Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, a kind of for the vacuum sampling valve on reactor, comprise the valve body being formed by the order of upper, middle and lower by riser 1, discharge nozzle 2 and feeding pipe 3, valve body is provided with the inner chamber of a up/down perforation, that is to say, the inner chamber of riser 1, discharge nozzle 2 and feeding pipe 3 is all communicated with.The lower end (namely feeding pipe 3) of valve body is provided with material taking mouth 31, and upper end (riser 1) is provided with and promotes mouth 11.The lower end (feeding pipe 3) of valve body is fixed on reactor outer wall, and material taking mouth stretches into reactor inner chamber.Body cavity is equiped with feeding lifting arm, and feeding lifting arm cylindrical is provided with transmission outside thread; Promote mouth 11 and be equiped with drive bush 5, drive bush endoporus is provided with transmission internal thread, matches with the transmission outside thread of feeding lifting arm; The side opening at valve body middle part (discharge nozzle 2) is provided with discharge port 21.
In the present embodiment, for the convenience of processing and installing, valve body is to be divided into riser 1, discharge nozzle 2 and 3 three parts of feeding pipe.
Those skilled in the art person is appreciated that above-mentioned valve body can be also one, or is divided into more parts, is interconnected, and can coordinates with feeding bar 7 and lift-bolt 4 as long as reach its inner chamber.
In the present embodiment, for the convenience of processing and installing, feeding lifting arm is not one, but by feeding bar 7 and lift-bolt 4, formed, both are fixed together by screw thread, feeding bar 7 under, lift-bolt 4 is upper, and lift-bolt 4 cylindricals are provided with motion thread.
Those skilled in the art person be appreciated that above-mentioned feeding lifting arm can be also one or be divided into more part composition, at this, do not limit.
On the cylindrical of feeding bar 7, offer hopper 71, for depositing the resin that enters material taking mouth 31 from reactor.
Those skilled in the art person is appreciated that the shape of above-mentioned material taking mouth 31 can be also circular hole or rectangular opening, at this, does not limit.
Motion thread type on drive bush 5 and lift-bolt 4 is trapezoidal thread.Trapezoidal thread is a kind of motion thread of extensive use, processes more conveniently, and intensity is higher, not easy to wear.
Those skilled in the art person is appreciated that above-mentioned motion thread type can be also square threaded form or buttress thread form, does not limit at this.
Those skilled in the art person be appreciated that if on valve body structure, be designed to sealing form, above-mentioned seal ring also can, but valve body structure more complicated, use seal ring be preferred mode.
On drive bush 5, be provided with and rotate handwheel 6, rotation can drive drive bush 5 to rotate (by key 51 transferring power) while rotating handwheel 6.Because drive bush 5 is connected by motion thread with lift-bolt 4, when drive bush 5 rotates, lift-bolt 4 can do the movement (because drive bush 5 is fixed on riser 1, cannot move, and lift-bolt 4 not being fixed) of rising or declining vertically.
