Abstract

The utility model relates to a floating ball valve, which comprises a valve body, a valve seat, a valve rod and a ball body, wherein the ball body is arranged in the valve body; a gap is formed between the ball body and the valve body; one end of the valve rod is fixedly connected with the ball body after penetrating the valve body, and a handle is arranged at the other end of the valve rod; and packing and a packing gland are arranged between the valve rod and the valve body. The floating ball valve provided by the utility model is characterized in that a pollution discharge port, for conducting the gap and the external of the valve body, is arranged at the bottom of the valve body; and a pollution discharge valve is arranged at the pollution discharge port. The technical scheme provided by the utility model has better sealing property between the ball body and the valve seat.

Description

Floating ball valve
Technical field
The utility model relates to a kind of floating ball valve.
Background technique
The spheroid of floating ball valve floats, and under the pressure medium effect, spheroid can produce certain displacement and be pressed on the sealing surface of outlet end, guarantees the outlet end sealing.Floating ball ball valve simple in structure; Good airproof performance has all been passed to the exit seal circle but spheroid bears the load of working medium, therefore will consider that can sealing ring material hold out against the work loads of spheroid medium; When receiving the elevated pressures impact, spheroid may squint.Traditional floating ball valve generally includes valve body, valve seat, valve rod and spheroid, and spheroid is arranged in the valve body; Leave the gap between spheroid and the valve body, valve rod one end passes valve body and is fixedly connected with spheroid, and the valve rod the other end is provided with handle; Be provided with filler and Gland between valve rod and the valve body; Its pipeline internal medium is easily residual to gap between spheroid and the valve body, and causes between spheroid and the valve seat sealability undesirable, and; When the gap internal air pressure is too high between spheroid and the valve body, can influence the sealability between spheroid and the valve seat equally.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide the better floating ball valve of sealability between a kind of spheroid and the valve seat.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of floating ball valve, comprise valve body, valve seat, valve rod and spheroid, and spheroid is arranged in the valve body; Leave the gap between spheroid and the valve body; Valve rod one end passes valve body and is fixedly connected with spheroid, and the valve rod the other end is provided with handle, is provided with filler and Gland between valve rod and the valve body; It is characterized in that: said valve body bottom position is provided with said gap of conducting and the outside sewage draining exit of valve body, and said sewage draining exit place is provided with blowdown valve.
Through adopting technique scheme, residual pipeline internal medium to gap between spheroid and the valve body can be got rid of by the sewage draining exit and the blowdown valve of valve body bottom position, thereby makes that sealability is better between spheroid and the valve seat.
The utility model further is set to: said valve body upper position is provided with said gap of conducting and the outside relief opening of valve body, and said exhaust ports is provided with outlet valve.
Through adopting technique scheme, can carry out exhaust by outlet valve when the air pressure between spheroid and the valve body in the gap is too high, further improve the sealability between spheroid and the valve seat.
The utility model further is set to: said valve rod and spheroid fixed connection place are provided with the cylindricality blind hole, are provided with pressure spring in the said cylindricality blind hole.
Through adopting technique scheme, when valve rod rotated, the pressure spring two ends can both contact with valve rod and spheroid respectively all the time, to derive the static on the spheroid.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model floating ball valve example structure figure.
Embodiment
Referring to accompanying drawing 1, the disclosed floating ball valve of the utility model comprises valve body 1, valve seat 2, valve rod 3 and spheroid 4; Spheroid 4 is arranged in the valve body 1, leaves the gap between spheroid 4 and the valve body 1, and valve rod 3 one ends pass valve body 1 and are fixedly connected with spheroid 4; Valve rod 3 the other ends are provided with handle 5; Be provided with filler 6 and Gland 7 between valve rod 3 and the valve body 1, said valve body 1 bottom position is provided with the sewage draining exit of said gap of conducting and valve body 1 outside, and said sewage draining exit place is provided with blowdown valve 8.Through adopting technique scheme, residual pipeline internal medium to gap between spheroid 4 and the valve body 1 can be got rid of by the sewage draining exit and the blowdown valve 8 of valve body 1 bottom position, thereby makes that sealability is better between spheroid 4 and the valve seat 2.
Present embodiment further is provided with: said valve body 1 upper position is provided with the relief opening of said gap of conducting and valve body 1 outside, and said exhaust ports is provided with outlet valve 9.Through adopting technique scheme, can carry out exhaust by outlet valve 9 when the air pressure between spheroid 4 and the valve body 1 in the gap is too high, further improve the sealability between spheroid 4 and the valve seat 2.
Present embodiment further is provided with: said valve rod 3 is provided with the cylindricality blind hole with spheroid 4 fixed connection places, is provided with pressure spring 10 in the said cylindricality blind hole.Through adopting technique scheme, when valve rod 3 rotated, pressure spring 10 two ends can both contact with valve rod 3 and spheroid 4 respectively all the time, to derive the static on the spheroid 4.Need to prove that here the cylindricality blind hole can be arranged on valve rod 3 or the spheroid 4, convenient in order to process, present embodiment is preferred, and the cylindricality blind hole is arranged on the valve rod 3.
