Triple Eccentric Butterfly Valve is widely used in the market because of its hard characteristics and good sealing performance of soft sealing butterfly valve. We all know that any use of goods need to be maintained, in fact, the triple eccentric butterfly valve is no exception, but many customers do not know how to use the triple eccentric butterfly valve in the process of maintenance, let's talk to you about the maintenance of Triple Eccentric Butterfly Valve.
Triple Eccentric Butterfly Valveare used only for full opening or full closing, and flow regulation is not allowed, so as to avoid erosion of the sealing surface and accelerate wear and tear. There is an inverted sealing device in the gate valve and the upper thread globe valve. The tightening of the upper position of the handwheel can prevent the leakage of the medium from the filler.
2. Hard-sealed butterfly valves should always be kept clean in use. Drive threads must be lubricated regularly. When faults are found, they should be stopped immediately to find out the causes and clear up the faults.
3. The bolts of packing gland should be tightened evenly, and should not be pressed askew, so as to avoid damaging the stem movement or causing leakage.

4. Before installation, it is necessary to carefully check the pressure of the valve mark, whether the diameter meets the requirements of use, eliminate the defects caused by the transportation process, and eliminate the dirt of the valve parts.

5. Valves stored for a long time should be inspected regularly. The exposed processing surfaces should be kept clean and dirt removed. When stored, ball valves should be blocked at both ends and open. Pneumatic butterfly valves and both ends of passages should be blocked and closed. They should be stored neatly in indoor ventilated and dry places. Stacking or open storage are strictly prohibited. 。
6. When installed, the valve can be directly installed in the pipeline according to the connection mode. Generally, it can be installed in any position of the pipeline, but it needs easy operation and maintenance. It should be noted that the medium flow direction of the globe valve should be under the longitudinal valve disc, and the lift check valve can only be installed horizontally.
7. Handwheel should be used when hard-sealed butterfly valve is opened or closed. Do not use lever or other tools to avoid damaging valve parts. The handwheel rotates clockwise to close and vice versa to open.
The service life of the Triple Eccentric Butterfly Valve will be prolonged and the efficiency of the Triple Eccentric Butterfly Valve will be improved to a greater extent if the Triple Eccentric Butterfly Valve is maintained and maintained regularly in use.
