Description
Technical field
The utility model relates to a kind of one-way valve, particularly the structure of piston in one-way valve.
Background technique
At present, one-way valve generally comprises valve body, spring, piston, and valve body inside is provided with annular screens tooth, and spring one end is connected on annular screens tooth, and the other end is stuck in piston one end.But the quality comparation of described one-way valve piston is as above large, sensitivity is not high, and when the Driving force in the external world is not very large time, one-way valve is inoperative, for this reason, changes again the structure of piston.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the problem that the utility model solves is: piston mass is large, sensitivity is not high.
For solving above-mentioned technical problem, the utility model adopts following technological scheme:
An one-way valve for piston can be promoted fast, comprise valve body, spring, piston, seal ring; Described valve body inside is provided with the passage running through valve body two ends; Valve body comprises the first valve body and the second valve body; One end of described first valve body is embedded in one end of the second valve body, and one end that the first valve body embeds the second valve body is the little tapered opening of outer imperial palace; Described seal ring is fitted in tapered opening; Described second valve inner is provided with annular screens tooth; Described piston profile is round column structure and its inside is provided with cavity; Described piston has elasticity; Piston one end is the circular open with circular fold; The piston the other end is taper; The external side parallel of described taper is provided with taper sheath, and described taper sheath is fixed by link and taper; The circular fold cross-under of piston one end is in one end of spring; The taper sheath of the piston the other end and seal ring laminating; The other end of spring is stuck on annular screens tooth.
Further, described annular screens tooth is provided with limited impression, and described spring housing is connected on limited impression.
Further, the structure that described link is tapered; The outer surface of link and taper, the inner surface of taper sheath are vertical; The section of described link, taper, taper sheath linkage structure is I-shape construction.
The beneficial effects of the utility model are:
Internal piston is arranged in cavity structure, alleviates the quality of piston greatly.The circular open with circular fold is arranged in piston one end, and because piston has elasticity, so by circular fold cross-under on one end of spring, the cross section of such piston just reduces, and expands the cavity area of valve body inside simultaneously, increases its capacity.The piston the other end is arranged to taper, at the external side parallel of taper, taper sheath is set, taper sheath is fixed by link and taper, taper sheath and seal ring laminating, the taper that such structure makes piston directly and seal ring fit, the taper sheath utilizing link fixing and seal ring laminating, shorten the length of whole piston, alleviate whole quality.As above shorten the depth of section of piston, length and internal piston cavity, the quality of whole piston is alleviated greatly, increases valve body capacity simultaneously; Improve the sensitivity of piston.

Fig. 1 is overall structure sectional view of the present utility model.
Fig. 2 is the structure sectional view of piston in the utility model.
Fig. 3 is the enlarged view of linkage structure of spring and annular screens tooth, piston.
Embodiment
Below in conjunction with accompanying drawing, content of the present invention is described in further detail.
As shown in Figure 1, a kind of one-way valve that can promote piston fast, comprises valve body 1, spring 4, piston 3, seal ring 2.Described valve body 1 inside is provided with the passage 13 running through valve body two ends.Valve body 1 comprises the first valve body 12 and the second valve body 11.One end of described first valve body 12 is embedded in one end of the second valve body 11, and one end that the first valve body 12 embeds the second valve body 11 is the little tapered opening of outer imperial palace 121.Described seal ring 2 is fitted in tapered opening 121.Described second valve body 11 inside is provided with annular screens tooth 111.As shown in Figure 2, described piston 3 profile is round column structure and its inside is provided with cavity 31.Described piston 3 has elasticity.Piston 3 one end is the circular open with circular fold 32.Piston 3 the other end is taper 33.The external side parallel of described taper 33 is provided with taper sheath 34, and described taper sheath 34 is fixed by link 35 and taper 33.As shown in Figure 3, circular fold 32 cross-under of piston 3 one end is in one end of spring 4.As illustrated in fig. 1 and 2, the taper sheath 34 of the piston the other end and seal ring 2 are fitted.The other end of spring 4 is stuck on annular screens tooth 111.Further preferably, as shown in Figure 3, described annular screens tooth 111 is provided with limited impression 1111, and described spring 4 is socketed on limited impression 1111.Further, as shown in Figure 2, the structure that described link 35 is tapered.The outer surface of link 35 and taper 33, the inner surface of taper sheath 34 are vertical.The section of described link 35, taper 33, taper sheath 34 linkage structure is I-shape construction.Piston 3 inside is arranged in cavity 31 structure, alleviates the quality of piston 3 greatly.The circular open 36 with circular fold 32 is arranged in piston 3 one end, because piston 3 has elasticity, so by circular fold 32 cross-under on one end of spring 4, the cross section of such piston 3 just reduces, expand the cavity area of valve body 1 inside simultaneously, increase its capacity.Piston 3 the other end is arranged to taper 33, at the external side parallel of taper 33, taper sheath 34 is set, taper sheath 34 is fixed by link 35 and taper 33, taper sheath 34 and seal ring 2 are fitted, such structure make the taper 33 of piston 3 directly and seal ring 2 fit, utilize the fixing taper sheath 34 of link 35 and seal ring 2 to fit, shorten the length of whole piston 3, alleviate whole quality.As above shorten the depth of section of piston 3, length and piston 3 internal cavities 31, the quality of whole piston 3 is alleviated greatly, increases valve body 1 capacity simultaneously, improve the sensitivity of piston 3.
