The working principle of the invention and process are as follows:
Closed state: as shown in Figure 1, swingle 17a is pulled up along the first vertical slot 611 into the first translot 612,
And be maintained at swingle 17a in the first translot 612 along the rotation of the first translot 612, then drive of the pull rod 7 in swingle 17a
Under move up, and then drive left scraper 9a and right scraper 9b to turn to vertical position by left connecting rod 8a and right connecting rod 8b, this
When left scraper 9a and right scraper 9b be fully located in the first mounting groove 63；Under the active force of the first spring 15, valve rod 6 is in most
Upper end position, the upper surface of extension diameter section 62 and the lower end surface of flap 2 offset, and the lower end surface of extension diameter section 62 and closure spool 3
Upper surface offsets, and makes to block the opening of spool 3 backstop hole 105.Can be manually rotated second handle 13 drives pivoted housing 14 to rotate, and then makes valve
Valve 2 is moved down into its lower end surface and the upper surface of valve seat 103 and offsets, and through flow hole 104 is blocked, inlet channel 101 and go out
Mouth runner 102 separates obstructed.
Open state: as shown in Figure 9, Figure 10, firstly, pulling down first handle 16, make first handle 16 with ovable valve stem 6
Overcome the active force of the first spring 15 to move down, then adjusts swingle 17a into the second translot 613 downwards, then pull rod 7
It is moved down under the drive of swingle 17a, and then left scraper 9a and right scraper 9b is driven by left connecting rod 8a and right connecting rod 8b
Extending radially out to outside the first mounting groove 63 along valve rod 6 is turned to by the vertical position of Fig. 1, and snaps into the bottom surface in backstop hole 105
On, closure spool 3 is headed on by the lower end surface of valve rod 6 at this time moves down, and then can be manually rotated second handle 13 and drives pivoted housing 14
Rotation, and then move up flap 2 to open through flow hole 104, inlet channel 101 is connected to outlet flow 102.
Strike off adhering medium state: as shown in Fig. 4-Fig. 8, firstly, position can be manually rotated second handle 13 as shown in Figure 1
Flap 2 is set to be moved upwards up to certain position, then under the active force of the first spring 15, valve rod 6 is also and then moved up, and then makes
It blocks spool 3 and moves up closing backstop hole 105, partition inlet channel 101 is connected to outlet flow 102, then will rotation
Bar 17a is adjusted downwards into the second translot 613, then pull rod 7 moves down under the drive of swingle 17a, and then passes through left company
Bar 8a and right connecting rod 8b drives left scraper 9a and right scraper 9b to turn to extending radially out along valve rod 6 by the vertical position of Fig. 1
Outside first mounting groove 63, the lower end surface of the upper knife edge and flap 2 of left scraper 9a and right scraper 9b has been contacted at this time, is then adjusted
Second handle 13 makes flap 2 be moved down into the lower blade of left scraper 9a and right scraper 9b and the upper end face contact of valve seat 103, so
Rotation first handle 16 drives left scraper 9a and right scraper 9b to make rotating motion in turn afterwards, lower end surface and valve seat 103 to flap 2
Upper surface adherency medium struck off.After having struck off, then adjusting second handle 13 moves up flap 2, then will rotation
Bar 17a is readjusted into the first translot 612, then left scraper 9a and right scraper 9b turn to vertical position again, then rotates
Two handles 13 move down flap 2 to be re-closing off through flow hole 104, just complete the work for entirely striking off adhering medium.
