Specific embodiment
The present invention provides a kind of low sheraing pressure regulation Injecting polymer units, and package unit is compact-sized, are easily installed, and adjust spirit
It is living, guarantee that viscosity hardly declines while realizing decompression, fully meets oil field tertiary process and infuse poly- requirement in the process.
The present invention is described in detail with specific embodiment with reference to the accompanying drawings of the specification.
As shown in Figure 1, a kind of low sheraing pressure regulation Injecting polymer unit provided by the invention, including shell 10, it is equipped in shell 10:
Switching valve 20, spiral pipeline 30 and flusher.
Switching valve 20 at least two is respectively equipped with feeding opening 201 and medicine outlet 202.For the inlet and outlet of polymer.
Spiral pipeline 30, at least one, both ends are respectively equipped with import 31 and outlet 32, import 31 and export 32 respectively with adjacent two
A switching valve 20 connects, and polymer flow is through spiral pipeline 30.
Flusher, including flushing water inlet pipe 41 and flushing water outlet pipe 42, respectively and along the front-end and back-end of flow direction
Two switching valves 20 connection.Flusher prevents from repeatedly infusing poly- caused device for washing conversion valve 20, spiral pipeline 30
Blocking.
In spiral pipeline 30 flow direction of fluid be from top to bottom, flowing of the polymer in spiral pipeline 30 realize decompression and
30 more antihypertensive effects of number of spiral pipeline are more obvious.
The upper inner of shell 10 is equipped with the horizontal support 11 of bar shaped, is used for fixed conversion valve, and switching valve 20 is successively set
It sets upper, is set as sustained height, the side of switching valve 20 is arranged in feeding opening 201 and medicine outlet 202.Polymer horizontally enters into
Level outflow.
The bottom of spiral pipeline 30 is fixed on the bottom surface of shell 10, guarantees polymer smooth flow in spiral pipeline 30,
It prevents from causing the flexible of spiral pipeline 30 due to pressure difference.It is concordant with feeding opening 201 or medicine outlet 202 at top, guarantee polymer
Flow in and out the steady of state.
Shell 10 is equipped with horizontal drug-feeding tube 203 and drug discharging tube 204, the switching valve of drug-feeding tube 203 and front end into medicine
Mouth 201 connects, and drug discharging tube 204 is connect with the medicine outlet 202 of the switching valve of rear end.42 edge of flushing water inlet pipe 41 and flushing water outlet pipe
Horizontal direction protrudes into shell 10, and water inlet is facilitated to rinse.
