Abstract
The utility model relates to a side direction type oil inlet valve for oil pumps, which is used for oil production in oil fields and is composed of a pump barrel connecting tube, a valve block, a by-pass connecting head and a tail tube, wherein the pump barrel connecting tube is connected with the upper part of the by-pass connecting head through a big thread, the valve block is connected with the upper part of the by-pass connecting head through small threads, the lower part of the by-pass connecting head is connected with the tail tube, and the lower part of the tail tube is sealed. The by-pass connecting head comprises a side oil inlet passage and an inner sand settling and pressure transmitting passage. Raw oil enters from the side oil inlet passage of the by-pass connecting head, flows upwards through the valve block and is pumped out by a pump. When sand and foreign matter exist on the valve block, the sand and the foreign matter settle down into the tail tube through the annular space of the valve block and the pump barrel connecting tube and then through the sand settling and pressure transmitting passage of the by-pass connecting head. The valve block can not be buried by sand, and oil inlet and outlet passages are clear all the time. The repair free period of an oil well is long. The upper parts of the tail tube and the valve block are communicated by the sand settling and pressure transmitting passage with pressure capable of being transmitted, so that a hydraulic oil tube anchor can be installed between the by-pass connecting head and the tail tube. As a result, not only can the crawl of oil pumping tube columns can be prevented, but also the bending and wearing problems of the tube columns can not occur.
Description
One, technical field
The utility model is the side direction type oil-well pump oil inlet valve that a kind of oil field machinery oil is used.
Two, background technique
Present oil-well pump oil inlet valve is a straight-through type, in the bottom of oiling valve hydraulic type oil pipe anchor can not be installed, mechanical type oil pipe anchor can only be installed, and mechanical type oil pipe anchor causes tubing bending on the pump easily, fuel-displaced rod tube wear problem, when straight-through type oiling valve top deposits a small amount of sand or foreign material, will blocking channel and cause not oil-feed, oil well is stopped production change pump, lose serious through damaging due to crushing.
Three, summary of the invention
The purpose of this utility model is a kind of side direction type oil-well pump oil inlet valve of design, by changing runner it is not buried by sand, and hydraulic type oil pipe anchor can be installed under pump.
The purpose of this utility model is achieved in that it is made up of pump barrel connecting tube, valve group, by-pass connection, tail pipe.Pump barrel connecting tube bottom connects with by-pass connection top major thread, and the valve group connects with by-pass connection top minor thread, and the by-pass connection bottom connects with tail pipe top, and the tail pipe bottom is airtight.By-pass connection has two passages, and one is the side direction oil inlet passage, and one is inner sand setting pressure transmission passage.In oil well pump when oil pumping,, crude oil enters from by-pass connection side direction oil inlet passage, through the valve group in go up to flow and be pumped out, when on the valve group sand and foreign material being arranged, sand and foreign material are to sinking, and through the annular space of valve group and pump barrel connecting tube, the sand setting pressure transmission passage through by-pass connection sinks in the tail pipe again.Hydraulic type oil pipe anchor can transmit pressure by sand setting pressure transmission passage UNICOM on tail pipe and the valve group, so can be installed between by-pass connection and tail pipe.
The beneficial effects of the utility model are: newly-designed side direction type oil-well pump oil inlet valve can reach purpose of design, after sand sinks to the bottom tail pipe, the valve group can not buried by sand, and advancing oil drain passage is unimpeded all the time, and oil well repair free period is long, do not stop production, because pressure can reach in the tail pipe of bottom, so, hydraulic type oil pipe anchor can be installed under pump, both prevent the oil pump tubular column wriggling, and the drilling pipe bending wear problem can not occur again.
Four, description of drawings
Accompanying drawing is a side direction type oil-well pump oil inlet valve embodiment erection drawing.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As shown in the figure, the 1st, pump barrel connecting tube, the 2nd, valve group, the 3rd, by-pass connection, the 4th, tail pipe.Be that the utility model is made up of pump barrel connecting tube 1, valve group 2, by-pass connection 3, tail pipe 4.Pump barrel connecting tube 1 bottom connects with by-pass connection 3 top major threads, and valve group 2 connects with by-pass connection 3 top minor threads, and by-pass connection 3 bottoms connect with tail pipe 4 tops, and tail pipe 4 bottoms are airtight.By-pass connection 3 has two passages, and one is side direction oil inlet passage A, and one is inner sand setting pressure transmission channel B.During the oil well pump oil pumping, crude oil enters from by-pass connection 3 side direction oil inlet passage A, through valve group 2 in go up to flow and to be pumped out, when on the valve group 2 sand and foreign material being arranged, sand and foreign material are to sinking, through the annular space of valve group 2 with pump barrel connecting tube 1, the sand setting pressure transmission channel B through by-pass connection 3 sinks in the tail pipe 4 again.Can transmit pressure by sand setting pressure transmission channel B UNICOM on tail pipe 4 and the valve group 2, so between by-pass connection 3 and tail pipe 4, hydraulic type oil pipe anchor can be installed.
