Description
Technical field
The utility model belongs to ball-and-seat technical field, in particular it relates to a kind of adjustable ball-and-seat valve of pressure limit
Core.
Background technology
Ball-and-seat refers to a kind of open and close flap automatic by fluid media (medium) flowing in itself, only allows fluid media (medium) list
To the valve of flowing.Fluid media (medium) can only flow into along entrance, outlet outflow, and can not be from outlet return, and it is mainly used in anti-
The occasion that only fluid media (medium) flows backwards.A kind of conventional ball-and-seat is gravity type ball-and-seat, and valve element is seated on valve seat, below valve seat
For entrance, valve seat top is outlet.Its operation principle is, if fluid media (medium) flows into valve body by entrance, overcomes valve element by pressure
Self gravitation, valve element is from bottom to top jacked up, realize conducting；If fluid media (medium) flows into valve body by outlet, by pressure and valve element
Self gravitation, from top to bottom valve element is depressed, realize closing.
At present, ball-and-seat manufacturer is fixed to the design work pressure limit of dispatching from the factory of valve element.And in ball-and-seat
In oil-gas field development application field, because gas production field is bigger in the ductwork pressure fluctuation of different production phases；For example, in gas
Field producing initial stage, gas well pressure is larger, and with the progress of production, gas well pressure is often in the trend being gradually reduced.Work as upstream and downstream
Pressure change dispatch from the factory design work pressure limit when, ball-and-seat cannot carry out normal work.Specifically, when upstream is pressed
Power is decreased to overcome downstream pressure with valve element self gravitation when making a concerted effort, and ball-and-seat then can not be normally-open, realizes conducting
Pipe network.Thereby result in pipe network can not normal continuous conveying natural gas, have a strong impact on the normal production of upstream, and downstream user
Accurate metering.
Utility model content
The purpose of this utility model is：The problem of fixed be present for the working pressure range of prior art valve element, carry
For a kind of adjustable single current valve core of pressure limit, the valve element can be adjusted according to gas well pressure to required operating pressure model
Enclose.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of adjustable single current valve core of pressure limit, including guide rod and the valve for being arranged on the guiding boom end
Valve, in addition to the weight stack being detachably connected on the flap.Weight stack is set on the flap, makes the weight of valve element
It is adjustable, and then can adjust the working pressure range of valve element.
Preferably, the weight stack is arranged at the side of remote valve seat, and the weight stack is ring-type.Due to being oriented to
The top of bar is bonnet, and guide rod slides in the guide cylinder of bonnet.The weight stack is ring-type, and it is hollow bulb that it is internal, no
Weight stack is caused to be interfered with the guide cylinder, so as to influence the opening and closing degree of flap.In addition, this design do not change it is original
On the basis of valve core structure, the valve element can be individually replaced on existing ball-and-seat, it is economical and practical.
Preferably, the side of the remote valve seat of the flap is provided with screw, be provided with the weight stack with it is described
The mounting hole that screw matches, the mounting hole of a bolt through the weight stack is connected with the screw.Bolt, which is fixed, to be caused
It is convenient to change, and reduces maintenance cost, need to such as install multiple weight stacks additional, need to only use stay bolt, operation still fast and easy.
Preferably, the flap is made up of Q460 steel, meets single current valve core under operating pressure, constantly by
To the intensity requirement of impact wear.
Preferably, the side of the nearly valve seat of the flap is provided with cushion pad, and the cushion pad is engaged with valve seat.
Cushion pad contacts with valve seat, can effective noise reduction, reduce the impact wear between metal, increase the service life, can also prevent
Spark is only produced, improves security performance.
Preferably, the cushion pad is made up of wear-resisting, acidproof, alkaline-resisting and corrosion resistant rubber.Rubber is can
While ensureing buffering effect, its cost is cheap, and production is simple.
Preferably, in addition to pressing plate, the side of the nearly valve seat of flap are provided with screw, the cushion pad and pressure
Plate is provided with the mounting hole to match with the screw, by the mounting hole and institute of pressing plate described in a screw bolt passes and cushion pad
State screw connection.Pressing plate may be configured as different thickness, further widen the adjustment of weight scope of valve element.In addition, as buffered
Pad damage, bolt, which is fixed, make it that replacing is convenient, reduces maintenance cost.
In summary, by adopting the above-described technical solution, compared to prior art, the beneficial effects of the utility model
It is：
1st, the valve element can be adjusted according to gas well pressure to required working pressure range, to meet the production of whole gas well week
Phase.At gas well liquid loading initial stage, pressure is larger, must install several weight stacks additional.With the progress of production, gas well pressure is under
Drop, then need to gradually decrease the number of weight stack as needed.Until gas well liquid loading latter stage, pressure is smaller, need to be by all counterweights
Piece disassembles, and mitigates valve element overall weight.Further, it is also possible to add the pressing plate of different-thickness, work pressure has further been widened
The adjustable extent of power.
2nd, the valve element contacts existing flap with the metallic hard of valve seat, has been changed to the rubber and metal of cushion pad and valve seat
Soft contact, so as to effective noise reduction, reduce the impact wear between metal, increase the service life, be also prevented from producing
Spark, improve security performance.
