Description
Technical field
The utility model relates to tank car breathing relief valve field, particularly refers to a kind of suction valve pick-up unit of tank car breathing relief valve.
Background technology
Tank body of tank car breathing relief valve is pressure in Reasonable adjustment tank, guarantees the vitals that liquid goods (liquid goods refers to all liq product) is transported safely.When pressure reaches level pressure in tank, drainage effect must be played; When pressure in tank produces negative pressure, must play suction effect, hence obtain one's name " breathing relief valve ", and its effect effectively adjusts pressure in tank at any time.During tank car, tank breathing type safety valve must be changed, and by strict checking experiment, can be recycled.The Ministry of Railways of China technical regulation specifies: the breathing relief valve that light oil type tank car is installed, and when pressure reaches 150 ± 20kPa in tank, must play drainage effect; When negative pressure is 1 ~ 2kPa, suction effect must be played.At present, the maintenance process of tank breathing type safety valve is: decompose → clean → change part → assembling → entrucking use procedure.
Each maintenance factory carries out bulk testing to whole breathing relief valve after carrying out decomposition maintenance assembling by repair in shop regulatory requirements to breathing relief valve more at present.Adopt existing breathing relief valve test unit, after needing breathing relief valve all to assemble, just can test.When the suction pressure of breathing relief valve is not inconsistent requirement, need breathing relief valve to pull down from testing table, again disintegrating breath formula safety valve, the compression dynamics in regulating spool between spring and spring base.After re-assemblying, more again test suction pressure and drainage pressure.If heavily must dismantle again defective and decompose adjustment, the duplication of labour affects production efficiency.
Summary of the invention
The purpose of this utility model is exactly the suction valve pick-up unit that will provide a kind of tank car breathing relief valve, suction pressure for the suction valve to breathing relief valve detects, which obviate repeated removal Sum decomposition breathing relief valve to adjust the test of breathing relief valve, improve production efficiency.
For achieving the above object, the utility model is by the following technical solutions: the utility model provides a kind of suction valve pick-up unit of tank car breathing relief valve, for testing the suction pressure of suction valve, its special character is: it comprises the base of middle its central band air hole, the periphery that described submounts is positioned at air hole is provided with circular groove, and the outside that described submounts is positioned at circular groove is also provided with depression bar; Described circular groove is provided with chassis, rubber gasket is provided with between described chassis and circular groove bottom surface, described chassis offers the first through hole, the shape of cross section of described first via bottoms mates with release valve bottom shape, described chassis coordinates the platen being connected with middle its central band second through hole, described air hole, the first through hole and the second through hole are coaxially arranged state; During work, the suction valve assembled and release valve are positioned in first through hole on described chassis, first through hole seals by the O RunddichtringO bottom described release valve, described platen is placed on the spring outwards of release valve and coordinates clamping with chassis, described depression bar presses the edge of platen, thus release valve is fixed on chassis.
Preferentially, described depression bar comprises the stepped screw be fixed on base, and described stepped screw top is connected with one end screw of cross bar, is provided with bolt in the other end screw of described cross bar, during work, described bolt presses the edge of platen, thus release valve is fixed on chassis.Such pressure rod structure is when working complete, and cross bar can rotate to the side away from circular groove around stepped screw, is convenient to the dismounting of miscellaneous part.
Further, the quantity of described depression bar is 3, and the outer circumference direction along circular groove is uniformly distributed.Release valve can be fastened on chassis by the depression bar of right quantity, also makes the cost of the suction valve pick-up unit of whole tank vehicle mounted breathing type safety valve reduce.
The utility model has the advantage of: before the suction pressure of breathing relief valve and drainage pressure are detected, the utility model is first used to detect the suction pressure of suction valve, after stand the test, assemble the accessory such as big spring, valve body valve gap again after suction valve and release valve assembly being taken out, then carry out drainage pressure test.Like this when adjusting drainage pressure, not needing to decompose dismounting breathing relief valve, only need regulate the degree of tightness of its valve gap and adjustable drainage pressure.Adopt the utility model device to avoid the duplication of labour, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: suction valve 1; Base 2 (wherein: air hole 2.1, circular groove 2.2, rubber gasket 2.3); Depression bar 3 (wherein: stepped screw 3.1, cross bar 3.2, bolt 3.3); Chassis 4 (wherein: the first through hole 4.1); Platen 6 (wherein: the second through hole 6.1); Release valve 5 (wherein: O RunddichtringO 5.1, spring 5.2; Spring base 5.3).
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but this embodiment should not be construed restriction of the present utility model.
The suction valve pick-up unit of a kind of tank car breathing relief valve shown in Fig. 1, for testing the suction pressure of suction valve 1.It comprises the base 2 of middle its central band air hole 2.1, the periphery that base 2 is positioned at air hole 2.1 is above provided with circular groove 2.2, the outside that base 2 is positioned at above circular groove 2.2 is also provided with three depression bars, 3, three depression bars 3 and is uniformly distributed along the outer circumference direction of circular groove 2.2.Depression bar 3 comprises the stepped screw 3.1 be fixed on base 2, and stepped screw 3.1 top is connected with one end screw of cross bar 3.2, is provided with bolt 3.3 in the other end screw of cross bar 3.2.
Circular groove 2.2 is provided with chassis 4, between chassis 4 and circular groove 2.2 bottom surface, is provided with rubber gasket 2.3.Shape of cross section chassis 4 offered bottom the first through hole 4.1, first through hole 4.1 mates with release valve 5 bottom shape.Chassis 4 coordinates the platen 6 being connected with middle its central band second through hole 6.1, air hole 2.1, first through hole 4.1 and the second through hole 6.1 are in coaxially arranged state.
During utility model works, base 2 is placed on testing table, the bottom of its air hole 2.1 connects vacuum pump, the suction valve 1 assembled and release valve 5 are positioned in first through hole 4.1 on chassis 4, first through hole 4.1 seals by the O RunddichtringO 5.1 bottom release valve 5, coordinate clamping with chassis 4 outside the spring 5.2 that platen 6 is placed on release valve 5, the bolt 3.3 of depression bar 3 presses the edge of platen 6, thus release valve 5 is fixed on chassis 4.Open vacuum pump, because suction valve 1 when negative pressure is 1 ~ 2kPa must play suction effect, therefore when negative pressure is less than 1kPa, suction valve 1 plays suction effect, only need increase plain washer between spring base 5.3 and spring 5.2, regulate its pressure; When suction valve 1 plays suction effect when negative pressure is greater than 2kPa, change spring 5.2 or spring base 5.3, regulate its pressure.After stand the test, unclamp the bolt 3.3 of depression bar 3, suction valve 1 and release valve 5 assembly are taken out, then assembles the accessory such as big spring, valve body valve gap, then carry out drainage pressure test.
The content be not described in detail in this instructions, belongs to the known prior art of those skilled in the art.
