TECHNICAL FIELD
[0001] The utility model belongs to laboratory water nozzle technical field relates to a laboratory double water nozzle, especially is a laboratory rotary folding double water nozzle. BACKGROUND
[0002] Traditional laboratory double water nozzle is mostly fixed type, cannot rotate or fold, and the water taking position is fixed, so the water taking space is limited. The water taking appliance needs to be moved to the fixed position below the water nozzle to take water. If the water taking appliance is large and inconvenient to move, a small amount of cups or other tools need to be used to take water multiple times. In addition, when using two water nozzles to take water at the same time, if the water taking appliance is large, the two appliances are easy to interfere with each other, which causes the two water nozzles to be unable to be used at the same time, and the practicability of the double water nozzle is seriously reduced. Therefore, it is necessary to provide a laboratory double water nozzle which can rotate, fold and adjust direction to facilitate application in the experiment. SUMMARY
[0003] The utility model aims at providing a laboratory rotary folding double water nozzle to solve the technical problems of position fixation, limited water taking space and poor practicability in the prior art.
[0004] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows:
[0005] A laboratory rotary folding double water nozzle comprises a main water pipe, a tee joint, a horizontal rotary joint, a vertical rotary elbow, a water outlet branch pipe and a water outlet elbow pipe. The main water pipe is vertically arranged. The tee joint is connected to the upper end of the main water pipe. The number of the horizontal rotary joint, the vertical rotary elbow, the water outlet branch pipe and the water outlet elbow pipe is two respectively. The two horizontal rotary joints are connected to the two ends of the tee joint respectively. The two vertical rotary elbows are connected to the two horizontal rotary joints respectively. The two water outlet elbow pipes are connected to the two vertical rotary elbows through the two water outlet branch pipes respectively. The water outlet elbow pipe and the water outlet branch pipe have the freedom of rotation around the axis of the water outlet branch pipe. The water outlet elbow pipe, the water outlet branch pipe and the vertical rotary elbow have the freedom of swing around the axis of the horizontal rotary joint.
[0006] The two vertical rotary elbows are left-handed elbow and right-handed elbow respectively. The left-handed elbow is connected to the horizontal rotary joint on the left side of the main water pipe. The right-handed elbow is connected to the horizontal rotary joint on the right side of the main water pipe.
[0007] The thread length of the left-handed elbow and the right-handed elbow is consistent.
[0008] A stop valve and a porcelain core handwheel assembly are arranged on the water outlet branch pipe. The water outlet elbow pipe is fixedly connected to the water outlet branch pipe through the stop valve and the porcelain core handwheel assembly. The water outlet end of the water outlet elbow pipe is connected to a water outlet nozzle.
[0009] The water outlet pipe is sealed to the longitudinal rotating elbow by lock nut A, sheath, and rubber ring A.
[0010] The longitudinal rotary elbow and the transverse rotary joint are sealed together by a rubber ring B and a damping washer.
[0011] The main water pipe is sealed to the external water supply pipe through lock nut B, lock nut gasket and rubber ring C.
[0012] The beneficial effects of this utility model are as follows: By providing a laboratory rotating folding double water tap, and by sequentially connecting a transverse rotating joint and a longitudinal rotating elbow to both sides of the tee, the water outlet bend can not only rotate 360° around the axis of the water outlet pipe, but also around the axis of the transverse rotating joint. This design greatly expands the coverage space of the water outlet bend end, allowing for easy adjustment of the water outlet bend position for water connection as needed. Furthermore, when two large water-connecting instruments need to be connected simultaneously, the angle of the water outlet bend can be adjusted to prevent interference between them, thereby improving the practicality of the double water tap and facilitating its full utilization during experiments.
