Abstract
The utility model discloses a two-body type ball valve used for a pipeline, which comprises a valve body. The two-body type ball valve is characterized in that the valve body is formed by connecting a left valve body and a right valve body; a valve seat and a valve element are arranged in a valve cavity formed by the left valve body and the right valve body, the valve element is matched and arranged on the valve seat, and one end of a valve rod is connected to the valve element; the connecting part of the valve element and the valve rod is provided with a balancing hole; the connecting part of the lower end of the valve rod and the right valve body is provided with a valve rod boss, and the diameter of the valve rod boss is larger than the diameter of the valve rod; and the valve rod boss is matched and arranged in a valve rod cavity on the right valve body. According to the two-body type ball valve used for the pipeline, the boss of the valve rod is limited in a hole of the right valve body, so that the valve rod can be completely prevented from flying out of the valve body, and safety accidents caused by the valve rod flying out of the valve body are stopped; and because the valve body is formed by connecting the left valve body and the right valve body, the two-body ball valve is convenient to mount and dismount.
Description
Technical field
The utility model relates to the pipeline gate valve of a kind of gas, liquid (fluid), and especially diad formula pipeline is used ball valve.
Background technique
In the conveyance conduit of gas, liquid (fluid); A plurality of valves all will be set to be controlled; The unlatching of controlling plumbing fixtures, close or the size of opening degree etc.; To produce corresponding action, the degree that makes pipeline open and control unlatching is as required perhaps closed, and makes gas, liquid (fluid) etc. pass through control valve.The ball valve of existing technology, complex structure mostly, the sealing configuration component of employing are more, sealing effect is undesirable, has leakage phenomenon; And, install, dismantle inconvenient, cumbersome; Also have, when hydrodynamic pressure was big, valve rod flew out from valve body, formed security incident or a potential safety hazard, can not adapt to the needs of pipeline control.
Summary of the invention
The utility model is undesirable to existing technology Ball valve of pipeline complex structure, sealing effect, valve rod flies out from valve body easily produces above-mentioned deficiency such as security incident, provide a kind of simple in structure, sealing effect is desirable, prevent that the diad formula pipeline that valve rod flies out from valve body from using ball valve.
The technological scheme of the utility model: diad formula pipeline is used ball valve, comprises valve body; It is characterized in that: said valve body is connected and composed by left valve barrel and right valve barrel; In the valve pocket of left valve barrel and right valve barrel formation, be provided with valve seat and spool, the spool cooperation is installed on the valve seat, and an end of valve rod is connected on the spool; In spool and valve rod joint, also offer equalizing orifice; At the lower end of valve rod and the connection part of right valve barrel, the valve rod boss is set, the diameter of valve rod boss is greater than the diameter of valve rod, and the valve rod boss is equipped with in the valve-rod cavity on right valve barrel.
Further during characteristic: said spool is a semi-spherical shape.
Valve rod is connected the center symmetrical position of spool.
The diad formula pipeline of the utility model is used ball valve, with respect to existing technology, has following characteristics:
1, the boss of valve rod is limited in the hole of right valve barrel, prevents that fully valve rod from flying out from valve body, stops
The security incident that valve rod flies out from valve body and produces.
2, connect and compose by left and right two valve bodies, install, dismantle easily.
3, simple in structure, the used component of sealing configuration are less, and sealing effect is still better.
Description of drawings
Fig. 1 is the utility model modulating valve structure sectional view.
Embodiment
In Fig. 1, the diad formula pipeline of the utility model is used ball valve, comprises valve body 1, and said valve body 1 is connected and composed by left valve barrel 2 and right valve barrel 3, detachably is to connect through bolt normally; In the valve pocket 4 that left valve barrel 2 and right valve barrel 3 constitute, be provided with valve seat 5 and spool 6, spool 6 cooperations are installed on the valve seat 5, and spool 6 is semi-spherical shape; One end of valve rod 7 is connected on the spool 6, and valve rod 7 drives spool 6 and in valve pocket 4, rotates, usually in order to rotate conveniently; And the deviation that do not rotate, valve rod 7 is connected the center symmetrical position of spool 6, in spool 6 and valve rod 7 joints; Also offering equalizing orifice 8 links to each other with valve pocket 4; So that the upper and lower end of valve rod 7 can all contact with fluid,, be convenient to rotate (reducing the resistance when rotating) with the balance that keep-ups pressure.In the lower end of valve rod 7, promptly, valve rod boss 9 is set with the connection part of right valve barrel 3, the diameter of valve rod boss 9 protrudes from the outer surface of valve rod 7 greater than the diameter of valve rod 7; Valve rod boss 9 is equipped with in the valve-rod cavity 10 on right valve barrel 3, by the inner chamber restriction than minor diameter above the valve-rod cavity 10, can not up pass through from valve-rod cavity 10, has just stopped valve rod 7 and from valve body (right valve barrel 3), has flown out.
Valve rod 7 is provided with stuffing box packing 11, is provided with Gland 12 above the stuffing box packing 11, and Gland 12 is connected with valve body 1; Be to be connected with right valve barrel 3 among the figure through bolt.
The diad formula pipeline of the utility model is used ball valve, and the flange through valve body 1 two ends is connected with pipeline.The upper end of valve rod 7 is connected with actuator; Like cylinder etc., drive valve rod 7 and rotate, valve rod 7 drives spools 6 and rotates synchronously; The spool 6 of semi-spherical shape produces the slit gradually or closes this slit gradually when rotating and between the valve pocket 4, play the effect that opens or closes valve pocket 4.
Need to prove at last; Above embodiment is only in order to technological scheme but not the restriction technologies scheme of explanation the utility model; Although the claimant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those technological schemes to the utility model make amendment or be equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.
