Abstract
The utility model relates to an automatic compensation one-way floating ball valve, which comprises a left valve body, a right valve body, valve seats, a valve stem and a ball. The left valve body and the right valve body are mounted coaxially; the valve stem is mounted on the right valve body; the ball is fixedly mounted at the lower end of the valve stem between the left valve body and the right valve body; the valve seats are mounted at both joint positions of the ball with the left valve body and the right valve body; the left valve body is in a medium inflow direction; the left valve body and the right valve body are mounted by a spigot and sealed by an O-shaped ring; and a disk spring is mounted between the left valve body and the corresponding valve seat. The floating ball valve is simple in structure, scientific in design, reliable in sealing performance and long in service life, and is widely used for various occasions.
Description
Technical field
The utility model belongs to the valve class, the unidirectional floating ball valve of especially a kind of automatic compensation.
Background technique
Ball valve is divided into floating ball type and fixing two kinds of structures of ball-type, and wherein fixedly the structure torque of ball-type is little, and the valve seat distortion is little, and sealability is stable, and long service life is applicable to the high-pressure large-caliber occasion, but its production process complexity, the manufacture cost height.Though the floating ball type structure the most approaching with the application has characteristics simple in structure, easily manufactured, with low cost, reliable operation, but there is following defective: 1, with the pad that adjusts of the sealing gasket between the left and right valve body of valve, control pretightening force by the assembly crewman, the phenomenon of pine when tight during appearance makes the low pressure seal performance of valve can not get ensureing; 2, after using for a long time and depositing, cold deformation appears in the valve seat of fluoroplastic, causes valve not seal; 3, there is the gap between the left and right valve body of ball valve, when valve installation consequence is subjected to pipeline load (as stretching, bending), causes ball valve seepage to occur easily at the pad place of left and right valve body.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of automatic compensation unidirectional floating ball valve, this ball valve sealing reliable performance, long service life.
The purpose of this utility model is achieved in that
The unidirectional floating ball valve of a kind of automatic compensation, comprise left valve barrel, right valve barrel, valve seat, valve rod and spheroid, left valve barrel and the coaxial installation of right valve barrel, valve rod is installed on the right valve barrel, valve rod underpart between left valve barrel and right valve barrel installs spheroid, the junction of this spheroid and left valve barrel and right valve barrel all is equipped with valve seat, left valve barrel is the MEDIA FLOW Inbound, it is characterized in that: install and the employing seal with O ring by seam between described left valve barrel, the right valve barrel, a dish-shaped spring is installed between left valve barrel and valve seat.
And, a steel pad is installed between described valve seat and the belleville spring.
Advantage of the present utility model and good effect are:
1, between the left and right valve body of this ball valve by seal with O ring, improved sealability, and left and right valve body junction surface fits closely, eliminated the seepage that ball valve that the pipeline load caused occurs at left and right valve body junction surface place.
2, this ball valve has a steel pad and a dish-shaped spring is set at its back side at the valve seat back side of left valve barrel, guaranteed that valve has a stable initial sealing pressure all the time, also can compensate valve after using for a long time and depositing, the cold deformation amount that the valve seat of fluoroplastic occurs guarantees the sealing of valve.
3, this ball-valve structure is simple, design science, and sealability is reliable, and life of valve is long, is widely used in various occasions.
Description of drawings
Fig. 1 is a cross section structure sectional view of the present utility model.
Embodiment
1 couple of embodiment of the present utility model is further described below in conjunction with accompanying drawing, need to prove: present embodiment is descriptive, is not determinate, can not limit protection domain of the present utility model with this.
The unidirectional floating ball valve of a kind of automatic compensation, comprise left valve barrel 8, right valve barrel 5, valve seat 4, valve rod 2 and spheroid 3, left valve barrel is with the coaxial installation of right valve barrel and pass through double-screw bolt 7, nut 6 is fastening, valve rod is installed on the right valve barrel, valve rod underpart between left valve barrel and right valve barrel installs spheroid, the junction of this spheroid and left valve barrel and right valve barrel all is equipped with valve seat, and left valve barrel is the MEDIA FLOW Inbound.
Innovative point of the present utility model is:
Install and 1 sealing of employing O shape circle by seam between left valve barrel, the right valve barrel, adopt double-screw bolt, nut that left and right sides valve body is connected again, it is tight that junction surface is fitted.At the valve seat back side of left valve barrel one steel pad 10 is installed, a dish-shaped spring 9 also is installed between this steel pad and left valve barrel, can make valve that a stable initial sealing pressure is arranged all the time by belleville spring.
Claims (2)
1. one kind compensates unidirectional floating ball valve automatically, comprise left valve barrel, right valve barrel, valve seat, valve rod and spheroid, left valve barrel and the coaxial installation of right valve barrel, valve rod is installed on the right valve barrel, valve rod underpart between left valve barrel and right valve barrel installs spheroid, the junction of this spheroid and left valve barrel and right valve barrel all is equipped with valve seat, left valve barrel is the MEDIA FLOW Inbound, it is characterized in that: install and the employing seal with O ring by seam between described left valve barrel, the right valve barrel, a dish-shaped spring is installed between left valve barrel and valve seat.
2. the unidirectional floating ball valve of automatic compensation according to claim 1 is characterized in that: a steel pad is installed between described valve seat and the belleville spring.
