Abstract
The utility model discloses a needle valve provided with a two-piece valve rod. The needle valve comprises a valve seat, an upper valve rod, a lower valve rod and a valve core, wherein the upper valve rod and the lower valve rod are fixedly arranged in the valve seat, a T-shaped ring groove is arranged on the bottom of the upper valve rod, a lug boss matched with the T-shaped ring groove is arranged at the top of the lower valve rod, and the lower valve rod is suspended on the bottom of the upper valve rod through the lug boss and the T-shaped ring groove; and the valve core is fixedly arranged on the bottom of the lower valve rod. According to the utility model, the length of the single valve rod is reduced, the processing precision is easily ensured, a riveting process is reduced, the working efficiency is improved, and the needle valve has the advantages of good stability and reliable seal.
Description
Technical field
The utility model relates to a kind of needle type valve, in particular, relates to a kind of needle type valve with two-piece type valve rod
Background technique
Needle type valve is a kind of valve that can accurate adjustment, is widely used at oil, chemical system instrument pneumatic pipeline, in measuring pipeline, and be important component part in the instrument measurement pipe-line system, its function is to open or the cutting out pipeline path.
Conventional needle value as shown in Figure 1, comprise valve rod 1, valve seat 4 and existing spool 5, described valve rod 1 is arranged at described valve seat 4 inside, and between described valve rod 1 upper half part and described valve seat 4, filler bolt 2 is set, and between described valve rod 1 middle and lower part and described valve seat 4, filler 3 is set; Described existing spool 5 is a cone, and described existing spool 5 is riveted on described valve rod 1 bottom.
Existing needle type valve valve rod 1 is elongated, is difficult for guaranteeing machining accuracy, and spool is less, is riveted on the spool bore of valve rod end, and stability is bad.
The model utility content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provide a kind of simple in structure, processing density is meticulous and the needle type valve with two-piece type valve rod of good stability.
In order to solve above technical problem, the utility model provides a kind of needle type valve with two-piece type valve rod, comprise valve seat, upper valve rod, lower valve rod and spool, it is inner that described upper valve rod and described lower valve rod are fixedly installed on described valve seat, described upper valve rod bottom arranges T-shaped annular groove, described lower valve rod top arranges a boss that is used in conjunction with described T-shaped annular groove, and described lower valve rod is mounted on the bottom of described upper valve rod by described boss and described T-shaped annular groove; Described spool is fixedly installed on the bottom of described lower valve rod.
The technological scheme that the utility model further limits is: described spool and described lower valve rod are one-body molded.
Further, described spool is cone.
Further, also comprise the filler bolt, described filler bolt is arranged between described upper valve rod and described valve seat.
Further, also comprise filler, described filler is arranged between described lower valve rod and described valve seat.
The beneficial effects of the utility model are: the needle type valve with two-piece type valve rod described in the utility model, and the structure of use upper valve rod and lower valve rod reduces single shaft length, and machining accuracy is convenient to guarantee; Upper valve rod and lower valve rod articulate, and have reduced riveting step, increase work efficiency; Lower valve rod and spool are one-body molded, good stability, and centring property is good, and sealing is reliable.

Embodiment
Embodiment 1
A kind of needle type valve with two-piece type valve rod that the present embodiment provides, its structural representation comprise valve seat 4, upper valve rod 6, lower valve rod 7 and spool 8 as shown in Figure 2.
Valve seat 4 is for the structure of a hollow, upper valve rod 6 and lower valve rod 7 are fixedly installed on valve seat 4 inside, and, between upper valve rod 6 and valve seat 4 inwalls, filler bolt 2 is set, between lower valve rod 7 and valve seat 4 inwalls, condiment 3 is set, compared with prior art, upper valve rod 6 deducts the sealing position of filler 3, and machining accuracy easily guarantees.
As shown in Figure 3, upper valve rod 6 bottoms arrange T-shaped annular groove 9, and lower valve rod 7 tops arrange a boss 10 that is used in conjunction with T-shaped annular groove 9, and lower valve rod 7 is mounted on the bottom of upper valve rod 6 by boss 10 and T-shaped annular groove 9.The structure that this articulates, easy to use, reduced the operation of riveting, improved working efficiency.
Spool 8 is the very thin cone in bottom, and its top is fixedly installed on the bottom of lower valve rod 7.In the present embodiment, spool 8 is one-body molded with lower valve rod 7, good stability, and sealability is reliable.
When the needle type valve with two-piece type valve rod described in the utility model is assembled, lower valve rod 7 is mounted on upper valve rod 6, and upper valve rod 6 and lower valve rod 7 are arranged at valve seat 4 inside, between upper valve rod 6 and valve seat 4 inwalls, filler bolt 2 is set, after between lower valve rod 7 and valve seat 4 inwalls, condiment 3 being set, assembling is completed.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
