(57) Abstract:In the shower nozzle turbine made with G-shaped blades and installed in one of the cylindrical chambers. The blades of one of the shelves facing the wall, and a bottom with holes installed in a different camera. Pipe for liquid inlet provided with a partition dividing the fluid into two streams, and a valve, installed in front of the wall. Fluid supply is performed in both cameras at the same time a pipe with a partition and a valve, installed in front of the wall. Turn the faucet to regulate both the flow of liquid coming into the camera. In this shower nozzle at a constant flow rate by turning the valve is regulated by the rotational speed of the turbine and thereby adjusts the frequency of the pulsations of the fluid. 2 Il. The invention relates to a device for spraying liquid, and whirlpool.The famous shower head , comprising a cylindrical housing with a tangential liquid inlet, a partition dividing the casing into two chambers and mounted perpendicularly to the axis of the vortex hole in the wall connecting the two chambers and outlet openings in the bottom of the shower nozzle.The disadvantages of this shower does Wirayuda at a constant flow rate.A device for pulsed fluid , containing a cylindrical housing with two chambers separated by a partition, installed perpendicular to the axis of the housing, the shaft passing through the wall at one end of which a disk with holes, and at the other end of the blade. The disk with the holes located in the outlet chamber, and vanes in the other. The input fluid is in the input chamber and the output of the fluid occurs from both cameras. From the exit chamber, the liquid is supplied to the object of influence, and through openings in the partition is served on the blades in the other chamber and causes the rotation of the shaft with the disc.The disadvantage of this device is that only part of the liquid is supplied to the object of exposure, and the frequency of the pulsations of the fluid depends on the amount of liquid supplied to the device. Impossible adjusting the frequency of the pulsations of the fluid at constant flow.The objective of the invention is to provide a shower nozzle with adjustable frequency pulsations of the fluid during its flow is constant.For this turbine with blades that are both and gates for openings in the partition, installed in one chamber, and a bottom with holes DL the full-cock, which changes the ratio of flows of the fluid supplied to both cameras at the same time.In Fig. 1 shows a General view of the shower nozzle, and Fig. 2 is a view along arrow a in Fig. 1.Shower head consists of a cylindrical body 1, partition 2 with holes 3, a turbine 4 with G-shaped blades 5, a bottom 6 with holes 7. Fluid supply is performed by a pipe 8 with the partition 9 and the valve 10.Shower head operates as follows.Fluid through the valve 10 is served in both cameras simultaneously. In both chambers, the nozzle has a tangential entry. Fluid entering the chamber, curls and creates a ripple. The fluid flow entering the chamber with the turbine 4, causes the latter to rotate. Moreover, the frequency of rotation of the turbine depends on the amount of fluid passing through the chamber. L-shaped blades 5 open and close the apertures 3 in the partition 2, the formation of the pulsation of the fluid, which can be adjusted. Adjusting the flow of liquid at its constant flow rate through the shower head by turning the faucet 10. Shower head containing cylindrical body and a bottom with openings for exit of fluid, a partition with holes, rathdune made with G-shaped blades and installed in one chamber, moreover, the blades of one of the shelves facing the wall, and a bottom with holes mounted in the other chamber, a nozzle provided with a partition dividing the fluid into two streams, and a valve, installed in front of the wall.
FIELD: oil and gas industry.
SUBSTANCE: in end piece, flow conic slit-like channel of variable section is made screwed with rotation of longitudinal axis for angle 20-60°. Section at output is decreased in comparison to input in 1.5-3 times.
EFFECT: higher efficiency.
