Description of the drawings
Fig. 1 is the internal structure schematic diagram of mute throttling stop valve preferred embodiment described in the utility model.
Fig. 2 is noise reduction grid retainer plate schematic diagram described in the utility model.
Specific implementation mode
The preferred embodiment of the utility model is described in detail below.
A kind of mute cut-off throttle valve preferred embodiment disclosed in the utility model, sectional structure as shown in Figure 1,
Setting includes a valve body 110, and a throttle orifice 111 is provided on the valve body 110, specifically, can be provided in valve body
On a 110 throttling bearing；It is provided on an at least wing passage for the throttle orifice 111 and to be expanded outwardly from throttle orifice 111
Horn mouth 112 is used for noise reduction.When the principle of noise reduction is to pass through from the throttle orifice 111 when fluorine stream, the end of throttle orifice 111
Noise can be formed within side horn mouth 112, which can propagate to the side wall of horn mouth 112, and noise is imported after side wall reflects
Sound source, since the phase after reflection can form the difference with original noise phase, to form de-noising（With the original that amplifies of loudspeaker
Reason is on the contrary, noise is formed in horn mouth, and through side wall reflection polymerization, the noise between out of phase can cancel out each other, to real
Existing de-noising is mute）.
In mute cut-off throttle valve described in the utility model, all it is arranged respectively on two wing passages of the throttle orifice 111
There is the horn mouth 112 expanded outwardly from throttle orifice, two horn mouths are thus adapted to fluorine in throttle valve work backwards to being arranged
Stream needs the characteristics of two-way flow, no matter being flowed to which direction, can obtain the loudspeaker after stream passes upward through throttle orifice
Mouth noise reduction process, to realize mute cut-off throttle valve product.
The inner wall of horn mouth 112 described in the utility model is set as the expansion pattern of straight line inner wall, so as to better
Realize the reflection to noise.Meanwhile being provided with noise reduction grid retainer plate on the opening maximum gauge position of the horn mouth 112
113, as shown in Fig. 2, for being combed to the sinuous flow in fluorine stream, further muting function may be implemented.
Mute cut-off throttle valve described in the utility model is provided with throttling bearing 114 in conventional shut-off valve bottom, described
Throttling bearing 114 is a component part of valve body 110, can the setting of integrated or connected other parts.The throttling bearing 114
The inlet of throttle orifice is provided with inlet chamber 115, the fluorine stream flowing to ensure two-way all has mute de-noising effect, is saving
The both sides of discharge orifice are all respectively arranged with inlet chamber 115, and inlet chamber 115 is that the most width position of horn mouth 112 extends outwardly one
Fixed width is formed；The bottom side of inlet chamber 115 is provided with 113 component of noise reduction grid retainer plate.Noise reduction grid assembly is the bottom of at
Portion is provided with circular ring shape retainer plate, and the outer diameter of the retainer plate is slightly less than the internal diameter of inlet chamber 115.In the round retainer plate
Noise reduction grid group is provided on 113, the noise reduction grid group is cylindrical type, and inside is covered with grid.
114 middle part of the throttling bearing is provided with throttle orifice 111, internal diameter and the length foundation of the throttle orifice 111
It flow careful design required for cooling condition and is process, ensures that the refrigerant passed through reaches the flow of specified refrigeration.Institute
The benefit for stating setting throttle orifice 111 on throttling bearing 114 is that throttle orifice is arranged on spool compared with the existing technology, processing technology
More simple, without welding in water, and product quality is easier to ensure that.
Horn mouth is respectively arranged at the entrance and exit of the throttle orifice 111, two horn mouths are oppositely arranged backwards.
The angle of the horn mouth 112 is set as A values, and angular range is at 30 ° -45 °.By noise reduction grid at both ends horn mouth 112
After component is staggered relatively, limit grid is extruded using indentation apart from the nearlyr side of horn mouth in noise reduction grid retainer plate and limited
Ring.The spacing ring prevents skidding off for noise reduction grid assembly after being used to assemble.In this way when assembling shutoff valve described in the utility model
Welding in water is avoided, can be processed and formed at one time, ensure that the yield of product.
When refrigerant from condensator outlet after the throttle orifice 111 of throttle plate aperture, reach the horn mouth 112 of outlet, this
When the gaseous refrigerant that is flashed so that the sound wave along pipe transmmision is reflected back to Sounnd source direction using pipeline section mutation, to
Sound energy reflection is set to go back to original place.
Furthermore with the reflection at the several interfaces of horn mouth side wall, original first sound wave propagated forward is made to be returned to original
Point, and turn back propagate forward again, which converges with second sound wave propagated forward not yet reflected, and the two is being shaken
Equal on width, the odd-multiple of poor 180 degree, offsets to interfere with each other in phase.
In addition, the sectional area because of refrigerant increases, air pressure expansion is slowed down, and reduces the noise of air-flow rapid flow generation, together
When high pressure gas when passing through the reticular structure stainless steel wire of the noise reduction grid retainer plate 113, gas is obstructed, and flow direction changes
Become, has been greatly reduced gas flow rate, noise is made to further decrease.When refrigerant is rolled into a ball by grid, each grid divides source of students
It is reflected for multi-acoustical and to all directions, second sound wave propagated forward which is reflected with other converges, and two
Person is equal on amplitude, and the odd-multiple of poor 180 degree, offsets to interfere with each other in phase.
Noise reduction grid assembly described in the utility model may also act as filter screen, can prevent system contaminants, ensure that and is
The reliability service of system, while saving cost.Use such throttling stop valve, it is only necessary to will take over one end and condensator outlet end
Welding saves solder joint, is effectively improved production efficiency.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
