Abstract
An insulation jacket-type eccentric rotary valve with heat-insulating function can be applied to the industries of brimstone, MDI, polyester and the like and adopts the technical scheme that the insulation jacket-type eccentric rotary valve comprises a valve body, a valve seat and a valve core. The insulation jacket-type eccentric rotary valve is characterized in that an insulation jacket is welded at the periphery of the valve body; the valve seat is movable; a pretension spring is arranged between the valve body and the valve seat and enables the valve seat and the valve core to be jointed tightly; and a sealing piece is arranged on the junction surface of the valve body and the valve seat.
Description
Technical field
The utility model relates to a kind of camflex valve, particularly a kind of insulation jacket camflex valve with heat insulation function.
Background technique
Camflex valve is the widely used class valves of industry such as Coal Chemical Industry, refinery, rock gas, metallurgy, electric power, and suitable medium has been contained gas, liquid, Dual-Phrase Distribution of Gas olid body, liquid-solid two-phase fluid etc.Camflex valve is that just develop recent years a kind of has novel structure, good seal performance, long service life, the operation moment of torsion is little, the new product of advantages such as wide accommodation, its application is very extensive, but generally all very high to temperature requirement in industries such as sulphur, MDI, polyester, has limited the application of common camflex valve.
The model utility content
The purpose of this utility model provides a kind ofly to be had and can and have the insulation jacket camflex valve of heat insulation function in sector applications such as sulphur, MDI, polyester.
The purpose of this utility model is achieved through the following technical solutions: the insulation jacket camflex valve, comprise valve body, valve seat and spool, and it is characterized in that insulation jacket being arranged in the peripheral solder of valve body.
Valve seat is removable valve seat, is provided with the preloading spring that valve seat and spool are fitted tightly between valve body and the valve seat, is provided with Sealing on the junction plane of valve body and valve seat.
Valve body and spool are eccentric structure, adopt the single piece type valve body.
Effect of the present utility model is: the insulation jacket camflex valve, comprise valve body, valve seat and spool, and it is characterized in that insulation jacket being arranged in the peripheral solder of valve body.Insulation water is got rid of from water outlet by the space between water intake inflow insulation jacket and the valve body again, makes valve inner keep certain temperature.
Valve seat is removable valve seat, is provided with the preloading spring that valve seat and spool are fitted tightly between valve body and the valve seat, is provided with Sealing on the junction plane of valve body and valve seat.Make removable valve seat keep certain seal pressure with spool all the time by preloading spring.
The insulation jacket camflex valve has heat insulation function, and the operating mode of insulation requirement can be arranged in industries such as sulphur, MDI, polyester.
Description of drawings
Fig. 1 is the structural representation of chuck insulation camflex valve;
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment
Now accompanying drawing is further described the utility model in conjunction with the embodiments, and certain protection domain of the present utility model is not limited to the embodiment in the accompanying drawing.
As shown in Figure 1, the utility model chuck insulation camflex valve, comprise upper valve rod 5, lower valve rod 2, upper bearing (metal) 8, lower bearing 3, the valve body 1 of band insulation jacket, spring 9, spool 4, valve seat 6, gland 7, drive upper valve rod 5 by actuator and reach spool 4 rotations that are connected with upper valve rod 5 splines, thereby reach valve opening and closing process (referring to Fig. 2), upper valve rod 5 has upper bearing (metal) 8 and lower bearing 3 to support respectively with lower valve rod 2, upper valve rod 5 has a throw of eccentric with the sphere centre of lower valve rod 2 and valve seat 6 and spool 4, realize that by this throw of eccentric spool 4 has cam wedging effect at the relative valve seat 6 of opening-closing process, make 4 pairs of valve seats of spool 6 produce certain seal pressure; There is the valve seat 6 of certain mobile space to guarantee that by gland 7 and spring 9 spool 4 is had certain seal pressure in off position all the time in addition.Periphery at valve body 1 is welded with insulation jacket, insulation water is from the cavity between water intake inflow valve body and the insulation jacket, flow out from outlet, continuously be incubated water by valve body 1 periphery and make valve inner keep certain temperature, can be applied to the operating mode that insulation requires.
Valve seat is removable valve seat, be provided with the preloading spring that valve seat and spool are fitted tightly between valve body and the valve seat, on the junction plane of valve body 1 and valve seat 6, be provided with Sealing 11, on the surface of contact of spool 4 and valve seat 6, doctor blade device 12 is set, makes removable valve seat keep certain seal pressure with spool all the time by preloading spring.
Claims (3)
1, insulation jacket camflex valve comprises valve body, valve seat and spool, and it is characterized in that has insulation jacket in the peripheral solder of valve body.
2, insulation jacket camflex valve according to claim 1 is characterized in that valve seat is removable valve seat, is provided with the preloading spring that valve seat and spool are fitted tightly between valve body and the valve seat, is provided with Sealing on the junction plane of valve body and valve seat.
