Description
Technical field:
The present invention is relevant with the non-return and the stopper of the defeated pipe of liquid.
Background technique:
Be connected with rotary-open type or Lift check valve and stop valve on the liquid-discharging tube of pump, this covering device has following shortcoming:
1, rise-fall type and Swing check valve specifically do not open and close speed regulation function fully.
2, the flow condition in the dissymmetrical structure of up-down or Swing check valve and the valve is unfavorable for alleviating concussion and water attack.
3, liquid-discharging tube is not established vent valve, can not get rid of the concussion source, influences the working life of indusion tube.
4, safety check is can not Slow Close gentle opens, in the operating indusion tube fluid suddenly by with medium in contain portion gas, be prone to produce water attack, make indusion tube bear very big pressure and concussion.
Summary of the invention:
The object of the invention provides a kind of simple in structure, opens and closes the adjustable-speed joint, and the concussion that gas causes in can preventing to manage can prevent the indusion tube anti-water attack of the passive shuttle type that causes water attack, the rocking equipment of closing suddenly in service.
The present invention is achieved in that
Passive shuttle type of the present invention is prevented water attack, rocking equipment, on the indusion tube 2 of pump 1 safety check 3 is arranged, and safety check 3 is a shuttle type check valve; Its housing 4 one ends have intake pipe 5, and the other end has support 6, and support 6 is connected with shuttle cylinder 7; Piston 8 and piston rod 9 and shuttle cylinder 7 are movingly; Damping hole 10 on the piston 8 is connected with controlling device, and piston rod 9 is connected with the flap 11 of safety check, and the flap 11 of safety check is sealed and matched with the inner valve seat 14 of intake pipe 5; Said controlling device is the enlarged diameter section screw-thread fit of adjusting screw 33 and damping hole 10; The reduced diameter section of the tapered tip of adjusting screw 33 and damping hole 10 is sealed and matched, and adjusting screw 33 hollows are communicated with through the lumen of side opening 34 with damping hole 10.
Between the flap 11 of support 6 and safety check spring 12 is arranged.
Safety check 3 is connected with stop valve 36; There is arm 15 to be connected with the flange 18 of shuttle-type double-action vent valve 17 on the connecting pipeline through flange 16; Ring-shaped valve seats 19 is connected with the two between two flanges, and the flap 20 of shuttle-type double-action vent valve is positioned at and is sealed and matched with it below the ring-shaped valve seats 19, and some vents 21 are arranged on the flap 20 of shuttle-type double-action vent valve; Vent 21 and cylinder 23 are movingly; The upper end of cylinder 23 and spacing card 25 are connected, and lower end and half ball float 24 are connected, and the outer wall of cylinder 23 has axial groove 22; Be sealed and matched below the flap 20 of the plane of half ball float 24 and shuttle-type double-action vent valve; Supporting 27 in the housing 26 of the valve rod that is connected with the flap axle center of shuttle-type double-action vent valve 32 and vent valve 17 movingly, the valve rod 32 of vent valve also is connected with nut 29 with pad 28, spring 30 support 27 and pad 28 between and be enclosed within on the valve rod 32 of vent valve.
Shuttle type check valve of the present invention has following advantage:
1, the opening time can be adjusted, and can be stepless, also can be definite value.Slow startup can help preventing and treating the influence of gas concussion.
2, the shut-in time can be adjusted, and can be stepless, also can be definite value.The Slow Close function helps preventing and treating the influence of water attack.
3, shuttle type check valve can arbitrarily angledly be installed.
4, simple in structure, quiet, energy-conservation.
5, flow resistance is little, is applicable to Oil, Water, Gas and multiphase flow system.
Shuttle-type double-action vent valve of the present invention has following advantage:
1, shut down when pump, shuttle type check valve is closed, and when emptying indusion tube liquid storage, ball float sinks, and mends into air to indusion tube, prevents to form vacuum indusion tube is crushed.
2, the indusion tube that is in operation loses liquid suddenly, produces vacuum, and the barometric pressure flap is opened, and tonifying Qi rapidly prevents that indusion tube from being crushed.
3, the startup after operation or emptying indusion tube are shut down first, float sinks.Air in the discharge conduit is closed vent after having arranged.
4, the fragmentary air in the proper motion medium is discharged, the moment sink-float that float is sensitive.Promptly row promptly closes.
The present invention is simple in structure, and installation and easy to adjust can prevent that indusion tube from causing gas concussion and pressure to increase because of sending water and dehydration suddenly, makes the indusion tube flow resistance little, quiet, energy-conservation, long service life.
