing of the turnover of the fluid on cartridge type cavity wall sluice gate; During energising, coil 6 produces magnetic field, inhales moving iron core 4, and drive piston 3 and piston ring 2 leave the fluid turnover sluice gate on the cartridge type cavity wall, and fluid is unimpeded at sluice gate.Piston ring 2, piston 3 and work barrel are caused by manganese alloy, aluminum alloy and the Cuprum alloy of chromium plating respectively.
