Abstract

The utility model relates to a dismounting device and belongs to the technical field of vehicle component auxiliary equipment. The dismounting device comprises a mounting base and a handle connected to the mounting base through a rotary shaft. The handle comprises a movable pin which is located on a U-shaped opening in one end of the handle, and a T-shaped groove is formed in the position, opposite to the U-shaped opening of the handle, of the mounting base. When the dismounting device works, a valve body of a safety valve and a valve cover of the safety valve are clamped into the U-shaped opening and the T-shaped groove respectively. According to the dismounting device, due to the fact that the movable pin arranged in the U-shaped opening of the handle and the T-shaped groove structure of the mounting base are adopted, the valve body and a valve seat of the safety valve to be dismounted are fixed, the valve body and the valve seat of the safety valve are separated easily through rotation of the handle and the lever principle, and therefore the beneficial effect that the safety valve is rapidly dismounted is achieved.

Description

Dismounting device

Technical field

The utility model belongs to vehicle component supplementary equipment technical field, relates in particular to a kind of dismounting device of deadweight safety valve.

Background technique

A kind of safety protection valve of deadweight safety valve; its open-shut device is subjected to be in normally off under the External Force Acting; pressure medium in equipment or pipeline raises, and automatically opens when surpassing specified value, prevents that by discharge medium outside system pressure medium surpasses specified value in pipeline or the equipment.Safety valve belongs to the self-acting valve class, is mainly used on boiler, pressurized container and the pipeline, and pilot pressure is no more than specified value, and personal safety and equipment have been moved important protective action.

The integrated hydraulic safety valve is little because of volume, and valve body and valve seat are interference fit, when needs are taken maintenance apart, often is difficult to realize, adopts the method for knocking, even makes valve body impaired serious.

The model utility content

For above-mentioned technical problem, the utility model provides a kind of dismounting device of quick-detachment integrated hydraulic safety valve.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of dismounting device, comprise fitting seat and be connected to handle on the fitting seat by rotating shaft, described handle comprises loose pin, described loose pin is positioned on the U-shaped mouth of handle one end, and position relative with the U-shaped mouth of handle on described fitting seat has T-shaped groove, and valve body of safety valve, valve gap are stuck in described U-shaped mouth and the T-shaped groove during work.

The utility model dismounting device, employing be located at handle on U-shaped mouthful loose pin and the T-shaped groove structure of fitting seat the valve body of safety valve to be removed and valve seat are fixed respectively, utilize lever principle, make valve body of safety valve and valve seat easily realize disintegrating by handle with sleeve, reach the beneficial effect of quick-detachment safety valve.

Description of drawings

Fig. 1 is the utility model dismounting device cross-sectional view;

Fig. 2 is A among Fig. 1-A generalized section.

Embodiment

Below in conjunction with accompanying drawing the utility model is made and to be further specified.

As shown in the figure, the utility model dismounting device comprises handle 1, rotating shaft 2, fitting seat 4 and loose pin 5, handle 1 is connected on the fitting seat 4 by rotating shaft 2, it is U-shaped mouthful that the end of handle 1 is processed with, and as preferably, rotating shaft is positioned at U-shaped mouthful of handle next-door neighbour's a end, loose pin is positioned on the U-shaped mouth of handle, as preferably, loose pin 5 is installed on the U-shaped mouthful of relative two sides, and position relative with U-shaped mouthful of handle on fitting seat 4 has T-shaped groove.

During work, special-purpose T-slot on the fitting seat, safety valve to be removed 3 location can be clamped in the blind nut seal groove place of safety valve, then handle with sleeve 1, makes loose pin 5 be in the valve body of chucking safety valve to be removed, firmly rotate handle 1, as fulcrum, lever principle has increased safety valve solution muscle power by rotating shaft 2, overcome interference fit frictional force between valve body and the valve gap, safety valve is dismantled quickly and easily come.

Above embodiment's description is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
