Description

Pool pump-changing valve and water drawing system with same
Technical Field
The invention relates to a pool pump-type valve and a water drawing system with the same.
Background
Fire extinguishing equipment is one of necessary facilities for public places or buildings such as buildings, factories, schools, stations, hospitals, etc., fire regulations further stipulate buildings for various purposes, and it is necessary to install various kinds of automatic fire extinguishing equipment when the floor area of the buildings exceeds a certain area. The automatic fire extinguishing equipment is mainly the fire extinguishing equipment of a water system, and occupies more than nine times; contain indoor fire hydrant fire extinguishing apparatus, outdoor fire hydrant fire extinguishing apparatus, automatic water spraying fire extinguishing apparatus, water smoke automatic fire extinguishing apparatus, foam automatic fire extinguishing apparatus to can put out a fire at the very first time that the conflagration took place and handle, or at least can control the intensity of a fire and avoid stretching before fire fighter reachs. In the conventional fire-fighting system using water as fire-fighting, not only enough water source capacity (detailed in fig. 1-2) is required, but also an automatic pressurizing unit (detailed in fig. 1-2) of a fire-fighting pump is required to be installed to ensure sufficient pressure for fire-fighting when the system in the pipe is operated. When a building is normally provided with fire extinguishing equipment of a water supply system; in order to increase the usable area on the one hand and to take into account that the center of gravity of the building is lowered more stably on the other hand, a structure as shown in fig. 1 is mostly selected, and a fire pool 2 is disposed under the bottom floor or ground 1 of the building.
Since the fire pool 2 is usually installed under the ground, even under an underground parking lot, at the bottom of a building, and the fire pool 2 has a certain depth, if the fire pump 4 is a submersible motor, it is difficult to inspect and maintain, so the fire pump automatic pressurizing unit must be of the above-ground type. If the water source of the fire fighting equipment pool of the fire fighting water system is lower than the automatic pressurizing unit of the fire fighting pump, a descending water suction pipe 7 is needed to suck up the fire fighting water in the fire fighting water pool 2.
When air is in the water suction pipe 7, the fire pump can not pump fire water, so as to maintain the function of filling the water suction pipe 7 with water at any time, so the lowest part of the water suction pipe 7 is provided with a bottom valve 8, and the water in the fire pool flows into the water suction pipe 7 in one way by matching with a supplementary water tank (commonly called as a breathing water tank in the fire fighting industry) of an automatic pressurizing unit of an overground type fire pump, so the water suction pipe 7 is filled with water at any time. The bottom valve 8 is used for allowing water to flow to the water suction pipe 7 only from the fire pool 2 and cannot flow back to the fire pool 2 from the water suction pipe 7, so that the water suction pipe 7 and the fire pipeline are filled with fire fighting water at any time, fire fighting equipment of a fire fighting water system is prevented from being capable of extinguishing fire after water pumping and pressurization, and even the pump 4 is damaged due to idling.
Because the fire-fighting equipment of the fire-fighting water system has long piping and high pressure, and the water hammer action often occurs, the material of the bottom valve for fire fighting must meet the requirements of CNS6445 (withstand pressure 10KG/CM2) and the bottom valve has heavy volume, and the bottom valve is buried in water for a long time, so that the bottom valve is difficult to inspect, and when the maintenance and replacement are needed once the fire fighting occurs, if the water in the fire pool 2 is not pumped to be dry and then enters the maintenance by the maintenance personnel, the water suction pipe 7 and the bottom valve 8 need to be pumped and hung to the ground for replacement, because the weight of the water suction pipe 7 is heavy, the water suction pipe needs to be hung by a hanger, and thus, a lot of manpower must be consumed; in particular, some suction pipes 7 are fixed on the fire pool 2 by cement, and the cement envelope needs to be destroyed in a large amount of time, so that the suction pipes 7 and the bottom valve 8 can be taken out together for maintenance.
Generally, the life of the bottom valve is about 3 to 5 years, but most of the damaged bottom valves are inspected, the external casting body and the body are not damaged, mainly because the bottom valve part 131 in fig. 3 is partially damaged, the whole group of bottom valves needs to be replaced, and the replacement of the fault needs to consume manpower or even delay the maintenance time, so that the maintenance cost is increased under the condition of shortage of engineering maintenance personnel, the fire extinguishing equipment of the whole fire-fighting water system is mostly arranged by adopting the mode of fig. 1, and the whole system is completely disabled under the fault of the bottom valve, so the influence cannot be easily seen.
