Abstract
The utility model discloses a supporting plate for a valve. The supporting plate comprises a square supporting plate body (1); a central round hole (2) is formed in the center of the supporting plate body (1); two opposite edges of one end face of the supporting plate body (1) are formed into inclined surfaces (3), and chamfers (6) are formed at the two ends of each of the inclined surfaces (3) in the length direction; at least one oil injecting hole (5) is formed in the two side surfaces of the supporting plate body (1), and communicated with the central round hole (2). With such a structure, the structure of the inclined surfaces is formed at one pair of opposite edges of the edges of the supporting plate, so that the supporting plate can be guided by use of the inclined surfaces while being mounted, and therefore, the supporting plate is simpler and more accurate to assemble, and consequently, the assembly efficiency is greatly improved.
Description
Technical field
The utility model relates to the technical field of valve, is specifically a kind of for the dunnage on valve.
Background technique
In the structure composition of valve, use sometimes dunnage, it is arranged in the valve pocket in valve body, is socketed on valve rod and with valve rod and forms and be slidably matched, and plays the effect of supported spring.The dunnage of prior art is one flat plate, and centre is the center hole coordinating with valve rod, and its edge is straight right angle, and therefore, the dunnage of this structure exists following shortcoming:
1) because the edge of dunnage is right angle, therefore, in assembly process, these right angles can affect the importing of assembling, thereby the phenomenon that assembling is difficult occurs;
2) because the center hole of dunnage coordinates with valve stem slides, and dunnage and valve rod are all metal, and therefore, the friction producing between the two, after long-time use, can produce wearing and tearing, or the stuck phenomenon of sliding occurs.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of and assemble simply, be slidably matched smoothly for the dunnage on valve.
For solving the problems of the technologies described above, the utility model provide for the dunnage on valve, comprise the dunnage body being square, the center of dunnage body has center hole; Two opposite side of described one of them end face of dunnage body are inclined-plane, and two ends in the longitudinal direction, inclined-plane all have chamfering; On two sides of dunnage body, have at least one oil hole, described oil hole communicates with center hole.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
1) owing to having adopted the structure on inclined-plane on one of them opposite side of support plate edge, make dunnage utilize when mounted inclined-plane to have an effect for guiding, therefore, make assembling more simple, accurate, greatly improve efficiency of assembling;
2) increased oil hole in dunnage side, made lubricant oil enter center hole by oil hole, therefore, with being slidably matched of valve rod in, had the lubricated of lubricant oil, reduce on the one hand the wearing and tearing of part, prevent on the other hand the stuck phenomenon of valve rod.
As improvement, the intermediate portion on described each inclined-plane all has oil guide slot, and one end and the center hole of oil guide slot join.Adopt after this structure, lubricant oil unnecessary in center hole is flowed out by oil guide slot, therefore, prevent because occur that lubricant oil too much produces the phenomenon of viscous.
As further improvement, the quantity of described oil hole is three, and on the in alignment side that is evenly distributed on dunnage body, three oil holes all communicate with center hole.This is due in the time that the size of valve member is larger, can give in time dunnage and enough lubricant oil is provided coordinating of valve rod.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
From the structural representation for the dunnage on valve shown in Fig. 1～Fig. 4, it comprises the dunnage body 1 being square, and the center of dunnage body 1 has center hole 2.Two opposite side of described dunnage body 1 one of them end face are inclined-plane 3, and two ends in the longitudinal direction, inclined-plane 3 all have chamfering 6.On two sides of dunnage body 1, have at least one oil hole 5, described oil hole 5 communicates with center hole 2.
The intermediate portion on described each inclined-plane 3 all has oil guide slot 4, and one end of oil guide slot 4 and center hole 2 join.
The quantity of described oil hole 5 is three, and on the in alignment side that is evenly distributed on dunnage body 1, three oil holes 5 all communicate with center hole 2.
Claims (3)
1. for the dunnage on valve, comprise the dunnage body (1) being square, the center of dunnage body (1) has center hole (2); It is characterized in that: two opposite side of described one of them end face of dunnage body (1) are inclined-plane (3), and inclined-plane (3) two ends in the longitudinal direction all have chamfering (6); On two sides of dunnage body (1), have at least one oil hole (5), described oil hole (5) communicates with center hole (2).
2. according to claim 1 for the dunnage on valve, it is characterized in that: the intermediate portion on described each inclined-plane (3) all has oil guide slot (4), one end of oil guide slot (4) and center hole (2) join.
3. according to claim 1 for the dunnage on valve, it is characterized in that: the quantity of described oil hole (5) is three, and on the in alignment side that is evenly distributed on dunnage body (1), three oil holes (5) all communicate with center hole (2).
