The steady-flow tank product category is a lot of on the market, and manufacturer is quite a few, but how to realize the automatic control of liquid level, and each producer is similar.Utilize float valve control, can not guarantee that like this volume of steady-flow tank takes full advantage of; Have and utilize content gauge automatically to control, frequent misoperation can occur.Simultaneously because be to be applied in Drinking Water Industry, can not exert an influence to the health of water quality, because be to be directly connected to city planting ductwork, the pressure-bearing of integral body also there is certain requirement.Therefore, existing steady-flow tank product can't well solve the problem of following four aspects: the one, how to solve the problem of the regulation " not allowing water pump directly to be connected in supervisor draws water " of city planting ductwork on the net; The 2nd, how better to take full advantage of the dischargeable capacity in the steady-flow tank, so that when ductwork pressure fluctuates, reach the maximal regulated water yield; The 3rd, how to guarantee the water level of the pressurized tank between pipe network and the water pump system and prevent that the dried of water pump from turning; The 4th, guarantee that how pressurized tank between pipe network and water pump system when liquid level descends, does not produce negative pressure.
The utility model content
The purpose of this utility model is for deficiency of the prior art, provide a kind of simple in structure, cost is low, can take full advantage of the tank body dischargeable capacity, steady-flow tank that fault is low.
For finishing above-mentioned purpose; the technical solution adopted in the utility model is: steady-flow tank; comprise tank body, water inlet, delivery port, saddle seat; water inlet is connected with city planting ductwork; delivery port is connected with user's pipe network; it is characterized in that: described tank body top is provided with vacuum suppresser and vacuum checking device, and described tank body also is provided with the level detection protective device, and described level detection protective device is connected with switch board.
Further, described level detection protective device is arranged on the side bottom of tank body, comprises that one is arranged on the metal bar in the tank body.
Further, described vacuum checking device adopts distance-transmission pressure gauge.
Further, described tank base also is provided with outlet valve.
Further, described tank base also is provided with sewage draining exit.
Further, described tank body adopts all steel structure.
Compared with prior art, the utlity model has following characteristics: 1, overall cost of ownership is low, does not need complicated electrical equipment and ball float; 2, take full advantage of the volume of steady-flow tank, because traditional floating ball structure more complicated, floating ball structure is long, water in the tank fully is not utilized, and the electrode liquid level is installed in the side of steady-flow tank, highly can try one's best near the bottom, so that the water in the tank can fully be utilized; 3, fault is low, and electrode simple in structure only has a stainless steel bar as electrode, and be not fragile; 4, adopt the corrosion resistant plate of standard pressure vessels thickness, intensity is good, and pressure-bearing is high.5, adopt the structure of all steel, avoided the secondary pollution of water, its structure machinery-free moving part, simple in structure, reliable, easy to maintenance, the life-span is long.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, tank body, 2, water inlet, 3, delivery port, 4, the saddle seat, 5, vacuum suppresser, 6, vacuum checking device, 7, the level detection protective device, 8, switch board, 9, metal bar, 10, outlet valve, 11, sewage draining exit, 12, water pump.
The specific embodiment
Steady-flow tank as shown in Figure 1 comprises tank body 1, water inlet 2, delivery port 3, saddle seat 4, and water inlet 2 is arranged on the top of tank body 1, is connected with city planting ductwork, and delivery port 3 is arranged on the bottom of tank body 1, is connected with user's pipe network.Described tank body 1 top is provided with vacuum suppresser 5 and vacuum checking device 6.Described vacuum suppresser 5 adopts frame for movement, realizes the protection of negative pressure.Described vacuum checking device 6 adopts distance-transmission pressure gauge to measure.
Described tank body 1 also is provided with level detection protective device 7, and described level detection protective device 7 is connected with switch board 8.Described level detection protective device 7 is arranged on the side bottom of tank body 1, adopts the electrode mode to control liquid level, comprises that one is arranged on the metal bar 9 in the tank body, and metal bar 9 is as a utmost point of electric capacity, and the tank container wall is as another utmost point of electric capacity.Two interelectrode media are liquid and top gas thereof.Because the DIELECTRIC CONSTANTS 1 of liquid is different with the DIELECTRIC CONSTANTS 2 on the liquid level, such as: ε 1＞ε 2, then when liquid level raise, total dielectric constant values strengthened thereby the capacitance increase thereupon between two electrodes.Otherwise when liquid level decline, the ε value reduces, and capacitance also reduces.Therefore can measure by two interelectrode electric capacitance change the height of liquid level.During concrete the measurement, the top of electrode bar is across air, and the bottom is full of liquid water.The DIELECTRIC CONSTANTS 0=1 of air, the dielectric constant of measured object are ε r.When the thing position changed, the capacitance variations value Δ C of electrode and the thing position height x of measured material were linear, that is:
In the above-mentioned formula, h is the overall height of steady-flow tank, C
0Be the initial capacitance value.
Described tank body 1 bottom also is provided with outlet valve 10.
Described tank body 1 bottom also is provided with sewage draining exit 11.
Described tank body 1 adopts all steel structure design.The employing automatic argon arc weld connects; Inner surface adopts acid wash passivation to process; External surface adopts mirror finish to process; According to the Specification Design of GB150-2011, design pressure is pressed PN10, and minimum thickness is not less than 4mm.
Operating principle: water pump 12 water inlets in user's pipe network are connected with steady-flow tank, and control system detects its pressure constantly, guarantee not produce negative pressure in the steady-flow tank by pressure detecting, guarantee the normal of tap water pipe network pressure.When rate of discharge during greater than inlet flow rate, the steady-flow tank liquid level can descend, and drops to certain low water stage position, water pump 12 shutdown of will delaying time, and with the safety of protection equipment, after water level recovered, water pump 12 resumed operation automatically.
The above specific embodiment only is used for explanation the utility model, but not is used for limiting the utility model, and the equivalent variations that those skilled in the art carry out above-described embodiment, replacement are all within the claim protection domain.
