Detailed Description

Referring to fig. 1, an adjustable float valve for a cooling tower comprises a valve body 1, a valve core 11 is slidably disposed on an inner wall of the valve body 1, a valve cover 12 is fixed on the valve body 1, a sealing sleeve 13 is fixedly embedded on the valve cover 12, a valve rod 14 is slidably penetrated in the sealing sleeve 13, a lower end of the valve rod 14 is fixed to the valve core 11, an upper end of the valve rod 14 is fixed to a connecting plate 15, two sides of the connecting plate 15 are fixed to a support rod 17 through a first connecting rod 16, a cylinder 18 is slidably sleeved on the support rod 17, a float ball 19 is fixed to the cylinder 18, the closing capacity of the float ball 19 for driving the valve core 11 is improved by adopting a mode of two-side arrangement, and the situation that the valve core 11 is too heavy and the float ball 19 cannot drive.

Referring to fig. 1, the support rod 17, the cylinder 18 and the floating ball 19 are made of stainless steel, and the floating ball 19 is a hollow structure, so as to prevent corrosion in contact with water for a long time.

Referring to fig. 1, the second connecting rod 2 is fixed on two sides of the valve cover 12, the positioning sleeve 21 is fixed on the second connecting rod 2, and the support rod 17 and the positioning sleeve 21 are slidably arranged, so that a stable limiting effect is achieved, and the lifting stability is ensured.

Referring to fig. 1, the support rod 17 is provided with a limiting groove 22, a limiting block 23 is fixed on the inner wall of the positioning sleeve 21, and the limiting block 23 and the limiting groove 22 are slidably disposed.

Referring to fig. 1 and 2, the barrel 18 is provided with a positioning hole 3, a positioning pin 31 is slidably disposed in the positioning hole 3, and the positioning pin 31 is inserted into the positioning groove 33 to fix the barrel 18 and the support rod 17.

Referring to fig. 1 and 2, a spring 32 is wound on the positioning pin 31, and two ends of the spring 32 are respectively fixed to the positioning pin 31 and the barrel 18 to ensure the stretching and resetting of the positioning pin 31.

Referring to fig. 1 and 2, the supporting rod 17 is provided with a plurality of positioning grooves 33, and the positioning pin 31 is inserted into any one of the positioning grooves 33, so as to facilitate the relative telescopic fixation of the cylinder 18 and the supporting rod 17 and adjust the telescopic position of the floating ball 19.

The working principle of the scheme is as follows: when the telescopic position of the floating ball 19 needs to be adjusted, the positioning pin 31 is pulled outwards, so that the positioning pin 31 is separated from the current positioning groove 33 through the stretching of the spring 32, and the position of the floating ball 19 can be adjusted through the relative telescopic of the barrel 18 and the support rod 17.

When the positioning pin 31 corresponds to the positioning groove 33 of the new position, the positioning pin 31 is inserted into the positioning groove 33 by the restoring effect of the spring 32, thereby completing the position fixing of the floating ball 19.

When the valve core 11 needs to be lifted, the water level rises, so that the floating balls 19 float and rise, the two floating balls 19 have enough buoyancy, the valve core 11 and the valve body 1 are closed, and the limiting block 23 slides in the limiting groove 22, so that the slipping can be avoided.
