Abstract

The utility model discloses a novel fluorine lined ball valve which comprises a valve body, wherein the valve body is composed of a left valve block and a right valve block, a flow channel and a sphere are arranged in the valve body, and the sphere is connected with a valve stem connected with a handle through an elastic collar; packing is filled between the valve body and the valve stem through a positioning piece, a fastener and a pressing cover; the left valve block and the right valve block are mutually symmetric; and a lining is installed in the flow channel. The novel fluorine lined ball valve has the beneficial effects of practicability, low production cost and convenience in use; a separate packing box is reduced from the integral structure of the ball valve, so that the structure is simplified, and the integral structure is more compact; a packing box is directly processed on the valve body, and the separate packing box does not exist, so that sealing between the packing box and the valve does not exist, leaking points are reduced, and the sealing performance is better; and the separate packing box does not exist, so that the processing, the lining, the assembly and the like are reduced, the production efficiency is increased, and the overall cost is reduced.

Description

A kind of novel lining fluorine ball valve

Technical field

The utility model relates to a kind of ball valve, particularly a kind of novel lining fluorine ball valve.

Background technique

Existing ball valve uses independent filler substantially, complex structure, and the cost of production height, small product size is huge, and poor sealing performance, and any lining medium is not set in runner, and working life is short, damages easily.

The model utility content

Technical problem to be solved in the utility model is at the deficiencies in the prior art, and a kind of novel lining fluorine ball valve is provided.

To achieve these goals, the measure taked of the utility model:

A kind of novel lining fluorine ball valve, it is provided with runner and spheroid by the valve body that left valve piece and right valve piece are formed in the valve body, be connected with valve rod on the described spheroid, is connected with handle by circlip on the valve rod;

Be provided with filler by location piece, fastening piece and gland between described valve body and the valve rod;

Symmetrical between described left valve piece and the right valve piece;

In the described runner lining is installed.

The beneficial effects of the utility model: practicality, cost of production is low, and is easy to use, the ball valve overall structure reduces independent stuffing box, simplifies the structure thereby make, and integral body is compacter, directly process on the stuffing box valve body, do not have independent stuffing box, the sealing of stuffing box and valve has not just had, reduced by a leakage point, thereby sealability is better, does not have independent stuffing box, reduces processing, lining, assembling etc., improve manufacturing efficiency, reduced whole cost.

Embodiment

A kind of novel lining fluorine ball valve, it is provided with runner 12 and spheroid 3 by the valve body that left valve piece 1 and right valve piece 2 are formed in the valve body, be connected with valve rod 4 on the described spheroid 3, is connected with handle 10 by circlip 9 on the valve rod 4; Be provided with filler 5 by location piece 8, fastening piece 11 and gland 6 between described valve body and the valve rod 4; Symmetrical between described left valve piece 1 and the right valve piece 2; In the described runner 12 lining 7 is installed; Symmetrical between left side valve piece 1 and the right valve piece 2, make whole valve body symmetrical, symmetry center overlaps with the center of spheroid 3, and it is coaxial with valve rod 4 center lines, make two end flange be symmetrical in valve rod 4, the order ground of relative valve rod 4 symmetries, can reduce by an independent stuffing box, in addition, can be with filler 5 designs at left valve piece 1, respectively account for 1/2 circle above the right valve piece 2, the center of circle is coaxial with valve rod 4 centers, filler 5 direct Cong Zuo valve pieces 1, process on the right valve piece 2, the overall precision height is during valve opening and closing, spheroid 3 can rotate with control media and flow, thereby realizes the purpose of this utility model.

Those skilled in the art's simple change and replacement in related domain all are within the protection domain of the present utility model.
