Or away from the fluid intake, the internal diameter with diameter greater than the fluid intake of the valve element.
The valve rod is provided with groove above valve element, is provided with first seal, the valve seat correspondence described first in groove
The position of sealing member is provided with boss.
For trapezoidal, the first seal and the one side that the boss coordinates are inclined-plane, institute in the first seal section
Boss section is stated for taper.
The valve rod stage casing is provided with lobe, and the lobe is fitted with valve base inner wall, and it is close that the lobe is provided with second
Seal, position of second sealing ring between valve gap and sample connection, second sealing ring are close with the valve base inner wall
Envelope coordinates, and the height of second sealing ring is higher than sample connection.
The rotary handle is in flower pattern.
The rotary handle is threaded connection with valve rod.
The beneficial effects of the utility model are as follows：Made by the rotation handle actuatable valve bar opposite valve seat motion described

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, this utility model can be better described.
A kind of sampling valve, including valve seat 1, and valve seat 1 coordinate valve element 3, the valve rod 2 for driving valve element 3, be located at valve seat
Black box between 1 and valve rod 2 or valve element 3, the valve seat 1 are provided with fluid intake 101, sample connection 102, the valve seat
Valve gap 4 is threadedly coupled on 1, and the valve rod 2 is threadedly coupled through valve gap 4 with valve gap 4, and the valve rod 2 is set through the outer end of valve gap 4
There is rotary handle 201, make the valve element 3 close by rotating the 201 actuatable valve bar of rotary handle, 2 opposite valve seat, 1 motion
Or away from the fluid intake 101, the internal diameter with diameter greater than the fluid intake 101 of the valve element 3.By rotating the rotation
Changing hands the motion of handle actuatable valve bar opposite valve seat makes the valve element closer or far from the fluid intake, realizes closure or openness,
Valve seat is threadedly coupled with valve gap, can realize that valve gap and valve rod are installed and dismounting by rotary valve cover, convenient that internal structure is examined
Repair, clean and change parts.
The valve rod 2 is provided with groove above valve element 3, is provided with first seal 5 in groove, and the correspondence of the valve seat 1 is described
The position of first seal 5 is provided with boss 103.First seal is coordinated with boss, realizes sealing, prevents liquid from letting out in closure
Dew.
5 section of the first seal is trapezoidal, and the one side that the first seal 5 is coordinated with the boss 103 is oblique
Face, 103 section of the boss are taper.First seal realizes sealing, sealing with boss in the way of inclined-plane with cone point cooperation
Effect is more preferable.
2 stage casing of the valve rod is provided with lobe 202, and the lobe 202 is fitted with 1 inwall of valve seat, the lobe 202
It is provided with the second sealing ring 6, position of second sealing ring 6 between valve gap 4 and sample connection 102, second sealing ring 6
Coordinate with 1 inner wall sealing of the valve seat, the height of second sealing ring 6 is higher than sample connection 102.Prevent sampling valve from opening
When, gap leakage of the liquid between valve rod and valve gap and valve gap and valve body goes out, and one is to cause to waste, and two is the handss of operator
