Problems solved by technology

[0002] In the automatic control of modern factories, the regulating valve plays a very important role. The production of these factories depends on the correct distribution and control of the flowing medium. When the user uses the regulating valve, the high-pressure medium is compressed into a low pressure through the regulating valve. The medium is then used in the process pipeline. When the process pipeline is suspended, the medium pressure at the outlet of the regulating valve will continue to rise, and when the medium pressure rises to a certain value, the disc sealing surface of the regulating valve and the valve seat will The sealing surfaces are in contact with each other. Due to the small sealing specific pressure, the sealing of the regulating valve is poor, and the medium on the inlet side of the regulating valve will leak to the outlet side of the regulating valve. The pressure of the medium on the outlet side of the regulating valve will continue to rise, and it is easy to form a regulating valve. Accidents such as pipe rupture or explosion on the outlet side

Abstract

The invention discloses a regulating valve. The regulating valve comprises a valve body, a valve cavity is formed in the valve body, a valve seat plate is arranged in the valve body, the valve seat plate divides the valve cavity into an upper valve cavity body and a lower valve cavity body, and an inlet pipe and an outlet pipe are arranged on the side face of the valve body; a valve hole is formedin the valve seat plate; a valve deck is fixedly installed at the upper end of the valve body, an unloading hole is formed in the outer side face of the valve deck, a protruding column is arranged onthe inner side of the valve deck, a first sliding hole is upwards formed in the lower end of the protruding column, a second sliding hole is upwards formed in the blind end of the first sliding holein the protruding column, a valve clack is slidably connected in the first sliding hole, a sliding block is arranged on the valve clack, a first cavity is formed in the first sliding hole, a second cavity is formed in the second sliding hole, and a pressure regulating spring is arranged in the second cavity; an annular unloading groove is formed in the lower end of the valve clack; and a valve control assembly is arranged in the valve deck. The regulating valve not only is reliable in sealing, but also can prevent the outlet side pipeline from being broken or exploded due to overlarge pressure.

Description

technical field [0001] The invention belongs to the technical field of regulating valves, in particular to a double-seat regulating valve. Background technique [0002] In the automatic control of modern factories, the regulating valve plays a very important role. The production of these factories depends on the correct distribution and control of the flowing medium. When the user uses the regulating valve, the high-pressure medium is compressed into a low pressure through the regulating valve. The medium is then used in the process pipeline. When the process pipeline is suspended, the medium pressure at the outlet of the regulating valve will continue to rise, and when the medium pressure rises to a certain value, the disc sealing surface of the regulating valve and the valve seat will The sealing surfaces are in contact with each other. Due to the small sealing specific pressure, the sealing of the regulating valve is poor, and the medium on the inlet side of the regulatin...
