Abstract
The utility model discloses a friction locating device for a multiway valve. The friction locating device comprises a gland fixed on a valve body, and a locating seat matched with the gland, wherein a blind hole is axially arranged in the locating seat; a locating joint lever matched with the locating seat and axially moving in the blind hole of the locating seat is arranged in the blind hole. The friction locating device is characterized in that at least one through hole is arranged radially in the locating seat; a steel ball, a spring and a spring seat are sequentially arranged in the through hole from inside to the outside, and the spring seat is fixedly connected with the locating seat. Because the steel ball rubs and rolls on the surface of the locating joint lever by the action of the spring, when a valve rod of the multiple valve is moved to a random position within a range of travel and stops, enough friction resistance is generated between the steel ball and the locating joint lever to keep the valve rod still. As a result, the locating effect can be improved very well.
Description
Technical field
The utility model relates to the control gear of hydraulic multitandem valve, more particularly relates to a kind of multi-way valve friction positioning device.
Background technique
Existing hydraulic multitandem valve is many by manual control, can only when needing the multi-way valve valve rod to remain on any one station long-term work, must grasp handle in certain several special positions location, is easy to fatigue.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of multi-way valve friction positioning device, the technological scheme that it adopts is: a kind of multi-way valve friction positioning device, comprise the gland that is fixed on the valve body, the positioning seat that cooperates with gland, positioning seat axially is provided with blind hole, be provided with in the blind hole with positioning seat adaptive and can be in the positioning seat blind hole axially movable positioning link bar, it is characterized in that: described positioning seat radially is provided with at least one through hole, be disposed with steel ball in the through hole from inside to outside, spring, and it is spring seat, and fixedly connected between spring seat and the positioning seat.
The utility model further technical characteristics is:
Be to be threaded or to weld between described spring seat and the described positioning seat.
Described positioning link bar left end is provided with annular boss, and the centre is provided with annular groove, and right-hand member is provided with outside thread.
Between described gland and the positioning seat, and be provided with seal ring between spring seat and the positioning seat.
The beneficial effects of the utility model are: the valve rod of the described in actual applications location of the utility model connecting rod right-hand member and multi-way valve is connected, because described positioning seat radially is provided with at least one through hole, be disposed with steel ball, spring and spring seat in the through hole from inside to outside, and it is fixedly connected between spring seat and the positioning seat, therefore spring can be oppressed steel ball and produce big resistance on positioning link bar, prevention is moved with the valve rod that the location connecting rod links to each other, and therefore can play good positioning action.When the valve rod of multi-way valve overcomes resistance and moves axially, positioning link bar together moves, steel ball rolls in the positioning link bar surface friction under spring action, when the valve rod with multi-way valve moves to that the arbitrary position stops in the stroke range, can produce enough surface friction drag between steel ball and the positioning link bar and make valve rod keep static.Therefore can improve locating effect well.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by specific embodiment.
As shown in Figure 1, a kind of multi-way valve friction positioning device, comprise the gland 1 that is fixed on the valve body, the positioning seat 2 that cooperates with gland 1, positioning seat 2 axially is provided with blind hole 21, be provided with in the blind hole 21 with positioning seat 2 adaptive and can be in positioning seat blind hole 21 axially movable positioning link bar 3, wherein, described in the present embodiment positioning seat 2 radially is provided with a through hole 22, be disposed with steel ball 4, spring 5 and spring seat 6 in the through hole 22 from inside to outside, and fixedly connected between spring seat 6 and the positioning seat 2.
Being to be threaded between spring seat described in the present embodiment 6 and the described positioning seat 2 in addition, can also be welding or other fixedly connected modes.And in order to satisfy practical application better, described positioning link bar 3 left ends of present embodiment are provided with annular boss 31, and the centre is provided with annular groove 32, and right-hand member is provided with the outside thread 33 that links with multi-way valve valve rod (not shown).Equally, in order to reach good sealing effect, between described gland 1 and the positioning seat 2, and be provided with seal ring 7 between spring seat 6 and the positioning seat 2.Present embodiment in actual applications, when when valve rod that positioning link bar 3 axially is connected at right-hand member is in meta (multi-way valve is in meta), spring 5 in the spring seat 6 has certain decrement, make steel ball 4 be stuck in annular groove 32 positions that are provided with in the middle of the positioning link bar 3, produce big resistance, stop valve rod to move, another effect of annular groove 32 is the meta position of more significantly determining multi-way valve.When valve rod overcomes resistance and moves axially, positioning link bar 3 together moves, steel ball 4 breaks away from groove 32, spring 5 further is compressed, make steel ball 4 press to positioning link bar 3 surfaces, and can when valve rod be moved to the arbitrary position stops in the stroke range, between steel ball 4 and positioning link bar 3, produce enough surface friction drag and make valve rod keep static.
The design of this location connecting rod 3 is to design in order to satisfy specific needs; do not limit protection domain of the present utility model; as long as the frictional force between steel ball 4 and the location connecting rod 3 can satisfy the location needs, the form of any location connecting rod 3 is all within protection domain of the present utility model.In addition, in the practical application, gland 1 is connected with valve body by mounting hole 11.
Fig. 2 is another an embodiment's of the present utility model structure sectional view, in the present embodiment, except Fig. 1 embodiment's characteristics, present embodiment positioning seat 2 radially is provided with two through holes 22, be disposed with steel ball 4, spring 5 and spring seat 6 in the through hole from inside to outside, and fixedly connected between spring seat 6 and the positioning seat 2.By the increase of positioning seat 2 radial direction through hole 22, can increase the number of steel ball 4 and spring 5, can increase the frictional force between steel ball 4 and the location connecting rod 3 equally, thus can be to improve locating effect.Certainly, positioning seat 2 radial direction through hole 22 can also evenly be arranged to 3 or 4, but purpose all is to increase the frictional force between steel ball 4 and the positioning link bar 3, thereby the raising locating effect.
