Description

Technical Field

[0001] The utility model relates to the field of valve equipment, in particular to an exhaust valve testing device. Background Art

[0002] In terms of heating, among the many reasons that cause poor heating effects for users, air blockage accounts for more than 52%, becoming the primary negative factor affecting the heating effect. The exhaust valve is the only exhaust component of the heating system, and it is also the focus and weak point of the heating system.

[0003] The exhaust valve is mainly used to discharge excess gas in the pipeline system to ensure the smooth operation of the pipeline system. When the internal pressure of the pipeline exceeds the set value, the exhaust valve will automatically open to release the internal overpressure gas or liquid to restore the system pressure to balance. Conversely, when the system pressure drops below the set value, the exhaust valve will close to prevent the gas or liquid from continuing to flow into the exhaust pipe. However, in the actual application of the exhaust valve, the internal structure cannot be directly seen, resulting in no air in the system or exhaust in the system. The external performance of the exhaust valve is the same, and it does not move. Therefore, it is difficult to judge the exhaust performance. Utility Model Content

[0004] To this end, the utility model provides an exhaust valve test device to overcome the problem in the prior art that the exhaust valve performance cannot be quickly confirmed at a construction site.

[0005] To achieve the above object, the utility model provides an exhaust valve test device, comprising:

[0012] Furthermore, a drainage pipe for draining water is provided on the first pressurized pipe, wherein a sixth valve is provided on the drainage pipe.

[0013] Furthermore, a cross-sectional area ratio of a cross section of the transparent pipe to a cross section of the first pressurized pipe, and a cross-sectional area ratio of a cross section of the transparent pipe to a cross section of the second pressurized pipe are both greater than 4.

[0014] Furthermore, the transparent pipe is made of glass or plastic.

The water pressure loading part can simulate the water pressure environment in the actual operation of the HVAC pipe, and the air pressure loading part provides an air blockage simulation in an underwater environment, so that the exhaust performance of the exhaust valve can be directly observed from the transparent pipe. The device has a compact structure and a small size, and only a small amount of water in the water tank is needed to detect the exhaust valve at the construction site.

[0019] Furthermore, the utility model can simulate the performance of exhaust valves under different pressures, thereby being able to test the performance of various types of exhaust valves.

[0020] Furthermore, the utility model provides a pressure-stabilizing tank on the first pressurized pipeline to ensure the water pressure inside the rigid pipeline during the test, and also provides an automatic pressure relief valve on the water pressure monitoring pipeline to prevent the transparent pipeline from rupturing due to excessive internal water pressure.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0027] See also Figure 1 The utility model discloses an exhaust valve test device, comprising:

[0028] A water pressure loading part, which is used to simulate the pipeline water pressure environment, includes a water tank 11, a pressure pump 12 arranged at the output end of the water tank 11 for pumping and pressurizing water, a first valve 13 arranged at the output end of the pressure pump 12, and a first pressurized pipeline 14 arranged at the output end of the first valve 13;

[0029] The air pressure loading part is used to simulate the air blocking environment of the pipeline, including an air pump 21, a second valve 22 arranged at the output end of the air pump 21, and a second pressurized pipeline 23 arranged at the output end of the second valve 22, wherein a check valve 24 is arranged on the second pressurized pipeline 23. It can be understood that the check valve 24 can prevent water from overflowing, thereby realizing a one-way input of gas;

[0030] The observation part is used to observe the test phenomenon of exhaust valve exhaust, including a transparent pipe 31, the bottom end of the transparent pipe 31 is connected to the first pressurized pipe 14, the bottom of the side wall of the transparent pipe 31 is connected to the second pressurized pipe 23, and the top of the transparent pipe 31 is provided with an exhaust pipe 32, and the end of the exhaust pipe 32 is provided with an exhaust valve mounting seat 33, wherein a third valve 34 is provided on the exhaust pipe 32 between the exhaust valve mounting seat 33 and the transparent pipe 31.

