Description

Integral blast gate

The technical field is as follows:

the utility model belongs to the field of fresh air conditioners, and relates to an integral air valve.

The background art comprises the following steps:

at present, all can use the blast gate in the new fan, including the air inlet valve, the return air valve, circulation blast gate etc. the blast gate that has again generally includes wind gap flange, valve body and blast gate, and the motor, above-mentioned part are the components of a whole that can function independently structure, installs one by one during the equipment on the casing of new fan, its shortcoming lies in:

1. the structure is complex and the installation is complex.

2. And the existing air valve is driven by a motor to rotate around the inner cavity of the valve body, and a sealing and limiting device is not arranged between the air valve and the inner cavity of the valve body, so that the sealing property is poor.

3. The motor is directly fixed on the valve body and is exposed outside, and a waterproof structure is not arranged, so that the motor is easy to damage and the service life of the motor is influenced.

4. The outer end of the valve body is directly connected with the pipeline, and the installation is not firm.

The utility model has the following contents:

aiming at the defects in the prior art, the utility model provides an integral air valve which adopts an integral modularized integral structure and is directly installed on a fan, so that the cost is saved, the integral structure is firmer, more stable and convenient to install, the air valve cannot be clamped in the operation process, and the quality problem is reduced.

In order to achieve the purpose, the technical scheme of the utility model is as follows:

an integral air valve comprises an integral structure module consisting of a valve body, a stepping motor and an air valve; the valve body comprises a base and a valve cavity, the air valve is installed in the valve cavity and rotates clockwise or anticlockwise around the valve cavity, the stepping motor is installed above the valve cavity and is matched with the air valve to drive the air valve to rotate, and a limiting stop is arranged at a position, matched with the air valve, in the valve cavity to play a role in sealing and limit the air valve to rotate 90 degrees clockwise or anticlockwise.

Furthermore, the stepping motor is arranged on the valve cavity through a positioning installation groove designed on the valve cavity, and a cover plate is arranged on the stepping motor.

Furthermore, the two semicircular staggered structures ensure that the air valve can be positioned in a sealing manner when rotating clockwise and anticlockwise by 90 degrees.

Furthermore, the outer edge of the front end of the valve cavity is divided into four parts around the whole circle to design buckle bulges.

Compared with the prior art, the utility model has the advantages that the tuyere flange and the air valve in the prior art are designed into a whole, so that the cost is saved, the integral structure is firmer, stable and convenient to install. The functions of opening and closing the air valve are realized through forward and backward rotation of the stepping motor, the stepping motor is installed on the valve body through a positioning installation groove designed on the valve cavity and fixed by self-tapping screws, and a cover plate is arranged on the motor to ensure that the stepping motor cannot be damaged. The limiting stop is designed in the valve cavity, and the two semicircular staggered structures are designed, so that the air valve can play a role in positioning when rotating clockwise and anticlockwise for 90 degrees, the air valve cannot be clamped in the operation process to reduce the quality problem, and certain sealing performance can be ensured. The buckle bulges arranged on the valve cavity are designed to be divided into four parts around the whole circle, so that the positioning function is realized in the use of the connecting pipeline, the installation is convenient, and the falling-off is not easy.
