Abstract
The utility model relates to a multifunctional throttle cut-off emptying valve. The multifunctional throttle cut-off emptying valve comprises a valve body, a valve seat, a plunger piston, a plunger piston sleeve, a valve cap and a valve rod, wherein the lower end of the plunger piston is connected with a sealing seat, sealing rings are arranged between the plunger piston and the sealing seat and in the closing position of the valve seat, and the closing position of the sealing seat and the valve seat is provided with a conical surface. The utility model has the advantages that the condition that media directly flush sealing surfaces is avoided, and the sealing reliability and the service life of the product are improved. The utility model has the advantages of noise reduction, shock absorption, etc.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of multi-functional throttling by atmospheric valve.
Background technique
Existing stop valve, because its structural imperfection, medium forms directly sealing surface and washes away, and has reduced the sealing reliability and the working life of product.
Summary of the invention
The utility model provides the multi-functional throttling of a kind of sealing reliability height, long service life by atmospheric valve, it is achieved through the following technical solutions: a kind of multi-functional throttling is by atmospheric valve, comprise valve body, valve seat, plunger, plunger bushing, valve gap and valve rod, lower end at plunger is connected with sealing seat, be provided with seal ring between plunger and sealing seat and with the closure place of valve seat, the closure place of sealing seat and valve seat is the conical surface.
In valve gap, be provided with the plunger guide cover, between plunger bushing and plunger guide cover, be provided with the plunger seal circle.The cross section of described plunger seal circle is " X " shape.Described plunger bushing is detachable.
The utility model has the advantages that: avoided medium to directly the washing away of sealing surface, improved the sealing reliability and the working life of product, and have advantages such as noise reduction, damping.
Description of drawings
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
A kind of multi-functional throttling is by atmospheric valve, comprise valve body 1, valve seat 2, plunger 5, plunger bushing 6, valve gap 9 and valve rod 12, be connected with sealing seat 3 in the lower end of plunger 5, be provided with seal ring 4 between plunger 5 and sealing seat 3 and with the closure place of valve seat 2, sealing seat 3 is the conical surface with the closure place of valve seat 2.The sealing structure is an inner cone sealing strip soft seal supplementary structure, the sealing surface place does not accumulate the impurity in the medium, has avoided medium to directly the washing away of sealing surface, thus the sealing reliability and the working life of having improved product.
In valve gap 9, be provided with plunger guide cover 8, between plunger bushing 6 and plunger guide cover 8, be provided with plunger seal circle 7.The cross section of described plunger seal circle 7 is " X " shape.The interference fit that the plunger seal abutment surface produces between the seal ring that the steel plunger and the soft sealing material of corrosion-proof wear processing are made forms, the plunger seal specific pressure can be regulated with middle mouthful of double-screw bolt 11, the nut 10 of valve gap 9, can guarantee the reliability that seals at any time.
Described plunger bushing 6 is detachable.As long as change different plunger bushings 6, the requirement that this valve just can satisfy the anti-low noise that cavitates, throttling, end reaches multi-purpose valve.
