Description
Technical field：
The invention belongs to supply equipment technical field, more particularly, to a kind of throttle device.
Background technology：
It is water-saving, full name using water wisely.China is the country of a freshwater resources skewness, in daily life, we
As soon as water wring is leading, water continuously flows out, the crisis of possible at all imperceptible water.But in fact, some ground of China
Area is in serious water shortage state, and the water that we depend on for existence, also positive increasingly in short supply.At present, the whole world also has more than 10
Hundred million population does not use clean water, also, the mankind have 3,100,000 people diseased and dead because drinking impure water every year.Therefore use
It is particularly important that water-saving pipeline and equipment, in daily life, often due to current and hydraulic pressure is excessive causes water waste, i.e.
When in water pipe cross-sectional flow area it is certain in the case of, hydraulic pressure is excessive at this time, then water flow be pressurized, so often exceed
The traffic demand of people's daily water consumption, carries out causing water resource waste.
The content of the invention：
The technical problems to be solved by the invention are：There is provided one kind can be according to hydraulic pressure automatic current limiting, to realize water-saving purpose
Throttle device.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：A kind of throttle device, including
Water pipe main body, limiting block, connecting rod, current limliting face, spring and regulation cock, the water pipe main body both ends are respectively arranged with entrance connecting pin
With outlet connecting pin, the outlet connecting pin of the water pipe main body, which is integrally formed, sets current limiting face, and the current limliting face is internally formed
Current limliting chamber, the cross-sectional area of the current limliting chamber linearly successively decrease from entrance connecting pin to outlet connecting pin, and the limiting block is set
For with the matched frustum structure of current limliting chamber shape, and the limiting block is placed in current limliting intracavitary, upper and lower the two of the current limliting face
End symmetrically offers mounting hole, and described connecting rod one end is placed in mounting hole, and the connecting rod other end is fixedly mounted in limiting block,
The spring is placed in mounting hole, the regulation cock by helicitic texture be installed on installation outer end of hole, one end of the spring with
Connecting rod is fixedly connected, and the other end of the spring is against on regulation cock.
Preferably, the water pipe main body is also connected with water tank by pipeline, the pipe between water tank and the water pipe main body
Pressure check valve is provided with road.
Preferably, the angle of inclination in the current limliting face is arranged to 25 °~40 °.
Preferably, the seamed edge of the limiting block and connecting rod close to outlet connecting pin side is disposed as rounded structure.
Compared with prior art, usefulness of the present invention is：This equipment can be adjusted according to the hydraulic pressure difference of flow,
Water flow in pipeline is in a stable numerical value all the time, carry out playing water-saving purpose.When water flow is larger in pipeline,
The pressure that water flow produces at this time overcomes the elastic force of spring to act on promotion limiting block to the movement of current limliting intracavitary, due to water velocity
It hurry up, but the through-flow space of current limliting chamber is small, therefore play throttling action.When water flow is smaller in pipeline, spring gram at this time
The effect for taking current generation promotes limiting block to moving outside current limliting chamber, since the through-flow space of current limliting chamber is big and water hinders
It is small, even if water speed at this time is slower, stable current can be also kept in pipeline.
Brief description of the drawings：
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the present invention.
Embodiment：
Below in conjunction with the accompanying drawings and embodiment the present invention will be described in detail：
A kind of throttle device as shown in Figure 1, including water pipe main body 1, limiting block 2, connecting rod 3, current limliting face 4, spring 6 and tune
Bolt 9 is saved, 1 both ends of water pipe main body are respectively arranged with entrance connecting pin 11 and outlet connecting pin 12, and the water pipe main body 1 goes out
Mouth connecting pin 12, which is integrally formed, sets current limiting face 4, and the current limliting face 4 is internally formed current limliting chamber 41, the horizontal stroke of the current limliting chamber 41
Sectional area linearly successively decreases from entrance connecting pin 11 to outlet connecting pin 12, and the limiting block 2 is arranged to and 41 shape of current limliting chamber
Matched frustum structure, and the limiting block 2 is placed in current limliting chamber 41, and the upper/lower terminal in the current limliting face 4 symmetrically opens up
There is mounting hole 5, described 3 one end of connecting rod is placed in mounting hole 5, and 3 other end of connecting rod is fixedly mounted in limiting block 2, described
Spring 6 is placed in mounting hole 5, and the regulation cock 9 is installed on 5 outer end of mounting hole by helicitic texture, one end of the spring 6 with
Connecting rod 3 is fixedly connected, and the other end of the spring 6 is against on regulation cock 9, and the initial position of connecting rod 3 is adjusted by regulation cock 9,
1 flow of water pipe main body is preset.
In practical applications, when water flow pressure is especially big, the elastic force of hydraulic pressure meeting client spring 6, causes in water pipe main body 1
Flow becomes especially small, therefore to avoid this phenomenon from occurring, the water pipe main body 1 is also connected with water tank 7 by pipeline, described
Pressure check valve 8 is provided with pipeline between water tank 7 and water pipe main body 1, so, when water flow pressure is especially big, one
Part hydraulic pressure can carry out pressure release by pressure check valve 8 and water tank 7, and then ensure the stability of water flow in water pipe main body 1.
As the angle of inclination that is preferably provided with current limliting face 4, the angle of inclination in the current limliting face 4 is arranged to 25 °~40 °.
In addition, in order to reduce the inhibition of limiting block 2 and connecting rod 3 to current, current are avoided to produce vortex phenomenon, it is described
The seamed edge of limiting block 2 and connecting rod 3 close to outlet 12 side of connecting pin is disposed as rounded structure.
It is emphasized that：It is obvious to a person skilled in the art that the invention is not restricted to above-mentioned one exemplary embodiment
Details, and without departing from the spirit or essential characteristics of the present invention, can realize this in other specific forms
Invention.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, the present invention
