Abstract
The utility model provides a semi-enclosed secondary pressurization water supply device. A seal valve which is used for opening and closing a whole water storage container in a linking and matching way is arranged on a top cover of the water storage container, or a bypass pipe which is connected with a water outlet pipe in parallel with a water pump and is provided with an electromagnetic valve is arranged on the water storage container. An electro connecting pressure gauge is arranged on the water storage container or the bypass pipe. The electromagnetic valve, the electro connecting pressure gauge, and a water level controller are connected with an electric control cabinet by electric circuits. A one-way valve is arranged on a water inlet pipe which is connected with the water storage container. The utility model has the advantages of novel structure, reasonable design, less investment, low energy consumption, and convenient operation. The utility model is a novel secondary pressurization Water supply device.
Description
The utility model relates to a kind of public waterworks, especially a kind of second pressure water supply device of water supply system.
In known technology, existing second pressure water supply device, mainly the open type second pressure water supply device of forming by water storage container, water pump assembly, float valve, one way valve, stop valve, water main, outlet pipe, leap pipe, water level controller and frequency conversion electrical control cabinet etc.Because existing second pressure water supply device is an open type, it is according to the water level of water storage container, water inlet pipe by float valve or electromagnetic valve sealing control water storage container, the vessel volume utilization rate is low, especially the once water supply of second pressure water supply and public feedwater piping disconnects fully, water storage container is that open type is in atmospheric pressure state, make a pressure of supply water energy all waste, and secondary water-supply need start equipment such as water pump and again the water at atmospheric pressure pressurization of water storage container reached setting pressure, it consumes energy high, investment is big, and the operation of need ceaselessly turning round of secondary pressurized equipment, in case have a power failure or equipment breaks down, just cause and to send water, make troubles to the user.
The purpose of the utility model provides a kind of improved second pressure water supply device, and it can cut down the consumption of energy greatly, reduces energy waste, make its novel structure, reasonable in design, investment is little, easy to use.
For achieving the above object, the technical scheme that the utility model is taked is: water level opens wide or seals the seal valve of whole water storage container, the semi-enclosed second pressure water supply device that consists of movingly in installing according to container on the water storage container top cover.Or again on water storage container installing connect the bypass pipe that has electromagnetic valve of outlet pipe mutually side by side with water pump, and on water storage container or bypass pipe the load electro connecting pressure gauge, electromagnetic valve is connected electrical control cubicles by circuit altogether with electro connecting pressure gauge, water level controller.During use, open valve on the public water supply pipeline to the water storage container inner water-supply.When inflow in the water storage container was less than or equal to water yield and is lower than designated water level, seal valve is in opening-wide state, and was identical with existing open type second pressure water supply device; When the inflow of water storage container during greater than water yield, water level rises to desired location, seal valve seals whole water storage container, continue to enter along with once supplying water and to make that hydraulic pressure rises gradually in the water storage container, when hydraulic pressure was less than setting pressure in water storage container, the secondary pressure pump only need be done the relay merit just can reach the setting water pushing pressure; Hydraulic pressure is raised to or when setting discharge pressure in water storage container, electro connecting pressure gauge on the water storage container is by the automatic conversion and control of electrical control cubicles, water-delivery pump is stopped, automatically open electromagnetic valve and open bypass pipe, directly send water to the water user by water storage container through bypass pipe by a pressure of supply water of common line.
Because the utility model has adopted the second pressure water supply device of semi-enclosed structure, can just control according to the inflow of water storage container and water yield and water level and open wide or the sealing water storage container, according to the hydraulic pressure in the water storage container by electrical control cubicles automatically conversion carry out that open type supplies water, the relay-type pressurization is supplied water, straight supplies water.It has novel structure, reasonable in design, save the energy, small investment, power consumption is low, service life of equipment is long, the installing seal valve has improved the water storage container capacity utilization greatly on the water storage container top cover, having a power failure or equipment breaks down not influence once under the situation and supplies water, easy to use, be a kind of novel second pressure water supply device.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model embodiment concrete structure diagrammatic sketch.
Embodiment as shown in Figure 1, this second pressure water supply device comprises: water storage container (1), seal valve, electro connecting pressure gauge (6), water level controller (7), water pump (2), back with water inlet line (11), water outlet pipeline (3), bypass pipe (4) and frequency conversion electrical control cabinet DKG.Load seal valve on the top cover of water storage container (1), seal valve opens wide or seals whole water storage container movingly according to the water level of water storage container.Seal valve is float-ball type seal valve or floating tongue formula seal valve or floating plug formula seal valve, and other type can be with the unsteady seal valve that cooperates or opened wide or sealed whole water storage container by electrical control cubicles control of the height of water level in the container.The seal valve load is on the maintenance hand-hole cage (9) of water storage container (1) top cover or on other reservation assembling apertures.Fig. 1 embodiment is that the float-ball type seal valve (8) that adopts is installed on the maintenance hand-hole cage (9) of water storage container (1) top cover.
The utility model has also been installed the bypass pipe (4) that is connected water outlet pipeline (3) side by side with secondary pressure pump (2) and is fitted with electromagnetic valve (5) on water storage container (1), installed electro connecting pressure gauge (6) on water storage container (1) or bypass pipe (4), electro connecting pressure gauge (6) is connected with frequency conversion electrical control cabinet DKG by circuit altogether with electromagnetic valve (5), water level controller (7).
In order to keep water storage container (1) internal pressure not reduce with a water supply line internal pressure, present embodiment is fitted with one way stop peturn valve (10) on the back with water inlet line (11) that water storage container (1) is connected.
For the water storage container that is shaped on pore of big volume, at its pore seat oral area load tubular sealed valve.
