Description
Technical field
The utility model relates to the high pressure pipe line valve, relates in particular to a kind of two flange end valves that integrate ball valve, needle-valve.
Background technique
Two by the double functions such as the injection of valve collection chemical industry, flow control, pressure control, sampling of putting, be that the high pressure pipe line device must obligato staple product.Twoly comprise ball valve, needle-valve (instrument needle-valve) etc. by the double valve of putting, ball valve has medium and returns zero function by, adverse current, pressure gauge, needle-valve play bleed off sampling pressure measurement with along separate routes and functions such as configuration transmitter.In the existing high pressure pipe line valve, ball valve and needle-valve are that split is provided with structure, and this split is provided with structure and has the structure absent-mindedness, and assembly process complexity, potential leakage point are many, defectives such as fabricating cost height.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of compact structure, and potential leakage point is few, manufactures lower-cost integral double flange combined ball needle valve, to overcome the existing body structure high pressure pipe line defective that valve exists of dividing.
The technological scheme that the utility model adopted is: a kind of integral double flange combined ball needle valve, comprise valve body, valve body is by flange connections road, integral type two ends, arrange two straight-through valves on the described valve body, the spheroid of two ball valves places valve body, first ball valve is connected with the first flange end cap that is installed in the valve body left side, second ball valve is connected with the second flange end cap that is installed in valve body the right, two ball valve neutral positions of valve body are provided with the instrument needle-valve, the lower end of valve body is a bleed outlet, and bleed outlet can be the internal thread bleed outlet of band plug device.Medium enters first ball valve by the first flange end cap import, instrument needle-valve and plug play bleed off sampling pressure measurement with along separate routes and effects such as configuration transmitter, first ball valve is total stop valve, second ball valve returns zero function as the attached medium of doing by, adverse current, pressure gauge.This combined ball needle valve has two by double playing function.
The beneficial effects of the utility model are: because different three the independent valve combination of function are integrated, has compact overall structure, solid, reduced a large amount of potential leakage points, advantages such as cost are manufactured in saving, can be equipped with multiple different connecting end equipment, functions such as the injection of collection chemical industry, flow control, pressure control, sampling are that the high pressure pipe line device must obligato staple product.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
