Abstract
The utility model relates to a double eccentric full-path ball valve, which comprises a valve body, a valve seat and a ball body, wherein, the valve body is composed of a left half segment and a right half of the valve body which is provided with a liquid flow path; a valve seat is arranged at an opening of the fluid flow path of an inner ring of the left half segment of the valve body; a lug boss on the outer side wall of the flow path a ball body which is arranged in the right half segment of the valve body by an upper valve rod and a lower valve rod is a sealing surface. The utility model has the advantages of simple structure, less manufacturing materials, low cost, light abrasion for opening and closing, long service life and easy mechanical processing.
Description
The utility model relates to a kind of fluid delivery pipeline and cuts off element, particularly a kind of two eccentric whole-through diameter ball valves.
At present, widely used pipeline cuts off element and mostly is ball valve in fluid delivery pipeline, its cost height, and since spheroid and valve seat all the time tight connecting contact, have the deficiency of opened/closed serious wear.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and offers the light two eccentric whole-through diameter ball valve of the low and opened/closed of a kind of cost of fluid delivery pipeline wearing and tearing.
The purpose of this utility model can realize by such technological scheme: the two eccentric whole-through diameter ball valve that the wearing and tearing of the low and opened/closed of this cost are light, it comprises that a valve body left side half that is provided with fluid course lacks and be provided with the right valve body that constitutes that partly lacks of valve body of fluid course, the valve seat that circulation body runner mouth was provided with in a valve body left side half lacked, be the spheroid of sealing surface by the boss with on the spheroid runner outer side wall of valve stem equipment up and down in valve body right half lacks, " centre of sphere " of the relative spheroid in lower valve rod center has two equidistant offset A on it on pipeline axis and vertical duct axial direction, valve body " centre of sphere " also has an offset A relatively.Two eccentric whole-through diameter ball valve like this, when its valve rod counterclockwise rotated, the ball seal face promptly broke away from valve seat under the effect of off-centre, and along with the rotation of valve rod is opened fully; When clockwise direction rotates, can close, and under the effect of off-centre, realize the sealing that compresses of ball seal face and valve seat.
This two eccentric whole-through diameter ball valves provided by the utility model have following advantage: 1, simple in structure, manufacturing is few with material, cost is low, 2, opened/closed light abrasion, life-span be long, 3, machining is easy.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail:
The internal structure schematic representation of two eccentric whole-through diameter ball valves that Fig. 1 is provided for the utility model embodiment.
Fig. 2 is the B-B sectional view of Fig. 1.
With reference to accompanying drawing, the utility model embodiment is provided this two eccentric whole-through diameter ball valves, it comprise a valve body left side half that is provided with fluid course lack 1 and the valve body right half that is provided with fluid course lack the section that 2 valve bodies that constitute, a valve body left side half lack circulation body runner mouth setting in 1 be "
" seal ring 12 that is provided with by caulking groove on the elastic seat 11 of shape and the elastic seat 11; it is the spheroid 3 of sealing surface that valve body right half lacks the boss with on the spheroid runner outer side wall that install by last lower valve rod (4,5) in 2, and " centre of sphere " O ' of the relative spheroid 3 of (4, the 5) center O of lower valve rod on it has two equidistant offset A, relative valve body " centre of sphere " O ' that an offset A is also arranged on pipeline axis and vertical duct axial direction.
Among the figure, 6---the upper valve rod end cap, 7---the lower valve rod end cap, 8---upper stem seal Circle, 9---the upper valve rod bearing, 10---the seal washer that arranges between partly lacking about valve body, 13---the lower valve rod bearing, 14---the lower stem seal circle.
Claims (2)
1, a kind of two eccentric whole-through diameter ball valve, it is characterized in that: it is to be lacked (1) and be provided with the valve body that right half scarce (2) of valve body of fluid course constitute by a valve body left side that is provided with fluid course half, a valve body left side half lacks the valve seat (11) that (1) interior circulation body runner mouth is provided with, valve body right half lacks in (2) by last lower valve rod (4,5) Zhuan Zhi the boss with on the spheroid runner outer side wall is spheroid (3) formation of sealing surface, and lower valve rod (4 on it, 5) " centre of sphere " O ' of the relative spheroid of center O (3) has two equidistant offset A on pipeline axis and vertical duct axial direction, relative valve body " centre of sphere " O " an offset A also arranged.
2, two eccentric whole-through diameter ball valve according to claim 1 is characterized in that: the valve seat (11) that a valve body left side half lacks the setting of (1) interior circulation body runner mouth for section be "
" elastic seat of shape, be provided with seal ring (12) by caulking groove on it.
