Description

Technical Field

[0001] The utility model relates to the technical field of air intake and exhaust valves, in particular to an air intake and exhaust valve with a remote alarm function. Background Art

[0002] Suction and exhaust valves are usually used in water supply pipe systems. Their main functions are: first, to smoothly discharge internal air when supplying water from an empty pipe to speed up the water filling process; second, to automatically remove gas generated by various reasons in the pipe to prevent air blockage and pressure fluctuations caused by gas accumulation; third, to inhale air when negative pressure occurs in the pipe to avoid damage such as pipe collapse and rupture due to negative pressure.

[0003] In the northern region, most suction and exhaust valves are installed in special valve wells. Usually, the sanitary conditions in the wells are very poor, and there may even be serious pollution. In the rainy season or when the valve is leaking, there will be a certain degree of water accumulation in the valve well. Once the depth of the accumulated water exceeds the upper suction and exhaust port, and it happens to be in the suction condition, the polluted water will be sucked into the water supply system, causing a water supply safety accident. Even if there is no water suction condition, the water level in the well is higher than the upper suction and exhaust port, which will cause local pollution. The next suction condition or simple water outage will also cause a certain degree of water supply pollution. Therefore, it is necessary to timely detect the excessive water level in the valve well, and promptly find out the situation and take effective measures to avoid the occurrence of water supply safety accidents.

[0004] Existing well water level detection mostly uses general water level detection technology, which is not very targeted. At the same time, due to reasons such as operating technology level, it is difficult to accurately reflect the suction risk. On the other hand, when the automatic exhaust function fails due to the failure of the suction and exhaust valve itself, it will cause pipeline air blockage and pressure fluctuations, which will seriously affect the safe operation of the pipeline. The failure condition should be discovered in time and corresponding measures should be taken. Utility Model Content

[0007] Furthermore, an external alarm float chamber which is open and communicates with the outside is provided on the outside of the valve body, and an external alarm float assembly is provided inside the external alarm float chamber.

[0008] Furthermore, the internal alarm float assembly and the external alarm float assembly are electrically connected to the signal input end of the Internet of Things information processor respectively.

[0010] Furthermore, the valve body controls the closing and opening of the intake and exhaust through a main float that can move up and down in the valve body.

[0011] Furthermore, the main float is located in a float cover in the valve body, and the top and bottom of the float cover are open.

[0012] Furthermore, a lifting cover with a spherical shape protruding upward is fixed above the main float, and the outer edge of the lifting cover corresponds to the annular sealing plate arranged on the valve seat in the valve body.

[0018] like Figure 1-2As shown, a suction and exhaust valve with a remote alarm function includes a valve body 1, and the valve body 1 is a prior art. Specifically, the valve body 1 controls the closing and opening of the suction and exhaust through a main float 7 that can move up and down in the valve body 1. The main float 7 is located in a float cover 8 in the valve body 1. The top and bottom of the float cover 8 are opened. A lifting cover 9 with a spherical shape that protrudes upward is fixed above the main float 7. The outer edge of the lifting cover 9 corresponds to an annular sealing plate 10 set on the valve seat in the valve body 1. The lifting cover 9 is closed after it is tightly attached to the sealing plate 10. The top of the valve body 1 is covered and fixed with a valve cover 11. The valve cover 11 has exhaust ports on the edges of the four sides. A guide rod fixed on the upper end of the main float 7 A guide hole passes through the valve cover 11, and one side of the valve body 1 is connected to an externally sealed internal alarm float chamber 3 through a through hole 2 arranged up and down. The internal alarm float chamber 3 is preferably arranged at the side wall of the valve body 1 on the side of the main float 7. An internal alarm float assembly 4 for detecting the liquid level of the internal alarm float chamber 3 is arranged in the internal alarm float chamber 3. The upper and lower through holes 2 are connected so that when the liquid level in the valve body 1 is between the through holes 2, the liquid level of the internal alarm float chamber 3 is the same as the liquid level height of the valve body 1. Once the liquid level in the valve body 1 drops or drops below the through hole at the bottom, the liquid level in the internal alarm float chamber 3 drops, or is emptied, thereby facilitating the lowering of the internal alarm float of the internal alarm float assembly 4.

[0019] The valve body 1 is also provided with an external alarm float chamber 5 which is open and connected to the outside. The external alarm float chamber 5 is provided on the side of the outer wall of the internal alarm float chamber 3. The external alarm float chamber 5 and the internal alarm float chamber 3 are integrally formed, and the opening of the external alarm float chamber 5 faces downward. The external alarm float assembly 6 is provided inside the external alarm float chamber 5. The internal alarm float assembly 4 and the external alarm float assembly 6 are respectively electrically connected to the signal input end of the Internet of Things information processor 12. The alarm float assembly is a prior art, such as the float liquid level switch produced by Dongguan Chicheng Electronics Co., Ltd., and the Internet of Things information processor 12 is also a prior art, which can realize Internet of Things information processing and data exchange with the cloud data center.

[0020] Working principle of the utility model

[0021] The water level over-limit alarm function in the valve well is realized as follows: during normal operation, when there is no water in the valve well or the water level is low, the external alarm float is in a low position, that is, the internal reed switch of the external alarm float assembly 6 is not energized, the circuit is disconnected, and the Internet of Things information processor 12 is in a dormant state; when the water level in the valve well rises to a certain height, the buoyancy of the water will push the external alarm float of the external alarm float assembly 6 to rise, and when it approaches and reaches its upper limit of travel, the internal reed switch of the external alarm float assembly 6 is energized, and the circuit is in a "connected" state. The Internet of Things information processor 12 is awakened by this connection signal, and a "well water level over-limit alarm" is sent to the remote data center. Combined with the preset geographic information, an alarm message is sent to the administrator's mobile phone for timely processing.

[0022] The automatic exhaust function failure alarm function is implemented as follows: during normal operation, the water level in the valve body 1 is at the normal water level position, the buoyancy of the water will push the internal alarm float of the internal alarm float assembly 4 to the upper limit position, the internal reed switch of the internal alarm float assembly 4 is not energized, the circuit is disconnected, and the Internet of Things information processor 12 is in a dormant state; when the exhaust function fails, air accumulates in the valve body 1, causing the water level to drop. When the water level drops to its lower limit water level or below, the internal alarm float of the internal alarm float assembly 4 falls to close to or reach its lower limit of travel, and the internal reed switch of the internal alarm float assembly 4 is energized and turns to the "on" state. The Internet of Things information processor 12 is awakened by this on signal, and an "automatic exhaust failure alarm" is sent to the remote data center. Combined with the preset geographic information, an alarm message is sent to the administrator's mobile phone for timely processing.

[0023] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
