Abstract
The utility model relates to a kind of valve, especially a kind of crush seal gate valve.Comprise valve body, valve rod, flashboard, flashboard is arranged in valve body, flashboard is connected with valve rod, described flashboard is divided into substrate, crushing plate, substrate, crushing plate are a trapezoidal plate, the trapezoidal faces of substrate and crushing plate pieces together flashboard, and substrate is in below crushing plate, is provided with one for the movable chamber for flashboard movement in the bottom of valve body.Said structure utilizes substrate and increased pressure board to piece together a flashboard, flashboard is when cut out, stretch into movable chamber, substrate expands laterally under the extruding of crushing plate, extrude crushing plate in reaction simultaneously, the pressure of continuous increase seal ring position, reach good sealing effect, even if seal ring damages also can not affect sealing effect, therefore the working life of product is extended, due to this split structure staggered, even if there is any discrepancy for size, also this structure can be utilized to reach the effect of normal running sealing, because this reducing machining accuracy.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of crush seal gate valve.
Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification are quite various.Valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Valve is also divided into cast iron valve according to material, cast steel valve, stainless valve, Cr-Mo steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized material such as valve such as grade.
And current gate valve has single facer gate valve and dual face seals gate valve, single facer gate valve is needs actuators, flashboard is subjected to displacement thus reaches the object of closing sealing, and two way sealed is the two-sided sealing configuration that all adds of flashboard, because flashboard is subject to the impact of pressure medium when opening and closing, therefore be difficult to guarantee linear movement, often there will be the situations such as seal structure damage, and the gate valve of one-way sealing, also easily damage for a long time, the problem of same existence sealing, thus the working life of gate valve is declined, and in order to seal, need the precision of making also higher.
Summary of the invention
The purpose of this utility model is, provides that a kind of required precision is low, the crush seal gate valve of sealing effect, long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of crush seal gate valve, comprise valve body, valve rod, flashboard, flashboard is arranged in valve body, flashboard is connected with valve rod, described flashboard is divided into substrate, crushing plate, and substrate, crushing plate are a trapezoidal plate, and the trapezoidal faces of substrate and crushing plate pieces together flashboard, substrate is in below crushing plate, is provided with one for the movable chamber for flashboard movement in the bottom of valve body.
This arranges and utilizes substrate and increased pressure board to piece together a flashboard, flashboard is when cut out, stretch into movable chamber, substrate expands laterally under the extruding of crushing plate, extrude crushing plate in reaction simultaneously, the pressure of continuous increase seal ring position, reach good sealing effect, even if seal ring damages also can not affect sealing effect, therefore the working life of product is extended, due to this split structure staggered, even if there is any discrepancy for size, also this structure can be utilized to reach the effect of normal running sealing, because this reducing machining accuracy.
Of the present utility modelly to be set to further: on described substrate trapezoidal inclined plane, be provided with a chute, crushing plate trapezoidal inclined plane is provided with a slide block, slide block and chute clamping, slide block slides in chute.
This arranges and utilizes slide block and the structure of chute to complete splicing to be connected, so can to ensure when depressed stem that the split structure direction of flashboard is consistent, can not produce skew, while can ensure the basic synchronization action of substrate and crushing plate.
Of the present utility modelly to be set to further: described valve rod head is a dop, crushing plate is provided with a pressure chamber, and dop is stuck in pressure chamber, be provided with at substrate top one with the catch of pressure chamber adaptation, press chamber to coordinate with catch dop is stuck in and press in chamber.
This is arranged on crushing plate and is provided with pressure chamber, and baffle plate is set on substrate, when unlatching, can ensure that substrate and crushing plate rise simultaneously, and when closing, the pressure of valve rod can be made all to act on crushing plate, make crushing plate fully carry out extruding action, simultaneously can the maximizing efficiency of guarantee effect power.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment;
Fig. 2 is the structural representation of flashboard.
Embodiment
With reference to figure 1, Fig. 2 is known, a kind of crush seal gate valve of the utility model, comprise valve body 1, valve rod 3, flashboard 2, flashboard 2 is arranged in valve body 1, flashboard 2 is connected with valve rod 3, described flashboard 2 is divided into substrate 21, crushing plate 22, substrate 21, crushing plate 22 is a trapezoidal plate, substrate 21 pieces together flashboard 2 with the trapezoidal faces of crushing plate 22, substrate 21 is in below crushing plate 22, one is provided with for the movable chamber 11 for flashboard 2 movement in the bottom of valve body 1, described substrate 21 trapezoidal inclined plane is provided with a chute 211, crushing plate 22 trapezoidal inclined plane is provided with a slide block 221, slide block 221 and chute 211 clamping, slide block 221 slides in chute 211, described valve rod 3 head is a dop, crushing plate 22 is provided with a pressure chamber 222, dop is stuck in pressure chamber 222, be provided with at substrate 21 top one with the catch 212 of pressure chamber 222 adaptation, pressure chamber 222 coordinates dop to be stuck in presses in chamber 222 with catch 212.
Obviously, above-described embodiment is only used to done citing is clearly described, and the restriction not to mode of execution.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of extending out or variation be still in protection domain of the present utility model.
