Further, the electromagnetism four-way change-over valve that the application provides, including the D connection being connected with main valve body, D connection is bend pipe, and this bend pipe includes the vertical section parallel with the axis that S takes over the horizontal segment of main valve body connection and axis.
The horizontal segment of the main valve body in the application and the axis perpendicular of S adapter, have certain difficulty man-hour adding, add the cost of processing；If it addition, the capacity of valve body increases, the length of main valve body and diameter are also required to increase a lot, and other parts are also required to increase accordingly so that cost increase is too fast.
Refering to shown in Fig. 1 and Fig. 2, this prior art provides a kind of electromagnetism four-way change-over valve, including: main valve body 16 and guide valve blocks 10, wherein, main valve body 16 has the main valve chamber of cylindricality, being provided with radial direction through hole 33 on the wall of this main valve chamber, the axis of radial direction through hole 33 can be through the axial centre of main valve body 16, it is also possible to be offset slightly from the axial centre of main valve body 16；Being additionally provided with S adapter 29 on main valve body 16, one end of S adapter 29 connects with main valve body 16, and the axis co-planar of the axis of this S adapter 29 and radial direction through hole 33；Guide valve blocks 10 has pilot valve chamber axially extending with radial direction through hole 33, guide valve blocks 10 is directly connected to main valve body 16, and first end in pilot valve chamber connects with main valve chamber, and second end in pilot valve chamber is provided with coaxial conduit 32, wherein, connected by radial direction through hole 33 between pilot valve chamber and main valve chamber.
Guide valve blocks 10 is directly connected with main valve body 16, without using support and Zhi Gai etc. to support attachment structure, simplify the connection of cross valve, and, owing to main valve body 16 is directly connected by radial direction through hole 33 with guide valve blocks 10, the D capillary tube between connection D connection and guide valve blocks 10 can be saved, the cost of electromagnetism four-way change-over valve can be reduced further, and the shock resistance of main valve and pilot valve can be improved, improve the reliability of electromagnetism four-way change-over valve.
As shown in Figure 3 and Figure 4, as the optional embodiment of one, first end of guide valve blocks 10 is formed with the arcs of recesses end face 10a matched on the convex surface with main valve body 16, this arcs of recesses end face 10a can be Closed End (as shown in Figure 3), during installation, first the outer surface of the arcs of recesses end face 10a of guide valve blocks 10 with main valve body 16 can be welded together, punch to main valve body 16 from pilot valve intracavity the most again, the radial direction through hole 33 of axially extending bore 10c and main valve body 16 is got through simultaneously, the most i.e. ensure the axiality of two through holes, in turn ensure that two through holes can have identical diameter, and ensure that being reliably connected and sealing between guide valve blocks 10 and main valve body 16.Certainly, in order to realize the connection between guide valve blocks 10 and main valve body 16, it is also possible to be provided with the axially extending bore 10c(coaxial with radial direction through hole 33 on arcs of recesses end face 10a as shown in Figure 2 in advance).The diameter of axially extending bore 10c can be less than or equal to the diameter of radial direction through hole 33.If axially extending bore 10c is less than the diameter of radial direction through hole 33, assembling of being more convenient for, and it is not easy blocking when two axis hole deflections.
As shown in Figure 5 and Figure 6, the first end of guide valve blocks 10 is formed and boss portion 10b of radial direction through hole 33 interference fit, and this boss portion 10b is formed with the axially extending bore 10c coaxial with radial direction through hole 33.During installation, first can stamp axially extending bore 10c in boss portion 10b, axially extending bore 10c should be coaxial with the bearing of trend of guide valve blocks 10, then boss portion 10b interference fit is encased in the radial direction through hole 33 of main valve body 16, it is achieved the connection between guide valve blocks 10 and main valve body 16.Actually, boss portion 10b of guide valve blocks 10 can also be for the state not having through hole shown in Fig. 7 before being installed on main valve body 16, in such cases, after boss portion 10b is installed to radial direction through hole 33 inside, on boss portion 10b, the axially extending bore 10c coaxial with radial direction through hole 33 is offered again in guide valve blocks 10, the effect that two ways is reached is all identical, can select any one according to the condition of processing.
When using boss portion 10b to realize connecting with the mode of radial direction through hole 33 interference fit between guide valve blocks 10 with main valve body 16, in order to improve reliability and the sealing property of the connection between guide valve blocks 10 and main valve body 16, the side that main valve body 16 is relative with guide valve blocks 10 is formed with arcs of recesses side, and the first end of guide valve blocks 10 is formed with the convex end face matched in the arcs of recesses side with main valve body 16.Now, boss portion 10b becomes the part that the first end of pilot valve cavity 10 is the most prominent, radial direction through hole 33 defines a pit on main valve body 16, and boss portion 10b extend into the inside of main valve body 16 by this pit, it is achieved the connection between guide valve blocks 10 and main valve body 16.
It addition, the slide block in the present invention relies primarily on what the promotion of gases at high pressure was moved.As can be seen here, although the application eliminates the connection support between main valve body with guide valve blocks, a lid and the D capillary tube connecting between main valve body and guide valve blocks, simplify the attachment structure between guide valve blocks and main valve body, and the reliability being connected between guide valve blocks with main valve body can be increased, increase the vibration resistance of each valve body, reduce the cost of reversal valve, can be in this type of design, increase along with valve body capacity, the length of main valve body and diameter are also required to increase a lot, other parts are also required to increase accordingly so that cost materials are more, and cost increase is too fast.
