Abstract
The utility model provides an anti-blocking one-way watering valve and aims at overcoming the shortcoming that an existing one-way watering valve is easily blocked and enables the wall flushing operation not be normally performed. An upper connector, a valve body and a lower connector of the anti-blocking one-way watering valve are sequentially and fixedly connected from top to bottom, and the pipe wall of the valve body is provided with a radial liquid outlet hole. A valve seat is installed at the upper-end portion of a valve body inner hole and axially fixed through a pipe plug, and the pipe plug is located at the upper end of the valve seat and fixedly connected with the valve body. A valve ball and a centralizing rod are installed between the valve seat and the lower connector from top to bottom, and the lower-end portion of the centralizing rod is inserted into an axial through hole of the lower connector. A spring installed in the axial direction of the centralizing rod and located between the middle of the centralizing rod and the lower connector. The anti-blocking one-way watering valve has the advantages of being simple in structure, convenient to operate, capable of achieving the well flushing operation with stop, solving the problem that the one-way watering valve is blocked in the oil extraction process when a heat carrier is filled into a hollow sucker rod, achieving direct circulating well flushing in an oil pipe, improving crude oil temperature, reducing the crude oil viscosity and preventing paraffin precipitation in the oil pipe.
Description
Technical field
The utility model relates to a kind of water doping valve of hollow rod injection heat transfer medium extracting device of oil, especially relates to a kind of anti-blocking one-way watering valve.
Background technology
In order to be satisfied with the demand of paraffin removal of pumping well viscosity reduction, to develop hollow rod and injected heat transfer medium extracting device of oil.This device is in pit shaft oil pipe, to form a direct circulation system, in pit shaft, inject heat transfer medium (hot water, deep fat) or chemical agent by the inner chamber of hollow rod with continuous or discontinuous manner, heat transfer medium or chemical agent are through hollow rod bottom one-way watering valve, return out from the annular space of R a T, thereby reach raising temperature in wellbore, reduce viscosity of crude, eliminate the object of wax deposition, maintain oil well and normally produce.The feature of this endless form is, do not stopping can to carry out at any time as required clean-out service under well condition, and technique is simple, the thermal efficiency is high, flushing fluid consumption is few, cost is low, and flushing fluid do not go out by deep well pump, can not reduce rate while oil recovery; Meanwhile, because flushing fluid does not contact with oil reservoir, avoid causing the injury to oil reservoir.
One-way watering valve is to ensure that hollow rod injects the core component of the normal operation of heat transfer medium device.At present, water doping valve is to be connected and composed successively from top to bottom by top connection, suspension body, valve body, valve seat jackscrew and lower contact, make injection pressure higher because area of passage is little, again often there is water doping valve clogging when well-flushing, limited hollow rod and injected applying of heat transfer medium extracting device of oil.
Utility model content
The easy obstruction existing in order to overcome existing one-way watering valve, the deficiency that causes clean-out service normally not carry out, the utility model provides a kind of anti-blocking one-way watering valve.
The utility model solves the technical scheme that its technical problem adopts: anti-blocking one-way watering valve comprises top connection, lower contact, valve body, valve seat, valve ball, top connection, valve body, lower contact are from top to bottom fixedly connected sequentially, and have radially fluid hole on the tube wall of valve body.The upper end of valve body inner bore is provided with valve seat, and valve seat is by pipe close axial restraint, and pipe close is positioned at the upper end of valve seat and is fixedly connected with valve body.Valve ball, righting rod are from top to bottom installed between valve seat and lower contact; Insert in the axially extending bore of lower contact the bottom of righting rod, moves up and down along the axially extending bore of lower contact; Righting rod is up big and down small multidiameter, righting rod be axially installed with spring, spring is between righting rod middle part and lower contact.
The beneficial effects of the utility model are, simple in structure, handled easily, can realize and not stop well clean-out service, solve hollow rod and inject heat transfer medium oil recovery process one-way watering valve blockage problem, realized the direct flushing in oil pipe, improve crude oil temperature, reduce viscosity of crude, prevent wax deposition in oil pipe.
Brief description of the drawings
Fig. 1 is the structural representation of the anti-blocking one-way watering valve of the utility model.
In figure: 1. top connection, 2. pipe close, 3. valve seat, 4. valve ball, 5. valve body, 6. righting rod, 7. spring, 8. lower contact, 9. fluid hole radially.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.But those skilled in the art should know, the invention is not restricted to listed detailed description of the invention, as long as spirit according to the invention all should be included in protection scope of the present invention.
Referring to accompanying drawing 1.The anti-blocking one-way watering valve of the utility model comprises top connection 1, lower contact 8, valve body 5, valve seat 3, valve ball 4, top connection 1, valve body 5, lower contact 8 are from top to bottom fixedly connected sequentially, on the tube wall of valve body 5, there is radially fluid hole 9, along valve body 5 axially have radially fluid holes 9 more than 2 rows, every row has 2 or 2 above radially fluid holes 9 along the circumference uniform distribution of valve body 5.
The endoporus of valve body 5 is up/down perforation, and the upper end of endoporus is provided with valve seat 3, and valve seat 3 is by pipe close 2 axial restraints, and pipe close 2 is positioned at the upper end of valve seat 3 and is fixedly connected with valve body 5.
Valve ball 4, righting rod 6 are from top to bottom installed between valve seat 3 and lower contact 8, and insert in the axially extending bore of lower contact 8 bottom of righting rod 6, and the bottom of righting rod 6 can move axially along the hole of lower contact 8.
Righting rod 6 is up big and down small multidiameter, and upper surface is cambered surface, and the radian of cambered surface is slightly larger than valve ball 4.Righting rod 6 middle parts are axially installed with spring 7, and spring 7 is between the middle part and lower contact of righting rod 6.
The operating principle of the anti-blocking one-way watering valve of the utility model is: in hollow rod, inject heat transfer medium, injection pressure is higher than in the oil pipe of water doping valve bottom when head of liquid, under the effect of inside and outside differential pressure, the resistance that promotion valve ball 4 overcomes spring 7 moves down, water doping valve is opened, heat transfer medium enters the inner chamber of valve body 5, then enters in the annular space of sucker rod and oil pipe by fluid hole 9 radially, mixes and be lifted to ground with crude oil.While stopping noting, spring 7 is replied promotion valve ball and is upwards closed water doping valve.
The anti-blocking one-way watering valve of the utility model is the supporting technology that hollow rod injects heat transfer medium device, can regularly heat according to wax period paraffin-troubled well, can based on crude viscosity carry out laser heating to viscosity reduction well, effectively solves high sticky, wax deposition problem.
It should be noted that above-described embodiment is example and unrestricted the present invention, those skilled in the art can design a lot of alternate embodiments and not depart from the claim scope of this patent.
