Detailed Description

As shown in fig. 2, the fuel rod application device operated under reduced pressure is formed by integrally connecting a water reaction container a with a feeding mechanism at the top, a group of pressure conduction containers B and a Y-shaped return conduit C respectively located at both sides of the water reaction container a, as can be seen by comparing with fig. 1 and 9: 1, there are four tubular ports, which are symmetrically distributed on both sides of the water reaction vessel a with the top dosing mechanism, and are integrally connected with the pressure conduction vessel B, that is, there are two input and output end pipes A2a with stop valves respectively located on the bottom of the water reaction vessel a and two pressure transmission conduits A2B respectively located above the water reaction vessel a, and these four end pipes are fixedly connected with the pressure conduction vessel B by directly inserting them into the corresponding ports of the pressure conduction vessel B, that is, the corresponding ports B2a and B2B provided on the pressure conduction vessel B have inner diameters respectively larger than or equal to the outer diameters of the input and output end pipes A2a and the pressure transmission conduits A2B on the top dosing mechanism equipped vessel a. 2, the top cover B1a of the pressure conduction container B is conical, which will help to achieve the maximum pressurization effect during the pressure conduction process. 3, the pressure conduction container B is provided with two corresponding bag-holding ports B2a and B2B at one side of the integrated connection with the water reaction container A with the feeding mechanism at the top, and a one-way valve B2B1 is provided at the inner side of the bag-holding port B2B, so that the effective decompression feeding effect is finally formed by the action of the one-way valve B2B1, when the stop valve on the bottom end pipe A2a of the container A with the feeding mechanism at the top is closed, the direction of pressure conduction is limited by the one-way valve B2B1, so that the inner part of the water reaction container A with the feeding mechanism at the top is in a semi-closed state, so-called siphon can be formed and used as the working pressure required for feeding only by decompressing the container, in other words, if the containers are communicated with each other, the siphon effect or the useful pressure related to feeding the fuel rod can not be generated by pressurizing or decompressing the container, the technical purpose to be implemented by the present application is to solve the problem of putting fuel rods by means of siphon action, and how to implement the technical purpose is further detailed in the following drawings;

as shown in fig. 3, the water reaction vessel a with the top equipped with the feeding mechanism is formed by integrally connecting a top cover type pressure-reducing feeder a1, a high pressure resistant vessel a2 with a double-layer connecting port, and an inner convergent bottom cover A3c with a base and a disc-shaped discharging end through a connecting bolt a4, and the inner convergent bottom cover A3c with a base and a disc-shaped discharging end is formed by an inner convergent bottom cover A3a, a discharging one-way valve A3B with a disc-shaped end, and a base A3c with a wire inlet and outlet opening (the discharging one-way valve A3B with a disc-shaped end is the "one-way valve B3 with a disc-shaped end" in application No. 201810626432.1) as shown in fig. 4.

The top cover type pressure reducing dispenser A1 shown in fig. 6 is composed of a push type dispensing mechanism A1a operated by an electromagnetic valve, a high pressure resistant container top cover A1b, a pressure reducing conduit A1c, a discharge sleeve A1d insulated from the outside and an isolation chassis A1e, wherein the high pressure resistant container top cover A1b is provided with a hole A1b1 for positioning and connecting a pipeline, and the top of the pressure reducing conduit A1c is provided with a pressure sensor A1c1 and an electromagnetic valve A1c2 operated by artificial intelligence;

as shown in fig. 7, the push-type launching mechanism A1a operated by an electromagnetic valve is composed of a bulb tube valve A1A1 operated by an electromagnetic valve, a push sleeve A1a2 provided with a fuel tank, and a gear and rack reciprocating linkage mechanism A1a3,

the gear and rack reciprocating linkage mechanism A1a3 is composed of a rack A1a3a, a groove type clamping frame A1a3b with a wheel shaft, an incomplete gear A1a3c, a horizontal backing plate A1a3d, a fixed pulley A1a3e, a low-rotation-speed micro motor axially connected with the gear and a plunger type spring (neither of which is shown in the figure) connected with the tail line of the rack in sequence; as can be seen from the figure: in the structure, the rack A1a3a is always subjected to two forces with completely opposite directions, one is a pushing force formed by a low-speed micro motor acting on the incomplete gear and then acting on the front end of the rack, and the other is a back pulling force formed by a tail line at the back end of the rack, namely the two interactive wheel alternate actions generated by the two forces enable the rack to continuously repeat reciprocating operation in a semi-automatic mode; the interaction principle and the more specific structural relationship between the parts of the mechanism can be more easily understood only by combining the corresponding sectional schematic diagrams, and the further description of these problems is given in figures 10 and 11 by the sectional schematic diagrams,

as shown in fig. 10, when the rack A1a3a is operated toward the front end thereof by the incomplete gear A1a3C, the fuel rod or granular fuel thrown into the pushing sleeve A1a2 is firstly fed into the ball valve cavity in the transverse direction, and at the same time the incomplete gear A1a3C is just rotated to the bald tooth portion thereof, so that the rack A1a3a is returned to the starting position thereof by the pulling of the plunger spring, and thereafter the ball type valve A1A1 is rotated by 90 degrees to convert the ball valve cavity thereof into the longitudinal direction and place the fuel rod therein under the injection pressure of the Y-type return conduit C, and in the process, the ball valve is thrown in the direction and the injection pressure is opened and closed, and the injection pressure is continuously applied to the tail portion of the fuel rod, as described above, the injection pressure is not continuously increased from the fuel rod due to the fact that the container is simultaneously subjected to the internal a pressure thereof The kinetic energy required for the operation, especially if the containers are interconnected, neither external nor internal depressurization thereof, will generate a truly useful operating pressure in connection with the fuel rod feeding, it is only possible to generate an effective siphon effect contributing to the stable descending of the fuel rods by means of internal depressurization of the water reaction container a when the interior of the water reaction container a is in a semi-closed state, i.e. by closing the shut-off valve A2a of the bottom end tube thereof and under the synergistic effect of the non-return valve B2B in the pressure-conducting container B, and the same effect and effect can be generated regardless of the internal pressure, which is particularly important for the intermittent fuel rod operation to be performed next by the discharge, which of course must be possible under the control of artificial intelligence.

The specific structure of the discharge sleeve A1d insulated from the outside is shown in fig. 8, and is composed of a metal tube A1d1, two ceramic sleeves A1d2 coated at the upper and lower ends, and a clasping type conductive terminal A1d3, wherein the clasping type conductive terminal A1d3 is connected with a wire, and the other end of the wire is fixed at the outer side of the top cover through a positioning connection hole A1b1 on the top cover and finally connected with the wire on the electric welding machine; the top end of the discharge sleeve A1d insulated from the outside is sleeved and fixed inside A1b, and the bottom end of the discharge sleeve A1d can extend to the position below the water level inside the container;

the applicant believes that: according to the technical scheme provided by the application, the continuous feeding and operation of the discharge fuel rod are possible, and a firmer foundation is laid for the further combination of the plasma arc and the water reaction technology.
