Abstract
The utility model discloses a to present ball valve and medium the contact not good and steel lining fluoroplastics pottery ball valve that provides of corrosion resistance and wear resistance partly. Including valve body, valve gap, valve rod, ceramic spheroid and ceramic disk seat, all be equipped with the corrosion -resistant layer that ceramic material made at inner wall and the valve gap inner wall of valve body, still include the packing box of locating between the clearance that valve rod and valve body be connected, it has the filler to fill between the clearance between packing box and the valve rod, is equipped with the gland who compresses tightly the filler on the clearance of valve rod and packing box, gland and packing box fixed connection. The packing box has ceramic material to make anticorrosive wearing layer with the face of valve body contact surface and packing box and filler contact is all compound, lies in to be equipped with the anticorrosive wearing layer that ceramic material made with filler contact segment and following outside on the valve rod. The utility model discloses be ceramic material with the part design possible and the medium contact of this valve, make the utility model discloses have extremely strong corrosion resistance and wearability.
Description
Technical field
The utility model belongs to valve field, particularly relates to a kind of steel lining fluorine plastic ceramic ball valve.
Background technique
The part of existing ball valve and medium contact is metal or plastic material, and it is both unhygienic also affects its working life, easily weares and teares.
Model utility content
The purpose of this utility model is a kind of steel lining fluorine plastic ceramic ball valve that metal or plastic material cause valve corrosion resistance and wear-resisting property not good and provide for existing ball valve and medium contact part.
The utility model is achieved by the following technical solution:
Steel lining fluorine plastic ceramic ball valve, comprise the valve body of metal ceramic lined with fluoroplastic material, valve gap and valve rod, also comprise spheres of ceramic and ceramic valve seat, the anti-corrosion layer that stupalith makes is provided with at the inwall of valve body, the anti-corrosion layer that stupalith makes is provided with at valve gap inwall, also comprise a stuffing box, stuffing box is located between the gap that valve rod is connected with valve body, filler is filled with between gap between stuffing box and valve rod, be provided with in the upper end, gap of valve rod and stuffing box the Gland compressing filler, described Gland is fixedly connected with stuffing box.
The face that described stuffing box and valve body contact face and stuffing box contact with filler is all compounded with ceramic material and makes anticorrosion antiwear layer, valve rod is positioned to contact part and following outside with filler and be provided with the anticorrosion antiwear layer that stupalith makes.
A ledge structure is equipped with at described valve interior wall and valve gap inwall, ceramic valve seat is connected to two ledge structure places, and be equipped with at least one annular groove in the outer end of valve body and valve gap, the all outside end face of anti-corrosion layer that the stupalith of valve body and valve gap is made extends, and is provided with the bulge loop with the clamping of annular groove phase in extension part.
The beneficial effects of the utility model: the utility model structure is simple, by this valve likely with the part of medium contact and need the part of moving all to be designed to ceramic material, make the utility model have extremely strong corrosion resistance and wear resistance, working life is high.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment
As shown in Figure 1, steel lining fluorine plastic ceramic ball valve, comprise the valve body 1 of metal ceramic lined with fluoroplastic material, valve gap 2 and valve rod 3, also comprise spheres of ceramic 4 and ceramic valve seat 5, the anti-corrosion layer that stupalith makes is provided with at the inwall of valve body 1, the anti-corrosion layer that stupalith makes is provided with at valve gap 2 inwall, also comprise a stuffing box 6, stuffing box 6 is located between the gap that valve rod 3 is connected with valve body 1, filler 7 is filled with between gap between stuffing box 6 and valve rod 3, the Gland 8 compressing filler is provided with at valve rod 3 and the upper end, gap of stuffing box 6, described Gland 8 is fixedly connected with stuffing box 6.
The face that described stuffing box 6 and valve body contact face and stuffing box contact with filler is all compounded with ceramic material and makes anticorrosion antiwear layer, and valve rod 3 is positioned at the anticorrosion antiwear layer being provided with stupalith with filler contact segment and following outside and making.
A ledge structure is equipped with at described valve body 1 inwall and valve gap 2 inwall, ceramic valve seat is connected to two ledge structure places, and be equipped with at least one annular groove in the outer end of valve body and valve gap, the all outside end face of anti-corrosion layer that the stupalith of valve body and valve gap is made extends, and is provided with the bulge loop 9 with the clamping of annular groove phase in extension part.Annular groove and the design of bulge loop are to allow the steel lining body of stupalith and valve body and valve gap or plastics better coordinate, both difficult drop-offs, longer service life.
The utility model main feature have following some:
1, steel lining fluorine plastic ceramic ball valve combines the advantage of lined with fluoroplastic pellet valve and ceramic ball valve, and the part of itself and medium contact is structural ceramic material and fluoroplastic, and this valve has high wear-resistant, high-corrosion resistance.
2, spheroid adopts advanced grinding equipment and manufacture technics, and ball circularity precision is high, and surface quality is good, with valve seat to after grinding, utilizes the self lubricity of structural ceramics, has good sealability.Revolutionize that metal hard-sealing ball valve easily leaks, moment of torsion is large, the not corrosion resistant shortcoming of sealing surface.
3, ceramic valve seat, spheroid have good wear resistance, and make this valve durable in use, reliability is high, long service life, are titanium alloy valve and Monel valve 2 ~ 4 times.
4, this valve is applicable to the granule medium of high hardness, or has and the medium pipeline of soft particle is used as open and close.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, simple change and the replacement of those ordinary skill in the art are all within protection domain of the present utility model.