In addition, similar to the above-mentioned fire-fighting pond system, the cultivation of high-economic value seafood such as nine-hole seafood also needs to draw seawater regularly to perform whole or partial water change so as to maintain the water quality index and plankton concentration in the cultivation pond, in order to prevent harmful bacteria such as red tide from being brought by sea tide or natural enemy such as starfish from invading, general cultivation operators tend to arrange the cultivation pond on the coast of the rock bank rather than in the sea to surround the cultivation pond, however, the water drawing system is necessary to ensure that the water supply is not worryed when the water change comes, but the water drawing system often fails to cause the death of a great amount of cultivated materials or affect the product grade and flavor, and the general failure condition is that the bottom valve extending into the seawater end is blocked by sea weeds, is parasitized by shellfish to leak water or is damaged and rusted by the action of salinity.
Therefore, regular maintenance of the bottom valve and replacement of the components that are about to expire in advance become regular work for the grower, and after the red tide subsides, the grower may also sterilize and clean the water drawing system including the bottom valve to ensure the safety of the culture. However, the maintenance cost is high due to the fact that the bottom valve extends into the sea, and people are inconvenient to go to the sea to do maintenance operation and sometimes need to go out of a professional diver, and in addition, the sea image is not good enough in the period of unstable climate, and even if the professional diver is sent out to do operation, the safety risk still exists.
The same water supply problem exists in non-periodically living residential buildings such as private vacation villas, because the private vacation villas are often located in remote areas without tap water supply, a water drawing system is generally adopted to draw well water or spring water for the vacation living, because the private vacation villas are not periodically living, once the water drawing system fails, the embarrassment that no water is available during the vacation period is caused, and the quality of the vacation is greatly influenced. In most fault situations, the bottom valve is blocked or rusted and solidified for a long time, and the bottom valve is difficult to inspect and maintain at ordinary times and difficult to repair and replace during faults.
Therefore, it is a need to improve the conventional replacement of the bottom valve and to provide an inspection function to ensure the smooth operation of the fire fighting system, the aquaculture water supply system and the residential water system.

Detailed Description
The invention is further illustrated with reference to the following figures and specific examples. These examples are to be construed as merely illustrative and not limitative of the remainder of the disclosure in any way whatsoever. After reading the description of the invention, one skilled in the art can make various changes and modifications to the invention, and such equivalent changes and modifications also fall into the scope of the invention defined by the claims.
First preferred embodiment
A first preferred embodiment of a water drawing system with a pool-replaceable valve according to the present invention is shown in fig. 2, in which the water drawing system 10 includes a pump 11, a three-way water drawing component 12, a replaceable valve 13, which is an example of a replaceable bottom valve, and an anti-fouling screen 14, the water drawing system 10 is an example of a water drawing system for a fire fighting system, and the fire fighting system includes a pool 15, which is an example of a fire pool, a water tower 16, a water pipeline 17, which is an example of a water spraying pipeline, and a water using device 18, which is an example of an automatic water spraying device. When the automatic sprinkling device 18 is triggered by the heat sensing of the fire sprinkling head to start continuous sprinkling, the water pipeline 17 and the pressure barrel connected with the water pipeline are gradually reduced in pressure, when the pressure of the pressure barrel is reduced to a pressure switch starting value, the pump control panel starts the pump to operate, the pump 11 pumps and pressurizes the water source in the fire pool 15 upwards through the three-way water suction component 12 and the pumping-changing valve 13 to the water pipeline 17, and the water device 18 continuously pressurizes and extinguishes the fire source.
Referring to fig. 3 and 4, the pump-type valve 13 mainly functions to limit the stored water in the water tank 15 to flow to the pump in one direction, that is, when the pump pumps the stored water in the water tank 15, the bottom valve portion 131 of the pump-type valve 13 is pushed to the water-drawing position by the upward water flow, so that the water can flow to the pump, and once the pump stops drawing the water, the bottom valve portion 131 is pushed to the closed position by the gravity and the downward water flow, so that the water cannot flow back to the water tank 15.
