Above-mentioned novel switched stop valve, wherein also being provided with Gask-O-Seal in the junction of valve rod and bonnet.
The beneficial effects of the invention are as follows：It is of the invention under the long term of fluid media (medium) by using said structure,
Also the leakage of fluid media (medium) can be effectively prevented, so as to realize that sealing is blocked in reliable, stably fluid medium progress, this is protected significantly
The structural stability and performance of switch stop valve are demonstrate,proved.
Brief description of the drawings
The embodiment to the present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of novel switched stop valve.
In figure：Valve body 1, bonnet 2, handwheel 3, valve rod 4, water inlet 5, delivery port 6, valve member 7, cone 8, block 9 resets
Spring 10.
Embodiment
As shown in figure 1, a kind of novel switched stop valve, including valve body 1, bonnet 2 is provided with the top of valve body 1, in bonnet 2
On handwheel 3 and the valve rod 4 being connected with handwheel 3 are installed, be respectively equipped with water inlet in the left side central portion and lower right side of valve body 1
5 and delivery port 6, the valve member 7 of cylinder is connected with the bottom of valve rod 4, external screw thread is formed around in valve member 7, positioned at entering
The madial wall of valve body 1 between the mouth of a river 5 and delivery port 6 is provided with internal thread, and the internal thread of the external screw thread and valve body 1 of valve member 7
Between carry out screw thread cooperation, tip cone 8 directed downwardly is additionally provided with the bottom of valve member 7, the bottom in valve body 1 is additionally provided with gear
Block 9 and back-moving spring 10, block 9 are located at the lower section of valve member 7 and contacted with cone 8, left side and the back-moving spring 10 of block 9
One end is connected, and the other end of back-moving spring 10 is connected with valve body 1, and when valve member 7 is moved down, cone 8 drives block 9
Moved to the direction of delivery port 6 and block delivery port 6.
In real work, when handwheel 3 and valve rod 4 are at when outwarding winding state of upward position, valve member 7 and cone 8
The left side also being located in the position for leaving water inlet 5 and delivery port 6, block 9 in the presence of back-moving spring 10 in valve body 1（I.e.
Away from delivery port 6）, now fluid media (medium) just can be flowed into from the water inlet 5 of valve body 1, flow out, that is, realize from the delivery port 6 of valve body 1
The conducting state of switch stop valve；When rotation hand wheel 3 and valve rod 4 move down it, valve member 7 and cone 8 are also therewith
Start to move down, screw thread cooperation is now proceeded by between the internal thread of the external screw thread of valve member 7 and valve body 1, valve member 7 is realized
To the first resealing of valve body 1.At the same time, moving down with cone 8, cone 8 contacts and drives block 9 to valve
Right side movement in body 1（I.e. progressively close to delivery port 6）, and as valve member 7 and the continuous of cone 8 move down, block 9 is just final
Move at delivery port 6 and block delivery port 6, the second resealing to valve body 1 is realized by block 9, therefore, pass through above-mentioned knot
Structure, just realizes the dual-seal to water inlet 5 and delivery port 6 in valve body 1, so as to ensure that the close of switch stop valve significantly
Seal effect.
For above-mentioned novel switched stop valve, wherein being provided with screw thread valve opening on bonnet 2, external screw thread is provided with valve rod 4,
To be threadedly coupled between valve rod 4 and the screw thread valve opening of bonnet 2, in addition, in the madial wall of the valve body 1 at the position of delivery port 6
