Description
Technical field
The utility model relates to a kind of anti-leak oil pipe valve bodies of high stable.
Background technique
Petroleum pipeline, large-scale gas pipeline require to use work of the various valve bodies to play switch on and off on wind power flange
With, but the sealing performance of common valve body and valve deck tends not to reach requirement, and valve body due to channel it is smaller, oil gas is logical
Speed when crossing valve body is slower, and when multipass valve body will significantly affect the speed of oil transportation, gas transmission.
Utility model content
The utility model lies in that overcome above-mentioned deficiency, it is good to provide a kind of sealing effect, the anti-leak of the high stable of anti-leak
Oil pipe valve body.
A kind of anti-leak oil pipe valve body of high stable, including valve body, the inside of valve body are fixed with valve seat, are provided with oil on valve seat
Road through-hole, the two ends of oil circuit through-hole are in horn mouth, wherein bell-mouthed internal bore is greater than external bore, the valve seat and valve
It is provided with valve seat insert between body, spool is provided among valve seat, the oil circuit through-hole of the valve seat is set respectively at two close end
Be equipped with a device for preventing leakage, which is check valve, and device for preventing leakage covers in oil circuit through-hole, device for preventing leakage with
Sealing ring is provided between valve body, the check valve valve body of check valve and the inner wall of valve body are clamped, the inner elements of check valve electricity of check valve
Magnetic control is opened and closed, and is provided with valve deck at the top of the valve body, which is flexibly connected with valve body, and the bottom of valve deck offers a circle
The groove of annular is provided with valve bonnet seal circle in groove.
The beneficial effects of the utility model are:
The anti-leak oil pipe valve body of this high stable, while valve seat insert is provided between valve seat and valve body, it seals
Property is preferable, and high-low pressure can leakproof；The two ends of the intermediate throughholes of valve seat are horn mouth, and the inside bore of mouth is greater than external port
Diameter ensure that the speed of oil transportation, gas transmission to improve the oil drain quantity of valve body；It is offered at the bottom of valve deck and valve body contact
The groove of one ring shape is provided with sealing ring in groove, and the leakproofness between valve body and valve deck can be improved in sealing ring, valve seat
Oil circuit through-hole is provided with device for preventing leakage in end point, and device for preventing leakage is check valve, when oil pipe closes check valve when not in use
Just leakage can be placed, ensure that the sealing performance of valve body.
Detailed description of the invention
Fig. 1 is the anti-leak oil pipe valve body figure of the utility model high stable.
Fig. 2 is the bottom substance schematic diagram of valve deck in Fig. 1.
Wherein: valve body 1, valve seat 2, oil circuit through-hole 2.1, valve seat insert 3, spool 4, device for preventing leakage 5, valve deck 6, groove
7, valve bonnet seal circle 8.
Specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model relates to the anti-leak oil pipe valve body of high stable, including valve body 1, valve body 1
Inside is fixed with valve seat 2, and oil circuit through-hole 2.1 is provided on valve seat 2, and the two ends of oil circuit through-hole 2.1 are in horn mouth, wherein loudspeaker
The inside bore of mouth is greater than external bore, ensure that oil gas is not slowed down by speed when valve seat 2, to improve the row of valve body 1
Oil mass ensure that the speed of oil transportation, gas transmission, valve seat insert 3 be provided between the valve seat 2 and valve body 1, is set among valve seat 2
It is equipped with spool 4, the oil circuit through-hole 2.1 of the valve seat 2 is provided with a device for preventing leakage 5, the anti-leak at two close end respectively
Device 5 is check valve, and 5 sets of device for preventing leakage in oil circuit through-hole 2.1, are provided with sealing between device for preventing leakage 5 and valve body 1
Circle, the check valve valve body of check valve and the inner wall of valve body 1 are clamped, and oil pipe is worked as in the inner elements of check valve Electromagnetic Control opening and closing of check valve
Closing check valve when not in use just can place leakage, ensure that the sealing performance of valve body.The top of the valve body 1 is provided with valve deck
6, which is flexibly connected with valve body 1, and the bottom of valve deck 6 offers the groove 7 of a ring shape, and it is close to be provided with valve deck in groove 7
The leakproofness between valve deck 6 and valve body 1 can be improved in seal 8, valve bonnet seal circle 8.
