Current pressure gauge base is that lower end connection medium pipeline, upper end are connected with the supervisor of pressure tapping mostly,
Supervisor is closed when being provided with main valve on supervisor to dismantle pressure gauge；The periodic check of pressure gauge is needed it from pressure gauge base
It removes and send to verification agency, put in back after verification is qualified, often dismounting can make pressure tapping abrasion influence leakproofness, can also be because
Vibration leads to loose-parts in pressure gauge, influences measurement accuracy and service life, and pressure duct or toxic, flammable etc.
For the pressure gauge of hazardous medium pipeline in disassembly, there is also certain pressure or hazardous mediums in supervisor, there is certain risk,
In addition, in industrial occasions, in order to avoid frequent round-trip production scene and verification agency, often tens of or even up to a hundred pieces of pressure
Power table concentration removes verification, and field personnel can not observe the pressure value of production scene each point in real time during this period, there is peace
Full hidden danger.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of gauge stand for exempting to tear safety check pressure open, can solve existing
There is pressure gauge base to need to dismantle down on pressure gauge and verify, leads to the precision and service life for being easy to influence pressure gauge, also
Can there are problems that security risk.
The utility model is achieved through the following technical solutions：
A kind of gauge stand for exempting to tear safety check pressure open, including vertical supervisor, the supervisor upper end is connected with pressure gauge and connects
Head is provided with main valve on the supervisor, further includes relief tube, surge tank, calibrated tube, the inner end point of the relief tube and calibrated tube
Not Lian Tong supervisor between main valve and pressure tapping, extend downwardly after the outer end insertion surge tank of the relief tube, it is described to let out
It is provided with relief valve in pressure pipe, certificated valve is provided on the calibrated tube, the top and bottom end of the surge tank are connected separately with
It is connected to upper hole, the lower opening of inner cavity, the upper hole, lower opening are connected separately with upper plug head, lower end cap, and the top of the surge tank also connects
It is connected with exhaust pipe, is provided with exhaust valve on the exhaust pipe.
The further scheme of the utility model is, the side wall of the surge tank is provided with form, along height on the form
At relief tube insertion surge tank, lower edge is lower than the external port of relief tube, convenient for the liquid of the neutralizer added in observation surge tank
Position.
The further scheme of the utility model is that lower recess, the lower opening is set to minimum for the bottom end of the surge tank
Place, convenient for discharge neutralizer.
The utility model compared with prior art the advantages of be：
By relief tube will be responsible in remaining pressure or hazardous medium guide to surge tank, the inner cavity of surge tank can be with
Be effectively reduced pressure, then by exhaust pipe discharge pressure, and surge tank can by upper hole, lower opening addition, discharge can in
It with the neutralizer of hazardous medium, eliminates safe hidden trouble, from the gas calibration pressure gauge of calibrated tube input normal pressure, does not need to tear open
Table, table work precision caused by pressure gauge is torn in elimination, which open, to be influenced, and can successively verify each pressure gauge in production scene, not shadow
Ring the normal use of other pressure gauges.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the use state diagram of the utility model.
Specific embodiment
A kind of gauge stand for exempting to tear safety check pressure open as shown in Figure 1, including vertical supervisor 1,1 upper end of the supervisor connects
It is connected to pressure tapping 2, is provided with main valve 3 on the supervisor 1, further include relief tube 4, surge tank 6, calibrated tube 14, it is described to let out
The inner end of pressure pipe 4 and calibrated tube 14 is respectively communicated with the supervisor 1 between main valve 3 and pressure tapping 2, the outer end of the relief tube 4
It is extended downwardly after insertion surge tank 6, relief valve 5 is provided on the relief tube 4, is provided with certificated valve on the calibrated tube 14
15, the surge tank 6 is hollow cylinder, and top is provided with upper hole and the exhaust pipe 9 of connection inner cavity, the exhaust pipe 9
On be provided with exhaust valve 10, the bottom end of the surge tank 6 is provided with the lower opening of connection inner cavity in lowest part to lower recess, described
Upper hole, lower opening are connected separately with upper plug head 7, lower end cap 8, and the side wall of the surge tank 6 is provided with form 13, the form 13
Upper edge is higher than relief tube 4 and is inserted at surge tank 6, and lower edge is located at the external port of 6 inner cavity of surge tank lower than relief tube 4.
The supervisor 1, relief tube 4, surge tank 6, exhaust pipe 9, calibrated tube 14 are all made of stainless steel and are made, and are responsible for 1, pressure release
Pipe 4, calibrated tube 14 caliber be 15mm, the caliber of exhaust pipe 9 is 8mm, and the diameter of surge tank 6 is 80mm, and axial length is
The stainless steel needle-valve of corresponding diameter is respectively adopted in 150mm, main valve 3, relief valve 5, exhaust valve 10, certificated valve 15, is responsible for 1, pressure release
Pipe 4, surge tank 6, exhaust pipe 9, main valve 3, relief valve 5, exhaust valve 10, calibrated tube 14, between certificated valve 15 using being welded to connect,
Upper hole, lower opening diameter be the threaded hole of 10mm, upper plug head 7, the bolt shape that lower end cap 8 is correspondingly-sized, the form 13 is
It slots in 6 side wall of surge tank, is then inserted into transparent material, transparent material select according to medium type the kind of its resistance to corrosion
Glass may be selected in class, such as acid medium.
As shown in Fig. 2, the lower end of supervisor 1 is connected to medium pipeline 11 by screw thread or welding, pressure is installed in pressure tapping 2
Power table 12, when normal use, main valve 3 is opened, and relief valve 5, exhaust valve 10, certificated valve 15 are closed, and upper plug head 7, lower end cap 8 are closed
Upper hole, lower opening；When verifying pressure gauge 12, main valve 3 is first closed, if being hazardous medium in medium pipeline 11, first removes upper plug head
7, neutralizer is poured into surge tank 6 from upper hole, the amount of pouring into is observed by form 13, until liquid level covers relief tube 4 positioned at slow
The external port about 1cm for rushing 6 inner cavity of tank, puts in back upper plug head 7, and then the remaining media being responsible in 1 is discharged into slow by opening relief valve 5
It rushes in tank 6, the volume of 6 inner cavity of surge tank is far longer than the remaining space of supervisor 1, the pressure of remaining media can be greatly reduced,
