Three-way discharging ball valve

Abstract

The invention discloses a three-way discharging ball valve. The three-way discharging ball valve is characterized in that a valve body (4) is provided with an inlet (27) and a first outlet (28) and a second outlet (17), the valve body (4) is internally provided with a ball core (10), and a lining (9) is arranged between the ball core (10) and the valve body (4); the upper and lower ends of the ball core (10) are respectively provided with a seal ring (8), the ball core (10) is connected with a handle (1) and is provided with a spacing plate (11), and the valve body (4) is provided with a circular cylinder (13) which is correspondingly spaced with the spacing plate (11); and the ball core (10) is provided with a ring channel (23), and the ball core (10) is driven by the handle (1) to cause the ring channel (23) to be communicated with the inlet (27) and the first outlet (28) on a phase position and can cut off the inlet (27) and the second outlet (17), the inlet (27) and the second outlet (17) are communicated on the other phase position, and the inlet (27) and the first outlet (28) are cut off. The three-way discharging ball valve provided by the invention has the advantages that the operation is convenient, the labour intensity is low, the seal is good, the volume is small, the weight is light, and the downhole installation transportation is convenient.

Description

technical field [0001] The invention relates to a valve, in particular to a three-way unloading ball valve. Background technique [0002] The unloading valves used for backfilling the three-fork unloading ports in existing mines are gate-type structures, and each set of unloading pipes requires two valves. When one valve is opened for unloading, the other valve must be closed at the same time; therefore, The operation is cumbersome and labor-intensive; the gate structure valve is not well sealed, and the mud is easy to leak, polluting the operating environment and endangering the health of the operators. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-way unloading ball valve with convenient operation and low labor intensity. [0004] In order to solve the above-mentioned technical problems, the three-way unloading ball valve provided by the present invention has an inlet, a first outlet, and a second ou...
