Embodiment Construction
[0017] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
[0018] As shown in the figure, a circular damper includes a valve body 1, a gland 2, a sealing ring 3, a damper plate 4, a bottom shaft 5, a handle shaft 6, a handle 7, a handle lever 8, a blocking plate 9, and a spring 10. , Locating pin 11, bearing pin 12, handle sleeve 13, track groove 14, nut 15, shaft end nut 16 and handle seat 17. The ring-shaped valve body 1 and the ring-shaped gland 2 are connected by six sets of evenly distributed bolts. The inner circle of the mating surface of the valve body 1 and the gland 2 is provided with a circular sealing ring groove, and the sealing ring groove is squeezed A sealing ring 3 is fixed by pressure, and the axial center of the inner hole of the sealing ring 3 is not in the same direction as the axis of the valve body 1, and part of the sealing ring 3 protrudes from the groove of the sealing ...

The invention relates to a circular air regulating door which comprises a circular valve body, a circular air regulating plate, a circular pressing cover, a handle shaft, a handle combining piece, a positioning device and a bottom shaft, wherein the valve body is connected with the pressing cover through more than two groups of bolts, a sealing ring groove is formed in the matching surface of the valve body and the pressing cover, a sealing ring is arranged inside the sealing ring groove, the handle shaft and the bottom shaft are respectively connected on radial circular holes on the two sides of the valve body in a penetrating manner and in a rotating state, and the air regulating plate is connected onto the head part of the handle shaft and the bottom shaft. The air regulating plate rotates around the axis of the handle shaft, when the rotation is stopped one-way, the sealing ring is pressed, and when the air regulating plate is opened in an opposite direction, the air regulating plate is away from the sealing ring. The tail part of the bottom shaft is limited along the axial direction through a plugging plate connected on the external side of the radial circular holes formed in the valve body, the handle shaft is limited along the axial direction through a nut and a handle seat on the external side of the valve body, the handle combining piece is connected on the handle shaft, the positioning device is connected onto the valve body in a rotatable and positioning state with the handle combining piece. Through the eccentric-structured design of the circular air regulating door, the rotating shaft of the air regulating plate and the center of the valve body are arranged eccentrically, and the good sealing effect is ensured during complete close.
Description
technical field [0001] The invention relates to the field of marine air conditioners, in particular to a circular damper. Background technique [0002] Due to the particularity of the ship's sea voyage, the requirements for sealing are high. The ventilation required inside the hull is mainly based on mechanical air supply and mechanical exhaust. The ship's ventilation system is relatively large, with many air outlets and scattered. The air volume required by each air outlet is different, so it is necessary to adjust the air volume of the air outlet. At present, there are several sealed dampers on the market. completely off. Contents of the invention [0003] In order to solve the above problems, the present invention provides a circular damper designed with an eccentric structure. The rotating shaft of the damper is set eccentrically with the center of the valve body to ensure better sealing performance when fully closed. Adjust the damper. [0004] The ...
