Abstract

The characteristic lies in that it is composed of floating ball, non-return valve and cylinder body. When open the water pump to pour water in the cylinder, the non-ruturn valve is opened by the water flow, the water flows reversely from the non-return valve to gas pressure cylinder. When stopping water flooding, owing to the water in cylinder goes above the floating ball, under the action of buoyancy the non-return valve is opened to make the water in cylinder pass through the non-return valve with definite pressure to supply the user, when the buoyancy is less than the elastic force of the spring of the non-return valve, the non-return valve is closed immediately. So that the strucbure of the invented daily life and fire fighting water supply equipment is simple and practical.

Description

Full-automatic life, fire-fighting constant pressure water supply equipment

Current water supply, fire fighting equipment of a great variety mainly all is based on air pressure tank.That generally adopts has two kinds: a kind of is automatic gas compensating type, and a kind of is capsule formula (being barrier film).No matter which kind of one exists tangible drawback.

One, capsule formula equipment: because tank interior adopts a kind of rubber bag tank to make barrier film, capsule is wanted convergent-divergent every day in tank body, want one, 200 time at least, thus the life-span of a capsule generally about 1 year, just break down the half a year that has, capsule has been broken, gas will be run away, and air pressure tank just can not be worked, and need renew capsule again, need several thousand yuan and change a capsule, so very uneconomical.Just because of this, the inaccurate capsule formula equipment that adopts of fire-fighting pressure jar.

Two, tonifying Qi equipment: because equipment adopts full-automatic tonifying Qi, so its ancillary service more (as two of negative pressure water-absorbing tanks, air supply tank is two automatically, respectively four on aeration valve, vent valve, various flap valve, valve).Increasing of these attached links, not only cost is high but also cause increasing of fault rate.If there is link to handle bad or break down, equipment just can't turn round, and this equipment also be subjected to underground, the restriction of upper pool.If have a power failure, when cutting off the water, gas will all be run away.

Automatically tonifying Qi also has certain disadvantage in fire fighting equipment.As, when serving as fire fighting equipment, fire-fighting do not need at any time all stop, in service.So just not tonifying Qi automatically of tank body (will mend the optimum position to gas therebetween, approximately need thousands of operations, stop).So air pressure seldom in jar.Can not bring into play the real effect of air pressure tank.If run into power failure again, when cutting off the water, the gas in jar is run away together with water.Promptly in all drawbacks of above equipment, designed full-automatic life, fire-fighting constant pressure water supply equipment hereby, this device can be contained in the jar or outside the jar, disposable inflation can be used for a long time, does not promptly need capsule also not need other ancillary service.The gas that has a power failure or cut off the water can not run away, and has promptly solved the deficiency of supply equipment, has solved the deficiency of fire fighting equipment yet.

In conjunction with the accompanying drawings that principles illustrated is as follows: when open water pump (5) give jar in during water filling, flap valve (4) is opened by water, water reversely flows into air pressure tank from flap valve, in order to prevent the impact force of powerful current to ball float, above flap valve, establish current interceptor (3) for this reason, when water filling stops, because water did not have ball float (1) in jar, under buoyancy, flap valve (4) is opened (because of the displacement of ball float is buoyancy＞check-valve spring pulling force) and made that water supplies water to the user by flap valve with certain pressure in the jar.Operation so repeatedly, the gas in jar maintains the first half of tank body with certain pressure.When equipment had a power failure, water level continue to descend, when drawdown to ball float (1) when surfacing, buoyancy＜flap valve (4) spring tension of ball float (1).Flap valve (4) cuts out at once automatically.Current can not flow out, thereby the gas in the tank body is maintained in the jar reliably.Regulate ball float (1) in the position of adjusting rod (2), can determine the lowest water level in the tank body.

Said apparatus equipment automatic control cabinet is full-automatic life, fire-fighting constant pressure water supply equipment.This equipment is particularly useful for fire fighting supply.

Claims

The present invention is life, fire-fighting watering equipment, its feature: be made up of ball float, flap valve (or special-shaped flap valve), adjusting rod (and special-shaped adjusting rod), current interceptor.
