Technical Field
The utility model belongs to the medicine production field, concretely relates to scalable amount of wind test cover of formula is inhaled to magnetism for carry out the amount of wind test of clean district high efficiency air outlet.
Background
The clean air quantity and the ventilation times of the clean area in the medicine production industry are required, and the air quantity of each high-efficiency air outlet in the clean area can be regularly tested in the daily production process. The existing air volume meter consists of an air volume testing device and an air volume testing cover, wherein the height of the air volume testing device is 0.1m, the height of the air volume testing cover is 0.8m, the combined height is 0.9m, and the average height of an air port between functions in a clean area is 3 m. When the air quantity is tested, the air quantity instrument is lifted to the height of the air opening through the movable lifting frame under the general condition; or the air volume testing cover is aligned to the high-efficiency air outlet in a mode of manually lifting the air volume meter, and the test is carried out. In addition, the sizes of the air inlet areas in the rooms of the clean area are different, and during air quantity testing, the air quantity testing cover with a proper size is required to be replaced frequently according to the air inlet areas.
However, the conventional air flow meter has the following problems: 1. a minimum of two people is required to perform the operation. 2. If the lifting frame is used for assisting in testing, the lifting frame needs to be adjusted in height every time a room is transferred (the clean area of a medicine production enterprise is generally small and many), so that the operation is inconvenient; and a manual lifting mode is used, so that personnel are tired and the satisfaction degree of the personnel is low when long-time operation is carried out. 3. The air volume test cover is of a fixed size, the disassembly and assembly operations are difficult, and the efficiency is low.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to solve the defects of the prior art, the utility model provides a scalable amount of wind test cover of formula is inhaled to magnetism.
The technical scheme is as follows: the wind volume test cover comprises a wind volume test cover body, wherein the wind volume test cover body is of a trapezoidal structure with a wide upper part and a narrow lower part, and the bottom of the wind volume test cover body is fixedly arranged on a wind volume instrument;
arc grooves are respectively formed in four corners of the front side of the frame at the top of the air volume test cover body, and strong magnet pieces are correspondingly installed in the arc grooves;
the frame at the top of the air volume test cover body is a pipe which is sleeved with the inside and the outside, and can be used for adjusting the length of the frame, specifically, a plurality of small holes are drilled on the side surface of each pipe, the length of the pipe is adjusted according to the size of an air outlet during testing, so that the size of the whole frame at the top of the air volume test cover body is adjusted, the size of an opening of the air volume test cover body is matched with the size of the air outlet, a wedge is inserted into the small holes and is fixed by a nut, and air ports which can be matched with various sizes and specifications are obtained without replacing the air volume test cover.
As an optimization: the number of the arc grooves is 8, and the arc grooves are evenly distributed on four corners of the front surface of the frame at the top of the air volume test cover body.
As an optimization: the depth of the arc groove is 1 mm.
As an optimization: the thickness of the strong magnet piece is 1 mm.
As an optimization: the frame material of amount of wind test cover body be stainless steel.
As an optimization: the interval between adjacent small holes is 1 cm.
Has the advantages that: the utility model reduces the operators and the cost; the pollution caused by the movement of people in a clean area can be effectively reduced, and the quality of products is ensured; the air volume test cover with other sizes and specifications is saved; the operation difficulty of the equipment is reduced, and the satisfaction degree of the staff is improved.
