Description
Technical field
The utility model water meter technical field, is specifically related to a kind of water meter with ball valve.
Background technology
At present, the water meter that water supply company provides to resident family is a valve of a water meter configuration mostly, and will be connected by connecting tube between valve and water meter, the in the situation that of valve-off, the connecting tube of taking apart between water meter and valve can reach the object of water steathily easily, and this brings a lot of inconvenience to the daily management of Running-water Company; And traditional water meter valve, the poor sealing of its valve rod lower end and valve interior wall, in the situation that hydrodynamic pressure is excessive, the fluid easily gap between valve rod and valve interior wall upwards flows out, the control gear or the topworks that flow into valve rod top, bring inconvenience or lose; Although there is at present a kind of band valve formula water meter, its complicated structure, be produced into should, and due to quality problems such as leaking appear in valve, can cause and scrap together with water meter, cause waste.
The deficiencies in the prior art are: traditional Water meter with valve, and dismounting is too convenient, easily causes water phenomenon steathily; The poor sealing of valve rod lower end and valve interior wall, fluid easily flows into topworks or control gear from gap between the two, affects valve working; After valve goes wrong, can scrap together with water meter, cause damage and waste.
Utility model content
The purpose of this utility model is to provide the water meter with ball valve of good seal performance between a kind of valve rod and valve interior wall.
For achieving the above object, the technical solution of the utility model is as follows: a kind of water meter with ball valve, comprise water meter gauge outfit and be arranged on the ball valve in the flowtube of this water meter gauge outfit, described ball valve comprises valve body and is arranged on valve rod and the ball valve core in this valve body, described valve body entrance point and flowtube are tightly connected, valve outlet end is water pipe link, described valve rod is arranged in valve rod mounting hole, this valve rod upper end connects carries out body, valve rod lower end is stretched in valve pocket and is coordinated with ball valve core, on the sidewall of described valve rod lower end, be provided with the seal boss of a circle taper, sealing boss is big top and small bottom, the conical surface and the valve interior wall of described seal boss are close to, and will between described valve rod mounting hole and valve pocket, seal.
Adopt said structure, ball valve is directly tightly connected with flowtube, reduces intermediate connection tube part, has ensured to be not easy on the other hand pull down ball valve by sealing effectiveness on the one hand, can reduce and steal water phenomenon; The seal boss of valve rod and valve interior wall surface of contact are tapered slope, and while being subject to hydrodynamic pressure in valve rod lower end, between valve rod and valve interior wall, more pressure is tighter, makes sealing effectiveness better, has prevented that fluid from flowing out from valve rod mounting hole.
Described valve rod mounting hole lower end is up-small and down-big shoulder hole, described seal boss is positioned at the bigger diameter end of this shoulder hole, between seal boss and the step surface of shoulder hole, conical seal ring is installed, the conical surface of sealing boss is pressed on conical seal ring on step.
Valve rod mounting hole lower end forms up-small and down-big shoulder hole, and conical seal ring is arranged on this step surface, and while being subject to hydrodynamic pressure in valve rod lower end, the conical surface of seal boss is pressed on conical seal ring on step, further strengthens its sealing effectiveness.
On the outer wall of described valve body entrance point, with the corresponding ring flange that is provided with on the outer wall of flowtube, valve body entrance point is against on the end face of flowtube, and by being located in the bolt-locking on ring flange.
Between valve body entrance point and the end face of flowtube, O-ring seal can be set, enhanced leaktightness effect.
In described valve body entrance point, be provided with the ball valve end seat of ring-type, threaded engagement between this ball valve end seat outer wall and valve body entrance point inwall, is provided with valve seat on ball valve end seat, between this valve seat and ball valve end seat, is provided with the first O-ring seal.
This structure is convenient to the installation and removal of spool, valve seat etc., and ball valve end seat will compress between valve seat and spool, ensures its sealing.
On the valve rod outer wall of described seal boss top, offer two circle mounting grooves, in this two circles mounting groove, the second O-ring seal is installed.
Between described valve body upper end and water meter gauge outfit, be provided with the 3rd O-ring seal.
Said structure makes two-stage sealing, further enhanced leaktightness effect between valve rod and valve rod mounting hole.
The beneficial effects of the utility model are: the utility model is simple in structure, are connected closely between ball valve and water meter gauge outfit, can reduce water phenomenon steathily; Occur after leakage problem at ball valve simultaneously, can change separately the parts of ball valve, and can not make that water meter is whole to be scrapped, reduce the loss; Strengthen the sealing effectiveness between valve rod and valve rod mounting hole inwall, effectively prevented that fluid from flowing out between valve rod and valve rod mounting hole inwall, ensured that topworks and control gear are interference-free.
