Specifically, pipeline is switched to when fluid is flowed out by third chamber in pipeline, i.e., flow direction is current stabilization mistake
Filter-first chamber-second chamber-third chamber is major cycle, and when by being flowed out by the 4th chamber, i.e., path direction is steady
Four chamber of flow filter-first chamber-the recycles for side.It is first when output turn the 4th chamber output of third chamber is in the milk
The first current limliting pipeline of first throttle valve is first flowed through, the first current limliting pipeline is under spring and Fluid pressure effect so that passes through section
The fluid of through-hole, which can not continue to flow into, on flow table eliminates water attack effect mechanism pipeline, can only be flowed by the first current limliting pipeline
Into water attack effect mechanism pipeline is eliminated, throttling action is realized, when then flowing through the second current limliting pipeline of second throttle, continue
Throttling is generated, by throttling process twice, meets petroleum drilling operation major cycle and changes one's position that pregrouting amount needed for cycle is small, discharge capacity is small
Requirement.
By the 4th chamber output turn third chamber output be in the milk when, first flow through the second current limiting tube of second throttle
Road, the second choke manifold plays throttling action, and when then flowing through the first current limliting pipeline of first throttle valve, fluid flow pressure pushes
First current limliting pipeline moves, and the movement of the first current limliting pipeline makes spring compression compression, and flow channel expands at this time, and fluid not only passes through
First current limliting pipeline flows, and also eliminates water attack effect mechanism by the through-hole outflow on throttling plate, at this time the first current limliting pipeline base
This does not play throttling action, meets petroleum drilling operation side cycle and turns the requirement that required pregrouting amount is big, discharge capacity is big when major cycle.
Further, referring to Fig. 1, in the present invention, connect on the connecting line of the third chamber and the 4th chamber
It is connected to bypass relief pipeline 180.Either major cycle change one's position cycle or side cycle turn major cycle during, complete manage
It after the handoff procedure on road, is required for carrying out pressure release to original pipeline, to prepare for pipeline switching next time, preferably
, in the present embodiment, there are two switching valves, the bypass to let out for setting in the connecting pipe of the third chamber and the 4th chamber
Pressure pipeline is connected between the switching valve, is realized to corresponding major cycle and side cycle by opening and closing corresponding switching valve
Switching pressure release.
Further, referring to Fig. 3 and Fig. 4, the junction of the bypass line and first throttle valve and second throttle is set
It is equipped with 200 dual-seal of metal sealing 190 and rubber seal.When fluid stream is through throttle valve, due to the throttling action of throttle valve,
Be easy to generate throttle valve larger impact, so as to cause the damage of throttle valve, impact in order to prevent influence to throttle valve and
The service life for improving throttle valve is provided with metal sealing and rubber in the junction of bypass line and first throttle valve and second throttle
Glue seals dual-seal.
