Hydraulic door closer
The invention discloses a hydraulic door closer which comprises a throttling valve rod, a piston cylinder body and a piston arranged in the cylinder body. The throttle valve rod is arranged on the upper section of the piston cylinder body, one part of the throttle valve rod is arranged in the cylinder body, and a shifting wheel is arranged on the throttle valve rod; a throttle valve gland and a throttle valve seat are sequentially arranged at the top end of the cylinder body, the throttle valve gland is fixed on the cylinder body, and the throttle valve seat is fixed on the throttle valve rod; a hemispherical groove is formed in the lower end of the throttle valve gland, and a hemispherical convex face matched with the hemispherical groove is arranged at the top end of the throttle valve seat. A one-way valve body is pressed into the piston, and a throttling hole is formed in the one-way valve body. The hydraulic oil can be continuously increased or decreased progressively, linear adjustment of the hydraulic oil is effectively improved, the viscosity of the hydraulic oil changes in different regions and seasons, and the using stability of the door closer is improved.
本发明公开了一种液压式闭门器，包括：节流阀杆、活塞缸体和设置在缸体内的活塞；节流阀杆装设在活塞缸体上段，一部分置于缸体内，该节流阀杆上设有拨轮；所述的缸体顶端依次设有节流阀压盖和节流阀座，节流阀压盖固定在缸体上，节流阀座固定在所述的节流阀杆上；所述的节流阀压盖下端设有半球形凹槽，所述的节流阀座顶端设有与所述的半球形凹槽相适应的半球形凸面；所述的活塞上面压入有单向阀体，单向阀体上面设有节流孔。本发明可以连续递增或者连续递减而，有效的提高液压油的线性调节，在不同地域、季节变化时，液压油粘稠度变化，提高闭门器的使用平稳性。
