Abstract
The invention provides a self-locking type water connector for a direct flow converter valve. The water connector specifically comprises a main body, a water nozzle, a step pipe and a nut which are sequentially arranged. The water connector is characterized in that a groove used for placing a sealing ring is arranged at one end of the step pipe, and the nut is connected with the water nozzle and is sleeved on the outside of the step pipe. The water connector can achieve the aims of being high in water pressure resistance, capable of bearing 2MPa working water pressure in long term, large in through diameter, small in flow resistance, high in self-sealing performance, good in corrosion resistance and anti-shock performance, convenient to install, capable of ensuring long-time high-reliability work and capable of being separated when the connector is used to facilitate replacement and maintenance of the equipment.
Description
Technical field
The invention belongs to field of power electronics, be specifically related to a kind of DC converter valve self-locking water joint.
Background technique
Constituent is widely used in the direct-current transmission converter valve cooling current, and the pipe joint performance quality of constituent directly has influence on sealing and the unfailing performance of water circuit system.Therefore in practical implementation, owing to leakage and obstruction accident that the reasons such as the water swivel design and use are unreasonable cause are of common occurrence, to the appropriate design of water swivel with select converter valve moved reliably and with long-term and seem extremely important.
The mode of the water pipe connection device of current employing mainly contains two kinds, and a kind of is to adopt the tapered thread sealing; Another is the Placement of rapid pipe joint.The tapered thread sealed characteristic accurately meshes by tapered thread and reaches sealing effect, needs to adopt sealant tape to improve sealability.Liquid directly contact with thread thereby can bring pollution and etching problem in the water pipe, cause not quick detachable with can not Reusability, the life-span reduction.Because the screw-thread fit precision is high, has increased difficulty of processing.Under the vibrations condition, leak thereby directly cause the thread seal inefficacy to produce behind the nut loosening.The Placement of rapid pipe joint is generally used simply in daily life because of its installing/dismounting, and its characteristics adopt multiple-sealed, and the many reliabilities of component reduce, be applicable to the larger pipe-line system of flow, but latus rectum is little mostly, and circulating resistance is large, and adopts metallic material.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of DC converter valve self-locking water joint, simple and reasonable, operation is cheap easily.
In order to realize the foregoing invention purpose, the present invention takes following technological scheme:
A kind of DC converter valve self-locking water joint comprises: the main body that sets gradually, water nozzle, step pipe and nut; It is characterized in that: described step Guan Yiduan is provided with the groove of placing seal ring, and described nut connects described water nozzle, is placed in the described step pipe outside.
Preferably, described groove is located on the described step end surfaces, and described seal ring is located in the described groove; Described step pipe top is pressed on the bottom surface end face of described water nozzle, forms end face seal with precompressed described seal ring.
Preferably, described water nozzle inwall is provided with screw thread; Described nut is locking nut; Described locking nut is twisted by described screw thread and described water nozzle and is connect, and the top is pressed on the outer of described step pipe.
Preferably, described main body is provided with locating stud; Described locking nut is provided with snap ring; Described snap ring is positioned at the described locking nut outside by described locating stud.
Preferably, described seal ring is the O RunddichtringO.
Preferably, described snap ring is the Hexagon snap ring.
Preferably, described locking nut and described water nozzle adopt material of the same race.
Preferably, described material of the same race is metalwork or working of plastics.
Preferably, described working of plastics is PVDF.
Compared with prior art, beneficial effect of the present invention is:
1) good sealability.What the O RunddichtringO adopted is end face seal, has avoided the high request of thread seal double thread machining accuracy.
2) good switching performance.Water nozzle on water pipe and the apparatus body directly is threaded connection locking, can quick-detachment, and easy for installation.
3) economic performance: compare with the water swivel of routine, but economical with materials expense 30%.Because its is simple in structure, installation, replacing make things convenient for simple and direct, can improve 2～3 times of construction efficiency.
4) the water pressure resistance ability is strong: can bear for a long time the 2MPa work water pressure.
5) latus rectum is large, and flow resistance is little.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
Novel DC converter valve self-locking water joint of the present invention, it comprises water nozzle, locating stud, step pipe, seal ring, nut and snap ring.Shown in Fig. 1-2, in the water nozzle with step pipe (such as Fig. 3) the interventional instrument body of seal ring, under the effect of nut pretightening force, the seal ring top is pressed on the end face of water nozzle bottom surface precompressed seal ring and end face generation seal action; Nut is connected with the water nozzle internal thread locking, and the top is pressed on the outer step of step pipe; Step pipe and water nozzle bottom surface with seal ring form end face seal under seal ring precompression condition, avoid water to go out from the pipe inner wall surface current.When the inboard hydraulic pressure of step pipe Baltimore groove during in the seal ring inner chamber, the interior pressure that produces will be dispersed throughout the whole internal surface of seal ring, and seal ring is pressed to the Baltimore groove outside form crush seal, the interior pressure that acts on simultaneously the seal ring edge can produce larger pressure to sealing surface.Interior pressure is higher, and the pressure of seal ring is also larger, and sealing effect is just more obvious, thereby prevents the leakage of fluid.
At nut after moment tightens in accordance with regulations, by the breach on the snap ring (such as Fig. 4) snap ring is placed on the nut, position by locating stud on the body, prevent nut because of equipment vibrations or expand with heat and contract with cold and cause loosening, the liquid of having avoided the seal ring coupling mechanism force to cause is not revealed.Cause the leakage possibility in order further to reduce to expand with heat and contract with cold, nut and water nozzle adopt the same material, as are all metalwork or working of plastics, and typical working of plastics is PVDF.
Should be noted that at last: above embodiment is only in order to illustrate that technological scheme of the present invention is not intended to limit, although with reference to above-described embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement the specific embodiment of the present invention, and do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present invention.
