Abstract

Disclosed is a water storage type non-negative-pressure water supply facility. The water storage type non-negative-pressure water supply facility is characterized in that a municipal pipe is connected with a flow stabilizing tank through a water inlet pipe, a brake valve, and a municipal pipe pressure sensor and a filter are arranged on the water inlet pipe; an automatic vent valve, a tank body pressure sensor and an automatic air suction valve are installed on the top of the flow stabilizing tank, and a blow-down valve is arranged at the bottom of the flow stabilizing tank; one end of a water outlet pipe is communicated with the flow stabilizing tank, a pump set is installed between the water outlet pipe and a user side water pipe, the water inlet end and the water outlet end of the pump set are each provided with a brake valve, a check valve and a flexible connecting pipe, and a teletransmission pressure sensor and an electric connecting pressure gauge are installed on the user side water pipe. According to the water storage type non-negative-pressure water supply facility, the occupied area is small, municipal water supply pressure during water peak is decreased, and stored water can be pressurized to the user side to achieve water yield compensation; the check valves are arranged at the two ends of the pump set, so that the phenomena that pressure water at the pressure water end backflows, the pump set rotates reversely and pressure inside the tank body is suddenly increased due to the fact that the check valve at the water outlet end loses efficacy are avoided; the automatic vent valve and the automatic air suction valve on the tank body are installed independently, so that safety and reliability are achieved.

Description

Storage-type no-negative-pressure water supply equipment
Technical field
The present invention relates to a kind of storage-type no-negative-pressure water supply equipment.
Background technology
No-negative-pressure water supply equipment utilizes city planting ductwork overbottom pressure to supply with it, keeps the sanitary of water sources not by secondary pollution and reduces the extensive accreditation that the advantage such as equipment investment cost and floor space obtains market.But along with the increasing of use amount, also the flow of city planting ductwork can be caused unbalance, especially the peak water period more exacerbates imbalance between supply and demand, and municipal pressure also only can improve in various places Running-water Company and strengthen supply flow rate, the adverse consequences caused is that Running-water Company constantly checks for this reason, namely strengthens water factory's pump group power.
Summary of the invention
Object of the present invention is just to provide that a kind of structure is simple, floor space is little, the storage-type no-negative-pressure water supply equipment of dependable performance.
Storage-type no-negative-pressure water supply equipment of the present invention, comprise gate valve, switch board, pump group, steady-flow tank, water inlet pipe, outlet pipe, user side water pipe, it is characterized in that, city planting ductwork is connected with steady-flow tank by water inlet pipe, water inlet pipe is equipped with gate valve, municipal ductwork pressure sensor and strainer; Automatic air valve, tank body pressure sensor and automatic air intaking valve are installed in steady-flow tank top, are provided with blowoff valve bottom steady-flow tank; Outlet pipe one end is communicated with steady-flow tank, installation pump group between outlet pipe and user side water pipe, and the water-in and water-out two ends of pump group are equipped with gate valve, flap valve and flexibility connection pipe, user side water pipe are equipped with remote transmission sensor and electro connecting pressure gauge; Municipal ductwork pressure sensor, tank body pressure sensor, pump group, remote transmission sensor and electro connecting pressure gauge are all by wire Access Control cabinet.
The operating principle of storage-type no-negative-pressure water supply equipment of the present invention is, water inlet pipe is introduced by city planting ductwork, after total gate valve is opened, municipal administration water enters steady-flow tank, in tank, water level ascending water pressure raises, and read current pressure values from tank body pressure sensor, in tank, air is compressed, when pressure is increased to automatic air valve higher limit, automatic vent valve events is vented; And when producing negative pressure in tank, and reach the action of automatic air intaking valve higher limit timer, eliminate negative pressure.By Running-water Company and relevant regulations, can starting device during municipal Ya Li≤0.20Mpa, as <0.20Mpa; under-voltage signal is learnt, equipment automatic shutdown protection, equipment alarm by tank body pressure sensor; after pressure recover, stoppage protection is removed, and automatically runs.Remote transmission sensor on user side water pipe and electro connecting pressure gauge, real-time transmission of pressure signal, control pump class frequency, realizes immediately regulating.Blowoff valve on the downside of tank body, can periodical blowdown, and because being press water in tank, only need to open valve, inside deposition silt can be discharged with press water, without the need to manual cleaning.
Storage-type no-negative-pressure water supply equipment of the present invention, compared with water tank or pond, floor space is little, and whenever the water use peak period, municipal water supply pressure drop, during underfed, can be forced into user side by deposit water by pump group, realize the water yield and compensate.Which eliminate supercharging return duct, and arrange flap valve at the two ends of pump group, prevent water side flap valve and lost efficacy, cause setting-out end pressure aqueous reflux, pump group is reversed, the phenomenon of increased pressure in tank body; On tank body, automatic air valve, automatic air intaking valve are independently installed, safe and reliable.
