Abstract
The utility model discloses a valve with a loose joint, and the valve comprises a valve body and a valve core which is arranged in the valve body, wherein the valve core is controlled by a control handle through a valve rod; the valve body is formed by plastic via injection moulding; one end of the valve body is connected with a metal pipe via injection moulding; the loose joint is sheathed at the periphery of the pipe body of the metal pipe; and meanwhile, an outward flange is arranged at the end of the metal pipe. According to the utility model, during the injection moulding of the valve body, the metal pipe which is sheathed by the loose joint at the periphery is directly connected with one end of the valve body via injection moulding, so that the valve body which is made of plastic can conveniently and directly have a loose joint structure.
Description
Technical field
The utility model relates to a kind of valve, specifically with the valve of loose joint.
Background technique
Valve is the controlling component in the fluid delivery system, have by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.The pipeline that connects for its both sides of valve at present generally connects through nut or the threaded pipe of being located at the end, and nut is fixed on valve one end end and also is movably connected in valve one end end.The valve body material of existing valve mostly for metallic material its through metal tube be threaded valve one end end and socket nut, realize that the movable screw cap is convenient to connect.The valve of said structure, metal tube, nut are metallic material, technological deficiencies such as Heavy Weight, price height, connection complicacy.The existing valve that also has some valves, connecting tube to adopt the plastic materials one to make; Though but this kind valve is easy to connect, price is low, easy to connect can't to bear bigger pipeline pressure damaged easily; Also can't realize simultaneously the loose joint structure of nut fully, have the restriction of bigger structural imperfection and application area.How to realize a kind ofly having the loose joint nut simultaneously, valve easily manufactured, in light weight, safe in utilization is the technical problem that those skilled in the art need overcome.
China's utility model patent patent No. 02232006.7 discloses a kind of loose joint valve; Be to comprise that the wherein end internal thread screw thread structure that valve body is connected with pipeline changes system into the external thread wire buckle structure of forming loose joint with locknut and joint; Valve is become one with loose joint; Save raw material thereby make, quick for installation, reduce connection pipe fitting and sealing joint material.This technology does not propose how to reduce the technical clarification that has loose joint nut structure this respect under weight, the assurance bearing capacity.
Summary of the invention
The utility model provides a kind of valve of easily manufactured, safe in utilization, lightweight band loose joint.
A kind of valve with loose joint; Comprise valve body and be located at the spool in the valve body, spool is controlled by Joystick through valve rod, and described valve body is the plastics integrated injection molding; Valve body one end injection moulding is connected with metal tube, and metal tube body periphery is with loose joint and is provided with outward flanging in the metal tube end simultaneously.This kind is employed in valve body one end that plastics make through direct injection molding way, and the metal tube that when the injection moulding valve body, periphery is with loose joint directly is connected with valve body one end injection moulding, and the valve body of realization plastic materials can make things convenient for, directly have the loose joint structure.
The plastic raw material of described valve body is the PP-R material, because characteristics such as the PP-R material weight is light, corrosion-resistant, non-scaling, long service life are highly suitable for the valve body manufacturing.
Described valve body one end injection moulding is connected with metal tube, and the other end is for coaxial with valve body or be the straight length that angle is provided with each other; Described and valve body is the straight length that angle is provided with each other, and its angle is 45 degree or 60 degree or 90 degree, and the setting of this kind angle also can be provided with according to actual needs conveniently and connect.
Described metal tube is provided with through hole on injection moulding connecting end tube wall; Be injected with the plastic materials of valve body one in the through hole; The join strength that strengthens metal tube and plastics valve body has kept the turbidity test of inner wall of metal tube, and the metal tube changes in flow rate of avoiding simultaneously adopting other Placements to cause is a kind of Placement of novel original creation.
The utility model directly is connected with valve body one end injection moulding through the metal tube that periphery is with loose joint when the injection moulding valve body, realizes that the valve body of plastic materials can make things convenient for, directly have the loose joint structure.
Description of drawings
Fig. 1 is the valve mechanism schematic representation of the utility model band loose joint.
Embodiment
Referring to accompanying drawing 1, a kind of valve with loose joint of the utility model comprises valve body 4 and is located at the spool 3 in the valve body 4 that spool 3 is controlled by Joystick 2 through valve rod 1, the switch of Joystick 2 control spools 3.Valve body 4 is the plastics integrated injection molding, and valve body 4 one end injection mouldings are connected with metal tube 5, and metal tube 5 body peripheries are with loose joint 6 and are provided with outward flanging in metal tube 5 ends simultaneously.The valve body of realizing plastic materials can make things convenient for, directly have the loose joint structure, makes valve convenient the connection, have the characteristics of low weight, high safety in utilization.
Plastic raw material as structure optimization valve body 4 is the PP-R material.Valve body 4 one end injection mouldings are connected with metal tube 5, and the other end is for coaxial with valve body 4 or be the straight length that angle is provided with each other; Described and valve body 4 is the straight length that angle is provided with each other, and its angle is 45 degree or 60 degree or 90 degree, makes things convenient for other pipelines of valve body connection, avoids producing unnecessary link.
