Description
Technical Field
The utility model belongs to the technical field of fluid control, concretely relates to ball-cock assembly.
Background
The existing common ball float valve is composed of a crank arm, a floating ball and other parts, and can be used for automatically controlling the water inlet of a water tower or a water tank so as to control the liquid level.
The working principle of the float valve is as follows: the floating ball always floats on the liquid level, and when the liquid level rises, the floating ball also rises. The floating ball ascends to drive the connecting rod to ascend. The connecting rod is connected with the valve at the other end, and when the connecting rod rises to a certain position, the connecting rod supports the rubber piston pad to seal a water source. When the water level descends, the floating ball also descends along with the liquid level, and the connecting rod drives the piston pad to open the water source. When the pressure of the water inlet source is higher, the floating ball rises to drive the connecting rod to drive the piston pad to close the water inlet source. Because the water inlet pressure borne by the piston is axial force, enough driving force is needed under the condition, the driving force can only increase buoyancy by increasing the volume of the floating ball, and the piston driven by the connecting rod obtains enough acting force to close water inlet. Or under the condition that the volume of the floating ball is not changed, the length of the connecting rod is increased, and the piston is driven to close water inlet by increasing torque. However, no matter the volume of the floating ball is increased or the length of the connecting rod is increased, the use occasion of the floating ball valve is limited by space, and the floating ball valve for arranging the large-volume floating ball and the long connecting rod cannot provide enough space, so that only a liquid level control mode with higher cost can be used.
Disclosure of Invention
In order to solve the problem that exists not enough among the above-mentioned prior art, the utility model aims to provide a float valve, this float valve have simple structure, liquid get into the pressure of float valve no matter the size, do not need to change connecting rod length or floater volume just can normally realize opening or the characteristics of closing of valve.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
a float valve comprises a valve outer cylinder 01 with a liquid inlet, a valve cover 02 and a valve seat 16 which are arranged at the upper end and the lower end of the valve outer cylinder 01, a screw 03 for tensioning the valve cover 02 and the valve seat 16, a valve inner cylinder 13 arranged in the valve outer cylinder 01, a valve core 04 which is arranged in the valve inner cylinder 13 and connected with a connecting rod 06 and can slide up and down in the valve inner cylinder 13 along with the driving of the connecting rod, a floating ball 07 fixed at the tail end of the connecting rod 06 through a nut 08, a movable hinge 09 arranged on the connecting rod 06, a fixed hinge 10 arranged on the valve cover 02, and three pin shafts 05 respectively connecting the valve core 04 and the connecting rod 06, the movable hinge 09 and the connecting rod 06, and the movable hinge 09 and the.
An upper valve outer sealing gasket 11 is arranged between the valve outer cylinder 01 and the valve cover 02, and an upper valve inner sealing gasket 12 is arranged between the valve inner cylinder 13 and the valve cover 02; a lower valve outer sealing gasket 14 is arranged between the valve outer cylinder 01 and the valve seat 16, and a lower valve inner sealing gasket 15 is arranged between the valve inner cylinder 13 and the valve seat 16; an inner sealing ring 17 for sliding sealing is arranged between the valve core 04 and the valve inner cylinder 13.
The valve outer cylinder 01 is a cylindrical cylinder with a liquid inlet.
The valve inner cylinder 13 is a cylinder, a plurality of holes are formed in the side face of the lower end of the cylinder, and the number and the size of the holes are adjustable.
The bottom of the valve seat 16 is a cylindrical cylinder with a liquid outlet pipe orifice, after liquid enters from the pipe orifice of the valve outer cylinder 01, when the valve core 04 is at a high position, the side hole at the lower end of the valve inner cylinder 13 is in an open state, and after the liquid enters the valve inner cylinder 13, the liquid flows out from the pipe orifice at the lower end of the valve seat 16.
In the ball float valve, after liquid enters the interior of the ball float valve through the outer valve cylinder 01, because the ball float 07 is in a low position state at the moment, and the valve core 04 is in a high position state through the connection of the pin shaft 05 by the connecting rod 06, the hole on the side surface of the lower end of the inner valve cylinder 13 is in an open state, and the liquid flows through the inner valve cylinder 13 and then flows out of the pipe orifice of the cylinder at the lower end of the valve seat 16 to enter a container. When the liquid level in the container rises, the floating ball 07 also rises, the valve core 04 is driven by the connecting rod 06 to slide down to a low position state, the valve inner cylinder 13 is in a closed state, and the liquid stops flowing and enters. The sealing gaskets between the valve inner cylinder 13 and the valve outer cylinder 01 and the valve cover 02 and the valve seat 16 are fastened and fixed through the screw 03, and leakage is prevented. Two sealing rings 17 are arranged on the valve core 04, so that the valve is closed more tightly when the valve core 04 is at a low position.
Compared with the prior art, the utility model has the advantages of it is following:
1) the utility model relates to a float valve has valve urceolus 01, and liquid flows in from this, and liquid flows in, leans on axial jacking force effect to jack up the case from case department axial in other float valves. Liquid flows into and gets into behind the valve inner tube 13 from the valve outer tube 01, because the utility model discloses well valve inner tube 13 side trompil, valve core are gliding state from top to bottom, so lead to opening between case and the valve inner tube or close to be the shearing action, the case no longer influences the size of the power that the case produced when flowing by the liquid axial among the prior art, therefore no matter how its pressure size of liquid that gets into the ball-cock assembly, this ball-cock assembly all is suitable for.
2) The utility model discloses in, because the effort optimization of opening or closing by the oil stream axial among the prior art of case and valve inner tube for shearing the effort, no matter get into its pressure size of liquid of ball float valve, this ball float valve is all suitable for, so only need satisfy the frictional force and self gravity that the case activity from top to bottom can be overcome to the selection of floater size and connecting rod length to the drive power of floater luffing motion.
