Abstract

A water tank with air pressure capable of being increased mainly aims to solve the problem that at a place without unified tap water supply, water pressure is low due to the fact that the arrangement height of a water tank is insufficient. Air is pumped into the sealed water tank, the air pressure of the upper portion in the water tank is increased, and when the water amount is reduced to a certain degree, the increased air pressure is automatically removed, and then water pumping is carried out. When the water amount reaches the needed water amount, a water pump stops moving, the water tank is sealed, air pumping and pressure increasing are carried out, and the air pressure in the water tank is automatically kept in the water using process.

Description

A kind of water tank that adds air pressure

Technical field

The present invention relates to a kind of water tank that adds air pressure.

Background technology

In the unified place of supplying with tap water, people generally draw water by electronic suction pump from water head sites such as wells, are extracted into the water tank that is placed in roof or higher position and store, and then from water tank, draw water pipe, carry out water.But this mode of occupation has also been brought some drawbacks, one is to be subject to water tank that the restriction of height is set, particularly the building in place, a lot of rural area is generally one to two-layer, the height that water tank arranges generally can be over 10 meters, this can make water below Stall, the pressure of water is obviously inadequate, is particularly difficult to promote the electric equipment of the higher hydraulic pressure of needs such as gas water heater.Although it is higher that some arranges water tank, the above roof in Ru San Lou Si building, but this has brought again another problem, the difficulty of drawing water along with the increase of height also increases, except increasing the load of water pumper, the long-term operation of water pumper has also been proposed to harsher requirement, and some water pumper even cannot be worked.In order to address this problem, once had some technology to carry out piping pressurization, but owing to being subject to the capacity limitation of auto levelizer, these devices are frequent start-stop in water utilizing process often, has increased environmental noise before, also easy damage device motor has also increased energy consumption simultaneously.These problems are all given the ununified local masses that supply with tap water and have been brought a lot of inconvenience.

Summary of the invention

The present invention causes hydraulic pressure problem on the low side in order to solve in the ununified place of supplying with tap water because water tank arranges insufficient height.

The way that the present invention takes is exactly mainly to inflate in the water tank of sealing, increase water tank internal upper part air pressure, and at discharge reduction to a certain extent time, automatically cut added air pressure, then draw water, when the water yield reaches institute's water requirement, water pumper stops action, tank seal the pressurization of inflating automatically keep water tank inner air pressure in water utilizing process.

The present invention includes water tank, tank seal lid, inflate pressure inlet, decompression gas bleeder valve, water inlet pipe, outlet pipe, control supercharging decompression float and switch, control pumping motor float and switch, blowoff valve and foot rest.Water tank can suitably be thickeied or reinforce on existing commercially available stainless steel water box foundation, between tank seal lid and water tank, available rubber ring seals, seal cover can be by the rotary buckle form of buckle or similar pressure cooker type, water inlet pipe, the pressure inlet of inflating all adopts one-way sealing valve to connect, controlling supercharging decompression switch is double-throw formula, control pumping motor switch and can be single-way switch, decompression gas bleeder valve adopts solenoid-operated switch, when circuit communication, reduce pressure gas bleeder valve in opening state, when circuit disconnects in off status, decompression gas bleeder valve can carry out pressure release when pressure exceeds setting.Pump adopts conventional pump, preferably adopt oilless pump, can be with gasholder, also can not be with gasholder, pump with gasholder is controlled the start and stop of pump by gasholder inner air pressure sensor, be not with gasholder, air pressure probe be arranged in water tank in order to control the start and stop of pump.Water pumper adopts conventionally form.

During use, water tank is arranged on to roof or higher position, connects Pipeline and pump, water pumper, seal cover is buckled well.Open water pumper electric brake, plus-minus air pressure control electric brake, at this moment in water tank, do not have water, control pumping motor switch in connection status, control supercharging decompression switch in the connection of decompression gas bleeder valve, supercharging pump off-state, the gas bleeder valve that at this moment reduces pressure is opened, is started to draw water.When water arrives liquid level 17, control pumping motor switch in off-state, control supercharging decompression switch in the disconnection of decompression gas bleeder valve, supercharging pump connection status, at this moment the gas bleeder valve that reduces pressure cuts out, stops pumping, supercharging pump is communicated with power supply and starts working, when water tank internal gas pressure reaches setting value, by air pressure probe, control pump and quit work.In water utilizing process, along with the minimizing of quantity of water in water tank, when air pressure reduces, by air pressure probe, control pump and inflate, while reaching authorized pressure, stop inflating, to keep water tank inner air pressure balanced.

In water utilizing process, along with the minimizing of quantity of water in water tank, liquid level constantly declines, when liquid level arrives 16, control supercharging decompression switch in the connection of decompression gas bleeder valve, supercharging pump off-state, the gas bleeder valve that at this moment reduces pressure is opened, pump deenergization quits work, and starts decompression and loses heart.When liquid level arrives 15, control pumping motor switch in connection status, start to draw water.When liquid level arrives 17, repeat above step.

Liquid level

15,16,17 can be adjusted by adjusting float lifting rope distance, and liquid level 15, liquid level 16 are comparatively approaching, decompression is just completed and starts to draw water.Liquid level more than 17 leaves certain space, to account for 1/5 to 1/3 being advisable of volume of whole water tank.Pressurized air pressure is advisable with 0.15 MPa ~ 0.7 MPa.

By water tank is increased to air pressure, make water tank can be arranged on second floor Huo San building roof and be even arranged on ground and also can normally use, and obtain higher hydraulic pressure, effectively solved the problem of the local water inconvenience of obstructed tap water.
