Abstract
The utility model designs a liquid control oblique push type stop valve which uses an inclined plane which is arranged on a piston rod to realize the stop-typed opening and the stop-typed closing. The utility model comprises a valve body, a piston rod, an outlet hole, and an inlet hole. The utility model is characterized in that an inclined plane 7 is arranged on the piston rod 8, a stop-typed door rod 3 is arranged on a medium passage way, the upper end of the stop-typed door rod 3 is provided with a spring 2, and the lower end of the stop-typed door rod 3 pushes the inclined plane 7 on the piston rod. The utility model has the advantages of simple structure, reliable seal long service life, etc.
Description
The utility model belongs to valve type, is a kind of hydraulic control obique push type stop valve specifically.
At present during the down-hole coal excavation of colliery, be used to control the fluid-control valve of spray for dust suppression, roughly divide two classes: the structural principle of a class hydraulic control valve is the obstruction method: with the spool of a similar stopper, plug closes medium channel, though this valve is simple in structure, to use slightly long afterwards, sealability reduces, less than compensation, sealing loses reliability again; The structural principle of another kind of hydraulic control valve is the plunger method: move back and forth with a plunger, medium through hole is blocked or open-minded, this method since the Sealing on the plunger on medium holes, move for a long time, so one be wearing and tearing greatly, the 2nd, the possibility of damaging is at any time arranged in use, so performance is very unstable.
The purpose of this utility model then is the problem at above-mentioned existence, designs the hydraulic control obique push type stop valve that a kind of inclined-plane that uses piston rod to be provided with realizes that cut-off type opens and closes.
The utility model technical solution:
A kind of hydraulic control obique push type stop valve, it comprises valve body, piston rod, access hole is characterized in that piston rod 8 is provided with inclined-plane 7, is provided with cut-off type door bar 3 on medium channel, and there is spring 2 cut-off type door bar 3 upper ends, and the lower end heads on the inclined-plane 7 on the piston rod.
Advantage of the present utility model:
This valve adopts the inclined-plane to promote, and has realized the sealing means of hydraulic control valve use cut-off type, and suitable keying signal is 5 MPa to 30 MPa hydraulic pressure signal pressure, has opened up the user and has used, applies mechanically the extensive approach that other liquid that pressure is arranged is made keying signal liquid; This valve has reduced hoisting capacity owing to adopt the inclined-plane to open and close, so can be implemented on the basis of using stop valve, adopts the pressure medium direction refluence method identical with closing direction, makes sealing more reliable, and not influenced by pressure medium; This valve has reduced keying speed under the situation of high pressure keying signal liquid, reduced the damage of open-shut device to the percussion of sealing surface.So this valve not only has the advantage of cut-off type, non-return valve, and also have keying signal hydraulic coupling scope big, sealing is reliable, advantages such as long service life.
Fig. 1 is the utility model structural representation.
Below in conjunction with accompanying drawing model utility is further described:
Valve body 1 is the main body of valve.When start signal liquid when hand-hole 9 is pressed into the piston cylinder left end and promotes piston rod 8 and move right, inclined-plane 7 on the piston rod rises, promoting cut-off type door bar 3 rises, make the door of cut-off type door bar 3 upper ends leave sealing surface 10, medium enters from medium hand-hole 11, portal 4 by arriving medium between cut-off type door bar 3 and the sealing surface 10, at this moment this valve is in opening state.When shutdown signal liquid is pressed into piston cylinder right-hand member promotion piston rod 8 to left movement from hand-hole 6, inclined-plane 7 on the piston rod descends, under the effect of cut-off type door bar 3 spring 2 in the top, to decline, active force until inclined-plane 7 pairs of cut-off type doors bar 3 all disappears, cut-off type door bar 3 is pressed on the sealing surface 10, cuts off portal from medium hand-hole 11 to medium 4 path of medium, and valve is realized closed condition.At this moment act on pressure on the cut-off type door bar 3 except the pressure of spring 2, also have the pressure of a medium, and this pressure increases with pressure medium, make the reliability of sealing not influenced by pressure medium cut-off type door bar 3.This valve needs only to adjust regulates double-screw bolt 5 (regulate double-screw bolt 5 and be arranged at piston cavity one end), the stroke of control piston bar 8, thus the opening degree that can adjust cut-off type door bar 3 reaches the flow of control media by this valve, realizes this valve throttling action.When the user does not need to regulate rate-of flow, regulate double-screw bolt 5 and can omit.
