Abstract
The utility model provides a combined structure's water conservancy diversion awl for pressure regulating valve, this water conservancy diversion awl includes the awl shell, and this awl shell main aspects is through overhauing flange and base member sealing connection, overhauls the hole clearance fit back sealing connection of end cover through tang and maintenance flange. The utility model discloses can satisfy the pressure regulating valve water conservancy diversion usefulness after lightening through optimizing, and make simply, simple to operate, save with the material, investment cost is low to make the cone light durable, and overhaul in the valve of being convenient for.
Description
Technical Field
The utility model belongs to the technical field of mechanical valve makes, concretely relates to can satisfy integrated configuration that pressure regulating valve water conservancy diversion was used.
Background
The design principle of mechanical products is to ensure the necessary functions of the products and meet the requirements of customers on the functions and services of the products, so that the manufacturing cost is the lowest. The design of the product not only comprises a pattern design, but also comprises a process design and a production design, the function or the shape of the part is simplified as much as possible, the blank process and the processing process are more effectively combined, and the process technology which saves resources and reduces pollution is adopted as much as possible.
The guide cone of the existing pressure regulating valve is of an integral casting structure, is thick and heavy, brings difficulty to installation and disassembly, and needs to be completely disassembled when the valve is overhauled, so that the operation is time-consuming and labor-consuming and is uneconomical.
SUMMERY OF THE UTILITY MODEL
The utility model provides a composite construction's diversion awl for pressure regulating valve replaces current whole cast diversion awl, is guaranteeing under the condition of part intensity, and the weight of diversion awl reduces by a wide margin.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a combined structure's water conservancy diversion awl for pressure regulating valve, this water conservancy diversion awl includes the awl shell, and this awl shell main aspects is through overhauing flange and base member sealing connection, overhauls the hole clearance fit back sealing connection of end cover through tang and maintenance flange.
The conical shell is provided with a plurality of pressure balancing holes.
The maintenance end cover is provided with a reinforcing rib, and the reinforcing rib is provided with a hoisting hole.
The utility model discloses regard as basic design principle with the thinking that adopts resources are saved, pollution abatement as far as possible, with current whole casting water conservancy diversion awl through reasonable decomposition, make it become assembly, equipment, dismantle the simplest structure in the technology to under the condition of guaranteeing part strength, the weight of water conservancy diversion awl reduces by a wide margin, the utility model discloses change the steel casting into plate and assembly and welding spare, solved the environmental pollution problem that the casting trade is hardly thoroughly solved and the problem of casting defect appears easily in the product. Compare in current whole casting formula water conservancy diversion awl thick heavy, the assembly, dismantle the inconvenience of overhauing in difficulty and the valve, the utility model discloses make simply, the installation is simple and convenient, saves with the material, and the environmental protection, investment cost is low, and the cone is light durable to the valve in of being convenient for overhauls.
Drawings
FIG. 1 is a schematic structural view of the present invention;
figure 2 is a schematic view of the positioning between the service end cap and the service flange.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1 and 2, the flow guide cone for the pressure regulating valve with the combined structure comprises a cone shell 7, wherein the large end of the cone shell 7 is hermetically connected with a base body 1 through an overhauling flange 2, and an overhauling end cover 5 is hermetically connected with an inner hole 2-1 of the overhauling flange 2 through a spigot 5-1 in a clearance fit mode.
The maintenance flange 2 is a part made of plates and provided with bolt holes, the maintenance end cover 5 is a plate weldment and provided with bolt holes, the maintenance flange 2 and the maintenance end cover 5 are connected through bolts 3, then the maintenance flange 2 and the maintenance end cover 5 are connected together with the conical shell 7 through the bolt holes in the maintenance flange, the maintenance end cover 5 and the maintenance flange 2 are connected, the maintenance flange 2 and the base body 1 are connected, and the sealing element 4 is used for sealing.
The conical shell 7 is provided with a plurality of pressure balancing holes 7-1. The central line of the cone shell 7 is coincided with the axis of the pressure regulating valve and is a parabolic cone formed by welding steel plates. Compared with the existing integral casting type flow guiding cone structure, the cone shell 7 for flow guiding not only has the advantages of reducing energy consumption and improving the operating efficiency of the pressure regulating valve, but also effectively improves the airflow flow state of the pressure regulating valve, airflow can smoothly enter the valve from a pressure balance hole 7-1 arranged on the cone shell 7 along a regular conical slope surface, and the internal and external pressures of the flow guiding cone shell 7 are balanced, so that the thin-wall cone shell 7 is prevented from deforming to influence the flow guiding curve of the pressure regulating valve due to overlarge internal and external pressure difference. Thereby enabling the flow cross section to shrink uniformly along the airflow direction, increasing the air inlet flow speed uniformly, eliminating airflow disorder and reducing pressure loss. The big end of the conical shell 7 is a cylindrical shell with a flange, and a pressure balance hole 7-1 is formed in the cylindrical shell.
The maintenance end cover 5 is provided with a reinforcing rib 6, and the reinforcing rib 6 is provided with a hoisting hole. Has the function of a hanging ring and is convenient to lift and install.
