Maintenance and repair of butterfly valve with expansion joint

Reinforcement by means of butterfly valve retrofitted expansion joint articulation splicing. Where the crack before reinforcement can be drilled should be drilled. The butterfly valve plus expansion joint in the force of the situation, the tension is applied and conflict force to transfer, the general butterfly valve plus expansion joint in the tightening of the screw cap will have tension and is still very small, butterfly valve plus expansion joint not only in the use of a large strength and butterfly valve plus expansion joint can also be applied to a very large tension.
 
This can make a lot of pressure between the articulated components, the direction of the screw is presented in the conflict, the quality of the butterfly valve plus expansion joint and the anti-slip coefficient are able to affect the bearing capacity of the butterfly valve plus expansion joint. Because the force is different, so in the accounting approach is also different, butterfly valve plus expansion joint small standard is M12, we often use in the construction is M16-M30, if beyond this standard then butterfly valve plus expansion joint function is not good, in the planning to be used with caution. Butterfly valve retrofit expansion joint articulation splicing method for reinforcement. The crack before reinforcement should be drilled where it can be drilled. The butterfly valve plus expansion joint in the force of the situation, the tension is applied and conflict force to transfer, the general butterfly valve plus expansion joint in the tightening of the screw cap will only have tension and is still very small, butterfly valve plus expansion joint not only in the use of a great strength and butterfly valve plus expansion joint can also be applied to a very large tension.
