Abstract
The utility model discloses a plunger hydraulic cylinder for a copper ingot melting-refining furnace, comprising a cylinder body, a plunger, a gland bush and a guide sleeve, wherein, the guide sleeve also comprises two Y-shaped sealing rings and two O-shaped sealing rings, which are used for sealing the cylinder body; a polyfluortetraethylene guiding support ring is also respectively arranged on both ends of the guide sleeve and used for guidance and support. By adoption of the technical proposal of the utility model, a sealing device of the plunger hydraulic cylinder is convenient for assembly, and the sealing performance is improved.
Description
Technical field
The utility model relates to a kind of copper ingot smelting furnace plunger type cylinder.
Background technique
Core melting furnace turndown is arranged mainly by two plunger type cylinder controls.Fig. 1 is the cross-sectional view of plunger type cylinder in the prior art.As shown in Figure 1, plunger type cylinder comprises cylinder body 11, plunger 12 and seal arrangement 13, and inferior part of the cylinder block has an oil inlet and outlet, when pressure oil input cylinder body, the plunger jack-up body of heater that moves upward is when pressure oil flows back to fuel tank, under the body of heater action of gravity, plunger moves downward.Seal arrangement comprises guide pin bushing 14 and gland 15, and gland is made of carbon steel, and endoporus is pressed into the guide pin bushing that the QAL9-4 wear-resistant metal material is made, and coupled columns is filled in the row guiding.Though make guide pin bushing with wear-resistant metal material, material economy, the processing technology complexity, the thin difficult processing of wall, after the endoporus wearing and tearing, maintenance is difficulty; And guide pin bushing is installed in the gland, pressured lid and cylinder body spiral marking connection location, and installation is wasted time and energy, if gland is fastening not in place, guide pin bushing slides, and does not have seal action.Seal element is many in addition, and leakage point is many, and it is unreasonable that wear-resisting guide pin bushing top and gland bottom are provided with ○Xing Mifengquan; The hydraulic cylinder works environment is abominable, and the body of heater ambient temperature lost efficacy seal ring up to 300 ℃; Guide pin bushing endoporus serious wear causes pressure oil to leak into gland from endoporus.
The model utility content
The purpose of this utility model is to propose a kind of copper ingot smelting furnace plunger type cylinder, and is easy for installation, good seal performance.
For reaching this purpose, the utility model by the following technical solutions:
A kind of copper ingot smelting furnace plunger type cylinder, comprise cylinder body, plunger, gland and guide pin bushing, described guide pin bushing also comprises twice y-shaped ring and twice ○Xing Mifengquan, is used for the sealing of described cylinder body, the two ends of described guide pin bushing also comprise one polytetrafluorethyleguide guide ring respectively, are used for guiding and support.
The inner dust ring of installing of described gland.
Described twice y-shaped ring is positioned at the inboard of described guide pin bushing, and described twice ○Xing Mifengquan is positioned at the outside of described guide pin bushing.
Described guide pin bushing is the carbon steel guide pin bushing.
According to the shoulder location, the front end of described guide pin bushing utilizes being threaded of gland and cylinder body to compress to described guide pin bushing in described cylinder body.
Described y-shaped ring is the teflon y-shaped ring.
Adopt the technical solution of the utility model, made the seal arrangement of plunger type cylinder be convenient to install, improved sealability.
Description of drawings
Fig. 1 is the cross-sectional view of plunger type cylinder in the prior art;
Fig. 2 is the cross-sectional view of plunger type cylinder in the utility model embodiment.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
Fig. 2 is the cross-sectional view of plunger type cylinder in this embodiment.As shown in Figure 2, plunger type cylinder comprises cylinder body 21, plunger 22, gland 23 and guide pin bushing 24, this guide pin bushing is the carbon steel guide pin bushing, the installed inside that contacts with plunger at guide pin bushing has twice y-shaped ring 25, this y-shaped ring is the teflon y-shaped ring, can high temperature resistantly reach 350 ℃, the outside that contacts with cylinder body at guide pin bushing is equipped with twice ○Xing Mifengquan 26, twice teflon guiding support ring 27 is installed at the two ends up and down of the inboard that contacts with plunger of guide pin bushing, is used for guiding and supports.In the gland inboard dust ring 28 is installed also one, is used for seal ring is protected.
Be nonmetal the contact between this design plunger and the guide pin bushing, surface friction drag is little, and is wear-resisting, and the life-span is long; Guiding support ring groove processing is simple, and after wearing and tearing, it is convenient that the guiding support ring is changed; By the shoulder location, the location is accurate in cylinder body for guide pin bushing, and pressured lid of front end and cylinder body spiral marking connection compress.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with the people of this technology in the disclosed technical scope of the utility model; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
