Description

A kind of water supply line disappears pressure frost valve

Technical field

The utility model is related to a kind of valve, especially a kind of equivalance disappear companding chamber siphon water-saving water supply line it is antifreeze Valve.

Background technology

Valve is the control unit in fluid delivery system, with cut-off, regulation, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting Or the function such as overflow pressure relief.For the valve of fluid control systems, from simplest stop valve to extremely complex robot control system(RCS) In various valves used, its kind and specification are quite various.Valve can be used to control empty gas and water, steam, various corrosivity to be situated between The flowing of all kinds fluid such as matter, mud, oil product, liquid metal and radiating medium.In daily life, we are through common To valve be all mounted in valve on water pipe.Traditional aqueduct valve, generally comprises valve body, be installed with valve body with valve body The water inlet pipe and outlet pipe of chamber connection, are provided with the water supply valve seat that water inlet pipe is connected with outlet pipe, water supply valve seat in body cavity It is slidingly sealed on inwall and is combined with water supply valve plug.When using, by adjusting whether water supply valve plug and the sealing of water supply valve seat come real The unlatching and closing of existing valve.Conventional valves, simple structure is easy to operate, and weak point is, after valve closing, outlet pipe Interior temporary water cannot be discharged, and easily occur causing bursting by freezing water pipe failure in the winter time, bring inconvenience.At present on the market Common frost valve, typically will be stored in the water in valve body and water pipe and is discharged into the external world while valve is closed, so as to rise To antifreeze purpose, but it is that the water in water pipe is wasted, and is not economized on water not only the drawbacks of such frost valve, and to week Collarette border also results in influence, and during long-term use, waste water resource is more serious.

Utility model content

The technical problems to be solved in the utility model is directed to above-mentioned deficiency and provides a kind of rational in infrastructure, can be antifreeze, and Can economize on water, and easy to operate water supply line frost valve.

In order to solve the above technical problems, the upper valve core that can be moved up and down is provided with the upper valve intracoelomic cavity of this frost valve, it is zinc-plated Lifting pipe is provided with inside pipe, bottom spool is provided with lower valve body, upper valve core is connected by upper valve core bearing pin and moved together with lifting pipe, Lifting pipe lower end is connected with piston and bottom spool, so upper valve core, piston and bottom spool move the sky made inside water storage cylinder together Between size change and the switch of water inlet makes this valve reach with water and antifreezing effect.

The water supply line frost valve of this structure is to be provided with water storage cylinder by frost valve bottom, and water storage cylinder is compressed by piston Come realize can be antifreeze, and can economize on water, and it is easy to operate.

Low level water storage water distribution structure mainly includes being arranged on the water storage cavity inside water storage cylinder, and water storage cylinder is located under lifting pipe Portion, the top of water inlet is provided with piston in water storage cavity, piston outer periphery is slidingly sealed cooperation with water storage cavity wall.Piston and upper Connector lifting pipe is installed, so, piston is just become one structure by connector lifting pipe and upper valve core between valve element.When When the conversion in the torque direction that upper valve core passes through hand wheel shaft is changed into up and down, lifting pipe and piston are also moved.Raise Water pipe bottom is provided with pin hole mechanism, and bottom spool is connected with by pin hole mechanism, and bottom spool is slidingly sealed with lower valve body inwall matches somebody with somebody Close, and bottom spool has thinner part-structure and the inner chamber of lower valve body to leave gap, and the inner chamber of lower valve body is connected with water inlet And inner chamber becomes big herein, and seal failure when making the hermetic unit of bottom spool move to herein has water inlet to arrive so as to reach water The switching effect of water storage cylinder.The sealing of upper valve core and lifting pipe is provided with delivery port with the narrower portion merged in upper valve core, and upper The copper sheathing that valve element phase dynamic sealing coordinates is provided with circular hole between two range of movement of dynamic seal ring of upper valve core, this circular hole and upper valve The delivery port inner chamber of body communicates, and so, ensures that the connection between lifting pipe and delivery port.

When driving hand wheel shaft to rotate by rotating handle, hand wheel shaft coordinates to make the side of torque with the rectangular thread of upper valve core When to the direction that upper valve core is moved downward is changed into by direction of rotation, the piston and bottom spool moved together with upper valve core Move downward therewith, the space inside piston compression water storage cylinder, the hole for passing water through lifting pipe entered into lifting pipe, now after Continuous to move downward, the upper sealing gasket of bottom spool is entered among the relatively major lumen of lower valve body, water inlet and water storage cylinder, is pumped up water Connected between pipe, the delivery port of upper valve body, the water of water inlet starts to be flowed to delivery port, complete water supply action, now this water supply Pipeline frost valve is in opening.

When driving hand wheel shaft to rotate by rotating handle, hand wheel shaft coordinates to make the side of torque with the rectangular thread of upper valve core When to the direction that upper valve body is moved upwards is changed into by direction of rotation, the piston and bottom spool one moved together with upper valve body Motion upwards is played, now the ring structure of bottom spool enters into the dynamic sealing mating part of lower valve body, sealing cooperation is prevented The water of water inlet flows into water storage cylinder the inside, and this frost valve is closed, now due to piston upwards, the sky of water storage cylinder Between increase, the water in delivery port and lifting pipe, upper valve body is back to water storage cylinder through the apopore of lifting pipe of making a living, now water storage valve Plug is moved on continuing, and water storage valve plug lower section water storage cavity space gradually increases, the running water of lifting pipe and outlet pipe memory storage start to Backflow in water storage cavity below water storage valve plug.When upper limit position is moved on on lifting pipe, water storage valve plug reaches water storage cavity top, supplies Water valve plug reaches water supply valve seat top, and this water supply line frost valve is still in closed mode.Now, in lifting pipe and outlet pipe Water all flow back into water storage cavity, both avoided because of frozen pipe phenomenon caused by water in lifting pipe and outlet pipe, again will Water saves.When operating drive device to move down upper valve core, i.e. repeatedly said process, by the water weight in water storage cavity Newly confess, serve the effect of water saving.

Used as a kind of implementation, the drive device includes the hand wheel shaft in valve body, and hand wheel shaft is provided with square Shape screw thread, the top of upper valve core is provided with matched rectangular thread, torque direction is produced change, in the rotating shaft outside valve body It is installed with handle or handwheel.
