The sealing ring located in the sealing ring groove 751 of the outlet surface plays a sealing role between the valve core outlet liner surface 729 and the valve body outlet plane hard layer 739. The pressure on the spool inlet lining surface 728 is greater than the pressure on the spool outlet lining surface 729 to ensure that the smooth flow of forward fluid will not cause backflow. The whole process can maintain work without consuming any additional energy consumption during the continuous period.

From the outlet elbow 731 to the circular flow passage port 721, the deformed flow passage 788 is blocked by the valve core inlet liner surface 728 at the annular flow passage port 722, and the sealing ring located in the inlet face seal ring groove 752 is on the valve core inlet liner surface 728 plays a sealing role with the flat hard layer 738 at the inlet of the valve body. The reverse fluid after being cut off can no longer reach the inlet elbow 732, and the pressure on the spool outlet liner surface 729 is greater than the pressure on the spool inlet liner surface 728, ensuring reliable and stable one-way cutoff. The entire cut-off duration can maintain the work without consuming any additional energy.

[0092] With the special design of the deformed flow channel 788 on the spool sector cylinder 725 that swings around the axis of the cylindrical shaft 710, the spool is pushed open by the initial force, and the remaining work can be accurate without consuming any additional energy during the whole process. Realize the opening and closing function of the one-way valve.

The surface roughness damage is far less than that of conventional stainless steel. The degree of surface roughness damage.

[0101] Table 3 shows the comparison between the spool inlet lining surface 728 and the spool outlet lining surface 729 of the zirconia ceramic lining plate and the conventional stainless steel spool inlet lining surface 728 and the spool outlet lining surface 729 for corrosion resistance and leakage experiment data. .

[0102] (Table 3) Experimental comparison table of spool inlet lining surface 728 and spool outlet lining surface 729

[0103]

[0104] According to the experimental data in Table 3, the surface wear of the zirconia ceramic liner is far less than that of 316 stainless steel.

[0105] Table 4 compares the corrosion resistance and impact test data of the nickel alloy steel of the present invention and 316 stainless steel.

[0106] (Table 4) Experimental comparison table of the valve body inlet flat hard layer 738 and the valve body outlet flat hard layer 739

[0107]

[0108] From the experimental data in Table 4, it can be seen that the surface roughness damage of the nickel alloy hard and corrosion-resistant materials is much less than that of the 316 stainless steel material.

[0109] The invention can ensure the normal operation of the system equipment before the major overhaul every year, and eliminates the hidden danger of stop failure of the cooling system of the electromechanical conversion unit of the offshore wind power platform due to the failure of the one-way valve.

[0110] 3. The present invention has the following outstanding substantive features and significant progress:

[0111] (1) There is a platform hinge 444 on the periphery of the working platform 410 connected with one end of the clamp piston two-way buffer 445, and the other end of the clamp piston two-way buffer 445 is connected with the fixed foot 446, and the clamp piston The two-way buffer 445 and the working platform 410 are arranged at an angle of 45 degrees to ensure that the working platform 410 is stably fixed.

[0112] (2) The clamp piston two-way buffer 445 adopts clamp connection combined with double piston seal shock absorption. Each clamp piston two-way buffer 445 can withstand tension or pressure at the same time, ensuring that the working platform 410 can resist any direction from any direction. The waves hit.

[0113] (3) The clamp horizontal check valve 490 is placed horizontally as a whole, and the spool sector cylinder 725 is located above the spool hole 781. If there are no springs or any obstructive parts in the integral part of the horizontal check valve 490, the deformed flow channel 788 and the annular flow are formed between the variable flow cone 724 part on the swing valve core 720 and the spool sector cylinder 725. The crossing 722 and the circular flow channel opening 721 are connected. The application of the clamp horizontal check valve 490 can ensure the normal operation of the system equipment before the major overhaul every year, eliminate the cooling accident caused by the failure of the one-way valve, and reduce the expensive maintenance costs that are difficult to repair in the harsh island environment.

[0114] (4) The surface roughness damage of the inner sealing piston 621 and outer sealing piston 936 made of zirconia ceramic material is far less than that of conventional stainless steel materials. The surface roughness of nickel alloy hard and corrosion-resistant materials is much smaller than that of 316 stainless steel.

[0115] (5) The present invention combines the clamp horizontal check valve 490 with the clamp piston two-way buffer 445 through the work platform 410, and at the same time solves the two major problems that have been plagued by offshore wind power generation: cooling pump start-up water diversion and buffering problems , And achieved unexpected results.
