Abstract
The utility model discloses a novel valve core which is composed of a valve rod, a sealing ring and a valve cap. The valve rod is a cylinder, the sealing ring is arranged between the valve rod and the valve cap, the width of the sealing ring is 3mm, and an angle formed by the seal ring 2 and the valve cap is 90 degrees. The valve core is made of duplex stainless steel materials which are high in strength and resistant to intergranular corrosion and chloride stress corrosion. The novel valve core has the advantages of being high in processing accuracy, good in sealing effect and resistant to corrosion.
Description
Technical field
The utility model belongs to high-pressure service pump valve fitment field, relates in particular to a kind of novel spool.
Background technique
At present, the domestic and international high-pressure service pump that uses of high-pressure high-flow pump valve system, its life-span is short, noise is big, volume is big, fragile.And the inner spool machining accuracy height of external pump valve body, the domestic spool that oneself generates, poor sealing performance, its difficult technique is to guarantee.
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, is improved to 3mm at the ring bodies of spool face, and bonnet bottom angle is improved to 90 ° novel spool.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme:
A kind of novel spool is made up of valve rod, seal ring and bonnet, and described valve rod is a cylindrical body, and said seal ring is arranged in the middle of valve rod and the bonnet, and the width of said seal ring is 3mm, and the angle of described seal ring and bonnet is 90 °.
The utility model compared with prior art has significant advantage and beneficial effect:
Said spool adopts the two-phase stainless steel of intensity height and intergranular corrosion resistance and the corrosion of anti-chloride stress cracking; Precision process processing, original seal spool ring is 4mm, the angle of seal spool ring and bonnet is 80 °; Through technological improvement and production debugging for many years; Change the seal spool ring into 3mm, its angle changes 90 ° into, and sealability is better.
Description of drawings
Fig. 1 is the structural representation of a kind of novel spool of the utility model.
Wherein: 1-valve rod, 2-seal ring, 3-bonnet.
Embodiment
As shown in Figure 1: a kind of novel spool; Be made up of valve rod 1, seal ring 2 and bonnet 3, described valve rod 1 is a cylindrical body, and it is middle with bonnet 3 that said seal ring 2 is arranged on valve rod 1; The width of said seal ring 2 is 3mm, and described seal ring 2 is 90 ° with the angle of bonnet 3.
The said spool of the utility model adopts the two-phase stainless steel of intensity height and intergranular corrosion resistance and the corrosion of anti-chloride stress cracking.
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.
