Chinese patent CN202646853U has announced a kind of hemisphere valve body, comprise the cue ball face, cue ball face two ends are provided with connecting cylinder and lower connecting cylinder on one, respectively offer a upper and lower connecting through hole on upper and lower connecting cylinder, the cue ball face is a hemisphere, and its hemisphere boundary line is V-notch, upper attachment hole is provided with gear grooved, the spherome surface surfacing has alloy-layer, and the whole surfacing stellites of spherome surface strengthen spheroid hardness; Guarantee that matrix surface does not come off simultaneously, improve sealability, the particulate matter that also can resist in the media such as oil, cement, coal slurry washes away, and has self-cleaning function, and the spheroid that increases the service life designs with v-notch, can effectively regulate rate-of flow.But this patent structure is comparatively complicated, manufactures loaded down with trivial details.
The model utility content
The purpose of this utility model be exactly in order to overcome the defect that above-mentioned prior art exists, provide a kind of be applicable to fibrous fluid, flow resistance little, seal reliable side-mounted V-arrangement semispherical valve.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of side-mounted V-arrangement semispherical valve, comprise valve body, hemisphere, upper valve rod, spanner, gland, lower valve rod and bottom flange, described hemisphere is located in valve body, insert in valve body the lower end of described upper valve rod, and be connected with hemispheroidal upper end, the upper end of upper valve rod is connected with the spanner that is located at the valve body outside, described gland is set in upper valve rod top and is fixedly connected with valve body, insert in valve body the upper end of described lower valve rod, and be connected with hemispheroidal lower end, the lower end of lower valve rod is connected with the bottom flange on being fixed on valve body, offer the V-arrangement passage on described hemisphere.
The two ends up and down of described V-arrangement passage all offer attachment hole, and described upper valve rod is connected with the attachment hole of the upper end of V-arrangement passage, and described lower valve rod is connected with the attachment hole of the lower end of V-arrangement passage.
The angle of described V-arrangement passage is 90 °.
The junction of described hemisphere and valve inner is provided with seal ring.
Between described gland and valve body, be bolted.
The joint of described gland or bottom flange and valve body is provided with polytetrafluoroethylene packing.
Described hemisphere is Stainless Steel Ball.
Described bottom flange, lower valve rod, valve body, upper valve rod, gland, bolt all adopt Structural Hardware.
Drive hemisphere by rotating spanner and rotate, due to the hemisphere inboard, offering is a V-arrangement passage, between V-arrangement passage and valve body, shear action is arranged, and is particularly suitable for the media such as fibre-bearing, small solid particle, slip.When by spanner, driving the hemisphere half-twist, at the valve body inlet/outlet, place all presents sphere, thereby blocks mobile, open and close rapidly, need only half-twist from the standard-sized sheet to the complete shut-down, be convenient to remote control, sealing surface and the sphere closed state of being everlasting, be difficult for by the medium erosion.
Compared with prior art, the utlity model has following advantage:
One, be a V-arrangement passage in hemisphere, between V-arrangement access portal and valve body, shear action arranged, be particularly suitable for the media such as fibre-bearing, small solid particle, slip.
Two, fluid resistance is little, simple in structure, volume is little, lightweight, easy to operate.
Three, closely reliable, good seal performance, applied widely.
Four, when standard-sized sheet or full cut-off, can not cause the erosion of valve sealing face.
