Problems solved by technology

[0005] At this time, when the installation space is limited, if the pipe connected to the Venturi valve is an elbow, the connecting rod protruding from the valve body will easily touch the side wall of the elbow, and it will be difficult for the Venturi valve to perform normal opening and closing operations. There is room for improvement

Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0041] Example:

[0042] see figure 1 and figure 2 , a Venturi valve, comprising a valve body 1 and a valve cone 2 arranged in the valve body 1 . The valve body 1 is in a cylindrical shape, the diameter of the middle portion of the valve body 1 is slightly smaller than the diameters of both sides in the axial direction, and an opening and closing passage 11 is formed in the middle portion of the valve body 1 . Both sides of the valve body 1 along its axial direction can be detachably fixed with a support frame 3, and a valve stem 4 is detachably and fixedly connected between the two support frames 3, and the axis of the valve stem 4 is collinear with the axial direction of the valve body 1 . The valve cone 2 is coaxially fixed with a sliding sleeve 21 , and the valv...

Abstract

The invention discloses a Venturi valve and relates to the technical field of Venturi valves. The Venturi valve comprises a valve body and a valve cone arranged in the valve body, wherein a support frame is fixedly arranged on one side in the axial direction of the valve body, a valve rod is fixedly arranged on the support frame, the axial direction of the valve rod is parallel to the axial direction of the valve body, and the valve rod penetrates through the valve cone and is in sliding fit with the valve cone along the axial direction of the valve rod; an adjusting rod penetrates through theside wall of one axial side of the valve body, the middle of the adjusting rod is rotationally arranged at the position where the adjusting rod penetrates through the side wall of the valve body, anda hinged rod is arranged between one end, in the valve body, of the adjusting rod and the valve cone; a driving part used for driving the adjusting rod to rotate is arranged on the outer side of thevalve body; and a sealing assembly is arranged at the rotary joint of the adjusting rod and the valve body. The Venturi valve has the advantages that the valve rod can be prevented from being pushed out of the valve body, the applicability of the Venturi valve to installation in different installation spaces is improved, and normal opening and closing operation of the Venturi valve can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of Venturi valves, in particular to a Venturi valve. Background technique [0002] A Venturi valve is a valve manufactured using the principle of the Venturi effect, that is, a Venturi airflow control valve, which can extend airflow control to the highest level. [0003] The existing utility model authorized notification number is the Chinese patent CN207893146U, which discloses a Venturi valve. The Venturi valve includes a valve body. A connecting rod is arranged in the valve body. A first stopper and a second stopper are set, a spool is arranged between the first stopper and the second stopper, the spool can pass through the first stopper, and at least two magnets are arranged between the first stopper and the spool , the same magnetic poles of two adjacent magnets are arranged facing each other. A supporting structure is provided at the end of the connecting rod, and the supporting structure includes a ...
