Abstract
The utility model discloses a fluoroplastic lining telescopic ball valve, comprising a left valve body, a right valve body, a valve seat, a ball body, and a telescopic flange, the fluoroplastic lining telescopic ball valve is characterized in that, overflowing parts of the left valve body and the right valve body are respectively formed by fluorinated ethylene propylene coated in the internal of a steel framework, the valve seat is formed by injection molding of polytetrafluoroethylene, overflowing parts of the ball body and the telescopic flange are respectively formed by fluorinated ethylene propylene coated at the external of a steel framework, the right valve body and the telescopic flange are a separated structure. The fluoroplastic lining telescopic ball valve is advantaged by good compensation performance, good anticorrosion performance, good strength, good sealing performance, economy, and great suitability for use under large-caliber and anticorrosive working conditions.
Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to the flexible ball valve of a kind of fluoroplastics lining.
Background technique
In the occasion that heavy chemical industry, large chemical fertilizer, petroleum and petrochemical industry, smelting iron and steel etc. are carried the active sulfur body medium, metal valve obviously can't be used because can corrode for a long time; In addition, existing ball valve, because its structural reason, no Telescopic can not regulation structure length during installation, thereby can't reach the requirement of compensation, the purchase compensation device has improved purchase cost in addition.
The model utility content
The purpose of the utility model is the deficiency that solves existing ball valve, thereby provides the fluoroplastics lining that a kind of compensation performance is good, economical and practical, corrosion resistance is high flexible ball valve.
The utility model solves the technological scheme that the existing technology deficiency takes: a kind of fluoroplastics lining ball valve that stretches; Include left valve barrel, right valve barrel, valve seat, spheroid and creeping flange; It is characterized in that: the overcurrent position of described left valve barrel, right valve barrel is to coat perfluoroethylene-propylene in the steel skeleton to process; Described valve seat is that the polytetrafluoroethyl-ne propylene is injection molded, and the overcurrent position of described spheroid, creeping flange is that the steel skeleton coats perfluoroethylene-propylene outward and processes, and described right valve barrel and creeping flange are separate type; Make this ball valve have the good compensation performance, and flange can be changed easily.
The separate type place of described right valve barrel and creeping flange, the full perfluoroethylene-propylene that coats outside the steel skeleton.
The slit at the separate type place of described right valve barrel and creeping flange is by annular packing and Gland sealing.
The beneficial effect of the utility model is: the utility model corrosion resistance is high; Both had the good compensation performance; Be provided with the steel skeletal structure in left valve barrel and the right valve barrel simultaneously, therefore can guarantee to have good intensity, can change owing to telescopic flange again simultaneously; Therefore can respond the energy-conservation call of country, reduce user's purchase cost about 45%～65%.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the I portion enlarged view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
The instance of the flexible ball valve of a kind of fluoroplastics lining as shown in Figure 1 includes left valve barrel 1, right valve barrel 2, valve seat 3, spheroid 4, creeping flange 5 compositions.Described left valve barrel 1 overcurrent position is to coat perfluoroethylene-propylene (FEP) in the steel skeleton to process.Described right valve barrel 2 overcurrent positions are that the full perfluoroethylene-propylene (FEP) that coats is processed in the steel skeleton.Described valve seat 3 is injection molded for polytetrafluoroethylene (PTFE). and described spheroid 4 overcurrent positions are that the outer full perfluoroethylene-propylene (FEP) that coats of steel skeleton is processed.Described creeping flange 5 overcurrent positions are that the steel skeleton coats perfluoroethylene-propylene (FEP) outward and processes.Therefore have extraordinary antiseptic property, be very suitable for using on the bigbore etch-proof working condition.
As shown in Figure 2; Described right valve barrel and creeping flange are separate type, have annular packing 6 to fill between right valve barrel and the creeping flange matching gap, and through Gland 7 sealings; Help valve and when compensation, can not produce leakage, and flange can be changed easily.And obviously, the number of this filler also can be more than 2 or 3.
Claims (3)
1. the flexible ball valve of a fluoroplastics lining; Include left valve barrel, right valve barrel, valve seat, spheroid and creeping flange; It is characterized in that: the overcurrent position of described left valve barrel, right valve barrel is to coat perfluoroethylene-propylene in the steel skeleton to process; Described valve seat is that the polytetrafluoroethyl-ne propylene is injection molded, and the overcurrent position of described spheroid, creeping flange is that the steel skeleton coats perfluoroethylene-propylene outward and processes, and described right valve barrel and creeping flange are separate type.
2. the fluoroplastics lining according to claim 1 ball valve that stretches is characterized in that: the separate type place of described right valve barrel and creeping flange, the full perfluoroethylene-propylene that coats outside the steel skeleton.
3. the fluoroplastics lining according to claim 1 ball valve that stretches is characterized in that: the slit at the separate type place of described right valve barrel and creeping flange is by annular packing and Gland sealing.
