Description

Valve block structure of low noise

Technical Field

The utility model relates to a valve block structure of low noise belongs to fluid transmission technical field.

Background

The existing micropump has higher noise, particularly occasions with higher noise requirements, such as medical products. At present, the noise reduction mode is generally adopted for noise reduction, the whole pump is wrapped by a noise reduction material, although the noise reduction mode can also be used for noise reduction, the cost is higher, the heat dissipation of a motor is not facilitated, and the service life of a product is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art exists not enough, provides a valve block structure of low noise, can effective noise reduction, and the cost is lower, does not influence the motor heat dissipation.

In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a valve block structure of low noise, includes the valve body, be provided with the inlet end on the valve body and give vent to anger the end, all be provided with the valve lamellar body in the inlet end and the end of giving vent to anger, the structure of valve lamellar body: the valve block is located between the upper valve plate and the lower valve plate, a constraint groove is formed in the upper valve plate, a constraint step is formed in the lower valve plate, a crater structure is arranged between the two constraint grooves of the upper valve plate, a concave cavity is formed between the two constraint steps of the lower valve plate, the constraint step can be matched with the constraint groove, the crater structure can be matched with the concave cavity, the valve block is clamped and fixed through the constraint groove and the constraint step, and the valve block is driven to move towards the concave cavity through the crater structure.

The height of the restraint step is larger than the stroke of the valve plate, so that the far end of the stroke of the valve plate cannot touch the bottom of the concave cavity.

Compared with the prior art, the utility model beneficial effect who has is: the utility model discloses a injecing the stroke of valve block and reducing the area of contact of valve block and valve upper plate, reduced the noise of valve block, and the cost is lower, has avoided the problem of the traditional production of making an uproar of falling.

Detailed Description

As shown in fig. 1-4, the utility model relates to a valve block structure of low noise, including valve body 1, be provided with inlet end 3 and the end 4 of giving vent to anger on the valve body 1, all be provided with valve lamellar body 5 in inlet end 3 and the end 4 of giving vent to anger, valve lamellar body 5's structure: including valve upper plate 51, valve block 52 and valve hypoplastron 53, valve block 52 is located between valve upper plate 51 and the valve hypoplastron 53, be provided with restraint recess 54 on the valve upper plate 51, be provided with restraint step 55 on the valve hypoplastron 53, be provided with volcanic vent structure 56 between two restraint recesses 54 of valve upper plate 51, there is concave cavity 57 between two restraint steps 55 of valve hypoplastron 53, restraint step 55 can and restraint recess 54 phase-match, volcanic vent structure 56 can and concave cavity 57 phase-match, valve block 52 is fixed through restraint recess 54 and restraint step 55 centre gripping, and drives valve block 52 through volcanic vent structure 56 and moves to concave cavity 57.

The height of the restraining step 55 is larger than the stroke of the valve plate 52, so that the far end of the stroke of the valve plate 52 is ensured not to touch the bottom of the concave cavity 57.

The noise of the current diaphragm pump mainly consists of three aspects: 1. mechanical transmission noise (motor driving noise, bearing noise, etc.), 2. gas vibration noise; 3. the valve plate slaps the noise. Wherein the flap slapping noise is the main noise source. The utility model discloses a change the valve block structure, change the effect that the mode of slapping of valve block and valve plate played the low noise. When the valve plate of the common diaphragm pump works, the movement distance of the valve plate is large, the slapping contact surface is large (the action of a diving athlete in water can be imagined, and the principle of the action can be known probably), and two slappings can be generated up and down (one slapping is on a working surface, and the other slapping is on an invalid surface). And the utility model discloses by the motion mode of valve plate restraint valve block for the valve block is at the during operation, and movement distance is short, and the contact surface of slapping is little, and only once effectively slapping.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
