Abstract
The utility model discloses a one-way valve core for an integrated hydraulic control multi-way valve, which comprises a valve core body (1) and is characterized in that the cone edge of an end part (1.1) of the valve core body (1) matched with an oil through hole (3) of an integrated hydraulic control multi-way valve body (2) on the longitudinal profile of the central line of the valve core body adopts a circular arc edge. The one-way valve core ensures that the end part of the valve core body is completely matched with the oil through hole of the integrated hydraulic control multi-way valve body, and the sealing effect is good.
Description
Technical field
The utility model relates to the hydraulic element in a kind of hydraulic machinery, specifically is a kind of nonreturn valve core of integrated type hydraulic control multi-way valve.
Background technique
The nonreturn valve core of present integrated type hydraulic control multi-way valve, comprise the spool body, the valve body oil through of the end of this spool body and integrated type hydraulic control multi-way valve matches, and described end is taper, promptly the awl limit in the longitudinal section of heart line is a straight flange therein, and described valve body oil through is a manhole.Because this spool body only relies on pushing of the spring that is enclosed within afterbody, described end and valve body oil through are offseted to reach sealing effect, as seen this structure is radially not spacing, when spool body top puts in place, its axis is difficult to axis with the valve body oil through on same straight line, so this will cause the valve body oil through of the end of spool body and integrated type hydraulic control multi-way valve not exclusively to match and cause sealing effect poor.
The model utility content
The technical problems to be solved in the utility model is, overcome the defective of above prior art, provide a kind of end of spool body and valve body oil through of integrated type hydraulic control multi-way valve of making to match fully, and the nonreturn valve core of the integrated type hydraulic control multi-way valve of good sealing effect.
The technical solution of the utility model is, a kind of nonreturn valve core of integrated type hydraulic control multi-way valve is provided, and comprises the spool body, and the end that the oil through of described spool body and integrated type hydraulic control multi-way valve valve body the matches side in the longitudinal section of heart line therein is the circular arc limit.
After adopting above structure, the utility model compared with prior art, have the following advantages: since the end that the oil through of described spool body and integrated type hydraulic control multi-way valve valve body matches therein the side in the longitudinal section of heart line be the circular arc limit, the side that is to say the end is a sphere, by basic geometric knowledge as can be known, when spool body top puts in place, even the axis of its axis and valve body oil through is not on same straight line, the end of this spool body still can match fully with the valve body oil through, and reaches extraordinary sealing effect.
Description of drawings
Fig. 1 is the structural representation of the nonreturn valve core of integrated type hydraulic control multi-way valve of the present utility model.
Fig. 2 is the structural representation that the nonreturn valve core of integrated type hydraulic control multi-way valve of the present utility model cooperates with valve body.
Shown in the figure 1, the spool body, 1.1, the end, 2, valve body, 3, oil through, 4, spring.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the nonreturn valve core of integrated type hydraulic control multi-way valve of the present utility model, comprise spool body 1, the end 1.1 that the oil through 3 of described spool body 1 and integrated type hydraulic control multi-way valve valve body 2 the matches side in the longitudinal section of heart line therein is the circular arc limit, it is described end 1.1 cuts upper end part and fraction end portion for spheroid intermediate section, the side that is to say the end is a sphere, can match with oil through 3 multi-angles and seal like this.
As shown in Figure 2, the afterbody of described spool body 1 is with spring 4, and an end of spring 4 and the bottom surface of end 1.1 offset, and its other end and valve body 2 offset, and the effect by spring 4 makes the end 1.1 of spool body 1 cooperate with oil through 3, reaches sealing or one-way flow.
Claims (1)
1, a kind of nonreturn valve core of integrated type hydraulic control multi-way valve, comprise spool body (1), it is characterized in that: the end (1.1) that the oil through (3) of described spool body (1) and integrated type hydraulic control multi-way valve valve body (2) the matches awl limit in the longitudinal section of heart line therein is the circular arc limit.
