Abstract
The utility model discloses a three-way type rear plug, comprising a base and a plug on the base, a T-shaped three-way hole is arranged on the plug, a transverse hole is arranged along the radial direction of the plug, and a vertical hole penetrates through the base downwards. The three-way type rear plug is an integrated seal without a three-way flange and threaded screw connection, the three-way type rear plug can not be loosed and can not be popped up under high pressure, so as to effectively avoid equipment accidents and personal safety accidents; and the structure is simple, safe and reliable.
Description
Technical field
The utility model belongs to superhard material special equipment cubic apparatus synthesis press technical field, relates in particular to behind a kind of three way type stifled.
Background technology
Domestic whole equipment of film ultra-hard material synthesizer hinge type multiple pressure source cubic hinge press is made up of several parts such as main frame, pressure charging system, hydraulic system, electric control system and electric heater units.Main frame mainly is made up of six hinge beams, 12 pins, six working pistons and support and protector etc.Complete hinge beam equipment is stifled by working piston, hinge-beam jar body, back, threeway flange and sealing cylinder cap etc. are formed.During installation, be contained in working piston in the hinge beam, working piston is divided into work ante-chamber and work back cavity to the hinge-beam jar body.Hinge-beam jar body ante-chamber adopts big cylinder cap of cylindrical and the little cylinder cap fixing seal of interior circle, and a small rack is installed in middle part, hinge-beam jar body back cavity bottom, during work (backhaul) working piston withstand small rack be backhaul on earth.Being drilled with a circular hole in the cylinder base centre of hinge beam, mainly is to block up after a potted component-cylindrical shape is led to the heart in order to pass in and out hydraulic oil usefulness, in circular hole, to be equipped with, and stifled cylindrical mainly is a sealed hydraulic oil behind the logical heart, and leading to heart position is to pass in and out hydraulic oil.Back cavity hydraulic oil is lived with the threeway flange seal in the outside of the stifled sealing in back, is connected with tapering (tapering be placed on back block up seal the centre that leads to heart position and threeway flange) between the stifled sealing in back and the threeway flange.During synthetic work; Hydraulic oil gets into the cylinder body back cavity through the stifled sealing in back cavity oil pipe, threeway flange, tapering and back under the effect of booster pump; Promote piston-advance; The ante-chamber hydraulic cylinder is pressed fully at ante-chamber under the effect of valve and is set up high pressure, and the power that the graphite in the high-pressure chamber is accompanied by in the technical factor changes into diamond; When synthesis technique needs release to retreat after hours; Hydraulic oil directly gets into cylinder body ante-chamber promotion piston through the ante-chamber oil pipe and retreats under the effect of booster pump, back cavity hydraulic oil blocks up sealing, tapering, threeway flange and back cavity oil pipe along the back and gets back to fuel tank under thrust.
Fixed connection between the threeway flange blocks up with sealing is back only depends on four threaded screw to be connected.The reciprocation cycle work of high pressure and release is being born in the fixed connection of threaded screw.High load capacity reciprocation cycle work for a long time makes the fixed connection screw loosening easily.After the fixed connection screw was loosening, when being pressurized to the HTHP synthetic work once more, the threeway flange can be ejected by high pressure, causes high pressure moment off-load, and high-pressure chamber is blasted, and equipment is incurred loss; Serious is that the threeway flange that high pressure ejects down can injure personal safety as bullet.
The utility model content
The purpose of the utility model is blocked up after providing a kind of simple in structure, safe and reliable three way type.
For achieving the above object, the technical scheme that the utility model adopts is:
Stifled behind a kind of three way type, comprise the plug on base and the base, plug is provided with T type three through holes, and its cross-drilled hole radially is provided with along plug, and vertical core runs through base downwards.
Said cross-drilled hole two ends are equipped with flat bottomed recess.
Said vertical core axis overlaps with the plug axis.
Said cross-drilled hole is positioned at top-down 1/3rd places of plug.
The advantage that the utlity model has is:
1. the utility model is the integral type sealing, seals without the threeway flange, does not have threaded screw to connect, and can not become flexible, and can under high pressure not ejected, and has effectively avoided equipment breakdown and personal safety accident, and is safe and reliable;
2. the utility model blocks up and the threeway flange after substituting logical heart sealing fully, effectively reduces production cost;
3. the utility model is simple in structure, and reliability is high.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, stifled behind a kind of three way type, comprise the plug 6 on base 1 and the base 1, plug is provided with T type three through holes, and its cross-drilled hole 8 radially is provided with along plug 6, and vertical core 3 runs through base 1 downwards.Said cross-drilled hole 8 two ends are equipped with flat bottomed recess 4.Said vertical core 3 axis overlap with plug 6 axis.Said cross-drilled hole 8 is positioned at plug 6 top-down 1/3rd places.
In the utility model, cross-drilled hole 8 two ends one end is installed air relief cock 5 (when having gas to get in the cavity, can be used for exitting), another termination oil pipe 7, and cross-drilled hole 8 two ends are equipped with flat bottomed recess 4, help installing air relief cock and link oil pipe; Vertical core 3 is an oilhole; Plug lower end sidewall is provided with seal 2.
The operation principle of the utility model is: during synthetic work; Hydraulic oil is directly blocking up behind the entering three way type through back cavity oil pipe 7 under the effect of booster pump; Directly get into the cylinder body back cavity through oilhole stifled behind the three way type then; Promote piston-advance, the ante-chamber hydraulic cylinder is pressed fully at ante-chamber under the effect of valve and is set up high pressure, and the power that the graphite in the high-pressure chamber is accompanied by in the technical factor changes into diamond; When synthesis technique needs release to retreat after hours; Hydraulic oil directly gets into cylinder body ante-chamber promotion piston through the ante-chamber oil pipe and retreats under the effect of booster pump, back cavity hydraulic oil at the uniform velocity blocks up the direct back cavity oil pipe 7 that gets into and gets back to fuel tank behind three way type under the effect of balanced valve.
