Abstract
The utility model discloses a pneumatic automatic inflation valve for water tanks, comprising a valve body, a water inlet and a water outlet opened at two ends of the valve body, a fluid suction segment formed in the inner chamber of the valve body, an air vent opened at the smallest-diameter position of the suction segment, and a one-way valve installed on the air vent. Being simply structured, reliable and durable, the utility model can perform automatic air inflation of water tanks.
Description
The utility model relates to gas charging valve, relates in particular to the automatic gas charging valve into pneumatic-typed water tank air inlet inflation.
The pneumatic-typed water tank is few with its water consumption, and is easy to use and popular to people deeply.But this water tank need leave certain air, and in use for some time, these air can slowly reduce, thereby has a strong impact on the using effect of water tank.For this reason, people have to take water pipe apart to not timing, make the water emptying in the water tank, connect water pipe again and use, and both doing like this wastes time and energy, and also bring many troubles to people's life.
The purpose of this utility model provides the automatic gas charging valve of a kind of pneumatic-typed water tank, and it can be inflated water tank when using water tank automatically, and simple in structure, reliability and durability.
The purpose of this utility model is to realize like this; The automatic gas charging valve of pneumatic-typed water tank, the fluid suction effect section that it forms by valve body, the water intake that is arranged on the valve body two ends and water outlet, at the inner chamber of valve body, be opened in the ventilating hole at the minimum place of suction effect section diameter, the one-way valve that is installed on the ventilating hole constitutes.In order to save material, valve body becomes the wasp waist shape, is provided with stiffening rib at the wasp waist part of valve body.
During use, as long as the utility model is installed between the water intake and water pipe of pneumatic-typed water tank.When the pneumatic-typed water tank discharges water, tap water enters automatic gas charging valve under pressure, because flow velocity maximum when body cavity has fluid suction effect section, tap water to flow through its diameter minimum place, thereby on the valve body madial wall, form negative pressure, this negative pressure is the water in the one-way valve gas-entered passageway that is communicated with ventilating hole of sucking-off at first, drive the nonreturn valve core action then, extraneous air is entered in the pneumatic-typed water tank, thereby finish automatic gas replenishment process.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
With reference to the accompanying drawings, the two ends of valve body (1) are provided with water intake (7) water outlet (11), and they and valve body (1) fuse, and the inner chamber of valve body (1) forms the fluid suction effect section of being made up of oared segrne pii (8), (10) and minimum diameter section (9).Locate to have a ventilating hole (14) in minimum diameter section (9), ventilating hole (14) locates to be equipped with an one-way valve, check valve body (16) fuses with valve body (1), be connected with the valve gap (2) of bringing pore (12) on the check valve body (16), seal ring (3) be housed at the junction point of check valve body (16) and valve gap (2).The sealing gasket (4) that is used to be sealed into pore (12) is installed on the nonreturn valve core (5), between nonreturn valve core (5) and check valve body (16) spring (6) is installed, ventilating hole (14) is communicated with the gas-entered passageway (15) of one-way valve.In order to save material, valve body (1) is made the wasp waist shape, for reinforced structure intensity, is provided with stiffening rib (13) at this wasp waist part.When not using the pneumatic-typed water tank at ordinary times, sealing gasket (4) can intercept being communicated with of inlet hole and gas-entered passageway (15) effectively under the effect of spring (6) and hydraulic pressure.
The utility model is simple in structure, and is reliability and durability, when using the pneumatic-typed water tank, because the gas suction effect makes water tank can replenish air automatically when supplementing water, very easy to use.
Claims (4)
1, the automatic gas charging valve of gas formula setting-out case, it is characterized in that it being, constitute at the fluid suction effect section of body cavity formation, the ventilating hole that is opened in the minimum place of suction effect section diameter, the one-way valve that is installed on the ventilating hole by valve body, the water intake that is arranged at the valve body two ends and water outlet.
2, the automatic gas charging valve of pneumatic-typed water tank according to claim 1, it is characterized in that one-way valve be by the check valve body that is connected with ventilating hole, be screwed in the valve gap that has inlet hole on the check valve body, nonreturn valve core that the sealing gasket that is used to be sealed into pore is installed is installed in the spring between nonreturn valve core and the check valve body, be opened in the gas-entered passageway that is communicated with ventilating hole in the check valve body and constitute.
3, the automatic gas charging valve of pneumatic-typed water tank according to claim 2 is characterized in that the valve gap on the said one-way valve and the junction point of check valve body are equipped with seal ring.
4, the automatic gas charging valve of pneumatic-typed water tank according to claim 1 is characterized in that valve body becomes the wasp waist shape, is provided with stiffening rib at the wasp waist part of valve body.
