Abstract
The utility model relates to a simple wind power control valve pipe, which comprises a pipe body, a valve plate and a positioning sleeve, wherein one end of the pipe body is a wind port end, and the other end is a connecting end; the inner wall of the tube body is circular, the valve plate is circular corresponding to the inner wall of the tube body, and the valve plate is rotatably arranged on the inner side of the air port end through rotating shafts symmetrically arranged on the edge of the valve plate; the pivot of valve plate extends to the lateral wall outside of body, the position sleeve elasticity hoop cover is on the body, and the constant head tank has been seted up to the nearly wind gap end one side border symmetry of position sleeve, and the position sleeve makes under the elastic force the pivot of valve plate is held to the constant head tank card. The utility model discloses thereby can adjust the wind-force in the valve plate adjustment pipeline fast to under the arbitrary aperture of valve plate, the position sleeve can all carry out better location to the valve plate, avoids the valve plate to make the aperture change gradually because the vibration of wind-force.
Description
Technical Field
The utility model relates to a simple and easy wind control valve pipe.
Background
The air valve is an indispensable central air-conditioning end fitting in ventilation, air conditioning and air purification projects of industrial factory buildings and civil buildings, is generally used in air conditioners and ventilation system pipelines, is used for adjusting the air quantity of branch pipes, and can also be used for mixing and adjusting fresh air and return air. The existing air valve basically adopts an automatic valve connected with a controller, but under a few conditions of air pipe maintenance and the like, the air pipe needs to be subjected to quick and direct wind power cut-off operation in a non-shutdown state, and although the prior art can accurately control wind power, the prior art is inconvenient in operation.
Disclosure of Invention
An object of the utility model is to provide a concatenate simple and easy wind control valve pipe in air pipe specifically realizes by following technical scheme:
a simple wind power control valve pipe comprises a pipe body, a valve plate and a positioning sleeve, wherein one end of the pipe body is an air port end, and the other end of the pipe body is a connecting end; the inner wall of the tube body is circular, the valve plate is circular corresponding to the inner wall of the tube body, and the valve plate is rotatably arranged on the inner side of the air port end through rotating shafts symmetrically arranged on the edge of the valve plate; the pivot of valve plate extends to the lateral wall outside of body, the position sleeve elasticity hoop cover is on the body, and the constant head tank has been seted up to the nearly wind gap end one side border symmetry of position sleeve, and the position sleeve makes under the elastic force the pivot of valve plate is held to the constant head tank card.
The simple wind power control valve pipe is further designed in that an annular groove located on the inner side of the positioning sleeve is formed in the middle of the outer wall of the pipe body, a limiting piece capable of longitudinally sliding in the annular groove is arranged on the inner wall of the positioning sleeve, and the limiting piece is elastically connected with the groove wall of the annular groove through a spring, so that the positioning sleeve is elastically hooped on the pipe body.
The simple wind power control valve pipe is further designed in that a friction gasket for increasing resistance is arranged in the positioning groove.
The simple wind power control valve pipe is further designed in that a knob is connected to the end of a rotating shaft of the valve plate.
The utility model has the advantages that:
the utility model discloses thereby can adjust the wind-force in the valve plate adjustment pipeline fast to under the arbitrary aperture of valve plate, the position sleeve can all carry out better location to the valve plate, avoids the valve plate to make the aperture change gradually because the vibration of wind-force.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic view of the structure of the positioning sleeve.
Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
the simple wind power control valve pipe comprises a pipe body 1, a valve plate 2 and a positioning sleeve 3, wherein one end of the pipe body is an air port end 12, and the other end of the pipe body is a connecting end 13; the inner wall of the tube body is circular, the valve plate is circular corresponding to the inner wall of the tube body, and the valve plate is rotatably arranged on the inner side of the air port end through rotating shafts 21 symmetrically arranged on the edge of the valve plate; the pivot of valve plate extends to the lateral wall outside of body, the position sleeve elasticity hoop cover is on the body, and the constant head tank 31 has been seted up to the nearly wind gap end one side border symmetry of position sleeve 3, and the position sleeve makes under the elasticity the pivot of valve plate is held to the constant head tank card.
The embodiment can thereby adjust the wind-force in the valve plate adjustment pipeline fast to under the arbitrary aperture of valve plate, the position sleeve can all carry out better location to the valve plate, avoids the valve plate to make the aperture change because of the vibration of wind-force.
The middle part of the outer wall of the pipe body 1 is provided with an annular groove 11 positioned at the inner side of the positioning sleeve, the inner wall of the positioning sleeve 3 is provided with a limiting sheet 32 which can longitudinally slide in the annular groove, and the limiting sheet is elastically connected with the groove wall of the annular groove through a spring 4, so that the positioning sleeve is elastically hooped on the pipe body.
The locating slot has a friction pad 33 therein for increasing the resistance. The end of the valve plate's shaft is connected with a knob 22 that facilitates the adjustment of the valve plate's operation.
