Problems solved by technology
[0003] When the ventilation plate controls the ventilation volume, it mainly relies on the rotation of the internal rotating plate to adjust the ventilation volume. However, the existing ventilation valve has a simple structure and poor sealing performance. For air leakage, sealing rings will be added to the outer circumference of some rotating plates to fill the gaps. However, after long-term use, the sealing rings are easily corroded and damaged by the exhaust gas inside the ventilation pipe, resulting in aging of the sealing rings and weakening the sealing of the ventilation valve. Reduced valve availability

Embodiment Construction
[0025] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0026] Such as figure 1 As shown, a ventilation valve with anti-aging function for exhaust gas discharge includes a pipe 1, a processor 2, a ventilation mechanism and two sealing mechanisms. The processor 2 is fixed on the outside of the pipe 1, and the processor 2 is equipped with a PLC, the ventilation mechanism and the sealing mechanism are both located inside the duct 1, and the ventilation mechanism is located between the two sealing mechanisms;
[0027] In the ventilation valve device, the exhaust gas is discharged to the outside through the pipe 1, and the ventilation mechanism facilitates air circulation. The sealing mechanism is used to seal from both sides of th...

The invention relates to a ventilation valve with an anti-aging function for waste gas emission. The ventilation valve involves a pipeline, a processor, a ventilation mechanism and two sealing mechanisms; the ventilation mechanism comprises a first motor, a rotating shaft, a rotating plate and fixing plates; and each sealing mechanism comprises a cylinder, a connecting rod, a moving frame, a direction adjusting assembly, a baffle, a sealing ring and a protecting assembly. According to the ventilation valve with the anti-aging function for waste gas emission, the rotating plate can be driven torotate through the first motor to control ventilation or sealing, when ventilation is carried out, the direction adjusting assembly drives the baffle to rotate to be parallel to lifting plates, the protection assemblies are used for isolating and protecting the sealing rings, when sealing is carried out, the adjusting assemblies drive the baffles to rotate to be parallel to the fixing plate, theair cylinders push the moving frame, so that the sealing rings are stuffed into a gap between the rotating plate and a through hole, the sealing performance is ensured, the contact between the sealingrings and the waste gas is reduced by utilizing the baffles, the aging speed of the sealing rings is delayed, and therefore, the practicability of equipment is improved.
Description
Technical field [0001] The invention relates to the field of ventilation equipment, in particular to a ventilation valve with anti-aging function for exhaust gas discharge. Background technique [0002] The ventilation valve is an invention for separating exhaust gas from the turbine in a turbocharged engine system. The separation of exhaust gas reduces the speed of the turbine and correspondingly reduces the speed of the compressor. The main function of the ventilation valve is to stabilize the propulsion pressure of the turbocharger system to protect the engine and turbocharger. [0003] When the ventilation plate controls the ventilation volume, it mainly relies on the rotation of the internal rotating plate to adjust the ventilation volume. However, the existing ventilation valve has a simple structure and poor sealing performance. When the sealing process is performed, there is a gap between the ventilation plate and the ventilation hole, resulting in If there is air leakage,...
