Description
Technical field
The utility model relates to valve, and particularly a kind of flange form valve is at pressure test and the fixing and packoff that leaks hunting and use when checking.
Background technology
Various valves will carry out the pressure test and the check of leaking hunting after checking and accepting and keep in repair before making, installing, the two ends of valve need be sealed.Adopt following two kinds of methods at present:
1. need make many shroudings specially according to the bore of various valves, the size of working pressure, the manual then screw of tightening one by one, so both waste materials, it is time-consuming to require great effort again.
2. must on special-purpose test unit, be equipped with hydraulic cylinder, produce thrust, top tight sealing by piston rod.Its shortcoming is a hydraulic system cost height, operating maintenance trouble, and power consumption, poor stability; And, therefore be subjected to certain restriction for adapting to the adjustment of different pressure and bore needs.
Summary of the invention
Task of the present utility model provides the test of a kind of flange form valve with fixing and packoff, and it has solved at present in pressure test and need make shrouding when leaking hunting check or the problem of configuration hydraulic system thereby expense material, power consumption, operating maintenance trouble.
The technical solution of the utility model is as follows:
A kind of flange form valve test is with fixing and packoff, be installed in by card base on the support in the flange port outside, described carriage center is equipped with the central shaft that can move forward and backward, on the crown of central shaft, be equipped with and fill up the seal block that is placed on the flange port, the transmission nut that is connected with the support tail end is housed at the rear portion of central shaft, the conical gear group also is equipped with at rear portion at central shaft, the conical gear group is formed by gear wheel with the pinion wheel that gear wheel is connected with a joggle, gear wheel is connected by key with transmission nut, and pinion wheel is connected the handwheel axle head; The center of described central shaft and seal block is provided with the through hole of negotiable test(ing) medium, also is provided with the test(ing) medium introducing port that is communicated with this through hole on central shaft.
The utility model screws this device with handwheel by deceleration force amplifier and just can realize fixing and sealing.When valve need be done pressure test, load onto seal block, the movable card base of three-jaw is blocked flange, operating personnel rotate handwheel, slow down by the conical gear group, central shaft is moved, to flange port with top tight sealing cushion block and valve seal end, this moment, O-ring seal was pressed in the embeded slot, had played fixing and sealing function thus.
When valve is tested, feed test(ing) medium by the test(ing) medium introducing port, it is indoor that test(ing) medium process central shaft flows to tested valve cavity.Adopt valves test of the present utility model with fixing and packoff, the conical gear group is slowed down, increase moment of torsion, play the effect that increases axial force by rotating handwheel.
The utility model is a rigid structure, in the design strength scope, no matter valve aperture and pressure size can be fixed and seal.The utility model is cheap, has saved material; It is simple to operate, laborsaving, wide adaptability; The user has improved work efficiency, uses reliable.
Description of drawings
Accompanying drawing is the structural representation of a kind of flange form valve test of the present utility model with fixing and packoff.
Embodiment
Referring to accompanying drawing, the utility model is the test of a kind of flange form valve with fixing and packoff, and it is installed in by card base on the support 2 in the flange 1 port outside, and card base can adopt the movable card base 3 of three-jaw, during installation it is blocked flange 1 limit.
The central shaft 4 that can move forward and backward is installed at support 2 centers.Seal block 5 is installed on the crown of central shaft 4, and seal block 5 pads cover on 1 mouthful of flange.The transmission nut 6 that is connected with support 2 tail ends is housed at the rear portion of central shaft 4.
Be provided with the through hole 41,51 of negotiable test(ing) medium at the center of central shaft 4 and seal block 5, also be provided with the test(ing) medium introducing port 42 that is communicated with this through hole on central shaft 4, test(ing) medium can be passed in tested valve 9 chambers by this introducing port 42.
Head at central shaft 4 can be installed rubber seal 9.Seal block 5 can be installed O-ring seal 10 at an end that contacts with 1 mouthful of flange, O-ring seal 10 is installed can be prevented that test(ing) medium from leaking.
Claims (5)
1. a flange form valve test is with fixing and packoff, be installed in by card base on the support in the flange port outside, it is characterized in that, described carriage center is equipped with the central shaft that can move forward and backward, on the crown of central shaft, be equipped with and fill up the seal block that is placed on the flange port, the transmission nut that is connected with the support tail end is housed at the rear portion of central shaft, the conical gear group also is equipped with at rear portion at central shaft, the conical gear group is formed by gear wheel with the pinion wheel that gear wheel is connected with a joggle, gear wheel is connected by key with transmission nut, and pinion wheel is connected the handwheel axle head; The center of described central shaft and seal block is provided with the through hole of negotiable test(ing) medium, also is provided with the test(ing) medium introducing port that is communicated with this through hole on central shaft.
2. flange form valve test according to claim 1 is characterized in that with fixing and packoff the head of described central shaft is equipped with rubber seal.
3. flange form valve test according to claim 1 is characterized in that with fixing and packoff described seal block is equipped with the O-ring seal that prevents that test(ing) medium from leaking at an end that contacts with flange port.
