Abstract

The utility model discloses a kind of fracturing pump valve core seal ring with pooling feature, comprise valve seat, spool, seal ring, it is characterized in that, described seal ring comprises body portion and epitaxial part, described epitaxial part is used for producing buffer space between spool and valve seat, be provided with the buffering suface contacted with valve seat outside described epitaxial part, fasten completely outside described epitaxial part inside structure and spool, described buffer space width is 1.8 ㎜.The utility model structure is simple, need not set up damping device, make seal ring have two kinds of functions simultaneously, both extended the working life of spool valve seat, and again saved manufacture cost.

Description

A kind of fracturing pump valve core seal ring with pooling feature
Technology neck with
The utility model relates to a kind of fracturing pump, particularly relates to a kind of fracturing pump spool, is specifically related to a kind of seal ring be arranged on fracturing pump spool.
Background technique
Existing valve core seal ring is for the gap between sealed valve core and valve pocket, but spool operationally, directly can clash into valve seat, cause spool and valve seat greatly to shorten working life, and because its structural particularity not easily installs damping device between spool and valve seat.Claimant is found by research, by seal ring being made to play the effect of buffering thickening suitable for seal ring, change structure, so both need not set up damping device, and can ensure that again spool did not directly clash into valve seat, extends the working life of spool, valve seat.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of seal ring with pooling feature.
For achieving the above object, the utility model provides a kind of fracturing pump valve core seal ring with pooling feature, comprise valve seat, spool, seal ring, it is characterized in that, described seal ring comprises body portion and epitaxial part, described epitaxial part is used for producing buffer space between spool and valve seat, is provided with the buffering suface contacted with valve seat outside described epitaxial part.
Further, fasten completely outside described epitaxial part inside structure and spool.
Further, described buffer space width is 1.8 ㎜.
The beneficial effects of the utility model are: the utility model structure is simple, need not set up damping device, make seal ring have two kinds of functions simultaneously, both extended the working life of spool valve seat, and again saved manufacture cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fracturing pump valve core seal ring embodiment of the utility model one one kinds with pooling feature.
Fig. 2 is that in Fig. 1, the amplification of A is schemed greatly.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See Fig. 1 to Fig. 2, a kind of fracturing pump valve core seal ring with pooling feature, comprise valve seat 1, spool 2, seal ring 3, described seal ring 3 comprises body portion 31 and epitaxial part 32, described body portion 31 seals for making spool 2 and valve pocket, described epitaxial part 32 for producing buffer space 4 between spool 2 and valve seat 1, and described buffer space 4 width is preferably 1.8 ㎜; Buffering suface 321 is provided with outside described epitaxial part 32; During use, buffering suface 321 contacts with valve seat; Fasten completely outside described epitaxial part inside structure and spool 2, make it in use not easily slide.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that ability and those of ordinary skill just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technology neck with middle technician according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
