Description

Pipeline butt joint structure for high-pressure-resistant three-valve group

Technical Field

The utility model relates to the field of valve body pipeline butt joint, in particular to a pipeline butt joint structure for a high-pressure-resistant three-valve group.

Background

The three valve groups are composed of three valves which are communicated with each other, and comprise two stop valves and a balance valve, wherein the left side of the common three valve groups on the market is a high-pressure valve, the right side of the common three valve groups is a low-pressure valve, and the top of the common three valve groups is a balance valve.

In the prior art, the working flow of the three valve bodies is as follows: when the tubing is fed with medium from an initial (empty) condition, the pressure across the sensor will suddenly change, which pressure differential may damage the sensor of the transmitter if it is too great. To avoid this, the valves A, B on both sides of the sensor should be closed first and the bypass valve C opened; after the medium fills the pipeline and approaches to stability and balance, one of A or B is opened, so that the pressure is uniformly applied to the two sides of the sensor; closing the valve C, opening the other valve A or B, and starting the normal operation of the sensor; the closing sequence is opposite to the situation, the common three-valve pipeline connection mode on the market is to directly sleeve the hose outside the pipeline arranged on the valve body, or sleeve the hose with similar size outside the pipeline arranged on the valve body after softening, or sleeve the hose outside the pipeline, and then add a pipe hoop outside the hose to prevent the hose from falling off from the pipeline.

However, when the pressure in the pipe is increased, the hose is easy to fall off, after the hose is sleeved outside the pipe after softening treatment, the hose is hardened due to the reduction of the temperature, the hose is easy to crack, the fixing effect is poor, and the pipe hoop is added outside the hose, so that the fixing effect is enhanced to a certain extent in comparison with the two modes, but the risk of falling off is also caused when the pressure in the pipe is suddenly increased.
