The water supply pipe network and the secondary water supply apparatus are connected with the water storage tank. The exhaust pipe is arranged at the top of the water storage tank and the composite ball vacuum release valve is arranged at the lower part of the exhaust pipe. The tap water pipe network water-intaking protection device of the utility model overcomes the defects in the prior art, which has high reliability, no mechanical failure, simple manufacture and convenient maintenance.
Description
Technical field
The utility model relates to a kind of tap water secondary water supply equipment when public supply mains are fetched water, and to the device of water supply network implementation pressure stability and protection, belongs to the plumbing technical field.
Background technology
Along with the expansion day by day of city size, building constantly increases, and each biotope and highrise building all are provided with the conveying of tap water secondary, pressurized equipment, thereby the city tap-water water supply network is produced suction and the threat of formation negative pressure.For ensureing the safety of city tap-water water supply network, the special present technique that proposes.
Summary of the invention
The purpose of this utility model is a kind of pipe network water intaking of design protective device; it is connected that public supply mains and tap water secondary are carried, between the pressurized equipment; original operating pressure and the secondary that makes full use of pipe network carried, the pressure of pressurized equipment; guarantee the normal water of user, and guarantee the pressure stability and the safety of water supply network.
The utility model is to take following technical scheme to realize:
Pipe network water intaking protective device comprises water supply network, water tank, secondary water-supply equipment and stack, it is characterized in that it comprises that also the drainage of composite ball vacuum cuts down; Described water supply network and secondary water-supply equipment are connected on the water tank tank body, and stack is positioned at the water tank top, and the drainage of composite ball vacuum is cut down and is positioned at below the stack.
Aforesaid pipe network water intaking protective device, it is characterized in that the drainage of wherein said composite ball vacuum is cut down comprises and cuts down body, ball sealer, connecting rod, ball float, shell, end railing and clamp nut that wherein said ball sealer and ball float are positioned at the drainage of composite ball vacuum and cut down body cavity; Ball sealer is connected by connecting rod with ball float; End railing is in below the ball float; The drainage of whole composite ball vacuum is cut down by clamp nut and is connected on the water tank tank body, and tracheae above runs in.
The utility model provides a kind of city tap-water pipe network water intaking protective device, utilizes a metallic seal water tank water and a jar interior composite ball vacuum drainage to cut down, and realizes under the balanced action of water level buoyancy and jar internal pressure and ductwork pressure.The utility model tap water pipe network water intaking protective device has overcome the deficiency of conventional art, and the reliability height does not have mechanical fault and takes place, and makes simple, easy to maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model pipe network water intaking protective device;
Fig. 2 is the structural representation that the composite ball vacuum drainage of the utility model pipe network water intaking protective device is cut down.
The specific embodiment
As Fig. 1-water intaking of the utility model pipe network protective device, wherein valve body (1), ball sealer (2), connecting rod (3), ball float (4), shell (5), end railing (6), pad (7), clamp nut (8), stack (9), nut (10), water supply network (11), water tank (12), secondary water-supply equipment (13) and composite ball vacuum release valve (14) shown in Figure 2.Arm water intaking from city tap-water water supply network (11) is connected on the water tank of the present utility model (12) water filling in jar.When water level still during the position of no show composite ball vacuum release valve (14), the interior gas of water tank (12) is got rid of by the composite ball vacuum release valve of opening (14).When water level arrives the position of composite ball vacuum release valve (14), ball float in the composite ball vacuum release valve (14) is under the water level buoyancy function, ball sealer (2) in the composite ball vacuum release valve (14) is held up, close composite ball vacuum release valve (14), stop exhaust.Water level in the water tank (12) continues to rise, and makes a jar inner top gas compression, when hydraulic pressure is consistent with ductwork pressure in jar, stops water filling voluntarily.(user can continue water under this pressure state) is when secondary is carried, pressurized equipment work and flow be during greater than the water supply network flow; drawdown then jar; drawdown is to composite ball vacuum release valve (14) when the position is following; ball float (4) in the composite ball vacuum release valve (14) also descends and opens composite ball vacuum release valve (14); air is entered in the jar; avoid jar interior vacuum (negative pressure) that forms, thus the safe operation of protection water supply network.
The structure of composite ball vacuum release valve (14) and operating principle explanation: composite ball vacuum release valve (14) is installed on the top of water tank (12), composite ball vacuum release valve (14) by: valve body (1), ball sealer (2), connecting rod (3), ball float (4), shell (5), end railing (6), pad (7), clamp nut (8), nut parts such as (10) assemble.(Fig. 2) operating principle of composite ball vacuum release valve D is: when water level rises picking-up ball float (4), under the guide effect of valve body (1) and shell (5), ball sealer (2) is closed leakage port, make jar interior gas compression and build-up pressure, when drawdown, ball float (4) falls to driving ball sealer (2) and falls, and air is entered in the jar, avoids jar interior vacuum that forms.The volume ratio of ball float (4) and ball sealer (2) makes it to guarantee under buoyancy function, and the guide effect of valve interior wall and shell makes closing, opening reliably of composite ball vacuum release valve (`14).
The foregoing description limits the utility model never in any form, all take to be equal to replace or technical scheme that equivalent transformation obtained, all drop within the protection domain of the present utility model.
