Description

A kind of swiveling faucet that is used for rig

Technical field

The utility model belongs to the plant equipment field, is specially a kind of swiveling faucet that is installed on the rig power output shaft.

Background technology

Water tap mainly works to carry water under high pressure mud in rig, during work, water under high pressure mud is transported to borer drill rod heart portion by high-pressure water tap, and reach by drilling rod at the bottom of the hole of earth drilling, jet apertures by drilling rod bottom perfusion mud is flushed to high-pressure slurry in the stratum again, when constantly washing, rotary drill rod makes high-pressure slurry and drill bit constantly cut rock-soil layer all around.Slowly at the uniform velocity landwaste is risen to ground with mud when flushing mud, constantly such construction just can form boring.

Because the seal of water tap can bear the high speed rotary grinding of huge pressure and core pipe in work progress, this makes that the water tap sealing part abrasion can be very fast.In present employed high-pressure water tap, the housing of high-pressure water tap outside all is to adopt fixedly connected mode, particularly because the housing of high-pressure water tap front end is fastening, this makes that the dismounting difficulty is very big when changing the housing accessory, require a great deal of time and dismantle the accessory that is worn, spend long time to refill new seal fitting then again, stopped over the plenty of time during owing to the replacing accessory, this makes that the spudder does to be difficult to continue carry out.

The utility model content

At above-mentioned deficiency of the prior art, the purpose of this utility model is to solve the water tap installed on the rig bigger problem of dismounting difficulty when changing seal fitting, so a kind of convenient disassembly is provided, easier and can regulate the swiveling faucet of wearing and tearing at any time when changing abrasive element.

The technical solution of the utility model: a kind of swiveling faucet that is used for rig, it is characterized in that, comprise water supply connector, seal receptacle, core barrel and be enclosed within transmission mechanism on the described core barrel; Water inlet pipe in described water supply connector and the seal receptacle is communicated with, also be provided with hollow connector in seal receptacle, an end of described connector is communicated with water inlet pipe, and the other end is connected with core barrel by adapter sleeve, one side and the connector of described adapter sleeve are fixed, and opposite side is threaded with core barrel; The bearing support that described transmission mechanism comprises transmission housing and the gland that is enclosed within the core barrel front end and is enclosed within the core barrel middle part, the inner chamber of described transmission housing is communicated with the formation intake tunnel successively with the inner chamber of core barrel, connector, water inlet pipe and water supply connector, between transmission housing and core barrel, be provided with combined seal ring, one end of described transmission housing is a delivery port, and the other end is fixedlyed connected with gland; The front end and the gland of described bearing support are fixed, in bearing support, be provided with fore bearing body and rear bearing body, on the core barrel between fore bearing body and the rear bearing body, also be provided with a positive stop lug boss, described fore bearing body is limited between the sidewall and positive stop lug boss of bearing support front end, and described rear bearing body is limited between the sidewall and positive stop lug boss of bearing support rear end.

With respect to prior art, the utlity model has following beneficial effect:

Swiveling faucet of the present utility model has dismounting, advantage easy for installation, because the water tap front end has adopted bolted mode to fix because of the frequent transmission housing of changing of the bigger need of wearing and tearing, therefore wearing and tearing that can adjustment housings, and when changing accessory, the parts that are worn directly can be dismantled, again new accessory is got final product with bolt, therefore whole replacing process time is very short, operates also very simply, can next step drilling well work not occasioned a delay; A parts (transmission housing) to serious wear on the water tap changes the outfit during simultaneously owing to replacing, and therefore discarded component are less, thereby can reduce the cost of parts of consumption, reduced the waste of resource.And, owing to be provided with combined seal ring between transmission housing and the gland, just can strengthen the pretightning force of combined seal ring by the position of manual adjustments transmission housing, reach preferable sealing effectiveness; Simultaneously, after combined seal ring is by the part wearing and tearing, can also compresses sealing ring by screwing the transmission housing, thereby help reducing of the harmful effect of combined seal ring wearing part sealing effectiveness.
