Abstract
The utility model relates to a lining spherical valve which comprises a left valve body and a right valve body, a sealing ring, and a handle. The sealing ring is arranged at the valve seat hole of the left valve body and right valve body which are connected with a bolt, and the handle is arranged on the up end of a shanked sphere. The utility model is characterized in that the shanked sphere which is formed by a valve stem connected with the sphere as a whole is arranged in the left and the right valve, and a packing box is arranged outside the shanked sphere. The left and the right valve are lined with fuloroplastic. The utility has the advantages of good corrosion resistance, nearly resisting all chemicals including the corrosion of concentrated nitric acid and nitrohydrochloric acid, long-term use under 180 degrees centigrade, self lubricating, electric insulation, creep resistance, and non-viscosity, which meets the demands of special working condition. The utility model also has the advantages of big transmission torque force by designing the valve stem and the sphere as a whole, high intensity, safe and reliable, reducing intermediate links, forming lining easily, reducing the cost and compact structure.
Description
Technical field
The utility model relates to a kind of Lining Ball Valves, can be used for industries such as oil, chemical industry, agricultural chemicals, medicine, and medium is on the pipeline of strong acid, highly basic class corrosive fluid, and the device as opening and closing belongs to valve technology field.
Background technique
As shown in Figure 1, be former ball-valve structure schematic representation, mainly by valve body 1, seal ring 2, spheroid 3, valve rod 4, handle 5 is formed, the material of seal ring 2 is F4 material or alloy steel material, the material of valve body 1 is generally carbon steel or stainless steel, the material of spheroid 3 is that carbon steel adds two kinds of appearance chromium plating or stainless steels, seal ring 2 is put into valve body, left and right sides valve body 1 clamps spheroid 3, and valve rod 4 places in the tongue-and-groove of spheroid 3, and handle 5 is fixed on the valve rod 4 and links with bolton each other, 50～90 ° of scope activities of handle with sleeve, clockwise rotate 90 ° for closing, rotate counterclockwise 90 °, position-limit mechanism is arranged for opening.
Because carbon steel can not be applicable to the medium that corrosivity is very strong, though the corrosion of some nitric acid of stainless steel ability, acetic acid, not anti-highly basic class medium.People attempt to solve this problem with Hastelloy class material, but this class material is very expensive, and the sexual valence ratio is uneconomical.
Summary of the invention
The purpose of this utility model is the Lining Ball Valves of a kind of energy of invention strong alkali-acid resistance class material.
For realizing above purpose, the technical solution of the utility model provides a kind of Lining Ball Valves, comprise left and right sides valve body, band handle ball seal ring and handle, seal ring places in the valve seat orifice of left and right sides valve body, and left and right sides valve body connects by bolt, and handle is located at the upper end of band handle spheroid, it is characterized in that, the band handle spheroid that valve rod and spheroid fuse is located in the valve body of the left and right sides, and Stuffing box is located at band handle spheroid upper end, is provided with the lined with fluoroplastic material in the valve body of the left and right sides.
The utility model adopts the mode of mold pressing with the inwall of fluoroplastics lining to ball valve, and carbon steel is used in the outside, reduces production costs so greatly, and the advantage of fluoroplastic: corrosion resistance, temperature tolerance, non-viscosity and electrical insulating property, can strong alkali-acid resistance class material.
Advantage of the present utility model:
1. new material application fluoroplastic have superior corrosion resistance, almost can resist all chemical mediators, comprise the corrosion of red fuming nitric acid (RFNA) and chloroazotic acid, can use for a long time 180 ℃ of following temperature, also have good self lubricity, electrical insulating property, creep resistance and non-viscosity, can satisfy the requirement of special operation condition;
2. new design structure
Valve rod is become a single piece with ball design, transmitting torque power is big, intensity is high, safe and reliable, has reduced medium tache, and the lining moulding is easy, has reduced cost of production;
3. compact structure
All-pass footpath runner, pressure drop is little, is convenient to fluid and passes through, and good seal performance can reach zero leakage.
Description of drawings
Fig. 1 is former ball-valve structure schematic representation;
Fig. 2 is the Lining Ball Valves structural representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 2, be the Lining Ball Valves structural representation, described Lining Ball Valves is made up of left and right sides valve body 6, seal ring 7, band handle spheroid 8, Stuffing box 9 and handle 10.
The material of left and right sides valve body 6 adopts carbon steel, fluoroplastics lining 11 linings are gone into the inwall of valve body 6 with the mode of mold pressing, seal ring 7 is installed in the valve seat orifice of left and right sides valve body 6, to be with handle spheroid 8 to put into left and right sides valve body 6 again, connecting left and right sides valve body 6 with bolt is integral, pack into then Stuffing box 9 and filler and gland, limiting stopper, at last handle 10 is contained in the handle upper end of band handle spheroid 8, rotating band handle spheroid 8, the elasticity of adjustment bolt, handle 10 rotates in 0～90 ° of scope, position-limit mechanism is arranged, safe and reliable, favorable sealing property can guarantee zero leakage.
The utility model is mainly used on the industrial pipeline of strong acid, highly basic class medium as opening and blocking fluid usefulness, installs arbitrarily on industrial pipeline, not limited by the media flow direction, and is user-friendly.
Operating grip 10 links with band handle spheroid 8, is rotated counterclockwise 0～90 ° for opening, and turns clockwise 90～0 ° for closing, and handle part has 0～90 ° limit stoper.But standard-sized sheet, but also complete shut-down, also can become 30 ° and 60 ° of angles unlatchings, can be used as cut-off device uses, handle 10 inconvenient operation or not laborsaving can adopt worm gear drive, as adopt automatic control, the electronic gentle moving device transmission of optional usefulness is equipped with corresponding positioning work piece, advertiser and can makes far distance automatic controlling and use.
