Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 1 and 2, an underwater chemical agent injection device includes a base 1, an agent injection connector 2, an agent leading-out connector 3, a regulating valve 4, a pressure detection module 5, an ROV handle 6, a protection cylinder 7, and a control module, where the base 1 is cylindrical, the protection cylinder 7 is coaxially fixed at one end of the base 1, the outer wall of the protection cylinder 7 is flush with the outer wall of the base 1, the agent injection connector 2 and the agent leading-out connector 3 are located in the protection cylinder 7, the agent injection connector 2 and the agent leading-out connector 3 are fixed at the end of the base 1, and the ROV handle 6 is installed at the other end of the base 1.

An injection port penetrates through the medicament injection connector 2, a lead-out port penetrates through the medicament lead-out connector 3, the injection port and the lead-out port are both round holes, the hole center line of the injection port and the hole center line of the lead-out port are parallel to the axis of the seat body 1, an adjusting flow channel is arranged on the seat body 1, and the adjusting flow channel comprises a medicament inlet flow channel 1a and a medicament outlet flow channel 1 b;

one end of the medicine inlet flow channel 1a is communicated with the injection port, and the other end of the medicine inlet flow channel 1a is communicated with the regulating valve 4;

one end of the medicine outlet flow channel 1b is communicated with the leading-out port, and the other end of the medicine outlet flow channel 1b is communicated with the regulating valve 4;

and the regulating valve 4 is respectively provided with a medicine inlet and a medicine outlet which are matched with the medicine inlet flow passage 1a and the medicine outlet flow passage 1 b.

The pressure measuring device is characterized in that a pressure measuring cavity is arranged in the base body 1, the pressure measuring cavity is also internally provided with the pressure detecting module 5, a medicine inlet pressure guiding channel 1c and a medicine outlet pressure guiding channel 1d are also arranged in the base body 1, one end of the medicine inlet pressure guiding channel 1c is communicated with the medicine inlet flow channel 1a, the other end of the medicine inlet pressure guiding channel is communicated with the pressure measuring cavity, one end of the medicine outlet pressure guiding channel 1d is communicated with the medicine outlet flow channel 1b, the other end of the medicine outlet pressure guiding channel is communicated with the pressure measuring cavity, the pressure detecting module 5 comprises two pressure detecting ends, the two pressure detecting ends respectively face the medicine inlet pressure guiding channel 1c and the medicine outlet pressure guiding channel 1d, and the periphery of the pressure detecting ends is sealed so as to ensure that chemical agents cannot permeate into the pressure measuring cavity.

In general, since the pressure of the chemical agent drawn from the chemical agent storage tank is high, it is necessary to depressurize the chemical agent first, and thus at least one depressurization section for steplessly depressurizing the fluid flowing through the chemical agent supply flow path 1a is connected in series to the chemical agent supply flow path 1 a. After the rough adjustment of the pressure reduction section, the pressure is further reduced by the adjusting valve 4, and the pressure flow rate of the medicament entering the medicament outlet flow passage 1b is accurately adjusted. The pressure reducing section can be constructed in various ways, for example, by using spiral flow channels and/or zigzag flow channels to form the pressure reducing section. The pressure reduction section is communicated with the detection end of the pressure detection module 5 through a middle pressure guide channel 1 e. The pressure detection module 5 adopts a temperature and pressure integrated pressure sensor to calibrate the working condition. The signal transmission end of the pressure detection module 5 is connected with the control module through a line, and the control module and the oil (gas) production platform transmit signals in a wireless or wired mode.

The ROV handle 6 is well documented in the existing patent documents, and the specific structure thereof is not described herein.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
