Embodiment Construction

[0032] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0034] like Figure 1 to Figure 6 As shown, a kind of gas regulating valve provided by the present invention comprises:

[0035] The valve body 100 is provided with a first channel 110 along the axial direction of the valve body 100, and a second channel 120 is provided along the radial direction of...

Abstract

The invention provides a gas regulating valve, and belongs to the technical field of regulating valves. The gas regulating valve comprises a valve body, wherein a first channel and a second channel which are communicated with each other are respectively arranged along the axial direction and the radial direction of the valve body; a valve element, wherein the valve element is nested in the first channel, a third channel is formed in the axial direction of the valve element, and a first through hole and a second through hole which are communicated with the third channel are formed in the side wall of the valve element; a knob, wherein the knob is connected with the valve element, connection between the knob and the valve element is locked through a fastener, the valve element is driven by the knob to rotate, the first through hole and the second through hole are made to directly face and be staggered with the second channel one by one, and regulation of the gas flow is achieved. According to the gas regulating valve, the conventional circular through hole and the special-shaped through hole are formed in the valve element, gas flow regulation is realized under the action of the knob, and the regulation is set continuously and is free from a sudden change process, so that the gas flow regulation range is expanded.

Description

technical field [0001] The invention belongs to the technical field of regulating valves, and relates to a gas regulating valve. Background technique [0002] In the field of sewage treatment, the precise control of anoxic aeration and the control of the reflux ratio have been urgent problems to be solved for a long time. At present, UPVC ball valves are used, such as a new type of gas regulating valve disclosed in Chinese patent (CN202901350U). The regulating valve is to change the contact area between the bell-shaped opening and the two cavities of the valve seat by rotating the regulating rod. Although the gas regulating valve can realize on-off control and has a relatively long service life, the flow regulation range is small and the regulation accuracy is insufficient. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the existing technology, and propose a gas regulating valve capable of expanding the a...
