Abstract
The utility model belongs to a mechanical water-saving ice-free valve, which comprises a closed water cavity, an on-off valve, the interface of a water outlet pipe, etc. When a handle 1 is pressed, a push rod 8 and a valve ball 11 are pushed downwards and the valve is opened for water inflow, and meanwhile, accumulated water is discharged. When the water returns, the water flows into a water jacket 6 through the self-weight back flow of the accumulated water and the negative pressure suction force of an elastic jacket. The water-saving ice-free valve has the advantages of convenient operation, fluid water outflow and complete back flow.
Description
The utility model belongs to mechanical valve, and what be specially that a kind of water supply line outlet pipe uses does not freeze valve.
Indoor outlet conduit is influenced by winter climate, very easily freezes, and influence is used.Existing frost valve is open substantially.During valve closing, be exposed to ground surface and discharge by drainage, both wasted the water source, again easy contamination and plugging with the ponding of water inlet.
CN2040573U discloses " a kind of frost valve ", has adopted floating plug and vent plug to adjust the pressure difference of water cavity, but its gas-liquid mixed is subjected to effects of air pressure during the water backwater, is difficult to fall after rise fully.
The purpose of this utility model provides a kind of water outlet smoothness, and backwater is complete, and the control break-make is easy to water saving and does not freeze valve.
The purpose of this utility model is achieved by the following scheme.
It is made up of closed water cavity, on-off valve, outlet pipe interface three parts.Closed water cavity is fixed in the valve body by an elasticity water jacket, and the compression plate effect of elasticity water jacket also links by pressure head, fastening piece and operating grip, and the sliding mandril of pressure head and on-off valve is in same footpath line position.Elasticity water jacket inner chamber communicates with outlet pipe with the water cavity passage, and isolated with the body cap inner chamber.Specifically, the water cavity passage of elasticity water jacket can communicate by valve body water cavity passage 18, negative pressure pipe 17 and outlet pipe 16.The outlet pipe interface includes water receiving pipe 13, and water receiving pipe 13 connects the jet pipe 15 of a little internal diameter with internal thread, and outside thread connects the sleeve pipe 14 of a large diameter, and connects outlet pipes 16 by sleeve pipe 14.The valve operation handle can be done radial motion by the orienting cover or the screw-casing that cooperatively interacts in conduit 2, drive pressing plate 20, pressure elasticity water jacket 6.Exhalant canal is opened to unidirectional on-off valve push rod 8, valve ball 11 in pressure head 5 tops.Valve ball 11 is with spring 12 supporting location, and spring 12 is by having the fastening piece location of through hole.Valve ball 11 cooperates opening/shutting valve with valve pad 10.End in contact push rod 8 slides and inserts in the positioning through hole of valve body 9 on the valve ball.
Its working principle is such.Do not freeze valve except that handle, its body can be imbedded the underground layer that do not freeze.Depress or when screwing off handle, drive pressing plate pressure elasticity water jacket, the water in the water jacket can flow out from outlet pipe by water cavity passage, negative-pressure pipeline on the one hand.On the other hand, when pressure head contacted with on-off valve push rod 8, push rod backed down the valve ball downwards, and discharge through water receiving pipe 13, jet pipe 15, the outlet pipe 16 of outlet pipe interface at the water source.Because the internal diameter of jet pipe 15 is less than the internal diameter of outlet pipe 16 and jet pipe 15, the radial clearance of its external diameter and outlet pipe 16 is than little with the gap of sleeve pipe 14.Since sectional area dwindle variation, the flow velocity of water increases, and forms pressure difference up and down at the spout of jet pipe 15, forms negative pressure in the sleeve pipe 14, has eliminated the dynamic pressure of discharge pressure to the elasticity water jacket.Make operation more light, water outlet is more smooth and easy.
Mention or when screwing out handle, the valve ball is closed the water source break-make, the ponding of outlet pipe 16 restores the vacuum flow rebound elasticity water jacket of formation by deadweight and elasticity water jacket.
The utility model is on probation through model machine, operate light, the draining smoothness, backwater is complete.Can prevent that valve from freezing, backwater also can make full use of, and work is reliable.
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Accompanying drawing does not freeze the valve principle assumption diagram for water saving.
The cross sections that are installed in the cylinder body 4 are polycyclic elasticity water jacket 6, upper end closed, and the lower end breakdown also is fixed between body cap and the housing 9 with outer rim, forms totally-enclosed water cavity.The volume of water cavity is slightly larger than the volume of outlet pipe 16.Round nut 3 is unified into a steel body with handle 1, pressing plate 20, elasticity water jacket 6, pressure head 5.The space of elasticity water jacket 6 outer surfaces and cylinder body 4 inner chambers communicates with atmosphere by the negative pressure pore 21 on the conduit 2, and is poor with balance pressure, guarantees the hypertonic of elasticity water jacket 6.Over against footpath, pressure head 5 lower ends line position, push rod 8 can be subjected to pressure head 5 effects, does radial motion in the positioning hole of valve body 9, to open and close the water source passage.Elasticity water jacket 6 communicates with outlet pipe 16 by water cavity passage 18 and negative pressure pipe 17.Valve ball 11 cooperates break-make with spring 12 supporting location with valve rubber cushion 10.Jet pipe 15 external diameters are less than water receiving pipe 13 and outlet pipe 16, and sleeve pipe 14 internal diameters are greater than the internal diameter of jet 15.
Among the figure, 7 are O shape circle, and 19 is the water cavity passage.