[0031] Specifically, the exhaust valve test device also includes a water pressure monitoring unit, which is used to monitor the water pressure in the first pressurized pipe 14, including a water pressure monitoring pipe 41 connected to the first pressurized pipe 14, and a pressure gauge 42 arranged at the end of the water pressure monitoring pipe 41, wherein a fourth valve 43 is arranged between the water pressure monitoring pipe 41 and the pressure gauge 42, and the pressure gauge 42 is used to monitor the water pressure in the first pressurized pipe 14, and the water pressure in the pressurized pipe is usually set to 5 bar.

[0032] Specifically, an automatic pressure relief valve 44 is provided between the fourth valve 43 and the pressure gauge 42. The automatic pressure relief valve 44 is used to automatically relieve internal pressure when the internal water pressure exceeds a certain threshold. For example, the threshold is set to 5.5 bar, thereby effectively protecting the transparent pipe 31 of the device.

[0033] Specifically, the exhaust valve test device also includes a pressure stabilizing part, which is used to stabilize the water pressure in the first pressurized pipe 14, including a pressure stabilizing pipe 51 connected to the first pressurized pipe 14, and a pressure stabilizing tank 52 arranged at the end of the pressure stabilizing pipe 51, wherein a fifth valve 53 is arranged between the pressure stabilizing pipe 51 and the pressure stabilizing tank. It can be understood that the water pressure inside the rigid pipe is sensitive to changes, and the pressure stabilizing tank 52 can increase the elastic fluctuation range of the water pressure inside the test device, thereby effectively ensuring the stability of the pressure inside the device.

[0034] Specifically, the first pressurized pipe 14 is provided with a drain pipe 15 for draining water, wherein the drain pipe 15 is provided with a sixth valve 16. It can be understood that the water inside the device can be quickly drained by opening the sixth valve.

[0035] Specifically, the cross-sectional area ratio of the cross-section of the transparent pipe 31 to the cross-section of the first pressurized pipe 14 is greater than 4, and the cross-sectional area ratio of the cross-section of the transparent pipe 31 to the cross-section of the second pressurized pipe 23 is greater than 4. The larger area ratio can better observe the test phenomenon.

[0036] Specifically, the material of the transparent pipe 31 is glass or plastic, such as acrylic, and is not specifically limited. It only needs to be transparent and colorless so that the internal test state can be observed.

[0037] Specifically, the booster pump 12 is a manual water pressure pump, which can be used for manual water pressure at the construction site and has lower cost than an electric water pressure pump.

[0038] It also includes a fixing part for fixing each pipe, including a first mounting seat 611 and a second mounting seat 612 respectively connected to the first pressurized pipe 14 at one end, a third mounting seat 613 connected to the transparent pipe 31 at one end, and a fixing plate 62 respectively connected to the other ends of the first mounting seat 611, the second mounting seat 612 and the third mounting seat 613. It can be understood that the three mounting seats can firmly fix the test device on the fixing plate 62, so as to facilitate the intuitive display of the test phenomenon.

[0039] Specifically, fixed bases 63 are respectively disposed on both sides of the bottom end of the fixed plate 62 .

[0040] When in use, first, install the exhaust valve to be tested on the exhaust valve mounting seat 33; then, open the first valve 13, the fifth valve 53, the fourth valve 43 and the third valve 34 respectively, and close the sixth valve 16; then use the pressure pump 12 to pressurize the inside of the first pressurized pipe 14 until the pressure gauge 42 shows 5 bar and then close the first valve 13. At this time, the inside of the transparent pipe 31 is full of water and the internal pressure is maintained at 5 bar; then, turn on the air pump 21 and open the second valve 22, and inflate the inside of the transparent pipe 31 through the second pressurized pipe 23; if, the inside of the transparent pipe 31 shows bubbles floating up and boiling, it is determined that the exhaust valve is exhausting smoothly and has good performance. If, the upper interface of the water inside the transparent pipe 31 suddenly drops, it is determined that the exhaust valve is blocked.

[0041] After use, turn off the air pump 21, open the sixth valve 16, drain the water inside the exhaust valve test device, and remove the exhaust valve.

[0042] For those skilled in the art, according to the concept of the embodiments of the utility model, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
