Abstract
The utility model provides a cavity-type water supply device which uses a cavity to simultaneously realize the functions of a water storage cavity and a pressure maintaining cavity, and consists of a multifunctional cavity, a vacuum suppressor, a control cabinet, a pressure maintaining pump, a water inlet butterfly valve, a water inlet bypass check valve, a booster pump, a water outlet bypass check valve, a water outlet butterfly valve, and a remote pressure gauge, wherein the pressure maintaining pump is a low-flow high-lift water pump; the water inlet butterfly valve is positioned in front of the device; the multifunctional cavity is provided with the vacuum suppressor; inlet water enters the multifunctional cavity through the pressure maintaining pump and the bypass check valves, then converges in front of the water outlet butterfly valve through the booster pump and the water outlet bypass check valve, and finally reaches a user pipeline through the water outlet butterfly valve; and the control cabinet is respectively used for controlling the operation of the pressure maintaining pump and the booster pump according to the collected signals of the remote pressure gauge.
Description
Technical field
The utility model relates to a kind of supply equipment, specifically, relates to non-negative pressure water-supply installation of realizing current stabilization and pressure holding function cavity simultaneously of a kind of use.
Prior art
At present, in known no negative pressure equipment, in order to realize stable water supply and low discharge pressurize, operated by rotary motion is established a pressurize chamber or similar device outside a bigger current stabilization chamber in addition.But this type of technical scheme has the following disadvantages: under the very unsettled operating mode of some water situations, be subjected to structural limitations, can cause water pump according to water situation frequent start-stop, reduced service life of equipment thus.And this class formation can cause the increase of contour size of the unit(s) and then cause cost to increase, and in addition, for the pump house space of present growing tension, increases the increasing that installation dimension can cause initial cost equally.
Summary of the invention
The utility model provides a kind of non-negative pressure water-supply installation that uses a cavity to realize water storage cavity and pressurize chamber function simultaneously at existing above-mentioned deficiency in the prior art.Its main purpose is realizing further making equipment integrated on the low discharge pressure holding function basis more effectively, cuts down finished cost and floor space is installed.
The purpose of this utility model is to realize like this, it comprises multi-functional cavity, vacuum suppresser, switch board, pressurize pump, water inlet butterfly valve, water inlet bypass check valve, force (forcing) pump, water outlet bypass check valve, water outlet butterfly valve and teletransmission pressure meter composition, and wherein the pressurize pump is the low-flow high-lift water pump.The water inlet butterfly valve is set before the equipment, on the multi-functional cavity vacuum suppresser is set, water inlet enters into multi-functional cavity through pressurize pump, bypass check valve respectively, respectively through force (forcing) pump and go out Water Check Valve and converge, arrives user pipe behind the water outlet butterfly valve then before the water outlet butterfly valve.Switch board is controlled pressurize pump and force (forcing) pump operation respectively according to the teletransmission pressure meter signal of collecting.
When intake pressure satisfied the direct-furnish demand, water inlet directly through water inlet bypass check valve, multi-functional cavity, water outlet bypass check valve, directly was fed to the user through the water outlet butterfly valve again; When discharge pressure can't be satisfied the demand, switch board control force (forcing) pump started, and the water in the multi-functional cavity is pressurized to required pressure is fed to the user, and simultaneously, vacuum suppresser starts, the generation of control negative pressure; When the intake pressure deficiency but user's water supply volume when very little, switch board control pressurize pump startup is fed to the user by its pressure of keeping in the multi-functional cavity with water.Because the pressurize pump is low-capacity pump, can not produce the negative pressure influence, and solve thus and need the low discharge state numerous start and stop problem of big pumping frequency in following time for a long time the front end pipe network.
The technical advantage of this programme is that pressurization operation and pressurize move a shared cavity, make device structure obtain having saved the equipment occupation of land, and makes the equipment operation more stable.Because the pressurize pump power is very little, has reduced running cost equally, has saved user's fund.
Description of drawings
Accompanying drawing (1) is the structural representation of an embodiment of the utility model.
The specific embodiment
Connect water inlet butterfly valve (11), pressurize pump (3), multi-functional cavity (10), force (forcing) pump (6), water outlet butterfly valve (8) successively with pipeline, before pressurize pump (3) water inlet with between multi-functional cavity (10), be connected in series water inlet bypass check valve (12), serial connection water outlet bypass check valve (7) between the delivery port of force (forcing) pump (6) and multi-functional cavity (10).Go up installation vacuum suppresser (2) at multi-functional cavity (10), teletransmission pressure meter (4) is installed in force (forcing) pump (6) water side.
Its working method is: when intake pressure satisfied the direct-furnish demand, water inlet directly through water inlet bypass check valve (12), multi-functional cavity (10), water outlet bypass check valve (7), directly was fed to the user through water outlet butterfly valve (8) again; When discharge pressure can't be satisfied the demand, switch board (1) control force (forcing) pump (6) started, and the water in the multi-functional cavity (10) is pressurized to required pressure is fed to the user, and simultaneously, vacuum suppresser (2) starts, the generation of control negative pressure; When the intake pressure deficiency but user's water supply volume when very little, switch board (1) control pressurize pump (3) starts, and by its pressure of keeping in the multi-functional cavity water is fed to the user.And the pressure data that switch board (1) is gathered according to teletransmission pressure meter (4) switches between three kinds of states.
Claims (4)
1. cavate supply equipment, mainly form by multi-functional cavity (10), vacuum suppresser (2), pressurize pump (3), force (forcing) pump (6), water inlet bypass check valve (12), water outlet bypass check valve (7), switch board (1), water inlet butterfly valve (11), water outlet butterfly valve (8), teletransmission pressure meter (4), it is characterized in that: vacuum suppresser (2) is installed on the multi-functional cavity (10), and pressurize pump (3) and force (forcing) pump (6) are connected on the water inlet end and the water side of multi-functional cavity (10) respectively.
2. a kind of cavate supply equipment according to claim 1 is characterized in that: between pressurize pump (3) water inlet end and multi-functional cavity (10) the water inlet bypass is set.
