Description
Technical field
The utility model relates to a kind of shuttle valve structure, especially relates to a kind of New Low Voltage shuttle valve.
Background technique
Shuttle valve belongs to straight stroke valve, is that valve body and final controlling element unite two into one the valve of body.Its advantage volume is little, easy for installation, adds the particularity of internal piston structure, makes pressure medium almost not have more resistance to disturb to piston, thus realizes snap switch, the one's best quality that crushing is little.
At present, shuttle valve generally adopts board-like, the tubular type mounting structure of plug-in type structure or band valve body, and their shortcoming is that volume is large, price.Thus it is simple to design a kind of structure, shuttle valve structure easy to use is very necessary.For this problem, this case produces thus.
Model utility content
Technical problem to be solved in the utility model provides a kind of New Low Voltage shuttle valve, and not only structure is simple, easy to use for it, and can the function of shuttle valve, thus is convenient for people to routine use.
In order to realize this object, the technical solution of the utility model is: a kind of New Low Voltage shuttle valve, comprise valve body, in described valve body, plug-in opening is set, described plug-in opening is communicated with at least three passages respectively and hydraulic pressure is blocked up, with the steel ball that can carry out moving left and right in described plug-in opening, described hydraulic pressure upper coupling of blocking up is combined with hydraulic pressure plug.
Further improvement as technique scheme:
According to embodiment of the present utility model, described passage comprises passage a, passage b and passage c, and described passage a and described plug-in opening joint are provided with the first cone mouth, and described first cone mouth can make described steel ball be adjacent to the described passage a of sealing further.
According to embodiment of the present utility model, described hydraulic pressure plug is provided with the second cone mouth, when described hydraulic pressure plug mates with described valve body, described second cone mouth can be through with described passage b.
According to embodiment of the present utility model, described hydraulic pressure plug is arranged the seal ring being used for sealed valve body.
According to embodiment of the present utility model, described diameter of the steel ball is less than or equal to plug-in opening width.
According to embodiment of the present utility model, described first cone mouth and described second cone mouth place are provided with pad.
According to embodiment of the present utility model, described hydraulic pressure plug side is provided with some triangular grooves.
Compared with prior art, the beneficial effects of the utility model are by being reasonably arranged in valve body by steel ball, utilize the pressure oil of different passage to promote about steel ball realize shuttle valve function.Secondly the setting of cone mouth and cone mouth Upper gasket is more conducive to the Seal and open to passage.
Accompanying drawing explanation
Fig. 1 is the utility model low pressure shuttle valve structure assembling schematic diagram;
Fig. 2 is the structure sectional view of hydraulic pressure plug in the utility model;
Fig. 3 is the structure sectional view of valve body in the utility model;
In figure: 1, steel ball; 2, valve body; 3, seal ring; 4, hydraulic pressure plug; 5, plug-in opening; 6, hydraulic pressure is blocked up.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in the figure, the New Low Voltage shuttle valve of the present embodiment, comprise valve body 2, according to the requirement machining hole of plug-in opening on valve body 2, namely arrange plug-in opening 5 in valve body 2, plug-in opening 5 is communicated with at least three passages respectively and hydraulic pressure blocks up 6, with the steel ball 1 that can carry out moving left and right in plug-in opening 5, hydraulic pressure coupling on 6 of blocking up is combined with hydraulic pressure plug 4, and hydraulic pressure plug 4 selects general G1/8 " hydraulic pressure plug.
Further, passage comprises passage a, passage b and passage c, and passage a and plug-in opening 5 joint are provided with the first cone mouth, and the first cone mouth can make steel ball 1 be adjacent to sealing channel a further.
Further, the screwed hydraulic pressure plug 4 of counter-lateral quadrents is processed, and namely plug 4 front end is provided with the second cone mouth, when hydraulic pressure plug 4 mates with valve body 2, the second cone mouth can by the pipeline of plug inside and passage b through.
Further, hydraulic pressure plug 4 is arranged the seal ring 3 being used for sealed valve body.Seal ring can ensure that valve inner fluid does not ooze out outside valve when oil circuit is connected.
Further, steel ball 1 diameter is less than or equal to plug-in opening 5 width.Steel ball equals plug-in opening 5 width in the present embodiment, thus improves the sealability to passway.
Further, the first cone mouth and the second cone mouth place are provided with pad.In the present embodiment pad is set according to the needs of steel ball, pad fits in the first cone mouth and the second cone mouth, avoid clashing into cone mouth for a long time when promoting about steel ball is by pressure oil and cause damage or distortion, and more effectively improve plugging effect when steel ball is butted on pad mutually.
Further, hydraulic pressure plug side is provided with some triangular grooves.
Embodiment: when a passway in valve body has pressure oil to carry to plug-in opening direction, steel ball 1 promotes by pressure oil to the right, the second cone mouth on plug 4 blocked by steel ball 1 after pushing up plug 4, a passage and c passage are connected, a passage and b passage and c passage and b passage all obstructed; When on valve body, b mouth has pressure oil to carry to plug-in opening direction, promoted to the left by steel ball 1, steel ball 1 blocks the first cone mouth on valve body 2 after pushing up valve body a passway, such that b is maritime to be connected with c passage, b passage and a passage and c passage and a passage all obstructed, thus realize shuttle valve function.
Specifically can implement in a variety of forms due to the utility model and not depart from spirit or the essence of model utility, so be to be understood that, above-described embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in claim of enclosing, therefore fall into whole change in claim or its equivalent scope and remodeling and all should be claim of enclosing and contained.
