Vertical weld joint backstop 10 assembling process:

Blocking internal thread 152 is coated with sealing resin and technique screw 151 close fit; Respectively spool lower sealing ring 159 is put in the spool lower seal groove cavity 155 of spool lower peripheral surface 115, on spool spool upper sealing ring 178 being put into sphere 117 on spool in sealing groove 177; Again upright spool 110 entirety is placed in the pipe inner circle 121 of cylindrical duct 120.

Allow the lower interior hemisphere face 196 on lower welding joint hemispherical Shell 190 has between recessed circular groove 193 inner circle and pipe cylindrical 123 is transition fit, the low groove baseplane 194 on recessed circular groove 193 and contacting for sealing between the pipe lower surface 129 in cylindrical duct 120; Allowing the upper interior hemisphere face 187 on welding joint hemispherical Shell 180 has between fovea superior circular groove 183 inner circle and pipe cylindrical 123 is transition fit, contacting for sealing between the upper groove baseplane 184 on fovea superior circular groove 183 and the pipe upper surface 128 in cylindrical duct 120.

Fixing with 12 groups of valve casing bolt and nut groups 140 sealing location between upper flange annulus 189 on lower flange annulus 198 on lower welding joint hemispherical Shell 190 and upper welding joint hemispherical Shell 180.

Use procedure, vertical weld joint backstop 10 is overall vertical to be placed, the overall proportion of upright spool 110 with spool internal cavity 156 be the weight of every 1 mm cube between 1.2 grams to 1.3 grams, slightly overweight sea water specific gravity.Vertical weld joint backstop 10 is in stopping state time static.

Vertical weld joint backstop 10 principle of work:

The overall vertical placement of vertical weld joint backstop 10, in Figure 11, when seawater from seabed water strainer 11 flows from bottom to top, promote upright spool 110 moves, seawater flows through runner residing for spool annular aperture 119, enter into ring-type six tracts even runner residing for muscle runner 157, then after flowing through runner residing for spool circular hole 118, flow out after entering into lifting water inlet pipe 21 upper semisection and drawn by low-pressure centrifugal pump 20 import.

In Figure 12, from low-pressure centrifugal pump 20 import seawater because of unforeseen circumstances from top to bottom adverse current time, promote upright spool 110 to move down, spool lower peripheral surface 115 and lower interior hemisphere face 196 are fitted, and the spool lower sealing ring 159 on spool lower peripheral surface 115 guarantees that runner is cut off closedown.Top-down seawater passes through runner residing for spool circular hole 118, be cut off after entering into runner residing for ring-type six company muscle runner 157 again, effective prevention adverse current avoids mishap and occurs, and work whole process just can realize backstop effect without the need to additionally consuming any energy consumption again.

The main body assembling process of horizontal welding joint backstop 80:

Put into by rotation spool 200 among welding joint valve body 300, spool pipe cambered surface 802 is positioned among valve body circle cancave cambered surface 602.

Cylinder axis 100 cylindrical coordinates through spool circular hole 801 rotary sliding of rotation spool 200.

Put sealing-ring well in advance in dead axle seal groove 509 on the enclosing cover axis hole 901 of two outer end caps 900, allow the end cap inner plane 908 of two outer end caps 900 respectively towards the valve body side plane 306 of welding joint valve body 300 both sides, enclosing cover axis hole 901 aims at cylinder axis 100.

40 trip bolts 700 are each passed through that screw hole 207 on the end cap counterbore 907 of outer end cap 900 and the valve body side plane 306 of welding joint valve body 300 is fastening to match, and are close to airtight by end cap inner plane 908 and the valve body side plane 306 of outer end cap 900.

Pipeline assembling process:

Connection straight tube termination (307) on welding joint valve body 300 there is solder design groove (305) to design, guarantees can airtightly be connected with exterior line and safe and reliable.

The use procedure of horizontal welding joint backstop 80:

Welding joint valve body 300 on horizontal welding joint backstop 80 is horizontally disposed, spool fan-shaped cylinder 205 is positioned at above spool circular hole 801, angle between valve body inletpiston hard layer 308 and valve outlet plane hard layer 309 is 90 degree, and the angle between spool entrance end plane 208 and spool exit end plane 209 is 52 degree.During forward flow, the spool exit end plane 209 of spool fan-shaped cylinder 205 turns clockwise 19 degree and just can be attached on valve outlet plane hard layer 309 by fluid thrust, makes circular flow channel mouth 201 pairs of outlet elbows 301; Fluid is from annular flow road junction 202 after being out of shape six tracts of runners 808, and the fluid being pooled to circular flow channel mouth 201 flows out from outlet elbow 301; During countercurrent flow, the spool entrance end plane 208 of spool fan-shaped cylinder 205 is rotated counterclockwise 19 degree and just can be attached on valve body inletpiston hard layer 308 by fluid thrust, because annular flow road junction 202 and import bend pipe 302 stagger, fluid from circular flow channel mouth 201 after being out of shape six tracts of runners 808, be stopped in annular flow road junction 202, cannot flow out from import bend pipe 302, make, without any obstruction parts such as springs in integral unit of the present invention, just can realize uniflux function.

In Figure 16, when forward fluid is come in from import bend pipe 302, after the spool exit end plane 209 that initial fluid promotes spool fan-shaped cylinder 205 is adjacent to valve outlet plane hard layer 309, runner defines: from import bend pipe 302 to annular flow road junction 202 through being out of shape six tracts of runners 808 from circular flow channel mouth 201 out, then from the smooth and easy process that outlet elbow 301 is gone out.Sealing-ring in exit face seal groove 501 plays sealing function between spool exit end plane 209 and valve outlet plane hard layer 309.Spool entrance end plane 208 pressure is greater than spool exit end plane 209 pressure, guarantees that the forward fluid of Channel Group can not produce backflow phenomenon.Whole process duration just can maintenance work without the need to additionally consuming any energy consumption.

In Figure 17, when counter fluid is come in from outlet elbow 301, after the spool entrance end plane 208 that initial fluid promotes spool fan-shaped cylinder 205 is adjacent to valve body inletpiston hard layer 308, runner is cut off.Blocked by spool entrance end plane 208 during from outlet elbow 301 to circular flow channel mouth 201 through being out of shape six tracts of runners 808 at annular flow road junction 202, the sealing-ring in inlet face seal groove 502 plays sealing function between spool entrance end plane 208 and valve body inletpiston hard layer 308.Be cut off the counter fluid after circulation and cannot arrive import bend pipe 302 again, spool exit end plane 209 pressure is greater than spool entrance end plane 208 pressure, guarantees that unidirectional cutoff is reliable and stable.Just can maintenance work without the need to additionally consuming any energy consumption duration of whole cut-off.

Design especially by means of the six tracts of runners 808 of the distortion on the spool fan-shaped cylinder 205 around the rotation of cylinder axis 100 axial line, achieve after starting force pushes spool open, residue work is omnidistance without the need to additionally consuming any energy consumption, just accurately can realize the opening and closing function of backstop.
