Abstract
The utility model relates to a liquid conveying valve field discloses a spiral valve body of ball, and including valve body, valve rod, case, the valve body is equipped with water inlet and delivery port, and water inlet and delivery port separate through the case, the lower extreme at the valve rod is connected to the case, in the valve body is located to the valve rod, in valve rod interlude and the valve body, be equipped with the ball between the thread of valve rod, be equipped with on the valve body with this ball roll assorted profile, the valve body is equipped with the ball passageway, becoming rolling friction with sliding friction, big thorough examination, having lacked frictional resistance, improved the transmission line spare of spiral, wearing and tearing also reduce simultaneously, have lengthened life.
Description
Technical field
The utility model relates to liquid carrying valve field.
Background technique
Manually-operated gate is controlling component in pipeline fluid transporting system, and it is used to change path section and media flow direction, has the functions such as water conservancy diversion, cut-off, adjustment, throttling, non-return, shunting or overflow release.For the valve that fluid controls, the inside nominal diameter of valve reaches greatly the industrial pipeline valve of 10m to latus rectum from atomic little Gauge Valves.Valve can under the effect of pressure, temperature or other form transducing signal, by pre-provisioning request action, or do not rely on transducing signal and simply open or close, valve rely on drive or automechanism makes open-shut device be elevated, slippage, swing or rotation motion, thus the size changing its Flow area is to realize its controlling functions.Traditional manually operated valve comprises valve body, valve rod, and threaded stem is connected in valve body, and valve rod bottoms liquid passage place is provided with spool, and by rotary valve rod, the position of spool is changed, and the size of regulates liquid passage, realizes the adjustment of fluid flow.In the production process of chemical reagent, strictly must control the amount of adding material, to the adjustment of valve body, there is high-precision requirement, but what current manually operated valve valve rod employing was common is threaded in valve body, screw thread in Long-Time Service process due to wearing and tearing, coordinate and become lax, had a strong impact on the degree of regulation of valve body.
Model utility content
The utility model is intended to provide a kind of degree of regulation high, the ball screw formula valve body of long service life.
Ball screw formula valve body in this programme, comprise valve body, valve rod, spool, described valve body is provided with water intake and water outlet, water intake and water outlet are separated by spool, and described spool is connected to the lower end of valve rod, and valve rod is located in valve body, described valve rod interts with in valve body, be provided with ball between the thread of described valve rod, described valve body is provided with and this ball the rolls profile matched, described valve body is provided with ball channel.
Beneficial effect: by rotary valve rod, makes valve rod move down, and allows the joint of spool shutoff entery and delivery port of valve rod bottom, realizes turning down of fluid flow; Compared with traditional being threaded, by establishing ball between the thread of valve rod, mechanism just can be able to be made to start work by little moment, can realize fine motion and not produce creeping phenomenon, transmission accuracy improves; Sliding friction is become rolling friction, greatly reduces surface friction drag, improve the transmission condition of spiral, wearing and tearing also reduce simultaneously, extend working life.
Further, described valve body outside is provided with conduit, and described conduit two ends are communicated with the ball channel on valve body, and conduit and ball channel form closed circulation, reduce the input amount of ball.
Further, the upper end of described valve rod is provided with rotating disk, more laborsaving, improves the simple operation of adjustment process.
Further, between described valve rod and valve body, sliding parts is provided with Sealing, prevents the leakage of chemical liquid.
Further, the material of described Sealing is asbestos, and a lot of chemical reagent is with acid, alkali or corrosivity, adopts the Sealing of asbestos material that chemical solution can be prevented the corrosion of Sealing, makes it lose seal action.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model ball screw formula valve body embodiment;
Fig. 2 is the structural representation of valve rod and valve body cooperation place in Fig. 1.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference character in Figure of description comprises: valve body 1, water intake 11, water outlet 12, valve rod 2, spool 21, ball 3, conduit 4, Sealing 5.
Embodiment is substantially as shown in Figures 1 and 2: the spiral valve body of this ball 3, comprise valve body 1, valve rod 2, spool 21, valve body 1 has water intake 11 and water outlet 12, water intake 11 and water outlet 12 are separated by spool 21, and spool 21 is threaded in the lower end of valve rod 2, and valve rod 2 is socketed in valve body 1, be interspersed in valve body 1, be covered with ball 3 between the thread of valve rod 2, valve body 1 be processed with and this ball 3 rolls the profile matched, valve body 1 is also processed with ball 3 passage.Valve body 1 is externally connected to conduit 4, ball 3 channel connection on conduit 4 two ends and valve body 1, and conduit 4 and ball 3 passage form closed circulation, reduce the input amount of ball 3.
The upper end rotating disk with bolts of valve rod 2, more laborsaving, improve the simple operation of adjustment process; Between described valve rod 2 and valve body 1, sliding parts is provided with Sealing 5.The material of Sealing 5 is asbestos, and a lot of chemical reagent is with acid, alkali or corrosivity, adopts the Sealing 5 of asbestos material that chemical solution can be prevented the corrosion of Sealing 5, makes it lose seal action.
Working procedure: by rotary valve rod 2, when valve rod 2 rotates, promote ball 3 and roll, ball 3, owing to being limited by the profile in valve body 1 again, cannot move, and valve body 1 is fixed, and causes valve rod 2 to move down; Allow the joint of spool 21 shutoff entery and delivery port 12 of valve rod 2 bottom, realize turning down of fluid flow; By being provided with ball 3 between the thread of valve rod 2, mechanism just can be able to be made to start work by little moment, can realize fine motion and not produce creeping phenomenon, transmission accuracy improves; Sliding friction is become rolling friction, large thorough examination, has lacked surface friction drag, improve the transmission condition of spiral, wearing and tearing also reduce simultaneously, extend working life.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
