Description
Technical field
The present invention relates to valve field more particularly to a kind of valves of band ceramics protection lip.
Background technology
Valve is the control unit in fluid delivery system.Valve is used to that empty gas and water, steam, various corrosivity to be controlled to be situated between
The flowing of the various types fluid such as matter, mud, oil product, liquid metal and radiating medium.
Common valve is mostly metal manufacture in industry, when the fluid in valve includes larger diameter solid particle, stream
The metal inner surface of internal particle meeting wear valve valve body shortens the service life of valve, it is therefore desirable to improve metal valve
The wearability of inner wall is to improve the service life of metal valve.
Invention content
The invention is intended to provide a kind of valve of band ceramics protection lip, gold is improved to improve metal valve inner wall wearability
Belong to valve service life.
The valve of band ceramics protection lip in this programme, including valve body, spool, valve body includes runner, runner upper edge axis
The mounting groove that diameter is more than flow diameter is provided with, the ceramics protection lip of annular in mounting groove is installed, the height of lip is protected to be equal to
The width of mounting groove protects the outer diameter of lip to be less than the diameter of mounting groove, protects embedding equipped with hot insert between the outer wall of lip and mounting groove
Material layer, protects the internal diameter of lip to be equal to the diameter of runner, and spool when protecting the end face of lip with being closed offsets.
It the technical principle of this programme and has the beneficial effect that：Using metal valve in stream of the conveying containing major diameter solid particle
During body, particle shortens the abrasion of metal valve runner the service life of valve, increases the wearability of metal valve runner, with regard to that can prolong
The service life of long metal valve, therefore the ceramics protection made of engineering ceramic material is inlaid in metal valve runner
Lip, ceramic material have good wearability, and wearability is better than being made generally in the metal of valve, and fluid is so as to avoid fluid friction
Metal valve body and improve valve service life；In order to which protection lip is made to be fixed in runner, in ceramics protection lip outer wall and mounting groove
Between be equipped with the embedding material layer of hot insert, the embedding material layer of hot insert after heating and melting and solidification, can by ceramics protection lip be fixed on peace
In tankage, prevent ceramics protection lip in runner play and damage ceramics protection lip.
Following scheme is the prioritization scheme of said program：
Prioritization scheme one：The mounting groove and the ceramics protection lip outer wall are circumferentially uniformly provided with several bar-shaped troughs, item
Filled with hot inlaid material in shape slot, after hot insert is embedding, prevent ceramics protection lip from being circumferentially rotated in mounting groove.
Prioritization scheme two：Barb slot is provided on the bar-shaped trough, hot inlaid material is filled in barb slot, after hot insert is embedding,
Prevent ceramics protection lip from axial rotation occurring in mounting groove.
Prioritization scheme three：The quantity of the bar-shaped trough is 3-8, and quantity is less than 3, to the stopping effect of ceramics protection lip
It is bad；Quantity is more than 8, reduces the intensity of ceramics protection lip.
Prioritization scheme four：The thickness of the embedding material layer of hot insert is 3-5mm, and thickness is less than 3mm, can not ensure that hot insert is embedding
Fastness；Thickness is more than 5mm, and the appearance and size for making valve body is correspondingly designed bigger, waste of materials.
Description of the drawings
Fig. 1 is the structure diagram for the valve that band of embodiment of the present invention ceramics protect lip.
Specific embodiment
Below by specific embodiment, the present invention is described in further detail：
Reference numeral in Figure of description includes：Valve body 1, spool 2, runner 3, mounting groove 4, ceramics protection lip 5, bar shaped
The embedding material layer 8 of slot 6, barb slot 7, hot insert.
The valve of embodiment band ceramics protection lip is substantially as shown in Figure 1：Including valve body 1, spool 2 and runner 3, runner 3
It runs through in valve body 1,3 upper edge axis of runner is provided with the mounting groove 4 that diameter is more than 3 diameter of runner, and annular is equipped in mounting groove 4
Ceramics protection lip 5, mounting groove 4 and ceramics protection 5 outer wall of lip are circumferentially uniformly opened there are six bar-shaped trough 6, are filled in bar-shaped trough 6
There is hot inlaid material, barb slot 7 is provided on bar-shaped trough 6, hot inlaid material is filled in barb slot 7, the height of lip is protected to be equal to
The width of mounting groove 4 is protected the outer diameter of lip to be less than the diameter of mounting groove 4, is protected embedding by hot insert between the outer wall of lip and mounting groove 4
Be formed with the embedding material layer 8 of hot insert after material melts solidification, the internal diameter of lip protected to be equal to the diameter of runner 3, protect the end face of lip with
Spool 2 when being closed offsets.
When manufacturing valve, valve is put into hot pointing machine and is heated, stop heating after making the embedding material melts of hot insert, hot insert is embedding
The embedding material layer 8 of hot insert is formed after material solidification, ceramics protection lip 5 is embedded in mounting groove 4 by the embedding material layer 8 of hot insert securely.
Using metal valve when conveying the fluid containing major diameter solid particle, fluid with wearability preferably protect by ceramics
Lip care 5 contacts, and avoids 1 runner 3 of fluid friction metal valve body and reduces valve service life.
Above-described is only the embodiment of the present invention, and the common sense such as well known concrete structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these should also be considered as protection scope of the present invention, these all do not interfere with what the present invention was implemented
Effect and practical applicability.The scope of protection required by this application should be based on the content of the claims, in specification
The records such as specific embodiment can be used for explaining the content of claim.
