Abstract

The utility model belongs to the technical field of uranium conversion and particular relates to a novel condensing hydraulic valve for uranium conversion. According to the novel condensing hydraulic valve for uranium conversion, in the closing state of the valve, leakage occurs at the packing position, a material is sealed by fastening a packing gland, controllability of the valve is improved, meanwhile a valve protective cover is removed, a valve structure is improved, and fast overhaul is facilitated. The novel condensing hydraulic valve comprises a valve rod (1), a large gland (2), the packing gland (3), packing (4), a valve seat (5), a valve head (6) and a hanging basket (7), wherein a cylindrical hollow cavity is formed in the large gland and the valve seat, the large gland (2) is arranged at the upper end of the valve seat (5), the valve rod penetrates through the large gland (2) and the valve seat (5), the packing gland (3) is arranged between the valve rod (1) and the large gland (2), the packing (4) is arranged between the valve rod (1) at the lower end of the packing gland (3) and the valve seat (5) and clamped on a clamping groove in the valve seat (5), and the valve head (6) is arranged at the lower end of the valve rod (1).

Description

Uranium transforms novel condensation liquefaction valve
Technical field
The invention belongs to uranium transformation technology field, be specifically related to a kind of uranium and transform novel condensation liquefaction valve.
Background technique
DN20 liquefaction valve is that uranium transforms production line UF6 liquid phase sampling pipe control valve, and in view of reliability, the security requirement of dose protection and control operation, this valve, in material conveying process, must guarantee that its zero leakage, zero dimension protect.Therefore in the time of this valve of design, need consider the technical features such as its operating characteristic, structural characteristics, valve material corrosion resistance, sealability.In actual production run process, every controlling elements such as this valve operation Security, maintenance convenience, radiation shielding are through producing checking, there is many defects, especially under valve closing state, when filler position occurs to leak, valve rod must be screwed out, can pass through the fastening filler of Gland.After this operating process exists locking nut loosening, valve rod is deviate from, and causes the danger of material from leakage, and operator are with material operation simultaneously, are unfavorable for dose protection, therefore need be according to the requirement of technique safety in utilization, redesign liquefaction sampling control valve.
Summary of the invention
Object of the present invention; for prior art deficiency; provide one realize valve in off position under; leak at filler position; by fastening Gland sealants, improve the controllability of valve, remove valve protecting jacket simultaneously; improve valve mechanism, the uranium of being convenient to Quick overhaul transforms novel condensation liquefaction valve.
Technological scheme of the present invention is:
A kind of uranium transforms novel condensation liquefaction valve, comprises valve rod, large gland, Gland, filler, valve seat, valve head and hanging basket; Wherein said large gland and valve seat inside are cylindrical, hollow cavity, large gland is located at valve seat upper end, valve rod runs through large gland and valve seat, Gland is located between valve rod and large gland, filler is located between Gland lower end valve rod and valve seat, be stuck on the draw-in groove on valve seat, valve head is located at valve rod lower end.
Material that described valve rod uses is 45 steel, and serviceability temperature is 200 ℃.
Described Gland material is Q235A, 200 ℃ of serviceability temperatures.
Described hanging basket material adopts Q235A, entirety processing, and in hanging basket, thread die cutting adopts copper inner sleeve screw thread, is embedded in hanging basket upper flange inside.
The invention has the beneficial effects as follows:
1. Gland, by bolton, improves operating security;
2. under valve opening state, once leak, because the upper and lower displacement of valve rod does not affect the fastening of Gland, therefore can first screw valve rod, utilize valve head sealing gasket to carry out valve passage sealing, stop material to leak at passage place, fastening gland stud, realizes the pressure sealing to filler.Valve in off position under, sealing failure of fillers or change when filler, screws valve stem seal passage, carries out fastening or dismounting by gland clamping bolt, material from leakage is effectively controlled;
3. when Gland occurs that mechanical deterioration need to be changed, fastening valve rod, sealing channel, directly spare unit are changed rear fastening, can realize do not stop pipeline medium carry, complete maintenance at station, improve overhaul efficiency.
Accompanying drawing explanation
Fig. 1 is that uranium transforms novel condensation liquefaction valve schematic diagram;
Fig. 2 is that uranium transforms novel condensation liquefaction valve side view;
In figure, 1. valve rod, 2. large gland, 3. Gland, 4. filler, 5. valve seat, 6. valve head, 7. hanging basket.
Embodiment
A kind of uranium the present invention being proposed below in conjunction with accompanying drawing and embodiment transforms novel condensation liquefaction valve and further introduces:
A kind of uranium transforms novel condensation liquefaction valve, comprises valve rod 1, large gland 2, Gland 3, filler 4, valve seat 5, valve head 6 and hanging basket 7; Wherein said large gland 2 and valve seat 5 inside are cylindrical, hollow cavity, large gland 2 is located at valve seat 5 upper ends, valve rod 1 runs through large gland 2 and valve seat 5, Gland 3 is located between valve rod 1 and large gland 2, filler 4 is located between Gland 3 lower end valve rods 1 and valve seat 5, be stuck on the draw-in groove on valve seat 5, valve head 6 is located at valve rod 1 lower end.
Described valve rod 1 material that uses is 45 steel, and serviceability temperature is 200 ℃.
Described Gland material is Q235A, 200 ℃ of serviceability temperatures.
Described hanging basket 7 materials adopt Q235A, entirety processing, and in hanging basket, thread die cutting adopts copper inner sleeve screw thread, is embedded in hanging basket upper flange inside.
Gland and valve body carry out split design, on the principle basis of Gland and valve body Split type structure, valve body and hanging basket are bolted, and in hanging basket, thread die cutting and valve rod are threaded connection, and realize the lifting of valve rod.Its form of gland is kidney-shaped flange, is connected with hanging basket by bolt.It is relatively independent that this structure has realized valve rod lifting, gland compresses filler operation.When valve opening or while closing, if the packing seal of valve rod place damages, the stuffing box packing of valve rod place is further pressurizeed, only need screw fastening stud, can screw valve rod simultaneously, prevention material further leaks.
