Description
Technical field
The utility model belongs to float valve field; The sealing that is specifically related to lead ventilation float valve.
Background technique
Strong self priming pump is by increasing and inhale vacuum system in the drive mechanism of pump, is that first pump starts suction vacuum system when starting, and gas in pump is discharged, and low liquid level liquid is drawn in the pump housing, then stops inhaling vacuum system, and pump runs well, pumps liquid.The work of suction vacuum system is air-breathing, exhaust, can not allow the liquid of being pumped enter into suction vacuum system while pumping liquid, therefore needs reliable sealing ventilation float valve.
The poor sealing of existing water check valve, often will be transferred medium and be drawn in vacuum system, cannot complete self-priming process.
Summary of the invention
The technical problems to be solved in the utility model is the poor sealing of existing water check valve, often will be transferred medium and be drawn in vacuum system, cannot complete self-priming process; And guiding sealing ventilation float valve is provided.
The utility model guiding sealing ventilation float valve guarantees that Strong self priming pump can normally move.
For solving the problems of the technologies described above, the utility model guiding sealing ventilation float valve comprises: comprise valve gap, valve body, ball float and automatic control pressure vent, described valve gap is located at valve body top and is bolted, between valve gap and valve body, be provided with seal ring, valve body bottom is fixedly connected with flange plate, valve inner is provided with retainer ring, retainer ring inside is provided with guide sleeve, in guide sleeve, be provided with pilot hole, in valve gap, be provided with seal seat, ball float is located in valve body, the top of ball float is connected bottom simultaneously and is connected with lower link with upper connecting rod, upper connecting rod is provided with tapered rod, valve block is equipped with in tapered rod bottom, valve block bottom is fastening with locking nut, stretch out outside valve gap through pilot hole on the top of upper connecting rod, lower link is provided with balancing weight, stretch out outside valve body through guide sleeve the bottom of lower link, , seal seat lower openings is horn-like, match with horn-like opening, the top end of valve block is arch, and on valve gap, the top of seal seat is provided with automatic control pressure vent.
Working principle of the present utility model: guiding sealing ventilation float valve of the present invention is vertically arranged in the suction line of Strong self priming pump, when Strong self priming pump is started working when air-breathing, ball float in float valve and upper connecting rod, lower link and valve block are all in the lower end of float valve, valve block and seal seat depart from, therefore, float valve is in unimpeded state, in float valve, gas can unresistedly pass through, suck liquid in floating ball body after, ball float starts to rise, work as ball float, upper connecting rod, lower link, valve blocks etc. reach valve block and seal seated connection after specified altitude and touch and seal, now in float valve, gas and water all can not pass through, keep sealing state.Valve body lower end guide sleeve is, by upper connecting rod, lower link, ball float and valve block are remained on to middle position, guarantee valve block and any moment of seal seat tightly in windage valve liquid pass through, prevent that liquid from being entered and being inhaled in vacuum system by valve body upper end; Balancing weight is according to different exhaust speed and rate of air sucked in required, to regulate the rate of climb of ball float and valve block; Automatic control pressure vent is self-bleeding automatic control pressure vent after valve block and seal seat are sealed to certain hour, and after outlet valve exhaust, ball float and connecting rod valve block all together fall back to float valve lower end, prepare suction and discharge work for the second time.
Liquid rises, ball float raises with liquid level, when liquid level is raised to certain altitude, the opening of the tight combination of valve block and seal shutoff seal seat, after gas emptying, liquid also cannot enter vacuum system inside, has certain distance between valve block and liquid level, the better tightness of the sealing ventilation float valve that therefore leads.
Described balancing weight is fastened on lower link by clamping bolt is installed on sidewall, according to different pumping speed, by regulating height and the weight of balancing weight, the sealing speed of regulation valve body.
The utility model is rational in infrastructure, is skillfully constructed, and is suitable for large-scale promotion and uses.
