Abstract
A glass float flowmeter comprises an upper sealing end installed on an installation base plate, a lower sealing end, and a glass tube installed between the upper sealing end and the lower sealing end. The upper sealing end is provided with an exhaust nozzle. The lower sealing end is provided with an intake nozzle and further provided with an air flow regulation device. The glass tube is sealed in the radial direction through a sealing device arranged in the upper sealing end and a sealing device arranged in the lower sealing end. Each sealing device comprises an installation base, an O-shaped sealing ring, a pressing ring and a pressing nut. Grooves matched with the glass tube in size are formed in the connecting ends of the installation bases and the glass tube. The glass tube is sleeved with the O-shaped sealing rings and the pressing rings in sequence and is then installed in the grooves synchronously. The glass tube is further sleeved with the pressing nuts. The inner diameter of each pressing nut is smaller than the outer diameter of each pressing ring. Each pressing nut is provided with threads to be screwed onto the corresponding installation base. According to the outer-diameter sealing structure of the glass tube, the glass tube is sleeved with the standard O-shaped sealing rings and the O-shaped sealing rings are pressed by the threaded pressing rings to achieve sealing, and therefore adverse factors caused by end face sealing of the glass tube are avoided.
Description
Technical field
The utility model relates to a kind of glass ball float flowmeter.
Background technology
Current glass tube suspended body flowmeter, is mainly made up of ball float (or rotor), glass tube, glass tube seal head and adjusting knob etc.Existing suspended body flowmeter is structurally: 1. glass tube sealing generally adopts rubber seal glass tube upper and lower end face, belongs to butt-end packing, and due to glass tube two ends otch injustice, burr causes poorly sealed reality, causes flowmeter easily to leak gas, and reveals vacuum; 2. upper-lower seal termination only has one end can compress adjusting, causes and compresses end sealing reliably, and other end sealing is not good enough.Thereby affecting it applies in vacuum line or high-pressure gas pipeline.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure for the deficiencies in the prior art, and good sealing effect, O-ring seal are changed glass ball float flowmeter easily.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of glass ball float flowmeter, comprise the upper sealed end being arranged on mounting base, lower seal end and be arranged on sealed end and lower seal end between glass tube, described upper sealed end is provided with exhaust nozzle, described lower seal end is provided with admission piece, the air volume regulating device being also provided with on described lower seal end, described glass tube is by being arranged on packoff in upper sealed end and lower seal end by described glass tube radial seal, described packoff comprises mount pad, O RunddichtringO, compacting ring and clamping nut, described mount pad and described glass tube link are provided with the groove matching with described glass tube size, described glass tube is arranged in described groove after being set with successively described O RunddichtringO and described compacting ring outward simultaneously, described clamping nut is also set with on glass tube and the internal diameter of described clamping nut is less than the external diameter of described compacting ring, described clamping nut is provided with screw thread spinning on described mount pad, make described clamping nut by described compacting ring, described O RunddichtringO is pressed in the groove of described mount pad.
Owing to adopting said structure, the utlity model has following advantage:
1, adopt the sealing means of seal glass tube wall to prevent glass tube internal leakage, overcome and originally brought not poorly sealed technical matters because of glass tube end face injustice or smooth finish;
2, the upper and lower sealed end of glass tube all can regulate the pretightning force between compacting ring and O RunddichtringO and mount pad by rotatably compressing nut, realizes independent regulation glass tube and mount pad, reaches better sealing effectiveness.
3, seal element adopts standard O RunddichtringO, and it is convenient to change.
In sum, the utility model glass tube external diameter hermetically-sealed construction, adopts standard O type snare outside glass tube, compresses by screw thread compacting ring, realizes sealing, has overcome the unfavorable factor that glass tube butt-end packing brings.
