Abstract
The utility model relates to a ring-shaped float-controlled valve, which can control the water level balance. A connecting rod 2 is in clearance fit with and connected with a ring-shaped floater 1 in the radial direction; a needle valve 3 is connected onto the connecting rod 2 through a needle valve pin shaft 9; the needle valve 3 and the connecting rod 2 can rotate relatively; and the needle valve 3 can move relatively to a needle valve body 8 in the axial direction. The needle valve body 8 is connected with a fixing screw 4 through screw threads formed on the inner side of the needle valve body 8; the fixing screw 4 penetrates through a certain case cover board; and then the whole ring-shaped needle valve is fixed through a fixing nut 5 and a fixing gasket 6. A rubber valve seat 7 is in interference fit with the fixing screw 4. The whole valve body adopts a hollow structure so as to be connected with a waterway. The ring-shaped floater 1 and the needle valve 3 can rotate relatively to the connecting rod, so that the ring-shaped floater 1 can rotate in multiple directions without limit. The distance between the rubber valve seat 7 and the needle valve 3 can be adjusted through the threaded connection length between the fixing screw 4 and the needle valve body 8 without replacing the ring-shaped floater 1, that is, the flow rate of the ring-shaped float-controlled valve can be adjusted.
Description
Technical field
The utility model relates to a kind of float-controlled valve, specifically, is the annular float valve about the control water level balance.
Background technique
Usually adopt two kinds of needle-valve and ball valves during the flow of existing float-controlled valve control water.The general valve seat orifice size of needle-valve is less, and flow is also less; Ball valve then flow is bigger.But both have common characteristics, promptly mostly are flow and fix, and are unadjustable.
Summary of the invention
The purpose of this utility model is that to overcome existing noticeable degree water flow bigger than normal or less than normal, and the immutable shortcoming of water flow, designs a kind of intermediate flow that is applicable to, and the adjustable within the specific limits annular float valve of flow.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: the annular float valve is made up of valve body and annular float two-part.The bottom of this float-controlled valve is the float of an annular, float a connecting rod radially only is set, can any direction regulate the fluctuation of the water surface.Whole valve body rides on connecting rod, and valve body top is fixed on certain casing by screw rod and nut.
Valve body all is a hollow structure, for connecting the water route.Annular float and valve body can rotate with respect to connecting rod, and annular float just can carry out multidirectional rotation and not be restricted like this.Under the situation that annular float is not changed, can adjust the size that distance between rubber valve seat and the needle valve body is adjusted water flow by the position of adjusting screw rod.
The beneficial effects of the utility model are: the size in valve body hollow aperture can be adjusted according to the actual flow size, simultaneously, under the definite situation in valve body hollow aperture, can adjust the size of water flow by the distance between adjustment rubber valve seat and the needle valve body, Applicable scope is very wide.
Description of drawings
The three-dimensional sectional view of Fig. 1 annular float valve.Fig. 2 annular float valve 3-D view.
1. annular floats among the figure, 2. float connecting rod, 3. needle-valve, 4. standing screw, 5. set screw nut, 6. retaining washer, 7. rubber valve seat, 8. needle valve body, 9. needle-valve bearing pin.
Embodiment
Determine the size in valve body hollow aperture according to actual needs, and valve body is fixed on certain box cover.In conjunction with Fig. 1 and Fig. 2 specific embodiments and the utility model are done and to be described in further detail:
Connecting rod 2 Spielpassung are connected in annular float 1 radially, and needle-valve 3 is connected on the connecting rod 2 by needle-valve bearing pin 9, can relatively rotate between needle-valve 3 and the connecting rod 2, and needle-valve 3 can move axially with respect to needle valve body 8.Needle valve body 8 links to each other with standing screw 4 by its inside thread, and standing screw 4 passes certain box cover, with set screw nut 5 and retaining washer 6 the full annular needle-valve is fixed then.Rubber valve seat 7 interference are on standing screw 4.
The change of annular float 1 suffered buoyancy is big, and needle-valve 3 will be blocked rubber valve seat 7 along axially the moving up of needle valve body 8, and the distortion of the big more rubber valve seat 7 of buoyancy is just big more, and sealing is just good more; Otherwise potential drop is low when the equilibrirm water, when the suffered buoyancy of annular float diminishes gradually, needle-valve 3 will axially moving down along needle valve body 8, the amplitude of opening along with the variation rubber valve seat that moves down displacement also can change, thereby regulates the variation of flow, changes the speed of water level balance.
Because annular float 1 is connected with needle-valve bearing pin 9 by connecting rod 2, the needle-valve bearing pin 9 that connecting rod 2 can cast-over valve 3 rotates, and annular float 1 also can rotate around connecting rod 2, and annular float can carry out multidirectional rotation and not be restricted like this.
Simultaneously, can adjust distance between rubber valve seat 7 and the needle-valve 3, also just adjust the flow size of this annular float valve by adjusting the length that is threaded between standing screw 4 and the needle valve body 8.
Claims (5)
1. annular float valve that is used for the control water level balance, it is characterized in that: this device is made up of valve body and annular float two-part, annular float a connecting rod radially is set, valve body rides on the connecting rod of annular float, valve body top is fixed on certain casing by screw rod and nut; Valve body all is a hollow structure, for connecting the water route; Annular float and valve body can rotate with respect to connecting rod, and like this, annular float just can carry out multidirectional rotation and not be restricted; Under the situation that annular float is not changed, can adjust distance between rubber valve seat and the needle-valve by adjusting the length that is threaded between standing screw and the needle valve body, also just adjusted the flow size of this annular float valve.
2. annular float valve according to claim 1 is characterized in that: annular float a connecting rod radially only is set, can any direction regulate the fluctuation of the water surface.
3. annular float valve according to claim 1 is characterized in that: the valve seat of needle-valve adopts rubber valve seat, can adjust the size of flow under the condition of the different distortion degree of different buoyancy and rubber.
4. annular float valve according to claim 1 is characterized in that: can further adjust the size that distance between rubber valve seat and the needle valve body is adjusted flow by the position of adjusting screw rod.
5. annular float valve according to claim 1 is characterized in that: the size in the aperture of hollow valve body can be adjusted, to adapt to the needs of different flow.
