Description

Liquid control valve and its liquid stop

The present invention relates to a liquid control valve, in particular to a liquid control valve which can control the liquid level by raising and lowering the float ball, its adjusting rod and the liquid stopper.

Please refer to FIG. 1, which is a conventional liquid control valve 9 disclosed in Patent No. M554183 published by the Republic of China. The liquid control valve 9 can be used in a liquid storage container such as a water tower, a liquid storage tank, etc. The control valve 9 is provided with a main body 91, the main body 91 has a water inlet 9a and a water outlet 9b, the inner edge of the main body 91 is provided with a protruding wall 911, and a valve stem 92 and a water stop ring 93 are arranged inside the main body. , a water stop ring seat 96, and a pull rod 94 extending out of the body, the outer edge of the body is connected to a floating ball rod 95, one end of the floating ball rod 95 has a floating ball 951 that can float on the liquid surface, and the floating ball An adjustment device is arranged between the rod 95 and the pull rod 94. The adjustment device includes a first fixing member 97, a rotatable adjustment member 98 and a second fixing member 99. The first fixing member 97 is connected by a first pivot The contact point P1 is pivotally connected with the float rod 95 , and the second fixing member 99 is pivotally connected with the pull rod 94 by a second pivot point P2 .

When the liquid level of the liquid storage container drops, the float rod 95 can push the pull rod 94, so that the protrusion 941 of the pull rod 94 leaves the bottom of the valve rod 92, so that the water pressure from the water inlet 9a can force The water stop ring 93 is separated from a protruding wall 911 of the main body 91, so that the liquid can be replenished in the water storage container, so that the liquid level can be raised. When the liquid level rises to a predetermined height, the float rod 95 can pull the pull rod 94, so that the protrusion 941 of the pull rod 94 pushes the bottom of the valve rod 92, and the water stop ring 93 can be connected to the bottom of the valve rod 92. The protruding wall 911 is in close contact with each other, so that the liquid is no longer replenished in the water storage volume. device.

When the liquid storage container using the above-mentioned conventional liquid control valve 9 wants to change the liquid level, the first pivot point P1 and the second pivot point P2 are adjusted by rotating the adjusting member 98 When the distance becomes larger, the liquid storage container can have a higher liquid level, so that the liquid storage capacity of the water storage container can be increased. On the contrary, when the distance becomes smaller, the liquid storage container has only a lower liquid level, so that the liquid storage capacity of the liquid storage container can be reduced. When adjusting the adjusting member 98 to adjust the distance between the first pivot point P1 and the second pivot point P2, the movable strokes of the valve rod 92 and the water stop ring 93 will be changed at the same time, and the The protrusions 941 of the pull rod 94 form different pressures on the bottom of the valve rod 92 . When the adjustment member 98 is excessively adjusted and the distance between the first pivot point P1 and the second pivot point P2 is too small, the movable strokes of the valve rod 92 and the water stop ring 93 become smaller, so, When the liquid level drops, the water stop ring 93 cannot be completely separated from the protruding wall 911 or remains in a close contact state, so that the replenishing liquid from the inlet 9a cannot quickly drop or be replenished in the water storage container; on the contrary, when the first hinge When the distance between the contact point P1 and the second pivot point P2 is too large, the protrusion 941 of the pull rod 94 cannot push the valve rod 92 to rise to a higher position, so that the water stop ring 93 cannot connect with the protrusion 911 A gap is formed by being kept in a close contact state, and the liquid will continue to leak from the gap to the water storage container.

Please refer to FIG. 2. Furthermore, when the protrusion 941 of the pull rod 94 pushes the bottom of the valve rod 92 for a long time, since the protrusion 911 and the water stop ring 93 have only a small contact area, so , the water-stop ring 93 will be deformed due to long-term pressure, so that the water-stop ring 93 cannot achieve close contact and has a gap, so that the liquid will also leak from the gap to the water storage container.

In view of this, the conventional liquid control valve still needs to be improved.

In order to solve the above-mentioned problems, the purpose of the present invention is to provide a liquid control valve, which can improve the When the liquid level height of the water storage container is changed, the moving stroke of the liquid stopper will not be changed, so that the liquid stopper has a better effect of preventing leakage.

Another object of the present invention is to provide an adjusting rod of a liquid control valve, which can change the height of the liquid level by changing an included angle of the adjusting rod.

Another object of the present invention is to provide a liquid stopper for a liquid control valve, which can avoid deformation and leakage of the liquid stopper due to long-term use.

Referring to Figures 8 and 10, when the user wants to change the liquid level L of the liquid storage container, the user can loosen the screw 33 to make the adjustment arm 32 and the fixed arm 31 separate. The angle between them can be changed to change the height of the stop water level. Taking Fig. 4 as an example, rotating the adjusting arm 32 clockwise relative to the fixed arm 31 can increase the height of the liquid level; on the contrary, rotating the adjusting arm 32 counterclockwise relative to the fixed arm 31 can Decrease the height of this level. When changing the angle between the adjustment arm 32 and the fixed arm 31 , the adjustment rod 3 is only rotated relative to the fixed arm 31 by the adjustment arm 32 , and is pivoted to the linkage rod of the second pivot portion 15 . 4 series won't turn and the included angle between the driving arm 41 and the connecting arm 42 will not change, so as to avoid changing the movement stroke of the liquid stopper 2 .

To sum up, the liquid control valve and its adjusting rod and liquid stopper of the present invention only make the adjusting arm rotate relative to the fixed arm when changing the height of the water stop liquid level, and the linkage rod is pivotally connected to the The position of the second pivot part will not rotate, and the angle between the driving arm and the connecting arm will not change. In this way, the movement stroke of the liquid stopper will not be changed, thereby avoiding the failure of the liquid control valve. Water enters or achieves the effect of stopping leakage. In addition, the sealing body and the guiding member can also be connected to the third end surface of the guiding member by the first stop portion, in addition to the sealing member being in close contact with the first end surface of the guiding member through the lower surface of the sealing member. The stop part and the second stop part are in multiple close contact with the fourth stop part, which can achieve the best close contact, prevent leakage, and prevent liquid from leaking from the first container to the second container. effect of the chamber.
