Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1 and 2, the utility model discloses an automatic water level control test water tank, which comprises a test water tank 1, a lifting assembly 2, a sample placing frame 3, a water level drain valve 4, a floating ball liquid level control valve 5, a drain valve 6 and wheels 7, wherein:
referring to fig. 1 and 2, a drain valve 6 is designed at the bottom of a test water tank 1, a lifting assembly 2 is connected to the top of the test water tank 1, the lifting assembly 2 is connected to a sample placing frame 3, a floating ball liquid level control valve 5 is designed on one side of the upper portion of the test water tank 1, a water level drain valve 4 is designed on the other side of the upper portion of the test water tank 1, and a wheel 7 convenient to move is further arranged at the bottom of the test water tank 1.
The float level control valve 5 comprises a valve core 51, a valve rod 52 and a float ball 53, wherein the float ball 53 is connected to one end of the valve rod 52, and the other end of the valve rod 52 is hinged with a piston in the valve core 51. The valve core 51 is provided with a water outlet 511 and a water inlet 512, the water inlet 512 is connected with an external water pipe for water inlet, and a piston in the valve core 51 moves between the water outlet 511 and the water inlet 512.
When the water level of the test water tank 1 is low, the floating ball 53 reduces along with the water level, the valve rod 52 for fixing the floating ball 53 drives the piston in the valve core 51 to be pulled outwards, so that a gap is formed between the valve core 51 and the piston, and tap water enters the test water tank 1.
When the water level of the test water tank 1 is at a set height position, the piston in the valve core 51 is pushed inwards to the valve core 51 by the force generated by the rising of the floating ball 53 along with the water level through the valve rod 52, the sealing rubber gasket is arranged at the top end of the piston, the water outlet 511 in the valve core 51 is processed to be smooth, when the buoyancy of the floating ball 53 exceeds the pressure of tap water, the piston provided with the sealing rubber gasket is abutted against the water outlet 511 in the valve core 51 for sealing, and the tap water cannot enter the test water tank 1.
The valve rod 52 and the floating ball 53 are made of stainless steel, so that the valve rod is corrosion-resistant, rustless, safe and environment-friendly. The valve core 51 is made of copper material, and has high temperature resistance, corrosion resistance and long service life.
Referring to fig. 1 and 2, when the device is used in daily experiments, a sample to be tested is placed on the sample placing frame 3 according to the requirements of an instruction book, and the test sample and the sample placing frame 3 are immersed into the bottom of the test water tank 1 through the lifting motor 21. And closing a drain valve 6 at the bottom of the test water tank 1, opening a floating ball liquid level control valve 5 above the test water tank 1 for water injection, and simultaneously opening a water level drain valve 4 to keep the test water tank normally open. When the water is filled to the position of 1 meter, namely the position of the water level drain valve 4, the floating ball liquid level control valve 5 is automatically closed, and the water supply is stopped. After the test is finished, the test sample is lifted and taken out by the lifting motor 21. When taking out the test sample or the sample placing frame 3, the water level is reduced, the floating ball liquid level control valve 5 automatically starts water injection until reaching the one-meter water depth position, when reaching the one-meter water depth position, if water injection is continued, redundant water can be automatically discharged from the water level drain valve 4, and meanwhile, the floating ball liquid level control valve 5 automatically cuts off water inlet to stop water injection. If the volume of the placed test sample is larger than that of the previous test sample, redundant water can be automatically discharged through the water level drain valve 4, so that the test water level automatically keeps the depth of water of one meter, and if the volume of the placed test sample is smaller than that of the previous test sample, the floating ball liquid level control valve 5 automatically opens for water injection until the water level rises to one meter and is automatically closed.
If the test water tank is not used for a long time, the tap water pipe connected with the floating ball liquid level control valve 5 and the water level drain valve 4 are closed, the drain valve 6 is opened, the water in the test water tank 1 is emptied, and the test water tank is kept dry.
The test water tank 1 is additionally provided with a floating ball liquid level control valve 5 and a water level drain valve 4 on the basis of the prior art, and the test water level can be automatically controlled, so that the test water level is always automatically kept one meter; the problem that the test sluice is shut down manually is solved, the test efficiency is improved, and the accuracy and the effectiveness of the test result are improved. Through increasing balancing weight 31 on the basis of current sample rack 3, can ensure that sample rack 3 can be fast steady sink to test water tank 1 at the bottom, solved sample rack 3 slowly descend and unstable problem. Under the condition that the floating ball liquid level control valve 5 is arranged, only the water gate of the tap water pipe and the water level drain valve 4 need to be opened when a test is needed, the water gate does not need to be opened and closed frequently by a tester in subsequent use, the position of a test sample is not needed to be adjusted frequently, the operation difficulty of the tester is effectively reduced, and the test efficiency is improved. Because a tester does not need to find the placement position of the test sample, the accuracy and the effectiveness of the test result are effectively improved.
