Abstract
The utility model discloses a kind of self-inspection Petroleum screen tube, comprise the tube connector that screen body is connected with respectively at described screen body two ends, described screen body lumenal cross-section is rectangle, axially extended demarcation strip is provided with in the middle part of its inner chamber, described demarcation strip both sides are respectively first runner in left side and second runner on right side, the vertical strip screen cloth socket extended all is had in the middle part of the both sides sidewall of described screen body, screen cloth is arranged in screen frame, two described screen frames coordinate between screen cloth socket described with two respectively and seal, two described screen clothes lay respectively in described first runner and described second runner, the side that the liquid of the described screen cloth in described first runner flows into is provided with valve.A kind of self-inspection Petroleum screen tube of the utility model, can judge whether screen casing blocks intuitively, and also without the need to blinding off a line during cleaning screen casing, still can normally produce when making cleaning or change screen cloth.
Description
Technical field
The utility model relates to OCTG manufacturing technology field, especially a kind of self-inspection Petroleum screen tube.
Background technology
Existing Petroleum screen tube is difficult to find out whether block intuitively usually, screen casing must be pulled down and just can judge, and dismantles the necessary closing duct of screen casing, and this occurs again the problem that cannot normally produce.
Utility model content
The utility model, for the deficiencies in the prior art, proposes a kind of self-inspection Petroleum screen tube, can judge whether screen casing blocks intuitively, and also without the need to blinding off a line during cleaning screen casing, still can normally produce when making cleaning or change screen cloth.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme:
A kind of self-inspection Petroleum screen tube, comprises the tube connector that screen body is connected with respectively at described screen body two ends,
Described screen body lumenal cross-section is rectangle, is provided with axially extended demarcation strip in the middle part of its inner chamber, and described demarcation strip both sides are respectively first runner in left side and second runner on right side,
The vertical strip screen cloth socket extended all is had in the middle part of the both sides sidewall of described screen body, screen cloth is arranged in screen frame, two described screen frames coordinate between screen cloth socket described with two respectively and seal, two described screen clothes lay respectively in described first runner and described second runner
The side that the liquid of the described screen cloth in described first runner flows into is provided with valve,
The side that the liquid of the described screen cloth in described second runner flows into is provided with damping seal door, and it is hinged that described damping seal door one end and described second runner inwall pass through damping spring,
The opposite side of the described screen cloth in described second runner is provided with flow meter.
Further, described damping seal door and described second runner seal.
A kind of self-inspection Petroleum screen tube of the utility model, can judge whether screen casing blocks intuitively, and also without the need to blinding off a line during cleaning screen casing, still can normally produce when making cleaning or change screen cloth.
Accompanying drawing explanation
Fig. 1 is the schematic top plan view of a kind of self-inspection Petroleum screen tube described in the utility model.
Detailed description of the invention
Be described in detail the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of self-inspection Petroleum screen tube as shown in Figure 1, comprises the tube connector 2 that screen body 1 is connected with respectively at screen body 1 two ends,
Screen body 1 lumenal cross-section is rectangle, is provided with axially extended demarcation strip 11 in the middle part of its inner chamber, and demarcation strip 11 both sides are respectively first runner 9 in left side and second runner 10 on right side,
The vertical strip screen cloth socket extended all is had in the middle part of the both sides sidewall of screen body 1, screen cloth 3 is arranged in screen frame, two screen frames respectively with coordinate between two screen cloth sockets and seal, two screen clothes 3 lay respectively in the first runner 9 and the second runner 10
The side that the liquid of the screen cloth 3 in the first runner 9 flows into is provided with valve 6,
The side that the liquid of the screen cloth 3 in the second runner 10 flows into is provided with damping seal door 7, and it is hinged that damping seal door 7 one end and the second runner 10 inwall pass through damping spring,
The opposite side of the screen cloth 3 in the second runner 10 is provided with flow meter 8.
Damping seal door 7 and the second runner 10 seal.
During use, connected respectively at both sides petroleum pipeline by two tube connectors 2, valve 6 is opened, liquid is by the first runner 9, due to the effect of the damping spring of damping seal door 7 in the second runner 10, fluid pressure is less than the elastic force of damping spring, and liquid cannot pass through the second runner 10.When the screen cloth 3 in the first runner 9 blocks gradually due to impurity, the fluid pressure at damping seal door 7 place increases gradually, until when fluid pressure is more than or equal to damping spring elastic force, damping seal door 7 is opened, by the second runner 10, in flow meter 8, there is flow velocity registration in liquid.Now valve-off 6, cleans the screen cloth 3 in the first runner 9.
A kind of self-inspection Petroleum screen tube of the utility model, can judge whether screen casing blocks intuitively, and also without the need to blinding off a line during cleaning screen casing, still can normally produce when making cleaning or change screen cloth.
