Abstract
The utility model relates to a valve, in particular to a double-board ball valve with a water adding tank, which comprises a ball valve body with a double-ball-face-board structure and a water adding tank connected onto the upper portion of the ball valve body. The water adding tank is connected with a water inlet of the ball valve body through a pipeline, and a drainage auxiliary valve is arranged on the pipeline. A check valve is installed on a pipeline connected between an external water inlet and the water inlet of the ball valve body. A water level detection device is arranged inside the water adding tank. When the sealing pressure water is cut off suddenly, the water adding tank can automatically supply water to the valve and cut off media reliably and thoroughly.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of double-plate ball valve that is provided with water supply tank.
Background technique
The double-plate ball valve is installed in the function that can play multi-purpose valve on the gas pipe line, use the double-plate ball valve can substitute the effect of a seal butterfly valve and a blank-plate valve, it opens and closes rapidly, has overcome the shortcoming that two deck valve doors must be coordinated to operate respectively, but has the unsafe factor of internal leakage.
The model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of thorough cut-out medium, be provided with the double-plate ball valve of water supply tank safely and efficiently.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of double-plate ball valve that is provided with water supply tank, comprise ball valve body with two spherical plate structures and the water supply tank that is connected ball valve body top, described water supply tank is connected with the water intake of ball valve body by the pipeline that the draining auxiliary valve is installed, on the official road that is connected between the water intake of outside water intake and ball valve body safety check is installed, is provided with condensate tank of dehumidifier in the water supply tank.
Condensate tank of dehumidifier in the described water supply tank is made up of float and the warning device that is used to measure the vertical line of water level and be installed in the float.
Described warning device is connected to the external control chamber.
The beneficial effects of the utility model are: the water supply tank that the utility model is provided with can be given the valve moisturizing automatically after sealing load water accidental interruption, thoroughly cut off medium very reliably.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. ball valve body, 2. water supply tank, 3. draining auxiliary valve, 4. water intake, 5. outside water intake, 6. safety check, 7. float, 8. vertical line.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of double-plate ball valve that is provided with water supply tank, comprise ball valve body 1 with two spherical plate structures and the water supply tank 2 that is connected ball valve body 1 top, described water supply tank 2 is connected with the water intake 4 of ball valve body 1 by the pipeline that draining auxiliary valve 3 is installed, on the official road that is connected between the water intake 4 of outside water intake 5 and ball valve body 1 safety check 6 is installed, is provided with condensate tank of dehumidifier in the water supply tank 2.
Condensate tank of dehumidifier in the water supply tank 2 is made up of float 7 and the warning device that is used to measure the vertical line 8 of water level and be installed in 7 li of floats, and warning device is connected to the external control chamber.
When normal water supply, water supply tank 2 is intake automatically, and water stops into water after completely automatically, and is standby.After the pipeline accident is cut off the water, because water intake 4 has safety check 6, water in the ball valve body can not reflux, at this moment water supply tank 2 supplies water from trend water intake 4, when the drawdown of water supply tank 2 sealed the water liquid level and drops to certain distance in certain liquid or ball valve body 1, the emergency alarm that float is 7 li was connected the external control chamber and is reported to the police.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
