Abstract
The invention discloses a high-temperature-resistant gas valve which comprises a valve mechanism, a pneumatic mechanism and a heat-insulation mechanism. The valve mechanism is provided with a valve 0, an inlet flange 1 and an outlet flange 7 are arranged on the valve 0, a sealing plug 2 is arranged in the valve 0, a sealing rod 3 is arranged in the sealing plug 2, a coupling 4 is arranged on the sealing rod 3, the valve 0 is made of heat-resistant stainless steel by means of gravity casting by the aid of a heat-resistant laminated sand mould, and the sealing plug 2 is made of high-temperature ceramics; the pneumatic mechanism is provided with a cylinder 5, and a piston 6 is arranged in the cylinder 5; the heat-insulation mechanism is provided with a heat-insulation sleeve 8; the heat-insulation sleeve 8 is made of polycrystalline mullite fibers. The high-temperature-resistant gas valve has the technical advantages that the valve 0 is made of the heat-resistant stainless steel, and the working temperature of the sealing plug 2 made of the high-temperature ceramics can reach 950 DEG C, so that the requirement on recycling gas in a furnace at the temperature of 800 DEG C can be met; the high-temperature-resistant gas valve is controlled by the pneumatic mechanism and is simple in structure and convenient to control, accordingly, the work efficiency of the low-pressure casting furnace can be improved, and energy and the cost can be saved.
Description
Technical field
The energy that the present invention relates to casting field is reused, specifically a kind of high temperature resistant air valve.
Background technique
It at casting field low-pressure die casting stove, is the routine equipment of the aluminium alloy castingses such as casting hub, but owing to being also greater than the air valve of 900 degree on market without serviceability temperature, every casting is once just emptying the high-temperature gas in stove, the pressurized gas of normal temperature reinjects, again the burner hearth being cooled is heated, not only wasted the energy for this reason, increased cost of production, also, because low pressure intestine evacuation velocity is slow, efficiency is also low.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of high temperature resistant air valve, energy-saving cost.
According to technological scheme of the present invention: a kind of high temperature resistant air valve, comprises valve body mechanism, pneumatic mechanism, heat preservation mechanism.
Described valve body mechanism is provided with valve body 0, on valve body 0, be provided with suction flange 1, outlet(discharge) flange 7, in valve body 0, be provided with sealing plug 2, in sealing plug 2, be provided with seal bar 3, in seal bar 3, be provided with shaft joint 4, described valve body 0 is used heat-resistance stainless steel, and with heat-resisting overlay film sand mo(u)ld gravity casting, sealing plug 2 is used refractory ceramics to make.
Described pneumatic mechanism is provided with cylinder 5, is provided with piston 6 in cylinder 5.
Described heat preservation mechanism is provided with lagging 8; Described lagging 8 adopts mullite polycrystalline fibre.
Technique effect of the present invention is; The valve body 0, the refractory ceramics that adopt heat-resistance stainless steel to make are made sealing plug 2 operating temperatures and can be reached 950C degree, meet the requirement that furnace gas 800C degree recycles, adopt pneumatic mechanism to control high temperature resistant air valve, control simple in structure is convenient, make low-pressure die casting stove improve work efficiency, energy-saving cost.
