Abstract

The utility model relates to a floating ring cover intake valve for a valve. The floating ring cover intake valve for a valve is used for automatically controlling the liquid level of a container. A floating body directly drives a ring cover valve to slide from top to bottom along a valve body, which can lead a water outlet to be opened or closed. The liquid level is automatically controlled. The closing force required by the valve is weak. Therefore, the utility model does not need a lever, etc. The reliability is enhanced, and the volume of the float body can be reduced. The intake valve of the utility model is suitable for the mode of the water inlet from the upper part and the mode of the water outlet from the lower part.

Description

Floating ring cover intake valve for valve

The utility model is a kind of inlet valve that is used for controlling automatically liquid level height in the container.

Lever distortion, pin wearing and tearing often take place, close fault such as dislocation in the long-term floating ball lever formula inlet valve that is used to control liquid level in containers such as flush toilet, roof tank, produce close ineffective, disadvantage such as water level is out of control.

The utility model floating ring cover valve inlet valve is to eliminate above-mentioned floating ball lever formula inlet valve fault, improves level control reliability in the container and develops.

This valve body (1) (referring to accompanying drawing 1) is the cylindrical body of end sealing, have (or a several) osculum (2) on the middle wall of cylindrical body, the valve (3) that the outer wall of tubular valve body (1) is with a garden annular has for the hole, garden that connects buoyancy aid (4) on it.The other end outer end diameter of valve body (1) is slightly less than footpath outside the middle cylinder, and has the screw thread of using for external water pipe on its outer wall.The footpath is slightly larger than footpath outside the middle cylinder outside the closed end of valve body (1).Valve (3) is put thereon with the end that buoyancy aid (4) connects.The water that water pipe supplied is flowed in the container by osculum (2) through valve body (1) inner chamber.When liquid level reached predetermined altitude in the container, buoyancy aid (4) come-up promoted loop overlapping shape valve (3) and upwards slides along valve body (1) outer wall.Treating that valve (3) rises to hides the osculum (2) on the valve body (1) when entangling, and osculum (2) just stops water filling in container.Reach the purpose of control liquid level.Because sleeved valve (3) upwards slides and hides the pressure of supply water that does not all directly bear the water source when entangling osculum (2) along valve body (1) outer wall, so the required buoyancy of closing is less.Respectively be provided with an annular spring groove (5-1) and (5-2) on valve body (1) osculum (2) the upper and lower outer wall, be in and jump ring (6) is housed in the jump ring groove (5-1) of osculum (2) top is used to place restrictions on valve (3) and goes up the sliding osculum (2) that surpasses.Be with spirality stage clip (7) on the wall outside the valve body (1) between jump ring (6) and the valve (3) and be used for when drawdown, make valve (3) increase the sharp downslide of decline mechanical compliance.

The closed top end of valve body (1) has the hexagon excrescence, and spanner is twisted when supplying by dress puts forth effort.

This floating ring cover valve inlet valve both can have been made inlet type as mentioned above by being loaded in the container, also can descend inlet type by being loaded in the container.(referring to accompanying drawing 2) valve (3) was put on the tube wall of external water pipe joint with the end that buoyancy aid (4) connects when following inlet type was pressed dress.But jump ring (6) should be contained in the jump ring groove (5-2) that now has been in osculum (2) top, still plays limiter valve (3) and excessively goes up sliding.Stage clip (7) also is enclosed within on valve body (1) outer wall between jump ring (6) and the valve (3).

The buoyancy aid of this floating ring cover valve inlet valve adopts the annular hollow body of endoporus greater than valve body (1), so that valve (3) is gone up around the power of cunning is even.

The utility model floating ring shell type valve adopts mode sliding on the direct control valve of buoyancy aid more simple in structure than floating ball lever formula inlet valve, has improved reliability.Owing to directly do not bear pressure of supply water during this sleeved valve closing osculum so the required power of closing is little.The buoyancy aid volume also can dwindle.

This floating ring cover valve inlet valve is common to inlet type or two kinds of differences of inlet type are by the dress mode down, and versatility is big.

Description of drawings:

Fig. 1: go up the floating ring shell type inlet valve of inlet type by dress.

Fig. 2: following inlet type is by the floating ring shell type inlet valve of dress.

Claims (2)

1, a kind of by buoyancy aid, valve, compositions such as valve body are used to control the inlet valve of liquid level height in the container, be primarily characterized in that this valve body (1) is end sealing and have the garden cylindrical shell of or several osculums (2) on the sidewall, the outer wall of valve body (1) is with the valve (3) of a garden ring-type, valve (3) connects with buoyancy aid (4), on valve body (1) the outer wall osculum (2), the below respectively has a ring-type jump ring groove (5-1) to reach (5-2), device jump ring (6) is with a double helix shape stage clip (7) on valve body (1) outer wall between jump ring (6) and the valve (3) in the jump ring groove of valve (3) top.

2, by the described inlet valve of claim 1, it is characterized in that buoyancy aid (4) is the annular hollow body of endoporus greater than valve body (1) external diameter.
