The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of manual air volume control valve, and it is intended to solve volume damper of the prior art and regulates the technical problem that blade loss is serious, adjustment knob is difficult to twisting.
For achieving the above object, the utility model provides a kind of manual air volume control valve, comprise valve housing in a tubular form, it is located at the adjustment blade of valve housing inside and it is located at the adjustment knob of valve housing outside, described adjustment knob is connected with adjustment blade, the described side of adjustment blade leans mutually with the inwall of valve housing, it is characterized in that: also comprise function unit, described function unit comprises rotation axis, spring piece and blast bag, described rotation axis is through the central authorities regulating blade, the center line of blade overlaps the axis of described rotation axis with regulating, and with the axis perpendicular of valve housing, one end of described spring piece is fixedly connected with the side of blade with regulating, the other end is connected with the bag mouth of blast bag, the bag mouth of described blast bag is located near rotation axis, described blast bag is fixedly connected with adjustment blade.
As preferably, described adjustment knob is fixedly connected with rotation axis, described adjustment knob drives and regulates blade to rotate to vertical direction by horizontal direction.
As preferably, described spring piece and blast bag are all located at and are regulated one side leeward on blade.
As preferably, described adjustment knob is also provided with adjustment hole and adjusting bolt, and the inwall of described adjustment hole is provided with the screw thread matched with adjusting bolt, described adjustment knob is fixedly connected with valve housing by adjusting bolt.
As preferably, being also provided with air quantity graduated scale in the outside of described adjustment knob.
The beneficial effects of the utility model: compared with prior art, a kind of manual air volume control valve that the utility model provides, rational in infrastructure, adopt the spring piece and blast bag that are mutually permanently connected, make to regulate blade except opening and closing valve, the air quantity flowing through control valve can also be adjusted, thus greatly strengthen the result of use of control valve, and, the blast bag being located at leeward side can reduce the vibrations regulating blade edge, extend the work-ing life regulating blade, simultaneously, when wind speed in control valve is bigger, blast bag can also provide reverse turning force, so that user is more laborsaving when rotating outside adjustment knob.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the first embodiment of the present utility model;
Fig. 2 is the schematic top plan view of the first embodiment of the present utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by accompanying drawing and embodiment, the utility model being further elaborated. It should be understood that specific embodiment described herein is only in order to explain the utility model, it is not limited to scope of the present utility model. In addition, in the following description, eliminate the description to known features and technology, unnecessarily obscure concept of the present utility model to avoid.
Consult Fig. 1 and Fig. 2, embodiment of the present utility model provides a kind of manual air volume control valve, comprise valve housing 1 in a tubular form, it is located at the adjustment blade 2 of valve housing 1 inside and it is located at the adjustment knob 3 of valve housing 1 outside, described adjustment knob 3 is connected with adjustment blade 2, the side of described adjustment blade 2 leans mutually with the inwall of valve housing 1, also comprise function unit, described function unit comprises rotation axis 41, spring piece 42 and blast bag 43, described rotation axis 41 is through the central authorities regulating blade 2, the center line of blade 2 overlaps the axis of described rotation axis 41 with regulating, and with the axis perpendicular of valve housing 1, one end of described spring piece 42 is fixedly connected with the side of blade 2 with regulating, the other end is connected with the bag mouth of blast bag 43, the bag mouth of described blast bag 43 is located near rotation axis 41, described blast bag 43 is fixedly connected with adjustment blade 2.
A kind of manual air volume control valve that the utility model provides, rational in infrastructure, adopt the spring piece 42 and blast bag 43 that are mutually permanently connected, make to regulate blade 2 except opening and closing valve, the air quantity flowing through control valve can also be adjusted, thus greatly strengthen the result of use of control valve, and, the blast bag 43 being located at leeward side can reduce the vibrations regulating blade 2 edge, extend the work-ing life regulating blade 2, simultaneously, when wind speed in control valve is bigger, blast bag 43 can also provide reverse turning force, so that user is more laborsaving when rotating outside adjustment knob 3.
Specifically, described adjustment knob 3 is fixedly connected with rotation axis 41, and described adjustment knob 3 drives and regulates blade 2 to rotate to vertical direction by horizontal direction.
