Background technology
In pipeline, manifold pressure is frequently not constant, and therefore people tend not to find because of variations in line pressure
The potential safety hazard that brings, just in daily life, running water generally requires booster pump where floor is higher when conveying to be carried out
Supercharging could be by the top of hydraulic pressure to floor, and as moisture content is incompressible, booster pump can be produced when startup and stopping
Hydraulic shock, the pressure differential change that its produces moment are very large, for more easily causing rupture where fragility on pipeline
And infiltration, but be the change that cannot notice loine pressure in people at ordinary times, be therefore necessary to design a kind of dedicated for
The valve of signal piping pressure change, accesses and can represent constantly when the pressure condition in preceding pipeline in water system.
Utility model content
The problems referred to above are based on, the utility model purpose is to provide a kind of pipeline testing pressure valve, can represent pipeline internal pressure in real time
Power size and pressure change, and it is next according to the pipeline for accessing different pressures scope, to change the pressure measurement spring of different elastic forces
Meet different use occasions.
For problem above, there is provided following technical scheme：A kind of pipeline testing pressure valve, including valve body and is arranged in valve body
Valve pocket, be respectively equipped with inlet and outlet on the valve body, the import with outlet connected by valve pocket, the valve outer wall position
Pressure tap is provided with the top of valve pocket, in the pressure tap, pressure measuring cavity is provided with, between the pressure measuring cavity and valve pocket, pressure measurement is provided with
Hole；The pressure tap is provided with threaded connection in removable pressure measurement lid, and the pressure measurement is covered and is provided with through hole；The through hole and survey
Pressure is inserted with pressure measuring rod between hole, and described pressure measuring rod one end passes through hole and is exposed to formation pressure-measuring head, the other end outside pressure measurement lid
Enter in valve pocket through pressure tap；Locating ring is provided with the middle part of the pressure measuring rod, the locating ring is located in pressure measuring cavity, the positioning
Pressure measurement spring is provided with above ring, and the pressure measurement spring one end is offseted with locating ring, and the other end is offseted with the bottom surface of pressure measurement lid.
The utility model is further arranged to, and the outer wall that the pressure measuring rod is located in pressure tap is provided with two seals groove,
Sealing ring is equipped with the seal groove.
In said structure, sealing ring can improve the sealing property between pressure measuring rod and pressure tap, it is to avoid the liquid in valve pocket
Leak out.
The utility model is further arranged to, and the pressure-measuring head is provided with the pressure quarter for indication valve cavity pressure size
Scale designation, the pressure scale mark point third gear, respectively yellow paint mark, green paint mark, red paint mark from top to bottom.
In said structure, when pressure is less, pressure measurement spring force promotes pressure measuring rod to decline more than valve cavity pressure, this
When pressure measuring rod end expose pressure scale mark show yellow paint mark prompting under-voltage；When pressure is held with pressure measurement spring force
At ordinary times, pressure measuring rod pushes up compression pressure measurement spring under the effect of the pressure, and now the pressure scale of pressure measuring rod is marked to overhanging
Green of sening as an envoy to paint mark exposes prompting normal pressure；When pressure is excessive exceed pressure measurement spring elastic force when, pressure measurement spring is complete
Full compression, now pressure measuring rod make under the effect of the pressure pressure scale mark expose through hole completely, make red paint identify expose
Prompting overvoltage, so as to point out people's manifold pressure too high；When manifold pressure is unstable, pressure measuring rod can be with pressure change
Constantly flexible, current pressure condition in people's pipeline is reminded with this.
The utility model is further arranged to, and the pressure measurement spring is changeable type.
In said structure, as different pipeline pressure scopes is differed, the survey for changing different elastic force therefore can be passed through
Pressing spring is meeting the pressure measurement demand of different pressures pipeline.
The utility model is further arranged to, and the inner wall coarse angle value of the pressure tap is between Ra0.4 to Ra1.6.
In said structure, due to can ceaselessly rub with the change of pressure between the sealing ring and pressure tap inwall of pressure measuring rod
Wipe, the surface roughness of such as pressure tap inwall is excessively coarse, sealing ring can be made rapidly to lose sealing function, while smooth inwall
Friction is effectively reduced, so as to improve the sensitivity of pressure measurement.
The beneficial effects of the utility model：By changing the spring of different elastic force, can be used for the pipeline of various pressure limits
Pressure measurement, can represent current pressure situation in pipeline in real time, and good airproof performance No leakage, pressure measurement are sensitive.
