Description

Petroleum pipeline valve body convenient to maintain Technical Field The utility model relates to the technical field of pipeline valve bodies, in particular to a petroleum pipeline valve body convenient to maintain. Background Petroleum pipeline valve bodies are key components in petroleum transportation and distribution systems, and are mainly used for controlling and regulating petroleum flow, and play a vital role in the petroleum industry, so that petroleum can be safely and effectively transported under different pressure and flow conditions. Under the normal condition of the traditional petroleum pipeline valve body structure, the rotary handle mechanism is connected with the valve body by adopting a flange connection mode, a plurality of bolts are required for fixing and fixing in the flange connection mode, when the rotary handle mechanism needs to be maintained, the rotary handle mechanism needs to be disassembled, and can be detached from the valve body only by disassembling the bolts. Disclosure of utility model The utility model aims to provide a petroleum pipeline valve body convenient to maintain, which solves the problems that the traditional petroleum pipeline valve body needs to be disassembled by a plurality of bolts to disassemble a rotary handle mechanism from the valve body, the process is time-consuming and labor-consuming, and the maintenance time cost and the labor cost are increased. In order to solve the technical problems, the utility model is realized by the following technical scheme: The utility model relates to a petroleum pipeline valve body convenient to maintain, which comprises a valve body and a rotary handle mechanism, wherein a first connecting flange is fixedly arranged on one side of the valve body, a second connecting flange is fixedly arranged on the other side of the valve body, a connecting mechanism is fixedly arranged on the upper surface of the valve body, a mounting mechanism is fixedly arranged on the outer surface of the rotary handle mechanism, and the connecting mechanism is connected with the mounting mechanism; the connecting mechanism comprises a fixed ring, a mounting groove and a semicircular sealing gasket, wherein the fixed ring is fixedly arranged on the upper surface of the valve body, the mounting groove is formed in the upper surface of the fixed ring, and the semicircular sealing gasket is symmetrically arranged on the inner wall of the mounting groove. Further, the connecting mechanism further comprises first connecting plates, a group of first connecting plates are symmetrically arranged on the peripheral side face of the fixing ring, and the number of each group of first connecting plates is fixed to be two.
