Description

Technical Field

[0001] The utility model relates to the technical field of flushing device tests, in particular to a service life testing machine for a flushing device. Background Technique

[0002] A water hammer testing machine for a flushing device, as the name implies, is a special equipment for testing the strength and durability of components such as pipelines, valves, and pumps by simulating the transient pressure change (i.e., water hammer phenomenon) generated when the water flow suddenly stops or changes direction in the pipeline system.

[0003] For example, a service life testing machine for a pressure flushing device for a toilet with the application number CN201620684243.6 includes a three-way hydraulic circuit system, a cylinder control single / double gear button testing component, a non-contact distance control error component, and a motor twisting wrench control component; among them, the three-way hydraulic circuit system includes a water tank, a normal temperature water supply tank, a main pipeline, and three branch pipelines. A DN25 ball valve and a G1 hose socket are provided on the normal temperature water supply tank. A DN25 Y-type filter, an external G1-1 / 4 to internal G1 bushing, a water pump mounting plate, a water pump, a motor, a G1*150 external thread pipe, a pressure stabilizing tank, a G1 elbow, a G1 stud, branch pipeline A, a G1 internal thread tee, a G1*100 external thread pipe, branch pipeline B, an external G1 to internal G1 / 2 bushing, branch pipeline C, and a pressure sensor are successively arranged on the main pipeline. This testing machine can complete the service life performance tests of various products such as contact single / double gear pressure flushing devices, mechanical pressure flushing valves, and non-contact pressure flushing valves. The operation is flexible, and the integration level of the equipment is greatly improved. However, when the cylinder presses multiple times through the cylinder, the cylinder may be severely worn due to uneven force and unstable pressing, which seriously affects the service life of the cylinder. Moreover, replacing different flushing devices is cumbersome and the working efficiency is slow.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a service life testing machine for a flushing device is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a service life testing machine for a flushing device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A service life testing machine for a flushing device includes a water accumulation tank and a flushing device. The flushing device is arranged inside the water accumulation tank, and a cylinder is arranged directly above the flushing device. A balance mechanism is fixedly connected to the bottom of the cylinder, and a mounting mechanism is arranged inside the water accumulation tank.

[0007] Preferably, the balance mechanism includes a connecting plate fixedly connected to the bottom of the cylinder. A spring balance rod is fixedly connected to the bottom of the connecting plate, and a pressing block is fixedly connected to the bottom of the spring balance rod.

[0008] Preferably, the installation mechanism includes a mounting hole on the inner surface of the bottom plate of the water storage tank, and a sealing ring is fixedly connected to the inner wall of the mounting hole, and a clamping block is fixedly connected to the top of the water storage tank bottom plate.

[0009] Preferably, an anti-corrosion coating is attached to the outer surface of the cylinder, and a fixing block is fixedly connected to the bottom of the cylinder.

[0010] Preferably, a slider is fixedly connected to one side of the fixing block, and a slide rail is slidably connected to one side of the slider.

[0011] Preferably, a pressure detector is fixedly connected to one side of the pressing block, and a support plate is fixedly connected to one side of the pressure detector, and an operation box is fixedly connected to one side of the support plate.

[0012] Preferably, a water supply tank is arranged on one side of the water storage tank, a delivery pipe is fixedly connected to one side of the water supply tank, and a connecting pipe is arranged between each group of water storage tanks.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the setting of the balance mechanism and the installation mechanism, during the pressing process, the balance mechanism can avoid the problem that the friction between the piston and the cylinder wall increases due to the instability of the contact surface between the cylinder and the contact surface, accelerating the wear of the cylinder, thereby prolonging the service life of the cylinder, making the pressing force applied to the flusher more uniform, improving the accuracy of the test detection results, the installation mechanism is convenient for disassembling and installing the flusher inside the water storage tank, when testing different flushers, it is not necessary to replace the entire water storage tank and the flusher, reducing the operation steps of the staff, while accelerating the test detection efficiency and improving the sealing performance inside the water storage tank;

[0015] 2. Through the setting of the anti-corrosion coating slider, when the cylinder presses the flusher, it is possible that the surface of the cylinder may come into contact with the liquid, and the anti-corrosion coating prevents the surface of the cylinder from being corroded and affecting normal operation. When facing different flushers, the slider drives the pressing block at the bottom of the cylinder to move directly above the flusher, ensuring the accuracy during pressing.

