Abstract
A steel ball type shuttle valve structure comprises a valve body and a valve core, wherein the valve core is composed of a valve seat, a shuttle valve sleeve and a steel ball. The left and right valve seats are provided with channels respectively communicated with the left and right inlets on the valve body, the middle part of the shuttle valve sleeve arranged between the left and right valve seats is provided with a channel communicated with the upper outlet of the valve body, the steel ball is positioned in the inner hole of the shuttle valve sleeve and can freely roll, and the spherical surface of the steel ball is matched with the valve line of the inner side port of the channel on the valve seat. When the oil enters the port A, the steel ball moves to the right, A-P2Communicating, and sealing the port B; when oil enters the port B, the steel ball moves to the left, B-P2And the opening A is closed and used in a manual valve to play the role of a shuttle valve. The utility model has low requirement on the part processing precision and reduced production cost; the phenomena of blocking and leakage are avoided, and the reliability is high.
Description
Technical field
The utility model relates to a kind of hand than shuttle valve structure in the combination valve, particularly steel ball type shuttle valve structure.
Background technique
In manual ratio direction of the traffic combination valve, be unable to do without the control action of shuttle valve, it can connect automatically respectively different ingress liquid medium flow to passage.Traditional shuttle valve structure comprises valve body, valve core of the spool valve, plug, as shown in Figure 1.When the oil-feed of A mouth, spool 1 is pushed the right side to, A-P
2Connect, the B mouth is shut; When the oil-feed of B mouth, spool 1 is pushed left side, B-P to
2Connect, the A mouth is shut.In this structure, because spool 1 is free to slide in valve body 2, obvious part requirement on machining accuracy height in addition causes cost of production to rise; Turbidity test requirement to hydraulic oil is also higher, in case foreign matter is arranged, spool is easily stuck, cisco unity malfunction; Simultaneously always there is matching gap, causes and leak oily phenomenon, thereby have influence on the reliability of shuttle valve.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and what provide that a kind of cost is low, reliability is high is used for the steel ball type shuttle valve structure of hand than combination valve.
The technical solution of the utility model is: steel ball type shuttle valve structure comprises valve body and spool, inlet about having on the valve body, between two inlets outlet is arranged, passage is arranged on the spool, be communicated with left entry and outlet, seal right entry this moment, perhaps is communicated with right entry and outlet, seals left entry this moment.Improvements are that described spool comprises valve seat, shuttle valve sleeve, steel ball, valve seat is symmetrical set, contact with the valve pocket sealing of valve body, left and right valve seat is provided with the passage that is connected with left and right inlet on the valve body respectively, there is the passage that is connected with the valve body upper outlet intermediate portion that is arranged on the shuttle valve sleeve between the left and right valve seat, steel ball is arranged in the endoporus of shuttle valve sleeve, and its diameter is less than the shuttle valve sleeve internal diameter, greater than the aperture of the inboard port of left and right valve seat upper channel.
On the outer surface of above-mentioned valve seat seal ring is housed.The inboard port valve line of valve seat upper channel becomes arc surface, matches with the sphere of steel ball.
Adopt technique scheme, the Spielpassung of original valve core of the spool valve is moved the rolling that changes steel ball into, play the effect of shuttle valve.The requirement on machining accuracy of valve seat, shuttle valve sleeve reduces, and cost of production descends, and the turbidity test to hydraulic oil require also to reduce simultaneously, can not cause stuck phenomenon, can avoid leaking the drawback of oil again, and system reliability is strengthened greatly.
Description of drawings
Fig. 1 is for adopting the shuttle valve structural representation of valve core of the spool valve;
Fig. 2 is the utility model steel ball type shuttle valve structural representation.
Embodiment
The present embodiment Combination Design is on safety valve, and the inner chamber of valve body 2 is provided with left and right valve seat 3, both sides have plug 7, valve seat be provided with respectively with valve body on about the passage that A, B be connected that enters the mouth, the valve seat outer surface has seal ring 6.Be provided with shuttle valve sleeve 4 between two valve seats, the shuttle valve sleeve intermediate portion have with valve body on go out P
2The passage that is connected.Steel ball 5 freely rolls at the shuttle valve sleeve inner chamber, and the arc surface of the inboard port valve line of the sphere of steel ball and valve seat upper channel matches.Among Fig. 2, when the oil-feed of A mouth, steel ball rolls valve seat to the right, A-P
2Connect, the B mouth is shut, and when the oil-feed of B mouth, steel ball rolls valve seat left, B-P
2Connect, the A mouth is shut, and plays the shuttle valve effect.
Claims (3)
1, a kind of steel ball type shuttle valve structure, comprise valve body and spool, a left side is arranged on the valve body, right entry, between two inlets outlet is arranged, passage is arranged on the spool, be communicated with left entry and outlet, seal right entry this moment, perhaps be communicated with right entry and outlet, seal left entry this moment, it is characterized in that described spool comprises valve seat, shuttle valve sleeve, steel ball, valve seat is symmetrical set, contact with the valve pocket sealing of valve body, a left side, right valve seat be provided with respectively with valve body on a left side, the passage that right entry is connected is arranged on a left side, there is the passage that is connected with the valve body upper outlet intermediate portion of the shuttle valve sleeve between the right valve seat, and steel ball is arranged in the endoporus of shuttle valve sleeve, its diameter is less than the shuttle valve sleeve internal diameter, greater than a left side, the aperture of the inboard port of right valve seat upper channel.
2,, it is characterized in that on the outer surface of valve seat seal ring being housed by the described steel ball type shuttle valve of claim 1 structure.
