Abstract
The utility model discloses a positive pressure self-priming water feeding device for over head steam injection pump, comprising a water tank with a water inlet and a water outlet, wherein, an exhaust opening is arranged at the top of the water tank; a floating ball is positioned in the water tank and the size of the floating ball is matched with the caliber of the exhaust opening; a valve structure is positioned in the water outlet. The utility model is positioned on an over head platform or the position of zero to five meters lower than the platform; the water inlet of the water tank is connected with a pool and the water outlet is connected with a condenser; the water in the pool flows into the water tank and then flows into the condenser through the water outlet when the water is supplied normally; when the system has power failure or is broken, the water pump stops working and the pool stops supplying the water tank with water, but the water tank still has the remaining water, the exhaust opening is forced to open under the atmospheric pressure and a water seal is formed between the remaining water in the tank and the condenser, thereby avoiding the phenomenon of pumping; when the water line in the water tank decreases gradually, a valve at the water outlet for throttling the water seal closes gradually and the water outlet is closed completely until no water is left in the water tank, which can prevent the air from being pumped into the condenser and protect the vacuum degree in the condenser from being destroyed.
Description
Technical field
The utility model relates to a kind of high chord position steam injection equipment, especially a kind of high chord position vapor pump malleation self-priming water-supply apparatus.
Background technique
The condensed water of condenser directly enters in the pond through waste pipe in the existing high chord position vapor pump, and then by water pump squeeze into carry out in the condenser recycling, when system breaks down or have a power failure, water pump quits work, the phenomenon that air is drawn into condenser will take place, degree of vacuum in the condenser is damaged, thereby influences the proper functioning of whole system.
The model utility content
The purpose of this utility model provides a kind of, when system takes place to have a power failure, can guarantee the impregnable high chord position vapor pump malleation self-priming water-supply apparatus of degree of vacuum in the condenser.
The technical solution of the utility model is: a kind of high chord position vapor pump malleation self-priming water-supply apparatus, comprise water tank and water intake and water outlet on it, have a relief opening in tank top, in water tank, be provided with a ball float, the size of this ball float and the bore of relief opening are suitable, and a valve mechanism is housed on water outlet.
Above-mentioned valve mechanism is made up of ball float and a dish valve of a band connecting rod, and the dish valve is made up of the rotating open-close type valve plate of valve seat and Qi Nei, and valve plate is contained in the rotating shaft, and the connecting rod on this rotating shaft and the ball float links.
The utility model is installed on the overhead bit platform or is lower than the position of platform 0-5 rice, the water intake and the pond of water tank link, water outlet and condenser link, when normally going up water, water in the pond enters in the water tank, water outlet by water tank enters in the condensation again, after power failure or fault take place in system, water pump quits work, and the pond stops to the water tank moisturizing, owing to also have water in the water tank, under atmospheric effect with the Exhaust Open at top, utilize between water in the water tank and the condenser and form water seal, thus can not produce the phenomenon of bleeding, when the water level in the water tank descends gradually, the valve of throttling water seal is slowly closed on the water outlet, when water tank is anhydrous, water outlet is closed fully, prevent that air from by in the condenser of falling the suction, so just can keep the degree of vacuum in the condenser not to be destroyed.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the valve mechanism schematic representation.
Embodiment
The structure of model utility is as shown in Figure 1: comprise water tank 1 and water intake 2 and water outlet 3 on it, have a relief opening 4 in tank top, in water tank, be provided with a ball float 5, the bore of the size of this ball float 5 and relief opening 4 is suitable, the effect of ball float 5 is that the water in water tank 1 will overflow chamber sealing relief opening 4, when reducing, opens water level relief opening 4, to guarantee from sucting the water proper functioning.One valve mechanism 6 is housed on water outlet 3.Water intake 2 links by pipeline 7 and aqua storage tank 8, and water outlet 3 links by pipeline and condenser.Above-mentioned valve mechanism 6 is made up of ball float 9 and a dish valve of a band connecting rod 10 as shown in Figure 2, and the dish valve is made up of the rotating open-close type valve plate 12 of valve seat 11 and Qi Nei, and valve plate 12 is contained in the rotating shaft 13, and the connecting rod 10 on this rotating shaft 13 and the ball float 9 links.The effect of valve mechanism 6 is when the water level in the water tank 1 rises, and valve is opened greatly gradually, and sealing self-priming water outlet 3 when water level is reduced to a certain degree prevents that air from pouring into, destroys vacuum.
Claims (2)
1, a kind of high chord position vapor pump malleation self-priming water-supply apparatus, comprise water tank and water intake and water outlet on it, it is characterized in that: have a relief opening in tank top, in water tank, be provided with a ball float, the size of this ball float and the bore of relief opening are suitable, and a valve mechanism is housed on water outlet.
