Abstract
This utility model provides a kind of pressure tapping, including pressure tapping main body, relief hole, airtight screw.Pressure tapping main body is divided into upper and lower two parts, and upper dimension is less, and lower dimension is relatively big, and cross section constitutes an isosceles triangle shape, and, pressure tapping main body is the column structure of hex shape.According to pressure tapping described in the utility model, reached the purpose of quick pressure releasing by dismountable plug, the device of overbottom pressure in pressure tapping can be laid down.
Description
Technical field
This utility model relates to fluid machinery, particularly to a kind of pressure tapping.
Background technology
During Pressure gauge is replaced, it is impossible to directly pressure release, can only slowly turn on Pressure gauge and carry out pressure release, if valve
Tight or have overbottom pressure, at this moment overbottom pressure easy scathing eyes and pollute environment when connection port upwards sprays.
Utility model content
The purpose of this utility model is the demand for prior art, proposes a kind of pressure tapping, by detachably
Plug reach the purpose of quick pressure releasing, the device of overbottom pressure in pressure tapping can be laid down.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of pressure tapping, including: pressure tapping main body, relief hole, airtight screw.
Further, pressure tapping main body is divided into upper and lower two parts, and upper dimension is less, and lower dimension is relatively big, horizontal
One isosceles triangle shape of section constitution, and, pressure tapping main body is the column structure of hex shape.
Further, pressure tapping body top band external screw thread, Pressure gauge, lower side are installed by female thread in bottom
Have a relief hole, equipped with airtight screw inside relief hole.
Further, described airtight screw is the flat cheese head screw of interior hexagonal.
Accompanying drawing explanation
Fig. 1 is pressure tapping front view of the present utility model.
Fig. 2 is pressure tapping top view of the present utility model.
(note: the shown structure in accompanying drawing, simply to illustrate that the signal of this utility model feature, is not intended to according to attached
Structure shown in figure.)
Detailed description of the invention
As shown in Figure 1-2, according to pressure tapping described in the utility model, including: pressure tapping main body 1, pressure release
Hole 2, airtight screw 3.
Wherein, pressure tapping main body 1 is divided into upper and lower two parts, and upper dimension is less, and lower dimension is relatively big, cross section
Constitute an isosceles triangle shape.Further, pressure tapping main body 1 is the column structure of hex shape.
Pressure tapping main body 1 upper bands external screw thread, bottom is by female thread installation Pressure gauge, and lower side has one
Relief hole 2, relief hole 2 is internal to be tightened airtight screw 3 during use equipped with airtight screw 3, and combination constitutes a set of pressure tapping
Device.
Wherein, described airtight screw 3 is the flat cheese head screw of interior hexagonal.
During application, the interior airtight screw of hexagonal flat round 3 spanner is installed in pressure tapping main body 1, first-class Pressure gauge,
When Pressure gauge changed by needs, first pull down the interior airtight screw of hexagonal flat round 3, because sealing between Pressure gauge and joint, therefore pressure liquid
Or gas will not leak, the most slowly unclamp Pressure gauge, arrive relief hole 2 position, if there being overbottom pressure will leak from relief hole 2,
Do not have overbottom pressure to leak from Pressure gauge hole eyes accident of hurting sb.'s feelings.After completing, install the interior airtight screw of hexagonal flat round 3, then on
Good pressure tapping main body 1, i.e. completes Pressure gauge replacement operation.
According to pressure tapping described in the utility model, can fast and safely change Pressure gauge, will not stab because of overbottom pressure
Eyes and pollution environment.
The above, preferred embodiment the most of the present utility model, it is not intended to limit protection of the present utility model
Scope, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, should be included in
Within protection domain of the present utility model.
