[0002] After the oil screen has been used for a period of time, the impurities in the oil will be deposited on the screen, and the screen needs to be replaced. The existing screen needs to temporarily cut off the channel of the oil pipeline when the screen is replaced, which reduces production. At the same time, the existing screen can only remove the impurities on the screen, but the impurities deposited in the screen on one side of the screen cannot be removed, resulting in many remaining impurities in the screen, which affects the quality of oil. In addition, the existing When the screen is inserted into the screen, there will be a gap with the screen, and some gaskets are set between the screen and the screen. Most of these are fixed gaskets, which have poor sealing effect, inconvenient insertion, and troublesome use.

The invention discloses a petroleum screen pipe. The petroleum screen pipe comprises a screen pipe body, a petroleum inlet arranged in the left side of the screen pipe body and a petroleum outlet arranged in the right side of the screen pipe body. A valve body is arranged on the left side of the screen pipe body. A ball is rotationally arranged in the valve body. A first connection channel, a second connection channel and a third connection channel are arranged inside the ball. One end of the first connection channel communicates with the second connection channel and the third connection channel. The other end of the first connection channel communicates with the petroleum inlet. An upper channel is arranged at the upper end of the screen pipe body. One end of the upper channel communicates with the petroleum outlet. The other end of the upper channel communicates with the second connection channel. A lower channel is arranged at the lower end of the screen pipe body. One end of the lower channel communicates with the petroleum outlet. The other end of the lower channel communicates with the third connection channel.
Description
technical field [0001] The invention relates to petroleum equipment, in particular to a petroleum screen. Background technique [0002] After the oil screen has been used for a period of time, the impurities in the oil will be deposited on the screen, and the screen needs to be replaced. The existing screen needs to temporarily cut off the channel of the oil pipeline when the screen is replaced, which reduces production. At the same time, the existing screen can only remove the impurities on the screen, but the impurities deposited in the screen on one side of the screen cannot be removed, resulting in many remaining impurities remaining in the screen, affecting the quality of oil. In addition, the existing When the screen is inserted into the screen, there will be a gap between the screen and the screen, and some gaskets are provided between the screen and the screen. Most of these are fixed gaskets, which have poor sealing effect, are inconvenient to insert, and are troubl...
