Abstract
The utility model discloses non-negative pressure water supply equipment characterized by comprising a water storage pot body (11) which is composed of a municipal pipe network joint, a middle pipeline, edge pipelines distributed on two sides of the middle pipeline, a wafer check valve (24), an automatic control valve (26), a wafer butterfly valve (18), a wafer butterfly valve (7), a winding connector (6), a eccentric reducer (5), a multi-stage centrifugal pump (4), a winding connector (3), a mirror check valve (1), a wafer butterfly valve (2) and an intelligent vacuum shunt device (29) arranged at the bottom of the pot body. The middle pipeline is led out through a four-way pipeline (8), the middle pipeline and the two edge pipelines are gathered at a user water supply pipeline (25), and the wafer check valve (24), the automatic control valve (26) and the wafer butterfly valve (18) are sequentially installed on the middle pipeline. The wafer butterfly valve (7), the winding connector (6), the eccentric reducer (5), the multi-stage centrifugal pump (4), the winding connector (3), the mirror check valve (1) and the wafer butterfly valve (2) are sequentially disposed on the edge pipelines. The non-negative pressure water supply equipment is low in manufacturing cost and convenient to install, and the pot body can be effectively protected through the intelligent vacuum shunt device.
Description
Technical field
The utility model relates to a kind of no-negative-pressure water supply equipment.
Background technology
No-negative-pressure water supply equipment is connected in the tap water city planting ductwork usually, but the structure design of the no-negative-pressure water supply equipment of prior art is very unreasonable, and cost is higher.No-negative-pressure water supply equipment can be given user's normal water supply under the driving of water pump, but water storage tank body middle water level then can appear in the insufficient water of city planting ductwork is released to lower water level, cause the water storage tank body vacuum state to occur, then can't give user's normal water supply, and, degree is more near ultimate limit state under the water storage tank body middle water level, and then this vacuum state is more serious, and is also bigger for the infringement of water storage tank body.
Summary of the invention
At above shortcomings in the prior art, the utility model provides a kind of no-negative-pressure water supply equipment.
To achieve these goals, the utility model adopts following technical scheme:
A kind of no-negative-pressure water supply equipment is characterized in that, has:
Water storage tank body (11), it has the city planting ductwork interface and the intermediate conduit that picks out by four-way pipeline (8) and the edge pipeline that is distributed in the intermediate conduit both sides, and described intermediate conduit and two edges pipe influx are in user's feedwater piping (25);
Be installed on successively intermediate conduit to folder flap valve (24), automatic control valve (26), wafer type butterfly valve (18);
Be installed on successively the edge pipeline to folder butterfly valve (7), around property joint (6), eccentric reducer (5), centrifugal multistage pump multiple centrifugal pump (4), around property joint (3), minute surface flap valve (1), to folder butterfly valve (2);
Be installed on the intelligent vacuum part flow arrangement (29) of tank base.
Described user's feedwater piping (25) is equipped with teletransmission pressure meter (16) by I.S.S ball valve (17).
The bottom of described water storage tank body (11) is equipped with draining valve (20).
Described intelligent vacuum part flow arrangement is vacuum suppresser.
Compared to existing technology, the utlity model has following advantage:
(1) overall cost is low, and is easy for installation, and effectively protects for tank body by the intelligent vacuum part flow arrangement.
