Description

Main network air pressure adjusting device of vibration-resistant elasticizer Technical Field The invention belongs to the technical field of chemical fiber texturing equipment, and particularly relates to an anti-vibration type texturing machine main network air pressure adjusting device. Background In the chemical fiber texturing process, the stability and sufficiency of the air pressure of a main network are important, and the air pressure directly influences the network degree and the product quality of spinning cakes. The existing main network air pressure system of the elasticizer generally has the following two technical bottlenecks: On the one hand, the pipeline pressure drop is overlarge, the pipeline from the air compression station to each elasticizer is particularly in the last section (such as DN50 pipeline before and after a pressure regulating valve) before entering a machine platform, and because the pipe diameter is thinner, larger flow resistance is generated on compressed air, so that the air compressor must set higher output pressure (such as 4.5 kg) to meet the actual use pressure (such as 3.5 kg) of the machine platform end, the pressure difference of up to 1 kg exists, the energy waste is caused, and meanwhile, the flow is limited, so that the system cannot meet the production requirement of 'heavy net' varieties with higher air pressure requirements. On the other hand, the pressure regulation is unstable, the existing system adopts a pneumatic pressure regulating valve, and the pressure regulation is convenient, but under the vibration environment of the elasticizer running for a long time, sensitive elements such as diaphragms, springs and the like in the system are easy to generate fatigue or micro displacement, so that the valve setting value slowly drifts, operators are required to inspect and regulate frequently, the fluctuation which is frequently and difficultly controlled accurately directly causes unstable network air pressure, and the pressure regulation is a potential risk source for causing fluctuation of product quality and even mass quality accidents. The conventional arrangement of the "DN50 pipe and pneumatic pressure regulating valve" described above does not allow a good balance between energy consumption and stability. Therefore, we provide an anti-vibration type elasticizer main network air pressure regulating device to solve the above problems. Disclosure of Invention The invention aims to provide an anti-vibration type elasticizer main network air pressure regulating device, which is characterized in that the flow resistance is reduced by increasing the nominal diameter of a pipeline from DN50 to DN80, a manual pressure regulating valve with a locking component is adopted to resist vibration drift, a reducing buffer mechanism and a damping energy consumption buffer mechanism are arranged in front of the valve to inhibit pressure pulsation, and a buffer surge tank is arranged behind the valve, so that the technical problems of high pipeline pressure drop, high energy consumption, unstable product quality caused by vibration influence of an air pressure regulating valve of an existing elasticizer main network air pressure system are solved. In order to solve the technical problems, the invention is realized by the following technical scheme: The invention provides an anti-vibration type elasticizer main network air pressure regulating device, which comprises a capacity-increasing air inlet pipeline, a capacity-increasing air outlet pipeline and a manual pressure regulating valve, wherein the air inlet end of the capacity-increasing air inlet pipeline is connected with an upstream air supply pipeline, the nominal diameter of the capacity-increasing air inlet pipeline is DN80, compared with the prior DN50 pipeline, DN80 can obviously reduce the conveying pressure drop, the air outlet end of the capacity-increasing air inlet pipeline is connected with the inlet end of a variable diameter buffer mechanism through a flange, the air outlet end of the variable diameter buffer mechanism is connected with the air inlet of the manual pressure regulating valve through a flange, the damping energy consumption buffer mechanism is fixed in the variable diameter buffer mechanism, the air outlet end of the manual pressure regulating valve is connected with the air inlet end of a buffer pressure stabilizing tank through a flange, the air outlet end of the capacity-increasing air outlet pipeline is used for being connected with a elasticizer main network nozzle, and the nominal diameter of the capacity-increasing air outlet pipeline is DN80; the manual pressure regulating valve comprises a valve seat and a valve frame, wherein the valve frame is fixed on the valve seat, and a locking assembly is fixed on the top surface of a valve frame bottom plate; the reducing buffer mechanism comprises an inlet reducing section, a reducing buffer cavity and an outlet reducing section which are
