Description

A kind of ball-cock assembly preventing displacement

Technical field:

The utility model relates to a kind of valves.

Background technique:

Existing ball-cock assembly or as disclosed in patent 03259822.X is consolidated by be arranged in that valve body two sides blow out Determine ear ball-cock assembly is fixed on water tank, such mounting structure, when water tank space is limited, the fixed ear that two sides are blown out just is interfered The installation of ball-cock assembly causes ball-cock assembly that cannot be mounted in water tank；When being mounted on water tank, it is limited to be particularly wall-mounted on space Water tank in when, be by by the thread pipe joint being pierced by water tank outside water tank and the spiral shell being screwed on thread pipe joint Ball-cock assembly is fixed in water tank by mother, since being screwed on for nut is fixed on outside water tank, it is arranged and fixed conveniently, not by narrow The restriction in the space in narrow water tank, such fixed structure are what there is no problem in stationary state, still, due to positive reason Under condition, assembly is different the steam production plants of water tank (such as with) with using position, generally require transportational process will assemble it is floating The water tank of ball valve, which transports, to be used on position, and being jolted in transportational process by carrying is influenced, the position of the ball-cock assembly in water tank It is easy displacement, to affect the normal work of ball-cock assembly.

Utility model content:

The purpose of the invention of the present invention is to provide one kind can use in the water tank of narrow space, meanwhile, and energy When preventing carrying from jolting, what the position of ball-cock assembly will not shift prevents the ball-cock assembly of displacement.

The utility model is realized in this way the spool movement including valve body, driving valve body with thread pipe joint Floating ball driving mechanism, thread pipe joint have fixture nut, primary seal washer, its special feature is that thread pipe joint It is provided on valve body at root with for wearing the ear for connecing the perforation of screw rod, ear is located at the top of floating ball driving mechanism, ear It is close on that side of water tank and is provided with time gasket.

In use, passing through the thread pipe joint of tank ball-float valve connection perforation by fixture nut, primary seal washer It is fixed on water tank, so that ball-cock assembly is fixed in water tank, primary seal washer is between valve body and water tank, to prevent water from valve Clearance leakage between body, water tank, then, screw rod sequentially pass through ear, secondary gasket, tank ball-float valve and connect the small perforation on perforating Afterwards, ear is fixed on water tank by the primary nut being screwed on screw rod outside water tank, in this way, during transportation, due to there is ear Positioning action, even if carry jolt, thread pipe joint will not rotate, and ball-cock assembly is caused to shift.

Here, primary seal washer, the connection of secondary gasket are integral, in this way, not only improving sealing, while being conducive to give birth to again It produces and installs and uses.

Here, floating ball driving mechanism includes the connecting rod for driving spool, the floating ball that is connected with connecting rod, and connecting rod is two connecting rods, and two It is provided with water-level regulator between connecting rod, water-level regulator includes angle demodulator, the angle adjustment device being connected with angle demodulator, Angle demodulator includes that surface surrounding is evenly arranged with the round stationary plane of radioactivity tooth, is arranged on the round stationary plane center of circle Annulus is fixed on the nut on round stationary plane by screw rod, the annulus being socketed on screw rod, the opposite round stationary plane of annulus Medial surface is provided with surrounding and is evenly arranged with radioactivity tooth, and angle adjustment device includes fork, swings the fork for being connected to fork Swing rod in mouthful is respectively arranged in swing rod in the corresponding fork of prong inner body upper flat with screw hole above and below Platform, the lower platform with screw hole, the upper adjusting screw for being thread through screw hole are fixed on upper mounting plate by top nut, upper adjusting spiral shell The lower end of silk is pressed on swing rod, and the lower adjusting screw for being thread through screw hole is fixed on lower platform by lower nut, lower adjusting spiral shell The upper end of silk is pressed on swing rod, wherein a connecting rod is fixedly connected with the round stationary plane or annulus of angle demodulator, accordingly The annulus of angle demodulator or round stationary plane are fixedly connected with the fork of angle adjustment device or swing rod, corresponding angle The swing rod or fork of micro actuator are fixedly connected with another connecting rod.

When work, by the adjusting of angle demodulator, the angle between two connecting rods can be adjusted to stepless wide-angle, by adjusting The position of upper adjusting screw, lower adjusting screw, can angle between two connecting rod of stepless changing, after the completion of angular adjustment, two The posture of connecting rod is fixed and invariable, and therefore, the gravitation energy of floating ball effectively passes through two connecting rods band movable valve plug and acts.

Compared with the prior art, having can use in the water tank of narrow space the utility model, meanwhile, and can prevent When carrying is jolted, wide-angle that is that the position of ball-cock assembly will not shift and can be carried out more than 90 degree is adjusted, meanwhile, and it is able to achieve nothing The advantages of grade is accurately adjusted, and can efficiently use floating ball gravity drive.
