Description
Technical field
The utility model belongs to explosion-proof valve, refers to a kind of oil cylinder of dumper explosion-proof valve for hydraulic jack especially.
Background technique
In self-unloading vehicle hydraulic system, for preventing the oil inlet pipe of connecting fluid compressing cylinder from causing hydraulic oil to leak because of overpressure failure, the load compartment of dumping car is caused to decline suddenly and major accident occurs.Usually need to assemble explosion-proof valve on the filler opening of connecting fluid compressing cylinder, the patent No. is disclose a kind of oil cylinder explosion-proof valve in the utility model patent of 201220361192.5, and main structure is that the hydraulic fluid port of cylinder body is built with explosion-proof valve; Explosion-proof valve is made up of swivel nut with holes, valve seat, spring, position limit pin, guiding valve; Guiding valve can kink be in the hole of valve seat up or down, and described guiding valve is the shell-like of interior sky, and its jacket wall radial direction has breach, breach has oil groove, and position limit pin is contained in the hole of valve seat, and is inserted in the breach on guiding valve jacket wall, spring one end withstands guiding valve, and the other end withstands swivel nut with holes.The subject matter that above-mentioned prior art exists is as follows: one is that fluid passage exists right-angle bending in guiding valve bottom, and be subject to the restriction of structural strength, the oil groove area increase that guiding valve jacket wall radial direction has is very limited, the larger pressure loss can be there is in hydraulic oil in the process by above-mentioned dog leg piping, the pressure loss is crossed conference and is caused energy loss, part pressure energy is converted into heat energy, and the rising of temperature causes hydraulic oil flow velocity to reduce, and then makes cylinder action slow.Two is adopt the slide core type clearance seal being agent structure with guiding valve, valve seat, and easily produce jam when the granule dirt in hydraulic oil enters seal clearance, long-time use easily causes explosion prevention function to lose efficacy.
Model utility content
The purpose of this utility model is to provide a kind of good antifouling effect, fluid passage oil cylinder of dumper explosion-proof valve smoothly.
Overall technology design of the present utility model is:
Oil cylinder of dumper explosion-proof valve, comprises valve body, to be opened on valve body and to pass through oil inlet P, the oil outlet A of oily channel connection; Cross oily passage and be a setting vertically and the luminal structure of middle part reducing, the axis of guide is arranged at its inside along crossing oily passage axis, the tapering dish of axis of guide front end assembling is adaptive with the reducing bulge lower end mouth crossing oily passage, the axis of guide, through pilot hole and valve interior wall axial sliding fit, the axis of guide between tapering dish and align member is set with Returnning spring.
Concrete technology contents of the present utility model also has:
For ensureing the smooth and easy of oily passage, meeting the leading role of pilot hole to the axis of guide simultaneously, preferred embodiment, the valve interior wall outside described pilot hole offering oil-through hole.
For ensureing the circulation that hydraulic oil is uniform and stable, more preferred technical implementation way is that described oil-through hole is in valve interior wall spaced at equal angles around.
For ensureing the axis of guide sliding axially in pilot hole, make it not deviate from pilot hole, preferably and comparatively common technique implementation is that described axis of guide rear portion is the end cap of a bulging, and the external diameter of this end cap is greater than the internal diameter of pilot hole simultaneously.Can it is evident that, this structure can also adopt the multiple technologies implementations such as locating stud, does not all depart from technical spirit of the present utility model.
Realize being connected for ease of valve body and cylinder installation seat, preferred technical implementation way is, described valve body offers mounting hole.
For ensureing the reliable and firm of assembling, meet uniform force, more preferred technical implementation way is that described mounting hole is symmetrical on valve body simultaneously.
Technological progress acquired by the utility model is:
1, reducing of the present utility model is crossed oily passage and is linearly distributed, and without the change of obvious sectional shape and area, running of hydraulic power oil is smooth and easy, and the pressure loss is little.
2, the varying diameter portion adopting tapering dish and reducing to cross oily passage is the tapering linear sealing of agent structure, and stain resistance is strong, and sealing reliability is high, and long-time operational failure rate is low.
Be provided with mounting interface by pipe fitting with oil inlet P, oil outlet A when 3, installing to realize being threaded, or adopt screw to realize board-like connection through mounting hole and cylinder installation seat, mounting type is versatile and flexible.
4, adopt exterior mode, be convenient to the maintenance of installation and component.
