Abstract
The utility model belongs to the field of special valves for medium transportation pipelines in the chemical industry, and particularly relates to a fluorine-lined eccentric semi-ball valve. The fluorine-lined eccentric semi-ball valve comprises a valve body (1), wherein a semi-ball (3) and a valve seat (4) are arranged inside the valve body (1); and the semi-ball (3) is connected with a hand shank (7) outside the valve body through a valve rod (5). The fluorine-lined eccentric semi-ball valve is characterized in that a polytetrafluoroethylene padding (6) is arranged in a stuffing box between the valve body (1) and the valve rod (5); a lining layer is arranged at the outer surface of the valve rod (5), and the inner wall of the internal channel of the valve body (1) is completely provided with a first fluorine plastic lining (2). The fluorine plastic lining and the lining layer have super-strong stability, can be used for preventing a strong-corrosive high-risk medium from corroding the valve body, and preventing the valve rod from being damaged, so as to prolong the whole service life and ensure the normal work of the fluorine-lined eccentric semi-ball valve. The fluorine-lined eccentric semi-ball valve is small in pressure loss; liquid loss is zero when the fluorine-lined eccentric semi-ball valve is fully opened; a runner is completely smooth; and an inner cavity can be automatically cleaned, and the medium is not deposited in the valve cavity.
Description
Technical field
The utility model relates to a kind of lining fluorine eccentric half-ball valve, belongs to chemical industry medium transport pipeline special valve field.
Background technique
Eccentric half-ball valve is made up of valve body, hemisphere, valve rod, handle and valve seat filler, and hemisphere and valve seat are set in the valve body, and hemisphere and valve seat match, and hemisphere connects the outside handle of valve body through valve rod.During valve closing, hemisphere and valve seat constitute sealing state, opening type, and hemisphere turns an angle, and the pressure loss is little.
In actual use, existing eccentric half-ball valve causes corrosion easily when carrying the high-risk medium of deep-etching, and can get into Stuffing box corrosion main body and valve rod, the working life of having reduced eccentric half-ball valve along valve rod.
Summary of the invention
According to above deficiency of the prior art, the technical problem that the utility model will solve is: the lining fluorine eccentric half-ball valve that a kind of good sealing effect, long service life are provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of lining fluorine eccentric half-ball valve; Comprise by valve body; Hemisphere and valve seat are set in the valve body, and hemisphere connects the outside handle of valve body through valve rod, and it is characterized in that: the Stuffing box between valve body and the valve rod is provided with the filler of teflon; Stem exterior surface is provided with backing layer, and the valve inner vias inner walls all is provided with first fluorine and moulds lining.
Filler and stem exterior surface that Stuffing box is provided with PVF are provided with after the backing layer, can effectively improve sealing effect, prevent high-risk erosion medium resistance valve body of deep-etching and valve rod.The valve inner passage is provided with fluorine and moulds lining, can improve the valve body life-span, prevents valve body corrosion back leakage, improves the quality of fed sheet of a media.
Sealing effect and the further control accuracy that improves in order to improve lining fluorine eccentric half-ball valve, adopted following technological scheme:
Described Stuffing box inwall is provided with second fluorine and moulds lining.Prevent to corrode valve body.
The beneficial effect that the utility model had is: through the Stuffing box between valve body and the valve rod filler of teflon is set, stem exterior surface is provided with backing layer, and the valve inner passage is provided with fluorine and moulds lining; Effectively improve sealing effect; Fluorine is moulded backing layer and is had superpower stability, avoids the high-risk erosion medium resistance valve body of deep-etching, avoids valve rod to damage; Thereby prolong whole working life, guarantee the proper functioning of lining fluorine eccentric half-ball valve.Through the integrality setting, accurate control flow rate is used to realize that remote auto accurately controls.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1, valve body 2, fluorine are moulded lining 3, hemisphere 4, valve seat 5, valve rod 6, filler 7, handle.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; Hemisphere 3 and valve seat 4 are set in the valve body 1, and hemisphere 3 connects the outside handle 7 of valve body through valve rod 5, and the Stuffing box between valve body 1 and the valve rod 5 is provided with the filler 6 of teflon; Valve rod 5 outer surfaces are provided with backing layer, and valve body 1 inner passage inwall all is provided with fluorine and moulds lining 2.
The Stuffing box inwall is provided with fluorine and moulds lining.
It is that materials such as inner liner polytetrafluoroethylene, PFA, F46 form that fluorine is moulded lining 2.Backing layer is the stratiform structure that materials such as teflon, PFA, F46 form.
Working principle:
Fluorine is moulded backing layer and is had superpower stability, avoids the high-risk erosion medium resistance valve body 1 of deep-etching, avoids valve rod 5 to damage, thereby prolongs whole working life, guarantees the proper functioning of lining fluorine eccentric half-ball valve.Through the integrality setting, can also be accurate control flow rate, be used to realize that remote auto accurately controls.
On the whole, the utility model pressure loss is little, and the liquid damage is zero during standard-sized sheet, and runner is unobstructed fully, can realize that inner chamber cleans automatically, and hemisphere half-twist, medium can not stockpile in valve pocket.
Claims (2)
1. one kind serves as a contrast the fluorine eccentric half-ball valve; Comprise by valve body (1); Hemisphere (3) and valve seat (4) are set in the valve body (1), and hemisphere (3) connects the outside handle (7) of valve body through valve rod (5), and it is characterized in that: the Stuffing box between valve body (1) and the valve rod (5) is provided with the filler (6) of teflon; Valve rod (5) outer surface is provided with backing layer, and valve body (1) inner passage inwall all is provided with first fluorine and moulds lining (2).
2. lining fluorine eccentric half-ball valve according to claim 1 is characterized in that: described Stuffing box inwall is provided with second fluorine and moulds lining.
