Abstract
A three-pipe two-way valve of the spheroidal valve core comprises a reduced tee, a telescoping pipeline and a ball valve core, wherein the reduced tee has large through caliber and small middle branch pipe caliber, and the big ends of the two telescoping pipelines are respectively arranged on the two ends of the through pipe pf the reduced tee. When the high pressure water flows into the valve through a tip end of the telescoping pipeline, the spheroidal valve core of the three-pipe two-way valve is closed with one end and the water flows outsides along the branch pipe under the water pressure; when the pressure of the high pressure water disappears, the water reflows to decompress aling the path vice versa.
Description
Technical field
The present invention relates to a kind of improvement of the unit control system that heats, the water pump switching control valve on the hydraulic pressure control valve in the tall building direct connection heating unit.Promptly high district heating system compression pump extrudes water-driven waterpower backwater control valve and opens the valve of closing on the hydraulic pressure control valve automatically.
Background technique
Tall building is on the increase.Realize directly being connected heating round tall building heating system and urban heating network, develop tall building direct connection heating unit.But all there is a common defects in they, and the valve on the hydraulic pressure control valve all is manually, can not realize that water pump automaticallyes switch, and makes the water pump time in turn bring difficulty.The present invention makes heating unit water pump automatic timing become possibility by turns.
Summary of the invention
The technical problem to be solved in the present invention is, make heating unit water pump automatic timing by turns, when current from straight-through two pipes wherein an end flow to and the other end by the spool shutoff, current flow out from middle arm, rely on the exit of pump water pressure to open waterpower backwater control valve, when water pump was out of service, water can flow back to pressure release automatically, and was a kind of safe and reliable, simple in structure, cost is low, and volume is little, the three-pipe two-way valve that is easy to manage.
In order to solve the problems of the technologies described above, the present invention has adopted following scheme: this three-pipe two-way valve is to adopt reducing tee, reducer pipe, and parts such as spheroidal spool or post taper valve core take welding or screwed connection to form.
The three-pipe two-way valve of spheroidal spool is made up of reducing tee, reducer pipe, spherical spool etc.Reducing tee is little for big-and-middle caliber of straight-through caliber, two reducer pipe major parts are installed in reducing tee straight-through tube two ends respectively, two reducer pipe microcephalies are connected on respectively between two exit of pump and the safety check, tee branch water receiving power backwater control valve hydraulic pressure control chamber, when starting of pump station wherein, the spool of three-pipe two-way valve under the water flow pressure effect, with another sealing, water flows to waterpower backwater control valve along arm, and waterpower backwater control valve is opened, and heating system begins circulation, when water pump out of service, to the moving pressure release that refluxes, close by waterpower backwater control valve along this route for current, cuts off the static pressure of high district heating system.When another water pump operation, spherical valve core repeats last process with the sealing of the other end reducer pipe.
The three-pipe two-way valve of cylinder taper valve core is made up of reducing tee, reducer pipe, cylinder poppet valve core etc.Reducing tee is big for straight-through caliber, a middle caliber is little, two reducer pipe major parts are installed in reducing tee straight-through tube two ends respectively, two reducer pipe microcephalies are connected on respectively between two exit of pump and the safety check, tee branch water receiving power backwater control valve hydraulic pressure control chamber, when starting of pump station wherein, the cylinder taper valve core of three-pipe two-way valve is along sliding in the straight-through tube under the water flow pressure effect, with another sealing, water flows to waterpower backwater control valve along arm, waterpower backwater control valve is opened, and heating system begins circulation.Out of service when water pump, to the moving pressure release that refluxes, close by waterpower backwater control valve along this route for current, cuts off the static pressure of high district heating system.When another water pump operation, the cylinder taper valve core repeats last process with the sealing of the other end reducer pipe.
This valve characteristics are: simple in structure, safe and reliable, stop misoperation.Make tall building direct connection heating unit water pump timing automatic become possibility by turns.
Above two types of three-pipe two-way valves of the present invention also are applicable to the miscellaneous equipment control system.
Description of drawings

Fig. 2 cylinder taper valve core three-pipe two-way valve structural representation.
Embodiment
Now the present invention will be further described in conjunction with the accompanying drawings: Fig. 1 is a spheroidal spool three-pipe two-way valve structural representation.Spheroidal spool three-pipe two-way valve is by reducing tee 1, reducer pipe 2, spherical spool 3 compositions such as grade, the miner diameter end of two reducer pipes 2 is respectively pipe 4 and manages 5, tee branch 6, two miner diameter ends of reducer pipe 2 are respectively pipe 4 and manage 5 and are connected on respectively between two pump outlets and the safety check, tee branch 6 water receiving power backwater control valve hydraulic pressure control chambers, when starting of pump station wherein, under the water flow pressure effect, the spheroidal spool 3 of three-pipe two-way valve is with the other end sealing, and water flows to waterpower backwater control valve by arm 6, waterpower backwater control valve is opened the heating system circulation.Out of service when water pump, current move pressure release along this route to refluxing.When another water pump operation, spheroidal spool 3 repeats last process with the sealing of the other end reducer pipe.
Fig. 2 cylinder taper valve core three-pipe two-way valve structural representation.Cylinder taper valve core three-pipe two-way valve is by reducing tee 1, reducer pipe 2, cylinder taper valve core 7 compositions such as grade, the miner diameter end of two reducer pipes 2 is respectively pipe 4 and manages 5, tee branch 6, two miner diameter end pipes 4 of two reducer pipes 2 and manage 5 and be connected on respectively between two exit of pump and the safety check, tee branch 6 water receiving power backwater control valve hydraulic pressure control chambers, when starting of pump station wherein, the cylinder taper valve core 7 of three-pipe two-way valve under the water flow pressure effect, with the other end sealing, current flow to waterpower backwater control valve along arm 6, waterpower backwater control valve is opened the heating system circulation.Out of service when water pump, current move pressure release along this route to refluxing.When another water pump operation, cylinder taper valve core 7 with the sealing of the other end reducer pipe, repeats last process along straight-through tube.