The three-way water sucking assembly 12 includes a three-way body 121, a cover 122 and a water sucking pipe 123, wherein the three-way body 121 has a connecting end 31, a water outlet end 32 leading to the pump, and a replacing end 33 of the through connecting end 31. The replacement end 33 is provided with a sealing cap 122, the removable valve 13 can be taken out for maintenance or repair after the sealing cap 122 is opened, and for easy maintenance or repair, the sealing cap 122 can be made of metal material, or made of transparent material with the same compressive strength, such as CPVC, acrylic, or tempered glass, so that the maintenance personnel can easily observe the inside condition of the tee body 121. In the embodiment, the sealing cover 122 is additionally provided with a manual exhaust valve 35 and a pull handle 36, the manual exhaust valve 35 can exhaust air inside the water suction pipe 123, so as to avoid air remaining in the pipeline to hinder water suction; in daily maintenance, for example, when the breathing tank 9 is installed in a fire fighting automatic pressurization system, the pull handle 36 is lifted up, the bottom valve portion 131 of the replaceable valve 13 is pulled up by the pulling member 134, and it is confirmed whether the water replenishing function of the breathing tank 9 to the water suction pipe is normal, and when the pull handle 36 is lowered down, the bottom valve portion 131 is moved down to the closed position of the base portion 132 by gravity.
The connection end 31 is connected to the suction pipe 123 in a conducting manner, in this embodiment, a straight pipe from the connection end 31 to the replacement end 33 of the tee body 121 is selected to have a predetermined inner diameter with the same size as that of the suction pipe 123, the suction pipe 123 has a suction end 124 opposite to the connection end 31 and sinking into the water pool 15, and the suction end 124 is formed with an inward-contracting shoulder 125 with an inner diameter smaller than the predetermined inner diameter of the suction pipe 123. In this embodiment, the water suction end 124 is further provided with an anti-fouling screen 14, which can prevent impurities in the water tank 15 from flowing into the water suction pipe 123 from the bottom valve portion 131. However, as those skilled in the art can easily understand, even if the inner diameter of the three-way body 121 from the connection end 31 to the replacement end 33 is larger than the predetermined inner diameter, or the connection end 31 to the replacement end 33 is slightly bent, the implementation of the present invention is not hindered as long as the replaceable valve can pass through.
In this embodiment, the connection end 31, the water outlet end 32 and the replacement end 33 are respectively connected to the suction pipe 123, the pump 11 and the cover 122 by a conventional flange (flange) connection method, two ends of the connection are respectively connected to a flange 41, a sealing rubber pad 42 is disposed between the two flanges 41, and the flanges 41 at the two ends are fixedly connected by a screw assembly 43.
Referring to fig. 4 and fig. 5A to 5C, fig. 5A to 5C are schematic views of the lower half of the replaceable valve 13, wherein fig. 5A is a top view, and fig. 5B to 5C are schematic views of the position of the bottom valve portion 131 during operation. The replacement valve 13 includes a bottom valve portion 131, a base portion 132, a stopper portion 133, a pulling member 134, and an access operation member 135, which is illustrated as a fixed member. In this embodiment, the stop portion 133 is circular, and the outer edge of the circular ring is larger than the inward-contracting shoulder 125 and smaller than the predetermined inner diameter of the water suction pipe 123, and is coupled to the deep-entering end 136 of the removable valve 13 through one end of the in-out operation member 135, and the other end is coupled to the cover 122, so that the removable valve 13 is tightly coupled to the inward-contracting shoulder 125, wherein in order to prevent water leakage when the removable valve 13 is coupled to the inward-contracting shoulder 125, a rubber gasket is used as a sealing member (not shown) between the two, and an adjusting screw (not shown) is used at the connection portion between the cover 122 and the in-out operation member 135 to adjust the sealing force when the removable valve 13 is coupled to the inward-contracting shoulder 125. The base part 132 and the bottom valve part 131 are stopped at the stopper 133 by gravity and fixed inside the suction pipe 123, and do not fall from the suction end of the suction pipe 123. The base portion 132 is connected to the stopping portion 133, and the overall profile of the base portion 132 is smaller than the inward-contracting shoulder portion 125, so that when the base portion 132 is stopped by the stopping portion 133, the base portion 132 is exposed from the suction pipe 123. In this embodiment, when the water is not being pumped, the rubber gasket at the bottom of the bottom valve 131 is tightly attached to the base 132 by gravity, so as to ensure that the water in the suction end of the pump 11 and the water suction pipe 123 does not flow back to the pool 15.
