Specific embodiment
As shown in Figures 1 to 3
This stop valve includes valve seat 1, valve gap 2, valve rod 4, seal membrane 3.
The chamber 11 of upper end open is provided with valve seat 1, and 11 bottom chamber wall of chamber is extended with intercepting block to upper end open direction
12, and intercepting block 12 extends to the front and rear sides cavity wall of chamber 11, and chamber 11 is separated into left and right two cavitys, intercepting block
12 upper surfaces are distance with 11 upper end open of chamber, and the upper surface width of intercepting block 12 is less than the width of 12 bottom of intercepting block
Degree, the side wall of intercepting block 12 is one section of smooth skew wall；
1 arranged on left and right sides of valve seat each extends over the inlet tube 13 and outlet 14 communicated with chamber 11, inlet tube 13 and goes out
Mouth pipe 14 is respectively at 12 both sides of intercepting block, and there are 45 ° of bendings, the end of outlet 14 in 13 top of inlet tube to 1 downside direction of valve seat
Holding to 1 upside direction of valve seat has 45 ° of bendings, bending angle and outlet 14 of 13 top of inlet tube to 1 downside direction of valve seat
End is identical to the bending angle in 1 upside direction of valve seat, from 13 top of inlet tube of valve seat 1, inlet tube 13, chamber 11, outlet
The end of pipe 14 and outlet 14 is constituted for medium through transfer passage.
Between 1 bottom of the side wall of intercepting block 12 and valve seat, institute's angle degree is less than or equal to 13 top of inlet tube to valve seat 1
The bending angle in downside direction.
Valve gap 2 is located at the upper end open of chamber 11, and valve gap 2 is bolted on valve seat 1, and seal membrane 3 is arranged
Between valve gap 2 and valve seat 1, seal membrane 3 is completely covered on 1 upper end open of valve seat, and 3 upper surface of seal membrane is provided with limit convex
Platform, valve gap 2 is provided with through thereon, the screwed hole of lower surface, and valve rod 4 runs through the screwed hole of valve gap 2 from top to bottom, in the middle part of valve rod 4
The screw thread coordinated with 2 screwed hole of valve gap is provided with, 4 upper end of valve rod is stretched out outside valve gap 2, and 4 upper end of valve rod is fixed with handwheel 5, under valve rod 4
End is provided with contact block 6, and 6 top of contact block is provided with the draw-in groove of the draw-in groove 61 coordinated with 4 lower end of valve rod, 4 lower end of valve rod and contact block 6
61 coordinate and fix, and 6 lower end of contact block is provided with the limited impression coordinated with the positive stop lug boss of seal membrane 3, seal membrane 3 spacing
Boss is filled in the limited impression of contact block 6, makes to connect between contact block 6 and seal membrane 3.
When this stop valve is installed, the end at the top and the port of export of inlet tube 13 respectively with medicine machining production line two
Horizontal pipe 7 is connected, and 13 top of inlet tube is connected with the horizontal pipe 7 of side, as 13 top of inlet tube is under valve seat 1
Side to there is 45 ° of bendings, so the setting angle of this stop valve horizontal by the transfer passage in 45 ° of angles, i.e. valve seat 1 with
There are 45 ° of inclination angles between horizontal plane, but because the end of outlet 14 there are 45 ° of bendings to 1 upside direction of valve seat, then make 14 end of outlet
End can be connected with opposite side horizontal pipe 7, the horizontal level of the horizontal level of inlet tube 13 higher than outlet 14, this cut-off
Although the horizontal pipe 7 of valve both sides is also to maintain level after mounting, require both when pipeline 7 is arranged with regard to preset height
Difference.
Handwheel 5 is rotated, 4 relative valve gap 2 of valve rod is moved up, and seal membrane 3 is separated with intercepting block 12, flows into transfer passage
Medium can be between seal membrane 3 and intercepting block 12 gap flowing.
When needing for this stop valve to send out unlatching, handwheel 5 is rotated backward, 4 relative valve gap 2 of valve rod is moved down, seal membrane 3
Progressively contact with intercepting block 12, until seal membrane 3 is resisted against 12 upper end of intercepting block completely, make chamber 11 be separated into left and right two
Individual separate cavity.
When after production empty pipeline 7, this stop valve is opened, due to the setting angle and horizontal plane of this stop valve
It is in that the medium remained in 45 °, this stop valve can flow under self gravitation effect, the medium of residual firstly flows through inlet tube 13, so
Side wall along intercepting block 12 flow to outlet 14 afterwards, and then flows out outside this stop valve, it is to avoid medium is remained in this stop valve.
Above-described is only a kind of embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of without departing from this utility model principle, some modifications and improvement can also be made, these also should be regarded as
Belong to protection domain of the present utility model.
