Abstract
The utility model discloses a valve core and valve base structure of a reciprocation pump. The valve core and valve base structure comprises a valve core and a valve base, wherein the valve core has a solid structure and comprises a valve rod and a valve cap provided with a notch, the valve cap is matched with a rod-core cavity at the upper part of the valve seat, and the top part of the valve seat is provided with two circular holes. The valve core and valve base structure of the utility model has the advantages of high processing precision, good sealing effect, stable and reliable operation, and capability of adapting to requirements of higher pressure.
Description
Technical field
The utility model belongs to high-pressure service pump valve fitment field, relates in particular to a kind of spool and valve seat construction of reciprocating pump.
Background technique
At present, in the domestic existing technology, mostly spool and valve seat that the mechanical valve sealing is used are plane sealing, and shortcoming is: sealing effect is poor, and machining accuracy is low, can't satisfy more high pressure requirement, influences the working life of spool and valve seat.
The model utility content
The utility model problem to be solved is, overcomes the deficiency of existing technology, a kind of machining accuracy height, good sealing effect is provided, can adapts to the more spool and the valve seat construction of the reciprocating pump of high pressure requirement.
For realizing above-mentioned purpose; The utility model is realized through following technological scheme: a kind of spool of reciprocating pump and valve seat construction, form by spool and valve seat, wherein; Said spool is a solid construction; The bonnet that spool comprises valve rod and has notch, said bonnet cooperates with the post core chamber on the top of valve seat, and said valve seat top is provided with two circular holes.
Post core chamber in the said valve seat originally was a plane sealing, changed into pushing away at present and pulled out sealing, and pressure rating can be brought up to 150Mpa.
It is between the 1-10mm that said bonnet four sides respectively has width of rebate.
Said spool and valve seat adopt different steel manufacturings according to the character of fed sheet of a media with customer requirements, and anti-corrosive pump adopts the two phase stainless steel manufacturing.
The utility model compared with prior art has significant advantage and beneficial effect: spool adopts solid integrative-structure, and machining accuracy is high; The post core chamber on the valve seat and the angle of bonnet connection part are 90 °, good sealing effect; Employing pushes away pulls out sealing, can adapt to more high pressure requirement; Overall structure is simply used, stable working, reliable.

Fig. 4 is the plan view of the utility model valve seat.
Wherein: 1-valve seat, 2-spool, 3-post core chamber, 4-notch, 101-circular hole, 201-valve rod, 202-bonnet.
Embodiment
As depicted in figs. 1 and 2: a kind of spool of reciprocating pump and valve seat construction; Form by valve seat 1 and spool 2; Wherein, said spool 2 is a solid construction, the bonnet 202 that spool 2 comprises valve rod 201 and has notch; Said bonnet 202 cooperates with the post core chamber 3 on the top of valve seat 1, and said valve seat top is provided with two circular holes 101.
It is between the 1-10mm that said bonnet 202 four sides respectively have notch 4 width.
Said valve seat 1 and spool 2 adopt different steel manufacturings according to the character of fed sheet of a media with customer requirements, and anti-corrosive pump adopts the two phase stainless steel manufacturing.
The utility model is work like this:
Pressure fluid holds up bonnet in the inflow valve body of valve seat bottom, makes on the spool and moves, and the Returnning spring that is contained between fixed support and the Sealing is compressed; When the bonnet bottom does not have pressure fluid, under the effect of Returnning spring, valve core reset, the one-way valve group is closed.
What should explain at last is: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although the utility model book has carried out detailed explanation to the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of the spirit and the scope of model utility, and it all should be encompassed in the middle of the claim scope of the utility model.
