Redesign the blocking technological holes requirement that a High Pressure Sealing Gland to occupy little space solves super-pressure valve block, and existing high pressure
Under environment, transposition or sliding easily occur for the sealing ring being set on seal plug, are the main reason for causing high-pressure drain plug to fail.
Utility model content
The technical problems to be solved in the utility model: purpose of the utility model is to solve it is in the prior art not
Foot provides a kind of a kind of High Pressure Sealing Gland for making sealing ring fastening, not transposition.
The technical solution of the utility model includes: a kind of High Pressure Sealing Gland described in the utility model includes plug ontology, institute
Stating plug ontology includes outer end face and interior contact surface, and the plug ontology is equipped with seal groove below interior contact surface, described close
Sealing ring is equipped in sealing groove, plug body central position is equipped with the first groove, is equipped in first groove for squeezing
Plug ontology makes plug ontology and hydraulic valve block inner wall form the first sealing auxiliary block of interference fit.
Further, first sealing auxiliary block center is equipped with the second groove, and the is equipped in second groove
Two sealing auxiliary blocks.
Further, screw thread is equipped in second groove, second groove (is screw thread company with the second sealing auxiliary block
It connects.
Further, the second sealing auxiliary block is equipped with draft angle, and the draft angle is 0.5-2 °.
It further, further include the subring being set to outside hydraulic valve block tube wall.
Further, first groove floor and seal groove are in same level or lower than seal grooves.
The utility model compared with prior art the utility model has the advantages that due to plug body central position be equipped with the first groove,
The first sealing auxiliary block is equipped in first groove, the first sealing auxiliary block can be installed in hydraulic valve block in plug ontology
Afterwards, by squeezing plug ontology, plug ontology is realized and is expanded, increase the pressure between plug ontology and hydraulic valve block tube wall, it is right
Plug ontology plays fixed function, and hydraulic due to being equipped with the plug ontology of sealing ring when the first sealing auxiliary block is not added
Pressure is smaller between valve block tube wall, and there are gaps, therefore not will lead to sealing ring in installation process and transposition or sliding easily occurs；By
It is equipped with the second groove in the first sealing auxiliary block center, the second sealing auxiliary block is equipped in second groove, therefore, the
Two sealing auxiliary blocks can play the role of secondary fastening to the first sealing auxiliary block and plug ontology, and sealing effect is good；Described
It is equipped with screw thread in two grooves, solves the problems, such as that existing plug is difficult to dismantle, it, can be with accordingly after dismounting second seals auxiliary block
Equipment extracts the first sealing auxiliary block out of first groove, the plug ontology and hydraulic valve block after extracting the first sealing auxiliary block
Pressure reduces between tube wall, and the plug ontology made is easy to extract out of hydraulic valve block tube wall, solves prior art seal plug peace
The problem of taking out is difficult to after dress；It is additionally provided with the subring being set to outside hydraulic valve block tube wall, protection can be played to hydraulic valve block tube wall
Effect, prevents hydraulic valve block tube wall because pressure crosses Major disruptionL；First groove floor and seal groove be in same level or
Lower than seal groove.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In order to deepen the understanding of the utility model, below we will the utility model is described in further detail in conjunction with attached drawing,
The embodiment is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
The utility model a kind of embodiment of High Pressure Sealing Gland as shown in figure 1, including plug ontology 2, plug sheet
Body 2 includes outer end face 2-1 and interior contact surface 2-2, and plug ontology 2 is equipped with seal groove 21, seal groove below interior contact surface 2-2
Sealing ring 22 is equipped in 21,2 center of plug ontology is equipped with the first groove 23, and the first sealing auxiliary is equipped in the first groove 23
Block 3.
As specific embodiment of the present utility model, the first sealing 3 center of auxiliary block is equipped with the second groove 34, the
The second sealing auxiliary block 4 is equipped in two grooves 34；Screw thread, the second groove 34 and the second sealing auxiliary block are equipped in second groove 34
4 be threaded connection；Second sealing auxiliary block 4 is equipped with draft angle, and draft angle is 0.5-2 °；It further include subring 5, the first groove
23 bottom surfaces and seal groove 21 are in same level or lower than seal grooves 21.
Working principle of the utility model is: when in use, sealing ring 22 is placed in seal groove 21, by plug ontology 2
It is packed into hydraulic valve block 1, is inserted in subring 5 in 1 corresponding position of hydraulic valve block；First sealing auxiliary block 3 is embedded in the first groove
In 23, then the second sealing auxiliary block 4 is embedded in the second groove 34, completes the secondary fastening of seal plug.When needing to take out
When plug ontology 2, the second sealing auxiliary block 4 and the first sealing auxiliary block 3 are removed by step, can will then be reduced and hydraulic valve
The plug ontology 2 of pressure takes out between block 1.
The utility model has the characteristics that make the fastening of sealing ring 22, not transposition, since 2 center of plug ontology is equipped with the
One groove 23, the first groove 23 is interior equipped with the first sealing auxiliary block 3, and the first sealing auxiliary block 3 can be installed in plug ontology 2
After entering in hydraulic valve block 1, by squeezing plug ontology 2, plug ontology 2 is realized and is expanded, increase plug ontology 2 and hydraulic valve block
Pressure between 1 tube wall plays fixed function to plug ontology 2, and first be not added for the plug ontology 2 due to being equipped with sealing ring 22
When sealing auxiliary block 3, pressure is smaller between 1 tube wall of hydraulic valve block, and there are gaps, therefore not will lead to sealing in installation process
Transposition or sliding easily occur for circle 22；Since the first sealing 3 center of auxiliary block is equipped with the second groove 34, second groove 34
It is inside equipped with the second sealing auxiliary block 4, therefore, the second sealing auxiliary block 4 can play the first sealing auxiliary block 3 and plug ontology 2
The effect of secondary fastening, sealing effect are good；Screw thread is equipped in second groove 34, solve that existing plug is difficult to dismantle asks
First sealing auxiliary block 3 can be extracted out of first groove 23 with relevant device, be pulled out after dismounting second seals auxiliary block 4 by topic
Pressure reduces between 1 tube wall of plug ontology 2 and hydraulic valve block after the first sealing auxiliary block 3 out, and the plug ontology 2 made is easy to from liquid
It is extracted in 1 tube wall of pressure valve block；It is additionally provided with the subring 5 being set to outside 1 tube wall of hydraulic valve block, 1 tube wall of hydraulic valve block can be risen and be protected
Shield effect, prevents 1 tube wall of hydraulic valve block because pressure crosses Major disruptionL；First groove, 23 bottom surface and seal groove 21 are in same water
Plane is lower than seal groove 21.
Above-mentioned specific embodiment only illustrates the technical concept and structure feature of the utility model, it is therefore intended that allow ripe
