Abstract
The utility model discloses a hand-switching valve which comprises a valve body, a rotating valve core, a through hole and a sealing sleeve, wherein an incoming flow channel and an outgoing flow channel are arranged at the two ends of a valve cavity of the valve body; the rotating valve core is arranged in the middle of the valve cavity and is made of a hard material; the through hole which allows fluid to flow through is arranged on the rotating valve core; and the sealing sleeve is made of polytetrafluoroethylene and is leaned against the lower surface of the rotating valve core. When the rotating valve core rotates to the through hole and is in butt joint with the sealing sleeve, the incoming flow channel and the outgoing flow channel are communicated, and the valve is opened; and when the rotating valve core rotates to the through hole and is staggered with the sealing sleeve, the incoming flow channel and the outgoing flow channel are closed. The hand-switching valve also comprises a driving handle which drives the rotating valve core to rotate through a rotating shaft. The high efficiency production of the hand-switching valve is realized under the condition of ensuring the sealing quality through the rotating valve core made of the hard material and the sealing sleeve made of the polytetrafluoroethylene.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of hand rotary valve.
Background technique
The hand rotary valve is a kind of widely used valve part at present; Be through the via that fixed spool and rotational valve core had that is provided with in the valve body under the driving of handle with sleeve relatively or interlace the conducting that realizes valve with close, fixed spool uses the stupalith of hard to process usually.The shortcoming of this structure is: fixed spool and rotational valve core faying surface each other paste hard being connected for hard, and for satisfying the high machining accuracy of seal request needs, so production efficiency of products receives very big influence.
The model utility content
The utility model is in order to overcome defective in the above-mentioned existing technology, to substitute ceramic fixed spool, when guaranteeing sealability, can realize the High-efficient Production of hand rotary valve through the stuffing box gland processed by the soft material of teflon.
For realizing above-mentioned purpose, the utility model provides a kind of hand rotary valve, it is characterized in that, comprising: valve body, and its valve pocket two ends are provided with the turnover runner; Rotational valve core, it is located at the valve pocket middle part and is processed by hard material, and rotational valve core is provided with the via hole that allows fluid to pass; Stuffing box gland, it is processed by teflon, and the stuffing box gland sealing is connected to the lower surface of rotational valve core.When said rotational valve core turns to said via hole when docking with stuffing box gland, the turnover runner is communicated with valve opening; When rotational valve core turns to said via hole and stuffing box gland when staggering, the sealing of turnover runner.
Wherein, this hand rotary valve also comprises driving handle, and driving handle drives rotational valve core through rotating shaft and rotates.
Wherein, butt has spring between driving handle and the rotational valve core, and spring housing is connected on rotating shaft, and spring is used to keep the butt pressure between rotational valve core and the stuffing box gland.
Wherein, the outer of stuffing box gland is provided with protruding flange of ring week, and the lower surface of flange is socketed with seal ring, and seal ring is by the inboard port clamping of flange with the turnover runner.
Wherein, rotational valve core is processed by aluminum alloy material die casting, and the lower surface of the rotational valve core that connects with stuffing box gland has sealed precision.
Compared with prior art, rotational valve core that the utility model is processed through hard material and the stuffing box gland processed by the soft material of teflon are realized the High-efficient Production of hand rotary valve under the prerequisite that guarantees airtight quality to substitute ceramic fixed spool.
Description of drawings
Fig. 1 is the main sectional view of the utility model hand rotary valve.
The 1-valve body, 11-runner, 2-handle, 3-stuffing box gland, 31-flange, 4-rotational valve core, 5-spring, 6-seal ring.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
The structure of the hand rotary valve of the utility model is as shown in Figure 1, comprises valve body 1 and driving handle 2, and wherein valve body 1 has the cavity of ccontaining control valve open and close device, and the two ends of cavity are connected with turnover runner 11 respectively.The stuffing box gland 3 that the control gear of valve open and close is processed by the rotational valve core 4 and the soft teflon of hard constitutes; Stuffing box gland 3 is embedded in the joint of valve body cavity and runner; Pass through the sealing butt that spring 5 keeps certain pressures between the sealing surface of hard rotational valve core 4 and stuffing box gland 3 ports; Rotational valve core 4 is provided with the via hole that allows fluid to pass, and handle 2 drives rotational valve core 4 through rotating shaft and rotates valve opening when the fluid via hole of rotational valve core 4 docks with stuffing box gland 3; When the fluid via hole of rotational valve core and stuffing box gland 3 staggered, the bottom surface of rotational valve core 4 and stuffing box gland butt sealed runner.
Further as shown in Figure 1, the outer of stuffing box gland 3 has protruding flange 31 of ring week, and the lower surface of flange 31 is socketed with seal ring 6, and seal ring 6 receives stuffing box gland flange 31 and runner to get into port (promptly passing in and out the inboard port of the runner) clamping of valve body cavity.Rotational valve core 4 is processed by aluminium alloy compression casting, and rotational valve core 4 is processed into the precision of sealing with the sealing surface of stuffing box gland 3 butts.
Rotational valve core that the utility model is processed through hard material and the stuffing box gland processed by the soft material of teflon are realized the High-efficient Production of hand rotary valve under the prerequisite that guarantees airtight quality to substitute ceramic fixed spool.
More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
