Abstract
The utility model discloses a magnetic check valve, which comprises a fixing unit and a valve spool. A water outlet channel is arranged inside the fixing unit, the valve spool is connected into the fixing unit in a sliding manner and slides between a first position and a second position, the water outlet channel is in a blocked state when the valve spool is positioned at the first position, and the water outlet channel is in a through state when the valve spool is not at the first position. The fixing unit is fixedly provided with a first magnet, the valve spool is fixedly provided with a second magnet, the first magnet and the second magnet repel each other and generate repulsive force, and the direction of the repulsive force coincides with the sliding direction of the valve spool. The valve spool overcomes the repulsive force under the action of impact force of water flow in downstream, so that the valve spool moves from the first position to the direction of the second position, and the water outlet channel is in the through state. The valve spool moves from a non-first position to the direction of the first direction under the action of the impulsive force when the water flow is in backflow or cutoff, and the water outlet channel is in the blocked state.

Described fixed unit comprises a valve body 200, a valve seat 300 and an exterior seal ring 400.Described exterior seal ring 400 is set in turning surface outside the valve body 200.The turning surface place is concaved with a draw-in groove in the afterbody of described valve body 200, and turning surface convexes with an edge clipping outside the described valve seat 300, and described edge clipping and draw-in groove adapter are connected together, so that valve body 200 and valve seat 300 are fixed together.Among the present embodiment, form intake tunnel within described valve body 200 and the valve seat 300, the head of described valve body 200 becomes the feed-water end of intake tunnel, and described valve seat 300 becomes the waterexit end of intake tunnel.Turning surface inwardly convexes with an annular flange flange 210 within the described valve body 200, and described annular flange flange 210 has a sealing surface towards the waterexit end, and described sealing surface preferably is provided with the plane of inclination, to increase sealability.Be installed with a fixed base 310 within the described valve seat 300, the spoke 320 by some annular displays between the interior turning surface of described fixed base 310 and valve seat 300 is fixed together, and forms path between the adjacent spoke 320.The end towards feed-water end of described fixed base 310 is arranged with and is formed with one first mounting groove 311.Described first mounting groove 311 places are installed with one first magnet 500.
Described spool 100 comprises a sealing seat 110, and turning surface is arranged with an inner seal ring 120 outside the described sealing seat 110, and the external diameter of described inner seal ring 120 is between the maximum diameter and minimum diameter of the inclination sealing surface of described annular flange flange 120.The end face towards the waterexit end of described sealing seat 110 is arranged with and is formed with one second mounting groove 111.Described second mounting groove 111 places are installed with one second magnet 600.
The sealing seat 110 of described spool is slidingly arranged within the intake tunnel of fixed unit, and between the fixed base 310 of the annular flange flange 210 of valve body 200 and valve seat 300, and, practising physiognomy of described first magnet 500 and second magnet 600 to the end homopolarity, making wins produces repulsive force between the magnet 500 and second magnet 600, and described repulsive force line of action and spool slip line overlap.
In order to guarantee the glide direction of sealing seat 110, preferably set up a guide mechanism.Be installed with a guide rod 130 under the described sealing seat 110, an end of described guide rod 130 is fixed in the bottom center of second mounting groove 111, and described second magnet 600 is annular, and its socket guide rod 130 also is fixed in second mounting groove 111.Described fixed base 310 places offer a penetration hole 312, and described first magnet 500 is annular, the endoporus dead in line of described penetration hole 312 axis and first magnet 500 and alignment; The endoporus and the penetration hole 312 of adaptive and described first magnet 500 that is slidingly connected of described guide rod 130.
Among this enforcement, described spool 100 slides between the primary importance and the second place, described primary importance is meant that the inner seal ring 120 of described spool 100 is tight against the position on the sealing surface of the annular flange flange 210 of valve body 200, this moment, check valve was in blocking state, and the described second place is meant the position near first magnet 500.
When forward hydraulic pressure was too small, described hydraulic action was little at the active force of sealing seat 310, and described active force is less than repulsive force, and then spool 100 can't move, and spool 100 is in primary importance, and check valve is in blocking state, please refers to Fig. 3.
When forward hydraulic pressure is big, described hydraulic action is big at the active force of sealing seat 310, described active force is greater than repulsive force, then spool 100 begins to move, move to non-primary importance from primary importance, described non-primary importance is between the primary importance and the second place, and check valve is on state, please refers to Fig. 5.
During refluence, reverse water pressure occurs, described hydraulic action the making a concerted effort of described active force and repulsive force makes spool 100 remain on primary importance at the active force of sealing seat 310 and repulsive force in the same way, and check valve is in blocking state, please refers to Fig. 4.
Among another preferred embodiment, it and a last preferred embodiment difference are: the long-pending spool glide direction gradual change along primary importance to the second place of water section area excessively of described intake tunnel is little, and the difference that makes intake tunnel cross the cross sectional area of water section area and spool diminishes gradually.Described hydraulic pressure size is directly proportional with spool sliding distance size, the difference size that described sliding distance size and intake tunnel are crossed the cross sectional area of water section area and spool is inversely proportional to, can realize that then hydraulic pressure size and intake tunnel cross the difference size of the cross sectional area of water section area and spool and be inversely proportional to, can guarantee that the water yield is even, realize water saving.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
