Description
Technical field
The utility model is related to a kind of balanced valve, more particularly to a kind of self-operated type balanced inlet air valve.
Background technology
Balanced valve is a kind of valve of specific function, and valve without special character, is only have using function and place in itself
Difference.In certain industries, due to medium (all kinds of flowable materials), in the various pieces of pipeline or container, there are larger
Pressure differential or difference in flow to reduce or balancing the difference, valve are installed between corresponding pipeline or container, to adjust both sides
The relative equilibrium of pressure or the balance for reaching flow by the method for shunting, the valve are just balanced valve.But existing market
Upper most of balanced valve functionality is all relatively simple, uses also very inconvenient, traditional balanced valve due to spool material
Commonly, using after when one section, situation about being corroded is susceptible to, thereby using short life, it is impossible to suitable for oil, chemical industry,
Metallurgy, light textile, military project, medicine and deep-sea aquatic products support the fields such as plant, and traditional balanced valve single can only make as balanced valve
With two position three way directional control valve and triple valve can not being used as to use, and balancing speed is slower.For this purpose, it is proposed that one kind is relied on oneself
Formula balanced inlet air valve.
Utility model content
The main purpose of the utility model is that providing a kind of self-operated type balanced inlet air valve, the utility model is due to spool
The spool of drum structure,, can since spool is process using resistant material so as to so that the balancing speed of balanced valve is fast
To reduce spool corrosion resistant degree of corrosion, so as to improve the service life of balanced valve, can be widely applied to oil, chemical industry, metallurgy,
Light textile, military project, medicine and other fields support plant especially suitable for deep-sea aquatic products, and practicability and applicability have obtained significant increase, simultaneously
The features such as also there is structure novel, small, light-weight, high sensitivity, long lifespan, can work without control, and can a valve
It is multi-purpose, it is suitble to produce use in enormous quantities, can effectively solves the problems in background technology.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of self-operated type balanced inlet air valve, including valve body and spool, the spool is located at valve inner, between the spool
Sealing ring is provided with, the sealing ring upper end is provided with output channel, and described spool one end is provided with spring, the spring one end
Input channel and adjustment nut are provided with, the adjustment nut is located at input channel outer wall surrounding.
Further, the input channel and output channel are T-type structure.
Further, the spool is the spool of drum structure.
Further, the spool is connect with valve body slides.
Further, the spool is process using resistant material.
Compared with prior art, the utility model has the advantages that：
1st, the utility model is due to the spool that spool is drum structure, and when valve pressurizes, the gas inputted from air inlet divides
It is not inputted simultaneously by two input channels, flows to intermediate output channel, when two input channel pressure changes generate pressure difference,
I-shaped spool by high pressure end pressure effect to low pressure end movement, reduce the input port sectional area of high-pressure side, increase low
The input port sectional area of pressure side so as to accelerate the air inflow of low-pressure end, accelerates the input of medium, and when both sides, pressure is identical
When, since the pressure on both sides is equal, I-shaped spool displacement is allowed to, reaches new balance, spool returns to centre position again,
So as to so that the balancing speed of balanced valve is fast.
2nd, the utility model is process using resistant material due to spool, can reduce spool corrosion resistant degree of corrosion, from
And the service life of balanced valve can be improved, and oil, chemical industry, metallurgy, light textile, military project, medicine and other fields are can be widely applied to, it is special
Not Shi Yongyu deep-sea aquatic products support plant, practicability and applicability have obtained significant increase.
3rd, the utility model also has structure novel, small, light-weight, high sensitivity, long lifespan simultaneously, without control
The features such as can working, and can multi-purpose valve, be suitble to produce in enormous quantities use.

Fig. 1 is a kind of overall structure diagram of self-operated type balanced inlet air valve of the utility model.
In figure：1st, valve body；2nd, sealing ring；3rd, input channel；4th, nut is adjusted；5th, output channel；6th, spool；7th, spring.
Specific embodiment
To be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, below
With reference to specific embodiment, the utility model is expanded on further.
As shown in Figure 1, a kind of self-operated type balanced inlet air valve, including valve body 1 and spool 6, the spool 6 is located in valve body 1
Portion is provided with sealing ring 2 between the spool 6, and 2 upper end of sealing ring is provided with output channel 5, and described 6 one end of spool is set
Spring 7 is equipped with, described 7 one end of spring is provided with input channel 3 and adjustment nut 4, and the adjustment nut 4 is located at input channel 3
Outer wall surrounding.
Wherein, the input channel 3 and output channel 5 are T-type structure.
Wherein, the spool 6 is the spool of drum structure.
Wherein, the spool 6 is slidably connected with valve body 1.
Wherein, the spool 6 is process using resistant material.
It should be noted that the utility model is a kind of self-operated type balanced inlet air valve, during work, bullet is leaned in the position of spool 6
Spring 7 is fixed, and fine tuning is realized by adjusting nut 4.When valve no pressure, due to the effect of spring 7, I-shaped spool 6 begins
In an intermediate position eventually, the aisle spare for making its both sides is equal.When valve pressurizes, the gas inputted from air inlet is respectively by two
Input channel 3 inputs simultaneously, flows to intermediate output channel 5, when two 3 pressure changes of input channel generate pressure difference, I-shaped
Type spool 6 by high pressure end pressure effect to low pressure end movement, reduce the input port sectional area of high-pressure side, increase low-pressure end
Input port sectional area, so as to accelerate the air inflow of low-pressure end, accelerate the input of medium, when both sides pressure is identical, by
Pressure in both sides is equal, is allowed to I-shaped 6 displacement of spool, reaches new balance, spool 6 returns to centre position again.And
Two position three way directional control valve can be used as, triple valve uses.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
