Description
Technical field
This utility model relates to machinery valve technology, particularly relates to a kind of low temperature valve detecting and leaking outside.
Background technology
Generally, pipeline valve at the construction field (site) is installed and used and is required for before examining its sealing
Survey, accomplish that " zero " leaks, because if leakage phenomenon in use occurs, the most again change
Valve is the most comparatively laborious, keeps in repair the most relatively difficult, it usually needs spend more human and material resources.Valve
The main Types of leakage is divided into and leaking outside and internal hemorrhage due to trauma, and the safe operation to valve that leaks outside produces significant impact, easily
Causing the serious accident of burst, some fire explosion, intoxication accident are all caused by valve leakage out of steam system.Low
Temperature valve rod sealing station district is mainly made up of upper valve body, valve rod, black box etc., and this structure is difficult to
In use examinations leaks outside, thus it is difficult to ensure that the effectiveness of valve stem seal, causes whole deck valve
The safety and reliability of door is had a greatly reduced quality.
Utility model content
This utility model aims to provide a kind of low temperature valve detecting and leaking outside, it is ensured that Subzero valve valve stem seal
Performance can detect, prevent and improve Subzero valve security and the reliability.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:
A kind of detect the low temperature valve leaked outside, including upper valve body, valve rod and main sealing assembly, also include close
Packing ring and plug component, described upper valve body inner surface is provided with step, and step bottom coordinates with valve rod；Institute
Stating gasket ring adaptive with step, described gasket ring cylindrical coordinates with upper valve body inner surface, gasket ring
Inner circle coordinates with valve rod；It is provided with main sealing assembly below described gasket ring；Described upper valve body is provided with one
Leak hunting aperture, described leak hunting aperture is arranged on upper valve body inner surface and gasket ring cylindrical cooperation position, described stifled
Head assembly is arranged on outside upper valve body.
Preferably, described leak hunting aperture is through hole, and described leak hunting aperture is shaped as step-like, straight outside leak hunting aperture
Footpath, more than detecting inside hole, is provided with female thread outside described leak hunting aperture.
Preferably, described plug component include plug and sealing ring, described plug be provided with external screw thread and with inspection
Adaptation outside small opening, plug front end center position is provided with the round bar identical with size inside leak hunting aperture, described
Sealing ring center is provided with outside the through hole adaptive with round bar, sealing ring external diameter and leak hunting aperture adaptive.
Preferably, described round bar coordinates through sealing ring with leak hunting aperture inner surface.
Preferably, secondary seal assemblies, described secondary seal group are also included between described upper valve body and valve rod
Part is arranged on above gasket ring, and described secondary seal assemblies coordinates with gasket ring.
This utility model arranges leak hunting aperture in the above position of upper valve body valve rod main sealing assembly, and installs plug
Assembly.When pressure testing or on-line maintenance, take off plug component, then observe pressure reduction by leak hunting aperture and change,
And then judging that whether damaged valve rod main sealing assembly or existing defects, it is ensured that its sealing property is reliable；Secondly,
Plug component is made up of plug and sealing ring, leak hunting aperture can play the effect of seal isolation, reduce
The risk that after the inefficacy of valve rod primary seal, medium leaks outside.Therefore, this structure is effectively guaranteed valve seal
Reliability, improve the serviceability of valve.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1-secondary seal assemblies, 2-upper valve body, 3-valve rod, 4-main sealing assembly, 5-gasket ring,
Outside 6-sealing ring, 7-plug, 8-leak hunting aperture, inside 9-plug component, 10-leak hunting aperture, 11-leak hunting aperture,
12-round bar.
