Abstract
The utility model discloses an intercepting valve body which comprises a cylinder body. The upper end of the cylinder body is provided with at least two convex edges which are raised outwards, and the convex edges are evenly distributed along the circumference of the cylinder body; at least two convex ribs with opposite positions are arranged on the outer wall of the cylinder body; a support frame is arranged on the inner wall of the cylinder body; the center of the support frame is provided with a run-through screwed hole in which a threaded rod is screwed; the upper end of the threaded rod is provided with a gland bush; an obturating ring is arranged on the gland bush at the contacting part with the cylinder body; and the upper surface of the gland bush is provided with a concave hole. Duo to the adoption of the screw gland bush, the utility model can well control the irrigative water quantity, and is convenient to replace the gland bush; the convex ribs arranged on the outer wall of the cylinder body can prevent the cylinder body from rotating after being embedded underground.
Description
Technical field
The utility model belongs to sprinkling irrigation equipment, relates in particular to the Fluid cutting-off valve body of a kind of farmland sprinkling irrigation.
Background technology
The Fluid cutting-off valve body that the Fluid cutting-off valve body of the usefulness of field sprinkling irrigation at present mostly adopts metal material to make, this valve body be embedded in underground be corroded easily bad, influence Fluid cutting-off valve body service life, and shower head can not adjust direction after being installed on the Fluid cutting-off valve body again, be subjected to certain restriction when spraying.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of easy to install and use, solid and reliable, good seal performance is provided, be difficult for producing leak, Fluid cutting-off valve body that hydraulic losses is little.
The utility model is achieved through the following technical solutions:
A kind of Fluid cutting-off valve body includes cylindrical shell, and described cylindrical shell upper end is provided with the convex edge to outer lug, the inwall of cylindrical shell is provided with bracing frame, and the screwed hole of the center of bracing frame for connecting is combined with screw rod in the screwed hole, the upper end of screw rod is provided with gland, is provided with sealing ring with the cylindrical shell touching position on the gland.
Being provided with on cylinder body outer wall is few two convex tendons that the position is relative.
The quantity of described convex edge is at least two, and evenly distributes along the circumference of cylindrical shell.
The upper surface of described gland is provided with a shrinkage pool.
The utility model has the advantages that:
Because employing of the present utility model is spiral cover, can control the water yield of irrigation well, also is convenient to change gland, the convex tendon that is provided with on cylinder body outer wall is in order to prevent that cylindrical shell from rotating imbedding underground back.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the syndeton schematic diagram of shower nozzle and Fluid cutting-off valve body.
The specific embodiment
Embodiment: Fluid cutting-off valve body as shown in Figure 1, include cylindrical shell 7, described cylindrical shell 7 upper ends are provided with the convex edge 5 to outer lug, and the quantity of described convex edge 5 is at least two, and evenly distributes along the circumference of cylindrical shell 7.Being provided with on cylindrical shell 7 outer walls is few two convex tendons 6 that the position is relative.The inwall of cylindrical shell is provided with bracing frame 4, the screwed hole 8 of the center of bracing frame 4 for connecting is combined with screw rod 9 in the screwed hole 8, the upper end of screw rod 9 is provided with gland 2, be provided with sealing ring 1 with cylindrical shell 7 touching positions on the gland 2, the upper surface of described gland 2 is provided with a shrinkage pool 3.
As shown in Figure 2, shower nozzle 11 is installed on Fluid cutting-off valve body during use, handle 10 is housed on the shower nozzle 11, match with shrinkage pool 3 on the gland 2 in the lower end of handle 10, turning handle 10 during unlatching, and handle 10 drives gland 2 rotations simultaneously, and gland 2 upwards rises and just can spray at this moment.
