Abstract:
Provided is a flow line seal structure for a diverter valve, in which a seal is formed between an inner housing and an outer housing of the diverter valve that prevents mud from flowing backward into a drill pipe provided outside a drill bit and rising, prevents the rising mud from being ejected into a drilling site, and diverts a direction of the mud so as to refine and reuse the mud in the process of forming an oil well by rotation of the drill bit during drilling, and breakage is prevented during assembly, assembly is facilitated, and sealing effect is improved. According to the present invention, it is easy to assemble the outer housing, and it is possible to prevent damage to the sealing member when the outer housing is assembled, thereby efficiently forming a seal, and accordingly, a diverter valve with improved sealing effect can be manufactured.

Claim (Index 2):
The flow line seal structure of  claim 1 , wherein the sealing member ( 130 ) has an inner diameter smaller than an outer diameter of the sealing groove ( 120 ).
