Abstract
The utility model discloses a direct action type self-correction two-way solenoid valve which overcomes the defect that the sealing property is lowered as the axis of a moving iron core is apt to deviate from the plane of a valve port in the existing similar products. The direct action type self-correction two-way solenoid valve comprises a valve body (5), a solenoid (1) and a moving iron core (3), wherein two ends of the valve body (5) are respectively provided with an inlet (9) and an outlet (10) and the cavity of the valve body (5) is provided with a valve port (11); the cavity of the solenoid (1) is provided with a duct (2) supporting the moving iron core (3) to slide; and the outer edge of the lower port of the moving iron core (3) is provided with a pagoda spring (7). The direct action type self-correction two-way solenoid valve is characterized in that the lower end of the moving iron core (3) is provided with a step-like cylindrical cavity (13), a rubber sealing cushion (8) is arranged in the step-like cylindrical cavity (13), and a correction spring (12) is arranged between the rubber sealing cushion (8) and the bottom surface of the cylindrical cavity (13). Compared with the existing product, the direct action type self-correction two-way solenoid valve has the advantages of being ingenious in concept, simple in structure, convenient and practical.
Description
Technical field
The utility model relates to a kind of solenoid valve product manufacturing technology, especially refers to the automatic deviation correction structure technology between electromagnetism valve actuation iron core lower end sealing surface and the valve port.
Background technique
Solenoid valve is a kind of application area gas-liquid Automatic Control Component extremely widely, though its structure and kind are quite various, but its operating principle is all the same substantially, promptly at electrical signal of control circuit input, with regard to magnetic signal of corresponding generation, this magnetic signal drives action of moving iron core generation and opens or close port in the solenoid valve.Distinguish according to structural applications, two kinds of open type and normal close types are arranged, mainly decide during concrete type selecting according to the break-make situation such as pressurized air, water, oil and other media in institute's applicable industry control system, as the control system that is applied to close for a long time, then require to select for use normal close type, it reduces coil heating than open type product energy saving more, increases the service life.In addition in the ordinary course of things, in order to improve sealability, the valve port of solenoid valve is often made tilted conical, to guarantee the good fit with the colloid sealing gasket.But in actual applications, the one, because the deficiency of processing and assembly precision, there is deviation in the perpendicularity on moving iron core axis and valve port plane; The 2nd, because moving iron core frequently moves up and down in the conduit of electromagnetic coil inner chamber, the moving iron core axis in appearance wearing and tearing back produces skew; It is not tight that the colloid sealing gasket that above-mentioned two kinds of situations all easily cause moving iron core lower end and valve port are fitted, and produces leakage phenomenon and increase operational noise, has a strong impact on the sealability of solenoid valve product.
The model utility content
The technical problems to be solved in the utility model is that the perpendicularity that overcomes moving iron core axis that existing like product exists and valve port plane is easy to generate defective and the deficiency that is offset and causes the solenoid valve product hermeticity seriously to descend, provide a kind of energy automatic deviation correction to move the electromagnetic valve product of iron core to society, to improve the sealing valve port performance, reduce impact shock and to reduce operational noise.
The technological scheme that its technical problem that solves the utility model adopts is: direct-acting type comprises valve body, electromagnetic coil and moving iron core from two three-way electromagnetic valves of rectifying a deviation, and described valve body two ends are respectively equipped with import and outlet, and inner chamber is provided with valve port; Described electromagnetic coil inner chamber is provided with and supports the conduit that described moving iron core slides, and described moving iron core lower end mouth outer rim is provided with the pagoda spring; Described moving iron core lower end is provided with step-like cylindrical cavity, is provided with the colloid sealing gasket in the described cylindrical cavity, is provided with the correction spring between described colloid sealing gasket and the described cylindrical cavity bottom surface.
Described conduit lower end is connected to a fixed with the chuck that is embedded at described valve body; Described pagoda spring upper end is supported in described chuck.
The utility model direct-acting type is from rectifying a deviation two three-way electromagnetic valves, and described moving iron core lower end is provided with step-like cylindrical cavity, is provided with the colloid sealing gasket in the described cylindrical cavity, is provided with the correction spring between described colloid sealing gasket and the described cylindrical cavity bottom surface.When deficiency owing to processing and assembly precision, perhaps produce owing to moving iron core frequently moves up and down that wearing and tearing cause moving iron core axis and the valve port plane is not perpendicular in the conduit of electromagnetic coil inner chamber, during the generation deviation, so after the correction spring promotes the colloid sealing gasket, can be subjected to the reaction of valve port end face to produce slightly dislocation by described colloid sealing gasket and finish and the fitting tightly of valve port, thereby effectively improve sealability.Compare than existing product, have be skillfully constructed, simple in structure, convenient and practical advantage.
Description of drawings
Fig. 1 is the utility model product structure schematic representation.
Embodiment
As shown in Figure 1, the utility model direct-acting type comprises valve body 5, electromagnetic coil 1 and moving iron core 3 from rectifying a deviation two three-way electromagnetic valves, and described valve body 5 two ends are respectively equipped with import 9 and outlet 10, and inner chamber is provided with valve port 11; Described electromagnetic coil 1 is connected to a fixed by screw 4 and described valve body 5; Described electromagnetic coil 1 inner chamber is provided with and supports the conduit 2 that described moving iron core 3 slides, and described conduit 2 lower ends are connected to a fixed with the chuck 6 that is embedded at described valve body 5; Described moving iron core 3 lower ends are provided with step-like cylindrical cavity 13, are provided with colloid sealing gasket 8 in the described cylindrical cavity 13, are provided with correction spring 12 between described colloid sealing gasket 8 and described cylindrical cavity 13 bottom surfaces; Be provided with pagoda spring 7 between described moving iron core 3 lower end mouth outer rims and the described chuck 6.
Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.During off-position, described moving iron core 3 is subjected to the double action of self gravitation and described pagoda spring 7, is displaced downwardly to valve port 11 as shown in Figure 1, and promotes described colloid sealing gasket 8 with valve port 11 sealings by described correction spring 12; As the deficiency of this product owing to processing and assembly precision, perhaps produce owing to moving iron core 3 frequently moves up and down that wearing and tearing cause moving iron core 3 axis and valve port 11 planes are not perpendicular in the conduit 2 of electromagnetic coil inner chamber, during the generation deviation, so after described correction spring 12 promotes described colloid sealing gasket 8, can be subjected to valve port 11 end face reactions to produce slightly dislocation by described colloid sealing gasket 8 and finish and the fitting tightly of valve port 11, thereby effectively improve sealability.
