Abstract
The utility model discloses a fluid silencer capable of filtering impurities. The fluid silencer is arranged on a valve seat and comprises an inner sleeve, wherein a plurality of first through holes are arranged on the inner sleeve, an outer sleeve is sleeved outside the inner sleeve, a plurality of second through holes are arranged on the outer sleeve, the diameter of each first through hole is equal to that of each second through hole, and the axial line of each first through hole does not coincide with that of each second through hole.
Description
Technical field
The utility model relates to a kind of fluid silencer.
Background technique
Existing fluid silencer is mounted in a sleeve on the valve seat; Sleeve is provided with many holes, can only play certain sound deadening, but for the impurity in the liquid; Can not play the effect of filtration; Impurity gets into trim inside easily, and the sealing surface of destructive valve internals causes valve shortening in working life.
Summary of the invention
But the technical problem that the utility model will solve provides a kind of fluid silencer of impurity screening.
The technological scheme that addresses the above problem is: this fluid silencer; It is installed on the valve seat and comprises inner sleeve; On inner sleeve, be provided with a plurality of first through holes; Outside inner sleeve, also be with outer sleeve, sleeve is provided with a plurality of second through holes outside, and the identical and axis of the diameter of first through hole and second through hole does not overlap mutually.
Because the diameter of first through hole and second through hole is identical and axis does not overlap mutually; First through hole, second through hole that are inside and outside sleeve stagger each other; So when valve version is opened for stream; Fluid filters through the double-deck noise reduction cage on the valve seat earlier, and it is inner to prevent that dregs from getting into trim, the sealing surface that the destructive valve internals are inner.Simultaneously because the mutual dislocation of bloop; Need change flow direction during fluid flow through orifice; Convection current interacts between the fluid, and part energy converts interior ability into, and the flow speed control when making fluid through valve seat is in minimum speed; The minimizing fluid washes away valve seat, thereby plays the effect of reduction of speed step-down noise reduction.And when valve version is closed for stream, also can play the effect of reduction of speed step-down noise reduction when fluid is flowed through bloop.
Description of drawings
Fig. 1 is stream structural representation according to the fluid silencer of the utility model when opening when valve version;
Fig. 2 is according to the structural representation of the fluid silencer of the utility model when valve version is closed for stream;
Fig. 3 is the enlarged view of the I part of Fig. 1.
Specific embodiments
Like Fig. 1, shown in 3; This fluid silencer, it is installed on the valve seat and comprises inner sleeve 1, on inner sleeve, is provided with a plurality of first through holes 11; Outside inner sleeve, also be with outer sleeve 2; Sleeve is provided with the identical and axis of the diameter of a plurality of second through hole, 21, the first through holes 11 and second through hole 21 and does not overlap mutually outside, and promptly first, second through hole staggers each other.
Because the diameter of first through hole and second through hole is identical and axis does not overlap mutually; First through hole, second through hole that are inside and outside sleeve stagger each other; So when valve version is opened for stream (as shown in Figure 1); Fluid filters through the double-deck noise reduction cage on the valve seat earlier, and it is inner to prevent that dregs from getting into trim, the sealing surface that the destructive valve internals are inner.Simultaneously because the mutual dislocation of bloop; Need change flow direction during fluid flow through orifice; Convection current interacts between the fluid, and part energy converts interior ability into, and the flow speed control when making fluid through valve seat is in minimum speed; The minimizing fluid washes away valve seat, thereby plays the effect of reduction of speed step-down noise reduction.And when valve version is closed for stream (as shown in Figure 2), also can play the effect of reduction of speed step-down noise reduction when fluid is flowed through bloop.
Preferably, as can beappreciated from fig. 3, inner sleeve 1 is connected with outer sleeve 2 Spielpassung ground.Reduction of speed step-down noise reduction and playing a role in filtering so better.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs to the protection domain of the utility model technological scheme to any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. fluid silencer; It is installed on the valve seat and comprises inner sleeve (1); On inner sleeve, be provided with a plurality of first through holes (11); It is characterized in that: outside inner sleeve, also be with outer sleeve (2), sleeve is provided with a plurality of second through holes (21) outside, and the identical and axis of the diameter of first through hole (11) and second through hole (21) does not overlap mutually.
2. fluid silencer according to claim 1 is characterized in that: inner sleeve (1) is connected with outer sleeve (2) Spielpassung ground.
