Abstract
The utility model is related to a kind of new tap structure, including faucet body, cock axle and dovetail configuration, between the cock axle and faucet body using welding, be bonded and connect or connect by being bonded to connect to be welded with, the dovetail configuration includes the dovetail body in groove and insertion groove on faucet body.This structure substantially increases the functional reliability of cock under high pressure operating mode on the premise of lower cost, while also reducing processing technology difficulty, improves maintainability and yield rate.
Description
Technical field
The utility model is related to valve technology field, and in particular to a kind of Split type novel tap structure.
Background technology
Cock should meet performance requirement, technique is taken into account again as one important part of plug valve, its manufacture method
Property and cost.Existing technical scheme is：By cock integral casting forming, cock is then processed using the method for machining
Axle and dovetail configuration.Due to plug valve in the course of the work, the cock axle and dovetail configuration of cock will bear certain load work
With, common casting cock, because the mechanical property of casting material is relatively low, under high pressure operating mode, cock axle easily occurs curved
Also easily there is plastic deformation or heavy wear in song deformation, or even fracture, dovetail configuration, cock may be caused to act certain number of times
Afterwards plug valve cannot normal work, even result in security incident.On the other hand, for larger-size cock, monoblock cast
It is easily caused cock shaft end and defect occurs, product percent of pass is very low；And using solid forging or use high performance material casting instead
Cock then considerably increases manufacturing cost.
The content of the invention
For the deficiencies in the prior art, problem to be solved in the utility model is to provide a kind of functional reliability
Height, with low cost, the new tap structure of high yield rate.
The technical scheme that the utility model solves the above problems is：
A kind of new tap structure, including faucet body, cock axle and dovetail configuration, lead between the cock axle and faucet body
Cross and weld, be bonded and connect or connect by being bonded to connect to be welded with, the dovetail configuration is included in groove and insertion groove on faucet body
Dovetail body.Faucet body is the carrier of primary seal, and its intensity requirement is relatively low, using casting.Cock axle should be supported
Faucet body, axial force and moment of torsion needed for valve opening and closing is born again will also ensure to realize that the surface roughness of reliable sealing will
Ask, performance material higher need to be selected, formed by shape extrusion.Dovetail configuration due to being also subjected to larger load, from property high
Energy shape extrusion is formed.
Cock axle includes axle and cock lower axle in cock, and axle is welded with by pin connection with faucet body and connect or key in the cock
Connection is welded with and connects, and because cock lower bearing is loaded smaller, cock lower axle is with faucet body directly using welding.
Faucet body and dovetail configuration are connected by screw, can be by knockout screw after dovetail configuration is worn or damages
Dovetail configuration is changed, tap assembly is formed, so as to ensure the service behaviour requirement of cock.
The groove is dovetail groove or rectangular channel.
Faucet body and dovetail configuration, faucet body and cock axle are processed by different materials formed respectively.
Advantage of the present utility model：Using split type tap structure, can both ensure that the performance met when cock works makes
With requiring, and with relatively low manufacture processing cost.And split type component is in assembly and connection, connected mode reliability, cost
It is cheap, while reducing the processing technology difficulty of cock, improve the yield rate and maintenanceability of cock.
Brief description of the drawings
Fig. 1 is one structural representation of specific embodiment of the utility model.
Reference：1- dovetail configurations, 2- screws, 3- faucet bodies, axle in 4- cocks, 5- cock lower axles
Specific embodiment
Content of the present utility model is described in further detail below in conjunction with the drawings and specific embodiments：
As shown in figure 1, axle 4 and rotation in a kind of new tap structure, including dovetail configuration 1, screw 2, faucet body 3, cock
Plug lower axle 5, during fabrication processes axle in cock 4, cock lower axle 5, faucet body 3 and dovetail configuration 1 respectively.Dovetail configuration 1 is wrapped
Include the dovetail body in the groove and insertion groove on faucet body 3.Because faucet body 3 is the carrier of primary seal, its intensity requirement
It is relatively low, can typically use cast steel or ductile cast iron material.Axle 4 and cock lower axle 5 should support faucet body 3 in cock, and
Axial force and moment of torsion needed for bearing valve opening and closing, will also ensure to realize the surface roughness requirements of reliable sealing, need to select
Performance material higher, such as stainless steel；Dovetail configuration 1 is also adopted due to being also subjected to larger load from high-performance stainless steel
With processing, required with meeting performance, and process the screwed hole of screw, to be fastenedly connected with the later stage of faucet body 3.
By axle in cock 4 and faucet body 3 by first being connect with pin or be bonded, afterwards using carrying out reliable adding by the way of welding
Gu, due to cock lower axle 5, to bear load smaller, so cock lower axle 5 and faucet body 3 by the way of welding then directly using being connected
Connect, you can meet use requirement.
After the casting of faucet body 3, the thread mill drilling by the way of machining, with guarantee and dovetail configuration 1
Screwed hole coordinates, and faucet body 3 is assembled with dovetail configuration 1 afterwards, and be reliably connected using screw 2.By dovetail knot
The two ends of structure 1 are fixed with argon arc welding, it is ensured that connection fastening is reliable, while all screws 2 also need to be prevented with the mode of spot welding
Pine.
The groove is dovetail groove or rectangular channel.
A kind of technological method for processing of the new tap structure of plug valve, comprises the following steps：
(1) axle 4 and cock lower axle 5 are individually processed using bar section of stainless steel in cock；
(2) faucet body 3 uses Mechanical processing of casting, and processes the groove assembled with dovetail body；
(3) dovetail body is individually processed using bar section of stainless steel；
(4) axle 4 is connected by pin or key with faucet body 3 in cock, carries out reliable reinforcement by the way of welding afterwards；
(5) cock lower axle 5 is attached with faucet body 3 by the way of welding；
(6) be fastenedly connected for the two formation using screw after being assembled with dovetail configuration 1 by faucet body 3, finally with axle in cock
4th, cock lower axle 5 is assembled into tap assembly.
