Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 2, a kind of convenient controller panel sealing configuration installed, it is applicable to the sealing between the mating face of control panel in the electronic pressure controller of water pump and the mating face of housing.Specifically comprise the control panel 1 of an injection-moulding plastic, the surrounding edge 12 that control panel comprises plate body 11 and extended by the direction that edge is approximately perpendicular to plate body integratedly, edge of plate body, thus be conducive to the demoulding of control panel when injection moulding.Arrange protruding rib 13 at the outer ledge place of the surrounding edge end face of control panel, thus form the seal groove 14 opened with the inner side surface of surrounding edge at the end face of surrounding edge, correspondingly, namely the end face of rib forms the mating face engaged with housing.In seal groove, correspondingly arrange the seal washer 2 of annular, seal washer can be made up of silica gel, thus makes it have enough elasticity.As shown in Figure 3, seal washer comprises the annular circle body 21 of rectangular one of cross section, the profile of circle body and the inner side surface adaptation of rib, circle body upper side and downside arrange some circle ring ribs 22 respectively, the cross section of ring rib is rectangular, the axis of the axis of the ring rib of outer ring and the ring rib of inner ring forms offset relationship, thus makes between arbitrary two adjacent rings ring rib equal in the spacing of the Normal direction of ring rib.The rectangular annular groove of cross section 23 is formed between two adjacent rings ring rib, the width of annular groove should be greater than the width of ring rib, and the ring rib on the upper side of seal washer and the ring rib on downside misplace in Normal direction and arrange, that is, annular groove on upper side is just corresponding with the ring rib on downside, and ring rib on upper side is just corresponding with the annular groove on downside.
During installation, ring rib on the circle body upper side of seal washer contacts with the seal groove bottom surface on control panel, ring rib on circle body downside then contacts with the mating face of housing, after control panel is connected by screw fastening with housing, can realize the sealing between control panel and housing, the mating face on control panel rib now engages with the mating face of housing.Be understandable that, the thickness of whole seal washer, namely the thickness of circle body adds that the height of the ring rib of upper and lower both sides should be greater than the degree of depth of seal groove, thus make seal washer when mounted by extruding to a certain extent, now, ring rib is crushed on the one hand, on the other hand, the ring rib be squeezed slightly sinks to the annular groove side of opposite side, thus avoids the ring rib on seal washer to be subject to excessive compression, guarantees that seal washer is in regime of elastic deformation.
In order to improve sealing effect, as shown in Figure 3, Figure 4, the cross section of circle body also can be made C shape by us, particularly, circle body comprises the upper seal ring 211, the lower seal 212 that fit together, upper seal ring, lower seal are flat, are linked into an integrated entity between the outer ledge of upper seal ring, lower seal by attachment ring 213.In addition, the faying surface of upper and lower seal ring arranges some cross sections vee gutter triangular in shape 24 respectively, vee gutter on upper seal ring and the vee gutter in lower seal extend out to attachment ring along the Normal direction of circle body from the inner side surface of circle body respectively, and the vee gutter on upper seal ring docks with the vee gutter in lower seal the rhombus groove forming cross section and assume diamond in shape up and down.Vee gutter interval on upper and lower seal ring is arranged, thus on the faying surface of upper and lower seal ring, namely forms docking up and down between adjacent two vee gutters and cross section is the trapezoidal raised line 25 of isosceles trapezoid.Like this, when pump working, the water in electronic pressure controller with pressure can enter in upper seal ring, lower seal from the rhombus groove of circle body inside edge, thus corresponding extruding force is formed to upper seal ring, lower seal, and then make seal ring be close to control panel, lower seal is close to housing, be conducive to improving sealing effect further.It should be noted that, cross section is that trapezoidal trapezoidal raised line both can form good support to upper seal ring, lower seal, guarantee that ring rib on seal washer and control panel and housing form enough pressure, to avoid leaking, the fitting area between upper and lower seal ring can be reduced simultaneously as far as possible, thus make the press water in electronic pressure controller form enough extruding forces to upper and lower seal ring, and this extruding force increases progressively along with the rising synchronous of electronic pressure controller internal water pressure, thus can guarantee sealing effect.
Further, we also can arrange the annular through groove 26 that a circle is communicated with each vee gutter on the faying surface of upper and lower seal ring, thus can guarantee that the water pressure in the rhombus groove between upper and lower seal ring is identical, and then make the sealing effect forming stable and consistent between seal washer and control panel and housing.
Finally, we can make the height of each ring rib on circle body progressively increase from the inside to the outside.Like this, when not having press water in control panel, the extruding force on circle body suffered by each ring rib progressively increases progressively from the inside to the outside.When press water enters in vee gutter, can strut like a cork under the effect of press water between upper and lower seal ring inside circle body and be close to control panel and housing, and the outside of seal washer due to attachment ring effect its to strut amount of deformation relatively little, thus the strut extruding force of press water to upper and lower seal ring is progressively reduced from the inside to the outside, and then whole seal washer is made to form comparatively evenly a burst of sealing effect from the inside to the outside.
