Abstract
The utility model discloses a kind of anti-corrosion centrifugal pump pipe connecting structure, comprise anti-corrosion centrifugal pump, the discharge port of anti-corrosion centrifugal pump is provided with metal winding pipe, metal winding pipe one end is connected with discharge port, the metal winding pipe the other end is connected with one end of an anticorrosion pression hose, anticorrosion pression hose the other end connection metal straight tube, described anticorrosion pression hose inwall is provided with internal thread, anticorrosion pression hose outer wall is provided with outside thread, described anticorrosion pression hose is also arranged with spring outward, and the internal thread of described spring coordinates with the outside thread of anticorrosion pression hose.This anti-corrosion centrifugal pump pipe connecting structure effectively reduces equipment operation stress, avoids damaging the pump housing.
Description
Technical field:
The utility model relates to a kind of centrifugal pump, is specifically a kind of anti-corrosion centrifugal pump pipe connecting structure.
Background technique:
The anti-corrosion centrifugal pump pump housings a lot of in prior art adopts bakelite material to make, and antiseptic property is excellent, but also there is the shortcoming not tolerating extraneous stress.Be connected the stress through often producing because of equipment operation after using a period of time with metallic conduit and cause cracking, causing the pump housing and scrap.
Model utility content:
Technical problem to be solved in the utility model is, provide a kind of anti-corrosion centrifugal pump pipe connecting structure of effective minimizing equipment operation stress, this anti-corrosion centrifugal pump pipe connecting structure can avoid the damage of the bakelite pump housing.
Technical solution of the present utility model is, a kind of anti-corrosion centrifugal pump pipe connecting structure is provided, comprise anti-corrosion centrifugal pump, the discharge port of anti-corrosion centrifugal pump is provided with metal winding pipe, metal winding pipe one end is connected with discharge port, the metal winding pipe the other end is connected with one end of an anticorrosion pression hose, anticorrosion pression hose the other end connection metal straight tube, described anticorrosion pression hose inwall is provided with internal thread, anticorrosion pression hose outer wall is provided with outside thread, described anticorrosion pression hose is also arranged with spring outward, and the internal thread of described spring coordinates with the outside thread of anticorrosion pression hose.
To adopt after above structure compared with prior art; the utility model has the following advantages: by the internal and external threads of anticorrosion pression hose; the stress that equipment produces can be reduced; and the spring be set in outside anticorrosion pression hose can cut down stress further; unlikelyly be transmitted to anti-corrosion centrifugal pump, thus the protection pump housing.
As preferably, between described metal winding pipe and anticorrosion pression hose, between metal straight pipe and anticorrosion pression hose, all pass through Flange joint.Connect effectively simple.
Accompanying drawing illustrates:
Accompanying drawing is structural representation of the present utility model.
Embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in the figure, a kind of anti-corrosion centrifugal pump pipe connecting structure, comprise anti-corrosion centrifugal pump 1, the discharge port 2 of anti-corrosion centrifugal pump 1 is provided with metal winding pipe 3, metal winding pipe 3 one end and discharge port 2 pass through Flange joint, Flange joint is passed through in one end of metal winding pipe 3 the other end and an anticorrosion pression hose 4, anticorrosion pression hose 4 the other end is by Flange joint metal straight pipe 5, described anticorrosion pression hose 4 inwall is provided with internal thread, anticorrosion pression hose 4 outer wall is provided with outside thread, described anticorrosion pression hose 4 is outer is also arranged with spring 6, the internal thread of described spring 6 coordinates with the outside thread of anticorrosion pression hose 4.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.Every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; if interior outer mold cover is square column type structure; ellipsoidal structure, corresponding core also includes within scope of patent protection of the present utility model for square column type structure or ellipsoidal structure etc.
