Integral level of the present invention is placed, and spool fan-shaped cylinder 25 is positioned at spool circular hole 81 tops.
In Fig. 1, when forward fluid is come in from import bend pipe 32, the spool pelvic outlet plane 29 that initial fluid promotes spool fan-shaped cylinder 25 is adjacent to after valve outlet port plane hard layer 39, runner has formed: from import bend pipe 32 to ring runner mouth 22 through distortion runner 88 from circular flow channel mouth 21 out, the more smooth and easy process of going out from outlet elbow 31.Seal ring in exit face seal groove 51 plays seal action between spool pelvic outlet plane 29 and valve outlet port plane hard layer 39.Spool inletpiston 28 pressures are greater than spool pelvic outlet plane 29 pressures, guarantee that the forward fluid of Channel Group can not produce backflow phenomenon.Overall process duration without extra consume any energy consumption just can maintenance work.
In Fig. 2, when counter fluid is come in from outlet elbow 31, the spool inletpiston 28 that initial fluid promotes spool fan-shaped cylinder 25 is adjacent to after valve inletpiston hard layer 38, and runner is cut off.Blocked by spool inletpiston 28 in the time being out of shape runner 88 at ring runner mouth 22 from outlet elbow 31 to circular flow channel mouth 21, the seal ring in inlet face seal groove 52 plays seal action between spool inletpiston 28 and valve inletpiston hard layer 38.The counter fluid being cut off after circulation cannot arrive import bend pipe 32 again, and spool pelvic outlet plane 29 pressures are greater than spool inletpiston 28 pressures, guarantees that unidirectional cutoff is reliable and stable.The duration of whole cut-off, consume any energy consumption with regard to energy maintenance work without extra.
By means of distortion runner 88 special designs on the spool fan-shaped cylinder 25 around cylinder axis 10 shaft axis rotations, realize starting force and pushed open after spool, residue work whole process, without any energy consumption of extra consumption, just can accurately realize the opening and closing function of one-way valve.
Following table adopts the corrosion-resistant and combined impulse laboratory data contrast of zinc alloy hard anticorrosive material of the present invention and conventional two phase stainless steel material, and the surface roughness damage situations of visible zinc alloy hard anticorrosive material is much smaller than the surface roughness damage situations of conventional two phase stainless steel material.
Corrosion-resistant and combined impulse experiment contrast table
Without any obstruction parts such as springs in one-piece element of the present invention, between bend flow channel cone 24 parts on employing rotation spool 20 and spool fan-shaped cylinder 25, forming distortion runner 88 is connected with ring runner mouth 22 and circular flow channel mouth 21, in conjunction with drawing in corrosion-resistant and the combined impulse laboratory data table of comparisons, before annual system equipment general overhaul, can normally move, thoroughly eliminate the hidden danger that affects oil field system pipeline and stop fault because of one-way valve fault.
