The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0028] Example 1

[0029] See also Figures 1 to 6 In this embodiment, a quick-detachable valve cover is provided, including a pump body 1, a lower pump cover 2 is fixedly connected to the upper end of the pump body 1, an upper pump cover 3 is detachably connected to the upper end of the lower pump cover 2, and also includes a valve cover installation component 4 and a leakage alarm component 5. The valve cover installation component 4 is connected with multiple groups between the lower pump cover 2 and the upper pump cover 3, and the leakage alarm component 5 is sleeved on the outer sides of the lower pump cover 2 and the upper pump cover 3.

[0030] like Figure 6 As shown, in order to quickly install and disassemble the lower pump cover 2 and the upper pump cover 3, the valve cover installation assembly 4 provided in the present scheme includes a mounting column 6, which is fixedly connected to the upper end of the lower pump cover 2, and a mounting hole 7 is provided at the upper end of the upper pump cover 3. The upper end of the mounting column 6 passes through the mounting hole 7 and is slidably connected to the upper end of the upper pump cover 3. A receiving hole 8 is provided on one side of the upper end of the mounting column 6, and a limit member 9 is provided in a sliding connection inside the receiving hole 8. A first spring 10 is connected between the limit member 9 and the inner wall of the receiving hole 8, and a slope is provided on the side of the limit member 9 away from the first spring 10, so as to facilitate fixing the upper pump cover 3 on the lower pump cover 2.

[0031] like Figure 5As shown in the figure, in order to improve the safety performance of the equipment, give an alarm in time when a leakage occurs, and remind relevant personnel to carry out maintenance, the leakage alarm component 5 set in this solution includes a rubber sleeve 13, a mobile power supply 21 and an alarm 22. The rubber sleeve 13 is sleeved on the outer sides of the lower pump cover 2 and the upper pump cover 3. An alarm box 14 is connected to the upper end of the upper pump cover 3. An alarm frame 15 is opened inside the alarm box 14. A connecting pipe 16 is communicated between the rubber sleeve 13 and the alarm box 14. A push plate 17 is slidably connected inside the alarm frame 15. A second spring 18 is fixedly connected between the push plate 17 and the inner wall of the alarm frame 15. A first contact 19 is connected to one side of the push plate 17. A second contact 20 is connected to the inner wall of the alarm frame 15. The first contact 19 and the second contact 20 are electrically connected. The mobile power supply 21 and the alarm 22 are connected and arranged at the upper end of the alarm box 14. The first contact 19, the mobile power supply 21, the alarm 22 and the second contact 20 are connected by wires.

[0032] Among them, an upper sealing ring 11 is connected to the upper end of the lower pump cover 2, and a lower sealing ring 12 is connected to the lower end of the upper pump cover 3.

[0033] When using the present utility model, when the staff needs to install the upper pump cover 3 on the lower pump cover 2, align the installation hole 7 on the upper pump cover 3 with the outside of the installation post 6 on the lower pump cover 2, and press down the upper pump cover 3. The lower end of the upper pump cover 3 will squeeze the limiting member 9 into the inside of the receiving hole 8. When the upper pump cover 3 descends below the receiving hole 8, under the action of the first spring 10, the limiting member 9 extends out of the receiving hole 8 to limit the upper part of the upper pump cover 3, realizing the fixation of the upper pump cover 3 and the lower pump cover 2. Then, the rubber sleeve 13 is sleeved on the outer sides of the lower pump cover 2 and the upper pump cover 3 to realize the sealing of the lower pump cover 2 and the upper pump cover 3;

[0034] When a leakage occurs, liquid or gas enters the inside of the rubber sleeve 13 and enters the inside of the alarm box 14 through the connecting pipe 16, pushing the push plate 17 to squeeze the second spring 18, so that the first contact 19 contacts the second contact 20. At this time, the first contact 19, the second contact 20, the mobile power supply 21, and the alarm 22 form a closed loop, and the alarm 22 is powered on to give an alarm, reminding relevant personnel to handle it;

[0035] When it needs to be disassembled, first remove the rubber sleeve 13 from the outer sides of the lower pump cover 2 and the upper pump cover 3, then squeeze the limiting member 9 to make the limiting member 9 enter the inside of the receiving hole 8, and pull the upper pump cover 3 to take out the upper pump cover 3 from the outside of the installation post 6, realizing the disassembly of the lower pump cover 2 and the upper pump cover 3.

[0036] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
