Summary of the invention
The problems and shortcomings that exist for above-mentioned prior art, the utility model adopts the device consisting of buffering gas tank, valve body, ball valve, the thin-wall stainless steel matter slack tank that buffering gas tank is hollow, valve body is the four-way shape member that is provided with interface, left interface, right interface, internal channel, lower channel, buffering gas tank is connected with upper interface, and ball valve is located in lower channel, when application is installed, buffering gas tank vertically upward, left interface, right interface is connected with the water intake of water terminal with interior conduit respectively, tap water by valve body enters buffering gas tank under the effect of hydraulic pressure, by buffering gas tank in original air compressing to the top of cushioning gas tank, form so-called pressurized air spring, in interior conduit, because opening soon tap, there is water hammer, water hammer is cushioned the pressurized air snubber in gas tank, thereby protected water terminal and interior conduit to avoid the technological scheme of water hammer harm, a kind of family expenses water hammer baffle safety valve is provided, be intended to by the water hammer in the pressurized air snubber interior conduit in buffering gas tank, make water terminal and interior conduit, reach the object of avoiding water hammer harm.
The purpose of this utility model is achieved in that a kind of family expenses water hammer baffle safety valve, comprise buffering gas tank, valve body, ball valve, wherein: described buffering gas tank is the stainless steel components of hollow, lower openings, thin wall cylindrical tank shape, the bottom of buffering gas tank is provided with the external screw joint that the upper interface with valve body is connected and is called screw mouth;
Described valve body is the tubular thin wall type copper matter of the cross four-way member that is provided with interface, left interface, right interface, internal channel, lower channel, described upper interface be positioned at valve body above, the round tubular inwall place of upper interface is provided with internal thread; Described left interface is positioned at the left side of valve body, and the round tubular inwall place of left interface is provided with internal thread; Described right interface is positioned at the right side of valve body, and the round tubular outer wall place of right interface is provided with outside thread; Described lower channel be positioned at valve body below, lower channel is provided with the ball valve consisting of ball valve core, valve rod, handle; Described internal channel is positioned at the cavity of the inside center of valve body, and internal channel communicates with described upper interface, left interface, right interface, lower channel;
Buffering gas tank is positioned at the top of valve body, and the buffering described screw mouth of gas tank and the described upper sealing joint of valve body are fixedly connected with.
Working principle and beneficial effect
When application is installed, buffering gas tank vertically upward, interior conduit is connected with left interface through triangle vavle, right interface is connected with the water intake of water terminal, tap water enters water terminal by left interface, internal channel, the right interface of valve body, and the tap water of the valve body of flowing through, under the effect of hydraulic pressure, through upper interface, enter buffering gas tank and to the top of cushioning gas tank, form so-called pressurized air spring by cushioning original air compressing in gas tank; In interior conduit, when opening soon tap water hammer occurs, the pressurized air in buffering gas tank is water hammer pulse snubber, thereby protected water terminal and interior conduit to avoid the harm of water hammer.
This device is the pressurized air in gas tank by buffering, and the water hammer in snubber interior conduit has ensured that water terminal and interior conduit avoid the harm of water hammer.In the long-term work of this device, because tap water can dissolve in part air and be taken away, there is deficiency in the pressurized air that makes to cushion in gas tank, now, close triangle vavle, the water route that cuts off interior conduit and this device contacts, and opens the ball valve of described lower channel, after the water in emptying buffering gas tank, close described ball valve, open triangle vavle, reclose this device and contact with the water route of interior conduit, the pressurized air that makes to cushion in gas tank is restored.
Above-mentioned, the utility model adopts the device consisting of buffering gas tank, valve body, ball valve, the thin-wall stainless steel matter slack tank that buffering gas tank is hollow, valve body is the four-way shape member that is provided with interface, left interface, right interface, internal channel, lower channel, buffering gas tank is connected with upper interface, and ball valve is located in lower channel, when application is installed, buffering gas tank vertically upward, left interface, right interface is connected with the water intake of water terminal with interior conduit respectively, tap water by valve body enters buffering gas tank under the effect of hydraulic pressure, by buffering gas tank in original air compressing to the top of cushioning gas tank, form so-called pressurized air spring, in interior conduit, because opening soon tap, there is water hammer, water hammer is cushioned the pressurized air snubber in gas tank, thereby protected water terminal and interior conduit to avoid the technological scheme of water hammer harm, having overcome prior art exists water terminal to lack the problems and shortcomings that water resistant is hammered the device that endangers safety into shape, a kind of family expenses water hammer baffle safety valve providing, by the water hammer in the pressurized air snubber interior conduit in buffering gas tank, water terminal and interior conduit have been reached and avoid the object that water hammer endangers.
