Abstract
A threaded inserted type manual unloading valve comprises a threaded connection sleeve assembly, a valve sleeve assembly and an unloading operation assembly. A hollow push rod is arranged in a threaded connection sleeve. Meanwhile, a support frame is arranged on the outer side of the threaded connection sleeve, and a plurality of support points are arranged at the juncture of the threaded connection sleeve and the lower portion of the support frame. The support frame is fixed on the outer side of the threaded connection sleeve through a tightening nut and a locking washer. One side of the support frame is provided with a plug pin seat used as a pivot, and a protruding rod is mounted on the plug pin seat. A protruding surface on the protruding side of the protruding rod is right opposite to the top end of the hollow push rod. The threaded inserted type manual unloading valve is simple in technology, convenient to process, easy to assemble and stable in unloading operation control pressure.
Description
Technical field
The utility model relates to the hydrovalve class component, is specially a kind of screw thread inserting type Manual relief valve.
Background technique
Manual relief valve is a kind of pressure controlled valve, often be applied in the hydraulic system pipeline, play the effect of pressure release, traditional hydrovalve mainly contains two kinds of board-like and overlappings, yet that these two kinds of traditional valve arrangements all exist volume is relatively large, the defective that weight is heavier, simultaneously, the valve body processing technology is complicated, and fabricating cost is high, installation, use and coherent detection are dismantled also and inconvenience, have greatly limited its using scope.
Yet; the Manual relief valve mechanism of existing screw thread inserting type has many unreasonable; be not suitable with the needs that modern production is used; for example its inner push rod and spool, for convenient, the two all separates in the production assembly process; as daily consumption larger spool consumptive material structure all; the operation of the two the mode of separately assembling just seems very inconvenient, and also easy Manual relief valve is limit because of self structure and application, usually can cause the loosening of locking mechanism.Simultaneously, because traditional operating handle supporting frame is fixed in to be threaded and puts, the power that all operating handles are received all will be threaded connection cover and be delivered on the installation screw thread, if things go on like this will certainly become flexible or destroy screw thread and related components.
The model utility content
The technical problem that the utility model solves is to provide a kind of screw thread inserting type Manual relief valve, this Manual relief valve adopts the formula that is threaded into of convenient operation that valve body is installed, compact structure, low cost of manufacture, be applicable to the needs of modern production, can be in order to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of screw thread inserting type Manual relief valve, comprise the grip assembly that is threaded, valve pocket assembly and off-load operating component, wherein, be provided with push rod in the threaded connecting sleeve, this push rod is two little rank bar structures of cross section, large, lower rank, cross section, rank on, the crossover position place of its two stage structure is provided with a cross section greater than the combined openings back-up ring in cross section, upper rank, and the lower rank bar of two rank push rods partly overlaps Returnning spring is arranged, and is threaded connection in its underpart on the spool of valve pocket assembly; Simultaneously, also be provided with a supporting frame in the outside of threaded connecting sleeve, and be provided with some strong points in the position, boundary of threaded connecting sleeve and supporting frame bottom; Support frame as described above is fixed on the outside of threaded connecting sleeve by piecing together jack panel and lock washer, one side has plug housing as fulcrum, and one nose bar is installed as operating stem at plug housing, and the protruding convex surface to a side of this operating stem is over against the top of hollow push rod.
In the utility model, stressed evenly for the top that guarantees hollow push rod, anti-throw-out lever is stuck in loading process, and the hollow push rod front end is set to sphere or arc shaped surface.
In the utility model, the top of described Returnning spring is fitted on the lower surface split washer of push rod, then fits with the valve pocket top of valve pocket assembly in the bottom.
In the utility model, adopt back-up ring to add that the combination seal mode of O type circle seals between described each critical activity plug connector.
Beneficial effect: the utility model compact structure, spool and push rod separate when producing, and be easy to process, but then be combined as a whole convenient operation when assembling.And the Point of Strength of operating handle supporting frame directly can be discharged to by the strong point and install on the valve piece, can effectively protect screw thread and related components, simultaneously, can prevent effectively that link is loosening.
Description of drawings
Fig. 1 is the schematic representation of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Schematic representation referring to the preferred embodiment of a kind of screw thread inserting type Manual relief valve of Fig. 1, in the present embodiment, operating handle 2 one ends are equipped with to be held bulb 1 and is used for the easy-to-operat personnel and applies external force, and the other end then is fixed on the supporting frame 4 with common formation bracket assembly by latch 3; Push rod O type circle 6 and push rod back-up ring 5 are housed on the push rod 23.
During assembling, with combined openings back-up ring 19 and the Returnning spring 18 push rod 23 rear insertion valve pockets 14 of packing into, screw in immediately spool 10 and utilize screw thread 7 to connect, this moment, spool 10 lower ends were contacted with valve pocket potted line 11, the threaded connecting sleeve 20 of behind assembling maintenance O type circle 15, packing into, and the overcoat O type circle 16 of packing into simultaneously, valve pocket O type circle 13 and the 12 rear formation of the valve pocket back-up ring grip assembly that is threaded.In total process of assembling, the integrated package of first threaded connecting sleeve 20 assemblies being packed into is loaded onto bracket assembly subsequently, by four strong point 17 support limit, and utilizes and pieces together jack panel 22 compression lock washers 21, makes it fixed support on integrated package.
In use, pressure oil is filled with die cavity 9 through runner 8, this moment, the spool push-rod assembly kept static under the effect of spring 18, swivel lever is pressed to sphere 24, promote push rod and open spool, pressure oil can be through inner chamber 9 off-loads, and whole process operation is smooth, and are difficult for valve body and associated component thereof are caused damage.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof
