In addition, in this context, it will also be understood that when an element is referred to as being "on" or "under" another element, it can be directly on "or" under "the other element or be indirectly on" or "under" the other element through intervening elements.
In one embodiment, the present application is described in further detail below with reference to specific embodiments and accompanying drawings.
As shown in fig. 1 to 5, the present embodiment provides a valve apparatus including: a valve body 1 and a valve rod 4, wherein the valve body 1 comprises a first valve port part 11 and a second valve port part 12; the valve body 1 further comprises a first connecting pipe part and a second connecting pipe part, the first connecting pipe part comprises a first circulation channel 13, the second connecting pipe part comprises a second circulation channel 14, the first circulation channel 13 and the second circulation channel 14 can be communicated through a first valve port part 11, the valve device further comprises a first cavity 131, and the valve rod 4 can approach or be far away from the first valve port part 11; the valve device further comprises a first core body 2 and a second core body 3, the first core body 2 can move axially in the first cavity 131, the first core body 2 can approach or be far away from the second valve opening portion 12, the first core body 2 is located above the second valve opening portion 12, the second core body 3 is fixedly connected or in limited connection with the second connecting pipe portion, the first core body 2 is provided with a first throttling channel 21, the second core body 3 is provided with a second throttling channel 31, and the first throttling channel 21 and the second throttling channel 31 can be communicated through the first valve opening portion 11.
Because the first core 2 can move back and forth (i.e. move up and down) under the impact of the fluid, when the first core 2 moves towards the second valve port portion 12 (i.e. the first core 2 moves down), as shown in fig. 1, the first core 2 abuts against the second valve port portion 12, so that the fluid firstly passes through the second throttling channel 31 and then flows to the lower port of the valve body 1 through the first throttling channel 21, and at this time, the two channels can simultaneously play a role of throttling, so that the amount of the fluid flowing out is small; when the first core body 2 moves in a direction away from the second valve opening portion 12 (i.e. the first core body 2 moves upward), as shown in fig. 2, the first core body 2 is separated from the second valve opening portion 12, so that the fluid firstly flows into a flow passage formed by the outer wall of the first core body 2 and the inner wall of the first pipe connecting portion, then flows into the second throttling passage 31, and finally flows out from the other port of the valve body 1, at this time, only the second throttling passage 31 plays a role of throttling, and further the moving direction of the first core body 2 is changed by changing the flow direction of the fluid. Consequently, this application can play the effect of two-way throttle through the setting of two throttle passages, and valve body 1 processing is also comparatively convenient moreover.
The connection mode of the second core body 3 and the valve body 1 comprises fixed connection and limiting connection, and the fixed connection refers to that the filter piece and the connecting pipe are installed after the filter piece and the connecting pipe are directly installed in the valve body in a press fit mode; the limit connection can keep the valve body limited by a small gap through the connecting pipe.
When the fluid flows from the outdoor air conditioner to the indoor air conditioner through the valve device, the demand for the fluid is small; when the fluid passes through the valve device from the indoor air conditioner to the outdoor air conditioner, the demand of the fluid is large, so the valve device can adjust the fluid flow by changing the movement of the first core body 2, and the fluid flow can be determined according to the specific use requirement.
As shown in fig. 4, the second throttle passage 31 includes a first throttle hole 311 and a second throttle hole 312, the second throttle hole 312 is located at an end portion of the first throttle hole 311, and the aperture of the second throttle hole 312 is larger than that of the first throttle hole 311. The first orifice 311 is a main orifice of the second throttle passage 31, and the second orifice 312 is provided to avoid the problem of refrigerant noise due to a sudden change in the diameter of the refrigerant after the refrigerant enters the second throttle passage and flows therethrough.
Specifically, the second orifice 312 is positioned at both ends of the first orifice 311, and since the fluid in the valve device flows in both directions, the second orifice 312 is positioned at both ends of the first orifice 311, and the generation of refrigerant noise can be reduced regardless of the direction in which the fluid flows. In the present embodiment, one second orifice 312 is provided as a stepped hole 312a, and the stepped hole 312a is provided such that the diameter of the second orifice 312 is gradually reduced, thereby further reducing the generation of refrigerant noise.
As shown in fig. 3, the valve body 1 further includes a second cavity 132, and the second cavity 132 and the first cavity 131 are respectively located at two sides of the second valve port portion 12, so as to facilitate the two-way flow of the fluid through the second valve port portion 12; and the first core 2 is located in the first cavity 131 and axially moves in the first cavity 131.
