Description

Valve pressure testing device in parallel
Technical field
The utility model relates to a kind of device of valve pressure testing test, and is particularly a kind of to the device that is applied to the long distance pipeline engineering, the valve in the fields such as storehouse class engineering, boiler engineering of standing carries out pressure testing.
Background technology
According to standard GB50235 requirement, remove before valve is installed and to carry out the presentation quality inspection, (nominal pressure is less than 1.0MPa also should to carry out housing pressure test and leakage test, and nominal size is more than or equal to the gate valve of 600mm) can not carry out housing pressure test and flashboard leakage test separately), test period must not be less than 5min, before valves test in the past, to weld the technology straight length that two segment length are at least 1.5m in the valve both sides, respectively weld a pressure testing head at technology straight length two ends.For example in the construction of field, long distance pipeline station, a large amount of valves all needs to carry out the pressure testing of this kind mode, and the cycle is long, loss measure materials, and cost is big.
Summary of the invention
The purpose of this utility model is intended to solve the problems referred to above that above-mentioned valve pressure testing mode exists in using, and provides a kind of reasonable in design and effectively avoid the valve pressure testing device in parallel of above-mentioned drawback.
The purpose of this utility model can realize by following technical solution:
This valve pressure testing device in parallel, comprise header and pressure indicating mechanism, described pressure indicating mechanism is connected with described header, also is provided with the exhaust gear that is connected with described header, the tube wall of described header is provided with a plurality of openings, and described opening part is provided with test valve bindiny mechanism.Described header refers to the body section for the test valve.The effect of described exhaust gear is the gas that discharges when described header is used for pressure test in this header.Being provided with a plurality of openings and the effect that is provided with test valve bindiny mechanism at described opening part at the tube wall of described header is that the convenient header of realizing is connected with a plurality of test valves simultaneously and simultaneously a plurality of valves is tested, thereby improves the work efficiency to the valve test.The tube wall of described header is provided with the opening that a plurality of openings refer to be provided with at described header the connection test valve more than 2 and 2.
The purpose of this utility model can also be achieved through the following technical solutions:
Described valve bindiny mechanism comprises pipe nipple and is arranged at be not connected with the described header flange of end of this pipe nipple.Can conveniently realize testing being connected of valve and described header by described pipe nipple and described flange.That the described valve bindiny mechanism of this structure has is simple in structure, be convenient to arrange the advantage of installing and using.Be provided with the test pump that is connected with described header, described pressure indicating mechanism comprises the pressure test pipe that is connected with described header and the tensimeter that is connected with this pressure test pipe.The effect of described test pump is supercharging in the described header.Comprise that described pressure test pipe and described manometric pressure indicating mechanism have advantage simple in structure, easy to install.Be conducive to improve the convenience of use by being connected of described test pump and described pressure indicating mechanism and described header.The pipe nipple caliber size of described valve bindiny mechanism is inequality.The effect that described different caliber size pipe nipples are set is the convenient connection test that realizes different caliber size valves.The vertical full penetration of described pipe nipple is welded on the described header, and is provided with the liquid discharge pipe that is connected with described header.Vertical full penetration welding manner connects described pipe nipple and described header has being connected firmly and is conducive to make the advantage of processing.The effect of described liquid discharge pipe is after the valve test is finished, and discharges the liquid in the described header.
The beneficial effects of the utility model: because by a plurality of openings on the tube wall of described header, pressure indicating mechanism, exhaust gear and described header and test valve bindiny mechanism thereof, can realize once the test to a plurality of valves, it has solved the repetitive operation of the independent pressure testing of valve, reduce valve pressure testing measure materials use amount and pressure testing device dismounting number of times simultaneously, can shorten the pressure testing cycle again, reduce construction cost and security risk, guarantee the continuity of installation, finish valve pressure testing construction efficiently.So, the utlity model has rational in infrastructure, easy to use, be conducive to improve advantages such as valve pressure testing construction working efficient.
