Description
Technical field
The present invention specifically refers to a kind of underground engineering self-adaptive pressure controller.
Background technique
Along with developing rapidly of China's economy, land resources is day by day rare, and people get more and more to the utilization of the underground space.The structure floating accident because water buoyancy causes is there is in a lot of underground engineering when construction period meets rainy season.The floating height of each Engineering Accident is not from tens millimeters to hundreds of millimeter etc., the appearance damage all in various degree of the agent structure components such as its part beam, plate, post, wall, severe patient shows the phenomenon of frame column capital, the crushing of concrete of suspension column, part main muscle lateral deflection external drum.Basement water-proof function also damages because of floating accident simultaneously, causes basement appearance percolating water phenomenon in various degree.This type of accident causes the even bad social influence of larger economic loss, and the quantity that such engineering accident occurs is in rising trend in recent years.In order to solve the anti-floating problem of the engineering that has an accident, claimant has invented the draining pressure release scheme of basement before this, and be applied on actual engineering, but in the process of this technology being summarized to research, find that the technological scheme used at present exists certain limitation in the process of application.Applicants have invented a kind of valve subsequently and applied for patent, patent name is: a kind of underground engineering water buoyancy autocontrol valve, the patent No. is ZL201420486718.1.But, in the debugging and experimentation in later stage, claimant finds that it also exists certain defect: by elastic force apparatus to control the cracking pressure of this valve, namely this autocontrol valve adjusts cracking pressure by Regulation spring, technical requirements is high, and elastic force coverage area is mainly 0.03Mpa ~ 0.1Mpa; After a certain period of use time, its elastic force can change elastic force apparatus, needs often its elastic force of adjustment, and to obtain higher sensitivity, the adjustment workload of spring is large, is easy to occur nonstandard problem.
Summary of the invention
The object of the present invention is to provide a kind of underground engineering self-adaptive pressure controller, solve the frequent adjustment that current basement floating valve exists, the problem that workload is large, conciliation difficulty is large, reach the object accurately controlling the opening and closing of basement floating valve.
Object of the present invention is achieved through the following technical solutions:
A kind of underground engineering self-adaptive pressure controller, comprise the valve seat be connected on relief pipeline, the sidewall of valve seat offers water outlet, a step-like structure is provided with inside valve seat, step-like structure is provided with spool lining, valve seat is provided with supporting base, a valve rod along the axis movement of supporting base is installed in supporting base, valve stem end in supporting base is provided with the piston matched with spool lining, and the end passing supporting base at valve rod is provided with weights.Claimant is in the experimentation controlled original floating valve, find that As time goes on its validity controlled can reduce, after adjustment, precision is better, but also can as time goes by and precision reduce, claimant has carried out analyzing and finding according to this phenomenon: the elastic force due to elastic body is that spring gives, and spring in use, owing to being in non-free state for a long time, therefore, its elasticity coefficient can change, along with the change of elasticity coefficient, originally the elastic force of applying can change, thus the force value causing valve opening to be closed change, in order to address this problem, claimant does experiment repeatedly and theory analysis, finally propose and solve this problem with this programme: by the setting of weights, applied pressure can be learnt exactly, when the weight of weights is constant, the pressure passing to piston end surface is certain, when namely reaching certain numerical value from the pressure below valve seat, piston can be promoted upwards, by the water in relief pipeline by the interval between piston and spool lining, osculum flows out, when pressure reduces, the weight-driven piston of weights moves down, thus realize cut-off pressure release, in use, weights makes the pressure of restriction constant, thus improve the precision of stability and control.
In described valve seat, step is placed with packing ring, inside valve seat, be provided with a circle groove, be provided with lower snap ring in groove, spool lining is placed between lower snap ring and packing ring.By arranging lower snap ring and groove, can so that dismounting, the setting of packing ring has good protective action for spool lining.
Described spool lining and piston are cone match.Adopt the airtight performance between the piston of cone match and spool lining better.
Be provided with in described supporting base a bulge loop passed by valve rod and on snap ring, between bulge loop and upper snap ring, linear bearing is installed.By arranging linear bearing, can guide and keep the rectilinear movement of valve rod, can so that the dismounting maintaining of linear bearing by bulge loop and upper snap ring.
Described valve rod is also set with the outside framework oil seal laid respectively at above snap ring, below bulge loop.By arranging outside framework oil seal, the performance of linear bearing can be kept, while avoiding leakage of oil, maintaining effective operation of bearing.
Be provided with a vertical rod at the top of described valve rod, weights is sleeved in vertical rod.By arranging vertical rod, weights can increase and decrease in right amount, to meet different hydraulic pressure, pressure release needs without environment, keeps more suitable basement pressure environment.
The present invention compared with prior art, has following advantage and beneficial effect:
A kind of underground engineering self-adaptive pressure of 1 the present invention controller, by the setting of weights, applied pressure can be learnt exactly, when the weight of weights is constant, the pressure passing to piston end surface is certain, when namely reaching certain numerical value from the pressure below valve seat, piston can be promoted upwards, by the water in relief pipeline by the interval between piston and spool lining, osculum flows out, when pressure reduces, the weight-driven piston of weights moves down, thus realize cut-off pressure release, in use, weights makes the pressure of restriction constant, thus improve the precision of stability and control,
A kind of underground engineering self-adaptive pressure of 2 the present invention controller, by arranging outside framework oil seal, can keep the performance of linear bearing, while avoiding leakage of oil, maintaining effective operation of bearing;
A kind of underground engineering self-adaptive pressure of 3 the present invention controllers, by arranging vertical rod, weights can increase and decrease in right amount, to meet different hydraulic pressure, pressure release needs without environment, keeps more suitable basement pressure environment.
