Description
Technical Field
The utility model relates to a technical field that the valve industry was made, in particular to valve structure.
Background
The valve usually realizes the function of opening and closing water flow by separating a water inlet and a water outlet through a valve core, the temperature of fluid flowing in the valve is different, so the valve seat and the valve core on the valve need to ensure the sealing of the valve, the valve seat and the valve core also need to adapt to the fluid with different temperatures, and by adopting a common valve structure, the sealing parts in the valve seat and the valve core can not necessarily meet the requirement of high temperature.
Disclosure of Invention
To the technical problem, the utility model provides a valve structure, when it can guarantee the valve seal betterly, satisfied high temperature resistance requirement, guaranteed the sealing performance of valve.
The technical scheme is as follows: the utility model provides a valve structure, its includes valve body and valve gap, set up water inlet and delivery port on the valve body, correspond on the valve body the water inlet with be provided with the case between the delivery port, the valve rod is connected to the case, correspond on the valve body the case is provided with disk seat, its characterized in that: and a valve seat cobalt-based alloy layer is arranged at the upper end of the inner hole of the valve seat, and a valve core cobalt-based alloy layer matched with the valve seat cobalt-based alloy layer is arranged on the valve core.
The valve seat cobalt-based alloy layer and the valve core cobalt-based alloy layer are both inclined; the valve seat cobalt-based alloy layer and the valve core cobalt-based alloy layer are formed by welding and surfacing welding through welding electrodes; the welding electrode is made of D802 alloy; the thicknesses of the valve seat cobalt-based alloy layer and the valve core cobalt-based alloy layer are not less than 3 mm; the valve core is provided with an annular groove; the valve core is provided with a balance hole; the valve core is provided with a threaded connecting hole; a packing pad is arranged between the valve rod and the valve cover; the filler pad is made of chromium material.
The above structure is adopted in the utility model, because valve seat body hole upper end is provided with disk seat cobalt base alloy-layer, be provided with on the case with disk seat cobalt base alloy-layer complex case cobalt base alloy-layer, disk seat cobalt base alloy-layer and the cooperation of case cobalt base alloy-layer not only can guarantee the sealed but also have high temperature resistance's of valve nature, still can both guarantee the leakproofness of valve under the fluid of different temperatures.
