Abstract
The utility model discloses an installing structure of a vertical type multistage centrifugal pump orifice flange, including an orifice, an orifice flange is arranged on the orifice, the orifice flange is sleeved on the orifice, an external notch is arranged on the external wall of the orifice, a clasp is clamped in the external notch, the clasp protrudes out of the external notch; the inner wall of the orifice flange is provided with an internal notch, and the internal notch clamps the inner side of the part of the clasp, which is protruding outside the external notch. The installing structure provided is simple in structure, the split type connection structure between the orifice flange and the orifice greatly simplifies the machining technology of the water inlet and outlet section; the orifice flange can be rotated into any angles in the circumferential direction, and any of the orifice flanges having the same aperture can be installed on the orifice, thereby greatly facilitating the installation of the vertical type multistage centrifugal pump.
Description
Technical field
The utility model relates to vertical multi-stage centrifugal pump, relates in particular to the mounting structure of vertical multi-stage centrifugal pump nozzle flange.
Background technique
Vertical multi-stage centrifugal pump is a kind of vertical multistage medium transport equipment; With its compact structure, characteristics such as volume is little, efficient is high, beautiful shape, installation floor space are little, be widely used in the systems such as boats and ships, airport, cleaning, ultrasound, printing and dyeing, chemical industry, boiler, water treatment, high rise building water supply and factories and miness plumbing.Vertical multi-stage centrifugal pump mainly comprises: the pump housing and motor two-part; Pump housing bottom is provided with base, and base is provided with water inlet-outlet segment, is respectively arranged with nozzle flange on the entry mouth of pipe of water inlet-outlet segment and the effluent pipe mouth; Pump housing top is provided with the water seal motor cabinet, and motor is installed on the water seal motor cabinet.The nozzle flange of present vertical multi-stage centrifugal pump the entry mouth of pipe and effluent pipe mouth common and water inlet-outlet segment are integral structure, and the shortcoming of the mounting structure of this nozzle flange is: one, because the water-in and water-out section is not a solid of rotation usually, it is very loaded down with trivial details to add man-hour; Two, flange size is fixed, and the pipe arrangement diameter can only be according to fixing flange attachment hole diameter configuration; Three, have error like the flange attachment hole at circumferencial direction, then vertical multi-stage centrifugal pump can't be adjusted angle when mounted, and extremely inconvenience is installed.
The model utility content
It is easy to process that the utility model technical problem to be solved provides a kind of water inlet-outlet segment that can make, and can be convenient and the mounting structure of the vertical multi-stage centrifugal pump nozzle flange of pipe arrangement pipeline connection.
For addressing the above problem; The technological scheme that the utility model adopts is: the mounting structure of vertical multi-stage centrifugal pump nozzle flange, comprise the mouth of pipe, and the mouth of pipe is provided with nozzle flange; Described nozzle flange is sleeved on the mouth of pipe; Described mouth of pipe outer wall is provided with exterior bayonet slot, and card has snap ring in the exterior bayonet slot, described snap ring protrusion exterior bayonet slot; The inwall of described nozzle flange is provided with inner card cage, and described inner card cage blocks the inboard of the snap ring of protrusion exterior bayonet slot part.
The beneficial effect of the utility model: simple in structure, the nozzle flange and the mouth of pipe adopt split type linkage structure, have simplified the processing technology of water inlet-outlet segment greatly; Nozzle flange can be at any rotation angle of circumferencial direction, and the nozzle flange in same holes distance and aperture can be installed on the mouth of pipe arbitrarily, greatly facilitates the installation of vertical multi-stage centrifugal pump and external pipe.
Description of drawings
Fig. 1 is the schematic representation of the mounting structure of the described vertical multi-stage centrifugal pump nozzle flange of the utility model.
Fig. 2 is an A-A sectional structure schematic representation among Fig. 1.
Fig. 3 is a B part structure for amplifying schematic representation among Fig. 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify.
Like Fig. 1, Fig. 2, shown in Figure 3; The mounting structure of vertical multi-stage centrifugal pump nozzle flange comprises the mouth of pipe 1, and the mouth of pipe 1 is provided with nozzle flange 2; Described nozzle flange 2 is sleeved on the mouth of pipe 1; The described mouth of pipe 1 outer wall is provided with exterior bayonet slot 3, and card has snap ring 4 in the exterior bayonet slot 3, described snap ring 4 protrusion exterior bayonet slots 3; The inwall of described nozzle flange 2 is provided with inner card cage 5, and described inner card cage 5 blocks the inboard of the snap ring 4 of protrusion exterior bayonet slot 3 parts.
When with external pipe arrangement pipeline connection, can rotate nozzle flange 2 arbitrarily at circumferencial direction, make the attachment hole on the nozzle flange 2 aim at the attachment hole on the connecting tube, avoided causing the shortcoming that is difficult to connect because of error; The nozzle flange 2 of same apertures can be installed on the mouth of pipe 1 arbitrarily, can select the nozzle flange 2 in corresponding aperture according to the diameter of connecting tube.When needs are pulled down nozzle flange 2, the right direction of nozzle flange 2 in Fig. 2 advanced, pull down snap ring 4 then, be pulled outwardly nozzle flange 2 again and just can nozzle flange 2 be pulled down; When needs are installed nozzle flange 2, required nozzle flange 2 is packed into the inboard of the mouth of pipe 1, then snap ring 4 is snapped in the exterior bayonet slot 3, be pulled outwardly nozzle flange 2 again, make inner card cage 5 in the nozzle flange 2 block snap ring 4 and get final product.Install, dismantle all very convenient.
