[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0024] As Figures 1-8 shown, a quick installation base for a flue check valve of the present invention includes a check valve base body 1, and further includes an installation mechanism for installing the check valve base body 1 on a flue 4; a groove 14 is provided on one side of the check valve base body 1 in contact with the flue 4, and a sealing ring 15 is provided in the groove 14.

[0025] The installation mechanism includes an installation component 2 and a fixed steel bar 3. Mounting seats 5 are provided on the check valve base body 1, and two groups of mounting seats 5 are symmetrically provided. Two groups of installation components 2 are provided, and the two groups of installation components 2 are respectively arranged on the two groups of mounting seats 5. The fixed steel bar 3 is arranged on the installation component 2. The installation component 2 includes a nut sleeve 6, a threaded rod 7 and a connecting ball 8. An installation hole 9 is provided on the mounting seat 5. The nut sleeve 6 is rotatably arranged in the installation hole 9. An anti-slip knob 11 is sleeved on the nut sleeve 6. The threaded rod 7 is threadedly connected in the nut sleeve 6. The connecting ball 8 is arranged on the threaded rod 7. A perforation 10 is provided on the connecting ball 8. The fixed steel bar 3 is inserted into the perforation 10. The two ends of the fixed steel bar 3 are flat and provided with anti-slip pads 12, and an anti-slip sleeve 13 is provided in the perforation 10.

[0026] During specific use, first place the fixing steel bar 3 into the flue 4 through the smoke holes on the flue 4. Then, press the check valve base body 1 against the wall of the flue 4 according to the specified installation direction of the check valve base body 1. Then, pass the fixing steel bar 3 through the perforations 10 on the two groups of connecting balls 8 respectively. By setting the anti-slip sleeve 13 in the perforations 10, the friction between the perforations 10 and the fixing steel bar 3 can be increased, preventing the fixing steel bar 3 from slipping out of the perforations 10. During the process of inserting the fixing steel bar 3 into the perforations 10, attention should be paid to the direction of the fixing steel bar 3 so that the side of the fixing steel bar 3 with the anti-slip pads 12 at both ends faces the wall of the flue 4 with the smoke holes. After inserting the fixing steel bar 3, rotate the anti-slip knob 11. The anti-slip knob 11 drives the nut sleeve 6 to rotate, the nut sleeve 6 drives the threaded rod 7 and the connecting ball 8 to move, and the connecting ball 8 drives the fixing steel bar 3 to approach the flue 4, making both ends of the fixing steel bar 3 tightly adhere to the wall of the flue 4 with the smoke holes. When both the check valve base body 1 and the fixing steel bar 3 are tightly adhered to the wall of the flue 4, stop rotating the anti-slip knob 11. At this time, the preliminary installation of the check valve base body 1 can be achieved. By setting the anti-slip pads 12 at both ends of the fixing steel bar 3, the friction between the wall of the flue 4 and the fixing steel bar 3 can be increased. By setting the sealing ring 15, the sealing effect between the flue 4 and the check valve base body 1 can be enhanced. After the preliminary installation is completed, sealant can be applied between the check valve base body 1 and the flue 4 according to actual needs to perform secondary reinforcement on the check valve base body 1, and at the same time, the sealing performance between the check valve base body 1 and the flue 4 can be further improved.

[0027] When the check valve base body 1 needs to be disassembled, if there is sealant, first remove the sealant. Then, drive the fixing steel bar 3 away from the wall of the flue 4 by rotating the anti-slip knob 11. Then, draw out the fixing steel bar 3 from the perforations 10, and the check valve base body 1 can be removed for cleaning. The operation is simpler.

[0028] In summary, this solution makes it more convenient to quickly install the check valve base body 1 through the installation mechanism, the operation is simpler and more convenient, and it is also convenient to disassemble the check valve base body 1 according to actual needs, with higher flexibility in use; this solution is provided with a sealing ring 15, and the sealing effect between the flue 4 and the check valve base body 1 can be enhanced through the sealing ring 15.
