Abstract
The utility model relates to the technical field of water supply plants, particularly relates to a sealing device of a negative-pressure-free water supply plant, and is provided with a flow governor which is provided with a sealing plug and a floater. A water inlet and a water outlet are arranged on the flow governor, the sealing plug corresponds to the water outlet, and the floater corresponds to the water inlet. The sealing device is characterized in that a buoyancy force amplifier is arranged between the floater and the sealing plug and composed of a support rod, a lever and an ejection rod, the support rod is fixed on the flow governor, the lever is hinged with the support rod, one end of the lever is connected with the floater, the other end of the lever is connected with the sealing plug through the ejection rod. By means of the lever principle, the floater produces acting force acted on the sealing plug to achieve tens times of the self buoyancy force, sealing acting force is bog, water in the flow governor is not easy to flow out, and the sealing device has the advantages of being simple in structure, big in buoyancy force, high in sealing performance, long in service life, saving in water resources and the like.
Description
Technical field
The utility model relates to the supply equipment technical field, specifically a kind of obturator of non-negative pressure water-supply installation.
Background technology
Non-negative pressure water-supply installation mainly is made up of flow regulator, water pump and pipeline, and the water inlet of flow regulator links to each other with the tap water pipe network, and delivery port is supplied with the resident through water pump, and its purpose causes negative pressure can not for the tap water pipe network except supplying water to the resident.Mostly the obturator of non-negative pressure water-supply installation in the market is to adopt sealing-plug directly to be connected with ball float through connecting rod, and when the liquid level of flow regulator was raised to the ball float position, ball float floated; Promote the sealing device seal fluid, when liquid level descends, lean on the gravity of ball float to break off sealing device; Flow regulator and atmosphere; Be difficult for making tap water pipe line to cause negative pressure, sealing force is to lean on the buoyancy of ball float fully, causes sealing sometimes incessantly; Water in the flow regulator overflows, and poor sealing performance, application life are short, waste water resource.
Summary of the invention
The purpose of the utility model is the deficiency that solves above-mentioned prior art, provide a kind of simple in structure, buoyancy is big, sealing performance is high, the obturator of the non-negative pressure water-supply installation of long service life, conserve water resource.
The utility model solves the technical scheme that its technical problem adopted:
A kind of obturator of non-negative pressure water-supply installation is provided with flow regulator, is provided with sealing-plug and ball float in the flow regulator; Flow regulator is provided with water inlet and delivery port, the corresponding delivery port of sealing-plug, the corresponding water inlet of ball float; It is characterized in that being provided with the buoyancy amplifier between ball float and the sealing-plug, the buoyancy amplifier is made up of pole, lever and push rod, and strut fixation is on flow regulator; Lever and pole are hinged, and lever one end is connected with ball float, and the other end is connected with sealing-plug through push rod; Utilize lever principle; Ball float is produced act on active force on the sealing-plug to reach tens of times of self buoyancy, sealing function power is big, is difficult for making the water in the flow regulator to overflow.
The utility model can be provided with the buoyancy amplifier more than two covers in flow regulator; Join end to end through connecting rod between the lever in the buoyancy amplifier, when liquid level rose, ball float amplified 6 ~ 8 times through the first cover lever with buoyancy; Through connecting rod the active force that amplifies is amplified 5 ~ 6 times through the second cover lever again and pass to sealing-plug; Make sealing-plug produce the sealing force of tens of times of ball float buoyancy, the water in the dependable flow adjuster does not overflow, otherwise; When liquid level descended, the gravity of ball float was through two cover lever transmission and break off sealing.
The utility model is owing to adopt said structure; Solved and depended merely on ball float buoyancy and promote sealing-plug and carry out seal fluid; The defective that when buoyancy is not enough liquid in the flow regulator is overflowed has simple in structure, advantages such as buoyancy is big, sealing performance is high, long service life, conserve water resource.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Reference numeral: sealing-plug 1, pole 2, lever 3, ball float 4, flow regulator 5, push rod 6, connecting rod 7.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Shown in accompanying drawing, a kind of obturator of non-negative pressure water-supply installation is provided with flow regulator 5; Be provided with sealing-plug 1 and ball float 4 in the flow regulator 5, flow regulator 5 is provided with water inlet and delivery port, sealing-plug 1 corresponding delivery port; Ball float 4 corresponding water inlets is characterized in that being provided with the buoyancy amplifier between ball float 4 and the sealing-plug 1, and the buoyancy amplifier is made up of pole 2, lever 3 and push rod 6; Pole 2 is fixed on the flow regulator 5, and lever 3 is hinged with pole 2, and lever 3 one ends are connected with ball float 4; The other end is connected with sealing-plug 1 through push rod 6, utilizes lever principle, makes ball float 4 produce the active force that acts on the sealing-plug 1 and reaches tens of times of self buoyancy; Sealing function power is big, is difficult for making the water in the flow regulator 5 to overflow.
The utility model can be provided with the buoyancy amplifier more than two covers in flow regulator 5, join end to end through connecting rod 7 between the lever 3 in the buoyancy amplifier.
When liquid level rises; Ball float amplifies 6 ~ 8 times through the first cover lever with buoyancy, through connecting rod 7 active force that amplifies is amplified 5 ~ 6 times through the second cover lever again and passes to sealing-plug 1, makes sealing-plug 1 produce the sealing force of tens of times of ball float buoyancy; Water in the dependable flow adjuster 5 does not overflow; Otherwise when liquid level descended, the gravity of ball float 4 transmitted and the disconnection sealing through two cover levers 3.
The utility model is owing to adopt said structure; Solved and depended merely on ball float 4 buoyancy and promote sealing-plug 1 and carry out liquid seal; The defective that when buoyancy is not enough liquid in the flow regulator 5 is overflowed has simple in structure, advantages such as buoyancy is big, sealing performance is high, long service life, conserve water resource.
