Abstract
The utility model relates to a current-limiting stop valve which comprises a valve body. The valve body comprises a current-limiting portion and a stop portion, the stop portion comprises a stop valve and a stop cavity, and the stop valve is connected with the valve body and is located on the upper portion of the stop cavity; the current-limiting portion comprises a current-limiting cavity and a current-limiting valve which is arranged in the current-limiting cavity, a throttling opening is formed in the front portion of the current-limiting cavity, the inner diameter of the throttling opening is smaller than the inner diameter of the current-limiting cavity, and a trapezoid table which is arranged at the front end of the current-limiting valve can be embedded into the throttling opening to close the throttling opening. The current-limiting stop valve has the advantages that the current-limiting stop valve is composed of a throttling valve and a stop valve, is a novel combined valve which integrates current limiting and stopping, and is a device which automatically limits current and cuts off fluid; and the current-limiting stop valve controls flow of the fluid by changing the size of an overflowing section, reduces the size of a valve set to a maximum extent, is small in size, simplifies structural design and is convenient to produce, operate and maintain.
Description
Technical field
The utility model relates to a kind of current limliting stop valve.
Background technique
Popularize along with industrialized, a process pipelines then needs to install at pipeline the valve of difference in functionality not to realize that independent technological requirement is purpose, owing to be subjected to the influence of body size, causes valve group length to increase, and influences the process pipelines requirement.The current limliting stop valve of my company's development in one, greatly reduces the size of valve body with two kinds of valve combination.
The model utility content
The utility model proposes a kind of current limliting stop valve, the function of existing limited flow has the function of cutting off fluid again, has remedied deficiency of the prior art.
The technical solution of the utility model is achieved in that
A kind of current limliting stop valve comprises valve body, and described valve body comprises restrictor and by portion, the described portion that ends comprises shutoff valve and by the chamber, described shutoff valve is connected with described valve body and is positioned at described by the top, chamber; Described restrictor comprises current limliting chamber and the current limliting valve that places in the described current limliting chamber, and front portion, described current limliting chamber is provided with internal diameter less than the restriction of current limliting chamber internal diameter, and the bucking ladder that described flow-limiting valve is held in front of the door can embed in the described restriction and close restriction.
The beneficial effects of the utility model are: the utility model is made up of flow-limiting valve and stop valve two-part, is current limliting and by be the novel combination brake switch and proporting of one, is the device of automatically limiting flow and cut-out fluid; The utility model relies on the size that changes overflow section, controls the flow of fluid; Maximum limit reduces the valve packet size, and volume is little, and is simple in structure, is convenient to production operation and maintenance.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the described a kind of current limliting stop valve of the utility model embodiment;
Among the figure:
1, valve body; 2, current limliting chamber; 3, current limliting valve; 4, shutoff valve; 5, by the chamber; 6, restriction.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the described current limliting stop valve of the utility model embodiment comprises valve body 1, and described valve body 1 comprises restrictor and the portion of ending, the described portion that ends comprises shutoff valve 4 and by chamber 5, described shutoff valve 4 is connected with described valve body 1 and is positioned at described by 5 tops, chamber; Described restrictor comprises current limliting chamber 2 and the current limliting valve 3 that places in the described current limliting chamber 2, and 2 front portions, described current limliting chamber are provided with internal diameter less than the restriction 6 of current limliting chamber 2 internal diameters, and the bucking ladder of described current limliting valve 3 front ends can embed in the described restriction 6 and close restriction 6.
Current limliting stop valve of the present utility model is under certain pressure difference, relies on the size of the liquid resistance that changes restriction, comes the flow of control orifice.Be applicable to the pipeline of control flow.When flow is big, cut off flow.Do not having under the situation of ABAP Adapter, realizing that automatically flow cuts off.Control is sensitive, debug easy, long service life.
The utility model is made up of flow-limiting valve and stop valve two-part, is current limliting and by be the novel combination brake switch and proporting of one, is the device of automatically limiting flow and cut-out fluid; The utility model relies on the size that changes overflow section, controls the flow of fluid; Maximum limit reduces the valve packet size, and volume is little, and is simple in structure, is convenient to production operation and maintenance.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
