Abstract
The utility model discloses a sliding pneumatic driver. The sliding pneumatic driver comprises a connecting rod (1), a sealing piece (2), a lower cover (3), a sealing mechanism (4), a cylinder (5), an overload protector (6), an upper cover (7), interfaces (8), a nut (9) and a spring (10), wherein two interfaces (8) are arranged on the upper cover (7); one of the interfaces is connected with a pressure source; the other one of the interfaces is connected with the overload protector (6); the upper cover (7) is welded with the cylinder (5); the sealing mechanism (4) is arranged in the cylinder (5); the connecting rod (1) is arranged in the center of the sealing mechanism (4) by the nut (9); the lower cover (3) is arranged on the cylinder (5); the connecting rod (1) is sleeved by the spring (9), penetrates through the lower cover (3) and is sealed by the sealing piece (2); and sliding double chambers are formed in the cylinder (5) between the upper cover (7) and the lower cover (3) by the sealing mechanism (4). The sliding pneumatic driver has a simple structure, corrosion and washing in a hydraulic mode are avoided, maintenance time is prolonged, and service life is prolonged.
Description
Technical field
The utility model belongs to well head oil recovery (gas) tree control system and pipeline control, relates to the executing agency that is widely used in adopting defeated well head Long-distance Control valve switch action, is specifically related to a kind of slidingtype air impeller.
Background technology
As everyone knows, driver is a kind of executing agency that is applied to adopt defeated well head Long-distance Control valve switch action, at present, the driver that use in the known oil field pattern Execution driven that is mostly to surge requires material to have the ability of higher decay resistance and antiscour rate, and the seal member replacement cycle is short, increased maintenance cost, reduced oil recovery efficiency, when not allowing to change driver under special operation condition, this fault will affect the work of whole well head or pipeline.
Summary of the invention
The purpose of this utility model is: a kind of slidingtype air impeller is provided, and simple in structure, with low cost, easy to maintenance, reduce the wearing and tearing of sealing mechanism, avoid by liquid corrosion, improve the application life of driver.
Technical solution of the present utility model is: this driver comprises connecting rod 1; seal 2; lower cover 3; sealing mechanism 4; cylinder body 5; overload protective device 6; loam cake 7; interface 8; nut 9 and spring 10; establish two interfaces 8 on the loam cake 7; one of them interface connects pressure source; another interface is taken over and is carried protector 6; loam cake 7 is welded on the cylinder body 5; cylinder body 5 interior installation sealing mechanisms 4; middle the heart channel of Hang-Shaoyin nut 9 of sealing mechanism 4 is installed connecting rod 1; lower cover 3 is installed on the cylinder body 5; pass lower cover 3 behind connecting rod 1 pocketed springs 10 and sealed the two-chamber that the cylinder body 5 interior formation of sealing mechanism 4 between loam cake 7 and lower cover 3 are slided by seal 2.
The utlity model has following advantage:
1, it is pneumatic driving execution pattern, and the corrosion of the pattern of having avoided surging and washing away improves application life greatly;
2, simple in structure, easy to process, cost of production is low;
3, need bleed pressure low, adopt multi-sealedly, sealing effectiveness is better.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 connecting rod, 2 seals, 3 lower covers, 4 sealing mechanisms, 5 cylinder bodies, 6 overload protective devices, 7 loam cakes, 8 interfaces, 9 nuts, 10 springs.
The specific embodiment
As shown in Figure 1; this driver comprises connecting rod 1; seal 2; lower cover 3; sealing mechanism 4; cylinder body 5; overload protective device 6; loam cake 7; interface 8; nut 9 and spring 10; establish two interfaces 8 on the loam cake 7; one of them interface connects pressure source; another interface is taken over and is carried protector 6; on the loam cake 7 welding cylinder bodies 5; cylinder body 5 interior installation sealing mechanisms 4; middle the heart channel of Hang-Shaoyin nut 9 of sealing mechanism 4 is installed connecting rod 1; lower cover 3 is installed on the cylinder body 5; pass lower cover 3 behind connecting rod 1 pocketed springs 10 and sealed the two-chamber that the cylinder body 5 interior formation of sealing mechanism 4 between loam cake 7 and lower cover 3 are slided by seal 2.
During unlatching, inject air pressure, air pressure promotes sealing mechanism 4 down slidings, and it is mobile together that sealing mechanism 4 drives connecting rod 1, until sealing mechanism 4 slides into lower cover 3, finishes once and opens; When closing, shed pressure source, can finish closure.
