Abstract
The utility model provides a valve case structure, when it can guarantee valve seal betterly, satisfied high temperature resistance requirement, guaranteed the sealing performance of valve, it includes the case body, its characterized in that: and a cobalt-based alloy layer is arranged at the lower end of the valve core body.
Description
Technical Field
The utility model relates to a technical field that the valve industry was made, in particular to valve case structure.
Background
The valve usually realizes the function of opening and closing water flow by isolating the water inlet and the water outlet through the valve core, the temperature of fluid flowing in the valve is different, so the valve core on the valve ensures the sealing of the valve, the valve core is still suitable for the fluid with different temperatures, and the sealing element in the valve core can not necessarily meet the requirement of high temperature by adopting the common valve core.
Disclosure of Invention
To the technical problem, the utility model provides a valve core 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 core structure of valve, its includes the case body, its characterized in that: and a cobalt-based alloy layer is arranged at the lower end of the valve core body.
Further characterized in that the cobalt-based alloy layer is inclined; the cobalt-based alloy layer is formed by welding and surfacing through a welding electrode; the welding electrode grade is D802 alloy; the thickness of the cobalt-based alloy layer is not less than 3 mm; an annular groove is formed in the valve core body; the valve core body is provided with a balance hole; the valve core body is provided with a threaded connecting hole.
The utility model adopts the above structure, because case body lower extreme is provided with the cobalt-based alloy-layer, the sealed but high temperature resistance nature of valve not only can be guaranteed to the cobalt-based alloy-layer, has guaranteed that the valve can both guarantee the leakproofness of valve under the fluid of different temperatures.
Drawings
Fig. 1 is a schematic diagram of the valve core structure of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1, a valve core structure of a valve includes a valve core body 1, the valve core body 1 is provided with a threaded connection hole 2, the valve core body is connected with a driving mechanism through the threaded connection hole, a cobalt-based alloy layer 3 is arranged at the lower end of the valve core body 1, the cobalt-based alloy layer 3 is inclined, the inclination angle is 25-45 degrees, the cobalt-based alloy layer is formed by welding and overlaying welding a welding electrode grade D802 alloy, the thickness of the cobalt-based alloy layer is not less than 3mm, when the inclined valve core is matched with a valve seat, the sealing performance of the valve is ensured, the valve can be ensured by adopting the cobalt-based alloy layer, the sealing performance of the valve can also be ensured, and the sealing performance of the.
The valve core body 1 is provided with the annular groove 4, so that the stress area of high-pressure fluid is increased, and the stable operation of the valve core is ensured.
The valve core body 1 is provided with a balance hole 5, and the balance hole 5 is penetrated through the upper end and the lower end of the valve core to realize the pressure of the upper end and the lower end of the valve core
The balance of forces reduces the thrust of the actuator.
The present invention and the embodiments thereof have been described above schematically, and the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto, and those skilled in the art will be suggested by the teachings thereof, and without departing from the spirit of the present invention, without creatively designing the structural mode and the embodiments similar to the technical solution, all of which shall fall within the protection scope of the present invention.
