Summary of the invention
Technical problem to be solved in the utility model provides a kind of inside of can bearing and lights the test of propagation of explosion not, can satisfy the explosion-proof water swivel of water-cooled circular flow requirement again.
In order to solve the problems of the technologies described above, the utility model provides a kind of explosion-proof water swivel, this explosion-proof water swivel comprises the water swivel person in charge, flange plate, the gentle lock construction of end cap unit, described water swivel is responsible for the fixedly connected flange plate of an end, the fixedly connected end cap of the other end, described flange plate and end cap are fixed on the gas lock element of construction in the water swivel person in charge, described gas lock element of construction is to be made of two hollow weir and some inserted sheets, described hollow weir simultaneously has some parallel slots, the slot of these two hollow weir constitutes some parallel gas locks gap with the two ends clamping of some inserted sheets between described inserted sheet.
Be responsible for parallel gas lock gap in order to make cooling water evenly flow through water swivel, the width of some slots of described hollow weir one side equates, spacing equates.
Further, described some inserted sheets are the stainless steel sheets that thickness equates.
Explosion-proof water swivel is inside and outside for convenience connects, and all is threaded pipe joint on described flange plate and the end cap.
As a kind of preferred version, described parallel gas lock gap is 0.3～0.8mm.
As a kind of preferred version, described parallel gas lock gap length is 35～70mm.
The beneficial effects of the utility model are:
1, technical solutions of the utility model are utilized the principle of close gap fire extinguishing, have effectively satisfied flame proof requirement and cooling water flow requirement simultaneously;
2, the technical solutions of the utility model employing has the hollow weir of slot and the scheme that inserted sheet constitutes the gas lock element of construction, and this scenario-frame is simple, be easy to guarantee machining accuracy, and processing cost is low.

Accompanying drawing figure number note: 1 inner connection tube, 2 hollow weir, 3 inserted sheets, 4 are responsible for 5 end caps, 6 flange plate, 7 slots.
Embodiment
As shown in Figure 1 and Figure 2, explosion-proof water swivel of the present utility model is to be responsible for 4, flange plate 6, inner connection tube 1, end cap 5, two hollow weir 2 and some inserted sheets 3 by one to constitute, and the described person in charge's 4 one ends are welded on flange plate 6 end faces, be responsible for 4 the other ends is welded on the end cap 5; On two hollow weir 2 one sides some parallel slots 7 are arranged, some inserted sheets 3 are inserted in corresponding parallel slot 7, two hollow weir 2 constitute the gas lock element of construction with inserted sheet 3 combination backs, this gas lock element of construction has some parallel gas locks gap, and this gas lock element of construction is fixed in the person in charge 4 by end cap 5 and flange plate 6 by two hollow weir 2; Described inner connection tube 1 end is welded in the center hole of flange plate 6; In order to connect water-cooling tube, described inner connection tube 1 and end cap 5 are provided with screw thread.
As Fig. 3, Fig. 4 and shown in Figure 5, hollow weir 2 of the present utility model is a cuboid, and this cuboid simultaneously is provided with the slot 7 of some parallel distributions, and the width of these some slots 7 equates and spacing equates.
As Fig. 6, shown in Figure 7, inserted sheet 3 of the present utility model is stainless steel rectangular body sheets that thickness equates.
According to the principle of gap fire extinguishing, the width in the utility model gas lock gap is 0.3～0.8mm, preferentially selects 0.5mm, and the length in this gas lock gap is 35～70mm, preferentially selects 50mm.
This explosion-proof water swivel can be applied in the explosion-proof frequency converter water-cooled cycle cooling system, is used to connect inner water-cooling tube of explosion-proof casing and external refrigeration water pipe.The one side of the flange plate 6 of this explosion-proof water swivel is an explosion suppresion surface, and the outer flange plate of this explosion suppresion surface and explosion-resistant enclosure housing is with six bolton.Cooling water enters the inside water-cooling tube of explosion-proof casing through end cap 5, inserted sheet 3 formed gas lock gaps, flange plate 6 and inner connection tube 1.On the one hand, the long-pending sum of this gas lock clearance cross section is more than or equal to the water-cooling tube cross-section area, and promptly the needs of circulating cooling water flow can, can be satisfied by flow more than or equal to the water-cooling tube flow in the gas lock gap therefore; On the other hand, this gas lock gap length and width can enough be shunted and extinguish internal point and fire fried kindling material, thereby do not ignite explosion-proof casing extraneous explosion gas, have reliable explosion insulation performance.
Technical solutions of the utility model are not limited to the described scope of above-mentioned specific embodiment, and every technology distortion of being done according to the utility model know-why all falls within the protection domain of the present utility model.
