Abstract
The utility model discloses a temperature reducing and pressure reducing valve, which comprises a water spray pipe, a valve core, an inner sleeve, an outer sleeve, a valve rod and an adjusting sleeve, wherein the water spray pipe is positioned on the lower part; the valve core is sleeved on the upper part of the water spray pipe; the inner sleeve is sleeved outside the upper part of the valve core; the outer sleeve is sleeved outside the inner sleeve; the valve rod is inserted in the center of the valve core; the adjusting sleeve is positioned at the lower end of the outer sleeve; a disc spring is arranged between the valve rod and the inner sleeve; and at least one disc is arranged in the adjusting sleeve and on the upper part of the water spray pipe and is provided with an opening. The temperature reducing and pressure reducing valve has a simple structure, the erosion resistance is improved in the case of small opening, and further, the performance of the adjusting valve is greatly improved and the service life of the adjusting valve is greatly prolonged.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of pressure and temperature reducing valve.
Background technique
Existing pressure and temperature reducing valve is to comprise shower, the spool that is set in said shower top, the inner sleeve that is sheathed on said spool upper external that are positioned at the bottom, be sheathed on the outside outer sleeve of said inner sleeve, be inserted in the valve rod and the said regulating sleeve that is positioned at said outer sleeve lower end of said spool central authorities mostly, between said valve rod and the said inner sleeve dish spring is set.It is lower that but the shortcoming of such valve is an erosion resistibility, directly has influence on the performance and the working life of valve.
Summary of the invention
The utility model is accomplished in order to solve deficiency of the prior art; The purpose of the utility model provide a kind of simple in structure, when little aperture, promote erosion resistibility, and then improved the performance of this modulating valve valve and the pressure and temperature reducing valve in working life greatly.
A kind of pressure and temperature reducing valve of the utility model; Comprise shower, the spool that is set in said shower top, the inner sleeve that is sheathed on said spool upper external that are positioned at the bottom, be sheathed on the outside outer sleeve of said inner sleeve, be inserted in the valve rod and the said regulating sleeve that is positioned at said outer sleeve lower end of said spool central authorities; Between said valve rod and the said inner sleeve dish spring is set; It is characterized in that: be positioned at said shower top in the said regulating sleeve a slice disc at least is set, offer mouth on the said disc.
A kind of pressure and temperature reducing valve of the utility model can also be:
Be positioned in the said regulating sleeve at least two discs are set on the said shower.
Said each disc average level is provided with.
Said disc is through being bolted to the lower end of said outer sleeve, and said disc is positioned at said regulating sleeve interior surface.
The below that is positioned at said disc on the said regulating sleeve is around at least three grooves of said regulating sleeve circumference setting.
Said groove is a rectangle groove, and the height of said groove is greater than the width of said groove.
A kind of pressure and temperature reducing valve of the utility model is provided with a slice disc at least owing to be positioned at said shower top in the said regulating sleeve, offers mouth on the said disc.Like this, the advantage that has in terms of existing technologies is to have changed adjustable scope after disc is set, and has promoted erosion resistibility in little aperture, and the function of throttling step-down is more obvious, and provides more space.

Embodiment
Fig. 1 below in conjunction with accompanying drawing does further explain to a kind of pressure and temperature reducing valve of the utility model.
A kind of pressure and temperature reducing valve of the utility model; Please refer to Fig. 1; Comprise shower 1, the spool 7 that is set in said shower 1 top, the inner sleeve 4 that is sheathed on said spool 7 upper external that are positioned at the bottom, be sheathed on the outside outer sleeve 3 of said inner sleeve 4, be inserted in the valve rod 6 and the said regulating sleeve 8 that is positioned at said outer sleeve 3 lower ends of said spool 7 central authorities; Between said valve rod 6 and the said inner sleeve 4 dish spring 5 is set; Be positioned at said shower 1 top in the said regulating sleeve 8 a slice disc 2 at least is set, offer mouth 10 on the said disc 2.Like this; During use, water slug disc 2, the mouth 10 on the disc 2 enters part water process; Therefore the advantage that has in terms of existing technologies is to have changed adjustable scope after disc 2 is set; Promoted erosion resistibility in little aperture, the function of throttling step-down is more obvious, prolongs the working life of whole valve.
A kind of pressure and temperature reducing valve of the utility model please refer to Fig. 1, on the basis of technological scheme can also be in front to be positioned in the said regulating sleeve 8 at least two discs 2 are set on the said shower 1.The advantage that a plurality of discs 2 are set is further throttling step-down, promotes impact resistance, prolongs the working life of whole valve.Further optimized technical scheme is said each disc 2 average level setting.The advantage that is provided with like this is the efficient and the level that promotes impact resistance that guarantees the throttling step-down.
A kind of pressure and temperature reducing valve of the utility model please refer to Fig. 2, on the basis of technological scheme can also be in front said disc 2 through being bolted to the lower end of said outer sleeve 3, said disc 2 is positioned at said regulating sleeve 8 interior surface.The advantage of bolt is that installation is more convenient, is convenient to dismounting and replacing.Further optimized technical scheme is to be positioned at the below of said disc 2 on the said regulating sleeve 8 around at least three grooves of said regulating sleeve 8 circumference settings 9.The advantage that groove 9 is set is to have reduced the weight of integrally-regulated sleeve 8, satisfies and opens function soon.Further optimized technical scheme is that said groove 9 is keyway type groove, and the height of said groove 9 is greater than the width of said groove 9.Assurance is opened degree soon and can be regulated like this.
Above-mentionedly only several kinds of specific embodiments in the utility model are explained; But can not be as the protection domain of the utility model; Every equivalence variation of having done according to the design spirit in the utility model or modification or equal proportion are amplified or are dwindled etc., all should think the protection domain that falls into the utility model.
