Abstract
The utility model discloses an oilfield balanced type cut-off valve, which relates to a cut-off valve for using the oil transport pipeline in oilfield. The oilfield balanced type cut-off valve mainly solves the problem that the cut-off valve cut off the transport pipeline arduously, the sealing effect is influenced by the cut-off valve in exist oil transport pipeline. The oilfield balanced type cut-off valve comprises a valve body, a valve flap, a sealing sleeve, a valve lever, a filler, a valve cover, a valve-stem nut, a thrust bearing and a handle. The valve flap adopts the structure of the plunger type, a via hole is arranged in the valve flap, and an upper chamber is arranged between the sealing sleeve and the valve flap. The utility model has the advantage of switch labour-saving; the oilfield balanced type cut-off valve is benefit to seal.
Description
Technical field: the utility model relates to a kind of oil field oil transport pipeline stop valve.
Background technique: owing to be subjected to the influence of pressure medium, close effort when existing oil field oil transport pipeline is worked with stop valve, influence sealing effect, particularly middle and high pressure valve, problem is more outstanding.
Summary of the invention: the purpose of this utility model provides the oil field balanced type stop valve of the laborsaving and good sealing effect of a kind of switch.
Above-mentioned purpose is achieved in that it comprises valve body, flap, stuffing box gland, valve rod, filler, valve gap, Stem Mut, thrust-bearing and handle, the flap here adopts plunger-type structure, in flap, establish through hole, between stuffing box gland and flap, establish the flap epicoele.Advantage is that medium flows into the flap epicoele by valve body through the through hole in the flap when flap rises, and makes valve body and flap upper cavity pressure balance, so the switch non-resistance, and switch is laborsaving, and favourable sealing.
Description of drawings: accompanying drawing is a generalized section of the present utility model.
Embodiment: flap 2 and stuffing box gland 3 are contained in the valve body 1, valve rod 4 is connected with flap and seals with filler 5, valve gap 6 is contained on the valve body, Stem Mut 7 is contained in the upper end of valve gap, thrust-bearing 8 is contained on the Stem Mut, and handle 9 is connected with Stem Mut, and flap adopts plunger-type structure, in flap, establish through hole, between stuffing box gland and flap, establish flap epicoele 10.
