Description

Technical Field

[0001] This utility model relates to the field of unloading valve technology, and in particular to an unloading valve with a multi-applicable connection structure. Background Technology

[0002] Discharge valves are commonly used in ventilation and dust removal systems, pneumatic conveying systems, and other similar applications to discharge collected materials. In terms of transmission structure, they typically employ a direct-drive geared motor. The end cover of the geared motor is fixed to the mounting base at the power input end of the discharge valve. The geared motor shaft is then connected to the impeller shaft via a coupling, driving the impeller to rotate and thus discharging the material.

[0003] The connecting flanges on the existing unloading valve mounting bases are mostly conventional circular structures, usually consisting of three watermelon-slice-shaped arc plates forming an integral connecting flange. The application range of this circular connecting flange is somewhat limited, and it basically needs to be matched one-to-one with the end cover of the geared motor. If it is necessary to meet the installation of geared motors of multiple specifications, it will result in material waste and increased costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a discharge valve with a versatile and material-saving multi-applicable connection structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a discharge valve with a multi-applicable connection structure, including a valve body, an impeller rotatably disposed in the valve body, and an impeller shaft fixed to the center of the impeller. The upper end of the valve body has a feed flange, and the lower end of the valve body has a discharge flange. The side of the valve body at the power input end of the impeller shaft is provided with a mounting seat. The mounting seat includes a round flange fixed to the valve body and a square flange fixed to the motor end cover of the discharge valve. Rectangular plates are fixed between the left and right sides of the round flange and the square flange, respectively. The square flange has four connection holes distributed in a rectangle and located on the same circumference.

[0006] Specifically, a first bearing housing is installed at the center of the round flange, and a second bearing housing is installed at the center of the square flange. The power end of the impeller shaft is rotatably supported between the first bearing housing and the second bearing housing.

[0007] To improve the support strength of the mounting base, triangular ribs are fixed at both ends of the rectangular plate, and the two ends of the triangular ribs are fixed to the square flange and the round flange, respectively.

[0008] The beneficial effects of this utility model are: This utility model uses a square flange to connect with the end cover of the geared motor, which can meet the installation requirements of various specifications of geared motors by changing the size of the circumference of the four connecting holes. Especially for some geared motors with larger end cover diameters, even if the outer circumference of the geared motor end cover protrudes beyond the four sides of the square flange, the installation requirements can still be met. Moreover, compared with the traditional round flange, the square flange saves more materials and reduces costs. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] like Figures 1-4 The discharge valve shown has a multi-purpose connection structure, including a valve body 1, an impeller 2 rotatably mounted inside the valve body, an impeller shaft 3 fixedly connected to both ends of the center of the impeller 2, a feed flange 4 connected to an external feed pipe at the upper end of the valve body 1, and a discharge flange 5 connected to an external discharge pipe at the lower end of the valve body 1.

[0019] A mounting base 6 is fixed on the front side of the valve body 1 located on the power input end of the impeller shaft 3. The mounting base 6 includes a round flange 7 and a square flange 9. The round flange 7 is fixed to the side of the valve body 1, and the square flange 9 is used to be fixed to the end cover of the unloading valve reducer motor. A rectangular plate 8 is fixed between the left and right sides of the round flange 7 and the square flange 9, respectively. The square flange 9 has four connecting holes 10 that are rectangularly distributed and located on the same circumference.

[0020] The circular flange 7 has a first bearing seat 11 installed at its center, and the square flange 9 has a second bearing seat 12 installed at its center. The power end of the impeller shaft 3 is rotatably supported between the first bearing seat 11 and the second bearing seat 12.

[0021] The rectangular plate 8 has triangular rib plates 13, which are integral with the rectangular plate 8, fixed at both ends. The two ends of the triangular rib plates 13 are fixed to the square flange 9 and the round flange 7, respectively, to improve the support strength of the mounting base 6.

[0022] Similarly, the aforementioned mounting base 6 is also installed on the rear side of the valve body 1 on the non-powered side of the impeller shaft 3 to support the impeller shaft 3 on the non-powered side.

[0023] See Figure 5 , Figure 6 The double-dotted line in the figure represents the end cover of the geared motor. When connected to the end cover of the geared motor through the four connecting holes 10 on the square flange 9, the connection requirements of geared motor end covers of various sizes can be met simply by changing the circumference diameter of the four connecting holes 10. Especially for some geared motors with larger end cover diameters, the installation requirements can still be met even if the outer circumference of the geared motor end cover protrudes beyond the four circumferences of the square flange 9. Moreover, compared with the traditional round flange, the square flange 9 can save materials and reduce costs.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
