Description
The present invention relates to the special device of plunger valve, plunger valve lining method and this method in the chemical industry equipment.
At present, the plunger valve that adopts in the chemical industry equipment is made of valve body, support, handwheel, seal ring, plunger, valve rod, valve gap etc., the not good materials of decay resistance such as the material polyphyly gray cast iron of its valve body, plunger, support and carbon steel have caused the working life of valve short.In the last few years, some valves such as stronger material such as polychlorotrifluoroethylene or the perfluoroethylene-propylene etc. of back boxing corrosion resistances such as stop valve, membrane valve, but because the structure of plunger valve, especially the shape of support, be difficult to the lining bag, so that do not have the stronger plunger valve of lining bag decay resistance to come out at present as yet as fluoroplastic.
The objective of the invention is to avoid above-mentioned deficiency and provide plunger valve ， And that the method for plunger valve back boxing resistant material and the special device of this method are provided by the resistant material lining.
Purpose of the present invention can reach by following technical measures:
Valve body back boxing fluoroplastic, support, plunger parcel fluoroplastic.
With the mould device of fluoroplastic parcel plunger valve support, constitute by patrix, core, outlet matrix, following die cap, barrel, the whole And component for fixing of accent etc., the outlet matrix is seated in the exit position of plunger valve support, and its shape is similar to the support outlet.
The method of parcel plunger valve support is that: Tiao Zheng And is fixedly behind barrel inner support and the position of support outlet matrix in support exports, add fluoroplastic, its amount is corresponding with the support specification, then with the entire die heating, and pressurization when fluoroplastic melt, when initial pressure reaches 0.5～1.5MPa, holding down bolt is screwed out and the suitable distance of parcel thickness, and slowly pressurization then is when slow pressure reaches 2.5-3.5MPa, keep-uped pressure cooling release, the demoulding 7-12 minute.
Describe the present invention below in conjunction with accompanying drawing.
Fig. 1. plunger valve of the present invention is always schemed.
Fig. 2. the support of plunger valve of the present invention.
Fig. 3. support and fluoroplastic parcel mould adjustment figure thereof.
Fig. 4. plunger valve support fluoroplastic parcel mould device of the present invention is always schemed.
By shown in Figure 1, by valve body (1), handwheel (10), seal ring (12), plunger (3), support (4), valve rod (7), valve gaps (6) etc. constitute plunger valve of the present invention, before the fluoroplastic parcel of support (4), make plunger valve support of the present invention (4) fluoroplastic parcel mould device by Fig. 3 earlier, by patrix (19), core (20), outlet matrix (16), following die cap (12), barrel (15) Tiao Zheng And is the formations such as parts of usefulness fixedly, outlet matrix (16) is seated in the exit position of plunger valve support (4), and its shape is similar to the outlet shape.The said Tiao Zheng And fixedly parts of usefulness is holding down bolt (14), barrel bolt (18), matrix bolt (17), locating pad mould (13) etc.Utilize above-mentioned mould to be: the exit position that outlet matrix (16) is seated in plunger valve support (4) with the method for fluoroplastic parcel supports of the present invention (4), putting into barrel (15) together with support makes outlet matrix (16) and barrel (15) fastening with outlet matrix bolt (17), load onto locating pad mould (13) and following die cap (12), adjust the position of outlet matrix (16) in the support outlet, and the position of support (4) in barrel, make the gap even, transfer appropriate after, two holding down bolts (14) before and after tightening, to descend die cap (12) to unload again, take down locating pad mould (13), and then load onto down die cap (12), insert core (20), fastening barrel of And (15) and following die cap (12), the support (4) of then pressing different size adds the fluoroplastic of respective numbers in barrel (15).Load onto patrix (19), place heating equipment such as electrothermal furnace to heat entire die, till when being heated to the fluoroplastic thawing always, at this moment, the mould device that heating is finished moves on to press as suppressing on 100 t hydraulic press, when this initial pressure reaches 0.5～1.5MPa, is best with 1MPa, in time, stop to pressurize, two holding down bolts in front and back are screwed out the distance suitable with parcel thickness as 2 millimeters, continue slowly compacting then, when pressure reaches 2.5-3.5MPa, with 3MPa is best, keep-uped pressure 7-12 minute, with 10 minutes be the best, afterwards, the cooling release, the demoulding.The parcel of plunger (3), the inner lining fluoroplastics method of valve body (1) is known prior art.The valve rod of plunger valve of the present invention (7) is made up of valve rod (7), swivel nut (5), plunger (3) with the coupling mechanism of plunger (3), and swivel nut (5) is that left hand thread engagement, valve rod (7) cooperate for right-hand thread with Stem Mut (8) with plunger (3) endoporus.This coupling mechanism also can prolong the working life of plunger valve than the connecting mode of it existing valve rod and plunger.(9) be that valve gap screws bolt, (11) are the fluoroplastics lining coverings, and the resistant material of lining bag is fluoroplastic such as polychlorotrifluoroethylene, polyfluorinated ethylene plastic, polyvinylidene fluoride.
Advantage of the present invention: the plunger valve is corrosion-resistant, and prolong service life, and the fluoroplastics packaging method is feasible.
