Description

Pipe network pressure-superposed voltage stabilizing pressure maintaining tank
Technical field
The utility model relates to the secondary water supply systems, particularly a kind of pipe network pressure-superposed voltage stabilizing pressure maintaining tank such as intelligence such as water distribution system flushing.
Background technology
The air pressure tank used in the market, all based on early stage type design; This pneumatic water supply mode mainly relies on the volume of air pressure tank to a great extent, cushions the start-stop time of pump group, thus reaches the start and stop reducing pump group, relies on the effect of pressurized tank pressurize simultaneously; Along with the development of science and technology, the manufacturing technology of machinery, and the improving constantly of electronics technology, water pump performance has had the raising of leap, can not be per hour more than 8 times from the early stage number of starts, till now not free restriction; Early stage by air pressure maintenance constant pressure water-supply, feed water mainly through frequency conversion now; Make to become more and more less to the requirement of volume of pressure tank.By the restriction in place, present community secondary booster pump station is generally less than normal, and the vacuum tank of early stage large volume can not adapt to the requirement of current facility compact, thus has had stricter requirement to the volume of air pressure tank.
In addition, perfect in order to ensure without negative pressure (pipe network pressure-superposed) function, need to consider required in water supply process faced by each may, wherein have and a kind ofly seldom to occur in water supply, but the problem that may meet, namely equipment power-off or other reasons out of service suddenly; Now because water have accumulated very high potential energy in the duct, due to the unexpected stopping of equipment, water potential energy can produce water hammer, acts on pipe network and equipment conversely, can cause serious damage to pipe network or equipment, and causing cannot normal water supply.The water hammer cancellation element used in the market, is mainly piston water shock absorber; This water shock absorber is mainly arranged on pipeline, plays a protective role to pipeline, and piston absorber type selection calculation has very large associating with the length of pipeline, configures comparatively complicated.
Utility model content
The utility model provides a kind of pipe network pressure-superposed voltage stabilizing pressure maintaining tank playing pressure holding function in network pressure superposition water supply system.
For solving the problems of the technologies described above, the pipe network pressure-superposed voltage stabilizing pressure maintaining tank of the utility model, comprising: tank body, is provided with gas supplementing opening, is provided with opening in described tank base at described tank body top; Capsule, described capsule is arranged on the inner chamber of described tank body; Nitrogen is filled with in nitrogen chamber between described capsule and described inner tank wall; Intake-outlet, described intake-outlet is arranged on the bottom of described capsule, and described intake-outlet is communicated with described capsule; Described intake-outlet passes from described tank interior from described opening; The pressure of described nitrogen is the half of system maximum pressure.
The volume of described capsule is: in formula: Vq2 is the volume adjusted of described tank body; Qb is 1/10 ~ 1/20 of the outflow of pump group; α a is safety factor, gets 1.0 ~ 1.3; Nq is the number of starts of pump group in 1 hour, adopts 8 times ~ 15 times.
The volume of described tank body is: in formula: Vq is described tank body total measurement (volume); Vq1 is the water capacity of described tank body; α b is the operating pressure ratio in described tank body, adopts 0.65 ~ 0.85; β is the bulk coefficient of described tank body, gets 1.05.
The material of described capsule is EPDM.
The pipe network pressure-superposed voltage stabilizing pressure maintaining tank of the utility model, by equipment reasonably pressure buffer, not only meet and effectively eliminate water hammer, and by equipment reasonably pneumatic water supply, meet again small flow pressure maintaining feeding water function, in turn save the structure space of equipment simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, the pipe network pressure-superposed voltage stabilizing pressure maintaining tank of the utility model is described in further detail.
As shown in Figure 1, the pipe network pressure-superposed voltage stabilizing pressure maintaining tank of the utility model forms primarily of tank body 2, capsule 4, intake-outlet 6 and gas supplementing opening 1.Tank body 2 is for being arranged on outermost metal can, and tank body 2 is carbon steel material, and outside is antirust baking vanish layer or stainless steel 304 material.Capsule 4, for being arranged on the EPDM material inner bag within tank body 2, is nitrogen chamber 3 between capsule 4 and tank body 2, and precharge of gas (nitrogen) pressure is the half of system maximum pressure, and capsule 4 inside is full of the medium needing pressurize.Intake-outlet 6 is arranged on the bottommost of tank body 2, is connected with tank body 2 by flange, and directly connect capsule 4 with extraneous, gas supplementing opening 1 is arranged on tank body 2 top, is the access port of pre-inflated with nitrogen.Gas supplementing opening 1 is positioned at the top of tank body 2, inner employing movement mechanism; By gas supplementing opening 1 to nitrogen chamber 3 preliminary filling high pressure nitrogen, inner gas pressure controls according to 1/3 of equipment operating pressure.
Pipe network pressure-superposed special small flow pressure maintaining capsule 4 tank is connected with equipment pipe by intake-outlet 6, working media enters in water cavity 5 as inner in capsule 4 by pipeline, now pressure of supply water is equal with capsule 4 inner water cavity 5 internal pressure, because pump group pressure is greater than nitrogen chamber 3 internal pressure, inner space, nitrogen chamber 3 is constantly shunk, pressure is supercharging gradually, until equal pump group pressure, reaches pressure balance.When user without water is or water supply volume is less, by capsule 4 pressurize, or low discharge supplies water.Thus reach the function of small flow pressure maintaining.
Wherein, the volume of capsule 4 is: in formula: Vq2 is the volume adjusted of tank body 2; Qb is 1/10 ~ 1/20 of the outflow of pump group; α a is safety factor, gets 1.0 ~ 1.3; Nq is the number of starts of pump group in 1 hour, adopts 8 times ~ 15 times.
The volume of tank body 2 is: in formula: Vq is tank body 2 total measurement (volume); Vq1 is the water capacity of tank body 2; α b is the operating pressure ratio in tank body 2, adopts 0.65 ~ 0.85; β is the bulk coefficient of tank body 2, gets 1.05.
By equipment reasonably pneumatic water supply, both meet small flow pressure maintaining feeding water function, in turn save the structure space of equipment simultaneously.
In addition on the one hand, the pipe network pressure-superposed voltage stabilizing pressure maintaining tank of the utility model is connected with equipment pipe by intake-outlet 6, working media enters as in capsule water cavity 5 by pipeline, when equipment unexpected out of service time, medium in pipe network forms very large potential energy, potential energy is constantly converted into kinetic energy under gravity, produce water hammer thus, owing to being gas in nitrogen chamber 3, inner space, nitrogen chamber 3 is constantly shunk, is discharged, the pressure that water hammer produces is gradually consumed, until equal normal hydraulic pressure, reaches pressure balance.
Reached the function eliminating water hammer by pressurize, reach the function to water supply network or equipment protection.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
