Abstract
The utility model discloses a valve, including valve body and valve rod, be equipped with the restriction dish on the valve body, a plurality of restriction portions have been seted up on the restriction dish, be equipped with the locking piece on the valve rod, locking piece and restriction portion phase -match through the cooperation with the locking piece of restriction portion, reach the purpose of accurate a valve flow, and setting up of a plurality of restriction portions make the locking piece in cooperating with each restriction portion, corresponding rotation to the fixed position of valve rod, thus reach and make the flow to control to through the cooperation of locking piece with restriction portion, can prevent that the valve rod from being touched easily after having transferred the position, and lead to the flow change.
Description
Technical field
The utility model relates to a kind of valve.
Background technique
Valve is in fluid system, be used for controlling the direction of fluid, pressure, flow device be the medium in pipe arrangement and equipment (liquid, gas, powder) is flowed or stops and the device of its flow can be controlled.Valve 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, throttling, non-return, shunting or overflow release.
At present, valve on market is all the effect directly being reached the passage of opening and closing by the keying of valve rod control flap, but, this valve accurately can not control the size of flow in pipeline, thus may be inconvenient due to can not controlling of flow in the process of follow-up use, therefore, need to provide a kind of valve that accurately can control pipeline flow.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of valve; This valve can control the size of flow.
For achieving the above object, the utility model provides following technological scheme: a kind of valve, comprises valve body and valve rod, described valve body is provided with confinement plate, described confinement plate offers some limiting units, and described valve rod is provided with latch, and described latch and limiting unit match.
The utility model is set to further: described limiting unit is formed primarily of some draw-in grooves, and described latch coordinates with draw-in groove, and described valve rod is provided with the locking mechanism for locking latch.
The utility model is set to further: described locking mechanism comprises and being arranged on valve rod for limiting the circle band of latch glide direction, described circle band offers through hole, described latch is located in through hole, described latch is provided with flange, described latch is arranged with spring, and described both ends of the spring is conflicted with flange and circle band respectively and is connected.
The utility model is set to further: described latch one end coordinates with draw-in groove, and the other end is provided with the shifting part facilitating mobile latch.
The utility model is set to further: described confinement plate is provided with the positioning block for limiting valve rod slewing area.
Compared with prior art, the utility model is coordinated by limiting unit and latch, reach the object of accurate valve flow, and some limiting units be arranged so that latch is when coordinating with each limiting unit, what valve rod was corresponding turns to fixing position, reaches thus flow can be controlled, and coordinating by latch and limiting unit, can prevent valve rod from being touched easily after mixing up position, and cause flow to change.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the utility model embodiment one;
Fig. 2 is the structural drawing in A direction in Fig. 1;
Fig. 3 is the structural drawing of the utility model embodiment two;
Fig. 4 is the structural drawing in B direction in Fig. 3.
Reference character: 1, valve body; 2, valve rod; 3, confinement plate; 31, draw-in groove; 4, latch; 5, positioning block; 6, circle band; 7, flange; 8, spring; 9, fluctuate part.
Embodiment
Referring to figs. 1 through Fig. 4, a kind of valve embodiments of the utility model is described further.
Embodiment one: as shown in Figure 1 to Figure 2, a kind of valve, comprise valve body 1 and valve rod 2, valve body 1 is provided with confinement plate 3, confinement plate 3 offers some limiting units, valve rod 2 is provided with latch 4, latch 4 and limiting unit match, by coordinating of limiting unit and latch 4, reach the object of accurate valve flow, and some limiting units be arranged so that latch 4 is when coordinating with each limiting unit, what valve rod 2 was corresponding turns to fixing position, reach thus flow can be controlled, and by coordinating of latch 4 and limiting unit, can prevent valve rod 2 from being touched easily after mixing up position, and cause flow to change.
Limiting unit is made up of some draw-in grooves 31, latch 4 coordinates with draw-in groove 31, and valve rod 2 is provided with the locking mechanism for locking latch 4, is reached the object of adjust flux by the cooperation of draw-in groove 31 and latch 4, and after guaranteed flow regulated, can not can be changed easily by locking structure.
Locking mechanism comprises and being arranged on valve rod 2 for limiting the circle band 6 of latch 4 glide direction, circle band 6 arranges two, and on circle band 6, offer through hole, latch 4 is located in through hole, latch 4 is provided with flange 7, latch 4 is arranged with spring 8, conflict with flange 7 and circle band 6 respectively and be connected in spring 8 two ends, draw-in groove 31 is arranged on the edge of confinement plate 3, now, spring 8 is arranged on latch 4 one end away from confinement plate 3, by the elastic force of spring 8 pairs of latchs 4, latch 4 is coordinated with draw-in groove 31, latch 4 end is provided with the end that draw-in groove 31 matches, guarantee draw-in groove 31 coordinates with latch 4.
Latch 4 one end coordinates with draw-in groove 31, and the other end is provided with the shifting part facilitating mobile latch 4, and fluctuation part 9 is arranged with now vertical with latch 4, conveniently pulls latch 4, thus facilitates coordinating of unlocked part 4 and draw-in groove 31.
Confinement plate 3 is provided with the positioning block 5 for limiting valve rod 2 slewing area, two positioning blocks 5 are set, the angle that restriction valve rod 2 rotates, positioning block 5 is vertical with confinement plate 3 to be arranged, thus the angle making valve rod 2 rotate is limited, in addition, positioning block 5 also can arrange one piece on valve rod 2, the confinement block matched with positioning block 5 is set simultaneously in confinement plate 3, reaches the effect of locking.
Embodiment two: as shown in Figure 3 to Figure 4, the place different from embodiment one is, limiting unit comprises sliding-groove, and the draw-in groove 31 be arranged in sliding-groove, at this moment, latch 4 one end is provided with projection, is coordinated with draw-in groove 31 by projection, and spring 8 is arranged on the one end near draw-in groove 31, at this moment, shifting part is arranged to end cap, and pressing end cap, makes latch 4 be separated with draw-in groove 31, finally reach the object of separation, and generally, by the elastic force of spring 8, projection is coordinated with draw-in groove 31, reach the effect of locking.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
