Abstract
The utility model discloses a combined solenoid valve product manufacturing technique, which overcomes the defect of the products in the same type that installation precision of the internal parts of the valve seat can be easily affected by pivoting or welding process, and dissembling for cleaning is not possible after assembling. The valve comprises a valve seat, a valve cover, a solenoid coil and an iron core. The valve seat is provided with an inlet, an outlet and a valve opening. A sealing pad is provided on the lower end of the iron core, the sealing pad corresponds to the axial direction of the valve opening. A guidance bushing is provided outside the iron core. The manufacturing process is characterized in that the valve cover is provided in a platform sediment cavity corresponding to the upper end surface of the valve seat. The lower end of the guidance bushing extends into the inner cavity of the valve cover, and a solenoid coil is sleeved on the upper end. The upper end of the iron core is provided with a central blind hole, and the spring is provided between the central blind hole and the tail seal of the guidance bushing. The spring can also be provided between the flange at the lower end of the iron core and the inner cavity ceiling of the valve cover.

Description
Technical field
The utility model relates to a kind of solenoid valve product manufacturing technology, especially refers to the connection structure of the valve seat of solenoid valve and valve gap, iron core.
Background technique
Electromagnetic valve structure and of a great variety, but its operating principle is the same substantially, and it utilizes magnetic signal to drive iron core and produces an action, opens or close port.Early stage solenoid valve product adopts integral structure, because valve base cavity need be processed a plurality of heavy stands and passage, manufacturing process is more, and manufacturing efficiency is low, cutter consumption is big.The someone had invented a kind of solenoid valve product of split type valve seat afterwards, this type of comparatively typical product as State Intellectual Property Office in notice of authorization on May 3rd, 2006, the patent No. is called " solenoid valve with split type valve seat " utility model patent for the ZL200520100112.0 name, it " comprises and being positioned on the sleeve pipe; the coil at following two ends and valve seat; shutoff is at the end socket and the core iron parts that are positioned at sleeve pipe of sleeve pipe upper end; described valve seat adopts inner inlaying with the outside to form ... when the processing valve base cavity; tool wear is little; burr easily removes, the bigger work efficiency that improved." but the valve seat of this product is inner and riveted joint or welding procedure have been adopted in the outside, and riveted joint or welding process are easy to cause the change of valve seat inner body installation precision, thus influence the quality and the performance of finished parts.And can't disassembly, cleaning and maintenance after the assembling of this product, the user cost height.
The model utility content
The technical problems to be solved in the utility model is to overcome that riveted joint or welding procedure are adopted in that existing like product exists because split type valve seat assembling and very easily influence after valve seat inner body installation precision and the assembling can't disassembly, cleaning and the defective and the deficiency of maintenance, provide the solenoid valve product of a kind of valve seat and valve gap, iron core member assembling and convenient disassembly, profile compact, every performance index of guaranteeing to assemble the rear electromagnetic valve product to society.
The technological scheme that its technical problem that solves the utility model adopts is: combination solenoid valve comprises valve seat, valve gap, electromagnetic coil and iron core, and described valve seat two ends are provided with import and outlet, and inner chamber is provided with valve port; Described iron core lower end is provided with sealing gasket, and described sealing gasket is axially corresponding with described valve port; Described iron core is provided with guide thimble outward; It is characterized in that: described valve gap is located in the heavy stand chamber of described valve seat upper-end surface correspondence; Described guide thimble lower end is inserted into described valve gap inner chamber, the sheathed electromagnetic coil assembly in upper end; Described iron core is connected with spring.
Described iron core upper end is provided with central blind hole, and described spring is located between described central blind hole and the described guide thimble afterbody end socket.
Described iron core lower end mouth is provided with flange, and described spring is located between flange and the described valve gap inner chamber roof.Be embedded seal ring between described valve gap bottom surface and the described valve seat heavy stand chamber root; The axial surface of described iron core is penetrated with groove.
During the assembling of the utility model combination solenoid valve, described valve gap is put into the heavy stand chamber of described valve seat upper-end surface correspondence, get final product by described electromagnetic coil assembly drain pan is fixing then, thereby the high temperature of stress, welding procedure of having avoided riveting process has fully been guaranteed every performance index of assembling rear electromagnetic valve product to the adverse effect of valve seat inner body installation precision; The described valve gap in assembling back places in the described valve seat fully, makes this product design compact, helps the economical with materials cost.Compare than existing product, have be skillfully constructed, simple in structure, convenient and practical advantage.
Description of drawings
Fig. 1 is the utility model embodiment one off-position structural representation.
Fig. 2 is the utility model embodiment two off-position structural representations.
Embodiment
As shown in Figure 1, the utility model combination solenoid valve comprises valve seat 1, valve gap 2, electromagnetic coil 3 and iron core 4, and described valve seat 1 two ends are provided with import 5 and outlet, and inner chamber is provided with valve port 11; Described valve gap 2 is located in the heavy stand chamber of described valve seat 1 upper-end surface correspondence, is embedded seal ring 15 between described valve gap 2 bottom surfaces and the described valve seat 1 heavy stand chamber root; Described iron core 4 lower ends are provided with sealing gasket 6, and described sealing gasket 6 is axially corresponding with described valve port 11; Described iron core 4 outer guide thimble 10 guiding that are provided with; Described guide thimble 10 lower ends are inserted into described valve gap 2 inner chambers 8, and the upper end is arranged with electromagnetic coil 3 assemblies; Described iron core 4 upper ends are provided with central blind hole 14, establish spring 9 between described central blind hole 14 and the described guide thimble 10 afterbody end sockets 13; The axial surface of described iron core 4 is penetrated with groove 12.
Be illustrated in figure 2 as the utility model embodiment two off-position structural representations, its improvements are that described iron core 4 lower end mouth are provided with flange 7, and described spring 9 is located at described flange 7 and described valve gap 2 inner chambers 8 roofs.
Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.During off-position, described iron core 4 is done spring 9 effects, by the sealing gasket 6 that its lower end links to each other described valve port 11 is closed as shown in Figure 1.After electromagnetic coil 3 energisings, move on the described iron core 4 and open valve port 11, conducting between import 5 and the outlet.This product when assembling, described valve gap 2 is put into the heavy stand chamber of described valve seat 1 upper-end surface correspondence, getting final product by described electromagnetic coil 3 assembly drain pans are fixing then; The seal ring 15 of being located at described valve seat 1 heavy stand chamber root can prevent described valve gap 2 inner chambers 8 pressure seepages.After adopting this class fit, the high temperature of stress, welding procedure of having avoided riveting process has fully been guaranteed every performance index of assembling rear electromagnetic valve product to the adverse effect of valve seat inner body installation precision; The described valve gap 2 in assembling back places in the described valve seat 1 fully, makes this product design compact, helps the economical with materials cost.
