Abstract
The solenoid valve guide head includes a magnetic isolating pipe holding static iron core assembly and movable iron core assembly and a pedestal. It features the integrally drawn structure of the magnetic isolating pipe and the pedestal. The integral structure results in the advantages of no leakage, fast and compact structure, small size, high corrosion resistance, high performance, etc. and may raise the integral quality of solenoid valve greatly.
Description
Technical field
The present invention relates to the solenoid valve technical field, specifically be meant the architecture advances of electromagnetic valve guide head.
Background technique
Pilot head is a kind of actuator of the usefulness that matches with solenoid valve, it have the base that partly is connected with valve body and in be used for the plunger tube of quiet, the moving core assembly of device.At present owing to be subjected to the restriction of conditions such as technology, equipment, all be after making base and plunger tube respectively earlier, adopt welding procedure that both are welded into whole first catheter block, thereby have the defective poor because of leakage, resistance to pressure that welding causes, that outward appearance is coarse etc., and finally cause the quality of solenoid valve to descend.How to address the aforementioned drawbacks, also do not have the pertinent literature record by retrieval.
Summary of the invention
Technical problem to be solved by this invention be provide at above-mentioned prior art present situation a kind of good airproof performance, high pressure resistant, volume is little, the electromagnetic valve guide header structure of in light weight, improvement that outward appearance is exquisite.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: this electromagnetic valve guide head improved structure, include plunger tube and base, static iron core assembly and moving core assembly are housed in the plunger tube, it is characterized in that described plunger tube and base are the integrated type structure of integrally stretching.
Also be formed with the groove that to set seal ring on the described base.
Compared with prior art, the invention has the advantages that: adopt unjointed integrated type structure, overcome because of leakage that welding causes, and influenced the problem of fastness etc., made it to have that compact structure, volume are little, good seal performance, corrosion protection, acid resistant alkali, high temperature resistant, high pressure resistant, in light weight, performance is good, the advantage of outward appearance exquisiteness etc., can significantly improve the total quality of solenoid valve thus.

Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
See Fig. 1, shown in Figure 3, the plunger tube 11 of the first catheter block 10 of pilot head of the present invention and the jointing type structure of base 12 for making through specific drawing craft do not have weld seam between plunger tube 11 and the base 12.Base 12 is rounded, and its bottom is integrally formed fluted 13, can set seal ring in when partly being connected with valve body.The static iron core assembly 30 and the moving core assembly 20 that weld mutually with plunger tube are housed, as shown in Figure 3 in the plunger tube 11.And Fig. 1, pilot head shown in Figure 2, the static iron core assembly 30 in the plunger tube is welded in after the extruding earlier with plunger tube 11 again.
As shown in Figure 4, electromagnetic valve guide head 3 of the present invention cooperates with valve body 1, and seal ring 2 is equipped with in the cooperation place, loads onto coil and terminal box 4, connects with screw 5 to compress again, and makes this direct action solenoid valve more embody attractive in appearance, the compact superiority of one base.
As shown in Figure 5, electromagnetic valve guide head 3 of the present invention ' elder generation with valve body 1 ', diaphragm unit 6, valve gap 7 be assemblied in, be equipped with between valve gap and the pilot head Sealing 2 ', compress with pressing plate 8 again, after putting case 9, loading onto winding wiring box 10, compress with nut 11 again.
By the designed electromagnetic valve guide head of the present invention, with being connected of valve body part, no matter adopt which kind of Placement, can both embody the superiority of base one, make solenoid valve general structure compactness, easy to assembly, total quality raising, as shown in Figure 3.
Claims (2)
1, a kind of electromagnetic valve guide head improved structure, the first catheter block that includes plunger tube (11) and base (12), static iron core assembly (30) and moving core assembly (20) are housed in the plunger tube, it is characterized in that: described plunger tube (11) and base (12) are the integrated type structure of integrally stretching.
2, electromagnetic valve guide head improved structure as claimed in claim 1 is characterized in that: also be formed with the groove (13) that can set seal ring on the described base (12).
