Abstract
The utility model discloses a cutting ferrule joint with a throttle function. The cutting ferrule joint comprises a joint body, wherein the joint body is provided with a first connecting end connected with an oil passage pipeline, a second connecting end connected with a hydraulic execution element, and a central hole for communicating the oil passage pipeline and the hydraulic execution element, the aperture d of the central hole is 0.5-0.8 mm, and a length-diameter ratio d/1 is not less than 4 and not more than 10. According to the utility model, the structure is improved on the basis of the original cutting ferrule joint, so that the throttle characteristic of the central hole of the cutting ferrule joint is utilized, a fixed throttle is formed between the oil passage pipeline and the hydraulic execution element, so that speed of action of the execution element is adjusted; and the cutting ferrule joint has the characteristics of low cost, easiness in popularization and good fixation and throttle effects.
Description
Technical field
The utility model relates to the hydraulic element field, relates to a kind of hydraulic pressure cutting ferrule joint with fixed restriction effect in particular.
Background technique
The cutting ferrule joint is as in the hydraulic system, and between connecting pipeline and the hydraulic actuator or the transition element between pipeline and the pipeline, itself only plays the transition interconnect function.On the basis that does not change pump displacement, if will regulate, just must carry out current limliting to the flow that flows to executive component hydraulic oil to the action speed of hydraulic actuator, so must in hydraulic system, increase throttle valve.Common throttle valve of the prior art is such as being used in the board-like throttle valve on the multi-way control valve and being used in the tubular type throttle valve in the pipeline; To increase the cost of hydraulic system greatly like this, and make hydraulic system become more complicated.
In use simultaneously, the oil seal character amount of throttle valve affects the working stability of whole hydraulic system, if the throttle valve leakage of oil then will make it lose restriction effect, and cause hydraulic system to break down.So one group of control unit of every increase in the hydraulic system; The working stability of hydraulic system will threaten by how potential portion; Because after throttle valve was set up for the speed control of hydraulic actuator action, the through-current capacity of throttle valve must remain unchanged, so throttle valve just is equivalent to the fixed restriction device.Consider the throttle valve structure, all have adjustable handle, can't guarantee after use a period of time that adjustable handle is fully loosening, thereby have influence on the service behaviour of restriction effect and whole hydraulic system.
In view of this, the inventor has this case to produce to the above-mentioned defective further investigation of present throttle valve then.
The model utility content
The purpose of the utility model is to provide a kind of cutting ferrule joint with throttling function, exists leakage of oil hidden danger and adjustable handle to have loosening hidden danger to solve throttle valve, and finally has influence on the problem of restriction effect and whole hydraulic work system performance.
In order to reach above-mentioned purpose, the solution of the utility model is:
A kind of cutting ferrule joint with throttling function; Wherein, Comprise joint body; The center hole that this joint body has first connecting end that can link to each other with oil line pipe, second connecting end that can link to each other with hydraulic actuator and is communicated with oil line pipe and hydraulic actuator, this center hole aperture d is 0.5～0.8mm, slenderness ratio is 4≤l/d≤10.
Further, this first connecting end and second connecting end are the outside thread connecting end.
After adopting said structure; But the cutting ferrule joint winding that the utility model relates to is between oil line pipe and hydraulic actuator; Thereby be used for replacing throttle valve, it does not increase under the situation of any new hydraulic element in hydraulic system, utilizes the restriction characteristic of the center hole of cutting ferrule joint; Hydraulic fluid flow rate to the cutting ferrule joint of flowing through carries out fixed restriction control; Thereby realize the adjusting to hydraulic actuator action speed, in addition, that model utility also has is simple in structure, cost is low and the characteristics being convenient to promote.
Description of drawings
The perspective view of Fig. 1 a kind of cutting ferrule joint for the utility model relates to;
Fig. 2 is the sectional view of Fig. 1.
Among the figure:
Joint body 1 first connecting end 11
Second connecting end, 12 center holes 13.
Embodiment
In order further to explain the technological scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
As depicted in figs. 1 and 2; A kind of cutting ferrule joint 100 that the utility model relates to throttling function, it comprises joint body 1, this joint body 1 has first connecting end 11, second connecting end 12 and center hole 13; This first connecting end 11 is used for linking to each other with oil line pipe; This second connecting end 12 is used for linking to each other with hydraulic actuator, and this center hole 13 is communicated with oil line pipe and hydraulic actuator, and the aperture d of this center hole 13 is 0.5～0.8mm; Slenderness ratio is 4≤l/d≤10, and slenderness ratio promptly refers to the length of center hole 13 and the ratio of diameter.Particularly, this first connecting end 11 and second connecting end 12 are the outside thread connecting end, thereby can link to each other with the internal thread of oil line pipe and hydraulic actuator.
Like this, utilize the restriction characteristic of the center hole 13 of cutting ferrule joint 100, between oil line pipe and hydraulic actuator, formed a fixed restriction device, thereby realize adjusting executive component action speed.
The utility model has following beneficial effect at least:
One, the utility model can carry out structure modify on the basis of original cutting ferrule joint 100; Make it have the fixed restriction function; Also take into account original cutting ferrule joint 100 simultaneously and be used for the excessively effect of connection, so it need not to increase any additional parts, plays the effect of simplifying oil circuit;
Two, the utility model utilizes its restriction characteristic through adopting short and small center hole 13, makes cutting ferrule joint 100 in hydraulic system, serve as the fixed restriction device, and it is effective that it has fixed restriction, takes into account sealing, simple characteristics; It can change the through-flow pore size of throttle orifice, and also solve hydraulic element oil seal problem according to the needs of actual executive component speed simultaneously;
Three, cost is low, is easy to promote, and need not increase new element in the hydraulic system, only needs when producing cutting ferrule joint 100, and the aperture size size that through-flow center hole 13 processing cost model utilitys are actual required can become the cutting ferrule joint 100 with throttling function.
Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
