Description
Technical field
The utility model relates to a kind of electromagnetic valve body, is specifically related to the electromagnetic valve body that a kind of plastics are made.
Background technique
See Fig. 1, be used at present metallic conduit to the liquid road by and the solenoid valve controlled of conducting, its structure mainly comprises coil block 2A, membrane module 3A, plastics or metal valve body 1A and is connected metal fill hose joint 4A and titting water outlet 5A on the valve body.This kind solenoid valve serial connection is used in metallic conduit, because fill hose joint 4A and titting water outlet 5A adopt with metallic conduit and are threaded, so the fill hose joint 4A and the titting water outlet 5A that are connected with its valve body also will make with metallic material, because if fill hose joint 4A and titting water outlet 5A are made of plastic, then because the easy stripped thread of plastic whorl and its expansion coefficient and metallic material differ very big, will have a strong impact on the working life of this kind solenoid valve, even make the pipeline leakage.
See Fig. 2, the plastics valve body upper valve body 1A of such solenoid valve is provided with intake chamber 11A, the 12A of water-supplying chamber, closed chamber 13A, intake pipe interface 14A, coil block interface 15A and outlet pipe interface 16A; Intake pipe interface 14A is positioned at the left end of valve body 1A; Coil block interface 15A is positioned at the upper end of plastics valve body 1A; Outlet pipe interface 16A is positioned at the right-hand member of valve body 1A; The intake chamber 11A of valve body 1A has water intake 111A and water outlet 112A, and water intake 111A is positioned at the central authorities of intake pipe interface 14A; The closed chamber 13A of valve body 1A has lower end mouth 131A and upper end-hole 132A, and upper end-hole 132A is positioned at the central authorities of coil block interface 15A; The 12A of water-supplying chamber of valve body 1A is provided with water intake 121A and water outlet 122A, and water outlet 122A is positioned at the central authorities of outlet pipe interface 16A, and water intake 121A also is the lower end mouth 131A of closed chamber 13A; Described intake chamber 11A is communicated with the 12A of water-supplying chamber by the water intake 121A of its water outlet 112A and the 12A of water-supplying chamber; If described coil block 2A comprises a plastic closure 21A who has a blind hole 211A, one and is used for spring 23A and the iron core 24A that the field coil 22A in magnetic field is provided and is located at described plastic closure blind hole 211A from the top down successively that described iron core 24A also is provided with rubber stopper 25A at the end near described membrane module 3A; Its membrane module 3A comprises elastic sealing film 31A and pressure release part 32A, have relief hole 321A on the pressure release part 32A, when the plastic closure 21A among the coil block 2A is pressed on the edge of the elastic sealing film 31A in the described closed chamber, described membrane module 3A just and the space that surrounds of described plastic closure 21A formed a pressure chamber.This kind solenoid valve just the switching by control relief hole 321A the elastic sealing film 31A of the core of elastic sealing film 31A is moved down or on move, thereby the water intake 121A of the 12A of water-supplying chamber is sealed or opens, also promptly realize solenoid valve ending and conducting pipeline.Concrete working procedure is: when solenoid valve cuts off the power supply, described iron core 24A drives rubber stopper 25A and is displaced downwardly to the relief hole 321A that clogs among the described pressure release part 32A under the restoring force effect of spring, promptly close this relief hole 321A, make the elastic sealing film 31A of the core of described elastic sealing film 31A seal up the water intake of described valve body water-supplying chamber, make the water outlet 112A of described intake chamber 11A and the water intake 121A of the 12A of water-supplying chamber no longer communicate, thereby make the liquid road interrupt; When solenoid valve is switched on, described iron core 24A is subjected to the attraction of field coil and drives rubber stopper 25A upwards to remove from relief hole 321A, no longer block the water intake of described valve body water-supplying chamber, promptly open this relief hole 321A, thereby make described intake chamber 11A communicate with the 12A of water-supplying chamber by the water intake 121A of its water outlet 112A and the 12A of water-supplying chamber; Even also the liquid road is unimpeded.
Because the water intake and the relief hole aperture of this type of electromagnetic valve body water-supplying chamber are smaller, especially the aperture of relief hole is generally less than 1mm, is very easily stopped up by the foreign material in the water; Simultaneously since described iron core also very easily because of the foreign material in the water are stuck in the blind hole, thereby cause whole solenoid valve malfunctioning.For preventing the generation of this type of fault, present solenoid valve all with metal fill hose joint that plastics valve body feed-water end is connected in the smaller filter screen in an aperture is set with the ducted foreign material of elimination.
Chinese patent literature CN2636030Y discloses a kind of electric control valve joint of being connected with intake pipe interface on the electromagnetic valve body of being used for, it also is the metal fill hose joint that is connected with plastics valve body feed-water end recited above, the main body of this kind electric control valve joint is a T shape Three way type pipe joint, in its vertical pore chamber, a filter screen is set, and being provided with the blanking cover that is threaded with this sector hole chamber in the port that this section is provided with the pore chamber of filter screen, the effect of this blanking cover is that this section of sealing is provided with the pore chamber of filter screen and filter screen is fixed in the described pore chamber.
In actual production, this kind electric control valve joint need use the higher metallic material of price for example copper material make the electric control valve adapter body, nickel plating outside the electric control valve adapter body then, be fixed in screw at last and form a complete solenoid valve on the water inlet interface of electrically-controlled valve main body and sell away, but now use lower plastics of price such as polypropylene or ABS resin to make as coupled electrically-controlled valve main body more, so this kind electric control valve joint has accounted for than great share in the cost of this solenoid valve, the cost that has caused using the solenoid valve that this kind electric control valve joint makes is not according to height not down.
