Abstract
The utility model discloses a compound high speed exhaust valve which includes a valve body; the lower end of the valve body is provided with a liquid inlet; the upper end of the valve body is provided with a main exhaust port; a dustproof net is arranged outside the main exhaust port; a dust-proof hood is arranged outside the dust-proof net; a vertical guide pole is arranged in the valve body; a floating body is sleeved on the guide pole in a sliding way; the floating body rises along the guide pole and can plug the main exhaust port; the upper end of the valve body is provided with a tiny exhaust valve; the tiny exhaust valve includes a cylinder communicated with the inside of the valve body; the top end of the cylinder is provided with a tiny exhaust port; the inside of the cylinder is provided with a floater capable of plugging the lower end of the tiny exhaust port. The compound high speed exhaust valve is arranged on a water supply pipeline which can exhaust the gas in the pipeline during running; when a negative pressure is generated in the pipeline, a plurality of air is quickly sucked into the pipeline to balance the pipeline pressures.
Description
Background technique
The utility model relates to the valve class, specifically is a kind of combined high-speed outlet valve.
Background technique
At present, outlet valve has a lot of structural types, in use have leak, gas is stifled, also have suction tolerance not reach the phenomenon of requirement, minimum gas row such as does not go out at a lot of defectives in the pipeline.Need a kind of outlet valve to address the above problem, to ensure the property safe and reliable to operation of water supply line facility.
The model utility content
The purpose of this utility model provides a kind of combined high-speed outlet valve, is installed on the water supply line, can drain the operating gas of pipeline, when pipeline produces negative pressure, and a large amount of quick intake lines of air, equalizing main pressure.
The technical solution of the utility model is as follows:
A kind of combined high-speed outlet valve, include valve body, the lower end of valve body is provided with liquid entering hole, the valve body upper end is provided with main vent, the main vent outer cover is equipped with Air Filter, and Air Filter has dust-proof cover outward, is provided with vertical guide rod in the valve body, flip sleeve is equipped with buoyancy aid on the guide rod, and buoyancy aid rises to block up along guide rod and places described main vent; The upper end of valve body is provided with little outlet valve, and little outlet valve includes the cylindrical shell with described valve inner UNICOM, and there is little row mouthful on the top of cylindrical shell, and inner barrel is provided with can block up the float that places little Pai Kou lower end.
Described little outlet valve is positioned at described dust-proof cover inboard.
Main vent of the present utility model be provided with outward Air Filter prevent foreign material waft into, micro-outlet valve is located at protective housing inside, be difficult for to stop up and damages.Special nonmetal float when in the valve body during no gas, is sealed little row mouthful; When in the valve body gas being arranged, gas rises to the top, and float buoyancy reduces to descend, little row mouthful exhaust; When pipeline produced negative pressure, inside and outside differential pressure disappeared outlet valve selfsealings state, and all relief openings are all opened, a large amount of quick intake lines of air, the pressure in the equalizing main.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
