Abstract
The utility model discloses a novel piston which includes a piston body, wherein the inside of the piston body is a hollow structure. According to the novel piston, due to the fact that the inside of the piston body is hollow, the weight of the piston is reduced, the abrasion of the sealing of the lower end of the piston when the piston works horizontally is avoided, and the damage of the piston due to the direct friction of the piston and a cylinder body is avoided.
Description
Technical field
The utility model relates to a kind of novel piston.
Background technique
The pressure of used to synthesize artificial diamond mainly transmits by piston in cubic hinge press, and the present piston of doing is all solid construction, is that steel process by forging.Along with the continuous expansion of cubic hinge press cavity, the weight of piston self is also more and more heavier.When if piston is horizontal positioned, the effect of hydraulic coupling is not only born in the sealing of piston lower end, also bears the gravity of piston self simultaneously, be easy to make the bad seals of piston lower end, cause the contact of piston or cylinder body, the friction between metal occurs, cause Remedy for Piston Damage.
The model utility content
The purpose of this utility model is to provide the little novel piston of a kind of weight, improves the piston performance.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of novel piston comprises piston only, and described piston only inside is hollow-core construction.
Described hollow-core construction is provided with opening at the large end of piston only, and described opening is tightly connected by plug.
Be provided with sealing configuration between described plug and piston only.
Described sealing configuration is seal ring.
In the utility model, piston only inside is hollow, has just alleviated the weight of himself, and in the time of the piston horizontal operation can not occurring, its lower end Sealing Phenomenon that can wear and tear, can not cause piston self and cylinder body direct friction to cause Remedy for Piston Damage yet.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of novel piston comprises piston only 1, and described piston only 1 inside is hollow-core construction 2.Described hollow-core construction 2 is provided with opening at the large end of piston only, and described opening is tightly connected by plug 3.Be provided with sealing configuration 4 between described plug 3 and piston only 1.Described sealing configuration 4 is seal ring.
In the utility model, piston only 1 inside is processed into hollow, the back compresses with plug 3, seals with seal ring between plug 3 and piston only 1.Be that the large end of piston is stressed because piston is stressed, so plug 3 is pressed on piston only 1, seal by seal ring, the fluid of the large end of piston can not entered in the piston hollo chamber.
Claims (4)
1. a novel piston, comprise piston only, it is characterized in that, described piston only inside is hollow-core construction.
2. novel piston as claimed in claim 1, is characterized in that, described hollow-core construction is provided with opening at the large end of piston only, and described opening is tightly connected by plug.
3. novel piston as claimed in claim 2, is characterized in that, is provided with sealing configuration between described plug and piston only.
4. novel piston as claimed in claim 3, is characterized in that, described sealing configuration is seal ring.
