Technical Field

The invention relates to the technical field of oil drains, in particular to a variable-pressure oil pipe oil drain.

Background

The oil drainer is a tool matched with an oil well pump for use, when oil pumping operation is carried out, an oil pipe and a sleeve are communicated, crude oil in the oil pipe is discharged into a well, so that the purposes of oil drainage and pressure reduction are achieved, crude oil is not retained in an lifted oil pipe column, the wellhead environment is improved, the pollution of crude oil, wax blocks, broken nylon blocks and other substances brought out of the well by the oil pipe to the ground layer by layer is avoided, and in addition, a large amount of water is required to be used for well washing in the cleaning process, so that manpower and material resources are wasted.

When the pressure that the bleeder received reaches the default, the stop gear of bleeder is destroyed, make the oil in the oil pipe can let out, the pressure default that changes the bleeder through the thickness that changes stop gear at present often, this operation is comparatively troublesome, need prepare the stop gear of different thinness to the pressure demand of difference, and traditional bleeder receives the oil pipe external pressure influence great, it is difficult control to let out pressure default, if improve on the basis based on current bleeder, research and development one kind does not receive the external pressure influence, the novel bleeder of the operating personnel of being convenient for adjustment bleeder pressure default will have positive meaning to the trade development.

Disclosure of Invention

The invention aims to provide a pressure-changing type oil pipe oil drainer to solve the problems that the existing oil drainer is greatly influenced by external pressure and the preset pressure value is not easy to adjust in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme that the device comprises a columnar body, a sliding block, a mounting plate and a plurality of limiting blocks, wherein a flow channel is arranged in the body along the length direction of the body, internal threads and external threads are respectively arranged at two ends of the body, a mounting block is arranged in the flow channel, the mounting block is provided with a cavity communicated with the outside, a first channel is arranged in the mounting block along the length direction of the body, a second channel which is vertical to and communicated with the first channel is arranged on the mounting block, the second channel is communicated with the outside of the body, the sliding block and the first channel form a moving pair, a through hole matched with the second channel is arranged on the sliding block, a plurality of clamping blocks are arranged at one side, close to the cavity, of the sliding block, the mounting plate is detachably mounted on the body, and the mounting, the mounting plate is further provided with an oil drainage hole matched with the second through hole, a plurality of mounting grooves are formed in the inner side of the mounting plate, one end of the limiting block abuts against the clamping block, and the other end of the limiting block is clamped in the mounting grooves.

Preferably, the mounting panel both ends all are equipped with the counter bore, the bolt install in the counter bore with body threaded connection realizes the mounting panel with the dismantlement of body is connected.

Preferably, the first passage extends through the mounting block.

Preferably, each of the latch blocks is equidistantly arranged on the sliding block.

Preferably, the slider is cylindrical.

Preferably, the limiting block is Y-shaped.

Preferably, the fixture block is in a triangular prism shape.

Preferably, the mounting block and the flow channel are of an integrated structure.

From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

according to the variable-pressure oil pipe bleeder provided by the invention, when the pressure applied to the top surface of the sliding block reaches a preset value, the limiting block is broken at the moment and is collected in the cavity, the sliding block moves downwards to enable the through hole to move to the position of the second channel, and at the moment, oil in the oil pipe can flow out through the oil drainage hole through the second channel, so that the purposes of oil drainage and pressure reduction are achieved;

an operator can also change the pressure preset value of the oil drain device according to requirements, disassemble the mounting plate detachably connected with the body, and then select a corresponding number of limiting blocks according to the pressure requirements, wherein one end of each limiting block is clamped in the mounting groove of the mounting plate, the other end of each limiting block abuts against the clamping block, the more the number of the limiting blocks is, the greater the pressure required for the sliding block to move downwards is, and the less the number of the limiting blocks is, the smaller the pressure required for the sliding block to move downwards is, so that the aim of changing the pressure preset value of the;

the maximum improvement point of the invention compared with the prior art is that the pressure preset value of the existing oil drain device can be influenced by the external pressure of the oil pipe, so that an operator can not accurately determine and change the pressure preset value of the oil drain device.

The pressure preset value of the oil drain device is not influenced by external pressure, so that an operator can conveniently adjust the pressure preset value of the oil drain device, the broken limiting blocks can be collected in the cavity, the oil well is not polluted, the practical significance and the popularization value are realized, and good economic benefits can be expected to be generated.
