Comprehensive atmospheric tank truck andtest benchVehicle mounted atmospheric tank truck test benchBreathing valve calibration station
Our company has designed and developed a portable system specifically for the safety inspection and maintenance of oil tanker trucksComprehensive test bench for oil storage tanksIt can accurately detect the positive and negative opening values and sealing performance of the breathing valve, and has also developed the MBQ seriesComprehensive test bench for atmospheric tank trucksIntegrating pneumatic clamping, vacuum and micro pressure testing, and water pressure testing, it can be widely used for atmospheric tank truckssafety valveOur company's equipment fully complies with national testing standards for the calibration of breathing valves and pressure resistance testing of pipeline water pressure. The structure is reasonable, the operation is simple, and it is easy to maintain.

The Oudimote oil storage tank accessory testing equipment is developed and manufactured according to the enterprise standard Q/SY 08007:2017 of China National Petroleum Corporation, and is used to test the tank breathing valve and hydraulic systemsafety valveThe opening pressure, flow rate, and other related parameters of the flame arrester.
Model: MST-300/2BN
The relevant technical parameters of the testing equipment are as follows:
1. Test the specifications and rated ventilation of breathing valves, hydraulic safety valves, and flame arresters:
