Abstract

A micro-irrigation capillary-level flow regulator, which includes a shell, a core body and an elastic film, and the core body has water inlet and outlet holes. There are two rings with different diameters spaced along the axial direction at the water inlet, and the concave surfaces of the two rings are provided with sealing rings, and there are reverse threads at the axial space to cooperate with the compression screw cap, and there are two rings larger than The circular ring of the water outlet has a sealing ring on the concave surface of the circular ring. The regulator can be directly installed at the head of the capillary tube, which simplifies the design and installation process, saves investment, improves the uniformity of irrigation and fertilization, and prevents the shell from falling off and dripping.

Description

Micro-irrigation Capillary Level Flow Regulator

The utility model relates to a micro-irrigation capillary-level flow regulator, which is particularly suitable for flow regulation at the head of a drip irrigation belt (pipe).

ZL97214517.6 "Compensated micro-irrigation flow stabilizer", which includes a shell, the water outlet at one end of the core body is connected to the water inlet on the drip irrigation belt, and there is a rectangular groove surface at the bottom of the circle in the middle of the core body, and a semicircle under the groove surface Shaped partition, along the semicircular partition, there is an arc streamline to control the flow rate, and there is a concentric hole adjacent to the semicircular partition to communicate with the inlet and outlet holes. Its disadvantage is that the core body is composed of two parts. When the water pressure is too high, it is easy to leak from the middle of the core body, thereby causing the core body to fall off.

The task of the utility model is to propose a micro-irrigation capillary-level flow regulator whose core body is an injection-molded whole, does not fall off, does not drip, and is easy to install.

The task of the utility model is achieved in this way, it includes a shell, the water outlet at one end of the core body is connected to the water inlet on the drip irrigation belt, there is a rectangular groove surface at the bottom of the circle in the middle of the core body, and there is a semicircular partition under the groove surface , there is an arc-shaped flow line to control the flow rate along the semicircular partition, and there is a concentric hole adjacent to the semicircular partition to communicate with the inlet and outlet holes. The end is the water inlet and outlet holes, and there are two rings with different diameters at the water outlet along the axial interval. The concave surface of the two rings is provided with a sealing ring, and the axial interval is designed with a reverse direction that is tightened with the drip irrigation belt. The screw thread is matched with the reverse thread and is a compression screw cover. There are two circular rings larger than the water outlet along the axial direction at the water inlet, and the concave surface of the ring is provided with a sealing ring.

The utility model has the following effects: the regulator can be directly installed at the head of the capillary without calculation, the design and installation process is simplified, investment is saved, and the uniformity of irrigation and fertilization is improved. Capillary flow regulator.

The embodiment is described in detail in conjunction with the above drawings. The utility model is composed of a film, a core body, a screw cap 10 and a casing 12 to form a whole. The core body is set in the casing 12, and the water outlet is exposed to the casing 12. The water inlet on the core 1 is conical, along the water inlet 1 there is a water flow channel 3 leading directly to the concentric hole 4, there is a rectangular groove surface 5 in the middle of the core body, there is an arc-shaped partition in the middle of the rectangular groove surface 5, and there is an arc-shaped partition along the semicircular partition. The arc-shaped streamline that controls the flow rate, the water flow enters the water flow channel 3 from the water inlet 1 and goes straight to the concentric hole 4, and flows into the irrigation capillary from the water outlet 9 of the core through the semicircular partition. The core body of the characteristic part is a concentric shaft, and the two ends of the concentric shaft are the water inlet and outlet holes 1 and 9. There are two rings b6 and c8 with different diameters at the water outlet along the axial interval. The concave surfaces of the two rings are set The sealing ring has a reverse thread 7 that is tightened with the drip irrigation belt at the axial interval, and a compression thread cover 10 is matched with the reverse thread 7, and the compression thread cover 10 is surrounded by anti-slip ears 11, and the water inlet is along the shaft. There are two rings a2 larger than the water outlet, and the concave surface of the ring is provided with a sealing ring. In order to strengthen the overall strength of the core, the outer ring walls of the inlet and outlet 1, 9 are specially designed with reinforcing ribs. When the water outlet 9 is connected to the drip irrigation belt, the thin-walled drip irrigation belt and the core body are integrally connected by using the reverse thread 7 on the core body and the screwed screw cover 10, so that the core body and the drip irrigation belt will not fall off. Water outlet 9 also can utilize two sealing rings to directly socket the thick-walled drip irrigation pipe.
