Problems solved by technology

In this case, the traditional square check valve is bulky, heavy, and inconvenient to install; and the square structure itself results in large blade area and weight, and the torque required for opening and closing is also high. , the positions of the four corners are dead corners, which are prone to turbulent flow and affect the transportation and flow of gas, thus resulting in high pressure loss and no energy saving in the traditional square check valve; poor

Abstract

The invention discloses a composite material special-shaped air pipe check valve for a circular gas pipeline in the technical field of check valves. The composite material special-shaped air pipe check valve comprises a check valve body, the check valve body comprises a circular valve body part and a square valve body part, an upper blade, a middle blade and a lower blade are arranged on the inner side of the check valve body, the upper blade, the middle blade and the lower blade are all connected with rotating shafts, the rotating shafts are rotationally arranged in the check valve body, sealing sleeve caps are arranged at the outer ends of the rotating shafts, three limiting baffles are arranged on the inner side of the check valve body, and a sealing baffle is arranged on the inner side of the check valve body. The size of the whole check valve body can be reduced, manufacturing materials and manufacturing cost are reduced, transportation, installation and maintenance are easy, machining is conducted through a mold and a winding method, manufacturing is convenient and fast, the appearance is attractive and elegant, the opening torque of valve blades is reduced by reducing the weight, the influence of part of structural dead angles on gas conveying is eliminated, and the pressure loss of the check valve body is reduced.

Description

technical field [0001] The invention relates to the technical field of check valves, in particular to a composite material special-shaped air duct check valve used for circular gas pipelines. Background technique [0002] With the rapid development of the domestic environmental protection industry, the demand for environmental governance and environmental protection facilities and equipment is gradually increasing, especially in the field of waste gas treatment. The safety, energy saving, airtightness and stability of the air duct check valve in the waste gas treatment system It is directly related to the normal operation of the entire processing system. The air duct check valve is mainly used when multiple fans share a delivery pipeline, and is generally installed at the air outlet of the fan. [0003] The traditional composite air duct check valve usually adopts a square valve body structure. When the external air duct is square, it can be directly connected. However, whe...
