[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0019] The present invention will be further described below with reference to the embodiments.
[0020] Example: Refer to Figures 1 to 3 A sanitary quick-install manual weir-type diaphragm valve includes a diaphragm valve body 1 and a valve cover 11. An annular mounting seat 12 is fixedly connected to the connection point on the upper end face of the diaphragm valve body 1. Multiple quick-installation mechanisms are provided, including a convenient installation component 2, a pressing component 3, and a reinforcing component 4. The convenient installation component 2 includes a through groove 21 opened on the side wall of the annular mounting base 12. An inclined limiting block 22 is slidably connected in the through groove 21. A first guide rod 23 is fixedly connected to the side wall of the annular mounting base 12. A first moving block 24 is slidably sleeved on the first guide rod 23. A first spring 25 is fixedly connected between the first moving block 24 and the side wall of the annular mounting base 12. The two side walls of the inclined limiting block 22 are respectively in contact with the two inner walls of the through groove 21 to ensure the stability of the convenient installation component 2 during operation. The pressing component 3 includes a second guide rod 31 fixedly connected to the upper surface of the first moving block 24, a second moving block 32 slidably sleeved on the second guide rod 31, an inclined limiting block 22 fixedly connected to the side wall of the second moving block 32, a top plate 33 fixedly connected to the top of the second guide rod 31, a second spring 34 fixedly connected between the second moving block 32 and the top plate 33, and a first spring 25 and a second spring 34 respectively sleeved on the first guide rod 23 and the second guide rod 31; The reinforcement component 4 includes a threaded through hole 41 between the upper surface of the annular mounting base 12 and the through groove 21. A threaded rod 42 is threadedly connected to the threaded through hole 41. A pressure plate 43 is fixedly connected to the bottom end of the threaded rod 42. A knob is fixedly connected to the top end of each of the multiple threaded rods 42 for easy use by the staff. Multiple pressure plates 43 are located in multiple through grooves 21 respectively.
[0021] The working principle of this utility model is as follows: When it is necessary to install the valve cover 11 onto the diaphragm valve body 1, the valve cover 11 is placed in the corresponding position of the diaphragm valve body 1, so that the edge of the valve cover 11 corresponds to the annular mounting seat 12. During the placement process, the edge of the valve cover 11 will contact the inclined surface of the inclined limiting block 22 and push the inclined limiting block 22 to slide into the through groove 21. The inclined limiting block 22 drives the second moving block 32 to slide down along the second guide rod 31, and the second spring 34 is stretched. At the same time, the inclined limiting block 22 will also drive the first moving block 24 to move away from the annular mounting seat 12 along the first guide rod 23, and the first spring 25 is stretched. Once the valve cover 11 is in place, under the elastic action of the first spring 25, the first moving block 24 will drive the relevant components to reset, and the inclined limiting block 22 will also pop out from the through groove 21 to limit the valve cover 11. At the same time, under the elastic action of the second spring 34, the second moving block 32 will drive the inclined limiting block 22 to have a tendency to move downward, further enhancing the limiting effect on the valve cover 11, and initially completing the installation of the valve cover 11 and the diaphragm valve body 1. Then, by rotating the knob, the threaded rod 42 moves downward in the threaded through hole 41, which drives the pressure plate 43 to move downward. The pressure plate 43 presses the inclined limiting block 22, making the inclined limiting block 22 contact the valve cover 11 more tightly, achieving a reinforcement effect and ensuring the stability of the connection. When it is necessary to remove the valve cover 11, turn the knob in the opposite direction to make the threaded rod 42 move the pressure plate 43 upward, release the pressure on the inclined limiting block 22, and then pull the relevant parts to release the inclined limiting block 22 from restricting the valve cover 11, so that the valve cover 11 can be removed, which is efficient and convenient.
[0022] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
