Abstract
The utility model relates to a kind of embedded type hydraulic plug, by plug body and O RunddichtringO two-part, formed, it is characterized in that: adopt O RunddichtringO reliable sealing, during installation, plug enters valve body surface completely, does not take unnecessary valve body surface space, adopt screw threads for fastening, can repeated removal install, being suitable on shutoff hydraulic valve block diameter 12mm in narrow installation space, with interior auxiliary hole, is a kind of low price, reusable, seal reliable novel hydraulic plug.
Description
Technical field
The utility model relates to a kind of embedded type hydraulic plug, is suitable on shutoff hydraulic valve block diameter 12mm in narrow installation space and, with interior auxiliary hole, is a kind of low price, easy to use, seals reliable small-sized hydraulic plug.
Background technique
At present, in Hydraulic Valve Block Design manufacture process, the little auxiliary hole that diameter is less than 10mm has three kinds of conventional method for blocking: the first is that in adopting, hexagonal hydraulic pressure plug carries out shutoff, its advantage is that hole processing is simple, and plug sealing is reliable, easily installing/dismounting, its shortcoming is that floor space is large, have compared with multiple entity and stay on valve surface, can reduce the level of integration of valve piece, increase valve block long-pending; The second is to adopt than the jackscrew of the large 3mm of auxiliary hole left and right to carry out shutoff, and its advantage is low price, and occupation of land space is minimum, and shortcoming is for Leakage prevention, when jackscrew is installed, need to smear screw threads for fastening sealer, is not easy dismounting; The third is to adopt the ball formula high pressure plug that rises, and its advantage is that to take up an area space little, and shortcoming is disposable plug, cannot change or reuse.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of embedded type hydraulic plug, adopt more fastening than the metric thread of the large 3mm of the auxiliary hole diameter that needs shutoff left and right, adopt the sealing of O RunddichtringO, plug enters valve body surface completely, do not take unnecessary valve body surface space, be applicable to block the narrow and small auxiliary hole in position.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of embedded type hydraulic plug, comprise plug body and O RunddichtringO, and it is characterized in that: described plug body is comprised of the metric thread M of front end and the cone of tail end; The metric thread M of front end can be M3X0.5 to the serial fine thread between M14X1.5, be applicable to the auxiliary hole that diameter is less than 12mm.
The roundlet bottom surface of described plug body tail end cone is identical with the root of the tooth circular diameter of front end metric thread M, 30 ° of cone two stringcourse angles, on the great circle bottom surface of cone, there is the interior hexagonal counterbore that 4mm is dark, when installation and removal plug, can insert hexagonal rod spanner, described tail end cone stringcourse point midway stays a rectangle groove, for mounting O-shaped seal ring.
Described O RunddichtringO is common nitrile butadiene rubber and viton seal ring, is applicable to common antiwear hydraulic oil.
The utility model compared with prior art has following useful effect: the utility model is a kind of embedded plug, does not have unnecessary entity to stay valve body surface, can not affect the installation of element around; Adopt the sealing of O RunddichtringO, good airproof performance, easily installing/dismounting, can reuse.
Accompanying drawing explanation
A kind of embedded type hydraulic stopper structure of Fig. 1 figure.
A kind of embedded type hydraulic plug of Fig. 2 scheme of installation.
Embodiment
Below in conjunction with accompanying drawing and specific implementation process, the utility model is elaborated.
Referring to Fig. 1, a kind of embedded type hydraulic plug, comprises plug body 1, O RunddichtringO 2 two-part.
Plug body 1 is comprised of the metric thread M of front end and the cone of tail end, the metric thread M of front end can be that M3X0.5 is to the serial fine thread between M14X1.5, the roundlet bottom surface of tail end cone is identical with the root of the tooth circular diameter of front end metric thread, 30 ° of cone two stringcourse angles, on the great circle bottom surface of cone, there is the interior hexagonal counterbore that 4mm is dark, when installation and removal plug, can insert hexagonal rod spanner, tail end cone stringcourse point midway stays a rectangle groove, for mounting O-shaped seal ring 2, inclined hole face laminating on the circular cone inclined-plane of plug body 1 and valve body 3 during installation, by 2 sealings of O RunddichtringO.
