Description
Technical field
The technical field of gas valve specific purpose tool is the utility model is related to, is especially that one kind connects for gas piping three
The instrument of head ventilation.
Background technology
Gas valve is a kind of safe corollary apparatus of new gas pipeline engineering, for blocking, connecting, adjusting in pipeline
Gas, have good control characteristic and close sealing property, it is a variety of suitable for town gas, liquefied petroleum, natural gas etc.
On gas medium pipeline.Generally, gas valve is connected with a three-way connection, and two reduction of fractions to a common denominators of the three-way connection do not connect with system pipeline
Connect, three-way interface is then blocked by plugging structure.The plugging structure of prior art includes tamper plate, gag and sealing
External screw thread is equipped with the periphery wall of pad, tamper plate and gag, the polygon being provided with the middle part of tamper plate for special spanner insertion leads to
Hole, gag top surface are provided with the polygon boss blocked for special spanner, and sealing gasket is located at what open lumen perisporium was provided with
On step, gag is threaded in open lumen and its bottom is pressed on sealing gasket, and tamper plate is located above gag and spiral shell
Line is connected to opening.So, tamper plate and gag must use special spanner just to back out, although this, which is served, prevents other people
The illegal purpose for usurping combustion gas, still, needing to unseal three-way interface in use, administrative staff need temporary close pipeline
The combustion gas inside conveyed, otherwise after tamper plate and gag is backed out, a large amount of combustion gas can outwards spray from the opening, therefore,
Must be on the premise of pipeline total valve be closed, operating personnel could operate, and can not be operated with gas, so as to whole operation process
It is very troublesome, time-consuming.
Based on the above situation, engineers devise the instrument for the ventilation of gas piping three-way connection, can be in band gas
In the case of operation.CN 105257944A and the CN 203500728U as disclosed in State Intellectual Property Office, for gas piping
The instrument of three-way connection ventilation generally comprises the ball valve being connected with closure interface one end hermetic seal in three-way connection；Nut, institute
The one end for stating nut is connected with ball valve hermetic seal；For the push rod for opening closure interface, the push rod passes through the axial direction of nut
Hole is set and push rod is slidably connected with nut, and air-tight structure is provided between axial hole and push rod.
Said structure still has certain deficiency：Because instrument is all-sealed structure, and it is not provided with detection instrument
Whether closure interface one end top of three-way connection is worn to the structure opened, so, operating personnel's inconvenience confirmation instrument is
It is no closure interface one end of three-way connection top has been worn it is open-minded.
Utility model content
