3results about How to "Wide range adjustment" patented technology

The application provides a wide-range adjustable absorption heat pump, and relates to the field of waste heat recovery heating. The application solves the problems of poor solution flow, unimprovable load, and unsatisfied heating demand at the beginning and end of the heating period, and adopts the following scheme: a condenser is internally provided with a first water inlet and a first water outlet, a bypass valve is connected between the first water inlet and the first water outlet, the bypass valve is provided with a flow adjusting part, and the flow adjusting part is used for adjusting the opening degree of the bypass valve; an evaporator is internally provided with a waste heat water inlet and a waste heat water outlet, and is used for absorbing external waste heat; the top of the evaporator is connected to the top of an absorber through a gaseous refrigerant water pipeline; the absorber is internally provided with a second water inlet and a second water outlet, and the lower part of the absorber is connected to the upper part of a generator through a dilute solution pipeline; and the generator is heated by an external heat source to heat internal solution to boiling, and water vapor is generated. The technical scheme of the application can realize wide-range and accurate adjustment.

This invention discloses a modular missile wing connection structure with adjustable position. The structure includes a missile body to which wings are connected; four elongated rectangular planes of equal thickness are arranged at equal angles along the axial direction of the missile body, and several equally spaced rectangular grooves are formed on the elongated rectangular planes along their axial direction; a wing flange is provided at the wing root of each wing, and several equally spaced rectangular locking blocks are provided at the bottom of the wing flange; the rectangular locking blocks cooperate with the rectangular grooves to connect several wings to the missile body; the number of rectangular grooves is greater than the number of rectangular locking blocks, and the relative position of the wings is adjusted by adjusting the insertion position of the rectangular locking blocks; several wings are fixed to the missile body by binding circular retaining rings. The above-mentioned wing connection structure is easy to assemble and disassemble and is adjustable, and can adapt to different combat mission requirements.

Disclosed is an acupuncture device including a needle tube and a base. The needle tube includes an outer sleeve having a first through-hole, an inner sleeve having a second through-hole, at least a portion of which is accommodated in the first through-hole, the inner sleeve being slidable and rotatable with respect to the outer sleeve, and a spherical adjusting member coupled to the outer sleeve at a side opposite to the side where the inner sleeve is located and having a third through-hole. The base includes a horizontal portion having a plate shape with a circular hole in the center thereof and coupled to the spherical adjusting member through the circular hole, and a vertical portion extending downward from a distal end of the horizontal portion to define a space for accommodating at least a portion of the spherical adjusting member together with the horizontal portion. An inner wall of the vertical portion includes a vertical wall connected to the horizontal portion and an inclined wall extending from the vertical wall in a direction away from the spherical adjusting member. The space includes a cut corner portion adjacent to the inclined wall. The device can be used for an electroacupuncture or general acupuncture clinical randomized controlled trial.
