Abstract

In a valve arrangement (1), particularly in a venting valve for a diecasting mold, at least one of the bores (19, 21) for pistons (3, 17) communicating with the mold is provided with a bushing (20, 18) which forms the running surface of the piston. The wear resistance of the bushing is preferably higher than that of the base material of the body of the valve arrangement, and it is replaceable. The former property results in an extended lifetime of the arrangement, as the material and the surface properties of the bushing may be selected and adjusted according to the purpose. The latter property allows one to replace the running surface in the case of wear, in particular without involving an enlargement of the actual bore (7, 16) for the piston (3, 17).

Description of the invention (Deng Ming's Secret Techniques (please read the precautions on the back before filling out this page) This invention relates to the configuration of the valve for pressure pounds, especially in accordance with the preamble of the first scope of the patent application This type of valve configuration is known, such as European Patent Application No. EP A 0'936,009, which is incorporated herein by reference. The valve described therein is- Long life due to special ventilation because the control element, that is, a piston, is no longer in contact with hot metal. • Ordering 丨 However, in this embodiment, as is the case with conventional valves, the valve cylinder and the control piston The cylinder must still be occasionally disassembled for inspection. Finally, the entire valve body must be removed and returned to the producer. The overhaul resulted in enlarged holes and required new surface treatments and pond cylinders. Therefore, after this procedure, the user The enlarged piston must be held in a bracket. SUMMARY OF THE INVENTION An object of the present invention is to increase the life of such a valve. Another object of the present invention is to simplify overhaul. Use for a patent The configuration defined around item 1 can accomplish at least one of the mentioned purposes. The remaining patent applications define these preferred embodiments. Therefore, the valve configuration according to the present invention is characterized in that the piston is at The inner movement of the bushing embedded in the valve body. The bushing is made of a material that is more wear-resistant than the surrounding valve 'and / or the running surface provided is at least partly a particularly wear-resistant surface, especially Exposed area. This surface can be made by itself in a variety of ways known to those skilled in the art 579311 A7 B7 V. Description of the invention (2 methods, for example, different nitriding methods, hard Physical vapor deposition of layers to obtain a schematic overview of the present invention will be further explained by reference to the illustrated embodiment. Figure 1 shows the cross section of the valve; Figure 2 shows the cross section of the second valve; Figure 3 is A cross section of a liner for a valve cylinder, and FIG. 4 is a cross section of a liner for a control piston in a second type of valve. DETAILED DESCRIPTION OF THE INVENTION The first figure is shown and explained in European Patent Application No. Ep_a-0,936,009. Valve phase The main function is the venting piston 3, which can be guided and displaced in the hole 7. At its back end, the venting piston 3 is equipped with a twist to a rod 9 actuated by a pneumatic element (control piston 11). Therefore, the actuation and deactivation of the pneumatic element η can cause the piston 3 to be removed and the opening 13 can be opened or closed. In the case of opening, the opening 3 will communicate with the second connection 15. For example, the opening 13 can be connected to the vent of the die-casting mold, while connection 15 can be used as an outlet. Compared to the valve according to European Patent No. E? -A-0,936,009, Figure 2 shows the more traditional structure of this valve, of which The piston 3 is actuated by a control piston 17 instead of a pneumatic element. The control piston 17 communicates with the mold cavity, and is thus exposed to a stress similar to that of the ventilation piston 3. Especially in the high-frequency die-casting operation of the casting process, it requires very high stresses (such as a temperature of 700 ° C, a flow rate of 100 m / s, and a pressure of 850 bar). In addition, the valve will be in direct contact with liquid metal, especially this paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) ----------------- ------ install ------- order ........ line · (Please read first Note on the back, please fill out this page again) 579311 A7 ___B7_ V. Description of the invention (3) Pistons 3 and 17. The pistons 3, 17 and the breathing port 16 of the bores 7 are thus exposed with very severe wear. If applicable, the piston 3 and the control piston π can be replaced quite easily in their place. According to the present invention, the bushing 20 is embedded in the hole 19 of the wide body 1 according to the embodiment of the present invention, as shown in FIG. The bushing 20 is fixed in the hole by a screw 14 and is made of a material that is particularly wear-resistant and suitable for use in this application. It can also be replaced where it is, thus providing the advantages of longer life and quick disassembly. Moreover, an extra large piston is no longer needed, whereby the user can very easily simplify the storage of the replacement piston 3. Similarly, in the embodiment according to FIG. 2, the hole 21 for controlling the piston 17 in the valve body has a lining 18 fixed to the hole 21 with a corresponding screw 23. 3 and 4 show enlarged views Illustrated bushes 20 and 18. Similarly, the following discussion can also be applied to the liner 18 of the control piston 17. A valve seat 24 is formed at a front end 22 of the bushing 20. The bushing 20 includes at least an outlet opening 25 and a hole 26 for receiving a fixing screw. In bushing 18, holes 28 are used for this purpose. The bushings 18, 20 are composed of appropriately selected materials. More suitable materials are high-strength steels suitable for subsequent processing, in particular (specified according to German industrial standards, the content here and after are expressed in weight percentages): X38 CrMoV 5 1 (average Value: 0.36 carbon, 1.1 silicon, 5.0 chromium, 1.1 key, 0.4 hunger), hardened and disc nitride; χ40 CrMoV 5 1 (average value: 0.4 carbon, 1.0 silicon, 5.2 chromium, 1.3.
