Abstract
The invention discloses a socket-type anti-sedimentation expansion-wire tightening flap-valve check valve allowing control medium only to flow in one direction and preventing the control medium to flow in the opposite direction. An upper top cover (3) is movably locked to the upper end of a top cover body (3), a water discharging cover plate (4) is movably arranged on the inner bottom end of the top cover body (2), the top cover body (2) is fixed on the upper end of a check valve body (1) through fixed screw threads (8), a movable flap valve (6) is arranged on the inner middle part of the check valve body (1), and an expansion wire tightening mechanism is arranged on the upper end of the outer wall of the check valve body (1) and is connected with an embedded fixed pipe. By designing the movable flap valve, the movable flap valve is automatically opened when the water is discharged, and the water is not contacted with drain cleaner, so that the sludge is reduced. By arranging multiple screw threads and rubber sealing rings, the leakage can be prevented; by adopting the ASA material which can resist the ultraviolet, aging, high temperature and low temperature, the sedimentation situation is easy to observe, and the socket-type anti-sedimentation expansion-wire tightening flap-valve check valve is convenient to overhaul.
Description
Technical field: the present invention relates to control media and only allow to flow to a direction, and stop the fastening flap type check valve of the swollen silk of the anti-alluvial of a kind of spigot and socket type of flowing in the other direction.
Background technique: against current valve is a kind of and allows medium to flow to a direction, and stops mobile valve in the other direction.This valve is under the mobile fluid pressure action of direction, and flap is opened; When fluid flows in the other direction, by hydrodynamic pressure and the flap that certainly overlaps act on valve seat, thereby cut off, flow, prevent from flowing backwards.Against current valve can divide according to its structure: a rise-fall type against current valve, flap slides along valve body vertical center line.Two, rotary-open type against current valve, i.e. the bearing pin rotation of flap outside valve body.Three, dish formula against current valve, flap rotates around the bearing pin in valve seat.Four, tubular type against current valve, flap slides along valve body center line.But the restriction that the position that these against current valves are installed has, and complex structure, sealing effect of sedimentation reduction is not obvious, and use and maintenance is inconvenient.
Summary of the invention: the object of the present invention is to provide and can prevent from causing displacement or the leakage hidden danger of the formation that comes off under not clear active force, be easy to observe alluvial situation, the fastening flap type check valve of the swollen silk of the anti-alluvial of a kind of spigot and socket type of easy access.
The technological scheme that the present invention adopted is for achieving the above object: its upper top cover 3 active buckles are in top cover body 2 upper ends, and water drainage cover board 4 is movably placed in the interior bottom of top cover body 2, and top cover body 2 is fixed on check valve case 1 upper end by fixing screw thread 8; Movable flap valve 6 use copper axles and bearing 14 flexible connections, and be placed on check valve case 1 interior edge face, silicone gasket 15 is arranged in the lower bayonet slot of movable flap valve 6, and the internal tapered hole 5 on check valve case 1 interior edge face is tightly connected, and is arranged on the interior middle part of check valve case 1; The check valve case 1 outer wall movable upper end of swollen silk retention mechanism arranges movable pressure ring 12, and and the lower pressure ring 11 at top cover body 2 sidewall middle parts is flexibly connected, rubber seal 9 is placed in movable pressure ring 12 lower ends, and isolation loose collar 13 is arranged in the middle of upper and lower two rubber seal 9, and is connected with pre-buried fixed tube.
The invention has the beneficial effects as follows: owing to having designed movable flap valve, constantly automatically opening to check valve case internal drainage, formed independent water space, do not exchanged with outer water, reduced mud.Multiple tracks screw thread and rubber seal are set, have prevented the leakage hidden danger that causes displacement or come off and form under not clear active force.Upper top cover and top cover body adopt antiultraviolet, anti-aging, high temperature resistant and low temperature resistant ASA material, are easy to observe alluvial situation, easy access.And simple in structure, easy to use.
Accompanying drawing explanation: Fig. 1 is structural representation of the present invention
During Fig. 2, the A-A of Fig. 1 is to view
Embodiment: as shown in Figure 1 and Figure 2, its upper top cover 3 active buckles are in top cover body 2 upper ends, and water drainage cover board 4 is movably placed in the interior bottom of top cover body 2, top cover body 2 is fixed on check valve case 1 upper end by fixing screw thread 8; Movable flap valve 6 use copper axles and bearing 14 flexible connections, and be placed on check valve case 1 interior edge face, silicone gasket 15 is arranged in the lower bayonet slot of movable flap valve 6, and the internal tapered hole 5 on check valve case 1 interior edge face is tightly connected, and is arranged on the interior middle part of check valve case 1; The check valve case 1 outer wall movable upper end of swollen silk retention mechanism arranges movable pressure ring 12, and and the lower pressure ring 11 at top cover body 2 sidewall middle parts is flexibly connected, rubber seal 9 is placed in movable pressure ring 12 lower ends, and isolation loose collar 13 is arranged in the middle of upper and lower two rubber seal 9, and is connected with pre-buried fixed tube.
As shown in Figure 1, described top cover body 2 lower wall middle parts arrange lower pressure ring 11.
As shown in Figure 1 and Figure 2, described top cover body 2 inner bottom part peripheries equidistantly arrange open-work 10.
As shown in Figure 1, described check valve case 1 outer wall middle part arranges boss 7, and its upper end arranges rubber seal 9.
The present invention manufactures installation requirement: 1, use material to be uvioresistant, anti-aging, low temperature resistant, heat-resisting ASA material; 2,1.5 times of the anti-mud top cover of check valve water outlet area >=check valve water intake area; 3, be arranged on check valve case and exceed concrete plane≤5cm, connecting means is identical with former check valve top cover screw thread; 4, drain opening cover plate proportion should be 1.2 ± 0.5; 5, the anti-mud top cover of check valve in channel in hydraulic pressure >=external water pressure situation in full closeding state.
Working principle of the present invention is: when river or underground water are pushed movable flap valve open, under the effect that enters water in check valve case, automatically open, river or underground water discharge are in channel, under normality by the effect of certainly hanging down in closed state, form independent water space, do not exchange with outer water, reduce alluvial, and complete and fall closure after rise with working state.
