Abstract
The utility model relates to an angle type blowoff valve which comprises a handle component, a rack component and a valve body component, wherein a material charging box component is arranged between the rack component and the valve body component, a valve rod is arranged in the material charging box component, the top end of the valve rod is connected with the handle component through the rack component, and a valve rod sealing surface which is matched with a fluid inlet sealing surface of the valve body component is arranged at the bottom end of the valve rod, and the valve rod and the sealing surface of the valve rod are controlled by the support component and the handle component. A valve is closed by tightly pressing the sealing surface of the valve rod and the fluid inlet sealing surface of the valve body, and the valve is opened by separating the sealing surface of the valve rod and the fluid inlet sealing surface of the valve body component. The angle type blowoff valve is capable of effectively avoiding direct washing of high-speed fluid and residues. Meanwhile, nest grooves around the sealing surface of the valve body can product a eddy area which is higher than a pressure in the center of the fluid when the high-speed fluid flows through the periphery of the nest grooves so as to be beneficial to preventing the high-speed fluid from being close to the sealing surface of the valve body and further avoid the washing of the high-speed fluid and the residues on the sealing surface of the valve body.
Description
Technical field
The utility model relates to valve, refers in particular to the angie type blowdown valve that the industries such as a kind of suitable oil, chemical industry, thermoelectricity are used.
Background technique
Present blowdown valve, because valve rod is identical with sealing configuration and the stop valve of valve seat, when valve open, valve rod and seat portion form little gap, high-velocity fluid carries dregs, and the sealing surface of valve rod and valve seat is caused strong washing away, and also is like this when closing, cause sealing surface to be destroyed, shorten the working life of valve.
Summary of the invention
The purpose of this utility model is for the defective that exists in the background technique and problem improvement and bring new ideas in addition, and the angie type blowdown valve of a kind of novel structure, protection against erosion, long service life is provided.
The technical solution of the utility model is a kind of Handleset that comprises of structure, the blowdown valve of bracket component and valve component, the Stuffing box assembly wherein is set between bracket component and the valve component, in the Stuffing box assembly valve rod is set, valve stem tip is by bracket component connecting handle assembly, the bottom arranges the valve stem seal face that coincide with valve component fluid inlet sealing surface, and valve rod and valve stem seal face are by bracket component and Handleset control, valve stem seal face and valve component fluid inlet sealing surface compact throttle down, the valve stem seal face separates Open valve with valve component fluid inlet sealing surface.
Advantage of the present utility model and beneficial effect:
The effect of the utility model valve rod front end cylindricality throttling bodies, to make valve in opening procedure, two sealing surfaces that the valve body that valve is former when closing and valve rod combine, only have when they in relative separation behind the segment distance, be after the cylindricality throttling bodies breaks away from the fluid inlet passage of valve body fully, valve is only opening state, at this moment the sealing surface of valve rod is away from the outlet of valve body fluid inlet passage, and be positioned at passage place, large-section, the flow velocity of fluid is relatively low herein at this moment, the valve stem seal face is washed away greatly reduce.Otherwise the valve closing process too, and therefore valve rod front end cylindricality throttling bodies plays the effect that postpones to open or shift to an earlier date closing valve in this blowdown valve, avoids high-velocity fluid and slag to the high speed souring of valve stem seal face.Valve body sealing surface is because of relatively away from the high-velocity fluid channel outlet, effectively avoided directly washing away of high-velocity fluid and slag, simultaneously near the nest groove the valve body sealing surface at high-velocity fluid when flowing through near the nest groove, the vortex that generation is higher than the fluid center pressure, more be conducive to prevent the close valve body sealing surface of high-velocity fluid, further avoid high-velocity fluid and slag washing away valve body sealing surface.
