Abstract
An antivibration device of pressure gauge for elongating its service life greatly has a connector body with system connecting part. Locating part and pressure gauge are sequentially installed to the connector body which has internal screw to match with screw bolt having buffer cavity for forming a screw damping segment. Said connector body may be replaced by pressure gauge connector in which said screw bolt is set up. It features easy manufacture and simple structure.
Description
The invention belongs to vibration abatement for pressure gauge.
Be used for pressure system and indicate the tensimeter of pressure medium, must bear the pressure pulse of distinct program, under bad working environments, must cause indication shakiness, tensimeter premature damage especially.At present corresponding countermeasure then is in the dependence meter connector damping hole to be set to alleviate pulse or set up the pressure meter switch valve.By on-off valve control pressing pressure table, carry out of short duration, now examine off and on and indicate, to improve the life-span of table.Nonetheless, under the situation of the acute row of vibrations, in the hydraulic system of recognizing the high pressure of pressing jackdrill, high impulse at similar liquid, the shockproof tensimeter that uses deploy switch valve more still is difficult to normal long-term the use at present.
Task of the present invention is to provide a kind of vibration abatement to the pressure medium table, and it is simple for structure, easy to manufacture, easy for installation, makes tensimeter indicate stable under extremely abominable operating mode; Need not be by switch valve, and greatly improve serviceable life.
For solving above-mentioned task, the method that the present invention adopts is: utilize the appropriate clearance that obtains after the threaded engagement, promptly cause a kind of thin and long damping wire, pressure pulse transmits in this damping wire, reduces gradually so that disappear.Device is made up of fittings body and cooperation double-screw bolt etc.The fittings body subsystem connects, table connects, cushion chamber, cooperates functional parts such as interior spiral shell.Cooperate double-screw bolt because of its Major Diam less than the big footpath of spiral shell in cooperating, its screw thread path is less than spiral shell path in cooperating, both pitch rotation direction unanimities are so after it revolved cooperation, the screw thread root then formed certain gap between screw between pushing up, i.e. the spiral damping line.The cross section of damping wire and length can be determined by request for utilization, and are cooperated spiral shell spare size, pitch and cooperated the adjustability of double-screw bolt to finish by control.The spiral damping line also can be caused after cooperating by single cooperation spiral shell spare, but preferably as above-mentioned join to revolve cause, cooperate that on the double-screw bolt cushion chamber effect to be set better, cooperate double-screw bolt to locate by keeper.In said structure, fittings body also can be replaced by pressure tapping, and counterpart can directly be arranged in the pressure tapping.
This device is compared with traditional stubby straight-through damping hole device that utilizes, because of its damping wire cross section can be by cooperating double-screw bolt size Control, its length to be determined by the length of fit and the pitch that cooperate double-screw bolt, so can cause very thin very long spiral damping line; When pressure pulse process spiral damping line, then be subjected to corresponding resistance, become when being delivered on the pressure gauge component steadily, thereby shockproof effect is very remarkable.
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
Accompanying drawing 1 is the phantom view of joint type vibration abatement for pressure gauge.
Accompanying drawing 2 is phantom views of direct-type vibration abatement for pressure gauge.
Embodiment one: the joint type vibration abatement for pressure gauge.
Present embodiment comprises fittings body (1-7) and cooperates double-screw bolt (1-4).Fittings body (1-7) has system's connecting portion to be connected with system body (1-3), after the interior spiral shell (1-2) of cooperation being arranged and cooperating double-screw bolt (1-4) to cooperate, then forms one section spiral damping line.From the top of fittings body (1-7), behind pack into successively keeper (1-6), the tensimeter, then fuse with system body (1-3).Cooperate double-screw bolt (1-4) also to have cushion chamber (1-5).When pressure pulse after elongated spiral damping line arrives cushion chamber (1-5), one step ground, a step ground is disappeared to be cut, and is sent to have become on the pressure gauge component steadily, so can make the tensimeter indication steady, improves serviceable life simultaneously.
Embodiment two: the direct-type vibration abatement for pressure gauge.
Present embodiment cooperates double-screw bolt (2-4) by packing in the pressure tapping (2-1), also forms one section spiral damping line after cooperating interior spiral shell (2-2) and cooperating double-screw bolt (2-4) to cooperate.Cooperate on the double-screw bolt (2-4) and also have cushion chamber.Pressure tapping (2-1) has system's connecting portion and system's body (2-3) to fuse.Its disappear cut pressure pulse principle with embodiment one.
For the vibration abatement for pressure gauge of producing according to this design and traditional vibration abatement for pressure gauge, the applicant does the contrast in serviceable life on hydraulic gate, and tensimeter improves serviceable life greatly as a result, improves 100 times at least.
Claims (2)
1, a kind of vibration abatement for pressure gauge, fittings body have system's connecting portion to be connected with the system body, and pack into successively from the top of fittings body keeper, tensimeter is characterized in that: fittings body have cooperate in spiral shell with cooperate the double-screw bolt cooperation, form one section spiral damping line; Cooperate on the double-screw bolt and have cushion chamber.
2, vibration abatement for pressure gauge according to claim 1, pressure tapping and system's body fuse, and it is characterized in that: pressure tapping replaces fittings body, cooperates double-screw bolt to be arranged in the pressure tapping.
