Description
Technical field
The utility model belongs to machinery valve technical field, particularly relates to a kind of cryogenic ball valve valve seat construction playing unlatching or close medium effect on pipeline.
Background technique
Existing valve seat construction mainly comprises the compositions such as valve body, lip-type packing, graphite rope, helical spring, spring seat, valve seat supporting, regulating ring, valve seat, spheroid, this structure composition is complicated, processing cost is higher, assembling and dismounting difficulty larger, the lip-type packing of axially installing easily damages in installation and removal process, have impact on sealability and the maintenance efficiency of valve.
Model utility content
For above-mentioned technical problem, the utility model aims to provide a kind of structure cryogenic ball valve valve seat construction simple, easy to maintenance, and effectively can improve sealing and the reliability of cryogenic ball valve valve seat.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of cryogenic ball valve valve seat construction, mainly comprises valve body, valve seat supporting, valve seat, spheroid; Described valve seat is arranged in the groove of valve seat supporting, and valve seat supporting side coordinates with valve body, and the valve seat of opposite side coordinates with spheroid; Described valve seat supporting coordinates side to be provided with seal groove with valve body, is provided with seal ring in seal groove; The fitting surface that valve body and valve seat support is inclined-plane, forms wedge-shaped opening between inclined-plane and spherome surface, and valve seat supporting and valve seat are arranged in wedge-shaped opening.
Further, described inclined-plane becomes 1-10 ° of angles with valve longitudinal axis.
Preferably, the angle of described inclined-plane and valve longitudinal axis is 5 °.
Preferably, the fitting surface of described valve seat and spheroid is arc surface.
Further, described seal ring is Plane Installation.
Further, described seal ring is lip-type packing.
The utility model comparatively prior art is compared, and has the following advantages and beneficial effect:
1. simplify valve seat construction, reduce cost and manufacture cycle;
2. the seal ring sealed between valve seat supporting and valve body is Plane Installation, improves sealing and the working life of valve seat, also can reduce the difficulty of valve seat installation and removal, improves the efficiency that valve seat is changed;
3. sealing surface of seat is arc surface, the seal point between valve seat and spheroid can be adjusted automatically, avoid the impact of the factors such as machining error on sealing effect, improve the reliability of sealing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model in cryogenic ball valve.
In figure: the supporting of 1-valve body, 2-seal ring, 3-valve seat, 4-valve seat, 5-spheroid.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of cryogenic ball valve valve seat construction, mainly comprise valve body 1, valve seat supporting 3, valve seat 4, spheroid 5, described valve seat 4 is arranged in the groove of valve seat supporting 3, and valve seat supports 3 sides and coordinates with valve body 1, and the valve seat 4 of opposite side coordinates with spheroid 5; Described valve seat supporting 3 coordinates side to be provided with seal groove with valve body 1, is provided with seal ring 2 in seal groove; The fitting surface that valve body 1 and valve seat supports 3 is inclined-plane, forms wedge-shaped opening between inclined-plane and spheroid 5 surface, valve seat support 3 and valve seat 4 be arranged in wedge-shaped opening.Described inclined-plane becomes 1-10 ° of angles with valve longitudinal axis, and described angle is preferably 5 °.Described valve seat 4 is arc surface with the fitting surface of spheroid 5; Described seal ring 2 is Plane Installation, and described seal ring 2 is lip-type packing.
As shown in Figure 2, a complete embodiment of the present utility model, when carrying out valve seat assembling, only spheroid 5, valve seat 4, valve seat supporting 3, seal ring 2 first need be assembled into together, put into along valve body 1 inclined-plane from top, utilize wedge shape power to realize the pretension of valve seat 4 and seal ring 2, reduce the difficulty of installation and removal; Seal ring 2 adopts Plane Installation, realizes plane sealing, improves the reliability and stability of its sealing; Valve seat 4 is arc surface with the fitting surface of spheroid 5, the seal point between valve seat 4 and spheroid 5 can be adjusted automatically, avoid the impact of the factors such as machining error on sealing effect, improve the reliability of sealing.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
