Description

The detachable water valve that cleans

Technical field

The utility model relates to a kind of water valve, refer to especially a kind of can removal handle so that the detachable cleaning water valve that cleans.

Background technique

Water valve is indispensable a kind of daily necessities during people live from the beginning, various water valves from the beginning are located at the outlet end of water pipe, be used for the control switch controlled water flow, for our life has brought convenience, common water valve typically uses the water sealing structure that rotates back to pressure type rubber seal or the sealing of ball formula back pressure, in use, the drinking water quality of different regions exists certain difference, in the harder place of water quality, water can form precipitation when flowing through water valve on the main member of valve, or the surface of water valve parts and water valve reacts and condenses and produce precipitation of scales, have influence on the slickness of water valve parts surface, and then cause between the water valve parts poorly sealed, sealability reduces, these the at present common rotation rubber water valves or the sealed member of ball formula water valve all are will be pressed on water valve outlet pipe sealing station place to seal always, therefore can not take water valve at any time apart to inner seal member being taken off to clean, cause the water valve life-span to reduce, not only cause the wasting of resources, and user's user cost is raise, the opening of common water valve all is provided with the filter screen of large granular impurity in the filtered water in addition, large granular impurity can be filtered and be deposited in fire hose draught animals place, cause the silence of water tap place impurity, do not clean for a long time and can cause hose nozzle to block.

The model utility content

Technical purpose of the present utility model is for the detachable cleaning water valve that a kind of cost is low, be convenient to install and use is provided.

For realizing above technical purpose, detachable cleaning water valve of the present utility model comprises valve body, conical sealing block, the axle positioning block, spring and rotatable flexible valve cover, this valve body has the water inlet pipe mouth and the valve cover mouth of coaxial setting, effluent pipe mouth is provided with between water inlet pipe mouth and valve cover mouth, be provided with conical sealed mouth in the intake pipe tube wall between effluent pipe mouth and water inlet pipe mouth, inwall is equipped with internal thread near water inlet pipe mouth and the valve cover mouth, valve cover has valve shaft and valve handle, the valve shaft outside of axle positioning block and valve cover is provided with outside thread, axle positioning block middle part is provided with the axle positioning hole that is used for the axle location, the valve shaft middle part is provided with the location indent, this taper shape sealing block protrudes to the both sides one and is formed with positioning rod and depression bar, this taper shape sealing block is arranged in the intake pipe and with conical sealed mouth by water inlet pipe mouth one side and is sealed and matched, spring housing is located on the positioning rod of conical sealing block, the axle positioning hole pressure spring of axle positioning block be sheathed on the positioning rod and with the water inlet pipe mouth screw-internal thread fit, the valve shaft of valve cover and valve cover mouth screw-internal thread fit, the location indent of valve shaft pushes the depression bar setting of conical sealing block, can roof pressure when this valve cover is tightened conical sealing block, make between this taper shape sealing block and the conical sealed mouth and produce the crack, this detachable water valve that cleans is opened, thereby water is flowed out, otherwise, when unclamping or take off valve cover, this taper shape sealing block cooperates with conical sealed mouth extruding, watertight is no longer flowed out, this detachable water valve that cleans cuts out.

Above-mentioned non-return seal arrangement also comprises two elastic seal rings, and these two seal rings are sheathed on respectively on the valve shaft of conical sealing block and valve cover.

The effluent pipe mouth place of above-mentioned detachable cleaning water valve is provided with filter screen.

For avoiding spring to corrode, cause conical sealing block of water tap and conical sealed mouth poorly sealed, above-mentioned spring is a stainless steel spring.

Beneficial effect: because detachable rinse water threshold switch has adopted the sealing configuration that unclamps non-return, should detachably clean water valve when unclamping or take off valve cover, this taper shape sealing block cooperates with conical sealed mouth extruding, watertight is no longer flowed out, this detachable water valve that cleans cuts out, thereby this water valve can be sealed.
