Abstract
The utility model discloses an automatic exhaust control valve assembled in a water tank in the roof and is composed of an upper shell, a lower shell and a ball cock component which is connected with the top of the upper shell in a sealed manner, wherein, the ball cock component comprises a valve body, a valve plug, a piston, a connecting bar and a ball float. The utility model is characterized in that a sealing ring is embedded on the lower part of the valve plug and forms a junction surface with high leak tightness with a spherical sealing ring on the top of the piston, and the underside of the lower shell is designed to be a circular arc shape, and a water strainer is arranged at the place of a water inlet, thereby the utility model has the advantages of good sealing effect, enough air displacement and air input, and assured simultaneous water use for all users; even hydraulic pressure is up to critical hydraulic pressure, complete sealing effect can be achieved; the underside of the water tank which is of a circular arc shape has fluent water drainage; the water strainer can prevent impurities in pipelines from entering a vent valve to block air exit holes.
Description
Technical field
The utility model relates to a kind of automatic exhaust device, especially is installed in the automatic vent control valve at roof tank top.
Background technique
Outlet valve in domestic water supply, generally be applied to the to pass a bridge automatic vent of pipeline, automatic control pressure vent in " non-pollution water supply system for multi-story building " of prior art such as application number 011053496 is to realize inlet and outlet by ball float fluctuating in valve body, in use owing to only borrow ball float self buoyancy to realize sealing, the requirement ball float is light, volume is big, is difficult for sealing when critical pressure.And for example the patent No. is " automatic control pressure vent " of 99256431.X, be mounted in water-heating boiler or the tall building central heating pipe, for shortening the period of exhaust that supplies water first, increasing work efficiency and design, it comprises formations such as upper shell, lower shell body, float valve assembly, its major character is that the transverse row pore is set on valve body, quicken the gaseous emission in the cavity volume, shorten water supply time.And be arranged on outlet valve on the roof tank, except that must guarantee to have enough air displacemenies and air inflow, to guarantee that all users are simultaneously the needs of waters, also must guarantee when critical hydraulic pressure water-tight, because be installed on the dwelling house roof, hydraulic pressure is very low, for this reason, must guarantee very high sealing, to this, the automatic control pressure vent of above-mentioned patent is difficult to meet the demands.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and automatic vent control valve that a kind of high leak tightness is provided, to guarantee to have enough air displacemenies and air inflow, water is unquestionable simultaneously to guarantee all users, even hydraulic pressure is very low, outlet valve is also water-tight when critical hydraulic pressure.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the automatic vent control valve, comprise the upper shell that fixes, the lower shell body and the float valve assembly that is sealedly connected on the upper shell top that have water intake, this float valve assembly comprises the valve body of sealing and fixing at upper shell, have the transverse row pore on the valve body, be provided with spool in the valve body, spool is provided with and the extraneous pore that communicates, valve body lower portion is the piston of slippage up and down that is embedded with seal ring, the piston bottom is provided with hinged connecting rod, this interlinking lever end is connected with valve body by coupling shaft, the other end connects ball float, it is characterized in that described spool lower end is embedded with seal ring, the seal ring on it and the piston is formed the junction plane of high leak tightness.
Seal ring end face on the described piston is spherical shape.
Described spool is "+" font with the extraneous pore that communicates.
Described spool top is provided with fixing removable dust-proof cover.
Described lower shell body bottom surface is plane shape or circular arc.
Described lower shell body water inlet is provided with water strainer.
The utility model compared with prior art, set up seal ring in the spool bottom, make seal ring on itself and the piston form the sealed faying face of highly dense front cover, and the seal ring end face on the piston adopts spheric structure, make sealing effect better, when making opening of valves, assurance has enough air displacemenies and air inflow, water is unquestionable simultaneously to guarantee all users, thisly utilize lever principle to realize sealing, can reach the critical hydraulic pressure state effectively and realize the effect of sealing fully, can replace the automatic control pressure vent in 01105349 invention; Arc-shaped structure is adopted in lower shell body bottom, and when guaranteeing that water tank discharges water, the water in the outlet valve can quick drain, and ball float is fallen rapidly, and air enters from exhaust port, guarantees the water tank smoothness that discharges water; The design of outlet valve water inlet jointing has water strainer, prevents that pipeline impurity from entering outlet valve and stopping up exhaust port.
Description of drawings
Fig. 1 is the utility model closed condition structural representation.
Fig. 2 opens the status architecture schematic representation that discharges water for the utility model.
Embodiment
In conjunction with above-mentioned accompanying drawing embodiment the utility model is described in detail again.
The automatic vent control valve comprises the upper shell 1 and the lower shell body 17 of connection sealed to each other shown in Fig. 1-2, upper and lower casing adopts steel plate one time punching molded, to guarantee dimensional accuracy.The valve body 12 at upper shell top is tightly connected by tightening nut 9 and seal ring 11; have transverse row pore 4 on the valve body; be provided with the spool 7 that is tightly connected by seal ring 8 in the valve body; both are threaded; "+" font pore 6 on the spool communicates with the external world and can communicate with the transverse row pore simultaneously, and the spool lower end is embedded with seal ring 10, and the top is provided with by the fastening removable dust-proof cover 5 of screw; prevent that dust, rubbish from falling into, play the effect of protection spool.
The bottom of valve body 12 is the pistons 14 that are embedded with the up and down slippage of seal ring 13, and sealing circle end face is spherical shape, and it forms the sealed faying face of high leak tightness with the seal ring 10 of spool lower end, adopts the silica gel making, and is high temperature resistant, ageing-resistant, durable in use.Lower part of piston is hinged by bearing pin 16 and connecting rod 3, and this interlinking lever end is connected with the flange that is extended by valve body by coupling shaft 15, and because of the needs of the upper and lower slippage lifting of piston, the coupling shaft attachment hole of interlinking lever end is processed into long-round-shape.The other end of connecting rod connects ball float 2.
Circular arc is made in lower shell body bottom surface 19, more helps the water energy quick drain in the outlet valve when water tank is discharged water, and ball float falls rapidly, and air is entered by exhaust port; Guarantee the water tank smoothness that discharges water.And water strainer 18 is set in the lower shell body water inlet, prevent from that pipeline impurity from entering to stop up exhaust port in the valve.
When water is gentle enter in the upper and lower casing cavity volume from water intake after, gas is just discharged from this valve outlet hole, when reaching certain water level in the cavity volume, ball float just floats, driving piston by connecting rod rises, make the seal ring on the piston tightly combine the junction plane that forms high leak tightness, promptly finished the function of not draining of exhaust with seal ring on the spool.As there not being water in the cavity volume, ball float just relies on gravity by connecting rod piston to be left behind, and the exhaust passage is opened again.
