Abstract
The utility model relates to a kind of valve seat construction of hard seal floating ball valve, draw together valve body, valve seat insert, valve seat and spheroid, valve seat is shaped with endoporus, spheroid and valve seat are coaxially arranged in mounting groove made in valve body, between valve body and valve seat, radial direction is coaxially installed with a valve seat insert, between valve seat and valve seat insert, axial order is provided with belleville spring and pressure ring, and valve seat cylindrical is provided with dust ring.The utility model is provided with spring dust guard, has stopped impurity and spring contact, prevents disc spring stuck, extends the service time of disc spring; Valve seat insert adopts rhombus, and sealability is more reliable.
Description
Technical field
The utility model belongs to valve field, especially a kind of valve seat construction of hard seal floating ball valve.
Background technique
At present, the prior art valve seat back side does not have preloading spring or adopts cylinder cylindrical spring, and valve seat insert adopts rectangle, poor sealing performance.Cylinder cylindrical spring place easily accumulates impurity, may cause stuck spring; Valve seat insert adopts rectangle, and poor sealing performance, working life is short.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of valve seat construction of hard seal floating ball valve, solves valve seal poor performance, extends spring service time, increases life of valve.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of valve seat construction of hard seal floating ball valve, draw together valve body, valve seat insert, valve seat and spheroid, valve seat is shaped with endoporus, spheroid and valve seat are coaxially arranged in mounting groove made in valve body, between valve body and valve seat, radial direction is coaxially installed with a valve seat insert, it is characterized in that: between valve seat and valve seat insert, axial order is provided with belleville spring and pressure ring, valve seat cylindrical is provided with dust ring.
And described valve base sealing ring cross-section is rhombus.
Advantage of the present utility model and good effect are:
The utility model is provided with spring dust guard, has stopped impurity and spring contact, prevents disc spring stuck, extends the service time of disc spring; Valve seat insert adopts rhombus, and sealability is more reliable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of valve seat construction of hard seal floating ball valve, comprise valve body 1, valve seat insert 2, valve seat 6 and spheroid 7, valve seat is shaped with endoporus, as shown in Figure 1, spheroid and valve seat are coaxially arranged in mounting groove made in valve body, and between valve body and valve seat, radial direction is coaxially installed with a valve seat insert, spheroid contacts with valve seat, under pretightening force effect, play sealing effect, the sealing of valve body and valve seat is realized by valve seat insert.
Innovative point of the present utility model is:
Ensure sealing effect to strengthen sealed ring deformation amount, valve base sealing ring cross-section is rhombus; Between valve seat and valve seat insert, axial order is provided with belleville spring 4 and pressure ring 3, and belleville spring has certain decrement, produces elastic force, pressure ring and valve seat insert is compressed.
Valve seat cylindrical is provided with dust ring 5, and valve seat cylindrical is equipped with dust ring, has stopped impurity and spring contact, prevents disc spring stuck, extends the service time of disc spring.
