Abstract
The utility model relates to a split pressurized pipe joint, comprising a joint body, a sealing ring and a clamp sleeve. The joint body is provided with a radial split structure type and an axial split structure type. The joint body of the radial split structure is composed of an inner sleeve of a core body and outer sleeve which are connected, and inner screws of the outer sleeve are matched and connected with outer screws of the inner sleeve. The joint body of the axial split structure is composed of a big end core body, a small end core body provided with a connecting outer sleeve and a sealing washer; the small end core body is provided with a washer groove, and the outer screws on the front end are matched and connected with the inner screws of the big end core body. The utility model has the advantages of favorable part manufacturing performance, copper material saving and low manufacture cost, and the sealing property and the connecting reliability can completely meet the operating requirements.
Description
The utility model relates to the pipe joint technical field, particularly a kind of split type forcing pipe joint.
Existing a kind of plastic-aluminum combined effective pressured type pipe joint as shown in Figure 1, it is made up of joint body 1, seal ring 3, chuck 2, joint body 1 adopts overall structure, be applied to when this pipe joint on the pipe of big specification, its manufacturing cost is higher, the used die casting mould life-span is shorter, is unfavorable for applying of aluminium-plastic composite pipe.
The purpose of this utility model is to provide a kind of easy to process, split type forcing pipe joint that manufacture cost is lower.
The purpose of this utility model is achieved in that a kind of split type forcing pipe joint, comprises joint body, seal ring, chuck, and described joint body adopts radially split-type structural or axially split-type structural.Described split type forcing pipe joint, described joint body is made up of cover, connection overcoat in the core body, and described connection overcoat inner chamber is provided with internal thread, and the cover intermediate section is provided with outside thread in the core body, and above-mentioned internal and external screw thread is connected.Described split type forcing pipe joint, described joint body is made up of small end core body and gasket seal that big end core body, band connect overcoat, and the small end core body is provided with spacer groove, and its front end is provided with outside thread, big end core body inner chamber rear portion is provided with internal thread, and above-mentioned internal and external screw thread is connected.
Advantage of the present utility model is that the part processing performance is good, economical with materials, low cost of manufacture, and its sealing, connection reliability also satisfy usage requirement fully.
Fig. 1 is existing a kind of plastic-aluminum combined effective pressured type pipe joint structure schematic representation.
Fig. 2 is radially split type forcing pipe joint structure schematic representation of the utility model embodiment 1.
Fig. 3 is a parts explosion shown in Figure 2.
Fig. 4 is axial split type forcing pipe joint structure schematic representation of the utility model embodiment 2.
Fig. 5 is a parts explosion shown in Figure 4.
By following embodiment the utility model is further elaborated.
Embodiment 1:
Referring to Fig. 2, shown in Figure 3, the radially split type forcing pipe joint of embodiment of the utility model is made up of joint body, chuck 22, seal ring 23, and joint body is made up of cover 212 in connection overcoat 211, the core body, connect overcoat 211 inner chambers and be provided with internal thread 2111, cover 212 is a hollow cylinder in the core body, its intermediate section is provided with outside thread 2121, be connected overcoat 211 on internal thread 2111 be connected, the inboard that connects overcoat 211 is provided with the annular groove 2112 that matches with chuck 22.Substantially be covered with zigzag fashion annular groove 2122 on cover 212 outer cylinders in the core body, and be provided with many closure gasket grooves 2123 at a certain distance, O RunddichtringO 23 is enclosed within each bar closure gasket groove 2123.To be connected to diameter identical or diameter is different but during comparatively approaching pipe, can take this split scheme when these pipe joint two ends.Because cover 212 is more or less the same with the inside and outside footpath that is connected overcoat 211 in the core body, adds man-hour, available hollow copper tubing material is processed, thus the processing cost of greatly reducing.During assembling, the threaded connection place that connects cover 212 in overcoat 211 and the core body can add a little adhesive bond, in case both are loosening in the future.
Embodiment 2:
Referring to Fig. 4, shown in Figure 5, the axial split type forcing pipe joint of another embodiment of the utility model is made up of joint body, chuck 22, seal ring 23, joint body is by connecting overcoat 211, holding core body 213, small end core body 214 and gasket seal 215 to form greatly, small end core body 214 is a monolithic construction with being connected overcoat 211, connect overcoat 211 and be provided with spacer groove 2113, in order to place gasket seal 215; Small end core body 214 front ends are provided with outside thread 2141; Big end core body 213 inner chamber rear portions are provided with internal thread 2131, and with outside thread 2141 screw-thread fit of small end core body 214.All the other structures are identical with embodiment 1.Above-mentioned split type scheme is applicable to that the pipe joint diameter of joining two pipes together in two ends differs bigger situation.Because length dimension is little, the 214 suitable die-casting processes of small end core body hold core body 213 to be processed by the hollow copper tubing material greatly.
Shown radially split type forcing pipe joint and the axial split type forcing pipe joint of above-mentioned two examples is equally applicable on the joints such as threeway, elbow.
