Abstract
The invention relates to the technical field of ball valve equipment, in particular to a chlor-alkali fluoroplastic full-lining ball valve. The ball valve comprises a valve body, a valve cover arranged on the valve body, a ball body arranged in an inner cavity of the valve body, and a valve rod connected with the ball body into a whole, wherein a stuffing box is arranged outside the upper end of the valve rod; a V-shaped stuffing is arranged between the stuffing box and the valve rod; a stuffing gland is arranged on the V-shaped stuffing; and a handle is arranged above the stuffing gland, and connected with a nut at the top end of the valve rod. The ball valve adopts a ball valve part with a fluoroplastic lining, so that the ball valve has very high chemical stability, and is applicable to any high-corrosion chemical media; the ball valve is in an all-pass floating ball valve structure, and non-leakage closing is conducted within a whole pressure range, so that ball-passing pipeline cleaning of a pipeline system and pipeline maintenance are facilitated; and the start and stop piece ball body and the valve rod are integrated, so that the possibility that the valve rod is rushed out of a pressure bearing piece due to a pressure change is avoided, and the using safety and reliability are ensured completely.
Description
Technical field
The present invention relates to the ball valve equipment technical field, be specifically related to a kind of chlor-alkali fluoroplastic all-liner ball valve.
Background technique
At present, all be that the spheroid of band manhole is made open-shut device about the structural principle of ball valve, spheroid rotates to realize valve opening and the purpose of closing with valve rod around the valve body center line.Ball valve is mainly used to make cut-out, distributes and change the flow direction of medium in pipeline, it only need just can be closed tightly with revolving the operation that turn 90 degrees and very little moment of rotation.According to the structural advantage of ball valve, can be widely used in the pipe-line systems such as oil, chemical industry.But pipeline circulation mediums such as existing petrochemical industry are acid-base class, and the ball valve of prior art is had corrosivity, are conducive to damage ball valve, thereby have shortened the working life of ball valve.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in design, compact structure, utilize molding apparatus to make the Full lining ball valve more to adapt to chlor-alkali fluoroplastic all-liner ball valve in the systems such as oil, chemical industry on former basis.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: a kind of chlor-alkali fluoroplastic all-liner ball valve, comprise valve body, be located at valve gap on the described valve body, be located at the spheroid of described body cavity, be connected the valve rod of one with described spheroid, the outside, upper end of described valve rod is provided with stuffing box, be provided with the V-type filler between described stuffing box and the valve rod, described V-type filler is provided with Gland, the top of described Gland is provided with handle, and described handle is connected with the top nut of valve rod.
Further, described spheroid is fluoroplastics lining nexine spheroid.
Further, be provided with seal ring between described spheroid and the body cavity.
The present invention has following beneficial effect: a kind of chlor-alkali fluoroplastic all-liner ball valve of the present invention, at first adopt the ball valve of fluoroplastics lining nexine, has high chemical stability, be applicable to any severe corrosive chemical mediator, and all-pass floating ball valve structure, in whole pressure range, do not have to leak and close, be convenient to pipe-line system and safeguard at pipeline pigging and pipeline; Secondly open-shut device spheroid and valve rod are integral type, have stopped to go out the possibility of pressure part because the pressure variation causes valve rod, guarantee safe and reliable fully; Last circulation area is big, and body cavity space minimum has reduced the medium delay; In addition, adopt mould pressing process, make sealing surface density good, reliably guarantee sealability.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of chlor-alkali fluoroplastic all-liner ball valve, comprise valve body 1, be located at valve gap 2 on the described valve body 1, be located at the spheroid 3 of described valve body 1 inner chamber, be connected the valve rod 4 of one with described spheroid 3, the outside, upper end of described valve rod 4 is provided with stuffing box 5, be provided with V-type filler 6 between described stuffing box 5 and the valve rod 4, described V-type filler 6 is provided with Gland 7, and the top of described Gland 7 is provided with handle 8, and described handle 8 is connected with the top nut of valve rod 4; In the present embodiment, spheroid rotates to realize valve opening and the purpose of closing with valve rod around the valve body center line, ball valve is mainly used to make cut-out, distributes and change the flow direction of medium in pipeline, it only need just can be closed tightly with revolving the operation that turn 90 degrees and very little moment of rotation.
Described spheroid 3 is fluoroplastics lining nexine spheroid, and design has high chemical stability like this, is applicable to any severe corrosive chemical mediator.
Be provided with seal ring 9 between described spheroid 3 and valve body 1 inner chamber, design makes sealing surface density good like this, reliably guarantees sealability.
Explanation is at last, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, other modifications that those of ordinary skills make technological scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
