Problems solved by technology

[0002] Existing vane-type throttle valves generally include a plurality of flat blades, and the switching angle of the throttle valve is adjusted by changing the inclination angle of the blades by rotating the blades. However, as the size of the throttle valve increases, only by rotating the blades Adjusting the angle of the throttle valve switch cannot accurately control the flow of fluid, especially for vacuum coating equipment, the larger the throttle valve is, the more waste of gas will be caused, and the more difficult it is to control the vacuum degree in the equipment

Embodiment Construction

[0014] Such as figure 1 As shown, a vane throttle valve according to a preferred embodiment of the present invention includes a casing 10 , a plurality of vanes 30 and a plurality of baffles 50 disposed in the casing 10 .

[0015] The number of blades 30 can be changed according to needs. In this embodiment, only five blades 30 are shown for simplicity of illustration. The blades 30 are evenly spaced and connected as a whole by a connecting piece 70. The connecting piece 70 includes a lengthwise connecting rod 72 and several connecting pieces 74 rotatably connected to the connecting rod 72. The connecting pieces 74 The quantity is set according to the number of blades 30 , and each connecting piece 74 is connected to the upper surface of a blade 30 , and the way of connecting the connecting piece 74 and the blade 30 can be sticking, welding and the like.

[0016] Each blade 30 is in the shape of a thin plate, and the blade 30 is provided with a plurality of through holes 32 p...

Abstract

The invention relates to a vane type throttle valve comprising a plurality of vanes, each vane is provided with at least one through hole and slidably connected with a baffle plate; and the baffle plates are provided with penetrating holes which correspond to the through holes positioned on the vanes. The baffle plates can slide relative to the vanes to regulate the opening degree of the through holes positioned on the vanes so as to accurately control the flow rate of fluids passing through the vane type throttle valve, therefore the fluids are saved.

Description

technical field [0001] The invention relates to a vane throttle valve. Background technique [0002] Existing vane-type throttle valves generally include a plurality of flat blades, and the switching angle of the throttle valve is adjusted by changing the inclination angle of the blades by rotating the blades. However, as the size of the throttle valve increases, only by rotating the blades Adjusting the angle of the throttle valve switch cannot accurately control the flow of fluid, especially for vacuum coating equipment, the larger the throttle valve size, the more waste of gas will be caused, and the more difficult it is to control the vacuum degree in the equipment. Contents of the invention [0003] In view of this, it is necessary to provide a vane throttle valve capable of precisely controlling the switching angle. [0004] A vane type throttle valve, comprising several vanes, each vane is provided with at least one through hole, each vane is slidably connected wit...
