Abstract
The utility model provides a pipeline pressure fluctuation experiment device. Two input ends of a medium box body are respectively connected with an overflow valve I and an overflow valve II; a pump body is arranged between the overflow valve II and the output end of the medium box body; the outer end of the overflow valve I is provided with an electromagnetic valve, and the outer end of the overflow valve II is provided with a pressure meter; and the electromagnetic valve and a pressure detection unit are respectively connected with two ends of a pipeline with the length being 500mm. The line pressure fluctuation experiment device is beneficial to improving the yield of products and improving the examination effect. When a water pump starts working, the electromagnetic valve is turned off, and part of the pressure of a medium is discharged when the medium flows through the overflow valve, so that the required pressure in the pipeline can be reached instantaneously, and then the electromagnetic valve is turned on to discharge the pressure over and over again; and two ends of a pipe fitting and the pipeline with the length of 500mm form a set of samples, the pressure is pressurized from 0.1MPa to 2.5MPa to be taken as one-time circulation, the circulation is performed for 25 times to 35 times at every one minute, and a connection part between the pipe fitting and a steel pipe can not leak and fall off when the circulation is continued for 10,000 times.
Description
Technical field
The utility model relates to the performance test apparatus that is used for pipe fitting, relates in particular to a kind of line pressure fluctuation check device.
Background technology
Pipe fitting is the part that pipe is connected into pipeline, generally can be divided into socket fitting, threaded fitting, flanged fitting and weld-end fittings four classes.Existing stainless steel clamp-press type pipe, stainless steel lathe dog joint and the connection thin-wall stainless steel of being used for, after production and processing is finished, need carry out certain pressure surge proving installation and guarantee that this pipe fitting has good withstand voltage and sealing property, be that pipe fitting and steel pipe connecting portion are answered ne-leakage and obscission, if adopt existing simple and crude detection means, then can't guarantee validity.
The utility model content
At above defective, the purpose of this utility model provides a kind of qualification rate that helps improving product, improves test effect, easy to operate line pressure fluctuation check device, to solve many deficiencies of prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of line pressure fluctuation check device, comprise solenoid valve, surplus valve I, surplus valve II, the pump housing, medium casing, two input ends of described medium casing connect surplus valve I and surplus valve II respectively, between surplus valve II wherein and the medium casing output terminal pump housing are set; The outer end of described surplus valve I is provided with solenoid valve, and the outer end of described surplus valve II is provided with tensimeter; This solenoid valve and pressure sensing cell are that the pipeline two ends of 500mm are connected with length respectively.
The beneficial effect of line pressure fluctuation check device described in the utility model is: carry out the pressure surge test of pipe fitting by the combination that water pump, surplus valve, solenoid valve, pressure valve are set, easy to operate, help improving the qualification rate of product, improve test effect; When water pump was started working, closed electromagnetic valve, medium were let out a part of pressure through surplus valve, made that moment reaches the pressure of wanting in the pipeline, and solenoid valve is opened pressure release then, makes moment pressure release in the pipeline, so circulates; Pipe fitting two ends and length are the pipeline of 500mm, form one group of sample, and being forced into 2.5MPa from 0.1MPa is a circulation, test(ing) medium can be tap water, per minute should carry out (30 ± 5) individual circulation, continues 10000 circulation times, and pipe fitting and steel pipe connecting portion reach ne-leakage and obscission.
