Upper and lower side forms the air inlet and gas outlet being connected with valve pocket respectively, forms on the valve body medial wall of outlet port
Reaming, the medial wall of reaming form screw thread, be provided with valve plate, form convex on the upper surface of valve plate in the valve pocket of the valve body
Platform, boss upper sleeve are fixed with the protective cover of tubbiness, and protective cover forms some small air inlet holes, described protective cover grafting valve body
Air inlet in, be fixed with sealing gasket on the valve plate of described boss surrounding, sealing gasket is pressed against on the upper bottom surface of valve body；
The lower surface of the valve plate forms lead column, lead column grafting on the supporting plate, if gripper shoe is formed doing
Pore, described gripper shoe are plugged in the reaming of valve body, and lock sleeve is bolted with reaming, and lock sleeve is pressed against under gripper shoe
On end face, the center of gripper shoe lower surface forms land, and one end of extension spring is fixed in land, the other end is fixed on fixed cover
On, fixed cover is fixed on the lower end of lead column, forms external screw thread, extension spring on the lateral wall of the land and fixed cover of gripper shoe
Two ends be screwed onto in land and fixed cover respectively, described land sleeve is in lead column；
Spacing block set is fixed with described gripper shoe upper surface, protective cover exposes the upper surface of valve body, spacing block set
Expose the length of valve body to the distance of valve plate lower surface less than protective cover in upper surface.
Described valve plate is disc, and the inner diameter of the diameter of valve plate less than valve body internal valve cavity, the outer wall of protective cover are straight
Footpath is equal to the diameter of air inlet.
The beneficial effects of the present invention is：
It by increased safeguard structure in inlet port on the basis of present hot water blowdown intake valve, and in valve inner
Structure has carried out corresponding modification, prevents the function of bulky grain debris blocking air inlet from having its blowdown intake valve.

Specific embodiment：
Embodiment：As shown in Fig. 1,2, a kind of improved blowdown intake valve of water heater structure, including valve body 1, in valve body 1 into
The valve pocket 11 of type cylinder, the upper and lower side of valve body 1 are formed the air inlet 12 and gas outlet 13 being connected with valve pocket 11 respectively, are leaned on
Reaming 14 is formed on 1 medial wall of valve body at nearly 13 end of gas outlet, the medial wall of reaming 14 forms screw thread, the valve body 1
Valve plate 2 is provided with valve pocket 11, boss 22 on the upper surface of valve plate 2, is formed, 22 upper sleeve of boss is fixed with the protective cover of tubbiness
8, protective cover 8 forms some small air inlet holes 81, in the air inlet 12 of described 8 grafting valve body 1 of protective cover, described boss 22
Sealing gasket 7 is fixed with the valve plate 2 of surrounding, sealing gasket 7 is pressed against on the upper bottom surface of valve body 1；
The lower surface of the valve plate 2 forms lead column 21, and lead column 21 is plugged in gripper shoe 3, and gripper shoe 3 is formed
Some ventholes 31, described gripper shoe 3 are plugged in the reaming 14 of valve body 1, are bolted with lock sleeve 4, lock sleeve 4 in reaming 14
It is pressed against on the lower surface of gripper shoe 3, the center of 3 lower surface of gripper shoe forms land 41, and one end of extension spring 5 is fixed on land
On 41, the other end be fixed on fixed cover 6, fixed cover 6 is fixed on the lower end of lead column 21.
Described valve plate 2 is disc, the inner diameter of the diameter of valve plate 2 less than 1 internal valve cavity 11 of valve body, protective cover 8
Outer diameter is equal to the diameter of air inlet 12.
Spacing block set 9 is fixed with described 3 upper surface of gripper shoe, protective cover 8 exposes the upper surface of valve body 1, limit convex
Expose the length of valve body 1 to the distance of 2 lower surface of valve plate less than protective cover 8 in the upper surface of block 9.
External screw thread, the two ends difference of extension spring 5 are formed on the lateral wall of the land 41 and fixed cover 6 of the gripper shoe 3
It is screwed onto in land 41 and fixed cover 6, described 41 sleeve of land is in lead column 21.
Operation principle：The present invention pass through on the basis of present hot water blowdown intake valve 12 end of air inlet increase protective cover 8,
By, during water heater blowdown apparatus waterproof blowdown, negative pressure being formed in water heater liner, drive valve plate 2 is moved down, so as under protective cover 8
It is mobile, so as to the small air inlet hole 81 of protective cover 8 of the outside air from the outside of valve body 1 is entered and thereby anti-in 1 valve pocket 11 of valve body
The small air inlet hole 81 of shield 8 is entered in water heater liner, and which is effectively prevented while persistently balancing shape negative pressure in water heater liner
The air inlet 12 that extraneous bulky grain debris block valve body 1 is stopped.
