Abstract

The utility model relates to the technical field of valves and provides a novel dome valve. A driven shaft (2) is arranged in a valve body (1), a top plate (3) is arranged at the upper end of the valve body (1), an expandable seal ring (4) is arranged in the top plate (3), a domed valve disc (5) is arranged in the middle of the valve body (1), the driven shaft (2) is connected with a driving shaft (6), an approach switch (7) is arranged on one side of the valve body (1), one end of the valve body (1) is connected with a double-acting cylinder (8), and an outlet connector (9) is arranged at the lower end of the valve body (1). The novel dome valve is compact in structure, convenient to use, small in size, light in weight, good in sealing effect, long in service life, suitable for the treatment of dusty gas and erosive material in bulk and wide in application range, and has abrasion and corrosion resistant.

Description

A kind of novel dome valve
Technical field:
The utility model relates to valve technology field, relates in particular to a kind of novel dome valve.
Background technique:
Dome valve is because the particularity of its structure, first-selected valve during normally strength is carried, dome valve can cut off mobile material stream or the static stock column that enters pressurized tank, then close and realize sealing, thereby the pack completeness that guarantees pressurized tank is 100%, and need not depend on the level-sensing device of sending cans, so control principle is simple and reliable.
Dome valve is when processing chiseling property of mill material, be embedded in the inflatable pressure sealing ring of dome valve seat, guarantee that the working pressure before and after the valve is poor, the flexible expandable seal circle material particles that can cave in, avoided because the differential pressure action material particles slides, to the wearing and tearing of valve seat and seal ring, existing dome valve structure is too simple, and volume is large, poor sealing, not wear-resisting, working life is short, and Applicable scope is extensive not.
The model utility content:
The purpose of this utility model provides a kind of novel dome valve, its compact structure, and easy to use, volume is little, lightweight, good sealing effect has wear resistant corrosion resistant, long service life is applicable to process dust-containing airflow and erosion loose unpacked material, and Applicable scope is extensive.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it by valve body 1, driven shaft 2, take over a business 3, expandable seal circle 4, vaulted flap 5, live axle 6, approach switch 7, double-acting cylinder 8, go out opening connector 9 and form; Be provided with driven shaft 2 in the valve body 1, the upper end of valve body 1 is provided with 3, take over a business and be provided with expandable seal circle 4 in 3, the middle part of valve body 1 is provided with vaulted flap 5, driven shaft 2 is connected with live axle 6, one side of valve body 1 is provided with approach switch 7, and an end of valve body 1 is connected with double-acting cylinder 8, and the lower end of valve body 1 is provided with out opening connector 9.
The shell of described valve body 1 and vaulted flap 5 adopt the spheroidal graphite cast iron material to make.
The material of described expandable seal circle 4 adopts neoprene, silicone rubber, fluorine rubber and ethylene propylene diene rubber etc.
The utility model is to rely on pressurized air to realize the tight seal effect, can be used for discharging valve, technological process valve, change-over valve, reactor valve, fluidized bed combustion chamber valve, pressurized gas reactor and the dropping equipment etc. in storehouse, storehouse.
The utility model compact structure, easy to use, volume is little, and is lightweight, and good sealing effect has wear resistant corrosion resistant, and long service life is applicable to process dust-containing airflow and erosion loose unpacked material, and Applicable scope is extensive.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A section enlarged view of Fig. 1.
Embodiment:
With reference to Fig. 1, Fig. 2, this embodiment by the following technical solutions: it by valve body 1, driven shaft 2, take over a business 3, expandable seal circle 4, vaulted flap 5, live axle 6, approach switch 7, double-acting cylinder 8, go out opening connector 9 and form; Be provided with driven shaft 2 in the valve body 1, the upper end of valve body 1 is provided with 3, take over a business and be provided with expandable seal circle 4 in 3, the middle part of valve body 1 is provided with vaulted flap 5, driven shaft 2 is connected with live axle 6, one side of valve body 1 is provided with approach switch 7, and an end of valve body 1 is connected with double-acting cylinder 8, and the lower end of valve body 1 is provided with out opening connector 9.
The shell of described valve body 1 and vaulted flap 5 all adopt the spheroidal graphite cast iron material to make.
The material of described expandable seal circle 4 adopts neoprene, silicone rubber, fluorine rubber and ethylene propylene diene rubber etc.
This embodiment is to rely on pressurized air to realize the tight seal effect, can be used for discharging valve, technological process valve, change-over valve, reactor valve, fluidized bed combustion chamber valve, pressurized gas reactor and the dropping equipment etc. in storehouse, storehouse.
This embodiment compact structure, easy to use, volume is little, and is lightweight, and good sealing effect has wear resistant corrosion resistant, and long service life is applicable to process dust-containing airflow and erosion loose unpacked material, and Applicable scope is extensive.
