Novel wide-necked two-way valve with mechanical sealing function

Abstract

The invention discloses a novel wide-necked two-way valve with a mechanical sealing function. The novel wide-necked two-way valve comprises a feeding pipe and discharging pipes. The discharging pipescomprise the first discharging pipe and the second discharging pipe. One end of the first discharging pipe is connected with one end of the second discharging pipe in a crossed mode through inclined cuts, and an inclined circular connection port is formed. A triangular fixing support is arranged at the joint of the first discharging pipe and the second discharging pipe. The circular connection port is connected with the feeding pipe through a flange. A conical valve plug is arranged in the circular connection port. One end of the conical valve plug is arranged in a wide-necked way and is arranged in the circular connection port for being cooperatively used with the circular connection port. An elliptic hole which is cooperatively used with the inclined cuts for for enabling the feeding pipe to communicate with the discharging pipes is formed in the conical valve plug. The other end of the conical valve plug penetrates through the first discharging pipe and the second discharging pipe and is connected with a screw which is arranged on the triangular fixing support for rotating the conical valve plug. Through the conical valve plug, the passage conversion connecting mode of the feeding pipe and the discharging pipes is changed, the pressure an inlet pipe during passage conversion is decreased, passages are automatically switched through a motor, and thus operation is convenient.

Description

Technical field: [0001] The invention relates to a device for automatically changing pipeline passages, in particular to a new wide-mouth double-way valve with mechanical seal. Background technique: [0002] At present, most of the existing two-way valve replacement valve plugs in my country are U-shaped, with poor sealing performance and bloated appearance. The inlet is completely closed when the channel is changed, which may cause material blockage in the delivery pipeline. For related equipment The use of the adverse effects for such a situation. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new type wide-mouth double-way valve with a mechanical seal that has a simple structure and reduces the pressure of the inlet pipeline when switching channels. [0004] The technical solution of the present invention is: a new type wide-mouth two-way valve with mechanical seal, i...
