Compared with prior art, the utility model has adopted 2 built-in screws to be connected between outlet valve spring seat, import spring valve seat and valve seat, do not needing under the prerequisite of flanging, by two valve spring retainers, be positioned at the design of screw shape cleverly of screw position place, can effectively valve seat be coupled together, and can guarantee operating Security, simultaneously in dismounting and assembling, only need to be after previously screw be screwed into valve seat, rotary outlet valve spring retainer can carry out separation or connection by both, operates very simple.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of outlet spring seat.
In figure, 1 is that outlet valve spring seat, 2 is that outlet valve spring, 3 is that screw, 4 is that outlet valve spool, 5 is that valve seat, 6 is that inlet valve spool, 7 is that inlet valve spring, 8 is that inlet valve spring seat, 9 is that O type back-up ring, 10 is that seal ring, 11 is screw.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
With a quick detachable horizontal combination valve, as shown in Figure 1-2, this combination brake switch and proporting comprises outlet valve assembly, valve seat 5 and inlet valve assembly to its structure, and outlet valve assembly and inlet valve assembly difference level connection joint are at the two ends of valve seat 5.Outlet valve assembly is comprised of outlet valve spring seat 1, outlet valve spring 2 and outlet valve spool 4, outlet valve spring seat 1 is fixed on valve seat 5 through screw 3, outlet valve spring 2 and outlet valve spool 4 are arranged on valve seat 5, and outlet valve spring seat 1 heads on outlet valve spool 4 by outlet valve spring 2 and presses on valve seat 5.Inlet valve assembly is comprised of inlet valve spring seat 8, inlet valve spring 7 and inlet valve spool 6, inlet valve spring seat 8 is fixed on valve seat 5 through screw 11, inlet valve spring 7 and inlet valve spool 6 are arranged on valve seat 5, and inlet valve spring seat 8 heads on inlet valve spool 6 by inlet valve spring 7 and presses on valve seat 5.In the outside of outlet valve spring seat 1, valve seat 5 and inlet valve spring seat 8, be provided with O type back-up ring 9 and seal ring 10.
When mounted, valve seat 5 and inlet valve spring seat 8 are fixing by screw 11 for the utility model, and valve seat 5 is connected by screw 3 with outlet valve spring seat 1.It is as a whole that combination brake switch and proporting after connection just becomes.During installation, can first inlet valve spool 6 and inlet valve spring 7 be loaded in valve seat 5, again inlet valve spring seat 8 is connected by screw 11, in like manner outlet valve spool 4 and outlet valve spring 2 are also loaded in valve seat 5, and first screw 3 is screwed on valve seat 5, then put outlet valve spring seat 1, and pack into screw by the screw big hole of outlet valve spring seat 1, the outlet valve spring seat 1 that turns clockwise again immediately can connect upper valve base 5, corresponding installation each O type back-up ring 9 and seal ring 10.In pump operation process, even if outlet valve spring seat 1 has been rotated counterclockwise, screw also can not be deviate from, because outlet valve spring seat 1 does not have screw 3 to screw out the space getting loose, has guaranteed the reliability of this invention.In addition, due to screw 3 small volumes, and the radial space itself occupying is limited, and the guiding that can make to export valve core 4 is thicker, and outlet valve spring 2 diameters are also larger, guarantee that overall operation is steady.
Structure before contrast, outlet spring seat and valve seat are that the seam rotation by inlaying is connected, although connect, be also easy to, because of spatial axes to distance limited, make to export the seam that two of spring seat and valve seat inlay very thin, easily fracture, and due to the existence of seam, make radially outlet valve and spring thereof do not quite, spool is comparatively weak, less stable while causing moving, easily vibrates, and occurs fracture and the broken phenomenon of spool thereof of spring; Also having structure is to adopt screw to connect, although valve inner space is also comparatively well-to-do, solved the deficiency of said structure, screw is fixed whole valve body, when dismounting, must first turn on screw and could dismantle valve body, dissembling inspection has been caused to some inconvenience.Structure after improvement is since being used, and dismounting is time saving and energy saving, safe and reliable to operation.
The structure of outlet valve spring seat 1 as shown in Figure 3, outlet valve spring seat 1 bottom opening position is corresponding with the screwhole position of valve seat 5, openings of sizes and screw 3 match, be that axis of great circle should be greater than screw 3 head diameters, axis of small circle should be greater than screw 3 major diameter of threads and be less than screw 3 head diameters, guarantee after screw 3 is first screwed on valve seat 5, big hole by outlet valve spring seat 1 overlaps screwing 3, and rotary outlet valve spring retainer 1 can connect upper valve base 5, because whole combination brake switch and proporting is compressed by valve gland in pump head, therefore do not worry that combination brake switch and proporting in service can play and screw 3 meeting back-outs.While opening and inspecting valve group, need not turn on screw 3, the outlet valve spring seat 1 that only need to turn clockwise just can separately check valve seat 5 and outlet valve spring seat 1, very convenient.
