Description

Gas magnetic cut-off valve

Technical field

The utility model gas magnetic cut-off valve belongs to the control valve technical field of gas pipeline.

Background technique

Gas piping technical field at home and abroad often adopts the break-make of electromagnetic valve gas, particularly gas range adopts electromagnetic valve combustion gas break-make very general, its technology is very ripe, as more domestic large-scale advanced gas water-heater industries, all adopt solenoid valve to control the break-make of combustion gas on the air supply system of gas water-heater, solenoid valve produces magnetic field by hot-wire coil and comes work.

For a long time, the indoor valve of using in the gas technology field mainly contains stopcock, ball valve, butterfly valve, and above-mentioned valve is the face contact mostly at airtight position, and sealing contact surface is big more, and manufacture difficulty is just big more, and tightness is poor more, and the switching resistance is big more.The valve that uses between gas pipeline and the gas range particularly and since frequent open and close a period of time after, leak the phenomenon that leaks in can occurring, open and close effort, and easy-maintaining not, assembly interchangeability is poor.In case certain damage parts must be changed whole valve body.The now normal mostly maintaining method that adopts intermittent oiling, but the very trouble of sensation that operates, the user is difficult to accomplish.

The model utility content

The utility model provides a kind of gas magnetic cut-off valve, it is a kind of magnetic control valve of sealing contact surface circlet shape line contact, what adopt is manual magnetic induction, and non electromagnetic induction is fit to indoor outer the use, opened manually or close, the valve preparation process is simple, the precision height, good seal performance, and with low cost.

In order to address the above problem, the scheme that the present invention adopts is: gas magnetic control valve, mainly comprise: valve body, valve block, spring, magnet and valve rod, baffle plate is horizontally installed on the middle part of valve body, the top of valve body is gas-entered passageway A, the bottom of valve body is outlet passageway C, the right side of valve body is side canal B, gas-entered passageway A and the free intercommunication of side canal B, baffle plate and outlet passageway C form valve opening in right upper portion, side canal B and outlet passageway C realize intercommunication by valve opening, left end in side canal B inner valve stem is fixed with valve block, in the stem sleeve in the T type that is sleeved on the to the right lid of valve rod, the left end of spring is sleeved on a side of valve rod, and withstand valve block, valve block withstands the edge of valve opening left, block valve opening, the right-hand member of spring is sleeved on outside the stem sleeve of T type lid, and withstand the left wall of T type lid, T type lid is fixed on the passway of side canal B by sealing thread, on the outer wall at valve body side canal B top hinge is installed, the neutral position of movable branching rod is hinged on the hinge, and the lower end of movable branching rod is fixed with external magnet.

The right-hand member of above-mentioned valve rod is connected with internal magnet, and internal magnet and external magnet are a pair of different in nature permanent magnet.

The right side edge of above-mentioned valve opening is provided with convex parts.

The beneficial effect that the utility model compared with prior art has is: the utility model gas magnetic cut-off valve middle valve plate is that annular wire contacts with the surface of contact at valve opening edge, sealing contact surface is very little, surface of contact is 1/10th of a conventional valves, and the big more seal of gas pressure is good more in the pipeline.Valve operation is simple, opens and closes laborsavingly, and break-make is rapid, and any sealing compound and oiling agent in use need not to annotate.Gas magnetic cut-off valve is in use easy to maintenance, all part manufacturing specification unanimities, excellent interchangeability.Valve opened manually or close is particularly suitable for indoor outer the use.
