Abstract

A rolling gravity spherical valve can rotate the valve body with a certain angle, and filter fluid at the same time by closing or opening a valve with the function of gravity; the valve body is arranged in a fluid vessel 7, the valve body 1 is provided with at least a fluid outlet and opened with a filtering pore 2; the valve body 1 is internally provided with a ball body 4 that can freely roll, and the inner wall of the valve body 1 arranged at the fluid outlet is a taper hole shape; a sealing gasket 5 is closely attached on the taper hole shaped inner wall of the valve body 1 at the fluid outlet, and a fluid discharge pipe 6 is connected with the outside of the valve body, and the diameter of ball body 4 is larger than the taper diameter of the taper hole in the fluid outlet.

Description

Rolling gravitational force ball-valve

Technical field

The present invention relates to a kind of valve mechanism, specifically is the gravitational force ball-valve that utilizes action of gravity

Background technique

The structure technology of relevant weight valve is less at present, and the common trait of existing several weight valves is to connect a spheroid by a valve rod or cord, utilizes the pulling force of spheroid self gravitation or weight, and spheroid is blocked fluid output; Mainly utilize fluid buoyancy or other external force that valve ball is mentioned during valve open, finish the function of valve and so forth, these valves are mainly used in toilet seat water tank.But at the valve that can need a kind of like this function in some cases: be exactly to require when fluid container is in different angles of inclination or rotation angle, valve can close or open automatically; Perhaps in a fluid container two or more fluid outlets are arranged, when requirement is in different angles of inclination or rotation angle at fluid container, the delivery outlet that requirement has is closed automatically, the delivery outlet that has is opened automatically, this class valve does not also produce at present, runs into such problem and is difficult to solve.

Summary of the invention

Of the present inventionly provide a kind of rolling gravitational force ball-valve, can make the valve body rotating certain angle, utilize action of gravity to close or open valve, convection cell filters simultaneously.

Rolling gravitational force ball-valve, be installed in the fluid container 7, has a fluid output on the valve body 1 at least, on valve body 1, have and filter aperture 2, it is characterized in that a spheroid that can arbitrarily roll 4 is arranged in valve body 1, the inwall that is positioned at fluid outlet valve body 1 is the conical bore shape, and the diameter of spheroid 4 is positioned at the cone diameter of fluid outlet greater than this conical bore.

The invention has the beneficial effects as follows: utilize action of gravity, in the valve body rotating certain angle, open as required or throttle down, convection cell plays a role in filtering simultaneously.

Embodiment

As shown in Figure 1a, rolling gravitational force ball-valve, be installed in the fluid container 7, valve body 1 has a fluid output at least, has to filter aperture 2 on valve body 1, and a spheroid that can arbitrarily roll 4 is arranged in valve body 1, the inwall that is positioned at fluid outlet valve body 1 is the conical bore shape, sealing gasket 5 is installed on this conical wall, and external fluid discharge pipe 6, the diameter of spheroid 4 are positioned at the cone diameter of fluid outlet greater than this conical bore.

As shown in Figure 1a, spheroid 4 is positioned at conical sealing gasket 5 when valve body 1 is in upright state, and fluid output is sealed, and valve is in closed condition; Shown in Fig. 1 b, when the inverse position hour hands half-twist of valve body 1 from Fig. 1 a,, roll to another equilibrium position just spheroid 4 leaves sealing gasket 5 positions, this moment valve open, fluid is flowed out by fluid discharge pipe 6.

Shown in Fig. 2 a, valve body 1 is the tri-prism shape, shown in Fig. 2 b, is the internal structure of ball valve, and valve body 1 rotates to the left or to the right, all can make valve open.

Shown in Fig. 3 a, valve body 1 is cylindrical, shown in Fig. 3 b, and valve open when valve body rotates counterclockwise, and valve closing when clockwise rotating.

Shown in Fig. 4 a, 2 fluid outputs are arranged on the valve body 1, difference external fluid discharge pipe 8 and 9, spheroid 4 is positioned on the sealing gasket 5 of fluid discharge pipe 9 positions, and fluid discharge pipe 8 conductings, fluid discharge pipe 9 are closed; Shown in Fig. 4 b, valve body 1 is from the inverse position hour hands half-twist of Fig. 4 a, spheroid 4 be rolled into the sealing gasket 5 of fluid discharge pipe 8 positions ' on, fluid discharge pipe 9 conductings, fluid discharge pipe 8 are closed.
