Description
Technical field
The utility model is related to stress corrosion (cracking) test technical field, more particularly to a kind of high temperature and high pressure kettle sealing structure.
Background technology
High temperature and high pressure kettle provides the high-temperature high-pressure state of lasting stability for stress corrosion (cracking) test, simulates the actually used of sample
Environment, the accuracy for test provides sound assurance.In process of the test, the temperature of kettle is tested typically at 300 DEG C～600 DEG C,
Pressure 10MPa～30MPa in kettle.In order to realize the sealing of kettle cover and kettle, suitably using resistant to elevated temperatures metal sealing mode, such as
Becket conical surface seal.To reach preferable sealing effectiveness, the nut on kettle cover flange needs larger torque, so that sealing surface
It is brought into close contact.This just makes sealing contact surface generate micro deformation, along with process of the test, experiment kettle is integrally in high temperature
Under state, after off-test, experiment kettle is down to normal temperature, and in whole temperature changing process, metal produces effect of expanding with heat and contract with cold,
So that sealing contact surface firmly sticks together.Although this state is very beneficial for sealing, after off-test, contact surface cannot
Easy disengagement, it is impossible to take out sample, this causes certain impact on test.
In addition, kettle cover and kettle use bolt connection, if directly making to be tightened by bolts, after off-test, bolt and kettle
Threaded connection part adhesion phenomenon also occurs, it is just cumbersome during loose unloading bolt.
Due to there is presently no other significantly more efficient sealing means, to reach sealing effectiveness, the phenomenon of sealing surface adhesion
It is also less prone to eliminate.Method for kettle cover is opened after off-test, great majority are by the way of the physics strike such as percussion, vibrations.
Utility model content
In order to solve above-mentioned technical problem, the utility model provides a kind of high temperature and high pressure kettle sealing structure.
In order to achieve the above object, the technical scheme that the utility model is adopted is：
A kind of high temperature and high pressure kettle sealing structure, including kettle and the kettle cover that is connected with the kettle, the kettle upper end sets
Opening is equipped with, taper seat is provided with the opening, the kettle cover is provided with sealing ring, and the sealing ring is provided with and the taper seat
The arc surface of contact, is provided with screwed hole on the circumferencial direction of the kettle cover, and hexagon socket head cap screw, institute are provided with the screwed hole
State and be provided with counterbore away from described kettle one end on screwed hole.
As a kind of improvement of high temperature and high pressure kettle sealing structure described in the utility model, the kettle cover and the nut it
Between be provided with the packing ring being set on the screw rod.
As a kind of improvement of high temperature and high pressure kettle sealing structure described in the utility model, in the circumferencial direction of the kettle cover
On be uniformly provided with four screwed holes or two screwed holes.
As a kind of improvement of high temperature and high pressure kettle sealing structure described in the utility model, the sealing ring and the kettle cover
It is identical with the material of the kettle.
Used as a kind of improvement of high temperature and high pressure kettle sealing structure described in the utility model, the kettle is logical with the kettle cover
Cross screw rod to be fastenedly connected, fastened by nut positioned at one end of the kettle cover on the screw rod.
Advantageous Effects of the present utility model are：
By outputing several screwed holes on kettle cover, just kettle cover can be disengaged using hexagon socket head cap screw, will not to kettle cover or
Kettle causes any damage, and easily saves time, very convenient；
Kettle cover and kettle are connected using screw rod and nut, only nut need to be unscrewed into taking-up during dismounting, it is to avoid directly used
During bolt connection, the problem that bolt should not be removed with kettle；
The material of sealing ring is identical with the material of kettle cover and kettle, ensure that the close of high temperature and high pressure kettle at different temperatures
Envelope effect.

Specific embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Each embodiment of type is explained in detail.
Embodiment 1
As shown in Figure 1 and Figure 4, a kind of high temperature and high pressure kettle sealing structure, including kettle 1 and kettle cover 3, wherein, the upper end of kettle cover 3
Opening is provided with, kettle cover 3 is connected and closes the upper end open of kettle 1 with kettle 1.Four are uniformly provided with the circumferencial direction of kettle cover 3
Individual screwed hole, is provided with a hexagon socket head cap screw 2 on each screwed hole, due to kettle cover 3 it is thicker, away from kettle on each screwed hole
1 one end is provided with a counterbore, in order to the installation of hexagon socket head cap screw 2.After off-test, kettle cover 3 and kettle 1 are bonded together, only
Successively hexagon socket head cap screw 2 need to be tightened by diagonally opposed, just kettle cover 3 can slowly be ejected.
Embodiment 2
The present embodiment is further improved on the basis of embodiment 1, as depicted in figs. 1 and 2, the kettle of the present embodiment
The upper end of body 1 is provided with opening, and taper seat 8 is provided with opening, and kettle cover 3 is provided with sealing ring, and sealing ring is provided with and is connect with taper seat 8
Tactile arc surface 6, by the thrust between kettle cover 3 and kettle 1, between arc surface 6 and taper seat 8 conical surface seal is formed.Kettle
Body 1 is identical with the material of kettle cover 3, and its thermal coefficient of expansion is also identical, and reliable sealing effectiveness can be ensured at any temperature.
