Abstract

The invention relates to a self-closing sealing choke plug, which comprises a sealing choke plug, a connecting cylinder fixed by a round nut, with one end sleeved in the sealing choke plug, and a pressure sensor mounting groove arranged in the connecting cylinder, wherein the sealing choke plug is provided with a sealing choke plug screw thread connected with a high-pressure closed container; the connecting cylinder is provided with a connecting cylinder sealing inclined plane; and the sealing choke plug is provided with a sealing choke plug inclined plane by correspondingly contacting with the connecting cylinder sealing inclined plane. By adopting the self-closing sealing choke plug, the higher the pressure of the gas in the high-pressure closed container is, the closer the contact of the connecting cylinder sealing inclined plane and the sealing choke plug inclined plane is, and the sealing performance is better. The self-closing sealing choke plug is used on a closed container the volume of which is 700mL as traditionally rigidly sealed in a closed container the volume of which is 200ml, the normal detection of pressure can be ensured. The installation and the operation are more convenient and the time and labor are saved by adopting the self-closing sealing choke plug.

Description

A kind of self-closing sealing plug
Technical field
The present invention relates to a kind of self-closing sealing plug.
Background technique
What the sealing of closed pressure vessel was adopted at present is the rigidity linkage structure, have detected pressures with the sealing plug of sensor and pressurized container directly by seal with screwed joint, it is the rigidity sealing, its advantage is simple in structure, shortcoming is to need bigger strength in assembling and when unloading, and assembling and unloading are inconvenient, especially when the volume of closed pressure vessel and internal pressure are bigger, adopt this rigidity seal action reliably not guaranteed, cause danger easily.
Summary of the invention
It is big more that technical problem to be solved by this invention provides a kind of high-pressure closed vessel pressure, and seal action is good more, and fitting operation self-closing sealing plug eaily.
The present invention adopts following technological scheme:
The present invention includes the round nut that passes through that sealing plug, an end be sleeved in the sealing plug is fixedly coupled tube and is arranged on pressure transducer mounting groove in the connecting cylinder, described sealing plug is provided with the sealing plug screw thread that is connected with high-pressure closed vessel, connecting cylinder is provided with connecting cylinder sealing inclined-plane, and corresponding and connecting cylinder seals the inclined-plane sealing plug that contacts and is provided with the sealing plug inclined-plane.
Beneficial effect of the present invention: gas pressure is big more in high-pressure closed vessel, connecting cylinder sealing inclined-plane contacts tight more with the sealing plug inclined-plane, sealability is also just good more, the present invention use on the seal container of 700mL volume and traditional rigidity formula to be sealed on the seal container of 200mL volume use the same, can guarantee that pressure normally detects (uses and can not reliably be guaranteed and adopt traditional rigidity formula to be sealed on the seal container of 700mL volume, cause danger easily), adopt fitting operation of the present invention more convenient, time saving and energy saving.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 assembles schematic representation for the present invention;
Accompanying drawing 3 is for adopting the present invention at 0.24gcm -3Pressure-time plotted curve under the loading density in the seal container powder burning process of 700ml volume;

In the accompanying drawings: 1 connecting cylinder, 2 connecting cylinders sealing inclined-plane, 3 sealing plug inclined-planes, 4 pressure transducer mounting grooves, 5 round nuts, 6 sealing plugs, 7 sealing plug screw threads, 8 high-pressure closed vessels.
Embodiment
Accompanying drawing 1 is depicted as one embodiment of the present of invention, the present invention includes a sealing plug 6, connecting cylinder 1 and round nut 5.Sealing plug 6 is fixed on the high-pressure closed vessel 8 by sealing plug screw thread 7, pressure transducer is installed on the pressure transducer mounting groove 4 of connecting cylinder 1, the transfer wire of pressure transducer is drawn outside the high-pressure closed vessel 8 by sealing plug 6 one ends, and connecting cylinder 1 is fixing by round nut 5 and sealing plug 6.Corresponding with connecting cylinder sealing 2 positions, inclined-plane outside being arranged on connecting cylinder 1, sealing plug 6 is provided with sealing plug inclined-plane 3, connecting cylinder sealing inclined-plane 2 and sealing plug inclined-plane 3 contact, gas pressure is big more in high-pressure closed vessel 8, connecting cylinder sealing inclined-plane 2 contacts tight more with sealing plug inclined-plane 3, sealability is also just good more.Fitting operation of the present invention is more convenient, and more laborsaving, and pressure is big more, and seal action is good more.
Self-closing sealing plug of the present invention is used for the high-temperature gas pressure test that burning generates under the airtight condition, and gas pressure descends along with the reduction of temperature, so its sealability adopts comparative test to test.Under identical loading density (filling quality/seal container volume), gas pressure-time graph that test burning back generates, Fig. 3-Fig. 8 is respectively 0.24gcm -3, 0.20gcm -3And 0.12gcm -3The test result of the seal container (adopt existing rigidity formula sealing, see Fig. 4,6,8) of seal container of 700mL volume under the loading density (adopt self-closing sealing of the present invention, see Fig. 3,5,7) and 200mL volume relatively.Test result shows the present invention and traditional rigidity sealing means comparison, the present invention use on the seal container of 700mL volume and traditional rigidity formula to be sealed on the seal container of 200mL volume use the same, can guarantee that pressure normally detects (use and can not reliably be guaranteed and adopt traditional rigidity formula to be sealed on the seal container of 700mL volume, cause danger easily).
