Abstract
The utility model belongs to the joint fitting of a water supplying cast iron pipe, which relates to a technology fitting-an active join wheel which is used for the first-aid repair of the cast iron pipe of a water supplying, conveying and distributing pipe. The utility model is composed of a screw bolt, a flange press cover, a pipe body and a sealing rubber ring and is characterized in that the sectional plane of the pipe body forms a 'K' shape, one end of the pipe body is connected with the flange press cover through the screw bolt, and the sealing rubber ring are arranged on the joint opening point between the pipe body and the flange press cover. The utility model provides the first-aid repair of the cast iron pipe of the water supplying, conveying and distributing pipe in the water supplying industry with the first-aid repair technology fitting-the active join wheel which can carry out maintenance operation with water and operate simply. In the maintenance operation, the labor intensity of workers is lightened, and the work efficiency is enhanced. Compared with the traditional maintenance method of calking an opening in a broken pipe, the utility model has the advantages of time saving, material cost saving and excavation cost saving. The utility model can also be used in the connection of pipe pieces such as water meters with large calibers, water gates, etc., and has the advantages of convenient replacement, low cost and safe use.
Description
Technical field the utility model belongs to water supply cast iron pipe joint accessory, relates to the leak process kit Active join wheel of repairing of a kind of water distribution pipeline cast iron tube that is used to supply water.
Background technique is present, domestic in water supply industry because the cast iron tube cost is low, corrosion resistance is strong, therefore in the water supply water-supply pipeline is installed, be widely used.But cast iron tube exists, and fragility is strong, anti-pressure ability is weak, the shortcoming of frangibility, therefore in the water supply field, because of the fracture situation of leaking of cast iron tube very general.Traditional emergency repairing technology method is to adopt disconnected pipe to beat a mouthful method for maintaining, its complex procedures, cost height, labor strength are big, disconnected pipe, plug fiber crops, change plumbous, beat operation technical requirements height such as mouth, cut off the water and also may produce the danger that quick-fried lead is hurted sb.'s feelings when tight, sometimes also need large size to cut off the water, cause maintenance work heavy, also influenced normal life of citizen and process water.
The summary of the invention the purpose of this utility model is to provide a kind of with water maintenance operation, emergency repairing technology accessory Active join wheel easy and simple to handle for the repairing of leaking of water supply water distribution pipeline cast iron tube in the water supply industry.
The utility model Active join wheel content Description:
The utility model Active join wheel, by: bolt, flange gland, body, O-ring seal are formed, it is characterized in that: the section of body is for " K " shape, and an end of body is connected by bolt with the flange gland, at the jointing of body and flange gland O-ring seal is set.
The utility model has alleviated working strength of workers widely, has improved working efficiency for the repairing of leaking of water supply water distribution pipeline cast iron tube in the water supply industry provides a kind of with water maintenance operation, emergency repairing technology accessory Active join wheel easy and simple to handle in maintenance operation.Beat a mouthful method for maintaining with traditional disconnected pipe and compare, disconnected pipe beat mouthful method for maintaining approximately need 2～3 hours, Master Cost need 1300 yuan, work surface is approximately 6～8M
2, and adopt the Active join wheel maintenance only to need 20～40 minutes, and Master Cost needs 420 yuan, and work surface is about 1～2M
2, have the advantages that to save time, save Master Cost, save excavation cost.Traditional disconnected pipe needs health 12～24 hours when beating a mouthful method for maintaining and beating cement port, and Active join wheel gets final product water flowing after installation, and anti-vibration is a flexible interface.The utility model Active join wheel can also be applied in the connection of pipe fittings such as large-diameter water meter, water valve, have and change convenient, cheap, safe and reliable characteristics, the enforcement of the utility model patent is with the economic benefit and the social benefit of favourable raising water supply industry.
Description of drawings Fig. 1 is the Active join wheel structural representation
Among the figure: 1 is that bolt, 2 is that flange gland, 3 is that body, 4 is O-ring seal
Embodiment the utility model Active join wheel is achieved in that sees Fig. 1, and the section of body 3 is " K " shape, and an end of body 3 is connected by bolt 1 with flange gland 2, at the jointing of body 3 and flange gland 2 O-ring seal 4 is set.Tighten flange gland 2 with bolt 1 in use, crush seal cushion rubber 4 makes O-ring seal 4 modification closed interface sealings.When water supply water-supply pipeline maintenance and installation, need two Active join wheels, two O-ring seals, two flange glands, earlier the cast iron tube that fractures is cut off, the length of the disconnected pipe of requirement must not surpass the length of Active join wheel, then flange gland, O-ring seal, Active join wheel be inserted in successively disconnected pipe both sides, tight a bolt at last till do not drip.
