Description
Technical field
The utility model belongs to press device security technology area, and in particular to a kind of burst pressure measurement dress of safety valve
It sets.
Background technique
The process unit and storage and transportation equipment of the industries such as chemical industry, handled material are mostly fluid (liquid, gas or steaming
Vapour).It is required to meet technique and storing, the equipment for handling these fluid foods should have the ability of certain receiving pressure.
The bearing capacity of equipment generally equipment design when just given, once the actual pressure of fluid more than equipment bearing capacity,
Equipment just will appear excessively plastic deformation even rupture and be destroyed.So-called safety valve is that one kind prevents fluid pressure device
The safety device that superpressure is destroyed occurs.The equipment of measurement safety valve burst pressure is using mechanical compression table and video camera at present
Mode, it is inconvenient for operation, and burst pressure measurement inaccuracy, the utility model proposes a kind of surveys of the burst pressure of safety valve thus
Measure device.
Summary of the invention
The purpose of this utility model is: a kind of burst pressure measuring device of safety valve is provided, to solve measurement dress at present
Set inconvenient, the technical problem of burst pressure measurement inaccuracy.
To solve this technical problem, the technical solution of the utility model is:
A kind of burst pressure measuring device of safety valve, the measuring device include: pressurized equipment 1, digital display manometer
2；
The pressurized equipment 1 has at least three input/output ports；The digital display manometer 2 at least two, and
It is connect with pressurized equipment 1；Safety valve 3 to be blasted is connect with the pressurized equipment 1.
The pressurized equipment 1 is to be threadedly coupled with 2 connection type of digital display manometer.
The pressurized equipment 1 is to be threadedly coupled with 3 connection type of safety valve.
The pressurized equipment 1 is hydraulic power source.
The pressurized equipment 1 is pneumatic supply.
The pressure range of the pressurized equipment 1 is 0~250MPa.
The beneficial effects of the utility model are: the burst pressure measuring device of the utility model safety valve has operation letter
Single, burst pressure records the advantages that accurate, and the burst pressure particularly suitable for safety valve measures environment.
Detailed description of the invention
Fig. 1 is the operation principle schematic diagram of the burst pressure measuring device of the utility model safety valve；
Wherein, 1- pressurized equipment, 2- digital display manometer, 3- safety valve.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples:
The schematic diagram for the burst pressure measuring device that Fig. 1 is the utility model is please referred to, the measuring device includes: to add
Press equipment 1, digital display manometer 2；The pressurized equipment 1 is with there are three input/output ports；The digital display manometer 2 is band peak
It is worth the digital display manometer of writing function, number is two, and is connect with pressurized equipment 1；Safety valve 3 to be blasted adds with described
Equipment 1 is pressed to connect.
The method for carrying out safety valve blasting measurement using the measuring device of the utility model is as follows:
Pressurized equipment 1: hydraulic bed uses plunger type principle, and has at least three input/output port, and pressure range is 0
~250MPa.
Digital display manometer 2: digital display manometer is the pressure gauge of customization, has pressure peak writing function, can press
Numerical value is read out in 5S after the appearance of power peak value, pressure limit is 0~120MPa, and precision is 0.1 grade.In order to ensure measurement
Accuracy, use two pieces of pressure gauges in measuring device, if the two reading value difference is larger, need to measure, if the two
It is not much different, then it is assumed that numerical value can be accepted and believed, and taking the two average value is the burst pressure of safety valve
It is pressurizeed using hydraulic bed to safety valve, is carried out simultaneously using two pieces of digital display manometers with peak records function
Burst pressure is acquired, taking its average value is the burst pressure of safety valve.
Safety valve 3: this measuring device can be with the pressure of explosion for 0~100MPa, therefore safety valve burst pressure exists
It can be measured with the method when 100MPa or less.
The application method of the utility model:
First the digital display manometer 2 by two pieces with peak records function is respectively installed to two interfaces of hydraulic bed, and leads to
Electricity will first count before pressurization by another interface of the access hydraulic bed of safety valve 3 to be blasted after digital display manometer 2 is stablized
Aobvious pressure gauge 2 " zero setting ", then turns the pressurized handgrip in hydraulic bed, uniform pressurization is carried out to safety valve 3, until safety valve 3
Until explosion, reads the peakreading on two pieces of digital display manometers 2 with peak records function respectively at this time, and record, take it
Average value is the burst pressure of safety valve 3, then removes safety valve 3.
Hydraulic power source or pneumatic supply can be used in pressurized equipment 1 in the measuring device of the utility model, and digital display manometer 2 can
Think two or more, is averaged.
