Description

Pressure-creasing device made of multi-purpose joint and pressure-head

The utility model relates to a kind of pressurization device, particularly a kind of water supply pressurization device that is made of multipurpose joint and pressure pot.

At present, no matter in cities and towns or the rural area, the supply rate of tap water is more and more universal, build higher and higher and build a house, because water resources lacks and the increase of high-rise, the water pressure deficiency has become a major issue, and especially the phenomenon of hydraulic pressure deficiency is of common occurrence when water use peak.Therefore, tall building is many realizes pump water with the driven by motor suction engine, the perhaps multistage many pump feedwater of segmentation.The existing problem of this water supply installation is as follows:

1, because the joint that suction engine (water pump) is connected has only a water outlet, therefore, the direction and the position of the outlet pipe that is connected with water outlet are subjected to significant limitation, can't do flexibly because of different device spaces and water supply direction and adjust, and have brought very big inconvenience to installation.

2, when water outlet with after water-filled pipe is connected, its length, position are all fixing, can't shift one's position and connect and use distance, then must water pipe is sawed-off or water pipe that socket length again is different, both time-consuming, labor intensity is also bigger.

3, joint is enclosed, when its inner residual unnecessary air is arranged or the assorted bits that drop when connecting water pipe after, not only inconvenience is got rid of, and easily causes the obstruction of pipeline, causes water supply not smooth.

4, inconvenient maintain and replace also can't show water supply pressure.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and provides a kind of installing space to adjust and to exchange, and unloads and changes the pressurization device that is made of multipurpose joint and pressure pot easily.

The purpose of this utility model is to realize by following technological scheme: constitute a hollow container by last lower barrel body make-up, clamping has an elastic membrane pad at staving buckling surface place, twist in lower barrel body bottom adapter place and to be connected with flange and to be connected with multipurpose joint, multipurpose joint circumferentially is provided with several outer separately adapters of visiting, multipurpose joint bottom and its circumferential opposite side and above all offer interface, multipurpose joint inside is equipped with safety check and spring, the outer spy in the adapter is connected with Decompression valves respectively, pressure gauge and pressure switch, each interface can connect to need to exchange by reality to be used.

Therefore: remarkable result of the present utility model is:

1, because upper interface and its circumferential interface are used interchangeably, thereby the direction setting of put, installation and water outlet being taken over provides convenience.

2,, thereby make installations, overhaul all comparatively laborsaving saving time because each interface position all is provided with the flange of being convenient to roll over dress as to pipe fitting.

3, pressure gauge, Decompression valves can guarantee the Security of pressurization device use and the demonstration directly perceived of internal pressure.