Wherein, the guide section that first cavity 131, second cavity 132 and second valve portion 12 formed, guide section integrated into one piece has the convenient advantage of processing, and then is convenient for valve body 1 integrated into one piece.
Specifically, the aperture of the second valve port portion 12 is smaller than the aperture of the first cavity 12, so that the first core 2 is abutted against the second valve port portion 12. When fluid flows from the second core 3 to the first core 2 (i.e. from top to bottom), the fluid in the valve body 1 pushes the first core 2 to move downward, and under the impact force of the fluid, the second valve port 12 of the first core 2 abuts, at this time, the fluid firstly enters the second throttling channel 31 of the second core 3 through the second valve port 12, and then enters the first throttling channel 21 of the first core 2, and the two channels are throttled simultaneously, so that the amount of the fluid flowing to the lower port of the valve body 1 is small.
Referring to fig. 5, further, an end surface of the first core 2 abutting against the second valve port portion 12 is provided as a tapered surface 22; after the first core 2 abuts against the second valve port portion 12, the first core 2 at least partially extends into the second valve port portion 12. Ideally, the tapered surface 22 is provided to seal the first core 2 and the second valve port 12, so that damage to the first core 2 during downward movement can be reduced, and the sealing effect between the outer wall of the first core 2 and the second valve port 12 can be improved.
Further, the first core body 2 includes a main body portion 23 and a guide portion 24, and the tapered surface 22 is located at one end of the main body portion 23; the guide portion 24 is located on the peripheral side of the body portion 23, and the guide portion 24 abuts against the inner side wall of the first pipe receiving portion, so that the guide portion 24 can play a role of guiding when the first core 2 moves up and down, thereby reducing the possibility of displacement of the first core 2. Wherein, the end surface of the guide part 24 is provided with an inclined surface 241; the inclined surface 241 is aligned with the inclined direction of the tapered surface 22, and the sealing effect between the outer wall of the first core 2 and the second valve port portion 12 can be further improved.
As shown in fig. 1, the valve rod 4 is positioned inside the valve body 1 and is in threaded connection with the valve body 1; the movement section of the first core 2 can be adjusted by screwing the valve rod 4. After screwing the valve rod 4 to make the valve rod 4 abut against the first core 2 and make the first core 2 block the first throttling channel 21, not only the first core 2 is limited from moving, but also the valve body 1 can be closed, and the valve device is closed.
Specifically, the sealing ring 41 is disposed on the periphery of the valve rod 4, so that the fluid inside the valve body 1 can be prevented from flowing out during or after the screwing process of the valve rod 4 is completed, and the valve body 1 is sealed.
Furthermore, a check ring 42 is further arranged on the peripheral side of the valve rod 4, and the check ring 42 can prevent the valve rod 4 from popping up under the pressure of fluid in the screwing process, so that a protection effect is achieved.
It should be noted that, the port of the valve body 1 where the valve rod 4 is installed is provided with a bonnet 9, and after the operation of the valve rod 4 is completed, the bonnet 9 can be screwed on the port, so as to further play a role of protection.
As shown in fig. 2, a first filter 5 is disposed at a lower port position of the valve body 1, and at least a part of the first filter 5 is located in the second cavity 132 to filter the fluid; and a second filter screen 6 is arranged at the second port of the valve body 1 and is used for filtering fluid. The external fluid is filtered by the filter screen no matter which direction the fluid enters the valve body 1 (or flows out of the valve body 1).
A sealing cap 7 is mounted at a second port of the valve body 1 provided with the second filter screen 6, so that the situation that the second filter screen 6 is flushed out of the valve body 1 by fluid can be avoided; after the sealing cap 7 is installed, the second port is provided with a connecting pipe nut 8 for connecting with an outdoor air conditioner.
In summary, the present application provides a valve device, which can reduce the processing difficulty of the valve body 1 through the optimized design of the structure of the valve device, and when the throttling needs to be performed according to the client or the system in different specifications, only the first core 2 or the second core 3 needs to be replaced, and the difficulty in various aspects such as clamping for the turning process is higher than the difficulty in directly processing the throttling hole on the valve body 1. The valve device is small in size, can realize a bidirectional throttling function, and can adjust the flow of the fluid only through the movement of the first core body 2; meanwhile, the valve body 1 can be integrally processed and formed, small holes do not need to be formed in the valve body 1, and the valve body has the advantage of convenience in processing.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
