Description
Technical Field
The invention relates to the field of valves , in particular to a valve installation sealing device.
Background
The valve effectively enables the opening of the tubing and is an important part of the transfer apparatus.
In the valve and the pipe connection process, often carry out fastening connection through the flange on valve flange and the pipeline, nevertheless when liquid transmits in the pipeline, there is liquid pressure, and traditional seal assembly can't carry out high-efficient sealed to long-time the use causes sealed damage, makes liquid reveal, and its structure of some high-efficient seal assemblies is complicated, and the dismouting is inconvenient.
Disclosure of Invention
The invention provides an installation sealing device for valves , which has a simple structure, is convenient to install and disassemble, and efficiently realizes the sealing of installation.
To achieve the above purpose, the installation sealing device for the valve comprises an installation connecting pipe, a valve connecting pipe and a sealing assembly;
the outer side of the mounting connecting pipe is provided with an external thread;
the lower end of the connecting pipe of the valve is provided with a blind cavity, the blind cavity is provided with internal threads and is installed on the installation connecting pipe in a threaded manner;
the seal assembly includes a seal ring located within the blind cavity and between the mounting nipple and the valve nipple.
, a annular groove is arranged at the upper end of the mounting connecting pipe, a second annular groove corresponding to the annular groove is arranged at the upper end of the blind cavity, and a sealing ring is arranged between the annular groove and the second annular groove.
, a thread seal tape is arranged between the mounting connecting pipe and the valve connecting pipe in a threaded connection mode.
Compared with the prior art, this kind of valve installation sealing device sets up the sealing washer in ring channels, take over valve and take over threaded connection with the installation, when the blind chamber contact in installation takeover and the valve takeover, compress the sealing washer, realize sealing it, liquid at first carries out step through the sealing washer and seals, rethread threaded connection carries out the second portion, consequently, realize the sealed of valve installation.

FIG. 1 is an overall schematic view of the present invention;
in the figure, 11, a mounting connecting pipe, 12, an external thread, 13, th annular grooves, 21, a valve connecting pipe, 22, an internal thread, 23, second annular grooves, 24, a blind cavity, 3 and a sealing ring.
Detailed Description
The invention is further described with reference to the following figures.
As shown in fig. 1, the valve installation sealing device comprises an installation connecting pipe 11, a valve connecting pipe 21 and a sealing assembly;
the outer side of the mounting connecting pipe 11 is provided with an external thread 12;
the lower end of the connecting pipe 21 of the valve is provided with a blind cavity 24, the blind cavity 24 is provided with internal threads 22 and is installed on the mounting connecting pipe 11 in a threaded manner;
the sealing assembly comprises a sealing ring 3, the sealing ring 3 is positioned in the blind cavity 24 and is positioned between the installation connecting pipe 11 and the valve connecting pipe 21;
step , a -th annular groove 13 is formed in the upper end of the mounting connecting pipe 11, a second annular groove 23 corresponding to the -th annular groove 13 is formed in the upper end of the blind cavity 24, and the sealing ring 3 is arranged between the -th annular groove 13 and the second annular groove 23;
, a thread seal tape is arranged between the mounting connection pipe 11 and the valve connection pipe 21.
When the valve installation sealing device is used, firstly, the sealing ring 3 is arranged in the annular groove 13, the valve connecting pipe 21 is in threaded connection with the installation connecting pipe 11, when the installation connecting pipe 11 is in contact with the blind cavity 24 in the valve connecting pipe 21, the sealing ring 3 is compressed to realize sealing, namely, liquid is firstly sealed th through the sealing ring 3 and then sealed second through threaded connection, and therefore sealing of the valve installation is realized.
Claims (3)
