Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.Should be understood that, embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
According to an aspect of the present utility model, referring to Fig. 3 to Fig. 5, a kind of valve body is provided, in this valve body, offer hydraulic fluid port silk hole 1, hydraulic fluid port silk hole 1 forms hydraulic fluid port at upper surface 6 places of valve body, and wherein, hydraulic fluid port has the seam 2 around hydraulic fluid port around, the bottom surface of seam 2 is lower than upper surface 6, and seam 2 is communicated with at least one side surface of valve body.
As mentioned above, because the bottom surface of the hydraulic fluid port of valve body seam 2 is around lower than upper surface 6, seam 2 is communicated with at least one side surface of valve body, and because hydraulic fluid port silk hole 1 and seam 2 can process on same equipment, so above-mentioned valve body had both guaranteed the perpendicularity of hydraulic fluid port silk hole 1 with the bottom surface of seam 2, can make again the ponding at seam 2 places can be in time by the connectivity part of side surface and seam 2, discharge to prevent that seam 2 places from getting rusty, thereby greatly improve the sealing of oil port and the working life of valve body.
According to a mode of execution of the present utility model, as shown in Figure 3, preferably, the upper surface 6 of valve body offers slot part 5, slot part 5 can just be cast and form when valve body blank is cast, certainly, if be inconvenient to cast slot part 5, also can be by suitable method processing slot parts 5 such as Milling Process, and one end of slot part 5 is communicated with seam 2, the other end is communicated with a side surface of valve body, and wherein, one end that slot part 5 is communicated with seam 2 should and hydraulic fluid port between there is certain distance to guarantee the sealing of oil port, like this, ponding in seam 2 can be by way of slot part 5, by the connectivity part of side surface and seam 2, discharge.Although show in Fig. 3 that seam 2 places only offer a slot part 5, but it is not limited to the utility model, that is to say, in order to reach better drainage effect, can also correspondingly offer a plurality of slot parts 5 at seam 2 places, as long as can guarantee the intensity of valve body and meet the budget of processing cost.In order to make the ponding in seam 2 enter smoothly slot part 5, the bottom surface of slot part 5 is lower than the bottom surface of seam 2, and is usually less than the bottom surface 1mm to 2mm of seam 2, but the utility model is not limited to this.In addition, for ponding is better discharged, the bottom surface of slot part 5 can be from seam 2 a downward-sloping (see figure 4) of side surface towards valve body.Here it should be noted that, offer slot part 5 and be particularly useful for hydraulic fluid port apart from the distant situation of the side surface of valve body, but be not limited to use in this case.
According to another mode of execution of the present utility model, as shown in Figure 5, seam 2 can directly be communicated with at least one side surface of valve body.Such setting, owing to no longer needing to offer the slot part 5 that is specifically designed to draining, therefore simpler according to another mode of execution valve body structure of the present utility model, and due to ponding approach intermediate section (slot part 5) no longer, therefore can avoid the phenomenon that cannot discharge because of the ponding that intermediate section (slot part 5) appearance obstruction waits fortuitous event to cause, thereby make the discharge of ponding more smooth and easy.In addition, preferably, upper surface 6 can be rectangular, seam 2 can be for having the ring of cylindrical and inner circle, and the center of circle of seam 2 is all less than the exradius of seam 3 to the distance of two side surfaces along described rectangular width direction of valve body, can guarantee that like this seam 2 is directly communicated with two side surfaces along described rectangular width direction of valve body, to obtain the effect of better discharge ponding, and when the center of circle of seam 2 equates to the distance of two side surfaces along described rectangular width direction of valve body, this valve body is neat appearance more.Here it should be noted that, seam 2 is arranged to directly be communicated with and be particularly useful for hydraulic fluid port apart from the situation of the close together of the side surface of valve body with the side surface of valve body, but is not limited to use in this case.In addition; the above-mentioned technological scheme that seam 2 is directly communicated with at least one side surface of valve body is combined and can form another mode of execution of the present utility model (not shown) with the technological scheme that offers slot part 5; this combination obviously should fall into protection domain of the present utility model; so not only can take into account the advantage of the two, also make valve body Applicable scope of the present utility model wider.
According to another aspect of the present utility model, a kind of hydrovalve is provided, wherein, this hydrovalve comprises the valve body described in technique scheme.Thus, improved the working life of this hydrovalve.
According to another aspect of the present utility model, a kind of engineering machinery is provided, comprise hydraulic system, wherein, in described hydraulic system, at least there is the hydrovalve described in such scheme.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition each the concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
In addition, between various mode of execution of the present utility model, also can carry out combination in any, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
