A pressure relief device 100 according to an embodiment of the invention is described below with reference to fig. 1-6.
As shown in fig. 1 to 6, a pressure relief device 100 according to an embodiment of the present invention includes: a housing 10 and a moveable member 20.
The shell 10 is provided with a water outlet channel 12 and a plurality of water inlet channels 13, a communication port 11 is arranged between the water outlet channel 12 and at least one water inlet channel 13, the movable piece 20 is arranged in the water outlet channel 12, and the movable piece 20 can be switched between an initial state and a pressure relief state.
When the moving member 20 is in the initial state, the moving member 20 may block the communication port 11, so that the water inlet channel 13 and the water outlet channel 12 are not communicated, that is, the water inlet channel 13 and the water outlet channel 12 may be separately passed through, water from a water source may flow into a device using the pressure relief device 100 through the water inlet channel 13, and water in the device may be discharged to the outside through the water outlet channel 12; when the moving member 20 is in the pressure relief state, the moving member 20 opens the communication port 11, so that the water inlet channel 13 and the water outlet channel 12 can be communicated, that is, when the water pressure in the water inlet channel 13 is too high, the high-pressure water can flow in the low-pressure direction through the communication between the water inlet channel 13 and the water outlet channel 12, and the pressure relief is completed when the pressure in the water inlet channel 13 is equal to the pressure in the water outlet channel 12.
According to the pressure relief device 100 provided by the embodiment of the invention, the plurality of water inlet channels 13 and the plurality of water outlet channels 12 are integrated in the shell 10, so that the pressure relief device 100 can realize the shunting function of a waterway, and more benefits are provided for users; the pressure in each channel can be integrated together to realize overload pressure relief by arranging the communication port 13, so that the use number of the traditional pressure relief device is reduced, and the space utilization rate is improved; and the structure is simple and compact, the pressure relief device 100 is convenient to install in any equipment, the universality is improved, and the user experience is good.
According to an embodiment of the present invention, when the pressure in the water inlet channel 13 is greater than the predetermined pressure, the movable member 20 opens the communication port 11, so that the water inlet channel 13 is communicated with the water outlet channel 12, the water outlet channel 12 is communicated with the outside, and therefore, the water inlet channel 13 is always in a normal pressure state, the pressure in the water inlet channel 13 is greater than the normal pressure, and the high-pressure water in the water inlet channel 13 flows towards the water outlet channel 12 by using the relatively low pressure of the water outlet channel 12, thereby achieving pressure relief.

Further, when the pressure in the water inlet channel 13 is greater than the elastic force of the elastic member 22, the pressure pushes the blocking portion 21 to overcome the elastic force of the elastic member 22, and the blocking portion 21 moves under the action of the pressure in the water inlet channel 13, so that the communication port 11 can be opened, and the water inlet channel 13 is communicated with the water outlet channel 12.
Because the water outlet channel 12 is directly connected with the outside atmosphere, the pressure is far less than the pressure in the water inlet channel 13, when the water inlet channel 13 is communicated with the water outlet channel 12, high-pressure water flows towards the direction of low pressure, and when the pressures in the water inlet channel 13 and the water outlet channel 12 are equal, the pressure relief work is completed; at this time, the blocking portion 21 is pressed at the communication port 11 again by the elastic force of the elastic member 22, and the movable member 20 is restored to the initial state; when the pressure in the water inlet channel 13 is raised again, the pressure can be released repeatedly.
As shown in fig. 6, in some examples, a limiting cavity 18 is provided in the outlet passage 12, and the limiting cavity 18 is disposed around the communication port 11 to facilitate connection between the inlet passage 13 and the outlet passage 12 through the limiting cavity 18. The blocking part 21 is suitable for moving in the limiting cavity 18, so that the situation that the blocking part 21 deviates from the communication port 11 when the initial state and the pressure relief state are switched, the communication port 11 cannot be blocked, and the pressure relief device 100 fails is avoided.
Specifically, a limiting convex ring is arranged in the water outlet channel 12, and the limiting convex ring surrounds the communication port 11 so as to enable the water inlet channel 13 to be connected with the water outlet channel 12 through the limiting convex ring, and meanwhile, a limiting cavity 18 surrounding the communication port 11 is formed at the communication port.
In a further example, the blocking portion 21 is formed into a column shape, the limiting cavity 18 is also formed into a column shape, the axial length of the limiting cavity 18 is greater than that of the blocking portion 21, it is further ensured that the blocking portion 21 is always located in the limiting cavity 18 when moving, and does not deviate from the communication port 11, and the situation that the communication port 11 cannot be blocked to cause shunt failure of the pressure relief device 100 is avoided.
According to an embodiment of the present invention, a partition plate 19 is disposed in the housing 10, the communication port 11 is disposed on the partition plate 19, and the partition plate 19 can separate the water inlet channel 13 from the water outlet channel 12, so that the water inlet channel 13 and the water outlet channel 12 are not communicated with each other, thereby achieving the flow diversion of the pressure relief device 100.
As shown in fig. 5, in some examples, a sealing member 40 is disposed at an end of the movable member 20 facing the partition 19, when the movable member 20 moves, the sealing member 40 moves synchronously with the movable member 20, when the movable member 20 is in an initial state, the movable member 20 blocks the communication port 11, and at this time, the sealing member 40 is in abutting connection with the partition 19, so that the sealing property at the communication port 11 is ensured, and the water outlet channel 12 is prevented from being communicated with the water inlet channel 13 in this state, thereby preventing the flow dividing effect of the pressure relief device 100 from being affected.
