Abstract
The utility model discloses a ball valve, which comprises a valve body, a sealed valve seat and a ball body. The ball valve is characterized in that the valve body adopts a structure consisting of the core space of a steel skeleton coated with polyperfluorinated ethylene propylene. The sealed valve seat is made of teflon and silicone rubber. The steel skeleton is coated with polyperfluorinated ethylene propylene so as to form the ball body. The outside of the sealed valve seat is provided with annular convex ribs. The ball valve with a fluoroplastic lining is excellent in anti-corrosion performance and intensity, good in sealing performance and economical, which is very suitable for being used in large-caliber anticorrosion working conditions.
Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of novel fluoroplastics lining ball valve.
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, General valve obviously can't use because receive the restriction of Korrosionsmedium for a long time, therefore in this type occasion, needs the valve of fluoroplastics lining usually.And existing fluoroplastics lining valve such as Lining Ball Valves, because of seal valve seat is the polytetrafluoroethylmaterial material structure, elasticity is not enough; Be easy to generate leakage; Its sealing still can reach requirement for small-bore ball valve, but for the heavy caliber ball valve, its sealability can't reach seal request.
The model utility content
The purpose of the utility model is the deficiency that solves existing fluoroplastics lining ball valve, thereby a kind of good seal performance, economical and practical fluoroplastics lining ball valve are provided.
The technological scheme that the utility model solution existing technology deficiency is taked is: a kind of ball valve comprises valve body, seal valve seat and spheroid.Be characterized in: described valve body is to coat the perfluoroethylene-propylene structure at steel skeleton inner chamber; Described seal valve seat is that teflon adds silicone rubber and processes; Described spheroid is to coat the perfluoroethylene-propylene structure at the steel skeleton; The described seal valve seat outside is provided with the annular convex rib design.
Further, described seal valve seat is the mixture of teflon and silicone rubber.
Further again, the convex tendon of described seal valve seat is one.
The beneficial effect of the utility model is: the utility model had both had excellent sealing performance, again because valve body is the steel skeletal structure, therefore can guarantee to have good intensity simultaneously.Fluoroplastics lining ball valve sealing valve seat after the improvement designs for annular convex rib, and the centre is added with silicone rubber as filling, and sealability improves approximately about 25% than original, and improved more than 1.5 times the working life of whole billiard ball valve.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the I place enlarged view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
The instance of the utility model ball valve as shown in Figure 1 includes valve body 1, seal valve seat 2 and spheroid 3 and forms.Described valve body 1 is to coat perfluoroethylene-propylene (FEP) structure at steel skeleton inner chamber.Described seal valve seat 2 is processed for teflon adds silicone rubber.Described spheroid 3 is to coat perfluoroethylene-propylene (FEP) structure at the steel skeleton.Therefore have extraordinary antiseptic property, and the steel skeletal structure makes then valve body, seal valve seat and spheroid have good intensity, so be very suitable for using on the bigbore working condition.
As shown in Figure 2, the described seal valve seat outside is provided with a convex tendon, and the valve that is provided with convex tendon helps the sealability of valve, and obviously, and the number of this convex tendon can be one, more than two or three.
Claims (3)
1. ball valve; Comprise valve body, seal valve seat and spheroid; It is characterized in that: described valve body is to coat the perfluoroethylene-propylene structure at steel skeleton inner chamber; Described seal valve seat is that teflon adds silicone rubber and processes, and described spheroid is to coat the perfluoroethylene-propylene structure at the steel skeleton, and the described seal valve seat outside is provided with annular convex rib.
2. ball valve according to claim 1 is characterized in that: described seal valve seat is the mixture of teflon and silicone rubber.
