Abstract
The utility model relates to a three-way valve, in particular to the utility model of a reverse linkage rotary three-way valve. Two adjusting valves are arranged on the three-way pipe adjusting body of the three-way valve in parallel; the adjusting valves are provided with two rotating connection adjusting screws in parallel; when the rotating handle of the upper shaft end of one of the rotating connection adjusting screws is rotated, the two screws can be provided with a reverse linkage rotation synchronously together; however, the lower ends of the two screws are used to adjust a mixing fluid by the opposite switching of two valves which are positioned in the middle of the three-way pipe and separated by a middle plate; the pipe wall of a mixing pipe passes through a rubber plug and the slant inserting hole of each of a screw cap; a wet thermometer with a liquid bulb which is coated with a gauze or a sponge can display mixing temperature; a single valve is additionally connected with the outlet of the mixing pipe; therefore, the mixing fluids of places where different pressure fluids are mixed can be controlled.
Description
The utility model is about three-way valve, particularly the contragradience interlock is with the invention of revolving three-way valve, this three-way valve is on the control agent of three-way pipe and two modulating valve of array apparatus, it has two adjusting screw that screw mutually side by side, rotation wherein on the screw axle head revolve hand, two-screw can the oppositely common interlock rotation of contragradience, and makes the two-screw lower end, two valve opening and closings that separated by the middle metal plate of three-way pipe central authorities are opposite, regulate fluid-mixing.This three-way valve is a kind of controlling device that belongs to the fluid mixing apparatus three-way pipe of shower hot and cold water mixed pipe line (as be used for).
Three common water service pipes are used for shower hot and cold water mixed pipe line with two modulating valve separate regulation, because hot and cold water pressure varies in size, the water temperature shakiness can appear in pressure instability, regulate the defect of difficulty.The hot and cold water mixing tee pipe of the 67 page of introduction in " the 4th national teenager's science creativity and innovation match win a prize portfolio ", inventor Liu's drench adds metal plate in the lastblock in the central authorities of three-way pipe.Metal plate has cut off the impact of high-pressure water flow to the low pressure current in the utilization, and has utilized the entrainment effect of high-pressure water flow to the low pressure current, thereby has improved the hot and cold water mixed characteristic greatly.But two modulating valve that are used for three water service pipes can only separate regulation, and interlock is regulated jointly.
Task of the present utility model provides a kind of modulating valve, and the high pressure that it is separated by the middle metal plate of three-way pipe central authorities and two valves of low-pressure fluid pipe can be regulated by the oppositely common interlock of contragradience, can improve the fluid mixed characteristic again, and can show the fluid-mixing temperature.
Its solution is: also two modulating valve of array apparatus are arranged on the control agent of three-way pipe, its two adjusting screw screws side by side mutually, the last axle head of one screw is equipped with and revolves hand, rotates to revolve hand, can make the oppositely common interlock rotation of two-screw contragradience in the tangent control agent internal thread of two circle cross-sections.In the lower end of two adjusting screw are two valves of high pressure and low-pressure fluid pipe, middle metal plate by three-way pipe central authorities separates, can cut off the impact of high-pressure liquid like this to low-pressure fluid, and utilize the entrainment effect of high-pressure liquid to low-pressure fluid, and improve the fluid mixed characteristic, in mixing tube inside beyond the metal plate outward edge above on the tube wall, drill through an inclination jack, pass rubber stopper and screw cap, insert the wet bulb thermometer that vacuole is wrapped with Sha Bu or sponge, can show the fluid-mixing temperature.
In order to remedy the contragradience interlock with the deficiency of revolving three-way valve, it is regulated the flow and the opening thereof of back fluid-mixing or closes, and can be controlled by the single modulating valve that the mixing tube outlet port is hinged with in addition.
With the function of revolving each parts of three-way valve, its Manufacturing material can be used metal, alloy, in the fluid mixed pipe line of two kinds of lower different pressures of temperature, also can use engineering plastics according to the contragradience interlock.
Accompanying drawing has been described an embodiment of the present utility model.
Accompanying drawing is that the contragradience interlock is with the structural representation that revolves three-way valve.
Accompanying drawing has been described the contragradience interlock with revolving three-way valve, and it has three-way pipe (1) and control agent (2 ').Three-way pipe (1) divides high-pressure fluid line (1c), low-pressure fluid pipe (1a), mixing tube (1b) and control agent nut (2).Three-way pipe (1) central authorities are middle metal plates (3), and it does not have screw thread by low-pressure fluid pipe (1a) one side, because adjusting screw (4) top helical thread portion screws mutually with adjusting screw (5), and revolves less than middle metal plate (3) position, and bottom beam barrel (6) does not have screw thread again.And middle metal plate (3) is by there being screw thread, so that adjusting screw (5) is pushed down valve (8) above being screwed into valve port (7) more than the valve port of high-pressure fluid line (1c) (7).Thread part screwed in control agent nut (2) below control agent (2 ') was outside, and internal cross section is two tangent circles, and its internal surface has screw thread, and with precession or screw out adjusting screw (4,5), round mouth is rotary with screw cap (9,13) on two.Screw thread is arranged at adjusting screw (4) top, and its underpart is the beam barrel (6) that outer surface does not have screw thread and hollow, blocks valve (10), and valve (10) below is valve port (11).The no screw thread of adjusting screw (5) top rotating shaft (12), screw cap (13) is passed in its upper end, fixedly revolves hand (15) with nut (14), and its underpart outer surface has screw thread, and foot hollow, blocks valve (8), and valve (8) below is valve port (7).When hand (15) is revolved in rotation, adjusting screw (5) screws out and ascending Open valve (8) from down to up, perhaps precession from top to bottom and descending throttle down (8), simultaneously, drive the oppositely common interlock rotation of adjusting screw (4) contragradience, precession from top to bottom and descending throttle down (10) perhaps screw out and ascending Open valve (10) from down to up.In mixing tube (1b) inside beyond metal plate (3) outward edge above in the inclination jack (16) on the tube wall, pass rubber stopper and screw cap (17), insert the wet bulb thermometer that vacuole is wrapped with Sha Bu or sponge, can survey the temperature that fluid-mixing is shown, till being adjusted to suitable temperature.Regulate the flow and the opening thereof of back fluid-mixing or close, by mixing tube (1b) outlet port in addition a single modulating valve of tipping control.
