TECHNICAL FIELD
[0001] The utility model belongs to the grain storehouse and other grain storage sealing technical field, concretely relates to a general gate valve water tightness detection device. BACKGROUND
[0002] Under the background of national high standard grain storehouse construction, the air tightness of grain storehouse is particularly key. Therefore, in the process of grain storage, heat generation, aging and deterioration will inevitably occur, thereby affecting the quality of grain, therefore, in the process of grain storage, the grain storehouse must be fumigated or ventilated in time. Ventilation treatment can transfer the heat and moisture of grain to the outside air, which can effectively reduce the harm of heat generation and moisture evaporation of grain, reduce the aging and deterioration of grain, and reduce the economic loss of grain storage enterprises, therefore, ventilation treatment needs to open the gate of the grain storehouse to send air to the grain storehouse. Fumigation treatment is to introduce fumigation agent into the grain storehouse, and the fumigation agent circulates in the grain storehouse to kill bacteria, insects, insect eggs and microorganisms in the grain. If the fumigation agent leaks in the early stage of fumigation, it will cause personal injury and pollution, therefore, when fumigating the grain storehouse, the grain storehouse must be kept airtight, which has high requirements for the air tightness of the grain storehouse.
[0003] Therefore, the air tightness test of the grain storehouse needs to be carried out when the grain storehouse is completed and accepted. After closing all the gate valves of the grain storehouse, pressure gas is introduced into the grain storehouse to check whether there is leakage, so as to detect the air tightness of both sides. To ensure the air tightness of the grain storehouse, the air tightness of each gate valve of the grain storehouse must be ensured, which has high requirements for the air tightness of the gate valve of the grain storehouse, and the air tightness of the gate valve of the grain storehouse must be detected to ensure the sealing effect. At present, the sealing effect of the gate valve of the grain storehouse is usually detected by water tightness test method, which is simple and convenient to operate and low in cost. However, there is no special equipment for water tightness test at present, therefore, when the gate valve is tested by water tightness test, water is usually directly added in the groove cavity formed by the gate plate and the shell of the gate valve, and then whether there is water leakage under the gate plate is observed to determine the sealing effect of the gate valve. However, the height of the groove cavity formed by the existing gate valve is limited, which cannot meet the requirement of the national standard that the air tight gate valve is tested under 1000Pa pressure.
