Abstract
The utility model relates to a ball valve, especially three formula ball valves. The sealing surfaces of the left sealing ring and the right sealing ring of the ball valve are provided with a valve rod hole and a through hole, so that a spherical cavity completely surrounding the ball is formed, the radius of the spherical cavity is equal to that of the ball, and the ball is arranged in the spherical cavity in a liquid-tight and movable fit manner. Because the sealing surface of the sanitary ball valve completely wraps the ball body, when the sanitary ball valve is in a closed state, no gap or space for the medium in the ball body to leak out exists, and the medium is sealed in the ball body until the sanitary ball valve is opened next time; in addition, when the ball valve is cleaned, only clean water is introduced into the ball valve and the ball valve is opened and closed for several times, so that residues in the valve can be cleaned, and the ball valve is very convenient to use and suitable for being used in occasions or industries with higher requirements on sanitation levels.
Description
Technical field:
The utility model relates to a kind of ball valve, particularly the three pieces type ball valve.
Background technique:
The left and right seal ring of existing ball valve mostly just is an annular construction member, when riding on the spheroid, leave one section space each other, make and also have the space between spheroid and the valve body, work as ball valve like this in the opening and closing process, in the time of in off position, the medium in the spheroid can enter in the space between spheroid and the valve body inevitably, and the ball valve dismounting not to be come be to be difficult to thoroughly clean.Therefore, this ball valve is to be not suitable for using in occasion that the health rank is had relatively high expectations or industry.
Summary of the invention:
The purpose of this utility model is to provide a kind of can reach the health level ball valve that is difficult for residual fed sheet of a media and cleans easily in that higher health level requires, the valve body.
For achieving the above object, the technical solution that the utility model adopted is as follows: health level ball valve still comprises left valve gap, right valve gap, valve body, spheroid, left side seal ring, right seal ring, handle and Gland, be equipped with the through hole that passes through for medium on the seal ring of the left and right sides and become closed ring around this through hole, surface and the suitable annular sealing surface of spherome surface, seal ring is respectively from a left side, right both sides ride on the spheroid, and by a left side, right valve gap compresses, it is characterized in that: described left seal ring, the sealing surface of right seal ring is except that leaving valve rod hole and through hole, form a sphere shape chamber that fully spheroid is surrounded, the radius in sphere shape chamber equals the radius of spheroid, and spheroid liquid thickly is arranged on wherein movingly.
Because the sealing surface of health level ball valve of the present utility model wraps up spheroid fully, therefore in off position the time, there are not the gap or the space that can leak outside for the medium in the spheroid, medium will be sealed in the spheroid and open until next time; In addition, only need during cleaning in ball valve, to feed clear water and carry out opening and closing several times, residue in the valve can be cleaned up, very convenient, be adapted at using in occasion that the health rank has relatively high expectations or the industry.
The utility model is described in further detail below in conjunction with accompanying drawing:
Description of drawings:
Accompanying drawing 1 is the utility model example structure sectional view.
Specific embodiment: as shown in Figure 1, health level ball valve comprises left valve gap 5 equally, right valve gap 6, valve body 4, spheroid 3, left side seal ring 1, right seal ring 2, handle 7 and Gland 8, wherein left seal ring 1, the diameter of section of right seal ring 2 and one-tenth identical with valve body 4 intracavity diameters movingly, the axial length of valve bodies 4 such as axial length sum, left side seal ring 1, right seal ring 2 shape chambeies are relative, respectively from a left side, right both sides ride over and form a sphere shape chamber on the spheroid 3 spheroid 3 is wrapped up fully, upper center is provided with the valve rod hole that enters for valve rod 9, two outsides are respectively by left valve gap 5, right valve gap 6 compresses, and fixing by four that are arranged on four jiaos bolt 10 and the nuts 11 that run through valve gap and valve body, swivel nut 11 can regulate pretightening forces.
Claims (2)
1, a kind of health level ball valve, comprise left valve gap, right valve gap, valve body, spheroid, left side seal ring, right seal ring, handle and Gland, be equipped with the through hole that passes through for medium on the seal ring of the left and right sides and become closed ring around this through hole, surface and the suitable annular sealing surface of spherome surface, seal ring is respectively from a left side, right both sides ride on the spheroid, and by a left side, right valve gap compresses, it is characterized in that: described left seal ring (1), the sealing surface of right seal ring (2) is except that leaving valve rod hole and through hole, form a sphere shape chamber that fully spheroid is surrounded, the radius in sphere shape chamber equals the radius of spheroid (3), and spheroid (3) liquid thickly is arranged on wherein movingly.
2, health level ball valve according to claim 1 is characterized in that: described left seal ring (1), right seal ring (2) shape are symmetrical.
