Description
Technical field
The present invention relates to a kind of reduction valve, especially
a kind of fluid power reduction valve.
Background technique
Because the requirement of industrial automation level improves constantly, on the one hand the use amount of fluid power reduction valve is got more and more, also more and more higher to the control overflow of fluid power reduction valve on the other hand, become increasingly complex, so the design of fluid power reduction valve in electrical control is also in continuous renewal, along with the progress of science and technology and the popularization and application of computer
novel, various electric controling mode will constantly occur, to the consideration of fluid power reduction valve overall control aspect, answer the control mode of attentional selection fluid power reduction valve.
Summary of the invention
The object of the present invention is to provide
a kind of fluid power reduction valve, to solve the problem proposed in above-mentioned background technology.
The object of the invention is to be achieved by following technical proposals:
a kind of fluid power reduction valve, comprise locating stud, supporting frame, valve body, valve rod, spring, bindiny mechanism, positioning block, nut, fastening screw trip bolt; Described valve rod one end arranges supporting frame and supporting frame side arranges locating stud; Described locating stud is through valve inner and locating stud side arranges supporting frame; Described valve rod one end linking springs and spring outwards arranges bindiny mechanism; Described spring one end connects positioning block and positioning block is installed on bindiny mechanism inside; Described bindiny mechanism one end attaching nut and fastening screw trip bolt is installed on valve body one end.
Further, described nut is installed on bindiny mechanism inside.
Further, support frame as described above one end connects valve rod and supporting frame is positioned at valve inner.
Further, described both ends of the spring connects valve rod and positioning block respectively.
Further, described fastening screw trip bolt be T-type structure and fastening screw trip bolt through valve inner.
Compared with prior art, the invention has the beneficial effects as follows this
invent a kind of fluid power reduction valve, this invention physique structure is comparatively simple, and anufacturability is better, can be used on looped network pipeline that medium flow to two directions, that is medium flow to unrestricted, and start with close needed for moment less, effectively saved manufacturing cost.
Accompanying drawing explanation
fig. 1it is positive effect of the present invention
figure;
in figure: 1, locating stud; 2, supporting frame; 3, valve body; 4, valve rod; 5, spring; 6, bindiny mechanism; 7, positioning block; 8, nut; 9, fastening screw trip bolt.
Embodiment
Below in conjunction with in the embodiment of the present invention
accompanying drawingtechnological scheme in the embodiment of the present invention is clearly and completely described; obviously; described embodiment is only the present invention's part embodiment; instead of whole embodiments; based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
as Fig. 1shown in, the invention discloses
a kind of fluid power reduction valve, comprise locating stud 1, supporting frame 2, valve body 3, valve rod 4, spring 5, bindiny mechanism 6, positioning block 7, nut 8, fastening screw trip bolt 9; Described valve rod 3 one end arranges supporting frame 2 and supporting frame 2 side arranges locating stud 1; Described locating stud 1 is through valve body 3 inside and locating stud 1 side arranges supporting frame 2; Described valve rod 4 one end linking springs 5 and spring 5 arranged outside bindiny mechanism 6; Described spring 5 one end connects positioning block 7 and positioning block 7 is installed on bindiny mechanism 6 inside; Described bindiny mechanism 6 one end attaching nut 8 and fastening screw trip bolt 9 is installed on valve body 3 one end; It is inner that described nut 8 is installed on bindiny mechanism 6; Support frame as described above 2 one end connects valve rod 4 and supporting frame 2 is positioned at valve body 3 inside; Described spring 5 two ends connect valve rod 4 and positioning block 7 respectively; Described fastening screw trip bolt 9 is T-type structure and fastening screw trip bolt 9 is inner through valve body 3.
In use, valve rod overcomes spring pressure and moves to right, when pressure reaches certain value in the present invention, opening is there is between valve rod and valve body, along with the increase opening of pressure increases, pipeline inner pressure reduces, under the action of the spring, valve rod moves to left, opening reduces, and the unlatching size variation sending out mouth makes pressure maintain balance, the variable effect rotating speed of engine throttle, send out after mouth is opened and start again to close because pressure reduces, cause the change of pressure.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Should not any by claim
accompanying drawingmark is considered as the claim involved by restriction.
In addition, although should be appreciated that this specification is described according to mode of execution, not each mode of execution only comprises one
independenttechnological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
