Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-2, in this utility model embodiment, a kind of manual straight through adjustable throttle valve, including valve body 1, spool 5,
Valve seat 3 and valve gap 11, described valve body 1 is internal fluid feeding cavity 24, fluid issuing chamber 25 and spool chamber 26, and fluid enters
Oral cavity 24 connects at grade and all with spool chamber 26 with fluid issuing chamber 25, the fluid feeding cavity 24 being arranged such
Make choke valve installation at high pressure line and manifold link position fixing more accurate and convenient with fluid issuing chamber 25,
Described spool 5 is positioned at spool chamber 26 and valve gap 11 is internal, and spool 5 is the shaft-like structure that an end toper other end has screw hole,
Spool 5 top is provided with screw thread, and valve seat 3 and gland 6 are arranged respectively at bottom spool chamber 26 and top, and gland 6 is placed in spool chamber
Between 26 and spool 5, gland 6 is built-in with O RunddichtringO 7, circlip 8, Packing seat 9 and valve stem packing 10, pressure
