Detailed Description
Referring to fig. 1, the drinking device for prisons comprises a water supply source 100 independently installed in a non-jail room, wherein the water supply source 100 comprises a water purifying device, a heating device, a heat exchanging device and an incubator (each device of the water supply source is a conventional device, and thus is not shown in the drawing). The external water source of purifier and purify this water source and carry heating device with it and heat, heat exchange device carries the heat-preserving box in with the water of heating device heating after cooling down, and the heat-preserving box is carried its heat retaining water to the play water installation 101 of each jail room through the pipeline (jail room of prison is provided with the play water installation 101 with water supply 100 intercommunication).
The water outlet device 101 comprises a water receiving box 1, a valve body assembly and a switch device.
As shown in fig. 2 and 3, the water receiving box 1 includes a box body 11 having an opening and a panel 12 formed to cover the opening. The water receiving box 1 is installed and fixed on the wall of the firm room, the water receiving box 1 is provided with a panel 12, and a first through hole 13 is formed on the panel 12.
As shown in fig. 4 to 7, a valve body assembly is formed with a support table 24 (specifically, mounted on the valve seat 2) having a shape of a revolution solid near a first end thereof, the valve body assembly is provided with a water inlet 22 and a water outlet 23 near a second end thereof, the valve body assembly is fixed in an axial direction by passing the second end thereof through the first through hole 13 and supporting the support table 24 against one side of the panel 12 by the fastening member 8, the water inlet 22 and the water outlet 23 are located at the other side of the panel 12, and the water inlet 22 is communicated with the water supply source 100;
Specifically, the valve body assembly includes a valve seat 2 and a valve spool 3.
The valve seat 2 has a valve seat inner cavity 21, the valve core 3 is fixedly installed in the valve seat inner cavity 21 (more specifically, the valve core 3 is installed in the valve seat inner cavity 21 through a thread structure) and a first end of the valve core 3 extends out of the valve seat 2, the isolating protrusion 31 is convexly arranged on the outer peripheral wall of the valve core 3, the isolating protrusion 31 divides the valve seat inner cavity 21 into a first inner cavity 211 and a second inner cavity 212 which are isolated from each other, and in order to better isolate the first inner cavity 211 from the second inner cavity 212, the outer peripheral wall of the isolating protrusion 31 is sleeved with a sealing ring. The water inlet 22 is provided on the peripheral wall of the first inner chamber 211, and the water outlet 23 is provided on the end wall of the second inner chamber 212.
The valve core 3 is provided with a channel 32 running through two end faces of the valve core 3 along the axial direction, the side wall of the valve core 3 corresponding to the position of the first inner cavity 211 is provided with a side hole 33 communicated with the channel 32, and the inner diameter of a section of the channel 32 corresponding to the water inlet 22 to the water outlet 23 is larger than the outer diameter of the valve core 3, so that a gap 34 for liquid to flow through is formed between the section of the channel 32 and the valve core 3.
The switch device comprises a valve rod 4 and a button 5 which is arranged on the first end of the valve body assembly (specifically, arranged on the valve seat 2) and is in a rotary body shape, the rotary shaft of the button 5 is coaxial with the rotary shaft of the abutting table 24, under the normal state, the switch device blocks the communication between the water inlet 22 and the water outlet 23 (as shown in figure 6), and the button 5 is pressed, so that the switch device allows the communication between the water inlet 22 and the water outlet 23 (as shown in figure 7); the water outlet 23 extends into the water receiving box 1 through a pipeline.
The first end of the valve rod 4 is provided with a plug 41 for preventing the passage 32 from communicating with the second inner cavity 212, more specifically, a mounting table 42 is formed on the side surface of the first end of the valve rod 4, and the plug 41 is a sealing ring which is sleeved on the valve rod 4 and abuts against the table surface of the mounting table 42. The second end of the valve rod 4 is threaded with the key 5 through the passage 32.
