Detailed Description

As shown in fig. 1 and 2; the mechanical time delay floating ball controller of the embodiment comprises: the valve comprises a valve body 1, a piston 4, a connecting rod 3 and a floating ball 2; one end of the valve body 1 is provided with a liquid inlet; referring to fig. 1, the liquid inlet is a top outlet of the valve body 1.

The bottom of the floating ball 2 is connected with the piston 4 through the connecting rod 3, and the piston 4 can be slidably sleeved in the valve body 1 through the liquid inlet and can slide up and down along the valve body 1; in general, the valve body 1 has a cylindrical cavity, and the piston 4 moves up and down in the cavity.

A liquid inlet channel 10 for feeding liquid is arranged in the valve body 1, and the liquid inlet channel 10 is connected with the liquid inlet; the floating ball 2 floats upwards to enable the piston 4 to ascend so as to block the liquid inlet; that is, the piston is raised so that the outlet of the liquid inlet passage 10 is blocked and the liquid inlet cannot be performed.

The connecting rod 3 is sleeved with a damper 60, and the damper 60 is fixed on the valve body 1.

Preferably, a flow guide channel 5 is arranged in the piston 4; the piston 4 blocks the liquid inlet so that the flow guide channel 5 is communicated with the liquid inlet channel 10.

As shown in fig. 1, the piston displaces the bottom of the cavity, and at the moment, the liquid inlet channel 10 is communicated with the liquid inlet, so that the liquid can be continuously fed, and the liquid in the high-pressure tank is continuously increased; the floating ball floats upwards along with the increase of the liquid, and the piston is driven by the connecting rod to slide upwards so as to close the liquid inlet.

As shown in fig. 2, the piston completely cuts off the communication part between the liquid inlet channel and the liquid inlet, so that the liquid in the liquid inlet channel flows into the flow guide channel in the piston, and the redundant liquid is discharged through the flow guide channel.

The mechanical delay floating ball controller of the invention controls the liquid level by the floating ball, when the floating ball does not float to the preset position, the piston is positioned at the lower part of the liquid inlet to ensure the continuous liquid inlet until the liquid inlet is blocked; and owing to the setting of attenuator, thereby avoid high pressure feed liquor in-process liquid level float to cause the accident of floater frequent action and damage case, still avoided the easy dead technical problem of card of piston when high pressure feed liquor starts.

The mechanical time delay floating ball controller of this embodiment, wherein, the upper end of valve body 1 still is provided with stopper 7, and this stopper 7 is located the top of piston 4 for after water conservancy diversion passageway and inlet channel intercommunication, avoid the piston to continue rebound under the floater vibration or other effects, the at utmost has avoided extra inlet liquid.

The mechanical time delay floating ball controller of the embodiment, wherein the top of the valve body 1 is provided with a support rod 6, and the damper 60 is installed on the valve body 1 through the support rod 6.

Specifically, the damper 6 includes: a constant speed gear and a bar tooth; the bar-shaped teeth are fixed on the connecting rod 3 along the numerical direction, and the constant speed gear is arranged on the valve body 1; the fixed speed gear is meshed with the strip-shaped teeth.

Therefore, mechanical damage and misoperation caused by oscillation of the floating ball when the liquid level fluctuates or the air pressure changes violently can be avoided.

The mechanical time delay floating ball controller of this embodiment, wherein, be connected with the overflow pipe on the water conservancy diversion passageway 5, when the piston come up to the top, this overflow pipe passes through water conservancy diversion passageway 5 with the inlet channel is linked together.

In the mechanical delay floating ball controller of the present embodiment, a plurality of liquid inlet channels 10 are provided in the valve body 1.
