Abstract

The utility model relates to a plug valve with different output flow rates. The plug valve with the different output flow rates comprises a valve body, a cone-shaped valve plug, packing, a packing gland and a driving device. The valve body is provided with an oil inlet and an oil outlet, and the oil inlet end and the oil outlet end of the valve body are provided with internal threads. The cone-shaped valve plug is arranged inside an inner cavity of the valve body, the upper portion of the cone-shaped valve plug is pressed tightly by the packing gland, and the packing is arranged between the cone-shaped valve plug and the packing gland, so that not only the oil leakage can be prevented, but also the free rotation of the cone-shaped valve plug can be guaranteed. A large L-shaped flow channel and a small L-shaped flow channel which are distributed symmetrically are arranged inside the cone-shaped valve plug, and two ends of the large L-shaped flow channel and two ends of the small L-shaped flow channel can be respectively communicated with the oil inlet and the oil outlet of the valve body when the cone-shaped valve plug rotates to certain angle under the action of the driving device. The two ends of the small L-shaped flow channel are trumpet-shaped, the bore diameter of the larger end of the small L-shaped flow channel is equal to the bore diameter of the oil inlet and the oil outlet of the valve body, so that the smoothness of the oil flow channels is guaranteed and the resistance is small.

Description

A kind of stopcock that has different output flows
Technical field
The utility model relates to a kind of stopcock of realizing two kinds of different output flows, belongs to the technical field of valve series products.
Background technique
In hydraulic control system, to the executive component fuel feeding, impel actuator movement by hydraulic power, in practical operation, between hydraulic power and executive component, set up valve usually, control the flow size by valve, to realize the different motion speed of executive component.But all kinds of valves that use are difficult to only just accurately control two kinds of different output flows with a valve at present, and then accurately realize two kinds of different motion speed.
The model utility content
The utility model mainly provides a kind of stopcock with two kinds of different output flows.Make conical valve plug rotation by drive unit, small one and large one two " L " shape runner two ends are communicated with filler opening, the oil outlet of valve body respectively, under the constant situation of valve body filler opening place oil pressure, runner by varying in size respectively, the fluid flow difference that stopcock oil outlet place is flowed out, and can guarantee that output flow is accurate.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of stopcock that has different output flows comprises valve body, conical valve plug, Gland, filler, clamping bolt and drive unit, and described valve body is provided with filler opening and oil outlet, and oil inlet end and oil outlet end have internal thread.Described conical valve plug is installed on body cavity, and conical valve portion is beyond the Great Wall compressed by Gland, and filler is arranged between the two, both can prevent oil liquid leakage, has to guarantee that conical valve plug rotates freely.Be provided with small one and large one two " L " shape runners in the described conical valve plug, article two, " L " shape runner is symmetrical distribution, under the drive unit effect, conical valve plug rotates to an angle, and just can realize that size " L " shape runner two is communicated with filler opening and the oil outlet of valve body respectively.Described little " L " shape runner two flare, its large port aperture equates with the filler opening of valve body and the aperture of oil outlet.
Advantage of the present utility model is: valve just can be realized two kinds of different flows outputs, and output flow is accurate, stopcock structure simple, reliable, cost is low, make the life-span long.
Description of drawings
Fig. 1 is complete section structural representation of the present utility model.
Fig. 2 is the sectional structure chart of big " L " shape runner of the present utility model and valve body filler opening and oil outlet connection.
Fig. 3 is the sectional structure chart of little " L " shape runner of the present utility model and valve body filler opening and oil outlet connection.
Wherein: 1. driving handle, 2. driving handle locking nut, 3. packing ring, 4. clamping bolt, 5. Gland, 6. filler, 7. conical valve plug, 8. valve body.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
The utility model such as Fig. 1, Fig. 2, shown in Figure 3, a kind of stopcock that has different output flows comprises valve body 8, and described valve body 8 is provided with filler opening and oil outlet, and oil inlet end and oil outlet end have internal thread, can be connected with extraneous pipeline.
Described conical valve plug 7 is installed on the inner chamber of valve body 8, and conical valve plug 7 tops are compressed by Gland 5, and the filling filler 6 between the two, both can prevent oil liquid leakage, has to guarantee that conical valve plug 7 rotates freely.
Be provided with small one and large one two " L " shape runners in the described conical valve plug 7, article two, " L " shape runner is symmetrical distribution, under the drive unit effect, conical valve plug 7 rotates to an angle, and just can realize that size " L " shape runner two ends are communicated with filler opening and the oil outlet of valve body 8 respectively.
Little " L " shape runner two flare in the described conical valve plug 7, its large port aperture equate with the filler opening of valve body 8 and the aperture of oil outlet, guarantee that liquid flow channel for oil is smooth, and resistance is little.
