Abstract
The application discloses a valve of area pottery protection lip, which comprises the following components: a valve body, and a valve cor, the valve body contains the runner, it has the diameter to be greater than the mounting groove of runner diameter to open along the axis on the runner, install annular pottery protection lip in the mounting groove, the width that highly equals the mounting groove of protection lip, the external diameter of protection lip is less than the diameter of mounting groove, it inlays the material layer to be equipped with heat between outer wall and the mounting groove of protection lip, the internal diameter of protection lip equals the diameter of runner, the terminal surface and the case when the closed condition of protection lip offset. This patent is anticipated is providing a valve of area pottery protection lip to improve metal valve inner wall wearability and improve metal valve life.
Description
Technical field
This utility model relates to valve field, particularly relates to a kind of valve protecting lip with pottery.
Background technology
Valve is the control parts in fluid delivery system. Valve is for controlling the flowing of all kinds fluids such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Valve conventional in industry mostly is metal manufacture; when the fluid in valve comprises larger diameter solid particle; the metal inner surface of the granule meeting wear valve valve body in fluid, shortens the service life of valve, it is therefore desirable to improve the wearability of metal valve inwall to improve the life-span of metal valve.
Utility model content
This utility model is intended to provide a kind of valve protecting lip with pottery, improves metal valve service life to improve metal valve inwall wearability.
The valve protecting lip with pottery in this programme; including valve body, spool; valve body comprises runner; having the diameter mounting groove more than flow diameter along axis on runner, be provided with the pottery protection lip of annular in mounting groove, the height of protection lip is equal to the width of mounting groove; the external diameter of protection lip is less than the diameter of mounting groove; being provided with hot inlaid material layer between outer wall and the mounting groove of protection lip, the internal diameter of protection lip is equal to the diameter of runner, and the end face of protection lip offsets with spool when being closed.
The know-why of this programme and having the beneficial effect that uses metal valve when the conveying fluid containing major diameter solid particle, the abrasion of metal valve runner is shortened the life-span of valve by granule, increase the wearability of metal valve runner, just can extend the service life of metal valve, therefore in metal valve runner, it is inlaid with the pottery protection lip being made up of engineering ceramic material, ceramic material has good wearability, wearability is better than being made generally in the metal of valve, and fluid is thus avoiding fluid friction metal valve body and improving valve service life; In order to make protection lip be fixed in runner; protect at pottery and be provided with hot inlaid material layer between lip outer wall and mounting groove; hot inlaid material layer through heating and melting and solidify after, pottery can be protected lip be fixed in mounting groove, it is prevented that pottery protection lip in runner play and damage pottery protection lip.
Below scheme is the prioritization scheme of such scheme:
Prioritization scheme one: described mounting groove and described pottery protection lip outer wall is all circumferential uniform has some bar-shaped troughs, is filled with hot inlaid material, after heat is inlayed, it is prevented that pottery protection lip circumferentially rotates in mounting groove in bar-shaped trough.
Prioritization scheme two: have barb groove on described bar-shaped trough, is filled with hot inlaid material, after heat is inlayed in barb groove, it is prevented that axial rotation occurs pottery protection lip in mounting groove.
Prioritization scheme three: the quantity of described bar-shaped trough is 3-8, quantity is less than 3, and the stopping effect that pottery is protected lip is bad; Quantity, more than 8, reduces the intensity of pottery protection lip.
Prioritization scheme four: the thickness of described hot inlaid material layer is 3-5mm, and thickness is lower than 3mm, it is impossible to ensure the fastness that heat is inlayed; The overall dimensions making valve body, more than 5mm, is correspondingly designed to bigger, wastes material by thickness.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model embodiment protects the valve of lip with pottery.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: valve body 1, spool 2, runner 3, mounting groove 4, pottery protection lip 5, bar-shaped trough 6, barb groove 7, hot inlaid material layer 8.
Embodiment with pottery protect lip valve substantially as shown in Figure 1: include valve body 1, spool 2 and runner 3, runner 3 runs through in valve body 1, runner 3 has the diameter mounting groove 4 more than runner 3 diameter along axis, the pottery protection lip 5 of annular is installed in mounting groove 4, mounting groove 4 and pottery protection lip 5 outer wall is all circumferential uniform has six bar-shaped troughs 6, hot inlaid material it is filled with in bar-shaped trough 6, bar-shaped trough 6 has barb groove 7, hot inlaid material it is filled with in barb groove 7, the height of protection lip is equal to the width of mounting groove 4, the external diameter of protection lip is less than the diameter of mounting groove 4, it is formed with hot inlaid material layer 8 after being melted solidification by hot inlaid material between outer wall and the mounting groove 4 of protection lip, the internal diameter of protection lip is equal to the diameter of runner 3, the end face of protection lip offsets with the spool 2 when being closed.
When manufacturing valve, being put into by valve in hot pointing machine and heat, make hot inlaid material stop heating after melting, form hot inlaid material layer 8 after the solidification of hot inlaid material, pottery is protected lip 5 to be embedded in securely in mounting groove 4 by hot inlaid material layer 8.
Using metal valve when conveying is containing the fluid of major diameter solid particle, fluid protects lip 5 to contact with wearability better pottery, it is to avoid fluid friction metal valve body 1 runner 3 and reduce valve service life.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this. Should be understood that; for a person skilled in the art, under the premise without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented. The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
