Fig. 1 is the structural representation of the utility model the first state;
Fig. 2 is the structural representation of the utility model the second state.
Embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand fully the purpose of this utility model, feature and effect.Obviously; described embodiment is a part of embodiment of the present utility model, rather than whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite of not paying creative work all belong to the scope that the utility model is protected.
With reference to Fig. 1, Fig. 2, reduction valve provided by the utility model is regulated locking framework, comprise reduction valve main body 1, this main body 1 is provided with the stand in channel 11 that is connected, and this goes out passage 12, stand in channel 11 is used for connecting the persistent pressure system, this stand in channel 11 and go out passage 12 common levels and align the straight line relation that is that arranges, at this stand in channel 11 and go out passage 12 and be connected with a return flow line 13, there is a turnout track 14 this return flow line 13 in addition interconnection, be provided with slidably sealing plug 2 in the turnout track 14, in this turnout track 14, be arranged with an adjustable column 3, and this adjustable column 3 is installed on the main body 1 by screw thread, suppress simultaneously the spring 4 of sealing plug 2 in the inner of adjustable column 3 connection one, the compressing so that sealing plug 2 is under pressure, press closely at turnout track 14 in stand in channel 11 on the top, go out the crossing of passage 12, mouth end with return flow line 13 seals simultaneously, and the crossover location relation by above-mentioned each passage, sealing plug 2 is when being subject to stand in channel 11 and going out the larger pressure of passage 12, can be back slide, thus so that return flow line 13 oral areas and stand in channel 11 and go out passage 12 and be connected together.
Usually for the ease of design, in preferred embodiments, turnout track 14 can be selected with stand in channel 11, go out passage 12 square crossings, is making infall have conical taper simultaneously, and the corresponding end of sealing plug 2 that makes is tapered, to cooperatively interact; Simultaneously return flow line 13 and turnout track 14 are intersected vertically, form the passage annexation; Under this structure, can be beneficial to the pressure influence that sealing plug 2 is subjected to stand in channel 11 and goes out passage 12, slip sub-fraction distance just can release return flow line 13.
The utility model when work, sealing plug 2 can stand in channel 11 and the interior pressure medium that goes out passage 12 be not more than spring 4 impose on its pressure the time, be positioned at original position, namely block the position of return flow line 13 so that normally voltage supply of valve, its state such as Fig. 1; And stand in channel 11 and go out medium in the passage 12 exert pressure greater than spring 4 to its exert pressure the time, compressing sealing plug 2 slides along turnout track 14 rollbacks, and then make return flow line 13 with stand in channel 11 and go out passage 12 and be connected, force unnecessary pressure 13 to draw off from the return flow line, reach decompression and pressure balanced purpose, its state such as Fig. 2.
In this external preferred version, turnout track 14 is from establishing internal thread, so that adjustable column 3 near middles are connected with turnout track 14 by screw thread; As long as rotate adjustable column 3, just can adjust it in the degree of depth of turnout track 14 under this structure, and then adjust the degree of compression of spring 4, to reach the effect of adjusting sealing plug 2 elastic pressures, as seen by this structure, can be convenient to arrange the flowing pressure that unloads that needs.
Can not slide after adjustable column 3 is adjusted in order to guarantee in addition, increase stability, can screw thread be set in turnout track 14 outer ends, one locking nut 5 is installed by this, is pushed down adjustable column 3 by this locking nut 5, like this after adjustable column 3 adjustings put in place, locking locking nut 5, just can lock adjustable column 3, make its fixing can't adjusting, thereby guarantee the stability of pressure.
In this external its further preferred version, be provided with raised step on the adjustable column 3, locking nut 5 has respective side and is pressed on this raised step, reaches preferably respective outer side edges relation, in order to guarantee that its lock ability prevents from getting loose, and press-fits pad 51 between locking nut 5 and the raised step; In order to guarantee sealing, prevent the leakage of turnout track 14 places in addition, can between the adjustable column 3 that is close to pad 51 and turnout track 14, seal ring 31 be set, and between adjustable column 3 hypomeres and turnout track 14, lower seal 31 be set.
The utility model in use, can be at stand in channel 11, go out between the passage 12 to be communicated with a measuring pressure passage 15, this measuring pressure passage 15 is connected with a pressure gauge 6, by pressure gauge 6, can measure stand in channel 11, go out the pressure of passage 12, thereby can be convenient to accurate pressure adjustment.
Therefore, because sealing plug 2 is subject to the pressure-acting of spring 4, by stand in channel 11, go out the pressure medium of passage 12 when being no more than its force value, sealing plug 2 can be blocked return flow line 13 all the time, and after surpassing certain pressure, sealing plug 2 can be pushed open, the medium of too much pressure is drawn off by return flow line 13, reach decompression; Can so that the force value that sets can be come accurate adjustment as required, possess good balance and can select by the pressure of 4 pairs of sealing plugs 2 of adjustable column 3 Regulation springs before use in addition, use very convenient reliable; And by locking nut 5, then can after adjustable column 3 is adjusted, reach and be locked preferably, guaranteed the stability that pressure arranges.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
