Abstract
The invention discloses a valve with a ceramic protecting lip. The valve comprises a valve body and a valve core, wherein the valve body comprises a runner; an installing groove with the diameter being greater than that of the runner is formed in the runner along the axis; an annular ceramic protecting lip is arranged in the installing groove; the height of the protecting lip is equal to the width of the installing groove; the outer diameter of the protecting lip is less than the diameter of the installing groove; a heat inlaying material layer is arranged between the outer wall of the protecting lip and the installing groove; the inner diameter of the protecting lip is equal to the diameter of the runner; and the end surface of the protecting lip leans against the valve core when the valve core is in closed state. The invention aims at providing the valve with the ceramic protecting lip so as to improve the wear resistance of the inner wall of the metal valve and further prolong the service life of the metal valve.
Description
Technical field
The present invention relates to valve field, particularly relate to a kind of valve with pottery protection lip.
Background technique
Valve is the controlling component in fluid delivery system.Valve is for controlling the flowing of all kinds fluids such as air, 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 particle meeting wear valve valve body in fluid, shortens the working life of valve, therefore needs the wear resistance improving metal valve inwall to improve the life-span of metal valve.
Summary of the invention
The invention is intended to provide a kind of valve with pottery protection lip, improve metal valve working life to improve metal valve inwall wear resistance.
The valve of the band pottery protection lip in this programme; comprise valve body, spool; valve body comprises runner; runner has along axis the mounting groove that diameter is greater than Flow diameter, and be provided with the pottery protection lip of annular in mounting groove, the height of protection lip equals the width of mounting groove; the external diameter of protection lip is less than the diameter of mounting groove; be provided with hot inlaid material layer between the outer wall of protection lip and mounting groove, the internal diameter of protection lip equals the diameter of runner, and the end face of protection lip offsets with spool when being in closed condition.
The know-why of this programme and beneficial effect are: use metal valve when carrying the fluid containing major diameter solid particle, the wearing and tearing of particle to metal valve runner shorten the life-span of valve, increase the wear resistance of metal valve runner, just can extend the working life of metal valve, therefore in metal valve runner, be inlaid with the pottery protection lip be made up of engineering ceramic material, stupalith has good wear resistance, wear resistance is better than the metal being made generally in valve, fluid thus avoid fluid friction metal valve body and improve valve working life; Be fixed in runner to make protection lip; hot inlaid material layer is provided with between pottery protection lip outer wall and mounting groove; hot inlaid material layer is through heating and melting and after solidifying, pottery can be protected lip be fixed in mounting groove, prevents pottery protection lip play and damage pottery protection lip in runner.
Following scheme is the optimized project of such scheme:
Optimized project one: all circumference is uniform has some bar-shaped troughs for described mounting groove and described pottery protection lip outer wall, is filled with hot inlaid material, after heat is inlayed, prevents pottery protection lip from circumference rotation occurring in mounting groove in bar-shaped trough.
Optimized project two: described bar-shaped trough has barb groove, is filled with hot inlaid material in barb groove, after heat is inlayed, prevents pottery protection lip from mounting groove, axial rotation occurring.
Optimized project three: the quantity of described bar-shaped trough is 3-8, and quantity is less than 3, bad to the stopping effect of pottery protection lip; Quantity is greater than 8, reduces the intensity of pottery protection lip.
Optimized project four: the thickness of described hot inlaid material layer is 3-5mm, thickness, lower than 3mm, cannot ensure the soundness that heat is inlayed; Thickness is greater than 5mm, will the boundary dimension of valve body be made correspondingly to design larger, waste material.
Accompanying drawing explanation
Fig. 1 is the structural representation of the valve of embodiment of the present invention band pottery protection lip.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: 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.
Example belt pottery protects the valve of lip substantially as shown in Figure 1: comprise valve body 1, spool 2 and runner 3, runner 3 runs through in valve body 1, runner 3 has along axis the mounting groove 4 that diameter is greater than runner 3 diameter, the pottery protection lip 5 of annular is installed in mounting groove 4, mounting groove 4 has six bar-shaped troughs 6 with pottery protection lip 5 outer wall is all circumferential uniform, hot inlaid material is filled with in bar-shaped trough 6, bar-shaped trough 6 has barb groove 7, hot inlaid material is filled with in barb groove 7, the height of protection lip equals the width of mounting groove 4, the external diameter of protection lip is less than the diameter of mounting groove 4, between the protection outer wall of lip and mounting groove 4 by hot inlaid material melt solidify after be formed with hot inlaid material layer 8, the internal diameter of protection lip equals the diameter of runner 3, the end face of protection lip offsets with the spool 2 when being in closed condition.
When manufacturing valve, valve is put into hot pointing machine and heat, stop heating after hot inlaid material is melted, hot inlaid material solidifies the hot inlaid material layer 8 of rear formation, and pottery protects lip 5 to be embedded in securely in mounting groove 4 by hot inlaid material layer 8.
Use metal valve when carrying containing the fluid of major diameter solid particle, fluid and wear resistance are better ceramic protects lip 5 to contact, and avoids fluid friction metal valve body 1 runner 3 and reduces valve working life.
Above-described is only embodiments of the invention, 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 prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
