Abstract
The utility model discloses a floating ball and mandril type tank truck liquid level control triggering device, and mainly solves the problems of low vibration resistance, short service life and low safety of the conventional liquid level controller for an oil-water tank truck. The floating ball and mandril type tank truck liquid level control triggering device is characterized in that a swing rod seat is fixed on the upper side of a flange cover on the upper part of a tank truck; a sealing barrel is fixed on the lower side of the flange cover; two nylon sealing rings are fixed in the sealing barrel along the axial direction; a vertical type mandril is fixed in the sealing barrel in a sliding connection manner and limited between the two nylon sealing rings; a floating ball is fixed at the lower end of the vertical type mandril; the upper end of the vertical type mandril passes through a precast hole through a pin shaft and is hinged with a hole in a horizontal swing rod; the middle section of the horizontal swing rod is hinged to the swing rod seat; the other end of the horizontal swing rod is connected with a balance block; and a rod body of the horizontal swing rod, which is positioned between the swing rod seat and the vertical type mandril is contacted with a travel switch. The triggering device is long in service life and good in safety anti-explosion effect and can bear drastic bump of the tank truck during traveling.
Description
Technical field
The utility model relates to a kind of tank car liquid level control flip flop equipment that is used on the oil field shipment profit tank car.
Background technology
The tank car of oil field shipment profit need be controlled liquid level when injecting crude oil or oil-water mixture, warning and by-pass valve control are closed when the arrival regulation liquid level upper limit, to avoid jar danger of overflowing.The fluid level control device that is used for the profit tank car at present mainly contains mechanical type or electromagnetism float-type liquid level controller, utilizes the liquid buoyancy that arrives the standard solution position to trigger the control corresponding switch through mechanical drive or electromagnetic induction, realizes reporting to the police and control interlock function.Though these control setups have been employed for many years; But; But existing following problem never solves: after conventional machinery or electromagnetism ball float level controller are loaded onto the profit tank car; Because crude oil and sewage viscosity are big and the severe jolt of vehicle ' process, cause the malfunctioning or damage parts of liquid level control switch easily.And the trigger switch of fluid level controller contacts with corrosive property oil gas, and long-time use can cause the explosive-proof sealed partial failure of trigger switch, if untimely replacing then very easily fires danger.Therefore, conventional mechanical or electromagnetism ball float level controller life-span that oil rail tanker is installed are very short, need frequent change.
Summary of the invention
In order to solve the prior art problem that provides in the background technology, the utility model provides a kind of ball float post rod type tank car liquid level control flip flop equipment, and this kind installs long service life, can bear the severe jolt of tank car driving process, and safety anti-explosive is effective.
The technical scheme of the utility model is: this kind ball float post rod type tank car liquid level control flip flop equipment comprises ball float, sealed chamber, blind flange, has vertical push rod, travel switch, horizontal fork, swing rod and the balance block of some pre-manufactured holes on the top; Wherein, swing rod is fixed on the upside of blind flange, and sealed chamber is fixed on the downside of blind flange; Be fixed with twice sealed nylon ring in the said sealed chamber vertically, vertical push rod is fixed in the sealed chamber with the sliding block joint mode, is limited between the said twice sealed nylon ring; The lower end of said vertical push rod is ball float fixedly, its upper end through bearing pin pass behind the pre-manufactured hole with horizontal fork on the hole hinged; The interlude of said horizontal fork is hinged on the swing rod, and the other end then is connected with balance block; Said travel switch is fixed on the upside of blind flange, and the upper body of rod between swing rod and vertical push rod of said horizontal fork touches with travel switch mutually.
During concrete the realization, said blind flange, sealed chamber, horizontal fork, swing rod and balance block all preferably adopt the carbon steel manufacturing, and said vertical push rod and ball float all preferably adopt the corrosion-resistant steel manufacturing.
The utlity model has following beneficial effect: this kind device adopts vertical push rod buoyancy transmission device, and its anti-vibration intensity can be born the severe jolt of tank car driving process far above horizontal cantilever beam buoyancy transmission device, thereby long service life.In addition, travel switch is arranged into tank body outside, through push rod and fork link gear transmission buoyancy, electrical equipment not with jar in medium contact, therefore, explosion-proof effect is good.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
1-ball float among the figure, 2-sealed chamber, 3-blind flange, the vertical push rod of 4-, 5-travel switch, the horizontal fork of 6-, 7-swing rod, 8-balance block.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1, this kind ball float post rod type tank car liquid level control flip flop equipment comprises ball float 1, sealed chamber 2, blind flange 3, has vertical push rod 4, travel switch 5, horizontal fork 6, swing rod 7 and the balance block 8 of some pre-manufactured holes on the top.Wherein, swing rod 7 is fixed on the upside of blind flange 3, and sealed chamber 2 is fixed on the downside of blind flange 3; Be fixed with twice sealed nylon ring in the said sealed chamber 2 vertically, vertical push rod 4 is fixed in the sealed chamber 2 with the sliding block joint mode, is limited between the said twice sealed nylon ring; The lower end of said vertical push rod 4 is ball float 1 fixedly, its upper end through bearing pin pass behind the pre-manufactured hole with horizontal fork 6 on the hole hinged; The interlude of said horizontal fork 6 is hinged on the swing rod 7, and the other end then is connected with balance block 8, to offset push rod and ball float gravity, increases buoyancy effects.Said travel switch 5 is fixed on the upside of blind flange 3; The body of rod on the said horizontal fork 6 between swing rod 7 and vertical push rod 4 touches with travel switch 5 mutually, and like this, fork is swung on swing rod; Can arrive the travel switch contact above it by roof pressure, to realize corresponding triggering control.
With said modules connect finish after, the corrosion-resistant steel push rod of vertical installation can slide in the carbon steel sealed chamber, because the sealing of twice nylon ring is arranged in the sealed chamber, therefore can prevent that oil gas overflows in the jar, simultaneously the also slide rail of double as push rod of nylon ring.
Be to improve resistance to corrosion, enterprising one-step optimization does on above scheme basis, and said blind flange 3, sealed chamber 2, horizontal fork 6, swing rod 7 and balance block 8 all adopt the carbon steel material manufacturing, and said vertical push rod 4 is stainless steel material with ball float 1.
During use, ball float post rod type tank car liquid level control flip flop equipment utilizes its simple steel flange lid to be installed on the horizontal tank body upper flange hole of tank car, comes the adjusting control electrolyte level through different hinge holes position on the push rod.Oil rail tanker injects crude oil or oil-water mixture operation process; When tank level rises near the regulation liquid level upper limit; Liquid contacts with ball float, and ball float and push rod also rise thereupon, drives the travel switch contact of fork roof pressure above it; Switch circuit triggers, and connects corresponding the warning and control system.
This kind of ball float post rod type tank car liquid level control flip flop equipment adopts upright push rod to add horizontal pendulum rod-type buoyancy and transmits form, and through the fork arm of force ball float roof pressure power is increased, and jolts with anti-with the reliable trigger that realizes mechanism.
