Description
Technical field
The utility model relates to a kind of drainage valve, specifically is a kind of spool accurate positioning and the drainage valve that easily resets.
Background technology
At present, in the sewer of civilian construction, bathroom, in order to intercept down in the water drainage pipe in the peculiar smell inlet chamber, usually can be or on the water gutter drainage valve is installed down in outfall.The drainage valve of prior art comprises valve body, spool, handle body, described valve body comprises water inlet, sealing mouth and outfall, described spool is arranged in the valve body, the lateral wall of spool is provided with " zero " shape sealing ring that matches with valve body sealing mouth, the valve interior wall at described sealing mouth place is up big and down small conical surface setting, described handle body and valve body are rotatably connected, and the end of handle body is set to crankshaft structure, the crankshaft structure of described spool and handle body flexibly connects, be that the spool bottom is provided with a socket, the width of described socket is greater than the diameter of crankshaft structure cross section, when packing spool into, put into spool after making the socket of spool bottom aim at crankshaft structure, crankshaft structure is fallen in the socket of spool; And the bottom of spool is provided with the spool briquetting, and when the turning handle body, the crankshaft structure of handle body is depressed the spool briquetting, drives the sealing mouth of the downward sealed valve body of spool, thereby drainage valve is closed.When opening drainage valve, only need the turning handle body, the crankshaft structure jack-up spool of handle body is got final product.The drainage valve of this structure is when packing spool into, because the width in the spool socket is greater than the cross-sectional diameter of handle body crankshaft structure, and the positioner of crankshaft structure is not set in the socket of spool bottom, so when putting into spool, the spool location is inaccurate, causes the sealing ring of spool to cooperate imprecision with valve interior wall; Particularly when the crankshaft structure of handle body made progress the jack-up spool, spool can not accurately reset and maybe can't reset.
In addition because the taper seat contact area of the sealing ring of spool and valve interior wall is little, so when the hydraulic pressure in the valve body was excessive, the water in the valve body can ooze out along the valve core seal ring edge, water or bubbling phenomenon occur emitting, causes the sealing performance of valve body bad.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, and a kind of drainage valve that can make the spool accurate positioning and easily reset is provided.
Technical solution of the present utility model is, a kind of drainage valve with following structure is provided: it comprises valve body, spool and handle body, and the lateral wall of described spool is provided with the elastic seal ring that matches with the valve interior wall taper surface; Described handle body and valve body are rotatably connected, and the end that handle body is connected with valve body is set to crankshaft structure, when being provided with for the crankshaft structure rotation, the bottom of described spool depresses the spool briquetting of spool, the bottom of described spool also is provided with a socket, the width dimensions of described socket is greater than the diameter dimension of the crankshaft structure of handle body, the spool inwall at described socket top is provided with an arc positioning groove, and the cambered surface size of the cambered surface of described arc positioning groove and the crankshaft structure of handle body matches.
After adopting above structure, a kind of drainage valve of the utility model compared with prior art, have the following advantages: owing on the spool inwall at socket top, spool bottom, be provided with an arc positioning groove, and the cambered surface size of the crankshaft structure of the cambered surface of arc positioning groove and handle body matches.When packing spool into, the arc positioning groove of spool just in time is stuck on the crankshaft structure of handle body, and the installation of spool is played the role of positioning; When crankshaft structure jack-up spool opened water valve, crankshaft structure slided in the arc positioning groove, and spool is resetted accurately.
As a kind of improvement, the inwall taper surface bottom of described valve body is provided with the annular inner groovy that matches with the elastic seal ring of spool, and the maximum gauge of described annular inner groovy is less than the outside dimension of elastic seal ring.When spool is depressed by the crankshaft structure of handle body, the elastic seal ring of spool is pressed in the basifacial annular inner groovy of taper of valve interior wall, and the inwall tight fit of the outer wall of sealing ring and annular inner groovy, increased the contact area of sealing ring and valve interior wall like this, even when the hydraulic pressure in valve body is excessive, water in the valve body can not ooze out along the valve core seal ring edge yet, has so just strengthened the sealing performance of drainage valve.
