Abstract
The invention provides a check valve core sealed by mechanical and magnetic force, which consists of a check valve core main body, a movable gate and a balance weight. Magnetic force acts between the check valve core main body and the movable gate, the opened movable gate is gradually closed by the balance weight, and a water outlet of the check valve core is sealed by the movable gate under the action of magnetic force. The check valve core sealed by mechanical and magnetic force is opened and closed through the variation of water flow entering the check valve core. The check valve core sealed by mechanical and magnetic force has the advantages of small volume, rapid opening and closing, large water draining capability, good seal effect, strong self-clearing capability, simple structure, low manufacture cost, convenience for use and maintenance and the like.
Description
Technical field
The present invention relates to a kind of nonreturn valve core, especially a kind of mechanical magnetic seal nonreturn valve core.
Background technique
The drainage pipe one-way valve plays an important role in construction drainage as an important devices in the drainage system.The drainage pipe one-way valve should possess two kinds of fundamental functions: the one, and draining is smooth and easy, can get rid of the water in water appliance and the drainage pipe rapidly; The 2nd, good seal performance can effectively prevent in the foul smell inlet chamber in the drainage pipeline.Existing drainage pipe one-way valve generally adopts trap to replace, and the ubiquitous problem of trap mainly shows: 1. the water seal of trap is easily because of losing seal action after insufficient height or the water evaporation; 2. a little less than the drainage capacity of trap, be prone to the phenomenon of impeded drainage; 3. the self-purification ability of trap is poor, deposits hair, mud easily, forms to stop up; 4. trap water seal hold facility is poor, and easily malleation that is formed in the sewerage system or negative pressure are destroyed.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, volume is little, drainage capacity is strong, good sealing effect, not susceptible to plugging mechanical magnetic seal nonreturn valve core.
Mechanical magnetic seal nonreturn valve core of the present invention mainly is made up of nonreturn valve core main body, dodge gate and balance weight body.Magnet or magnetic material are equipped with in the water outlet place of nonreturn valve core main body, and outside also can being installed in both can being installed in, the quantity of magnet or magnetic material is 1 or several; Dodge gate is equipped with at the water outlet place of nonreturn valve core main body, dodge gate is installed on the nonreturn valve core main body by running shaft, dodge gate matches with water outlet on the nonreturn valve core main body, magnet or magnetic material also are equipped with in the corresponding part of magnet or magnetic material on dodge gate and the nonreturn valve core main body, the magnetic force of inhaling is mutually arranged between the two, reach the purpose of utilizing dodge gate leakproof one-way valve core water outlet; Dodge gate also can be made by magnetic material, comprises Hard Magnetic and soft magnetism; Be to increase sealing effect, nonreturn valve core main body water outlet sealing part can install elastic seal ring additional, seal ring be installed on the dodge gate or the nonreturn valve core main body on.Dodge gate can level be installed, and also can one angle be arranged with horizontal plane.Balance weight body is installed in the other end of dodge gate rotating shaft, and balance weight body is closed the dodge gate trend of opening, and reaches in the magneto motive scope; Restoring force after dodge gate is opened also can be magnetic force or elastic force, is provided by magnet or spring.The gravity of water is complementary in magnetic force between nonreturn valve core main body and the dodge gate and the nonreturn valve core main body, takes into account the drainage performance and the sealability of nonreturn valve core.
The invention has the beneficial effects as follows that mechanical magnetic seal nonreturn valve core volume is little, the water outlet bore is big, switch rapidly, current by the time resistance little, be difficult for obstruction, good sealing effect, strong, simple in structure, the convenient maintenance of self cleaning ability.Machinery magnetic seal nonreturn valve core is installed in the drainage pipe alternative existing trap, blowdown valve and floor drain core etc.
Description of drawings
Accompanying drawing is the structural representation of mechanical magnetic seal nonreturn valve core.
1. nonreturn valve core main bodys among the figure, 2. magnet, 3. dodge gate, 4. magnet, 5. seal ring, 6. rotating shaft, 7. balance weight body.
Embodiment
With reference to the accompanying drawings, mechanical magnetic seal nonreturn valve core is made up of nonreturn valve core main body 1, magnet 2, dodge gate 3, magnet 4, seal ring 5 and balance weight body 7.Magnet 2 is equipped with at the water outlet place of nonreturn valve core main body 1, dodge gate 3 is installed in the water outlet place of nonreturn valve core main body 1 by rotating shaft 6, seal ring 5 and magnet 4 are housed on the dodge gate 3, magnet 4 is corresponding with magnet 2, dodge gate 3 relies on the magnetic force that produces between magnet 4 and the magnet 2, and the water outlet of nonreturn valve core is sealed; The unlatching of dodge gate 3 relies on the gravity of water in the nonreturn valve core main body 1, is opened for suitable during with water 1/2-3/4; Balance weight body 7 is housed on the dodge gate 3, and balance weight body 7 can make dodge gate 3 trends of opening close, and reaches in the magneto motive scope.
Claims (4)
1. a mechanical magnetic seal nonreturn valve core has nonreturn valve core main body, dodge gate and balance weight body, it is characterized in that dodge gate is installed in the water outlet place of nonreturn valve core, and balance weight body is installed on the dodge gate, between nonreturn valve core main body and the dodge gate magnetic force is arranged; The dodge gate trend of utilizing balance weight body to make to open is closed, and utilizes magnetic force that dodge gate is sealed the water outlet of nonreturn valve core, utilizes the gravity of water in the nonreturn valve core main body that dodge gate is opened; By entering the variation of nonreturn valve core current, realize opening and closing of mechanical magnetic seal nonreturn valve core.
2. a kind of mechanical magnetic seal nonreturn valve core according to claim 1 is characterized in that on the said nonreturn valve core main body magnet or magnetic material being housed.
