Description

TECHNICAL FIELD

[0001] The utility model relates to valve technical field, concretely relates to a novel anti-swing floating water tank float ball valve. BACKGROUND

[0002] The water tank float ball valve is an automatic valve device for controlling the water level of a water tank, which is usually installed at the water inlet of the water tank. Its main function is to keep the water level in the water tank within a certain height range, avoiding the overflow or water shortage of the water tank. The existing water tank float ball valve generally comprises a valve, a float ball connected with the valve rod of the valve through a float ball connecting rod.

[0003] The working principle of the water tank float ball valve is that the float ball moves up and down with the change of the water level in the water tank, and the displacement is transmitted to the valve rod through the float ball connecting rod. When the water level rises, the float ball rises to drive the connecting rod to push the valve rod to close the valve. When the water level drops, the float ball drops, and the connecting rod pulls the valve rod to open the valve, realizing the opening and closing control of the valve, so as to maintain the water level in the water tank within a certain height range.

[0004] In the actual operation of the water tank float ball valve, the inventor found that after the float ball reaches the highest point, if the water level in the water tank does not change, the float ball will swing left and right on the water surface, and drive the valve rod to produce continuous shaking, resulting in the wear of the valve surface of the float ball valve, the valve cannot be closed tightly, and the closing function cannot be achieved, which often causes the water to overflow from the overflow port of the water tank, resulting in economic loss.

[0005] Therefore, the inventor believes that how to solve the above technical problems is a technical problem urgently needed to be solved by those skilled in the art.

Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present utility model.

[0023] With reference to Figures 1-4 In view of the problems in the prior art, the embodiments of the present utility model provide a novel anti-swing floating ball valve for floating water tank to solve the above technical problems, and the technical scheme is as follows.

[0024] The novel anti-swing floating ball valve for floating water tank comprises a valve 100, a floating ball 210, a counterweight module 310, a first floating ball connecting rod 220, a second floating ball connecting rod 320 and a locking module.

[0025] The first end of the first floating ball connecting rod 220 is hingedly connected with the valve rod 110 of the valve 100, and the second end of the first floating ball connecting rod 220 is connected with the bottom of the floating ball 210.

[0026] The lower end of the second floating ball connecting rod 320 is fixedly connected with the top of the counterweight module 310, the upper end of the second floating ball connecting rod 320 is fixedly connected with the locking module, and the locking module is locked on the first floating ball connecting rod 220.

[0027] The locking module comprises a U-shaped locking plate 330, a first bolt 340 and a second bolt 350, the bottom of the U-shaped locking plate 330 is fixedly connected with the upper end of the second floating ball connecting rod 320, and the first floating ball connecting rod 220 penetrates through the two arms of the U-shaped locking plate 330.

[0028] The first bolt 340 and the second bolt 350 are respectively penetrated in the two arms of the U-shaped locking plate 330, and the first bolt 340 and the second bolt 350 are located on the upper and lower sides of the first floating ball connecting rod 220.

[0029] The tail portions of the first bolt 340 and the second bolt 350 are connected with nuts, and the locking module is locked on the second floating ball connecting rod 320 by tightening the nuts.

[0030] It should be noted that, in actual use, the connecting position of the counterweight module 310 on the first floating ball connecting rod 220 can be adjusted according to the specific working condition of the water tank, the water flow condition and the swing characteristics of the floating ball 210 and other factors.

[0031] The adjustment mode is relatively simple, the nuts on the first bolt 340 and the second bolt 350 are loosened, the locking module is slid on the first floating ball connecting rod 220, and after being adjusted to a suitable position, the two arms of the U-shaped locking plate 330 are clamped by tightening the nuts on the first bolt 340 and the second bolt 350.

[0032] In the embodiment, the first floating ball connecting rod 220 is provided with an external thread, and the external thread is not shown in the drawings; the external thread of the first floating ball connecting rod 220 is connected with a limiting nut 230; the limiting nut 230 is located between the locking module and the floating ball 210. The limiting nut 230 plays a role of limiting and positioning, avoiding loosening and sliding down of the locking module due to loose connection.

[0033] In the embodiment, the counterweight module 310 is a cylindrical balloon 310; the cylindrical balloon 310 is filled with water.

[0034] In the embodiment, the material of the cylindrical balloon 310 is nitrile rubber material; the cylindrical balloon 310 is provided with a water injection valve.

[0035] The use method of the novel anti-swing floating water tank floating ball valve provided by the embodiment of the utility model is as follows:

[0036] (1) Liquid level rises: when the liquid level of the water tank rises, the floating ball 210 is lifted by the water buoyancy and rises, and the floating ball 210 drives the valve rod 110 of the valve 100 to move upwards through the first floating ball connecting rod 220, thereby pushing the valve to close and gradually reducing the water inflow into the water tank; in this process, the counterweight module 310 will try to keep the floating ball 210 stable during the rising process due to the action of gravity, reducing the left and right swing of the floating ball.

[0037] (2) Liquid level drops: when the liquid level of the water tank drops, the floating ball 210 drops with the water surface, and the valve rod 110 is pulled downwards through the first floating ball connecting rod 220, so that the valve is opened, the water inlet of the water tank is opened, and water flows into the water tank; similarly, the counterweight module 310 will play a stabilizing role during the floating ball descending process to prevent excessive swing of the floating ball.

[0038] (3) Liquid level is stable: when the liquid level of the water tank reaches the set height and remains unchanged, the floating ball 210 should be in a relatively stable position; at this time, the counterweight module 310 balances the water flow disturbance and other external forces that the floating ball 210 may be subjected to, reducing the left and right swing of the floating ball. Even if the floating ball is affected by some small external forces and tends to swing, due to the action of the counterweight module, the swing amplitude can be greatly reduced, so that the floating ball can be more stably maintained at the corresponding position, avoiding the valve surface wear caused by the valve rod shaking driven by the floating ball swing, and effectively preventing the water tank from overflowing.

[0039] The utility model discloses a novel anti-swing floating water tank float ball valve has the following beneficial effects: the utility model, design a kind of novel anti-swing floating water tank float ball valve, change the single ball control of water tank float ball valve by the original, change into single ball and column ball sac double ball control;Cylindrical ball sac is installed below first floating ball connecting rod, cylindrical ball sac can limit the left and right swing of floating ball after being filled with water, avoid the valve surface abrasion caused by the swing of floating ball driving valve stem to sway, effectively prevent the occurrence of water tank overflow condition.
