On the lower face of support plate, the center of support plate lower face forms land, and one end of tension spring is fixed in land, the other end
It is fixed on fixing sleeve, fixing sleeve is fixed on the lower end of lead, is molded on the land of support plate and the lateral wall of fixing sleeve
There is external screw thread, the both ends of tension spring are screwed onto in land and fixing sleeve respectively, and the land sleeve is on lead.
Further it is improved to, the strainer is three layers, is followed successively by first filter layer, high efficiency filter layer, active carbon layer from outside to inside.
Further it is improved to, the high efficiency filter layer is H13 filter layers.
Further it is improved to, spacing block set is fixed with the support plate upper surface, protective cover exposes the upper end of valve body
Face, the distance of upper surface to the valve plate lower face of spacing block set are less than the length that protective cover exposes valve body.
Further it is improved to, the valve plate is disc, and the diameter of valve plate is less than the inner diameter of valve body internal valve cavity, prevents
The outer diameter of shield is equal to the diameter of air inlet.
The beneficial effects of the invention are as follows：
1st, intake valve provided by the invention, due to strainer, and strainer is layer strainer, so as to big in air inlet
Grain, molecule are effectively filtered, and purify air inlet.
2nd, intake valve provided by the invention, it is anti-by being added on the basis of present hot water blowdown intake valve in inlet port
Protection structure, and corresponding modification has been carried out in valve inner structure, prevent bulky grain debris from blocking up from having its blowdown intake valve
Fill in the function of gas port.
