Abstract
The utility model relates to the technical field of water supply and drainage, in particular to a self-determined type negative pressure suppressor. The self-determined type negative pressure suppressor comprises a buffer tank, an air exhaust pipe is arranged on the buffer tank, an air exhaust channel is formed in the middle of the air exhaust pipe, a floating ball is further arranged at the position, located right below the air exhaust channel, inside the buffer tank, a sliding rod is fixedly connected to the floating ball, a sliding rod support is further arranged inside the buffer tank, a sliding rod hole is perpendicularly formed in the sliding rod support, the sliding rod penetrates through the sliding rod hole, when the water level in the buffer tank reaches the normal standard, the floating ball abuts against the air exhaust channel to enable the interior of the buffer tank to be isolated with the air exhaust channel in an airtight mode, and when the water level in the buffer tank is lower than the normal standard, the floating ball descends and the interior of the buffer tank and the air exhaust channel are communicated. The self-determined type negative pressure suppressor can suppress the negative pressure generated by a water supply pipe.
Description
Technical field
The utility model relates to the plumbing technical field, especially a kind of restraining device that can suppress supply channel generation negative pressure.
Background technology
In water system, the water inlet pipe and the flow in outlet pipe that are connected with baffle-box must be consistent, and inhale Cheng Xianxiang if the flow in outlet conduit greater than the flow in inlet channel, can produce negative pressure, affect other users' quality of water supply.In water system work at ordinary times, in order to improve the height of water supply, often booster pump to be set on outlet pipe, during the booster pump startup, the flow in outlet pipe can increase suddenly, makes and produces negative pressure suction Cheng Xianxiang in water inlet pipe.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of from the fixed pattern negative pressure inhibition device, and the negative pressure that can eliminate in water supply line is inhaled Cheng Xianxiang.
in order to solve the problems of the technologies described above, the utility model comprises baffle-box, be provided with stack on baffle-box, be provided with the exhaust passage in the middle of stack, described baffle-box inside be positioned at the exhaust passage under also be provided with ball float, be fixedly connected with slide bar on ball float, described baffle-box inside also is provided with the slide bar bearing, be vertically installed with sliding rod hole on the slide bar bearing, described slide bar passes sliding rod hole, when in baffle-box, water level reaches arm's length standard, described ball float withstands the exhaust passage, make baffle-box inner airtight isolated with the exhaust passage, when the baffle-box water level inside is below the normal, described ball float descends, baffle-box is inner to be connected with the exhaust passage.
Described exhaust passage is provided with sliding cave near the port of baffle-box, and described sliding cave shape and ball float shape are complementary, and are provided with rubber layer on the inwall in described sliding cave.
The free end of described slide bar is fixedly connected with Metal Ball.
When booster pump started, the water level in baffle-box can descend, and ball float descends with water level simultaneously, and baffle-box inside and exhaust passage are connected, and inhaled Cheng Xianxiang thereby can not produce negative pressure.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The embodiment that the utility model is cited; just be used for helping to understand the utility model; should not be construed as the restriction to the utility model protection domain; for those skilled in the art; under the prerequisite that does not break away from the utility model principle and aim; can also improve the utility model, these improve in the scope that also falls into the protection of the utility model claim.
as shown in Figure 1, the utility model comprises baffle-box 1, be provided with stack 2 on baffle-box 1, be provided with exhaust passage 21 in the middle of stack, described baffle-box 1 inside be positioned at exhaust passage 21 under also be provided with ball float 3, be fixedly connected with slide bar 31 on ball float, described baffle-box 1 inside also is provided with slide bar bearing 4, be vertically installed with sliding rod hole on slide bar bearing 4, described slide bar 31 passes sliding rod hole, when in baffle-box, water level reaches arm's length standard, described ball float 3 withstands exhaust passage 21, make baffle-box 1 inner airtight isolated with exhaust passage 21, when baffle-box 1 water level inside is below the normal, described ball float 3 descends, baffle-box 1 is inner to be connected with exhaust passage 21.Described stack 2 also can arrange one and be used for the whether signal pickup assembly 24 of closes vent passage 21 of perception ball float 3, described signal pickup assembly is electrically connected to booster pump 5, booster pump 5 is adjusted operating frequency according to the signal of signal pickup assembly, when cistern water level descends, after signal pickup assembly 24 perceives ball float 3 declines, signal is passed to booster pump, and booster pump can reduce operating power, makes cistern water level recover normal.
In order to improve the airtight performance between ball float 3 and exhaust passage 21, described exhaust passage 21 is provided with sliding cave 22 near the port of baffle-box, and described sliding cave 22 shapes and ball float 3 shapes are complementary, and are provided with rubber layer 23 on the inwall in described sliding cave 22.
Depart from order to make ball float that direction not occur in the process that moves up and down, the free end of described slide bar 31 is fixedly connected with Metal Ball 32.
When booster pump 5 starts, thereby the flow of baffle-box internal drainage pipe 6 descends water level greater than the flow of water inlet pipe 7, and ball float descends with water level simultaneously, baffle-box inner and exhaust passage is connected, thereby can not produce negative pressure suction Cheng Xianxiang.This is that signal picker 24 can be controlled booster pump reduction operating frequency, thereby makes water level progressively recover normal.