[0016] 3. Through the setting of the water supply tank and the connecting pipe, a water pump is arranged inside the water supply tank, and automated water supply replaces traditional manual water addition. In traditional testing machines, it is necessary to manually pour water into the water supply tank, which is cumbersome to operate and there will be liquid splashing. The connecting pipe penetrates each group of water storage tanks, and water can be automatically delivered to each group of water storage tanks at one time. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 - Figure 2 shown, a life test machine for a flushing device includes a water accumulation tank 1 and a flusher 2. The flusher 2 is arranged inside the water accumulation tank 1, and a cylinder 3 is arranged directly above the flusher 2. The bottom of the cylinder 3 is fixedly connected with a balance mechanism 4, and an installation mechanism 5 is arranged inside the water accumulation tank 1. Different flushers 2 are connected to the water accumulation tank 1 through the installation mechanism 5. The cylinder 3 is located directly above the button of the flusher 2. The balance mechanism 4 improves the stability when the cylinder 3 presses and plays a role in protecting the cylinder.

[0024] As Figure 3 shown, the balance mechanism 4 includes a connecting plate 401 fixedly connected to the bottom position of the cylinder 3, and a spring balance rod 402 is fixedly connected to the bottom of the connecting plate 401. A pressing block 403 is fixedly connected to the bottom of the spring balance rod 402. Multiple groups of spring balance rods 402 are arranged at the bottom of the connecting plate 401, and the distance between each group of spring balance rods 402 is the same. The size of the pressing block 403 is smaller than the button of the flusher 2. A protective layer is arranged at the bottom of the pressing block 403, and pressing the button multiple times will not damage the button.

[0025] Furthermore, the installation mechanism 5 includes an installation hole 501 on the inner surface of the bottom plate of the water storage tank 1. The inner wall of the installation hole 501 is fixedly connected with a sealing ring 502. The top of the bottom plate of the water storage tank 1 is fixedly connected with a clamping block 503. The sealing ring 502 makes the contact between the flusher 2 and the inner wall of the installation hole 501 closer, avoiding water leakage. The clamping block 503 fixes the flusher 2.

[0026] Furthermore, an anti-corrosion coating 6 is attached to the outer surface of the cylinder 3. The bottom of the cylinder 3 is fixedly connected with a fixing block 7. One side of the fixing block 7 is fixedly connected with a sliding block 8. One side of the sliding block 8 is slidably connected with a slide rail 9. The anti-corrosion coating 6 is a polyurethane coating, which has excellent flexibility, wear resistance, oil resistance, high fullness, aging resistance and film-forming performance. The sliding block 8 slides outside the slide rail 9, driving the cylinder 3 to align with the button of the flusher 2, improving the accuracy of pressing.

[0027] Furthermore, a pressure detector 10 is fixedly connected to one side of the pressing block 403. One side of the pressure detector 10 is fixedly connected with a support plate 11. One side of the support plate 11 is fixedly connected with an operation box 12. The pressing effect of the flusher 2 under different pressing forces can be detected by the pressure detector 10.

[0028] Furthermore, a water supply tank 13 is arranged on one side of the water storage tank 1. One side of the water supply tank 13 is fixedly connected with a delivery pipe 14. A connecting pipe 15 is arranged between each group of water storage tanks 1. The delivery pipe 14 can deliver the water source of the water storage tank 1. The connecting pipe 15 connects each group of water supply tanks 1, and a valve is arranged at the connection. By turning on the water pump inside the water supply tank 13, the water source can be delivered to each group of water storage tanks 1.

[0029] Working principle: When using this life tester for the flushing device, first, the flusher 2 is contacted with the installation hole 501 of the installation mechanism 5, and the flusher 2 is connected with the water storage tank 1 through the clamping block 503. Then, turn on the water pump inside the water supply tank 13, and deliver the water source to the inside of the water storage tank 1 through the delivery pipe 14. Turn on the valve outside the connecting pipe 15 to make the appropriate amount of water stored in each group of water storage tanks 1. Then, move the sliding block 8 outside the slide rail 9 to make the center line of the cylinder 3 inside the fixing block 7 coincide with that of the flusher 2. Start the cylinder 3 to drive the pressing block 403 of the balance mechanism 4 to press the flusher 2. During the pressing process, the spring balance rod 402 at the bottom of the connecting plate 401 improves the pressing stability of the cylinder 3. Finally, check the pressure received by the flusher 2 through the pressure detector 10, and view the test result of the flusher 2 through the operation box 12. This is the working principle of this life tester for the flushing device.
