Abstract
The utility model relates to a valve for washing. The utility model is composed of a valve body, a draw rod, plungers, a steel ball and a valve seat. The upper part of the draw rod is connected with a pump rod coupling and a back cap through a screw thread. A leather cup is arranged between a block ring and the back cap. The lower part of a valve port of the valve seat is provided with the steel ball and the plunger. The lower part of the edge of the valve seat is provided with a top sleeve, a top screw and the plunger, the lower part of which is provided with a pressure spring. The water consumption is less, and no water can leak towards a stratum.
Description
The utility model relates to a kind of Valve for washing, sticking cured usefulness in the scavenge pipe in recovering the oil in main fuel feeding field.Oil well production is after a period of time, and the borehole wall can bond cured, causes crude oil to flow out difficulty, causes oil well to stop up when serious.
Prior art constructions has only middle tube (with reference to figure 1), and backwashing manner is backwash.Hot water pours into downwards from well head, return through the valve body end opening, with reference to arrow dotted line 22 shown in Figure 1, return after arrow dotted line 23 instead on.Its deficiency is: moltenly in order not make water temperature fall the end do not change curedly, also must guarantee to have enough big hot water flow simultaneously, and sticking cured to rinse out, so the hot water consumption is big; Toward ground leak, cause formation contaminant and plug stifled easily, cause fuel-displaced not smooth.
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and provides a kind of water consumption the less and unlikely Valve for washing that causes toward ground leak.
The purpose of this utility model can reach by following measure.The utility model is made up of valve body, pull bar, plunger, steel ball and valve seat, pull bar top be threaded pump rod box cupling and back of the body cap, the back-up ring and the back of the body have leather cup between the cap, and steel ball and plunger are arranged under the valve seat valve port, top cover, jackscrew and plunger are arranged under the valve cup rim, and stage clip is arranged at the plunger bottom.
Between pull bar and the back-up ring, between plunger and the other tube and between valve seat and the other tube seal ring is arranged.
Fig. 1 is total figure that analyses and observe of the present utility model.
The representative of accompanying drawing piece number:
1, valve body 2, valve seat 3, seal ring 4, steel ball
5, top cover 6, jackscrew 7, plunger 8, seal ring
9, stage clip 10, plug 11, pump rod box cupling 12, pull bar
13, back of the body cap 14, leather cup 15, packing ring 16, back-up ring
17, seal ring 18, last aperture 19, following aperture 20, valve opening
21, by-pass port 22, arrow dotted line 23, arrow dotted line
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Fig. 1 represents structure of the present utility model, and usually, the utility model is loaded on the oil pipe (reach km deeply and more than the km), and valve body 1 has internal thread to be connected with oil pipe for the cylindrical body of the other tube of band above.Other tube upper and lower end has tube connection in last aperture 18 and following aperture 19 and the valve body, and the valve seat 2 of band seal ring 3 is arranged at other tube top, and steel ball 4 is arranged under the valve port of valve seat.Steel ball has 7 of the plungers of band seal ring 8 to head on, and top cover 5, jackscrew 6 and the supporting of plunger outer rim are arranged under the valve seat outer rim.Stage clip supporting is arranged under the plunger, plug 10 is arranged below the stage clip.
There is pull bar 12 in valve body central authorities, and pull bar top be threaded pump rod box cupling 11 and back of the body cap 13 have the back-up ring 16 of packing ring 15, leather cup 14 and band seal ring 17 under the back of the body cap, and the pull bar lower end is connected with pump (expression on the figure).
During use, earlier sucker rod is transferred, back-up ring 16 is sitting on the step of valve body, be fed into hot water from the oil pipe top and make leather cup 14 spreadings, cured melting away with the inner tube wall bonding, 18 steel ball depressed through last aperture through this valve and from bypass, side valve is opened, band La Shui discharges and returns recovery through valve opening 20 and by-pass port 21.
The utility model contrast prior art has the less and unlikely advantage that causes toward ground leak of water consumption.
