Description
Technical Field
The utility model relates to the field of water supply equipment, in particular to a vacuum compensator for water supply equipment.
Background
The vacuum compensator is a device which is frequently used in non-negative pressure water supply equipment and can eliminate negative pressure of the water supply equipment when water supply network is cut off or the pressure is low. The traditional vacuum compensator mostly adopts the matching of a single floating ball and an air inlet channel structure to realize the communication and the sealing between the interior of the water supply equipment and the outside, so that the water supply equipment compensates the air pressure. Although the structure solves the problem of negative pressure generated by the water supply equipment, the following defects still exist: firstly, when the floating ball bears a large water pressure, the floating ball is easy to deform and the problem of water overflow is caused; secondly, when the water supply equipment compensates the air pressure through the vacuum compensator, external impurities easily enter a polluted water source along with the air pressure.
SUMMERY OF THE UTILITY MODEL
The utility model provides a vacuum compensator for water supply equipment, which can realize the sealing performance inside and outside the water supply equipment through the vacuum compensator and prevent water in the water supply equipment from overflowing when the water pressure in the water supply equipment is higher.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
a vacuum compensator for water supply equipment comprises a shell, wherein the bottom of the shell is connected with a supporting sleeve in a penetrating manner, sealing gaskets are arranged between the supporting sleeve and the shell as well as between the supporting sleeve and the water supply equipment, a ball float rod movably penetrates through the supporting sleeve, a limiting part is formed at the upper end of the ball float rod, a ball float assembly is connected at the lower end of the ball float rod, a sealing sleeve is integrally connected to the bottom of the supporting sleeve at the periphery of the ball float assembly, a first air channel is formed between the ball float assembly and the sealing sleeve, a second air channel communicated with the first air channel is arranged on the supporting sleeve on one side of the ball float rod, and an air hole communicated with the second air channel is arranged on the shell;

When the vacuum compensator is used, the vacuum compensator is arranged on water supply equipment, and is particularly arranged on a steady flow tank of the water supply equipment. When the municipal network pipe supplies water to the water supply equipment, if the water pressure is low, outside air enters the flow stabilizing tank through the air hole of the vacuum compensator, the second air channel and the first air channel to balance the pressure; if water pressure is great, the water level in the stationary flow jar rises, discharges through first air passage, second air passage, gas pocket thereupon in proper order, later along with the continuation of water level rises, and the ball float subassembly rises and seals the cover cooperation and realizes the shutoff, avoids the water in the stationary flow jar to spill over, and is concrete, and the ball float of ball float subassembly rises and first annular seal portion cooperation shutoff, and the ball float cooperates the shutoff with second annular seal portion simultaneously, realizes two shutoff customs blocks, and sealed effect is better. Even the water pressure in the stationary flow tank is great, make lower floater bear great pressure deformation for lead to producing the gap between floater and the second annular sealing portion down, nevertheless the floater bearing pressure of floating on it is less, still can realize going up the shutoff between floater and the first annular sealing portion, thereby the better water overflow in the prevention stationary flow tank.
In one example, an inner diameter of the second annular sealing portion is greater than an inner diameter of the upper float ball. So design, better installation can be behind the ball-cock stem installation ball-cock assembly, and the ball-cock stem runs through fixed spacing portion behind the support cover from seal cover lower extreme rebound.
In one example, the second air passage is uniformly provided with a plurality of second air passages along the circumferential direction of the floating ball rod, and the air pressure borne by the floating ball assembly is uniform.

The design of above-mentioned structure can filter the outside air to a certain extent, guarantees that the water source in the water supply equipment does not receive the pollution, and filters the circle and use after a period, can be more convenient change it.
In one example, the air hole is formed in the side wall of the base shell from outside to inside in an inclined and upward mode, and impurities in the atmosphere are not prone to entering the shell in the air inlet process.
In one example, the bottom of the filter ring is turned outwards to form a dust collecting groove, during air inlet, air entering the base shell through the air holes impacts the filter ring, and settled dust is collected in the dust collecting groove to facilitate cleaning.
In one example, the outer circumference of the housing is formed with a fixed disk on which a fixed hole is provided.
By adopting the technical scheme, the utility model has the advantages that:
1. the vacuum compensator is applied to water supply equipment, can realize gas communication between the water supply equipment and the outside so as to balance water pressure, and when the water pressure is higher, the water level rises, an upper floating ball and a lower floating ball of the vacuum compensator are respectively sealed with a first annular sealing part and a second annular sealing part, and meanwhile, two sealing checkpoints are completed, so that the sealing effect is better; even if the lower floating ball is deformed due to high water pressure and a gap is formed between the lower floating ball and the second annular sealing part, the pressure of water rising through the gap on the upper floating ball is low, and the sealing between the upper floating ball and the first annular sealing part is not influenced, so that the water is prevented from overflowing.
2. The matching design of the filtering ring and the shell can filter the gas entering the water supply equipment from the outside, so as to avoid the water source pollution caused by the balance water pressure; the filter ring after being used for a period of time is convenient to replace.
