Description

Float valve

Technical Field

The invention relates to the technical field of valves, in particular to a ball float valve.

Background

The existing float valve comprises a valve body with a valve core and a float ball driving part driving the valve core to act, wherein a valve port is arranged on the valve body, water in the valve body can flow out from the valve port and flow into an external water tank, the valve core is positioned at the water outlet end of the valve port, the float ball driving part comprises a float ball and a connecting rod, the float ball is screwed and connected with the connecting rod through a screw, and the connecting rod can drive the valve core to open or close the water outlet end of the valve port. However, in the ball float valve, because the direction of the valve core sealing the valve port is opposite to the flow direction of water flow, the valve core needs to overcome large water flow impact force during sealing, when the water level is close to a set horizontal plane, the water inlet flow is reduced and finally closed, so that the water flow impact impacts the sealing element to obviously influence the service life of the sealing element, and the sealing element is not closed tightly; meanwhile, the drift diameter of the valve port is limited by the buoyancy of the floating ball, so that the valve port must be very small and cannot instantly open or close the water flow channel, and if the floating ball valve is matched with the existing high-flux reverse osmosis water purifier for use, the water purifier cannot be normally shut down.

Disclosure of Invention

The invention overcomes the defects of the prior art and provides the float valve which can instantly open or close the water flow channel, and has the advantages of simple structure, convenient installation, reasonable design and good sealing effect.

In order to achieve the purpose, the invention adopts the technical scheme that: a float valve comprises a valve body, a valve core and a driving component for driving the valve core to act, wherein a valve cavity is arranged in the valve body, a water inlet and a water outlet are arranged on the valve body, the water inlet and the water outlet are respectively communicated with the valve cavity, the driving assembly comprises a floating ball and a driving piece, the floating ball is detachably connected with the driving piece, the valve core is positioned at the water outlet, the valve core is movably arranged in the valve body and can be in sealing fit with the water outlet, a first spring for driving the valve core to move towards the position close to the water outlet is arranged in the valve body, the driving piece is hinged on the valve body, the driving piece is provided with an ejector rod, the ejector rod penetrates through the water outlet, the end part of the ejector rod is abutted against the valve core, the driving piece rotates to drive the ejector rod to move, therefore, the opening of the water outlet is realized by overcoming the elastic force of the first spring and the acting force of the water pressure on the valve core, and a pressure reducing component for reducing the water pressure in the valve cavity is further arranged in the valve cavity.

By adopting the scheme, water flows into the valve cavity from the water inlet and then flows out of the valve cavity to enter the external water tank, the valve core is positioned in the valve body, the valve core is reset under the driving of the first spring, the inner end of the water outlet is sealed, the sealing direction of the valve core is the same as the water flow direction, large water flow impact force does not need to be overcome, the sealing effect is better, when the water level in the water tank reaches the set water level, the floating ball can drive the driving piece to swing in the positive direction, so that the ejector rod is driven to move in the direction away from the valve core, the valve core loses conflict, and the valve core rapidly seals the water outlet under the dual actions of the elastic force of the first spring; when the water level in the water tank is lower than the set water level, the floating ball can drive the driving piece to swing reversely under the action of gravity, thereby driving the mandril to move towards the direction close to the valve core, the acting force of the mandril against the valve core is larger than the elastic force of the first spring and the action of water pressure, the sealing of the valve core to the water outlet is released, the water outlet is opened, of course, if the floating ball is not enough to drive the driving member to overcome the elastic force of the first spring and the water pressure, the driving member can be driven to rotate by the external auxiliary elastic member, thereby increasing the acting force of the mandril against the valve core, the driving piece is detachably connected with the floating ball, the angle of the floating ball is convenient to adjust, the pressure reducing component can be used for disconnecting the water inlet, the water pressure in the valve cavity keeps a constant value, the mandril can jack the valve core more conveniently, thereby switch on the delivery port, add water operation to the water tank, simple structure, simple to operate, reasonable in design.

The invention further provides that: the valve body is provided with a first through hole for the ejector rod to move in the middle of the water outlet, the ejector rod penetrates through the first through hole, one end of the ejector rod abuts against the driving piece, the other end of the ejector rod abuts against the valve core, and the valve body is further provided with a first water passing channel around the first through hole.

Through adopting above-mentioned scheme, the delivery port still is equipped with the first water channel of a plurality of around first through-hole, and the ejector pin when removing in first through-hole can not influence the normal circulation of rivers, and the ejector pin is direct to be contradicted on the driving piece, adopts split type structure, is convenient for process and installation.
