Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

With reference to attached drawing：This ball valve valve body moulding is flowed including the runner 1-1 on valve body 1, valve body 1 and for closing The spool 2 of the 1-1 in road, the both sides of spool 2 are designed with the valve seat 3 being mounted on valve body 1, stent 4, stent 4 are fixed on valve body 1 On be fixed with support plate 4-1, the valve rod 5 for being pierced by support plate 4-1 on 2 top surface of spool is installed, circular arc is fixed on support plate 4-1 Guide rail 6 is equipped with sliding block 7 on arc guide rail 6, and montant 8 is fixed on sliding block 7, and the outside of montant 8 is equipped with lateral bull stick 9, montant 8 top is fixed on lateral bull stick 9, and outer end and the 5 top vertical configuration of valve rod of lateral bull stick 9 are fixed together.

One 9-1 of threaded hole is provided on lateral bull stick 9, screw rod 1 is threaded on one 9-1 of threaded hole, screw rod 1 Outer end is fixed with turns block 1 more than one 9-1 of threaded hole, and two 10-1 of threaded hole being in communication with the outside is provided on screw rod 1, Screw rod 2 18 is threaded on two 10-1 of threaded hole, the outer end of screw rod 2 18 is fixed with section more than two 10-1's of threaded hole Turn block 2 19.

Two valve seats 3 are all plugged on valve body 1, are fitted with pressing towards what 2 direction of spool pressed for valve seat 3 on valve body 1 Spring 13 is equipped with one group of filling liquid expanding bag 1 on valve body 1, mounting blocks 4-2 is fixed on stent 4, is installed on mounting blocks 4-2 There is filling liquid expanding bag 2 15, the sliding clamp 16 for pressing filling liquid expanding bag 2 15, sliding clamp are installed on mounting blocks 4-2 Resetting spring 20 between 16 and mounting blocks 4-2 is installed, is threaded with screw rod 3 17 on stent 4, the position of screw rod 3 17 with The location matches of sliding clamp 16, the outer end of screw rod 3 17 are fixed with rotation handle 17-1, and each filling liquid expanding bag 1 is with filling Between liquid expanding bag 2 15 tubule connect, when screw rod 17 presses sliding clamp 16 and presses filling liquid expanding bag 2 15, filling liquid it is swollen Swollen bag 2 15 is compressed and expands filling liquid expanding bag 1 and each valve seat 3 is driven to be detached from the contact with spool 2.

The operation principle of the utility model：When needing that spool 2 is carried out blocking runner 1-1, using rotating handle 17-1 Screw rod 3 17 is driven to rotate and presses filling liquid expanding bag 2 15, compresses so as to which filling liquid expanding bag 2 15 is pressurized and makes to fill using liquid Liquid expanding bag 1 expands, and so as to which valve seat 3 be driven to be detached from spool 2, then, screw rod 1 is screwed out at compression bar, screw rod two 18 rotate at screw rod 1, and in rotation screw rod 2 18, spool 2 is rotated so as to convenient, after rotation is good, unscrews spiral shell Bar 3 17, so as to be resetted using pressing spring 13 and press valve seat 3, filling liquid expanding bag 1 is pressurized compression and the liquid squeezed out Body is flow back at filling liquid expanding bag 2 15, so as to complete unlatching (as shown in Figure 3) of the spool 2 to runner 1-1；To runner 1-1 Closure use identical principle, this mode not only laborsaving can open and close, but also due to spool 2 no ball valve for a long time When rotation, valve seat 3 is to disengage with spool 2, so the wear-resisting enclosed material on valve seat 2 will not be caused to wear, so as to The service life of ball valve can be greatly increased, is worthy of popularization.

Although the utility model is shown and described by reference to preferred embodiment, this profession is common Technical staff can make various variation in form and details it is to be appreciated that in the range of claims.
