Abstract
The utility model discloses a composite ceramic hard sealing ball valve, which comprises a valve body and a composite ceramic valve ball positioned in the valve body, wherein a valve rod connected with the valve ball is arranged on the valve body, the valve ball is connected with a connecting head through a plunger pin, and the connecting head is in radial sliding type insertion connection with the inner end part of the valve rod. Because the valve ball and the valve rod are connected through the connecting head, the connection does not belong to the hard fixed connection, the radial force of the valve rod caused by the form and position errors generated by each component after assembly can be automatically regulated through the relative micro sliding of bulges and grooves, the torque during the valve rod rotation is reduced, the abrasion of each component is lightened, the service life of the ball valve is prolonged, the labor is saved during the valve rod rotation, the self sealing performance of the ball valve is improved, the maintenance and replacement times are reduced, the operation cost is reduced, and the economic benefit is improved.
Description
Technical field
The utility model relates to a kind of ball valve, and particularly a kind of composite ceramics hard seal ball valve is mainly used in chemical industry, belongs to pipeline ball-valve.
Background technique
When utilizing pipeline to carry liquid, gas or powder in the chemical industry, on pipeline, valve must be installed, be used for control fed sheet of a media; The valve that uses in the chemical pipeline at present mainly is a ball valve, and structure is following: the valve body that has left and right sides two-part to combine has the composite ceramics valve ball of band central through bore at the inner chamber of valve body; Between valve ball and the valve body seal ring is arranged; On valve body, through valve gap and Sealing valve rod is installed, the inner termination of valve rod is connected with valve ball is rigid, and the external end head of valve rod is connected with bull stick; Two ends of valve body is respectively the gateway of fed sheet of a media, and the gateway periphery of medium is an adpting flange.Through flange ball valve is installed on the pipeline during installation; When rotating bull stick, drive valve ball through valve rod and rotate, valve ball rotates the fed sheet of a media gateway that can be communicated with the valve body two ends through central through bore; Reach the purpose that ball valve is opened, the angle of adjustment valve ball can change the size of ball valve unlatching or close.The ball valve of this structure; Owing to morpheme error in various degree can occur when each component processing and assembling, make valve rod receive the influence of different radial forces, increased torque during rotation; Each parts has wearing and tearing in various degree relatively, influences the working life and the sealing effect of ball valve.
Summary of the invention
The purpose of the utility model provides a kind of valve rod and can regulate radial clearance and radial force automatically, reduces relative wear between each parts, improve the composite ceramics hard seal ball valve in working life, overcomes the deficiency of existing technology.
The composite ceramics hard seal ball valve of the utility model; Comprise valve body and the composite ceramics valve ball that is positioned at valve body; The valve rod that joins with valve ball is installed on the valve body, and described valve ball joins through pin and connecting head, pegs graft for radially sliding formula between the inner termination of connecting head and described valve rod.
The composite ceramics hard seal ball valve of the utility model, the pin between described connecting head and the described valve ball is two, the termination of each pin insert respectively in the valve ball pin-and-hole on the valve ball with the connecting head lower end on the connecting head pin-and-hole in; There is boss the intermediate portion, upper-end surface of connecting head, and the inner termination of valve rod is provided with groove, pegs graft through boss and groove between described valve ball and the described valve rod.
The composite ceramics hard seal ball valve of the utility model owing to be connected through connecting head between valve ball and the valve rod, does not belong to rigid fixed connection; The morpheme error of each parts generation can reduce the moment of torsion when valve rod rotates through boss and groove trace slip adjusting voluntarily relatively to the radial force that valve rod produces after the assembling, and the wearing and tearing of each parts are alleviated; Prolonged the working life of ball valve; Rotation valve rod is laborsaving, and the self seal performance of ball valve increases, and the maintain and replace number of times reduces; Reduce operating cost, improved economic benefit.

Embodiment
As shown in Figure 1: valve body is made up of left valve barrel 3 and right valve barrel 10, is fixedly connected through connecting bolt, and its junction plane is provided with sealing gasket.The valve ball 1 that the band central through bore of composite ceramic material is arranged in the inboard of valve body.Left seal ring 2 is arranged between valve ball 1 and the left valve barrel 3, between left seal ring 2 and the left valve barrel 3 seal ring is arranged; Right seal ring 11 is arranged between valve ball 1 and the right valve barrel 10, between right seal ring 11 and the right valve barrel 10 seal ring is arranged.All there is the gateway of fed sheet of a media in the outside of left valve barrel 3 and right valve barrel 10, is flange in the periphery, gateway of fed sheet of a media, is connected with pipeline through flange.Valve ball 1 is rotatable in valve body, and the rotation of valve ball 1 can be communicated with the fed sheet of a media gateway at two ends, the size that the convertible ball valve of the rotation angle of valve ball 1 is opened through central through bore.Valve rod 7 is equipped with through gland 6 in top at left valve barrel 3, and the external end head of valve rod 7 connects pivoted housing 4 and is connected, and pivoted housing 4 tops are inserted with bull stick 5.Between valve rod 7 and left valve barrel 3, be provided with Sealing.
Like Fig. 1,2,3,4,5,6,7, shown in 8: the plane is arranged at the top at valve ball 1, is processed with two valve ball pin-and-holes 12 on this plane.8 is connecting head, and it is identical with the centre distance of two valve ball pin-and-holes 12 on the lower end surface of connecting head 8, to be processed with 14, two connecting head pin-and-holes 14 of two connecting head pin-and-holes, and two connecting head pin-and-holes 14 and two valve ball pin-and-holes 12 align and insert pin 9 during assembling.There is boss 13 intermediate portion, upper-end surface of connecting head 8.The inner termination of valve rod 7 is processed with the groove that matches with boss 13, and boss 13 inserts in the groove, and valve rod 7 is connected through connecting head 8 with valve ball 1.
Through flange ball valve is installed on the pipeline during installation; When rotating bull stick 5; Driving valve ball 1 through valve rod 7 rotates; Valve ball 1 rotation can be communicated with the fed sheet of a media gateway at valve body two ends through central through bore, reach the purpose that ball valve is opened, and the angle of adjustment valve ball 1 can change the size of ball valve unlatching or close.Owing to is connected through connecting head 8 between valve ball 1 and the valve rod 7, do not belong to rigid fixed connection, the radial force that the morpheme error that each parts of assembling back produce produces valve rod 7 can be through the micro-relatively slip of boss 13 and groove adjusting voluntarily; Reduce the moment of torsion when valve rod 7 rotates, the wearing and tearing of each parts are alleviated, prolonged the working life of ball valve; Rotation valve rod 7 is laborsaving, and the self seal performance of ball valve increases, and the maintain and replace number of times reduces; Reduce operating cost, improved economic benefit.
