After pump, the sealing of ball-and-seat is more beneficial for, prevents oily liquid in pipe from flowing back by submersible electric pump.Set in the discharge opeing cavity shell 6
Apocenosis passage is put, apocenosis passage one end connects with the port of export of production passage in single current valve chest 1, and the other end connects with oil jacket annular space
Logical, being provided with the apocenosis passage can move to open or close the discharge opeing valve ball 4 of apocenosis passage, when the valve with valve plate 8
During the closing production passage of plate 8, the discharge opeing valve ball 4 opens the apocenosis passage, when the valve plate 8 opens production passage, institute
State discharge opeing valve ball 4 and close the apocenosis passage.
The valve plate 8 is hinged on single current valve chest 1 by disc support axle 11, and the rear end of valve plate 8 is provided with valve handle, described
Discharge opeing valve ball 4 is connected with apocenosis passage valve rod 7, and described apocenosis passage valve rod 7 is located inside discharge opeing cavity shell 6, with exhaust chamber
The hole slot opened up inside housing 6 is engaged, it is ensured that what discharge opeing valve ball 4 moved up and down stablizes.With discharge opeing above the valve handle
The lower end of passage valve rod 7 abuts, and being provided between the discharge opeing cavity shell 6 and discharge opeing valve ball 4 makes discharge opeing valve ball 4 lead to closing discharge opeing
The spring 3 of road direction motion.Described valve plate 8 has a longer valve handle, and valve plate 8 can be around disc support axle 11 in 90 degree of models
Interior rotation is enclosed, apocenosis passage valve rod 7 can be realized moving up and down under the collective effect of the valve handle of valve plate 8 and spring 3, so as to band
Dynamic discharge opeing valve ball 4 is moved up and down in discharge opeing cavity shell 6.In actual applications, the described bottom of discharge opeing cavity shell 6 be valve ball with
Valve plate linkage chamber 9, valve ball can prevent oily tube fluid from flowing into oil jacket ring by the position of disc support axle with valve plate linkage chamber 9
Sky, while not affecting valve plate 8 to drive the up and down motion of apocenosis passage valve rod 7.
The top surface of discharge opeing valve ball 4 is provided with the concave structure for placing the lower end of spring 3, and concave structure can prevent spring
3 there is skew back, play a part of fixed spring 3.The top of the discharge opeing cavity shell 6 has been bolted apocenosis passage end cap 2,
The upper end of spring 3 is withstood on below apocenosis passage end cap 2.Apocenosis passage end cap 2 be disposed to install spring 3, discharge opeing valve ball 4
With the convenience of the grade of apocenosis passage valve rod 7.
The inner chamber of the apocenosis passage integrally in cylinder, inner chamber bottom by two outages 5 respectively with production passage
The port of export connect with oil jacket annular space, discharge opeing valve ball 4 is engaged with the internal diameter of inner chamber, can prevent well liquid pass through discharge opeing valve ball 4

Ensure that described discharge opeing valve ball 4 will not block all the time apocenosis passage relief hole 10 as far as possible.
During utility model works, the ball-and-seat of submerged electric oil pump well is arranged in the flow string of submerged electric oil pump well, is dived
When oily electric pump well is normally produced, in the presence of submersible electric pump goes out oral fluid stream, valve plate 8 is in opening, and the valve handle of valve plate 8 is not
The active force for applying upwards to apocenosis passage valve rod 7 again, discharge opeing valve ball 4 is moved down in the presence of spring 3, and blocking discharge opeing is led to
Road outage 5, makes oil pipe inside not connect with oil jacket annular space, it is ensured that the normal production of submerged electric oil pump well.Submersible electric pump termination of pumping
Afterwards, valve plate 8 is closed under liquid gravity effect in oil pipe, meanwhile, the valve handle of valve plate 8 drives apocenosis passage valve rod 7 and tapping valve
Ball 4 is moved upwards, and apocenosis passage outage 5 is no longer blocked by discharge opeing valve ball 4, realizes the connection between oil pipe and oil jacket annular space,
So well liquid flows under the influence of gravity into oil jacket annular space in oil pipe, will not apply reactive torque to shaft of electrical submersible pump, for quiet
The relatively low oil well of liquid level, without the need for carrying out crude oil in oil pipe replacement, can save man power and material's cost, for the oil of high hydrostatic level
Well, can adopt the method displacement crude oil in oil pipe for just squeezing diesel oil, during using positive squeezing, it is no longer necessary to which steel wire operation opens oil well
Circulation slide sleeve set up circulation canal, can effectively save operating cost, shorten the activity duration.
Many details are elaborated in above description in order to fully understand this utility model, but, this practicality is new
Type can also be different from other modes described here to implement using other, it is thus impossible to be interpreted as protecting this utility model
The restriction of shield scope.
