The sealing cotton 3 is arranged, so that the air tightness of the pressure release valve can be effectively guaranteed, and air leakage is avoided.
Further, the magnet 4 is disposed on an outer wall surface of the lower baffle 122 along a length direction of the lower baffle 122, and the magnet 4 is located below the sealing cotton 3.
Further, referring to fig. 4 to 6, the magnets 4 are multiple, the magnets 4 are circular magnets, a rubber pad 6 is disposed between each magnet 4 and the lower baffle 122, each magnet 4 is respectively fixed to the lower baffle 122 through a screw 41, and each screw 41 penetrates through the corresponding magnet 4 and the corresponding rubber pad 6 to be connected to the lower baffle 122. Set up rubber pad 6 between magnet 4 and lower baffle 122, let magnet 4 atress occasionally an elastic adjustment space for magnet laminates with valve board 2 binding face is complete all the time, guarantees the magnetic attraction maximize, and closes the effect that plays the buffering when colliding with magnet at the valve board, avoids magnet to shake the bits of broken glass.
The magnetic pressure relief valve is a valve device which takes the attraction force of a magnet as a limiting force to calibrate the air pressure. When the central air conditioner operates, the pressure relief valve is in a closed state, the valve plate 2 and the magnet 4 on the frame 1 are attached together, and the magnet attraction force generated between the valve plate and the magnet is the safe pressure relief value of the pressure relief valve. Meanwhile, the valve plate 2 is positively acted by the air pressure in the unit, when the air pressure in the unit continuously rises to exert the acting force on the valve plate 2 to exceed the attraction force of the magnet, the magnetic force for separating the valve plate 2 from the magnet 4 disappears, and the air pressure in the unit at the moment can allow the valve plate to have a large acceleration to pop open instantly, so that the air pressure is timely discharged in a large amount. Set up a plurality of magnets 4, the limiting value of relief valve is adjusted to the number of accessible increase and decrease magnet 4, is fit for multiple operating mode and uses, and simple to operate easily maintains.
Furthermore, each magnet 4 is provided with a through hole for allowing the screw 41 to pass through, a countersunk seat is provided at one side of the through hole, and the screw head of the screw 41 is embedded into the corresponding countersunk seat after installation. The screw head sinks into the countersunk seat, so that the screw head is lower than the top surface of the magnet 4, and the joint of the magnet and the valve plate is not influenced.
Further, a reinforcing plate 21 is fixedly arranged on the outer surface of the valve plate 2. Set up reinforcing plate 21 and can play the effect of reinforcing bulk strength to valve plate 2, valve plate 2 warp all around when avoiding atmospheric pressure, influence magnet 4 and effective level laminating area with it, reduce magnetic attraction, make valve plate 2 open too early.
Further, a travel switch 5 is arranged on the inner wall surface of the outer frame 11, the travel switch 5 is connected with a control host of the central air conditioner, the travel switch 5 is a roller travel switch, when the valve plate 2 is closed, a roller of the travel switch 5 abuts against the valve plate 2, when the valve plate 2 is opened, the travel switch 5 acts, and the fan of the central air conditioner stops working when power is off. When the valve plate 4 is bounced open, the sensing arm of the travel switch is loosened, a power-off signal is fed back to the host, and the fan device is turned off in time. When the air pressure after pressure relief is small enough, the valve plate 2 slowly falls to the vertical position under the action of the gravity of the valve plate 2, the valve plate and the magnet 4 are attracted again, the valve plate 2 is closed, the travel switch 5 is pushed back to the original position at the moment, and the fan can continue to be electrified and operated.
Furthermore, the valve plate 2 is made of metal plates through bending, the left and right flanging edges are leveled, and the upper edge is bent. Therefore, the strength of the left side, the right side and the upper side of the valve plate 2 can be enhanced, the lower side is not subjected to enhancement treatment, and ductility is reserved, so that the magnet and the valve plate are favorably attracted and adhered tightly.
Further, the left side and the right side of the upper end of the valve plate 2 are respectively provided with a spring hinge 22, and the two spring hinges 22 are respectively connected with the left side and the right side of the outer frame 11.
The above mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention should not be limited thereby, that is, all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still included in the scope of the present invention.
