Novel throttle valve device on door closer
The invention provides a novel throttle valve device on a door closer, relates to the technical field of door closers, and aims to solve the problem that linear adjustment of door closing time cannot be achieved due to the fact that an existing door closer is affected by viscosity change of hydraulic oil. The throttle valve is arranged at the top of the piston cylinder and further comprises a throttle valve gland, a throttle valve seat, a throttle valve sleeve and a throttle valve rod, the throttle valve seat is installed on the piston cylinder through the throttle valve gland, the throttle valve rod is meshed with the throttle valve seat through threads, and the throttle valve sleeve is sleeved with the throttle valve rod. The throttle valve device is adopted, and when the viscosity of hydraulic oil changes due to large temperature changes in winter and summer, the gap between the throttle valve rod and the one-way valve body can be linearly increased or decreased through adjustment of the throttle valve device.
本发明提供了一种闭门器上的新型节流阀装置，涉及闭门器技术领域，旨在解决现有的闭门器受液压油粘稠度变化的影响，导致关门时间不能实现线性调节的问题，采用的技术方案是，包括节流阀和活塞缸，所述节流阀设在所述活塞缸的顶部，所述节流阀还包括节流阀压盖、节流阀座、节流阀套和节流阀杆，所述节流阀座通过所述节流阀压盖安装在所述活塞缸上，所述节流阀座上通过螺纹啮合有所述节流阀杆，所述节流阀杆上还套设有所述节流阀套，采用节流阀装置，在冬夏季节因温度变化较大引起液压油粘稠度变化时，可以通过这种节流阀装置的调节，让节流阀杆与单项阀体之间的间隙线性地变大或者变小。
