Abstract
The utility model relates to a rotary joint for a high pressure water pipe. The utility model not only can satisfy the requirements of changing the flow direction of low viscosity flow and connecting when two rectangular connecting pieces have relative rotation or relative swinging motion but also solve the problems of normal work under high pressure environment. The utility model has the solved technical scheme that a welding pipe joint nozzle is fixedly arranged on a casing of the rotary joint; threads are arranged on the outer diameter of the welding pipe joint nozzle; a spindle is inserted in the casing of the rotary joint; a sealing O-ring retaining ring and O-rings which are overlapped together are arranged between the inner surfaces of the spindle and the rotary joint; a positioning control hole is arranged on the spindle. The utility model has the characteristics of convenient installation and use, little space occupation, long service life, labor-saving operation, no leakage, etc.; not only is the direction of the flow in a pipe changed, but also the connecting requirements when rectangular connecting pieces have the relative rotation can be satisfied; an extinguishing device reduces readiness time and can be freely moved with the size of the area of a fire source to gain precious time for fire extinguishing when the fire extinguishing needs to be carried out.
Description
One, technical field
The utility model relates to the connection part between a kind of flexible pipe and metal tube or the flexible pipe, and particularly a kind of low viscosity fluid that can be used for flows to the pipeline high-pressure water pipe swivel joint that meets at right angles shape.
Two, background technique
In portable high pressure single fluid fine spray extinguisher, the high-pressure water flow that forms through plunger pump is sent into spray gun by the high-pressure rubber pipe capstan winch and is formed heavy pressure fine spray by shower nozzle and put out a fire.In order to satisfy the needs of remote fire extinguishing, length is generally tens meters or the flame-retardant rubber pipe of going up km and is entangled on the hose reel, at capstan winch running shaft place, need join by the flexible pipe that pipe joint and plunger pump come out.Common pipe joint is short working life, and sealing effect is poor, can not satisfy the high-pressure water pipe that changes when between two of direction of flow and the rectangular connections relative rotation or swing being arranged and connect needs.
Three, model utility content
Can not satisfy the problem that changes the connection needs when between two of direction of flow and the rectangular connections relative rotation or swing being arranged for overcoming and solving general pipe joint, the utility model provides a kind of high-pressure water pipe swivel joint, this joint can not only satisfy change that low viscosity fluid flows to and two of rectangular connections between connection needs when relative rotation or swing are arranged, and can be under the following hyperbaric environment of 32MPa proper functioning, and it is easy for installation, it is little to take up room, life-span is long, rapid operation, there are not characteristics such as leakage, the technological scheme of its solution is, the welding pipe nipple fixedly is housed on the swivel joint housing, on the welding pipe nipple external diameter screw thread is arranged, mandrel inserts in the swivel joint housing, the O type circle that sealing O type circle back-up ring is housed between mandrel and swivel joint housing inner face and is stacked, the location adjustment hole is arranged on the mandrel, when the utility model uses, not only changing tube fluid flows to, and can satisfy connection needs when relative rotation is arranged between the rectangular link, and can under hyperbaric environment, work, make fire-fighting equipment when needs are put out a fire, significantly reduce readiness time, and can move arbitrarily with the size of burning things which may cause a fire disaster area, for valuable time has been won in fire extinguishing.
Four, description of drawings
Accompanying drawing is a structural profile plan view of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Provide by accompanying drawing, the utility model is that welding pipe nipple 6 fixedly is housed on the swivel joint housing 5, on welding pipe nipple 6 external diameters screw thread 10 is arranged, mandrel 2 inserts in the swivel joint housing 5, the O type circle 4 that sealing O type circle back-up ring 3 is housed between mandrel 2 and swivel joint housing 5 inner faces and is stacked has location adjustment hole 1 on the mandrel 2; Welding pipe nipple 6 is fixed by welding in swivel joint housing 5; Screw thread 10 on welding pipe nipple 6 external diameters is used for being connected with other interface tubes; In order to guarantee that mandrel 2 inserts in the swivel joint housing 5, the relative position of maintenance and swivel joint housing 5 has packing ring 7 and circlip 8 on the outer end shoulder of its swivel joint housing 5; In order to be used for the location, position at the capstan winch stent support running shaft of fire-fighting equipment, the center, outer end has the cooperation auxiliary hole 9 that cooperates location adjustment hole 1 on the mandrel.
The utility model in use, mandrel 2 is connected with the capstan winch running shaft in the fire-fighting equipment, there is screw thread 11 to be connected on the one end external diameter of mandrel 2 with the hose connection that brings out from high-pressure plunger pump one, welding pipe nipple 6 links to each other with mobile capstan winch on the fire-fighting equipment, the input high pressure water is used for fire extinguishing to the spray wheel of fire-fighting equipment.
By above-mentioned situation as can be known, the utility model is fixed tube joint of welding on joint body, as fixing (moving) sebific duct capstan winch interface, the pipeline interface of another direction cooperates with joint body with a rotatable mandrel, form rotatable pipeline interface, mandrel is by shoulder and sliding mats keeps and the relative position of joint body, gapped can the rotation, and sealing guarantees by the seal ring that is enclosed within joint fuse external diameter, so not only can change tube fluid flows to, and can satisfy connection needs when relative rotation is arranged between the rectangular link, and can under hyperbaric environment, work, make fire-fighting equipment when needs carry out fire-fighting work, significantly reduce readiness time, and can move arbitrarily with the size of burning things which may cause a fire disaster area, for valuable opportunity has been won in fire extinguishing, it is applied and must make outstanding contributions for the loss that the minimizing fire causes.
