Abstract
The utility model provides a vertical bypass pipeline for integrative water supplying equipment without negative pressure, which mainly comprises integrative water supplying equipment, a gate valve, a check valve, a filter, a flexible connector, etc. The utility model has the technical scheme that on the basis of an integrated structural design, a bypass pipeline is arranged outside the equipment; the selection of pressure of flow quantity of a valve element of the bypass line satisfies requirements of pressure of flow quantity of the equipment. When the equipment does not work or is maintained, the utility model uses the bypass pipeline to supply water for users and ensures the water supply of users. The bypass line is suitable for the integrative water supplying equipment without negative pressure. A water inlet and a water outlet of the integrative water supply equipment without negative pressure are positioned on one side.
Description
Technical field
The utility model relates to a kind of water supply facilities bypass line that inserts in the high building pipe network system, particularly relates to a kind ofly realizing the no negative-pressure pipeline incorporate water supply facilities bypass line that pressurizes by water pump.
Prior art
A kind of no negative-pressure pipeline pressurization integral intelligent water supply facilities is disclosed for Chinese patent ZL01244312.3 number, this equipment carries out Highgrade integration and integrated with cover body, electrical control gear and pressure water tank, its bypass line also is integrated in pressure water tank inside, and its advantage is that cost is low, pipe network is not produced negative pressure, installation and maintenance convenience etc.
But above-mentioned utility model still has the following disadvantages, the first, and bypass line is located at pressure vessel inside, the equipment maintenance of breaking down, the user cuts off the water, and the second, the bypass line caliber is little, can only realize the bypass line function, can not meet the demands during big flow.
Goal of the invention of the present utility model is to provide a kind of can overcome the defective that above-mentioned technology exists, add horizontal bypass line in the outside of equipment, remove the internal bypass pipeline, when equipment is not worked, tap water supplies water for the user by bypass line, when equipment breaks down maintenance, do not influence the user and supply water.Bypass line valve pipe fitting flow pressure selects to satisfy the flow pressure requirement of equipment, when equipment is not worked, utilizes bypass line can satisfy the requirement of user's water.
Goal of the invention of the present utility model is achieved in that the utility model is on the basis of original integrated structure design, between the outside water inlet of equipment and delivery port, increase gate valve and flap valve, between link up with pipeline, and valve pipe fitting flow pressure selects to satisfy the flow pressure requirement of equipment.When equipment is not worked, the gate valve on closing device water inlet and the water outlet pipeline, equipment is user's water supply as usual by bypass line, and can guarantee the requirement of user's water flow pressure, thereby has realized the purpose of invention.The present invention is applicable to that the water inlet of equipment and delivery port are at homonymy.
Description of drawings
Accompanying drawing is a system schematic of the present utility model.
1. gate valve; 2. strainer; 3. integrated water supply facilities; 4. gate valve; 5. connecting hose; 6. flap valve; 7. flap valve; 8. gate valve.
The specific embodiment
Below with reference to above accompanying drawing, the specific embodiment of the present utility model is done further detailed description.
Integrated water supply facilities (3) water inlet front end is equipped with gate valve (1) and strainer (2), and the end of delivery port is equipped with gate valve (4) connecting hose (5) and flap valve (6); Flap valve (7) and gate valve (8) are housed between gate valve (1) and gate valve (4).
The implementation procedure of equipment; When the delivery port pressure of equipment during less than setting pressure, device power-up, tap water enters integrated water supply facilities (3) by gate valve (1) and strainer (2), and tap water enters gate valve (4) connecting hose (5) and flap valve (6) by the delivery port of equipment after the process pressurization in equipment; Feed to the user at last.
When the delivery port pressure of equipment during greater than setting pressure, equipment downtime, tap water enters gate valve (8) by flap valve (7), through connecting hose (5), flap valve (6); Feed to the user at last,
When equipment breaks down maintenance, equipment downtime, the gate valve (1) of closing device water inlet front end, the terminal gate valve (4) of delivery port is pulled down maintenance of equipment, and tap water is introduced into flap valve (7), process gate valve (8), connecting hose (5), flap valve (6); Feed to the user at last, utilize bypass line to guarantee that the user supplies water.
Claims (5)