In this embodiment, the bottom valve portion 131 is fixed by the base portion 132 along the horizontal direction and can only slide up and down in the gravity direction, so that it can move up and down relative to the base portion 132 and/or the stop portion 133, when the pump 11 pumps water, as shown in fig. 5B, the bottom valve portion 131 is driven by water flow to move up to the water pumping position, so that a space for water circulation is formed between the base portion 132 and the bottom valve portion 131, and the water suction pipe 123 is conducted with the water tank 15, so that the stored water in the water tank 15 as shown in fig. 2 is sucked into the pump 11 through the anti-fouling filter net 14, the bottom valve portion 131, the base portion 132, the water suction pipe 123, the connection end 31 and the water outlet end 32, and then water is supplied to the water using device 18 after being pressurized. When the pump 11 stops pumping water, as shown in fig. 5C, the bottom valve 131 is pushed by gravity and the gravity of water flow in the pipe to move to the closed position, so that water cannot flow between the suction pipe 123 and the water tank 15, and thus the water is opened in one direction, so as to ensure that the suction pipe 123 is filled with water at any time, and avoid the pump 11 from idle rotation and overheating due to the fact that the motor is difficult to pump up water in the pipe because the suction pipe 123 contains air.
When the bottom valve 131 of the replaceable valve 13 is immersed in water in the basin 15 for a long time and is damaged due to a failure, the inserting end 136 of the access operation member 135 is connected to the stopper 133 and/or the base 132 in order to facilitate the removal of the bottom valve 131, and the receiving end 137 opposite to the inserting end 136 is disposed at the replacing end 33, so that the access operation member 135 can be pulled up after the cover 122 is opened, and the bottom valve 131 can be removed along the suction pipe and the tee body for maintenance or repair. In order to make the sealing between the stopping portion 133 and the water suction pipe 123 airtight, an elastic structure such as a spring (not shown) may be additionally provided on the access operation member 135 near the cover 122, so that the stopping portion 133 and the water suction pipe 123 are tightly connected by the elastic force of the elastic structure, thereby preventing the bottom valve portion 131 from moving to the closed position and causing water leakage.
Referring to fig. 3, sometimes, in order to detect whether the pump 11 can start pumping when the water level of the water tower 16 drops below a predetermined level, or when the water suction pipe 123 leaks due to the existence of foreign matter in the bottom valve 131, the bottom valve 131 needs to be manually operated to conduct the water suction pipe 123 with the water pool 15, so that the water in the water tower 16 and the fire fighting pipeline returns to the water pool 15 through the water suction pipe 123 due to the gravity, the water level of the water tower 16 is forced to drop below the predetermined level, and then the pump 11 is triggered to start. In order to manually operate the bottom valve part 131, one end of the pulling member 134 passes through the cover 122 from the inside of the tee body 121, so that the bottom valve part 131 can be controlled to be forcibly opened from the outside of the cover 122, and the other end of the pulling member 134 is connected to the bottom valve part 131 to drive the bottom valve part 131 from the closed position to the water drawing position. The cover 122, the pull handle 36 and the pulling member 134 are airtight and leak-proof, so as to prevent the pump blade from being damaged by air sucked in when the pump 11 sucks water, and the external air can not enter the suction pipe 123 by operating the pull handle 36.
Referring to fig. 2, fig. 3 and fig. 5, or when the examining and repairing staff detects whether the water replenishing function of the breathing tank (replenishing water tank) is normal, the examining and repairing staff can lift the pull handle 36 when the pump is at rest, and pull up the bottom valve 131 of the replacement valve 13 through the testing and repairing pulling member 134 connected thereto, and at this time, the bottom valve 131 is lifted up from the closed water blocking position of fig. 5C to the flowing water position of fig. 5B by manpower, the water in the tee body 121, the suction end of the pump 11 and the breathing tank 9 is higher than the water level of the water tank 15 due to the water level, and the highest water in the breathing tank 9 at each water suction side is stored, and can flow into the water tank 15 through the water suction pipe 123 and the bottom valve 131 by the atmospheric pressure and gravity, and visually confirm whether the water in the breathing tank 9 is normal or not by visually confirming the lowering of the water level, so as to prevent the water leakage phenomena such as the bottom valve 131 not being tightly sealed and not being really adhered, or the water storage hole being rusted in the water suction pipe 123, the breathing tank 9, which is supplied with water constantly, can continuously supply water to the water suction pipe 123, so as to keep the water suction and pressurization functions of the system normal.
