Abstract
The utility model discloses a portable breather valve detection device which comprises an air supply pipe, a positive and negative pressure generator and a connecting tube. The air supply pipe is connected at the shell of the positive and negative pressure generator; the suction end of the positive and negative pressure generator is connected with the breather valve through the connecting pipe; the output end of the positive and negative pressure generator is connected with a discharge pipe on which a stop valve is arranged; and a pressure detector and a pressure gauge are arranged on the connecting pipe. The portable breather valve detection device takes the air source at the field as carrier, the positive and negative pressure generator as the core and the pressure detector as the means for observation and recording to detect qualitatively and quantitatively, and is safe, convenient to take, simple and convenient to operate and can select the operation freely.
Description
Technical field
The utility model belongs to pick-up unit, particularly relates to a kind of portable vacuum pressure valve pick-up unit.
Background technology
Vacuum pressure valve is the safety attachment of petroleum and petrochemical industry, gas industry atmospheric storage tank.According to country, enterprise's relevant laws and regulations, system, must regularly carry out site inspection and detect vacuum pressure valve.At present, known vacuum pressure valve pick-up unit generally adopts electrical equipments such as air compressor, freezer compressor or fan blower to drive generation negative pressure carrier and needs vehicle-mounted moving; And the atmospheric storage tank at vacuum pressure valve place itself is exactly inflammable and explosive place, and inconvenience adopts electrical equipment to drive the detection means of generation negative pressure carrier and the operation of motor vehicles and relatively large pick-up unit; In addition, the vacuum pressure valve inspection of the character of operation is the approval to the keying state, and the detection of the vacuum pressure valve of technological property is the affirmation to keying state and technical parameter, can check or detection according to the job specification decision.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, avoid inspection, the operation blindly of vacuum pressure valve form, strengthen the controlled of atmospheric storage tank safe operation maintenance, a kind of portable vacuum pressure valve pick-up unit is provided, it can not only utilize on-the-spot wind regime, inspection to detect the positive negative pressure duty of vacuum pressure valve, and the data storage that detects is write down, carries out post analysis, printing; And can satisfy the demand that the vacuum pressure valve site inspection detects apparatus essential safety, easy to carry, easy and simple to handle and qualitative examination, detection by quantitative.
Portable vacuum pressure valve pick-up unit of the present utility model, be to constitute by air feed pipe, positive negative pressure generator, connecting pipe, the air feed pipe is connected in the shell of positive negative pressure generator, the suction side of positive negative pressure generator is connected with vacuum pressure valve by connecting pipe, the endpiece of positive negative pressure generator connects delivery pipe, and is provided with stop valve on delivery pipe.
As further improvement of the utility model, connecting pipe is provided with pressure detector and tensimeter.
Portable vacuum pressure valve pick-up unit of the present utility model is to be that carrier, positive negative pressure generator are that the essential safety of core, feature easy to carry, easy and simple to handle and pressure detector observed and recorded are qualitative examination, the detection by quantitative of means and the advantage that can select operation voluntarily with on-the-spot wind regime.

Portable vacuum pressure valve pick-up unit of the present utility model is to be made of air feed pipe 1, positive negative pressure generator 2, connecting pipe 3.Air feed pipe 1 is connected in the shell of positive negative pressure generator 2, and the suction side of positive negative pressure generator 2 is connected with vacuum pressure valve 4 by connecting pipe 3, is provided with pressure detector 7 and tensimeter 8 on connecting pipe 3.The endpiece of positive negative pressure generator 2 connects delivery pipe 5, and is provided with stop valve 6 on delivery pipe 5.
Further specify the utility model principle of work with reference to the accompanying drawings, wind regime (industrial wind or nitrogen) is connected with air feed pipe 1 with the flexible pipe that has rapid-acting coupling, open air intake valve 9, feel test connecting pipe port air quantity, adjusting blast are regulated nut and are observed tensimeter 8, make detecting device reach the negative pressure maximum rating, close air intake valve 9 after the affirmation; Close storage tank and breathe stop valve 10, make vacuum pressure valve reach the inspection state; With connecting pipe 3 with open and leak free breathing showering guilding valve 11 links to each other, stop valve 6 is an opening, slowly opens air intake valve 9 and observes vacuum pressure valve action and tensimeter 8 and pressure detector 7 tabular values, confirms suction condition, finishes the negative pressure inspection and detects; Slowly close stop valve 6, wind regime enters vacuum pressure valve 4 by positive negative pressure generator 2, and observes vacuum pressure valve 4 action and tabular values, confirms to close wind regime main valve and air intake valve 9 behind the expiration state, opens stop valve 6 releases, finishes the malleation inspection and detects; Remove air induction hose, connecting pipe 3, close and breathe showering guilding valve 11, open storage tank and breathe stop valve 10, the vacuum pressure valve 4 that comes into operation is finished complete inspection and is detected operation.
When checking operation, but Direct observation vacuum pressure valve 4 operating states and tensimeter 8, with qualitative definite vacuum pressure valve 4 duties; When detecting operation, can store data continuously by subsidiary pressure detector 7, and the tensimeter 8 and the pressure detector 7 of Direct observation vacuum pressure valve 4 operating states and numeral demonstration, with qualitative definite vacuum pressure valve 4 duties and later stage quantitative assessment vacuum pressure valve safe condition.
Tensimeter, pressure detector and be separately positioned on connecting pipe on interface be connected.When checking operation, can a working pressure table; When detecting operation, need the external pressure testers that uses in parallel.
This programme is applicable to that the site inspection of vacuum pressure valve duty detects, and also can be used for the site inspection of safety attachments such as spark arrester.
