Abstract

The utility model discloses a vacuum suppressor used in water supply system, which enables the water supply system to prevent the generation of negative pressure in the service pipe net when the water supply system is in direct connection with service pipe net, and to maintain the pressure balance of service pipe net. The utility model includes a suppressor tube, a cover board with a through-hole on the center provided on the upper end of the tube body and coordinated with the tube body with air tightness, a floating ball with a guide rod arranged inside the tube body cavity, a clamp board arranged on the floating ball guide rod positioned at the inner part of the cover board, and a sealing washer arranged between the clamp board and the cover board. The floating ball is flexibly connected with a guide rod bracket on the upper end of the tube body by the guide rod.

Description

A kind of vacuum suppresser that is used for water supply installation
Technical field
The utility model relates to a kind of water supply installation, relates in particular to a kind of vacuum suppresser that is used for water supply installation.
Background technology
In the city tap-water pipe network, if water supply installation directly connects with the tap water pipe network,, destroy the pressure balance of tap water pipe network because water pump suction produces negative pressure easily in pipe network, impact for certain customers' water.For this phenomenon, the solution that existing water supply installation is all desirable without comparison.
Utility model content the purpose of this utility model is the problem that exists at prior art, and a kind of vacuum suppresser that is used for water supply installation is provided.It can make water supply installation suppress to produce negative pressure in the pipe network when directly connecting with the tap water pipe network, keeps the pressure balance of tap water pipe network.
The technical solution of the utility model comprises cylindrical shell, be provided with in the upper end of cylindrical shell one have through hole and cooperate with described cylindrical shell tightness cover plate, described cylinder lumen is provided with the ball float of a band guide rod, the ball float guide rod that is positioned at described cover plate inside line is provided with a clamp, be provided with a seal between this clamp and the described cover plate, ball float is connected on the guide bar support of cylindrical shell upper end by its guide rod.
Described seal be one with described clamp upper surface be bonded as one rubber seal.
The position that described cover plate soffit contacts with described seal is provided with several reverse V-shaped grooves.
Described guide bar support top is provided with shield plate.
The utility model is because can be in time according to the SEA LEVEL VARIATION in the flow straightener in the water supply installation (cistern), automatically the exhaust and the air inlet of control flow straightener, produce negative pressure in the pipe network when avoiding water supply installation directly to connect with the tap water pipe network, thereby for the user provides tap water stable, clean, health, and it is simple in structure, easy to implement, low cost of manufacture.
Description of drawings
Fig. 1 is the utility model theory structure schematic diagram.
The specific embodiment
As shown in Figure 1, cover plate 5 is fixedly connected on the upper end of cylindrical shell 2 through the bolt tightness; Guide bar support 4 is fixed on the cover plate 5; Ball float 3 places cylindrical shell 2 inner chambers and is movably connected on guide bar support 4 by the guide rod 1 that the center through hole on cover plate 58 upwards grows guide bar support 4.Clamp 6 places downside cylindrical shell 2 inner chambers of cover plate 5, and tightness is fixed on the guide rod 1.Rubber seal 7 is adhered to clamp 6 upper surfaces, and clamp 6 can contact through the position tightness that rubber seal 7 and cover plate 5 are provided with reverse V-shaped groove 11 and form sealing with cover plate.
The guide rod 1 that is positioned at guide bar support 4 upsides is provided with limited block (stop nut) 9.The set reverse V-shaped groove 11 of the soffit of cover plate 5 can improve sealing performance, improves sealing effectiveness.Guide bar support 4 tops are provided with shield plate 12.
Cylindrical shell 2 lower ends are fixedly connected on the flow straightener (cistern) 10 of water supply installation and form UNICOM with flow straightener 10 through the bolt tightness.Flow straightener 10 is respectively equipped with water inlet and delivery port.When inflow in the flow straightener 10 less than water yield or flow straightener during because of drawdown, ball float 3 drives clamp 6 toward falling by guide rod 1, this moment, flow straightener 10 inner chambers communicated with atmosphere by center through hole 8.Spacing adjusting can be carried out by stop nut 9 positions of regulating guide rod 1 upper end in the position of clamp 6 minimum whereabouts.
When the liquid level in the flow straightener 10 rose, ball float was subjected to liquid buoyancy and drives clamp 6 risings, and gas is discharged along center through hole 8 in former thereupon flow straightener 10 inner chambers.When clamp 6 rose to cover plate 5 positions, clamp 6 was by rubber seal 7 and cover plate 5 contact seals, and this moment, clamp 6 rose to upper limit position; After this kept as liquid levels in the flow straightener 10 or when continuing to rise, flow straightener 10 will keep sealing always, thereby can not produce leak of liquid.
When flow straightener 10 middle water levels descend, ball float 3 descends when making clamp 6 fall to breaking away from cover plates 5, and cylindrical shell 2 inner chambers or flow straightener 10 inner chambers and atmosphere equipressure can be avoided generation vacuum in the water system and form negative pressure, like this, can keep the pressure balance of tap water pipe network.But the set shield plate 12 dust protection fouls in guide bar support top fall in the flow straightener.
The utility model utilizes the upper and lower motion of ball float flow straightener to be inflated or exhaust and sealing function, thereby has reached the purpose that suppresses vacuum.Because air inlet, exhaust space are big, to moisture storage capacity in the large-scale water system, carry the water yield big, the flow straightener that water-level fluctuation is big, as volume at 10-35m 3Flow straightener, it is better that it suppresses vacuum effectiveness, solved the problem that is difficult to suppress negative pressure in the large-scale water system.
