Embodiment:

Referring to Fig. 1～2, the concealed discharge valve of the utility model mainly is made up of limit plug 1, valve body 2, valve 3, movable spool 4, spring 5, valve rod 6 and

seal ring

7,8.

Described limit plug 1 is made up of stay tube 11 in coaxial and outer sleeve 12 and end-plate 13,

Interior stay tube 11 front ends extend forward and protrude from outer sleeve 11 front ends and form closed end, interior stay tube 11 rear end opening, stay tube 11 and outer sleeve 12 rear ends in end-plate 13 radially is covered in the form of a ring, axially offer a plurality of liquid entering holes 131 on the end-plate 13, this liquid entering hole 131 is connected with toroidal cavity between interior stay tube 11 outer walls and outer sleeve 12 inwalls, outer sleeve 12 front ends are uncovered, radially are provided with annular convex shoulder 121 on outer sleeve 12 internal faces, as Fig. 3.

Described valve body 2 radially is provided with circular orientation groove 21 on its outer wall, this circular orientation groove 21 matches with annular convex shoulder 121 on outer sleeve 12 internal faces; Axially spaced-apart is furnished with many spacing raised lines 22 on valve body 2 internal faces, form axially directed groove 23 between the adjacent spacing raised line 22, a segment distance is left from valve body 2 trailing edges in spacing raised line 22 rear ends, form radially restraining groove 24, this radially restraining groove 24 link to each other with axially directed groove 23 on valve body 2 internal faces, radially protrusion is provided with many spacing stops 25 on the restraining groove 24, as shown in Figure 7.

Described movable spool 4, axially offer a plurality of gap 41 on the shell wall of its rear end, and radially be provided with retaining convex rib 42 on its rear end outer wall of not open and clear mouthful, this radially retaining convex rib 42 match with the radially restraining groove 24 of valve body 2 internal face rear ends, be equipped with seal ring 7 on movable spool 4 outer wall, as Fig. 4.

As Fig. 5, movable spool 4 inserts its inner chamber by valve body 2 front ends, and the radially retaining convex rib 42 on the outer wall of its rear end matches with radially restraining groove 24 on the valve body 2 rear end internal faces.The outer sleeve 12 of limit plug 1 is placed on forward on the valve body 2 rear end outer wall, interior stay tube 11 front end insertion activity spools 4 inner chambers of limit plug 1; Valve rod 6 is by movable spool 4 front end insertion activity spools 4 inner chambers, and spring 5 is placed on the valve rod 6, and valve 3 is connected in valve rod 6 rear ends, as Fig. 6.Be equipped with seal ring 8 on the valve rod 6 front end outer wall, as Fig. 1.
