Problems solved by technology

[0003] The existing gas pressure relief valve has a design structure without a dead point of the connecting rod. This structure cannot guarantee the gas pressure relief valve to achieve complete discharge performance. When the valve is in a dangerous state or in an overhaul state, the discharge with a small opening cannot meet the requirements. It is easy to cause equipment damage caused by high temperature gas pressure, and even cause harm to the human body

Abstract

The invention discloses a coal gas pressure release valve with a double-connecting-rod structure, and belongs to the technical field of valves. The coal gas pressure release valve comprises a valve seat, wherein a valve cover is detachably connected to the top surface of the valve seat, a swing arm is installed on one side of the valve seat, two sides of the swing arm are connected with the surfaces of the two sides of the valve seat through the double-connecting-rod structure, one end of the swing arm is provided with a hydraulic cylinder, and the other end of the swing arm is provided with aspring cylinder. According to the valve, through the coal gas pressure release valve with the double-connecting-rod structure, the driving effect of the hydraulic cylinder is increased, when the valve is in a dangerous state or an overhauling state, the small-opening-degree releasing cannot meet the requirements, the hydraulic cylinder acts to drive the swinging arm to act, the swinging arm drives the connecting rod to rotate relative to a hinge point of a support, the valve cover is opened, and the purposes of safe bleeding and pressure relief are achieved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a gas pressure relief valve with a double-link structure. Background technique [0002] The gas pressure relief valve adjusts the flow of the medium by controlling the opening of the opening and closing parts in the valve body to reduce the pressure of the medium. Within the range, and spray cooling water into the valve body or behind the valve to reduce the temperature of the medium. [0003] The existing gas pressure relief valve has a design structure without a dead point of the connecting rod. This structure cannot guarantee the complete discharge performance of the gas pressure relief valve. When the valve is in a dangerous state or in an overhaul state, the discharge with a small opening cannot meet the requirements. It is easy to cause equipment damage caused by high temperature gas pressure, and even cause harm to the human body. To this end, we propose a gas pressure re...
