[0002] The working principle of existing drain valve is as follows: by people or machine to button 1 ' (as figure 1 As shown), after a certain force is applied, the pressing rod of the button 1' contacts the end of the driving arm 4' of the swing arm 3' and pushes the driving arm 4' of the swing arm 3' to move downward, and the swing arm 3' passes through the shaft 5' and The valve body 6' rotates relatively, and drives the lifting arm 7' to lift the water stop mechanism 8' through the torque relationship. When the water stop mechanism 8' rises to the maximum height of the design (such as figure 2 state shown), the water stop mechanism 8' stops rising due to the limitation of the mechanism, and the water in the toilet tank continues to drain during this process. 'Continuously under the action of the driving arm 4' is in the open state, the water in the water tank continues to be discharged from the drain port, and the amount of discharged water cannot be controlled by the control mechanism of the drain valve, which leads to unstable discharge of the drain valve and also causes water resources waste of

Embodiment 1

[0049] Embodiment one, see Figure 3 to Figure 11As shown, a drain valve with a decoupling mechanism of the present invention includes a pressing mechanism, a valve body 7, a swing arm 2, a water stop mechanism 5, a control mechanism 8 and a base, and the pressing mechanism includes a button 1 and a button bracket 4. The button 1 is installed on the button bracket 4, the swing arm 2 and the control mechanism 8 are respectively arranged in the valve body 7, and the inner sleeve of the water stop mechanism 5 is connected to the swing arm 2; the present invention also includes a decoupling mechanism, the button 1 Drive the swing arm 2 through the uncoupling mechanism; the uncoupling mechanism includes a swing shaft 3 and a slider 33, the swing shaft 3 includes a rotating end 31 and a cantilever 32, wherein the rotating end 31 is provided with a rotating shaft post 311, on the key 1 is provided with a shaft hole 11 corresponding to the shaft post 311. Through the rotating shaft p...

Embodiment 2

[0057] Embodiment 2, a drain valve with a decoupling mechanism of the present invention, differs from Embodiment 1 in that the end of the cantilever 32 of the pendulum shaft 3 is not hinged on the slider 33, but pressed against the slider 33 The upper end of the slider 33 and the lower end of the slider 33 are pressed against the driving arm 21 of the swing arm 2; the button 1 is provided with a chute 13 for the slider 33 to slide vertically. The lower end of the slider 33 is provided with an inclined surface, the key 1 is driven by the spring force to reset the pendulum shaft 3, and the pressure block is subjected to the action of gravity to make the pendulum shaft 3 rotate and give way through the inclined plane, and the slide block 33 is reset.

Embodiment 3

[0058] Embodiment 3, a drain valve with a decoupling mechanism of the present invention is different from Embodiment 1 in that: the decoupling mechanism includes a rotary block 9 connected to the key 1 and a key bracket 4 that is horizontally rotatable The upper inclined surface 43 and the lower inclined surface 44, one end of the rotary block 9 is pressed against the driving arm 21 of the swing arm 2, and the other end of the rotary block 9 is matched with the upper inclined surface 43 and the lower inclined surface 44, when When the key 1 slides downward in the key bracket 4, the key 1 drives the turn block 9 to move downward, and when the turn block 9 descends to the first position, the other end of the turn block 1 touches the lower slope 44 on the key support 4, The turn block 9 rotates, and one end of the turn block 9 breaks away from the driving arm 21 of the swing arm 2; when the key 1 rises, the turn block 9 rises to the second position along with the key 1, and the ot...

Abstract

The invention discloses a drainage valve with an unhooking mechanism. The drainage valve comprises a pressing mechanism, a valve body, a swing arm, a water stopping mechanism and a base, the swing arm is arranged in the valve body, an inner sleeve of the water stopping mechanism is connected to the swing arm, the drainage valve further comprises the unhooking mechanism, the pressing mechanism drives the swing arm through the unhooking mechanism, the unhooking mechanism is separated from a drive arm when the pressing mechanism slides downwards to the designed position, and the unhooking mechanism resets when the pressing mechanism returns to the original position. The unhooking mechanism is mounted below the pressing mechanism of the drainage valve, so that the pressing mechanism stops the pressing action on the drive arm after the drive arm of the swing arm descends to certain height, the water stopping mechanism normally stops water, and the water discharge of the drainage valve is stable.

Description

technical field [0001] The invention relates to a drain valve, in particular to a drain valve with a decoupling mechanism. Background technique [0002] The working principle of existing drain valve is as follows: by people or machine to button 1 ' (as figure 1 As shown), after a certain force is applied, the pressing rod of the button 1' contacts the end of the driving arm 4' of the swing arm 3' and pushes the driving arm 4' of the swing arm 3' to move downward, and the swing arm 3' passes through the shaft 5' and The valve body 6' rotates relatively, and drives the lifting arm 7' to lift the water stop mechanism 8' through the torque relationship. When the water stop mechanism 8' rises to the maximum height of the design (such as figure 2 state shown), the water stop mechanism 8' stops rising due to the limitation of the mechanism, and the water in the toilet tank continues to drain during this process. 'Continuously under the action of the driving arm 4' is in the open...
