Description
Technical field
The utility model relates to valve manufacture field, specifically the detachable cut-off throttle valve of a kind of valve seat.
Background technique
Throttle valve is by changing throttling cross section or chock length to control the valve of fluid flow.Be promote flap to go to blind off a line near valve seat mostly at current common cut-off throttle valve on the market, then drive the rotation of flap to open by rotary valve rod.But in this pattern, easily there are wearing and tearing in valve rod and valve seat in long-term opening-closing process, and wearing and tearing after valve rod and valve seat drive flap rotate time, if there is flap deflection, valve seat cannot produce seal action, just easily produces leakage, particularly in the recovery process of shale gas, due to its high pressure operating mode, extremely easily bring potential safety hazard.
Model utility content
The utility model aims to provide the detachable cut-off throttle valve of a kind of valve seat, takes non-selection formula mode to open and close, to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
The detachable cut-off throttle valve of a kind of valve seat, is characterized in that: comprise valve body, sleeve and the valve rod be arranged in valve body, be connected to valve stem end flap; Roundabout medium fluid passage is provided with in described valve body; Described flap lower end has been connected by screw metal seat valve, metal seat valve and valve body are fitted and are formed metal hard-sealing, be formed with groove between metal seat valve outer peripheral surface and flap, be provided with triangle explosion-proof sealing ring in groove, explosion-proof sealing ring and valve body contact form soft seal; Described flap, between sleeve and valve body three, be provided with oil sealing space, and be connected with the oil delivering device with the conducting of oil sealing space in valve body side; Described valve stem end is provided with limiting stopper, and flap has been threaded flap gland, and flap coordinates relative with valve rod fixing by flap gland with limiting stopper; Described flap is flexibly connected with sleeve, and flap and barrel contacts circumferential surface have at least two and place the annular groove sealing O shape and enclose, and are provided with storage slag chute between two annular grooves.
Further, described flap lower end surface excircle is provided with scrapes slag cutting edge, scrapes slag cutting edge laminating tubular valve pocket.
Further, described sleeve is provided with throttling groove near media outlet side.
The beneficial effects of the utility model are:
One, the utility model is provided with storage slag chute, can put sliding seal ring by Protective valve, scrape slag cutting edge simultaneously under setting up flap, removes medium foul and is attached to bottom, valve pocket chamber, produce the situation of jam downwards when can prevent flap from closing.
Two, secondly, flap, between sleeve and valve body three, be provided with oil sealing space, and be connected with the oil delivering device with the conducting of oil sealing space in valve body side, when throttle down, by oil delivering device to injection liquid force feed in oil sealing space, flap is pressed down under pressure, until even at the cost of one's life on valve body, flap end and valve body form metal hard-sealing.When Open valve, the hydraulic oil in oil sealing space is laid down by oil delivering device, promote flap and valve rod to move compression oil sealing space under the effect of flowing medium, until flowing medium can flow into media outlet by throttling groove, valve rod is without the need to rotating, reduce the wearing and tearing between valve rod and flap, and it is more fast and simple to open and close valve.
Three, again, valve seat of the present utility model is detachable, and is formed with groove between metal seat valve outer peripheral surface and flap, triangle explosion-proof sealing ring is provided with in groove, can and valve body between form soft or hard double seal, not only convenient disassembly, and sealing effect is better.
Accompanying drawing explanation
Fig. 1 is the detachable cut-off throttle valve structural representation of valve seat that the utility model provides.
Mark in figure: 1 for valve body, 2 for valve rod, 3 for flap gland, 4 for limiting stopper, 5 for oil delivering device, 6 for throttling groove, 7 for valve seat, 8 for oil sealing space, 9 for flap, 10 for explosion-proof sealing ring, 11 for storage slag chute.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1, the detachable cut-off throttle valve of a kind of valve seat 7, comprises valve body 1, sleeve and the valve rod 2 be arranged in valve body 1, is connected to valve rod 2 end flap 9; Roundabout medium fluid passage is provided with in described valve body 1; Described flap 9 lower end has been connected by screw metal seat valve 7, metal seat valve 7 and valve body 1 are fitted and are formed metal hard-sealing, be formed with groove between metal seat valve 7 outer peripheral surface and flap 9, be provided with triangle explosion-proof sealing ring 10 in groove, explosion-proof sealing ring 10 contacts with valve body 1 and forms soft seal; Described flap 9, between sleeve and valve body 1 three, be provided with oil sealing space 8, and be connected with the oil delivering device 5 with oil sealing space 8 conducting in valve body 1 side; Described valve rod 2 end is provided with limiting stopper 4, and flap 9 has been threaded flap gland 3, and flap 9 coordinates relative with valve rod 2 fixing by flap gland 3 with limiting stopper 4; Described flap 9 is flexibly connected with sleeve, and flap 9 and barrel contacts circumferential surface have at least two and place the annular groove sealing O shape and enclose, and is provided with storage slag chute 11 between two annular grooves.Described flap 9 lower end surface excircle is provided with scrapes slag cutting edge, scrapes slag cutting edge laminating tubular valve pocket.Described sleeve is provided with throttling groove 6 near media outlet side.
