Abstract
The utility model relates to a lining fluorine ball valve which belongs to the field of special valves for medium conveying pipelines in the chemical industry. The lining fluorine ball valve comprises a valve body, and a valve seat and a ball body arranged in the valve body, and is characterized in that the lateral and vertical sections of the ball body are square, the upper and lower ends of the ball body are smooth spherical sealing surfaces, and an annular material accumulating groove is arranged on sealed contact portions between the valve seat and the spherical sealing surfaces. In such an improved structure, the lining fluorine ball valve employs an approximate square structured ball body, so that the friction area between the square ball body and the valve seat is smaller than that between a conventional spherical ball body and the valve seat. Moreover, an annular material accumulating groove is arranged on the valve seat. The lining fluorine ball valve is simple in structure and easy for manufacture, minimizes wearing of a valve seat or a ball body, and greatly prolongs the service lifetime of the entire valve.
Description
Technical field
The utility model belongs to chemical industry medium transport pipeline special valve field, specifically is a kind of lining fluorine ball valve.
Background technique
On the transfer line of chemical industry, be directed against different purposes; Different valves all is installed; In the production or course of conveying of strong corrosive medium, also special-purpose ball valve must be installed, the Specialty Design that lining fluorine ball valve carries out for the keying of controlling various strong corrosive medias.At present, lining fluorine ball valve on the market is spherical ball, and moment of torsion is big, and the friction that causes is big, underaction when therefore opening and closing, and the sealing of ball valve is good inadequately, usually has impurity or crystalline solid to get in the ball valve, damages valve body, valve seat or spheroid.Therefore demand urgently the ball valve of this class formation is improved, to reduce the wearing and tearing of spheroid and valve body, prolong the working life of ball valve, thereby prolong the maintenance period of enterprise production equipment, reduce the cost of production of enterprise.
The model utility content
The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of simple in structure, is easy to processing, can reduce the wearing and tearing of spheroid, improves the lining fluorine ball valve of valve whole service life greatly.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme:
It is a kind of lining fluorine ball valve; Comprise valve body; And the valve seat and the spheroid that are provided with in the valve body; The present technique main points are that vertical section that laterally reaches of spheroid is square structure, and the upper end portion of this spheroid and underpart are slick and sly spherical sealing surface, and the spherical sealing surface sealing contact position of valve seat and spheroid is processed with ring-type buildup groove.
The vertical section of ring-type buildup groove on this valve seat is triangle or circular arc.
Like this when having part buildup or crystallization to produce in the valve body; Just can temporarily accumulate in the buildup groove of this valve seat; Can be with the open and close of valve action and when the Open valve once more, this part buildup or crystallization are pulled away rapidly under the washing away of flowing medium, can not cause damage to spherome surface.
The utility model is after above-mentioned improvement; Owing to adopted the spheroid of squarish structure, reduced the friction area of traditional round spherical ball and valve seat, and be processed with the buildup groove of ring-type on the valve seat; Therefore have simple in structure; Be easy to processing, can reduce the wearing and tearing of valve seat or spheroid, improve the advantage of valve whole service life greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain:
Fig. 1: the utility model example structure schematic representation.
Fig. 2: spheroid cross-sectional configuration schematic representation.
Fig. 3: the vertical cross-sectional configuration schematic representation of sealing surface of seat.
Among the figure: 1 valve body; 2 valve seats; 3 buildup grooves; 4 spheroids; 5 spherical sealing surfaces.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; This lining fluorine ball valve; Comprise valve body 1, and the valve seat 2 and the spheroid 4 that are provided with in the valve body 1, the present technique main points are that vertical section that laterally reaches of spheroid 4 is square structure; The upper end portion of this spheroid 4 and underpart are slick and sly spherical sealing surface 5, and valve seat 2 is processed with ring-type buildup groove 3 with the spherical sealing surface sealing contact position of spheroid 4.
Ring-type buildup groove 3 vertical sections on this valve seat are triangle as shown in Figure 3; Or other structures such as circular arc; Make the ring-type buildup groove 3 upper and lower two-part on the valve seat, and form upper and lower two ring bar structure double-sealings between the spherical sealing surface 5 of spheroid 4.
Like this when having part buildup or crystallization to produce in the valve body 1; Just can temporarily accumulate in this buildup groove 3; Can be with the open and close of valve action and when the Open valve once more; This part buildup or crystallization are pulled away rapidly under the washing away of flowing medium, just can not cause damage to valve seat 2 or spheroid 4 surfaces.
The utility model is after above-mentioned improvement; Owing to adopted the spheroid of squarish structure, reduced the friction area of traditional round spherical ball and valve seat, and be processed with the buildup groove of ring-type on the valve seat; Therefore have simple in structure; Be easy to processing, can reduce the wearing and tearing of spheroid, improve the advantage of valve whole service life greatly.
Claims (2)
1. one kind serves as a contrast the fluorine ball valve; Comprise valve body; And the valve seat and the spheroid that are provided with in the valve body; The vertical section that laterally reaches that it is characterized in that spheroid is square structure, and the upper end portion of this spheroid and underpart are slick and sly spherical sealing surface, and the spherical sealing surface sealing contact position of valve seat and spheroid is processed with ring-type buildup groove.
2. lining fluorine ball valve according to claim 1 is characterized in that the vertical section of ring-type buildup groove on this valve seat is triangle or circular arc.
