Description

Can stable holding relief valve device
Technical field
The present invention relates to a kind of can stable holding relief valve device, more particularly, to a kind of high degree of automation and function collection Become many safety valve maintenance platform.
Background technology
Relief valve is a kind of automatic valve, and it is not by any external force, but discharges a volume using the power of medium itself The fluid of fixed number amount, in case pressure exceedes predetermined safety value in locking system.After pressure recovers normal, close simultaneously again by row for valve Medium is stoped to continue to flow out.Relief valve be used for pressure vessel, pressure pipeline, by the device such as hot pot stove, for by protection device because System overpressure and occur explode and damage, to equipment run and personal security play important protective effect.
After relief valve is using a period of time, because the sealing surface that many reasons make relief valve occurs different degrees of damage And lead to relief valve that different degrees of leakage occurs.It is thus desirable to breakdown maintenance is carried out to relief valve leakage, keep in repair it Again pressure checking is carried out to relief valve afterwards.Sealing surface of safety valve its physical dimension after multiple reconditioning can not meet sealing will Ask, then need valve base of safety valve sealing surface is machined out.
The situation of maintenance relief valve is as follows both at home and abroad at present:
1. effectively cannot fix relief valve in workshop breakdown maintenance, lead to relief valve disintegration, assembling extremely difficult, or even The security incident generation that larger caliber valve is toppled in disintegration and assembling process and injured operating personnel by a crashing object occurs.
Note:Its weight of relief valve that bore is more than DN250 is above 200Kg greatly, highly more than 1.5 meters.
2. sealing surface of safety valve lapping mode is to carry out hand lapping with grinding flat plate, and this operating type efficiency is low, work Industry personnel labor intensity is big;
For example:The relief valve that one entablature footpath is DN200, valve base sealing surface damage is serious, hand lapping valve element and valve seat are close The time of front cover often will exceed 4 hours, and an operating personnel at most can only repair 2 to 3 relief valve daily.
3. relief valve repair quality is often related to operating personnel proficiency level, and relief valve maintenance " disposable qualification rate " is no Method effectively improves, and leads to batch to do over again and have a strong impact on maintenance progress.
4. larger defect in valve base of safety valve needs to need special lathe and must make special frock during machining Fixture fixed valve, this mode is costly and maintenance cycle is long.
In view of drawbacks described above, be badly in need of design a kind of can stable holding relief valve device, realize maintenance and verifying function collection One-tenthization and automatization.
Content of the invention
The technical problem to be solved is:There is provided a kind of can stable holding relief valve device.
For solving above-mentioned technical problem, the technical scheme is that:
A kind of can stable holding relief valve device, it includes hoistable platform and relief valve fixture, wherein said lifting put down Platform includes the bottom and the top being oppositely arranged with bottom for being attached on ground, and it is flat that described relief valve fixture is installed on lifting The top of platform, described relief valve fixture is used for gripping relief valve, described relief valve fixture include horizontally disposed mounting disc, Three hold assemblies being arranged in mounting disc and being vertically arranged, described three hold assemblies are equal along the circumferencial direction of mounting disc Even distribution, the angle that each hold assembly connects the mounting disc center of circle with adjacent another hold assembly is 120 °, each hold assembly Including can be along pawling that radial direction moves, each hold assembly also includes the pressure for pushing down relief valve in above-below direction Pawl.
Compared with prior art, the present invention has the beneficial effect that:Due to relief valve fixture include horizontally disposed upper and lower The paw of relief valve is pushed down in direction, so that relief valve is hung directly from the clamping device of vertical vee-block compared to existing technology, Achieve multiple directions clamping, thus clamping is more stable.
