Background
A conventional hospital ventilation system adopts a constant-air-volume fan on a branch to ensure that the branch runs at constant air volume. Some of branch road constant air volume fans are equipped with the blast gate, and some are not equipped with the blast gate, but the blast gate only has switch function, can not be according to main line wind pressure condition automatic adjustment angle that opens and shuts. When the main pipeline wind pressure is too big, the main pipeline wind has a great influence on the branch fan, and the constant wind capacity function of the branch constant wind capacity fan cannot be really realized, so that the requirement of hospitals or other public health system places at home and abroad on the higher and higher air safety cannot be met. The constant air volume ventilator requires the main pipeline air pressure to be within a certain reasonable range in order to realize the constant air volume function.
SUMMERY OF THE UTILITY MODEL
Aiming at the working condition environment with strict air safety requirements, such as a ward and the like, an air valve capable of automatically adjusting the opening and closing angle according to the air pressure of a main pipeline is provided for a branch fan of a ventilation system, so that the constant air outlet volume of the branch fan is realized.
Therefore, the technical scheme adopted by the utility model is as follows: the utility model provides an electronic blast gate with angle modulation function, includes annular valve body of circle and circular shape valve block, the both ends of valve block are rotated respectively and are installed on the valve body, wherein one end of valve block stretches out outside the valve body and links to each other with the motor, motor fixed mounting is used for driving the valve block to rotate outside the valve body and realizes opening and shutting angle modulation, is provided with the boss at the circumference edge of valve block, is provided with the recess in the upper end inner wall circumference of valve body, and is equipped with the sealing washer in the recess, when motor drive valve block rotates and realizes closing, the boss of valve block and the recess laminating of valve body to combine the sealing washer to realize sealing.
Preferably, the bosses and the grooves are provided with a plurality of magnets in one-to-one correspondence at intervals, when the valve plate is closed, the bosses of the valve plate and the grooves of the valve body are tightly attracted through the magnets, and the magnets are additionally arranged for adsorption, so that the sealing performance of the valve plate when the valve plate is closed can be further ensured.
Further preferably, the lower end of the valve body is provided with an outward flange, and a plurality of mounting holes are formed in the outward flange at intervals, so that the mounting structure is simplified.
Further preferably, a motor mounting frame is arranged at the position, corresponding to the mounting position of the motor, of the outer side of the valve body, and the motor is fixed on the motor mounting frame through bolts.
Further preferably, the valve body can hover at any angle between 0-90 degrees, compared with 0 ℃ -
The 180 rotation is easier to control.
The utility model has the beneficial effects that: the electric air valve can electrically adjust the opening and closing angle, is applied to working conditions with strict requirements on air safety (such as wards and the like), particularly a branch ventilator of a ventilation system, and can realize the real constant air volume operation of the air volume of a branch where the fan is located by matching with a constant air volume fan on the branch; when the main pipeline air pressure of the ventilation system is larger, the electric air valve can be automatically closed by a small angle so as to resist the influence of the large air pressure of the main pipeline on the branch ventilator; and simple structure, design benefit, simple to operate, leakproofness are good.
