Abstract
The utility model provides a blowout-preventing cap for oil pipes, which comprises a handle (1), a blowout-preventing cover (2), a connecting rod (3) and a screwed plug (4), and is characterized in that a through-hole for communicating the bottom end thereof with the lateral wall thereof is formed on the screwed plug (4); and the blowout-preventing cover (2) is mounted on the connecting rod (3). The blowout-preventing cap of the utility model has the advantages of simple structure and convenient use, and is capable of preventing the oil in the oil pipes from overflowing and spilling in all directions, thus providing convenience for construction and avoiding environmental pollution.
Description
Technical field: the utility model relates to a kind of oil field workover instrument, especially for a kind of oil pipe anti-gushing cap of underground work.
Background technology: before the utility model, the oil pipe overflow takes place in each oil field regular meeting in underground work, and makes troubles to construction owing to splash everywhere, and may cause environment pollution to a certain degree.
Summary of the invention: the purpose of this utility model is: for oilfield downhole operation provides a kind of oil pipe anti-gushing cap, because this device can be installed in the tubing string top and have spray guard, thereby can prevent oil pipe overflow splash everywhere, and not only made things convenient for construction, also can avoid pollution on the environment.
The purpose of this utility model realizes by following measure: a kind of oil pipe anti-gushing cap, constitute by handle, spray guard, connecting rod, plug, and plug upper end installation one has the connecting rod of handle, it is characterized in that being processed with the open-work that can be communicated with its bottom and sidewall on the plug, and a spray guard that falls bowl-type is installed on connecting rod.
The utility model is simple in structure, easy to use, can prevent oil pipe overflow splash everywhere when being used for underground work, not only brings convenience to construction, also can avoid pollution on the environment.
Description of drawings: Fig. 1 is the structural representation of oil pipe anti-gushing cap.
The specific embodiment: the oil pipe anti-gushing cap is made of handle 1, spray guard 2, connecting rod 3, plug 4 etc., plug 4 upper ends installation one has the connecting rod 2 of handle 1, one spray guard 2 that falls bowl-type also is installed on the connecting rod 2, is processed with the open-work that can be communicated with its bottom and sidewall on the plug 4.
The operating principle and the using method of oil pipe anti-gushing cap are: in the underground work process as the oil pipe overflow takes place, can plug 4 be screwed in the tubing string top by handle 1, the interior overflow of tubing string this moment just can be guided to by the open-work on the plug 4 in the spray guard 2, and along its inwall whereabouts, thereby prevented splash everywhere, made things convenient for construction, also can avoid environment is polluted.
