Abstract
The utility model discloses a sealable throttling valve. The sealable throttling valve comprises a valve body, an adjusting screw rod, a throttling ring and a ball arc block, wherein the valve body comprises a water inlet hole, a ball hole, a valve core hole and a water outlet which are sequentially communicated; the adjusting screw rod and the throttling ring are inserted in the valve core hole; the adjusting screw rod is capable of axially rotating; the throttling ring is sleeved with the adjusting screw rod; the ball arc block is mounted in the ball hole in a fitting mode; the inner end face of the ball arc block is fixedly connected to the adjusting screw rod; and the arc surface of the ball arc block is sealed with the water outlet in a fitting mode. The sealable throttling valve has the function of a ball valve and is low in cost.
Description
Technical field
The utility model belongs to a kind of valve field, is specifically related to a kind of sealable throttle valve.
Background technique
Traditional throttle valve all has the spool with pressure controlling, while needing the liquid in valve body, can only a ball valve or other switches be installed on throttle valve water intake in addition, so not only complex structure, and also cost is high.
Model utility content
(1) technical problem that will solve
The problem that will solve of the present utility model is to make throttle valve cost.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of sealable throttle valve, comprises valve body, adjusting screw rod, restrictor ring and ball arc piece; Described valve body includes water inlet, ball hole, spool bore and water outlet; Described water inlet, ball hole, spool bore and water outlet are communicated with successively; Described adjusting screw rod and restrictor ring are all plugged in spool bore, wherein adjusting screw rod can axial-rotation, described restrictor ring is socketed on adjusting screw rod, described ball arc piece cooperation is arranged in ball hole, the interior edge face of its ball arc piece is fixedly connected with adjusting screw rod, the arc surface of its ball arc piece and water outlet fitted seal.
The arc surface of described ball arc piece is provided with a seal ring; Between described ball hole and water inlet, seal by seal ring.
The interior edge face of described ball arc piece is provided with a socket; The top of described adjusting screw rod is provided with a cutting, and described cutting is plugged in socket.
The material of described ball arc piece is stainless steel.
Described adjusting screw rod material is also stainless steel.
(3) beneficial effect
Throttle valve of the present utility model, by a ball arc piece is set at the top of adjusting screw rod, makes ball arc piece block water inlet by rotation, thereby intercepts, and forms switching function, without ball valve switch is set, has therefore reduced cost.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The sealable throttle valve of one as shown in Figure 1-Figure 3, comprises valve body 1, adjusting screw rod 2, restrictor ring 3 and ball arc piece 4; Described valve body 1 includes water inlet 5, ball hole 6, spool bore 7 and water outlet 8; Described water inlet 5, ball hole 6, spool bore 7 and water outlet 8 are communicated with successively; Described adjusting screw rod 2 is all plugged in spool bore 7 with restrictor ring 3, wherein adjusting screw rod 2 can axial-rotation, described restrictor ring 3 is socketed on adjusting screw rod 2, and described ball arc piece 4 cooperations are arranged in ball hole 6, and the interior edge face of its ball arc piece 4 is fixedly connected with adjusting screw rod 2, thereby drive ball arc piece 4 axial-rotations by adjusting screw rod 2, make arc surface and water outlet 5 fitted seal of its ball arc piece 4, stop up thereby form, realize the function of switch, without ball valve switch is set, reduce cost.
The arc surface of described ball arc piece 4 is provided with a seal ring 9; Between described ball hole 6 and water inlet 5, seal by seal ring.Thereby enhancing sealing effect.
The interior edge face of described ball arc piece 4 is provided with a socket 10; The top of described adjusting screw rod 4 is provided with a cutting 11, and described cutting 11 is plugged on socket 10, thereby drives ball arc piece 4 to rotate.
The material of described ball arc piece 4 is stainless steel.
Described adjusting screw rod 2 materials are also stainless steel.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
