The valve solves the technical problems of poor sealing effect, bad connecting effect between a plastic pipe and the valve and the like of the existing valve. The valve comprises a valve body made of metal materials, a water service pipe arranged at the end part of the valve body and a connecting pipe which is made of plastics, arranged at the position of the water service pipe and is directly and fixedly connected with the water service pipe by a method of injection molding. The valve is has advantages that the end part of the water service pipe of the valve body has good leak tightness, the structure is simple, and the connecting pipe is firmly connected with water service pipe, etc.
Description
Technical field
The invention belongs to valve technology field, relate to a kind of valve.
Background technique
General valve comprises valve body, valve rod, handle, spool, and valve rod one end is connected with spool, and the other end passes valve body and is connected with handle.When existing various metal valve is connected with plastic pipe, when being connected with plastic pipe, connect with flange usually at the two ends of valve body.It is complicated to connect working procedure with flange, and the joint sealing can't guarantee, required workpiece kind and quantity is many, construction and the leak test time is grown, the processing cost of single joint is high.
For this reason, the Chinese patent notice of authorization has improved above-mentioned deficiency number for CN2750159Y discloses " plastic pipe that a kind of conveyance fluid is used and the link of metal valve ".Interior or the outer wall of plastic pipe has been pressed into the steel lining, and plastic pipe closely is connected with metal valve, and the steel lining is positioned at metal valve or outer.The utility model is pressed into the interior or outer wall of plastic pipe with the steel lining with the mode that directly is pressed into, and the length that plastic pipe and metal valve closely are connected formed sealing surface length when directly connecting with flange is long, so sealing effect is better.Connect the plastic pipe that is pressed into the steel lining on this valve body, behind fit sealing, can directly weld with the special plastic welding machine, no longer need be with links such as flanges.
But also there is deficiency in the solution that this patent provides: at first, plastic pipe and metal valve tight is connected to make and adopts the mode that is pressed into, and connects insecurely, and plastic tube breaks away from valve easily and perhaps can rotate with valve.Secondly, connect through fastening sheet, because fastening sheet will snap between valve and the plastic tube, than higher, it is bad plastic tube of return loss that too big words snap in to the production requirement of fastening sheet, and too little words can't play fastening effect.And the fastening seal action that plays simultaneously will not reach sealing effect if fastening sheet is off quality.
Summary of the invention
The objective of the invention is to existing above-mentioned problem, a kind of valve that is connected close and firm of a kind of simple in structure, good sealing effect, plastic tube and valve is provided.
The object of the invention can be realized through following technical proposal: a kind of valve; Comprise the valve body of processing by metallic material; The end of described valve body has water service pipe; It is characterized in that described water service pipe place is provided with the adapter that is made of plastics, said adapter be through injection moulding method directly and water service pipe be connected.
The two ends of the water service pipe of this valve connect goes up adapter that plastics process being connected with convenient and other plastic pipe.The end of valve body is put in the mould, and with being melt into liquid plastic pouring in mould, the adapter that the cooling back forms directly is fixed on the end of water service pipe.Directly adapter is connected in the end of water service pipe through the method for injection moulding, simple in structure, and the good airproof performance that connects.
In above-mentioned valve, be provided with the axial limiting structure that strengthens both axial connectivity robustness between described water service pipe and the adapter.Strengthen being connected of water service pipe and adapter through the axial limiting structure.
In above-mentioned valve, described axial limiting structure comprises in several grooves one that are arranged on the outer circumferential face of water service pipe end and the tube wall that is arranged on adapter and above-mentioned groove one corresponding convex body one that described convex body one is embedded in the above-mentioned groove one.Convex body one is embedded in and makes water service pipe form the axial limiting structure with taking in the groove one.In addition, it also is feasible the position of groove one and convex body one being exchanged.
In above-mentioned valve, be provided with the circumferential limit structure that strengthens both circumferential connectivity robustness between described water service pipe and the adapter.Strengthen being connected of water service pipe and adapter through circumferential limit structure.
In above-mentioned valve, described circumferential limit structure comprise on the end face that is arranged on the water service pipe end several breach be arranged in the tube wall of adapter and the corresponding projection of above-mentioned breach, described projection is embedded in the above-mentioned breach.Projection is embedded in and makes water service pipe form circumferential limit structure with taking in the breach.In addition, it also is feasible the position of breach and projection being exchanged.
In above-mentioned valve, described water service pipe end inner peripheral surface is provided with several grooves two, in the tube wall of taking over, is provided with the convex body two corresponding with above-mentioned groove two, and described convex body two is embedded in the above-mentioned groove two.Further strengthen axial limiting through groove two and convex body two.
In above-mentioned valve, described groove one is annular with groove two.The structure of annular is easy to processing.
In above-mentioned valve, described breach evenly distributes on the end face of water service pipe end.This structure can make the adapter that is connected the water service pipe end stressed evenly.
In above-mentioned valve, described valve body comprise main valve body and with the auxiliary valve body of main valve body through scyewed joint, on the end of described main valve body and auxiliary valve body, be fixed with adapter respectively.Because main valve body is connected through screw thread with auxiliary valve body, assemble again after therefore can be earlier the method for adapter through injection moulding being fixed on the end of main valve body and auxiliary valve body.Adopt such manufacturing process, can avoid adapter when valve body one end to occur can not having influence on the adapter of the other end when defective, thereby improve the up-to-standard rate of product, avoid waste.
Compared with prior art, this valve has following advantage:
1, will take over directly through the method for injection moulding in the end of the water service pipe of this valve body and be connected, good airproof performance simultaneously, has saved parts such as use seal ring, nut, simplifies the structure.
2, be provided with axial limiting structure and circumferential limit structure in the end of adapter and water service pipe, increase the join strength of adapter and water service pipe, soundness is high.
