Detailed Description
Referring to fig. 1, a cross-sectional view of the integrated silencer combined with an air pressure solenoid valve is shown. The invention provides an integrally formed silencer 6 for an air pressure solenoid valve, or simply a silencer 6. The air pressure solenoid valve structure comprises a valve seat 1 and a valve body 2. The valve body 2 is connected to the valve seat 1. The valve body 2 accommodates a first core 3, a second core 5, and a coil assembly 4. The coil assembly 4 is wound around the first iron core 3 and the second iron core 5. A spring 12 is arranged in the valve seat 1, and the spring 12 is positioned at the front end of the first iron core 3. The tail end of the first core 3 faces the head end of the second core 5, and the tail end of the second core 5, that is, the exhaust end, is provided with an integrally formed muffler 6. In the present embodiment, the first core 3 is a movable member, or may be called an armature (armature); the second core 5 is a stationary member, or may be referred to as a stationary core (core).
Referring to fig. 2 to 5, a perspective view, a bottom view and a cross-sectional view of the integrally formed silencer of the present invention are shown. The integrally formed muffler 6 includes an outer cover plate 61, a center guide 63, a plurality of spoilers 67, and a peripheral wall 65, and the peripheral wall 65 is connected to a one-piece structure by extending around the outer cover plate 61. Preferably, the silencer 6 may be integrally formed by injection molding of plastic, and the material may be, for example, polyethylene terephthalate (PET), Polycarbonate (PC), or the like.
As shown in fig. 2 and 4, the outer cover plate 61 of the present embodiment is circular, but the present invention is not limited thereto, and may be polygonal, for example. The outer cover plate 61 is formed with a plurality of exhaust through holes 610, and the plurality of exhaust through holes 610 are arranged in a circular ring shape at the same intervals and are close to the outer periphery of the outer cover plate 61. More specifically, each of the vent through holes 610 has a rectangular shape and is adjacent to the peripheral wall 65. Each of the air vent holes 610 penetrates the outer and inner surfaces of the outer cover plate 61 so that air can escape from the inner surface to the outer surface of the outer cover plate 61.
A center guide post 63 is attached to the inner surface of the outer cover plate 61. The center guide post 63 of this embodiment is located at the center of the outer cover plate 61. As shown in fig. 1, after the muffler 6 is assembled with the valve body 2 of the pneumatic solenoid valve, the center guide post 63 is inserted into the passage 58 of the second core 5.
With reference to fig. 2 to 5, a plurality of spoilers 67 are disposed on the inner surface of the outer cover 61 and between the central guide post 63 and the plurality of exhaust through holes 610. The plurality of turbulent flow retaining walls 67 are arranged in a circular ring shape at the same interval. A plurality of exhaust bottlenecks 670 are formed between the plurality of turbulent flow retaining walls 67. The exhaust through holes 610 are located on the outer sides of the spoiling walls 67, as shown in fig. 3, so that the exhaust through holes 610 and the first center line L1 in the same exhaust direction correspond to a plurality of the exhaust chokes 670 and the second center line L2 in the same exhaust direction correspond to a plurality of the exhaust holes 610, and the center guide pillar 93 and the third center line L3 in the same exhaust direction are not on the same plane. In the present embodiment, the turbulent flow retaining walls 67 have six total, but are not limited thereto, and the number thereof corresponds to the number of the exhaust through holes 610, and the number of the exhaust chokes 670 also corresponds to the number of the exhaust through holes 610. Further, the width of the exhaust choke 670 is smaller than the width of the exhaust through hole 610, thereby slowing down the flow velocity of the fluid inside the muffler 6.
It should be noted that the length of each turbulent flow retaining wall 67 is smaller than the length of the peripheral wall 65. Wherein an arc surface 672 is formed on the inner side of each turbulent flow retaining wall 67, and the arc surface 672 is concave facing the central guide post 63.
The peripheral wall 65 of the present embodiment is cylindrical, extends from the periphery of the outer cover plate 61, and has a plurality of hooks 652. The present invention is not limited thereto and the peripheral wall 65 may have a polygonal cylindrical shape. The hooks 652 are located at the bottom end of the inner side surface of the peripheral wall 65, and in this embodiment, are fastened to the valve body 2, and are close to the exhaust end of the second iron core 5, so as to fix the integrally formed muffler 6. In addition, the peripheral wall 65 forms a plurality of buffer slits 650, and the plurality of buffer slits 650 are located between the plurality of hooks 652, thereby increasing the elasticity of the engagement.
In addition, referring to fig. 2 to 5, the central portion of the outer cover plate 61 of the present embodiment is recessed inward to form a tapered portion 62, the central guide post 63 is connected to the tapered portion 62, and the tapered portion 62 is located between the plurality of spoilers 67 and the central guide post 63. The center guide post 63 is tapered and gradually expands from its free end toward the tapered portion 62 of the outer cover 61. The central guide post 63 is inserted into the channel 58 of the second core 5 (as shown in fig. 1), so that the gas is uniformly distributed to the tapered portion 62, whereby the tapered portion 62 can smoothly guide the gas flow to the periphery of the outer cover 61.
As shown in fig. 4 and 5, the tapered portion 62 of the outer cover 61 forms an annular arc 622, and the annular arc 622 extends from the root of the central guide post 63 to the spoilers 67.
In summary, the integrally formed muffler provided in the embodiment of the present invention has a one-piece structure, and the installation process is simple, and the muffler 6 can be completed by engaging the exhaust end facing the second iron core 5 with the valve body 2. The tapered portion 62 of the outer cover 61 guides the gas smoothly, and reduces noise of the fluid. In addition, through the structure of the turbulent baffle 67, the exhaust through holes 610 and the first center lines in the same exhaust direction, the corresponding exhaust bottlenecks 670 and the second center lines in the same exhaust direction, and the central guide pillar and the third center lines in the same exhaust direction are not on the same plane, that is, the exhaust through holes 610 and the exhaust bottlenecks 670 may be designed to be completely or partially staggered with each other to extend the length of the flowing gas and reduce the noise of the fluid.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, so that the present invention includes all equivalent technical changes made by using the contents of the present specification and the accompanying drawings.
