Abstract
The utility model belongs to the valve field leads to the poor wear -resisting ball valve of steel lining pottery who provides of its chemistry nature and physics nature to the current main material of ball valve for the metal material. Including left valve body, right valve body, well valve body, disk seat, spheroid, valve rod, packing assembly and handle, the spheroid be ceramic spheroid, and the disk seat be ceramic disk seat, and body pottery during well valve body inner wall is equipped with all is equipped with the pottery at the inner wall of left valve body and right valve body and takes over, and two potteries are taken over and are passed through the sealing washer respectively and be connected with two ceramic valve seat seal, and two ceramic disk seats are all through sealing washer and the ceramic sealing connection of the well body, and ceramic spheroid is connected with ceramic valve seat seal. Still be equipped with between valve rod and well valve body one prevent the unexpected departure of valve rod prevent flying the cover. The utility model discloses have high stand wear and tear, resistant erosion, certain corrosion resisting property, and the thermal insulation is good, the thermal energy is little. Special prevent flying the subassembly structure, the increase prevents the possibility of valve rod departure.
Description
Technical field
The utility model belongs to valve field, particularly relates to a kind of steel lining abrasive ceramic spherical valve.
Background technique
The valve body of existing ball valve, valve seat, spheroid are metal material and make, and its chemical stability and hardness are all poor, and thermal insulation is poor, and the impact of being expanded with heat and contract with cold is comparatively large, uses and has larger narrow limitation.
Model utility content
The purpose of this utility model is for metal material causes it chemically and the defect of physical difference and a kind of steel lining abrasive ceramic spherical valve provided for the main material of existing ball valve.
The utility model is achieved by the following technical solution:
Steel lining abrasive ceramic spherical valve, comprise left valve barrel, right valve barrel, middle valve body, valve seat, spheroid, valve rod, filler assembly and handle, valve rod upper end connecting handle, valve rod lower end connects spheroid, filler assembly is located between valve rod and middle valve body, described spheroid is spheres of ceramic, valve seat is ceramic valve seat, middle valve interior wall is provided with middle body pottery, middle valve body is tightly connected respectively by seal ring and left valve barrel and right valve barrel, pottery adapter is equipped with at the inwall of left valve barrel and right valve barrel, two pottery adapters are tightly connected respectively by seal ring and two ceramic valve seats, two ceramic valve seats are all connected with middle body ceramic seal by seal ring, spheres of ceramic and ceramic valve seat are tightly connected.
Between described valve rod and middle valve body, be also provided with anti-the flying preventing valve rod from surprisingly flying out overlap, prevent flying to be placed on filler assembly lower end, prevent that flying cover is sheathed on stem exterior, valve rod is arranged with the projection that the anti-position flying to overlap is provided with a ring-type, anti-flying, cover is provided with the sunk part with this male cooperation.
Described filler assembly comprises the filler, Gland, the hold-down grid that arrange in turn from bottom to top, and filler is filled between valve rod and middle valve body, and filler lower end contacts anti-flying and overlaps, and hold-down grid upper end connects locking pressing plate.
The utility model has following beneficial effect:
1. the part of Wear-resistant ceramic ball valve and medium contact is structural ceramic material and particulate metal material, and structural ceramics chemical stability and extreme hardness (Rockwell hardness HRC88), be only second to diamond.Therefore, this valve has high wear-resistant, erosion resistance, certain decay resistance, and thermal insulation is good, and thermal expansion is little.Special anti-ly fly modular construction, prevent valve rod from flying out.
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.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
