Abstract
The invention provides a high-pressure plug which comprises a hexagonal section (101), a threaded section (102) and a conical face section (103). The hexagonal section (101) is arranged at the outermost end of the high-pressure plug and comprises a hexagonal nut (101a) and a connecting part (101b). The connecting part (101b) is connected with the conical face section (103). The connecting part (101b) is a cylinder, and the diameter of the connecting part (101b) is smaller than that of the threaded section (102). When the high-pressure plug is in use, a conical face of the conical face section (103) is embedded in an installation hole and is in interference fit with the installation hole, so that a sealing function is achieved; the wide end face of the conical face section (103) is connected with the connecting part (101b), and the narrow end face of the conical face section (103) is connected with the threaded section (102); and the threaded section (102) is a cylinder provided with an external thread. The high-pressure plug is excellent in sealing effect, high in reliability, low in cost, simple in structure and easy to install and operate.
Description
Technical field
The invention belongs to the field of structural design of part, particularly to a kind of high-pressure drain plug.
Background technology
Sealing plug, at present in the shell part bearing high hydraulic coupling main adopt be plug screw band sealing gasket plug and ball rises formula plug.Plug screw band seals cushion plug and the ball formula plug that rises and is all made up of two parts.Plug screw band seals plug screw afterbody after cushion plug is installed and generally can be in outside mounting hole, overall dimensions is big compared with the ball formula plug that rises, and the seal form that plug screw formula is with sealing cushion plug is end face seal, seal under high pressures effect is undesirable and can not bear high pressure (more than 40MPa)；Ball rise formula plug install after overall dimensions little and can bear high pressure, but the technique of its component part and processing are more complicated, price is higher, and part needs to carry out heat treatment, needs special frock during installation.
Summary of the invention
It is an object of the invention to: solve ball in existing product and rise the shortcoming that formula High Pressure Sealing Gland structure is complicated, installation difficulty is bigger, relatively costly.
Technical solution of the present invention provides a kind of high-pressure drain plug, including six side's sections 101, thread segment 102 and conical surface section 103, described six side's sections 101 are in the outermost end of described high-pressure drain plug, it is connected with described conical surface section 103 including connecting portion 101b described in six square nut 101a and connecting portion 101b, described connecting portion 101b is cylinder and the diameter diameter less than described thread segment 102, during use, the conical surface of described conical surface section 103 embeds in installing hole, sealing function is played with described installing hole interference engagement, the wide end surface of described conical surface section 103 is connected with described connecting portion 101b, narrow end surface connects described thread segment 102, described thread segment 102 is cylinder band external screw thread.
Preferably, described six side's sections 101 are twisted into two parts after mounting.
The invention has the beneficial effects as follows: solve owing to plug quantity causes the problem that assembling is consuming time, cost is high of product more, it is proposed that one can bear elevated pressures, and sealing effectiveness is excellent, and reliability is high, and cost is low, and simple in construction installs high-pressure drain plug simple to operate.
Accompanying drawing explanation
Below accompanying drawing of the present invention is illustrated:
Fig. 1 is high-pressure drain plug；
Fig. 2 is schematic diagram after plug is installed.
Detailed description of the invention
High-pressure drain plug structure is shown in accompanying drawing 1, including six side's sections 101, thread segment 102 and conical surface section 103, described six side's sections 101 are in the outermost end of described high-pressure drain plug, it is connected with described conical surface section 103 including connecting portion 101b described in six square nut 101a and connecting portion 101b, described connecting portion 101b is cylinder and the diameter diameter less than described thread segment 102, the wide end surface of described conical surface section 103 is connected with described connecting portion 101b, narrow end surface connects described thread segment 102, and described thread segment 102 is cylinder band external screw thread.
After plug is installed, accompanying drawing 2 is shown in by schematic diagram, including high-pressure drain plug 1, installs housing 2, shell inner hole 3.By six square nut 101a of high-pressure drain plug six side's section 101 during installation, use torque spanner that high-pressure drain plug 1 is screwed into shell inner hole 3, thread segment 102 matches with the threaded portion of shell inner hole, high-pressure drain plug conical surface section 103 coordinates with the aperture place tapered portion of shell inner hole, it is screwed into the wide end surface junction until six side section 101b place cylinders with conical surface section 103 to rupture, till six side's sections 101 are twisted off completely.Shown in partial enlarged drawing E in accompanying drawing 2, high-pressure drain plug 103 place forms interference engagement with shell inner hole aperture contact position, is conducive to sealing.It addition, in order to strengthen sealing effectiveness and prevent thread looseness, when mounted, some thread locking adhesives need to be smeared on thread segment 102.
Claims (2)
1. a high-pressure drain plug, it is characterized in that, including six side's sections (101), thread segment (102) and conical surface section (103), described six side's sections (101) are in the outermost end of described high-pressure drain plug, it is connected with described conical surface section (3) including six square nuts (101a) and connecting portion (101b) described connecting portion (101b), described connecting portion (101b) is diameter less than described thread segment (102) of cylinder and diameter, during use, the conical surface of described conical surface section (103) embeds in installing hole, sealing function is played with described installing hole interference engagement, the wide end surface of described conical surface section (103) is connected with described connecting portion (101b), narrow end surface connects described thread segment (102), described thread segment (102) is cylinder band external screw thread.
