Abstract
The utility model relates to a block check valve which comprises a valve body. The valve body comprises a block part and a check part, wherein the block part comprises a block valve and a block cavity, the block valve is connected with the block valve body and is located above the block cavity, the check part comprises a spring, a valve clack and a check cavity, the spring and the valve clack are arranged in the check cavity, and one end of the spring is connected with the valve clack. The block check valve has the advantages that the block check valve is composed of the block valve and the check valve and is a novel combination valve integrated the check valve and the block valve, is a device for preventing backflow and cutting off, and is suited to be mounted perpendicularly and horizontally. By means of the block check valve, the size of a valve bank is decreased furthest, the size of block check valve is small, the physical structure of the block check valve is simplified, automation level is improved, and the block check valve is convenient to produce, operate and maintain.
Description
Technical field
The utility model relates to a kind of safety check that blocks.
Background technique
In the manufacturing process, for realizing process function, same process pipelines need be installed different valves.Cause institute's mounted valve quantity many, installation dimension is big, has increased cost, and maintenance maintenance is also inconvenient.The development of my company block safety check, two kinds of valve combination in one, in the time of existing check function, are had cutting action again, not only realized the purpose of a valve multipotency, greatly reduce the size of valve body again.
The model utility content
The utility model proposes a kind of safety check that blocks, the function of existing non-return has the function of cut-out again, has remedied deficiency of the prior art.
The technical solution of the utility model is achieved in that
A kind of safety check that blocks comprises valve body, and described valve body comprises the portion of blocking and non-return portion, and the described portion of blocking comprises cut-off valve and block the chamber, and described cut-off valve is connected with described valve body and is positioned at described blocking above the chamber; Described non-return portion comprises spring, flap and check cavity, and described spring and described flap place in the described check cavity, and described spring one end is connected with described flap.
Described cut-off valve is provided with seal ring.
The beneficial effects of the utility model are: the utility model is made up of block valve and safety check two-part, be non-return and be cut to the novel combination brake switch and proporting of one that the function of existing non-return has the function of cut-out again, be the device of anti-backflow and cut-out, can be suitable for vertical simultaneously and the level installation.Maximum limit reduces the valve packet size, and volume is little, and the simplified structure design improves automatization level, 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 described a kind of structural representation that blocks safety check of the utility model embodiment;
Among the figure:
1, valve body; 2, cut-off valve; 3, block the chamber; 4, spring; 5, flap; 6, check cavity; 7, seal ring.
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 safety check that blocks of the utility model embodiment comprises valve body 1, and described valve body 1 comprises the portion of blocking and non-return portion, the described portion of blocking comprises cut-off valve 2 and blocks chamber 3, and described cut-off valve 2 is connected with described valve body 1 and is positioned at described 3 tops, chamber of blocking; Described non-return portion comprises spring 4, flap 5 and check cavity 6, and described spring 4 and described flap 5 place in the described check cavity 6, and described spring 4 one ends are connected with described flap 5; Described cut-off valve 2 is provided with seal ring 7.
The utility model is made up of block valve and safety check two-part, is non-return and is cut to the novel combination brake switch and proporting of one, and the function of existing non-return has the function of cut-out again, is the device of anti-backflow and cut-out, can be suitable for vertical simultaneously and the level installation.Maximum limit reduces the valve packet size, and volume is little, and production operation and maintenance are convenient in the simplified structure design.
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.
