Abstract
The invention discloses an improved valve clack component for a throttling cut-off emptying valve and belongs to the field of valves. The improved valve clack component for the throttling cut-off emptying valve comprises a valve clack, a valve bush, a valve base, a compression ring and a soft seal ring, wherein the peripheral surface, in contact with the valve bush, of the valve clack is provided with at least two ring grooves in which O-shaped seal rings are arranged; a slag storage groove is formed between the two ring grooves; the lower outer periphery of the valve clack is also provided with a slag-scraping knife edge which is attached to the drum-shaped valve bush; the lower end surface of the valve clack is provided with a threaded blind hole; the compression ring and the valve clack are fixed together by virtue of a screw; the soft seal ring is arranged between the compression ring and the valve clack. The improved valve clack component can be used for effectively realizing the self-function protection effect.
Description
Technical field
The present invention relates to valve field, specifically a kind of modified model choke stop evacuation valve flap assembly.
Background technique
Choke stop evacuation valve is a kind of double seal valve, plays in the conveyance conduit being mainly used in oil, rock gas, coal gas, blau gas etc., uses usually used as regulable control or cut-out.Such valve is a kind of novel throttling, cut-off, emptying product, has multistage throttle effect, the features such as restriction effect is obvious, sealing is reliable, convenient operating maintenance.
At existing choke stop evacuation valve in the throttling of valve, cut-out, equalizing orifice arranges to alleviate in operation torsion, combination seal etc. all very much progress.But in actual conditions application, still there are distinct issues: be mainly reflected in the valve good operation period not long, bad working environments occurs that quality problems are many.Particularly when High Pressure Difference, operating mode medium unholiness (such as, dust, body refuse etc.), general valve seal easily damages and occurs that the situation of interior leakage is more, and even serious jam appears in some valve.Tracing it to its cause, it is not exclusively reasonable to be mainly structural design: although valve design function all has configuration, and in fact its Functional Design structure can not extensively be suitable for, and its structure exists wretched insufficiency in self function and protecting.
Summary of the invention
The present invention aims to provide a kind of modified model choke stop evacuation valve flap assembly, to solve the problem of self function and protecting.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of modified model choke stop evacuation valve flap assembly, it is characterized in that: described flap assembly comprises flap, valve pocket, valve seat, pressure ring, soft seal circle, flap contacts circumferential surface and has at least two and place the annular groove sealing O shape and enclose with tubular valve pocket, be provided with storage slag chute between two annular grooves; Under described flap, excircle is also provided with and scrapes slag cutting edge, and scraping slag cutting edge is arc-shaped, laminating tubular valve pocket, and flap lower end surface has tapped blind hole; Described pressure ring is provided with the conical surface, and the conical surface of pressure ring is divided into two sections, is also provided with boss between two sections of conical surfaces, and the pressure ring conical surface and the flap conical surface form step conic, adaptive with the step conical surface on valve seat; Described pressure ring screw and flap are fixed, and are provided with soft seal circle between pressure ring and flap.
Further, described valve clack sealing surface is taper, built-up welding or be coated with wear-resisting, anticorrosive hard alloy layer or Tungsten carbite hardstanding.
Further, described flap flap gland is relative with valve rod fixing, is provided with thrust bearing between flap and valve rod, also has the equalizing orifice connecting valve body upper cavity and lower chamber in flap.
Further, described soft seal circle is explosion-proof triangle fluorine rubber ring, and sealing surface is taper.
Beneficial effect of the present invention is:
One, soft, the hard sealing surface of flap soft seal circle is conical seal (contact) face, and conical seal (contact) face is beneficial to purging, the foul easily on removal sealing surface, is unfavorable for that foreign material are piled up or deposition, and is very easy to purge totally, prevent sealing surface extruded by hard object or scratch.
two,adopt pressure ring to coordinate with valve seat thus form slow nip structural design.Valve opening moment, hard, soft sealing face that flap, soft seal circle and valve seat are formed successively are thrown off, and in this process, the boss of pressure ring forms slow nip with the segment length that coordinates of the interior step of valve seat.Slow nip structural design, prevent valve open/close moment soft seal from being torn by high pressure, prevent high pressure valve from opening and closing moment simultaneously, easily the problem in damage soft seal face, ensure that this structure is applicable to the reliability of high, medium and low voltage simultaneously.
Be provided with storage slag chute between two O-ring seals three, on flap cylindrical, sliding seal ring can be put by Protective valve, under setting up flap, scrape slag cutting edge simultaneously, remove medium foul and be attached to bottom, valve pocket chamber, when can prevent flap from closing, produce the situation of jam downwards.
Accompanying drawing explanation
Fig. 1 is the structural representation of modified model choke stop evacuation valve flap assembly provided by the invention.
Fig. 2 adopts modified model choke stop evacuation valve of the present invention.
Mark in figure: 3 for valve seat, 7 for screw, 8 for pressure ring, 9 for soft seal circle, 10 for flap, 12 for tubular valve pocket, 13 for flap gland, 14 for valve rod, 30 for flap annular groove, 32 for the pressure ring conical surface, 33 for the flap conical surface, 37 for scraping slag cutting edge, 40 equalizing orifices.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1, a kind of modified model choke stop evacuation valve flap assembly, it is characterized in that: described flap assembly comprises flap 10, valve pocket 12, valve seat 3, pressure ring 8, soft seal circle 9, flap 10 contacts circumferential surface and has at least two and place to seal between annular groove 30, two annular grooves 30 that O shape encloses and be provided with storage slag chute with tubular valve pocket 12; Described flap 10 times excircles are also provided with scrapes slag cutting edge 37, and scrape slag cutting edge 37 and to fit tubular valve pocket 12, flap 10 lower end surface has tapped blind hole; Described pressure ring 8 screw 7 and flap 10 are fixed, and are provided with soft seal circle 9 between pressure ring 8 and flap 10.Described flap 10 sealing surface is taper, built-up welding or be coated with wear-resisting, anticorrosive hard alloy layer or Tungsten carbite hardstanding.Described flap 10 is relative with valve rod 14 fixing with flap gland 13, is provided with thrust bearing between flap 10 and valve rod 14, also has the equalizing orifice 40 connecting valve body upper cavity and lower chamber in flap 10.Described pressure ring 8 is also provided with the conical surface, and the conical surface of pressure ring 8 is divided into two sections, is also provided with boss between two sections of conical surfaces, and the pressure ring conical surface 32 and the flap conical surface 33 form step conic, adaptive with the step conical surface on valve seat 3.Described soft seal circle 9 is explosion-proof triangle fluorine rubber ring, and sealing surface is taper.
