Abstract

The utility model provides a no negative pressure water supply instrument without air pollution, which mainly comprises a tank body, a bag, a water pump, an automatic control cabinet, a liquid level sensor, a pressure sensor, a check valve, etc. The technical proposal of the utility model lies in that a bag type reservoir structure design is adopted, the air of a complementary system is completely isolated from water by the bag, and the air and the water are not contact any longer. The utility model not only does not generate negative pressure, but also avoids the water quality pollution by the air, and thereby, the goal of the utility model is realized.

Description

No air-polluting non-negative pressure water-supply installation

Technical field

The utility model relates to a kind of building water supply equipment, particularly relates to a kind of supply equipment of realizing no negative-pressure pipeline pressurization by water pump.

Prior art

In order to solve the problem that municipal tap water pressure can not well satisfy high building water needs, disclose a kind of nothing for Chinese patent ZL97245178.1 number and inhaled journey piped water equipment unit, a kind of non-negative pressure method of water supply device is disclosed for ZL00256147.6 number, a kind of energy-conservation no negative pressure storage tank is disclosed for ZL01204960.3 number, the advantage of these equipment is directly to be serially connected in draws water on the pipe network of municipal tap water and can not produce negative pressure in city planting ductwork, both utilized the pressure in the pipe network, the water pollution of having avoided original pond way of supplying water to bring again is the effective way that solves building water supply really.

But, because above-mentioned utility model has all adopted the method that covers air in system for fear of producing negative pressure, and the direct contact mixed with water of the air that covers, so just still inevitably water quality is produced air pollution.

Goal of the invention of the present utility model is to provide a kind of can overcome the defective that above-mentioned technology exists, simple in structure, neither produces negative pressure, can not produce any air-polluting non-negative pressure water-supply installation again.

Goal of the invention of the present utility model is achieved in that the utility model has adopted capsule formula reservoir structure design, by capsule the air and the water that cover is isolated fully, never contact, thus avoided the pollution of air to water quality, realized the purpose of invention.

The specific embodiment

Below with reference to above accompanying drawing, the specific embodiment of the present utility model is done further detailed description.

Referring to Fig. 1, capsule (3) is housed in the tank body (2), capsule is made by rubber or other resilient material; In tank body (2), capsule (3) has formed a cavity A, formed cavity B between capsule (3) and the tank body (2), breather (5) is housed on tank body (2), breather (5) can be contained in any one position of tank body (2), one or more holes (6) are arranged on the breather (5), have a plurality of holes (4) to be connected between breather (5) and the tank body (2), B chamber and atmosphere are in communicating state all the time; Also can not adorn breather (5) on the tank body (2) and directly communicate with atmosphere by hole (4), hole (4) can be in communicating state as long as guarantee B chamber and atmosphere all the time in arbitrary position of tank body (2); In the bottom of capsule (3) liquid level sensor (11) is housed, liquid level sensor described herein (11) comprises all instruments that liquid level signal can be provided, as content gauge, liquid-level switch, various liquid level sensor, liquid level sensor (11) is connected with lead (13) through sealing (9) by lead (10); On the pipeline of delivery port (7) or water inlet (1), teletransmission pressure meter (8) is housed, flap valve (22) is housed on the pipeline that water inlet (1) is located, delivery port (7) is connected with the water inlet (20) of water pump (19), the water inlet end of flap valve (21) is connected with the water inlet (20) of water pump (19), and the water side of flap valve (21) is connected with the delivery port (18) of water pump (19); Delivery port at water pump (19) is equipped with gate valve (17) and flap valve (16), and teletransmission pressure meter (15) is housed on outlet conduit, and each teletransmission pressure meter, liquid level sensor, water pump all are connected by lead with automatic control cabinet (14).

In user's constant-pressure water feeding system process, the water in the city planting ductwork enters supply equipment by water inlet (1) in automatic control cabinet (14) control of pump (19).

When flow of inlet water during greater than the water supply flow of equipment, unnecessary water will replenish by Nang Kou (12) and enter the A chamber, capsule (3) is expanded, at this moment the air in the B chamber will enter atmosphere by hole (4) and breather (5), expand into the inwall of tank body (2) until capsule (3) and to contact, moisturizing process is so far finished.

When flow of inlet water is zero less than the water supply flow of equipment or flow of inlet water, water in the capsule (3) will replenish the pipeline that enters water pump (19) by Nang Kou (12) and delivery port (7), satisfy user's water with the deficiency that remedies the city planting ductwork output, the effect of flap valve (22) is to avoid the aqueous reflux in capsule (3) and the supply equipment to return city planting ductwork; Water is flowed out by capsule (3), and the A chamber is shunk, and at this moment ambient atmosphere will enter in the B chamber by breather (5) and hole (4), is not less than atmospheric pressure to guarantee the pressure in B chamber and the A chamber, does not promptly have negative pressure; In the contraction process of capsule (3), liquid level wherein can descend thereupon, when liquid level is reduced to certain position, liquid level sensor (11) reaches automatic control cabinet (14) with signal by lead, after automatic control cabinet (14) is handled signal automatically with Pump Failure, water pump (19) is shut down no longer draw water, cause damage to avoid producing negative pressure and the anhydrous idle running of water pump (19); Also can realize above-mentioned functions with teletransmission pressure meter (8) separately: the pressure in equipment is reduced to certain value, and teletransmission pressure meter (8) can reach automatic control cabinet (14) with a signal of telecommunication equally, water pump is shut down, and do not produce negative pressure and damage water pump.

Referring to Fig. 2, this is one of tank body and capsule form of structure.This structure is a horizontal type structure, and there is Nang Kou (23) at the middle part of capsule (3), and capsule (3) is contained in the horizontal tank body (2).
