Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Laddering oil separator as described in Fig. 1 and Fig. 3, comprise valve body 1, multiple valve pocket 2 is provided with in valve body 1, slidably spool 3 is provided with in valve pocket 2, particularly, valve pocket can be arranged in parallel, also can angledly arrange, spool 3 can comprise three spools, 3, three spools 3 and be arranged in parallel, and be communicated with by oil duct 4 between each spool 3, meanwhile, valve body 1 also slides and is provided with pushing mechanism, pushing mechanism is specifically positioned at the end of spool 3, and the inner of pushing mechanism is stretched in valve pocket 2, valve body 1 is stretched out in the outer end of pushing mechanism.Like this, by arranging pushing mechanism on valve body 1, when pushing mechanism moves, movable valve plug 3 can be with to move, thus preferably resolve and cause the out-of-work problem of laddering oil separator because of certain spool jams, there is fault and easily get rid of, the advantage that lubricating efficiency is high.
In such scheme, preferably, the end of valve pocket 2 is provided with the plug 5 for closeding valve cavity 2, and pushing mechanism is arranged on plug 5, owing to arranging plug 3, can facilitate the processing of valve pocket 2 and the installation of pushing mechanism.Particularly, the modes such as plug 5 can be threaded connection, welding are arranged on valve body 1, also can be one-body molded with valve body 1, as long as can play the effect of shutoff valve pocket 2.
In such scheme, pushing mechanism can adopt various structures, and in the concrete mode of one, as shown in Figure 1, pushing mechanism comprises the push rod 6 sliding and be arranged on plug 5, and the inner of push rod 6 is fixed on the end of spool 3, and described valve body 1 is stretched out in the outer end of push rod 6.Due to the inner fixed spool 3 of push rod 6, therefore, spool 3 can be promoted by push rod 6 and move left and right, discharge the plugging fault of spool 3 fast.
In the concrete mode of another kind, as shown in Figure 2, pushing mechanism is piston with rod 7, the two ends of spool 3 are respectively equipped with piston with rod 7, piston with rod 7 comprises the piston 71 being positioned at valve pocket 2 and the piston rod 72 be arranged on plug 5, the inner of piston rod 72 is fixedly connected with piston 71, and valve body 1 is stretched out in its outer end.Spool 3 comprises the first spool and the second spool, when blocking occurs spool 3, promotes the piston with rod 7 of the left and right sides by external force, drives the first spool to move left and right further, thus solves the blockage problem of a certain spool.In the technical program, it should be noted that, only can arrange a piston with rod 7 at the left end of spool 3 or right-hand member, technique effect and the efficiency of just getting rid of blocking all arrange piston with rod 7 not as good as two ends.
As shown in Figure 3, for accurately judging the position of spool 3, so that accurately use pushing mechanism, piston with rod 7 is provided with through hole vertically, the end winding support of spool 3 is provided with indicating arm 8, indicating arm 8 slides and is arranged in aforementioned through-hole, piston with rod 7 is stretched out in the outer end of indicating arm 8, by being fixed on the indicating arm 8 on spool 3, accurately can judging the position of spool 3, it should be noted that, indicating arm 8 can be arranged on the one or both ends of spool 3, can be arranged on certain spool 3, also all can arrange on each spool 3, select as required.
In technique scheme, further, be Leakage prevention, between piston 71 and valve pocket 6, be also provided with Sealing, and/or, be provided with Sealing between the through hole of indicating arm 8 and piston with rod 7.Particularly, can be provided with seal groove on the through hole of piston 71 end and/or piston with rod 7, be provided with Sealing in seal groove, Sealing can be seal ring, and its quantity can be one or more.
For indicating arm 8 and spool 3, in one embodiment, for convenience of dismounting, indicating arm 8 is removably fixedly installed on the end of spool 3, specifically can arrange outside thread on indicating arm 8, offer the inner bolt hole coordinated with outside thread in spool 3, certainly, can also be arranged by alternate manner, as one-body molded, welding, specifically can arrange as required.
In such scheme, pushing mechanism can be arranged on the one or both ends of spool 3, and preferably, the two ends of spool 3 are provided with pushing mechanism, are provided with Sealing between pushing mechanism and valve body 1.The efficiency that pushing mechanism is fixed a breakdown and the sealing being conducive to ensureing valve pocket 2 can be improved like this.
In such scheme, particularly, as shown in Figure 1 to Figure 3, spool 5 preferably include connect successively first paragraph, second segment, the 3rd section, the 4th section and the 5th section, first paragraph, the 3rd section and the 5th section are slidably matched with valve pocket 6, and the diameter of second segment and the 4th section is less than the diameter of described first paragraph, the 3rd section and the 5th section.
The laddering oil separator of said structure, when the first spool jams, promote the pushing mechanism of the first spool end by external force, when pushing mechanism moves, movable valve plug 3 can be with to move, thus solution cause the out-of-work problem of laddering oil separator because spool 3 blocks preferably.Compared with existing laddering oil separator, there is the advantage that fault is easily got rid of, lubricating efficiency is high.
Meanwhile, the utility model also proposes a kind of lubrication system, comprises lubricant pump and laddering oil separator, the entrance of lubricant pump is communicated with lubricant medium source, the entrance of the laddering oil separator of outlet of lubricant pump, particularly, laddering oil separator is laddering oil separator as above.
Finally, the utility model also proposes a kind of concrete pumping equipment, comprises laddering oil separator as above or lubrication system as above.
Correspondingly, above-mentioned lubrication system and concrete pumping equipment also have the advantage that fault is easily got rid of, lubricating efficiency is high.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
