Supply
rubber ball water plugs for pressure testing of building pipelines
, used for pressure testing and testing of building sewer pipes. They are made of high-quality rubber materials. When using, put the
water plugs
in In the pipe, it can seal water immediately after being inflated. The water sealing plug can withstand more than one atmosphere of pressure and can be reused.
The water-closing airbag used for pressure sealing in pipeline testing is made of composite materials newly developed by our company. It has strong pressure resistance and sealing effect. It has been proven by many construction units across the country that the quality of this product is Reliable and stable in performance, it is an ideal tool for pipeline sealing construction.
The components of the Xiangpai water-blocking rubber plug and pipeline air plug
The water-closing plug is equipped with a pressure gauge, safety valve, ball valve, and three-way joint
The shell of the pressure gauge is fully sealed with plastic Gauge, the diameter is not larger than
The measuring range of the pressure gauge is (.) High accuracy, the minimum division is.
How to use the water plug
Prepare the accessories of the water plug aeration device first Make the combination and check the tool for air leakage. Place the water-closing plug in a bucket filled with water and hold it down. Inflate the water-closing plug with an air pump to check whether the water-closing plug is leaking.
Open the inspection port of the riser, slowly push the water plug upwards from the opening, and then inflate the water plug so that the water plug is in close contact with the inner wall of the pipe and the water will not leak. (The experience is based on Take the model as an example. When inflating, shake the air bag by hand until the air bag is just combined with the tube wall, and then slowly inflate it with a pump. At this time, the air bag can withstand the natural water pressure of the upper layer. The operator inflates the lower layer and fills the upper layer with water. Note that water plugging should be avoided at the joints of riser pipe fittings because there are seams on the inner wall there, which affects the tightness of the water plugging. This prevents the water blockage from expanding to one side and the air pressure cannot be pumped up. If the air continues to be inflated, the water blockage will be broken. For cast iron drainage pipes, it is required to clean the sand and make the inner wall smooth. No burrs are allowed, otherwise it will affect the water sealing and even puncture the capsule. Open the inspection port of the riser, slowly push the water plug upward from the opening, and then inflate the water plug so that the water plug is in close contact with the inner wall of the pipe to ensure that the water does not leak. Various specifications of the water plug must be installed accordingly. When used in pipelines, small ones cannot be used instead of large ones.
Fill the water filling port on the floor (you can also use the inspection port) to the height of the floor, and then check the water filling pipes and pipe fitting interfaces one by one. If any leakage is found, make a mark and repair it after drainage. For example: It is a flexible interface with rubber ring, and the leaking interface can be repaired with water-tightening bolts. If there is no leakage point in the inspection of the irrigation pipeline, the water level can be stabilized, and the irrigation time lasts for 10 minutes. If the irrigation liquid level does not drop for 10 minutes, it is considered qualified.
. Deflate the water plug, and then slowly pull out the water plug. Be careful not to damage the water plug.
