Abstract

The utility model discloses a pneumatic flushing device which is composed a box body, a valve body (8), an anti-return device, an air make-up device, a discharge water device, a flushing device and a water-air mixture device. The tubing pressure of the liquid is conducted to store through an energy storage hollow chamber. When a bolt (11) or an external bolt (13) is pressed, the instantaneous internal pressure of a piston chamber vanishes; a flushing valve is opened, and the liquid conducts to flush the flushing objects with continuous pipe pressure; the pneumatic flushing device has advantages of small consumption and large flushing force. Meanwhile, a bulkhead safety device is especially designed in order to prevent the tubing pressure from overtopping and the danger of explosion from generating, and the people oriented human centered design is verily done.

Description

Air pressure bath device

One, technical field

The utility model relates to a kind of novel air pressure bath device for building, and it can be widely used in buildings such as residential modern, office block, hotel and various public places.

Two, technical background

The employed bath device of existing building generally is divided into two kinds.One, gravity type are that water tank is hung in height, and produce impulse force by the water level discrepancy in elevation, but very water wasting of the method.Its two, the air pressure type flushing device, it is a general accumulation of energy cavity, and the pipe of tap water is compressed into row storage, when opening valve, tap water washes with the continuous pipe pressure washing that liquidates.But all air pressure bath devices air pressure occurs and leak at present, and the water that causes in the casing can't drain, and after the use for several times, water is cumulative, causes fills with water in the water tank, loses pressure, has just lost the air pressure flushing function.

Three, technology contents

The purpose of this utility model provides a kind of air pressure bath device, it is a general accumulation of energy cavity, the pipe of tap water is compressed into the row storage, when opening valve, tap water washes with the continuous pipe pressure washing that liquidates, advantages such as the big and water yield of impulse force was little when it can guarantee to use guarantee that simultaneously the water in each water tank all can drain, realize each action after, all can make zero, start anew, guaranteed the reliability of action, and possess Quan Chong and half towards function.Be provided with simultaneously safely, cut off the water supply pressurize and gas-vapor mix apparatus function, really accomplish the human oriented design that people-oriented.

Concrete technical scheme of the present utility model:

A kind of air pressure bath device, by casing, valve body, backflow proof, tonifying Qi, discharge water, bath and gas-vapor mix device form.Casing is to be made of upper shell and lower house, and drowning bar is inserted in the casing by a via hole of upper shell.A via hole of crossing the water bar and being by upper shell inserts in the casing, and links to each other with following air port on being contained in lower house, and the liquid of crossing in the water bar does not directly communicate with the liquid of casing, is fed directly in the casing by the liquid in the drowning bar.Valve body is fixed on the upper shell, at valve body and casing contact position seal is housed;

Back-flow preventer is to be made of backflow proof guard shield, pressurize piston, elastic component, core print seat.The backflow proof guard shield is to be contained on the valve body, and the core print seat of dribbling also is housed in the backflow proof guard shield, pressurize ball and seal is housed on the pressurize piston, and is pressed in the valve body by elastic component.Core print seat compresses elastic component, thereby guarantees the pressure of liquid in the pressurize piston.When outside release, prevent from fully to lose bath pressure because of liquid refluxes.When hypertonia, the resistance that the pressure in the casing overcomes elastic component promotes to move behind the pressurize piston, the rear port of pressurize this moment piston with the backflow proof ball tightly get lodged in water inlet, guarantee safety;

Making-up air device is to be made of tonifying Qi core, tonifying Qi nut.The tonifying Qi core is contained on the valve body by the tonifying Qi nut.Its gas compensation function after finishing of realizing discharging water thoroughly drains water;

Jettison gear is to be made of inner screw, external screw rod, elastic component, needle, little screw plug, axle sleeve, big plug.Inner screw puts elastic component and seal and passes external screw rod and pack in the little screw plug.In the little screw plug needle is housed.External screw rod puts elastic body and seal and passes axle sleeve and pack in the big plug.Axle sleeve is installed in the valve body, and axle sleeve is equipped with seal.Switch pressure hook hook with switch pressure hook crawl inner screw and external screw rod respectively, can be realized Ban Chong and entirely towards function on valve body.

Flushometer is to be made of bath piston rod, elastic component, plug, bath piston.Elastic component is equipped with in bath piston rod inboard, and bath piston rod link is equipped with seal.Plug is housed on the elastic component, and the bath piston is connected with the bath piston rod thread.Whole flushometer inserts in the upper shell and matches with the following air port of lower house.When switch pressure hook crawl inner screw or external screw rod, the pressure fluid of bath in the piston communicates with atmosphere, and pressure moment is zero, and the bath piston moves up together with the piston rod of washing by water, and flush port is opened.When the hypertonia in the casing, liquid flows into by the plug that has elastic component and is rinsed container, guarantees safety.

The utility model is by an accumulation of energy cavity, the pipe of liquid is compressed into the row storage, when pressing inner screw or external screw rod, the liquid in the bath piston communicates moment plunger shaft internal pressure vanishing by crossing the water bar with following air port, the piston of washing by water simultaneously moves up, flushing valve is opened, and at this moment, liquid washes with the pipe pressure that the continues washing that liquidates, it has the advantage that consumption is little, impulse force is big, realizes this time making zero after the action.This moment in the plunger shaft surplus pressure and plunger shaft in the deadweight of water, force piston to move down, just blocked and airtight delivery port.Liquid is entered in the casing by back-flow preventer.When treating that pressure in the casing and pipe pressure are consistent, stop into water in the casing, enter dormant state, thereby finished a working cycles.Simultaneously for prevent pipe press too high, the danger of blasting, specialized designs the plug safety device.This air pressure bath device is really accomplished the human oriented design that people-oriented.
