Abstract
The utility model relates to a novel sealing element of high-pressure fluid and the structure is laminated by a Y-shaped sealing element, a pressure ring and a retainer ring. The device adjusts the tightness according to the pressure of the fluid, well solves the gas leakage and fluid leakage problems of a recoil system of large-sized artillery and prolongs service life thereof and improves tactical qualities of the artillery. The utility model simplifies the variety of the sealing element and is convenient for storage and supply of elements; meanwhile, the utility model can be promoted and applied to sealing parts of various civilian high-pressure fluids.
Description
The utility model relates to a kind of seal arrangement, specifically a kind of new type sealing device that high-pressure liquid is sealed.
The recoil mechanism of cannon is to adopt gas or liquid to carry out the absorption of kick, after absorbing kick, promptly become pressurized gas or liquid, this has just proposed very high sealing requirements to the seal arrangement in the recoil mechanism, uses continuously to ensure the normal of cannon.Large caliber gun comprises the recoil mechanism of self-propelled gun at present, mostly employed seal arrangement is the tight plunger member that employing ox-hide and asbestos rope are made, and this sealing configuration is in use because poorly sealed, often leak air, the phenomenon of leakage, influenced the combat performance of cannon.In addition, this tight plunger member also has complex manufacturing technology, and yield rate is lower, and the more high many unfavorable factors of cost exist.
The purpose of this utility model is a kind of to pressurized gas or liquid can effectively seal and sealability improves with the increase of pressure cannon recoil mechanism new type sealing element with regard to providing, to overcome the deficiency that existing seal arrangement exists, improve the combat performance of cannon.
The utility model is achieved in that Sealing coincides by y-type seal ring, at the pressure ring of y-type seal ring front portion and the back-up ring at the y-type seal ring rear portion and forms.Under the snap of high-pressure liquid, pressure ring is pressed towards y-type seal ring, makes the sealing strip expansion of y-type seal ring, thereby the sealability of having regulated seal ring is guaranteed seal ring realization sealing reliably.Back-up ring is played a supporting role to y-type seal ring, enables to adapt to the impact of high-pressure liquid.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1, Fig. 2 are the structural representations that the utility model is installed and used in two kinds of similar devices.
Shown in accompanying drawing, the utility model is coincided by y-type seal ring 4, pressure ring 3 and back-up ring 5 threes and forms.There is a circle groove 41 in the front of y-type seal ring 4, and the notch both sides in seal ring cross section form height lip 42,43, and the fixed edge of seal ring is high lip 42, and the movable sealing limit is low lip 43.In conjunction with the accompanying drawings as seen, the interior bar 1 among Fig. 1 is a fixing rod, and urceolus 2 is a quill, thereby the interior edge of y-type seal ring 4 is the seal ring fixed edge, is high lip 42; The seal ring outer is the movable sealing limit, is low lip 43.Fig. 1 is uprightly placed, make pressure ring 3 last, seal ring 4 is following, and this moment, the cross section, left side of seal ring 4 formed alphabetical Y shape, so claim that seal ring 4 is a y-type seal ring.Fig. 2 is the device form opposite with Fig. 1, and promptly interior bar 1 is a motion bar, and urceolus 2 is stationary magazine creels.Also opposite with Fig. 1 of the fixed edge of y-type seal ring 4 and movable sealing limit, thereby the cross section, left side of seal ring 4 so just forms " anti-Y type ", but also is referred to as y-type seal ring.
The fin that pressure ring 3 one side relative with y-type seal ring in this new type sealing element has a circle to match with o-ring groove 41.By accompanying drawing as seen, when pressurized gas or liquid 6 are instantaneous when pressing to pressure ring 3, on the pressure ring 3 one circle fin promptly is pressed in the groove 41 of y-type seal ring 4, make low lip 43 on the y-type seal ring 4 press to the inwall (Fig. 1) of the urceolus 2 that the movable sealing limit reclined or the outer wall (Fig. 2) of interior bar 1, the sealability of Sealing is improved, and the pressure of high-pressure liquid 6 is big more, then pressure ring 3 is pressed into deeply more, the low lip 43 of y-type seal ring 4 is just closely pressed to sealing surface, the sealability of having regulated Sealing thus more.
Have a circle draw-in groove along the movable sealing limit at the back side of y-type seal ring 4 in the accompanying drawing, the relative contact position of back-up ring 5 has a circle card rib 51.Card rib 51 snaps in the draw-in groove, makes back-up ring 5 and Y type Sealing 4 keep relative fixed.The effect of back-up ring 5 is to support y-type seal ring 4, increase the intensity of y-type seal ring 4,, both can guarantee that y-type seal ring 4 did not produce the phenomenon of gas leakage, leakage because of deformation with the impact of tolerance high-pressure liquid 6, can improve the working life of Sealing again, guarantee that the normal continuously of cannon uses.
The utility model can be regulated sealability according to hydrodynamic pressure, has solved gas leakage, the phenomenon of leakage of large-scale cannon recoil mechanism well, has prolonged the working life of cannon recoil mechanism, can improve the tactical qualities of cannon thus.The utility model has been simplified cannon Sealing kind, is convenient to the storage supply of part, also can promote the use of civilian various high-pressure liquid sealings position simultaneously.
Claims (4)
1, a kind of cannon recoil mechanism new type sealing element is characterized in that the sealing part coincides by y-type seal ring (4), at the pressure ring (3) of y-type seal ring front portion and the back-up ring (5) at the y-type seal ring rear portion to form.
2, new type sealing element according to claim 1, there is a circle groove (41) in the front that it is characterized in that y-type seal ring (4), the notch both sides in seal ring cross section form height lip (42,43), and the fixed edge of seal ring is high lip (42), and the movable sealing limit is low lip (43).
