Detailed Description
The present invention will be further described with reference to the following detailed description of preferred embodiments thereof, which is to be read in connection with the accompanying drawings.
First, will be described with reference to fig. 1-5 according to the utility model discloses a valve block for diaphragm pump for the diaphragm pump, its application scene is very wide.
As shown in FIGS. 1-5, the utility model discloses a valve block for diaphragm pump has: valve frame 1, isolation beam 2, inlet valve core 3 and play gas valve core 4.
Specifically, as shown in fig. 1 and 3, the isolation beam 2 is located in the valve frame 1, the isolation beam 2 divides the valve frame 1 into a pair of valve core areas 12 which are not communicated with each other, and the inlet spool 3 and the outlet spool 4 are respectively arranged in the pair of valve core areas 12.
Specifically, as shown in fig. 1 and 3, the surface area of the inlet and outlet spools 3 and 4 is less than the surface area of the core region 12. Wherein, the two opposite sides of the air inlet valve core 3 are integrated with the boundary of the valve core area 12, and the other two opposite sides respectively have a gap with the boundary of the valve core area 12; the two opposite sides of the air outlet valve core 4 are integrated with the boundary of the valve core area 12 where the air outlet valve core is located, and gaps are respectively arranged between the two opposite sides and the boundary of the valve core area 12 where the air outlet valve core is located.
Further, as shown in fig. 2 and 4, the other opposite two sides of the air inlet valve core 3 are provided with air inlet arc-shaped edge strips 31 extending outwards along the surface of the air inlet valve core 3; the other two opposite sides of the air outlet valve core are provided with air outlet arc-shaped edge strips 41 which extend outwards along the surface of the air outlet valve core; the arc strake 31 of admitting air and the arc strake 41 of giving vent to anger have the clearance with the border of place valve core district 12 respectively, furthermore, because the region and the size of valve core district 12 are fixed, therefore, do not change the size in aforementioned clearance, the width that will admit air case 3 and go out valve core 4 narrows down, reserve the space of arc strake, not only can ensure that the arc strake can seal the gas inlet and the gas outlet of diaphragm pump completely, and can ensure that the consumption of diaphragm pump reduces moreover, and improve the vibration frequency of case, noise reduction.
