Abstract
The utility model provides a mining ball valve which mainly solves the problem that an existing mining ball valve is not long in service life. The mining ball valve comprises a valve body, a base, a valve cover, a valve clack and an operation mechanism. The valve body is hollow, the valve clack is located in the valve body, the operation mechanism is located on the valve cover and is connected with the valve clack, and the valve clack is of a spherical shape. The mining ball valve is characterized in that a sealing gasket is arranged between the valve body and the valve clack, the surface of the sealing gasket is of an arc shape, annular grooves are formed in the upper side and the lower side of the valve clack, the interior of each annular groove is wide, an opening of each annular groove is narrow, and an O-shaped seal ring is arranged in each annular groove and is in tight fit with the surface of the sealing gasket. The mining ball valve plays a sealing role in fit between the seal rings and the sealing gasket, and enables sealing mode of direct fit between the sealing gasket and the surface of the valve clack to be replaced, and service life is greatly prolonged.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of mining ball valve.
Background technique
In mining system, ball valve is a kind of valve that often is used, but the working life of ball valve is very short, often damages, and what mainly damage is the interior sealing configuration of ball valve, causes sealing variation.
The model utility content
In order to overcome disadvantages of background technology, the utility model provides a kind of mining ball valve, has mainly solved existing mining ball valve not long problem in working life.
The technological scheme that the utility model adopts is: a kind of mining ball valve, comprise valve body, base, valve gap, flap and operating device, described valve body is hollow, and flap is positioned at valve body, operating device is positioned on the valve gap and with flap and is connected, described flap is spherical, is provided with sealing gasket between described valve body and the flap, and described sealing gasket surface is arc; The upper and lower both sides of described flap are provided with circular groove, and circular groove inside is wide, and opening is narrow, are provided with the O RunddichtringO in the circular groove, tightly fit in described O RunddichtringO and sealing gasket surface.
Described circular groove cross section is swallow-tail form.
Described O RunddichtringO and sealing gasket all are rubber.
Described valve body is two-part, all is connected and fixed with valve gap and base.
Described valve body is connected with valve gap and base by thread.
The beneficial effects of the utility model are: this ball valve is that seal action is played in the applying between seal ring and the sealing gasket, has replaced sealing gasket directly and the sealing of flap surface applying, has increased working life greatly.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As Fig. 1 in conjunction with shown in Figure 2, a kind of mining ball valve, comprise valve body 1, base 2, valve gap 3, flap 4 and operating device 5, described valve body 1 is hollow, and flap 4 is positioned at valve body 1, and operating device 5 is positioned on the valve gap 3 and with flap 4 and is connected, and described flap 4 is spherical, be provided with sealing gasket 6 between described valve body 1 and the flap 4, described sealing gasket 6 surfaces are arc; Described flap 4 upper and lower both sides are provided with circular groove 7, and circular groove 7 is inner wide, and opening is narrow, is provided with O RunddichtringO 8 in the circular groove 7, and described O RunddichtringO 8 is tightly fitted with sealing gasket 6 surfaces.Described circular groove 7 cross sections are swallow-tail form.Described O RunddichtringO 8 all is rubber with sealing gasket 6.When flap 4 rotated, O RunddichtringO 8 contacted with sealing gasket 6, after rubbing for a long time, even the surface wears away, but because O RunddichtringO 8 all is rubber with sealing gasket 6, thus can carry out automatic compensation sealing, so the working life of having improved this ball valve greatly.
Described valve body 1 is two-part, all is connected and fixed with valve gap 3 and base 2.Described valve body 1 and valve gap 3 and base 2 like this can be convenient in assembling by being threaded.
Every technician's notice: though the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this model utility; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
