Abstract

The invention discloses a double-stop discharge needle-shaped valve which comprises a valve body inlet, a main stop valve and a needle-shaped valve, wherein a main valve body is provided with the valve body inlet which is connected with an internal pipeline interface; an internal pipeline is provided with three interfaces, and the other two interfaces are respectively connected with one end of the needle-shaped valve and one end of a secondary stop valve; the other end of the needle-shaped valve is connected with a main discharge hole, and the other end of the secondary stop valve is connected with a secondary discharge hole; and the main stop valve is provided with a flange self-locking device. The double-stop discharge needle-shaped valve has the beneficial effects being simple in structure, low in production cost and diversified in valve control functions, and guaranteeing the safety of the valve due to the self-locking device.

Description

technical field [0001] The invention relates to a double cut-off and discharge needle valve, in particular to a double cut-off and discharge needle valve. Background technique [0002] The globe valves in the existing market have a single function in actual use and do not meet the diversified actual production requirements in modern production, which brings great inconvenience to practical applications. Contents of the invention [0003] Aiming at the disadvantages of the existing needle valves, the invention provides a novel multi-double cut-off and discharge needle valve. [0004] In order to achieve the above object, the measures taken by the present invention [0005] A double cut-off and discharge needle valve, including a valve body inlet, a main cut-off valve, and a needle valve. The main valve body is provided with a valve body inlet, and the valve body inlet is connected to a built-in pipeline interface; the built-in pipeline is provided with three interfaces. T...
