Abstract
The utility model discloses a ball valve with height adjustable ratio which belongs to the ball valve. Because of the structure limit of the existing ball valve which is in the 'O'-shaped or the 'V' shape, the adjustable ratio is 200: 1 in common, and the highest ratio is 300: 1. In order to fulfill the requirements for high adjustable ratio of the special pipes, the ball valve with height adjustable ratio is designed. The utility model is mainly characterized in that a special hole is opened on the valve core of the ball valve, and the included angle of the axial line of valve rods and the axial line of the passage of the valve body is less than 90 DEG, increasing the adjustable ratio of the ball valve reach 500: 1. The ball valve can be used as an adjusting valve or a stop valve and has the advantages of novel structure, easy operation, high accuracy of regulation, and good property of flow quantity.
Description
The utility model belongs to a kind of ball valve.
Existing at present " O " type ball valve or " V " type ball valve are to have round on the spool in being installed in valve body or " V " type through hole.Rotary valve rod drives spool, just can change opening area, reaches the purpose of regulating flow.Its regulating ratio generally about 200:1, is 300:1 to the maximum.In some special pipe-line system, need to enlarge regulation range and satisfy the production needs.Generally be that the use in parallel of two modulating valve is installed.Make troubles so not only for installation and operation, the regulation quality of modulating valve is degenerated, the quality of influence production and product.
The purpose of this utility model is exactly a kind of ball valve with high regulating ratio to produce needs and design in order to satisfy.This ball valve is that fitting operation conveniently can improve degree of regulation again, improves regulation quality; Can make modulating valve uses with making stop valve again.
The technical solution of the utility model is achieved in that a kind of by the valve body with import and export, the ball valve that is installed in valve seat in the valve body, spool is installed on the valve body to be constituted by valve rod.Its special way is:
1, valve rod and valve channel have an inclination angle (40 °～80 °).This inclination angle is the particular via of spool and special the setting.
2, valve core through hole is a particular via.This through hole is to form like this: the maximum circular hole that through hole contains on the spool is the maximum diameter of this valve.This circular hole clockwise (or counterclockwise) on the spool spheroid, rotate an angle (maximum can reach 270 °) around valve rod axis, and in rotary course gradually diameter reduction until being zero.So just formed this particular via.Valve rod axis and valve channel axis angle are less than 90 ° (between 40 °～80 °).
The advantage of this model utility is, according to the ball valve that this technological scheme is made, regulating ratio can be up to 500:1, and the degree of regulation height, and Flow characteristics is good, easily operation.
Fig. 1 is a sectional structure chart of the present utility model.
Fig. 2 is a spool schematic representation of the present utility model.
Further specify below in conjunction with accompanying drawing:
To go up lower valve rod 1,8 is installed on the spool 4, be processed with through hole 19 on this spool 4, the maximum circular hole that this through hole contains is the maximum diameter of this valve, this circular hole rotates an angle around valve rod axis on the spool spheroid (maximum can reach 270 °, staying 90 ° does by using), in rotary course, its diameter dwindles gradually until being zero, and forms through hole 19.Axle sleeve 12,20 is installed in respectively in right valve barrel 3, the left valve barrel 2, seal ring 7,16 is installed in respectively in the seal groove of valve seat 5,17, spring 6,18, valve seat 5,17 are respectively charged in the import and outlet of right valve barrel 3 and left valve barrel 2, spool 4 is installed on left valve barrel 2, the right valve barrel 3 by valve rod 1,8.In the seal groove that is installed on the seal ring 15 on the left valve barrel 2, left and right valve body 2,3 is bound up by screw 14, valve seat 5,17 closely is pressed on the spool under the effect of spring 6,18.Seal ring 10,23 is contained on the valve gap 9,21, valve gap 9,21 is installed on the valve body by screw, stuffing box packing 13,22 is packed in the valve gap 9,22, gland 11,24 is installed on the valve gap 9,21 by screw.Rotation valve rod 1 drives the area of passage that spool 4 just can be regulated valve opening, thereby changes flow.After spool 4 turned over 270 °, the entity part of spool was blocked valve channel, was and ended, and played stop valve.
Claims (2)
1, a kind of ball valve, by valve body with import and export, be installed in valve seat in the valve body, by valve rod spool be installed on the valve body and constitute, have a through hole on the spool, it is characterized in that: the maximum circular hole that through hole contains on the spool is the maximum diameter of this valve, this circular hole rotates an angle around valve rod axis on the spool spheroid, maximum can reach 270 °, in rotary course gradually diameter reduction until being zero, and forming a particular via, valve rod axis and valve channel axis angle are less than 90 °.
2, ball valve according to claim 1 is characterized in that valve rod axis and valve channel axis have 40 °～80 ° inclination angle.
