Abstract
The utility model relates to a work carrier type pipe joint used for fire protection spraying, which comprises dissection type work carrier bodies; sealing rings are arranged in the work carrier bodies; at least one pin clamping device is arranged on each work carrier body; the pin clamping device is composed of radial screw holes arranged on the work carrier bodies, pin clamping bodies arranged in the screw holes, and screws connected with the screw holes, wherein, the bottom surface of each pin clamping body is inosculated with the outer round surface of a connected pipeline; the pipeline is firstly clamped by the work carrier bodies, and then the pin clamping bodies are closely pressed on the pipeline by the screws to enable the pipeline and the work carrier bodies to firmly connect with each other to form integration, and therefore, the pipe joint can be directly connected with the pipeline, and secondary operation to the pipeline before connecting does not need.
Description
The utility model relates to a kind of pipe joint, particularly a kind of housing type joint that is mainly used in fire-fighting spraying.
Fire-fighting spraying has all required corrosion protective covering with the inside and outside surface of pipeline, and present fire-fighting spraying pipeline all adopts plating zinc on surface usually, and its Placement has flange connection, the ring-like connection of clamp band type, clamp band type shoulder type to connect and clamp band type is groove-shaped is connected etc.These above-mentioned Placements all will be at the end of pipeline welded flange or bulge loop, and welding has the residual or rotten rust of oxidation of welding slag unavoidably, cause shower nozzle to stop up, so it is zinc-plated all will to carry out secondary when adopting this class Placement, not only make troubles, increase operating expenses, and be difficult to thoroughly eradicate some mass defects that caused because of welding to construction.
Task of the present utility model provides a kind of housing type joint that the fire-fighting spraying pipeline connects that is mainly used in, and this pipe joint need not pipeline is welded bulge loop or convex shoulder just can directly link together zinc-plated pipeline, and does not destroy the zinc coat of pipeline again.
The solution that realizes the utility model task is: a kind of housing type joint that is provided, comprise at least two split type clip bodies, and connect with bolt between the clip body, be provided with the seal ring that matches with the connected pipe periphery in the clip body.Improvements of the present utility model are to be provided with a pin card device on each clip body at least, this pin card device by be located at the radially screw on the hoop body, the pin card body that is contained in this screw is formed with the screw that is connected with this screw, wherein the bottom surface and the connected pipe periphery of pin card body match.Pipeline is located by connecting by the clip body earlier, will sell the card body by the screw of pin card device then and be pressed on the pipeline, and pipeline and clip body are connected as a single entity securely.
Above-mentioned pin card device is preferably on each clip body and is provided with two, and they lay respectively at the both sides of clip body sealing ring, and housing type joint of two minutes is totally four pin card devices.
Compared with prior art, the utility model directly links together the finished product pipeline, has avoided pipeline to connect preceding secondary operations and zinc-plated, not only reduced difficulty of construction and expense, and quality of connection is higher, also increase to some extent the working life of pipeline, in addition, construction speed also improves a lot.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Fig. 1 is the overall structure figure of an example of the utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the plan view of Fig. 1 pin card body.
Fig. 4 is the left view of Fig. 1 pin card body.
As shown in Figure 1 and Figure 2: pipe joint is made up of split type clip body 1, connecting bolt 2, nut 3 and seal ring 4, and seal ring 4 is positioned at the middle part of clip body 1.On each clip body 1, be provided with two pin card devices 5, lay respectively at the both sides of seal ring 4, and with 2 one-tenth 90 ° of distributions of clip body connecting bolt.Pin card device 5 is made up of the screw 51, screw 52 and the pin card body 53 that are located on the clip body.The structure of pin card body 53 as shown in Figure 3, Figure 4, it is a cylindrical body, its diameter is less than the internal diameter of screw 51, its bottom surface 54 is cylndrical surface of an indent, this cylndrical surface diameter is consistent with the external diameter of connected pipe 6.To sell card body 53 during construction and put into screw 51, and compress with screw 52 again and get final product.Higher through the pipeline straightness accuracy that the advance copy model utility connects, the ability of bearing axial force is also higher, complies with relevant regulations fully.
Claims (2)
1, a kind of housing type joint, comprise at least two split type clip bodies (1), connect with bolt (2) between clip body (1), be provided with the seal ring (4) that matches with the connected pipe periphery in the clip body (1), it is characterized in that on each clip body (1), being provided with at least a pin card device (5), this pin card device is made up of with the screw (52) that is connected with this screw the pin card body (53) that is located at radially screw (51) on the hoop body, be contained in this screw, and wherein the pin bottom surface and the connected pipe periphery that block body (53) matches.
2, pipe joint as claimed in claim 1 is characterized in that each clip body is provided with two pin card devices, and lays respectively at the both sides of clip body sealing ring (4).
