Abstract
The utility model relates to a fast joint for high pressure oil pipes. The fast joint for high pressure oil pipes is characterized in that springs of which the elastic forces are respectively regulated by an upper regulating nail and a lower regulating nail are arranged on an upper and a lower valve bodies (1, 12); two valves (9, 10) which are used for closing oil openings of an upper and a lower main bodies (1, 12) are butted by the elastic forces of the springs; at the time of butt joint, the valves (9, 10) are mutually butted, and oil passages in the upper and the lower main bodies (1) (12) are communicated; an annular groove which is matched with a positioning steel ball 14 is arranged on the upper main body (1), therefore, the upper main body and the lower main body can relatively rotate. The utility model has the advantage of convenient shifting and connection. The utility model is widely suitable for fast communicating the oil passages and fast disconnecting the oil passages between a hydraulic pipe passage and hydraulic equipment.
Description
The utility model relates to a kind of high-pressure oil pipe rapid pipe joint that is used for connecting oil circuit between hydraulic pipe line (high-pressure rubber pipe) and the hydraulic equipment fast and disconnects oil circuit fast.
When the hydraulic pipe line connecting head is used in frequent changing-over, generally be to adopt ordinary couplings, when needing disconnection or connecting oil circuit, all to tighten or Panasonic, can delay a lot of operating times, the general rapid pipe joint of using with wrench, taking away Shi Huixiang outflow oil, oil dripping, pollute the work-yard, and with the applying working condition difference, in use oil pipe often coils hinge.
The purpose of this utility model just provides a kind of pulling out and connects conveniently, and to outflow oil, oil dripping phenomenon, joint can be followed oil pipe and be rotated in the time of can not occurring dismantling, and avoids dish hinge phenomenon high-pressure oil pipe rapid pipe joint easy to use to occur.
Solution of the present utility model is such: be made of last main body 1, following main body 12, overcoat 5 and spring 6, in last main body 1, be provided with the valve 9 that holds out against the sealing hydraulic fluid port by spring 7, be provided with the valve 10 that holds out against the sealing hydraulic fluid port by spring 11 in the following main body 12, after the dismounting, upper and lower main body by valve (9,10) sealing hydraulic fluid port, guarantees that fluid can not flow out or ooze respectively, during butt joint, upper and lower valve body is connected inserting; Make 10 pairs of tops of valve 9 and valve, open hydraulic fluid port, the fluid in the valve can free flow.For solving the problem of oil pipe dish hinge, on last main body 1, have annular groove, make positioning ball 14 fall into groove after, last main body 1 can be followed the oil pipe rotation, can not cut with scissors phenomenon by the generation dish.
The utility model has the advantages that to pull out to connect conveniently, stream oil, oil dripping and dish hinge phenomenon can not occur, easy to use.
Accompanying drawing is embodiment of the present utility model:
Accompanying drawing 1 is first kind of example structure schematic representation of the present utility model.
Accompanying drawing 2 is second kind of example structure schematic representation of the present utility model.
Accompanying drawing 3 is the third example structure schematic representation of the present utility model.
The utility model includes main body 1, following main body 12, overcoat 5 and spring 6, in last main body 1, regulate the spring 7 of elastic force size by adjusted nail 2, the valve 9 of sealing hydraulic fluid port is an end that withstands on spring 7, adjusted nail 2 has endoporus, high pressure oil charges in the main body 1 from endoporus, sealed by valve 9, have annular groove in last main body 1 and positioning bead 14 position that adapts.
Have in the following main body 12 by regulating nail 13 down and regulate the spring 11 of elastic force size, the valve 10 of sealing hydraulic fluid port is an end that withstands on spring 11, and following adjusting nail 13 has endoporus, and fluid charges into down in the main body 12 from endoporus, is enclosed in down in the main body 12 by valve 10.It is fastening to block pearl cover 3 and following main body 12, and two positioning balls 14 are placed in the card pearl cover 3, are entangled by overcoat 5, and overcoat 5 is to push the right to by the elastic force of spring 6, is provided with seal ring 8 in following main body 12 with last main body 1 joint.
When upper and lower main body connects, pulling overcoat 5 is to moving to left earlier, the hydraulic fluid port external diameter of last main body 1 is inserted seal ring 8 internal diameters, loose one's grip after positioning ball 14 falls into annular groove on the main body 1 determining, overcoat 5 moves to right under the elastic force effect of spring 6, positioning ball 14 is pressed in the groove locatees, at this moment, because valve 9 and 10 pairs of tops of valve are opened former each self-enclosed hydraulic fluid port, make high pressure oil to flow through smoothly.Simultaneously because positioning ball 14 falls in the annular groove, make upper and lower main body (1,12) connect fastening after, can rotate mutually.During dismounting, pulling overcoat 5 is to moving to left, and outwards main body 1 is gone up in pulling, and positioning ball 14 is skidded off in annular groove, upper and lower body portion from, valve 9 and valve 10 be hydraulic fluid port sealing separately under the elastic force effect.
Take such scheme, the utility model has three kinds of embodiments, embodiment one as shown in Figure 1, the valve 9 of main body 1 hydraulic fluid port is to adopt steel ball in the sealing, the sealing valve 10 of main body 12 hydraulic fluid ports down is to adopt the top plug, during butt joint, the top plug backs down steel ball, and oil circuit is connected, and embodiment two as shown in Figure 2, the valve 9 of main body 1 hydraulic fluid port is to adopt steel ball in the sealing, the sealing valve of main body 12 hydraulic fluid ports down is to adopt steel ball, and during butt joint, two steel balls are to the top, oil circuit is connected, embodiment three as shown in Figure 2, the valve 9 of main body 1 oil is to adopt the top plug in the sealing, the sealing valve 10 of main body 12 hydraulic fluid ports down is to adopt the top plug, when two top plugs join to the top, oil circuit is connected.
In the accompanying drawing, the 2nd, jump ring.
