Description
Technical field
The technical field of gas valve specific purpose tool is the utility model is related to, is especially a kind of deblocking work of single piece type threeway
Tool.
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 single piece type threeway, and single piece type threeway refers to that one end air inlet one is brought out
One of passage of gas, i.e. threeway is blocked by plugging structure.The plugging structure of prior art includes tamper plate, gag
And sealing gasket, external screw thread is equipped with the periphery wall of tamper plate and gag, is provided with the middle part of tamper plate for special spanner insertion
Polygonal through hole, gag top surface are provided with the polygon boss blocked for special spanner, and sealing gasket is located at open lumen week
On the step that wall is provided with, gag is threaded in open lumen and its bottom is pressed on sealing gasket, and tamper plate is located at gag
Top and it is threaded in opening.So, tamper plate and gag must use special spanner just to back out, although this is served
Prevent other people from illegally usurping the purpose of combustion gas, still, in one end deblocking for needing to be blocked single piece type threeway in use, management
Personnel need the combustion gas conveyed in temporary close pipeline, and otherwise after tamper plate and gag is backed out, a large amount of combustion gas can be from this
Opening outwards sprays, therefore, it is necessary on the premise of pipeline total valve is closed, operating personnel could operate, and can not be with gas
Operation, so as to which whole operation process is very troublesome, time-consuming.
Based on the above situation, engineers devise the unsealing tool of single piece type threeway, can make in the case of sparkling
Industry.CN 105257944A and the CN 203500728U as disclosed in State Intellectual Property Office, lead to for gas piping three-way connection
The instrument of gas generally comprises the ball valve being connected with closure interface one end hermetic seal in three-way connection；Nut, the one of the nut
End is connected with ball valve hermetic seal；For will block the push rod opened of interface, the axial hole of the push rod through nut 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
Technical problem to be solved in the utility model is to provide a kind of unsealing tool of single piece type threeway, and the instrument can
So that conveniently to confirm whether instrument has been worn closure interface one end of three-way connection top open-minded by operating personnel.
In order to solve the above technical problems, a kind of unsealing tool of single piece type threeway provided by the utility model, including
- the ball valve being connected with closure interface one end hermetic seal in three-way connection；
- nut, one end of the nut are connected with ball valve hermetic seal；
- be used to that the push rod opened of interface will to be blocked, the axial hole of the push rod through nut is set and push rod and nut
It is slidably connected, air-tight structure is provided between axial hole and push rod；
The nut side wall is provided with through hole, and installing plate, the installation are fixed with the port of the one end of through hole outwardly
Plate is provided with perforation, is connected with tightrope on the installing plate, in the nut outside wall surface hermetic seal be connected with the outer cover of printing opacity, institute
State outer cover to cover on through hole, the through hole will connect with the inner chamber of nut with the inner chamber of outer cover, and the tightrope is located at the interior of outer cover
In chamber.
After above structure, the utility model has the following advantages that：
Because the nut side wall is provided with through hole, installing plate is fixed with the port of the one end of through hole outwardly, it is described
Installing plate is provided with perforation, and tightrope is connected with the installing plate, in the nut outside wall surface hermetic seal be connected with the outer of printing opacity
Cover, the outer cover are covered on through hole, and the through hole will connect with the inner chamber of nut with the inner chamber of outer cover, and the tightrope is located at outer cover
Inner chamber in, therefore, when instrument, which does not wear closure interface one end of three-way connection top, to be opened, tightrope is quiet under natural situation
Only state；When instrument, which wears closure interface one end top of three-way connection, to be opened, tightrope becomes to float in the presence of air-flow
Dynamic state, so as to which operating personnel can facilitate whether confirmation instrument has connect the closure of three-way connection according to the state of tightrope
Wear open-minded in mouth one end top.
Referring between the axial hole and push rod provided with air-tight structure, the side wall of the axial hole is provided with sealing ring,
The outer circle wall of the sealing ring and push rod pushes against.It is in this manner it is ensured that air tight between axial hole and push rod.
