Abstract
The utility model discloses a magnetic force safety valve for a boiler which is a safety device used for discharging steam when the steam pressure of the boiler is more than the rated value and is characterized in that a magnetic cover in which a coil is arranged is combined on an original safety valve; a magnet ring connected to a valve stem by a supporting stem is arranged in the magnetic cover; the magnetic force safety valve of the utility model combines the original safety valve and an electromagnet part integrally. The utility model has the advantages of simple structure, compactness, small size and convenient installation.
Description
The vapor pressure safety valve of existing boiler mostly is mechanical spring formula safety valve.This kind valve with length of spring compressed tension force as pilot pressure.Because spring and valve seat under factor effects such as high-temperature gas or corrosion, make the cracking pressure error of its safety valve occur accident greatly for a long time.Normally open for the level pressure that guarantees safety valve, use automatically controlled safety valve then again, disclose a kind of magnetic valve controller as the patent No. 86204450.The safety valve of this control gear separates part with electric controller by two and combines by mechanical transmission, is by pressure gauge electrical pickoff control auxiliary reclay, by the circuit of relay control electromagnetism operating valve; The actuating strut of electromagnetism operating valve drives fork and moves the unlatching of controlling safety valve, and the connecting arrangement of this separation is convenient, also more numerous and diverse inadequately in installing and using.
The purpose of this utility model is to overcome the deficiency that above-mentioned safety valve exists, and is a kind of safety valve or electromagnetism partly to be combined as a whole, and makes it simple and compact for structure, a kind of magnetic safety valve of being convenient to install and use.
Major character of the present utility model be on former safety valve in conjunction with a magnetic cover, the coil that produces magnetic field is housed in magnetic cover the inside; Connect a pole in former valve rod upper end, connect on the pole and adorn a magnet ring.
Accompanying drawing is the structural representation of this safety valve.
Magnetic cover 1 is hollow circle, and following circle edge can be combined on the emergency valve seat limit 3 with bolt 2; The coil 4 of can packing in the magnetic cover; Magnet ring 5 is connected on the valve rod 7 of safety valve by pole 6.
The course of action of this valve is; After vapor pressure reached authorized pressure in the boiler, the electrical pickoff on the pressure gauge was connected, and the auxiliary reclay action makes the coil electricity in the magnetic cover produce magnetic field, attracts magnet ring to move up, and drives the valve rod action then, and valve seat is opened, and discharges gas.
Characteristics of the present utility model are improved original safety valve, namely utilize former safety valve, and install electromagnetism additional partly on top, make it in conjunction with as a whole, make on its structure simple, compactness is more reasonable, is convenient to install and use, cost of manufacture is also lower.
