Abstract

The utility model relates to a valve for tap water. The valve for tap water is characterized in that a trapezoidal thread 4 is arranged between a rotary handle 3 and a valve body 6 to form an outer thread jack. A valve rod 5 is pushed to up and down move, and a valve sheet 8 and a valve seat 12 are combined and separated. A sealed ring 2 is additionally arranged between the valve rod 5 and the valve body 6. A valve sheet support 11 and the valve sheet 8 are installed on one side of the water inlet of the valve body 6. The pressure of water is used for increasing the sealed performance of the valve for tap water and reducing the rotary closing resistance of the valve for tap water. The defects that the opening and the closing of the traditional tap are not flexible, and the traditional tap has short service life and leakage are solved. The valve for tap water has simple structure and low cost. The valve for tap water can widely substitute a tap used at present. The maintenance workload of the valve for tap water is reduced, and the water saving effect of the valve for tap water is marked.

Description

Valve for running water

The utility model discloses a kind of valve that is used on the water supply pipe, particularly flowing water Valve---water tap.

Before the utility model was made, although traditional water tap profile is various, its basic structure was to match with a very heavy promotion valve block of spiral and valve seat.Compress and seal the function that reaches by current.Major defect is that the very heavy rapid wear of spiral causes and is not closed completely; Leak between valve rod and stuffing box packing; Switch is dumb etc.

Invention task of the present utility model provide a kind of switch flexibly, the running water outlet valve of long service life, good airproof performance.

Figure of description is a structure cutaway view of the present utility model.Among the figure: 1 swing handle retaining screw, 2 seal rings, 3 swing handles, 4 trapezoidal threads, 5 valve rods, 6 valve bodies, 7 water outlets, 8 valve blocks, 9 water intakes, 10 screw threads, 11 valve block holders, 12 valve seats.

Invention main points of the present utility model are:

1, there have trapezoidal thread 4 to constitute between swing handle 3 and valve body 6 to be externally threaded very heavy, promotes valve rod 5 and move up and down, make valve block 8 and valve seat 12 in conjunction with or separate and reach on-off action.

2, between valve rod 5 and valve body 6, install the sealing that seal ring 2 solves valve rod 5 additional.

3, in water intake one side of valve body 6 valve block holder 11 and valve block 8 are installed.Rotational resistance when the sealing of utilizing the interior pressure of water supply pipe to increase valve block 8 is effectively closed with minimizing.

Following according to Figure of description, specifically introduce essential structure of the present utility model: a kind of running water valve, comprise known valve body 6, by water outlet 7 and water intake 9 that valve seat 12 is separated into, it is characterized in that in valve body 6 and water intake 7 and valve rod 5 of valve seat 12 coaxial installations.Valve rod 5 one ends are with seal ring 2 and are sealed sliding movingly with valve body 6, the top is fixed a swing handle 3 by swing handle retaining screw 1 and is with valve rod and is slidingly matched, it is very heavy that swing handle 3 internal surfaces and valve body 6 outer surfaces have trapezoidal thread 4 to match to constitute spiral, the centre that the other end of valve rod 5 passes valve seat 12 matches with valve seat 12 at the valve block 8 that water intake 9 one sides connect valve block holder 11 picking-ups, valve inleting water mouth 9 inwalls have screw thread 10, and outer wall is the hexagon nut shape.

Working principle of the present utility model is such.When hand-screw changes swing handle 3, the very heavy valve rod 5 that can make of spiral rises or descends along axis, make valve block 8 and valve seat 12 in conjunction with or separate, thereby make intake-outlet link up or end, finish the switch of valve.Because hydraulic pressure can promote when valve closes valve rapider laborsaving and tight to the active force of valve block 8 in the water intake.

Major advantage of the present utility model shows as: outer trapezoidal thread is easy to lubricate, diameter is big, the life-span is long; Friction between valve rod and the valve body is little thereby open rotation flexibly; Adopt seal ring draught excluder rod seal good; The part of whole valve is few, and simple structure technology is uncomplicated reduces production costs.Adopt the utility model to replace traditional water tap to reduce and produce and maintenance expenses, the usage appearance quality of water saving and raising water tap.Real is the good merchantable brand of dwelling house, hotel's water supply equipment.

Among the embodiment of the present utility model, the O RunddichtringO that seal ring can adopt top-quality rubber to make, trapezoidal thread can adopt the double trapezoid worm structure to increase very heavy stroke, and valve block can adopt rubber pad, and valve block holder and valve rod adopt cold-heading to be integral.The material of all the other each parts can be identical with traditional water tap.

Claims

1, a kind of running water valve, comprise known valve body 6, the water outlet 7 and the water intake 9 that are separated into by valve seat 12, it is characterized in that in valve body 6 and water intake 7 and valve rod 5 of valve seat 12 coaxial installations, valve rod 5 one ends are with seal ring 2 and are sealed sliding movingly with valve body 6, the top is fixed a swing handle 3 by swing handle retaining screw 1 and is with valve rod and is slidingly matched, it is very heavy that swing handle 3 internal surfaces and valve body 6 outer surfaces have trapezoidal thread 4 to match to constitute spiral, the centre that the other end of valve rod 5 passes valve seat 12 matches with valve seat 12 at the valve block 8 that water intake 9 one sides connect valve block holder 11 picking-ups, valve inleting water mouth 9 inwalls have screw thread 10, and outer wall is the hexagon nut shape.

2,, it is characterized in that the O RunddichtringO that seal ring 2 can adopt top-quality rubber to make according to the described running water valve of claim 1.

3,, it is characterized in that trapezoidal thread 4 can adopt the double trapezoid screw thread according to the described running water valve of claim 1.

4,, it is characterized in that valve block 8 can adopt rubber pad according to the described running water valve of claim 1.
