China Safety Valves Quality Testing Machine

Safety Valves Quality Testing Machine

Application: Used for testing the quality of safety valves with small DN, and can be widely used in large and medium - sized enterprises like Chemical Plants, Oil Refineries, Power Plants, metallurgical Plants, Mines and Technical Supervision Departments.Can be used in reception and sampling inspection process for enterprises, in safety supervision process for Technical Quality Supervision and Inspection Department; in pre-installation inspection process for Contractor or Client and in the retest after the reparing for Repair Units.
Design Features:1. This kind of test machine is complied with GB/T13927-92 Standard, and can test flanged gate valves & cut-off valves with DN≤150mm.2. The testing and inspection scope as follows, Shell strength test, Water/ Air tightness test for the Sealing surfaces, Reverse seal test, Packing sealtest and Flange seal test. 3. No elelctrisity needed. Safe and reliable guaranteed.4. 180 degrees turn by hand.5. Easy to operate and little maintenance for long term.6. Large scope of application.7. Covers an area of about 1 sqm and adequate drainage place needed.
Technical Parameters:1. Structure: Unidirectional manual clamping seat structure.2. Input Test Medium: Room temperature water amd 0.6MPa compressed air. Pressurized nitrogen and a bottle of air should be provided by users.3. Maximum test pressure for each scope of Test DN:DN≤40506580100150 PS201512106.44
With threaded ends and flanged valves size range from DN 15 (1/2") - DN 400 (16"),
Test pressure up to 5000psi (gas) or 9000psi (water), test media Water, Nitrogen.
According to the international test standard API, ISO, and DIN.
For the original of main components of the test bench, pumps and booster are
The products of the United States of America. High pressure valves are
The products of the Switzerland.
1. Gas and Water Test Bench Specifications
50: 1 ratio air-driven booster used the minimum precharge pressure 400psi,
The max output pressure up to 4300psi.
One high pressure gas regulator used.
100: 1 ratio air-driven pump used the max output pressure up to 9000psi.
High pressure nitrogen bottles can be used as the precharge gas to
Get high pressure test media.
100 psi air compressor can be used to supply driving air.
Gauges: "three pieces φ150 dial panel-mounted gauges, 0.4% accuracy full scale, 10000psi, 5000psi and 1000psi.
An auxiliary gauge port is provided with quick disconnects for other gauge range.
All high pressure valves, tubing and fittings are stainless steels.
All gauges, valves and regulators are panel mounted.
2. Clamping Equipment
Clamping equipment is used for testing with water and nitrogen including
Two clamping units (DN15-200, DN200-400).
The heavy duty constructed automatic clamping system with
A double acting hydraulic cylinder
Which is operated from the control panel.
