Abstract
The invention discloses a cam valve with a check block. The cam valve comprises a cam valve body, a flow guide cavity is formed in the cam valve body in a hollow mode, two pipeline connectors are formed between the flow guide cavity and the outer wall of the cam valve body, the middle of the flow guide cavity is spherical, the two ends of the flow guide cavity are cylindrical and are provided with a first cylindrical cavity and a second cylindrical cavity respectively, and the check block is arranged at the connecting position of the spherical part of the flow guide cavity and the first cylindrical cavity and is parallel to the first cylindrical cavity. Through the mode, the check can help to locate a cut-off valve block, and use is more convenient.
Description
Technical field
The present invention relates to a kind of band block cam valve.
Background technique
Cam valve is one of a kind of conventional precision optical machinery component, general cam valve all adopts cut-off valve piece to control the break-make of pipeline, but described cut-off valve piece is not easy location in rotary course, be easy to cause pipeline not exclusively to close, use very inconvenient.Therefore, existing cam valve can not meet people's demand.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of band block cam valve, and described block can help to locate described cut-off valve piece, uses more convenient.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of band block cam valve is provided, comprise cam valve body, described cam valve body inner hollow forms diversion cavity, between the outer wall of described diversion cavity and described cam valve body, form two pipeline connection ports, described diversion cavity middle part is spherical, described diversion cavity two ends are cylindrical and are designated as respectively the first cylindrical cavity and the second cylindrical cavity, the joint of the spherical part of described diversion cavity and described the first cylindrical cavity is provided with block, and described block and described the first cylindrical cavity are parallel to each other.
In a preferred embodiment of the present invention, described band block cam valve further comprises cut-off valve piece, valve rod and swingle, described cut-off valve piece is fixed on described valve rod, described valve rod one end can be rotatably set in described cam valve inner, and the other end stretches out described cam valve body and is fixedly connected with described swingle.
In a preferred embodiment of the present invention, described cut-off valve piece is sector crosssection spheroid.
In a preferred embodiment of the present invention, described the first cylindrical cavity is provided with the first seal ring near the one end at described diversion cavity middle part.
In a preferred embodiment of the present invention, between described valve rod and described cam valve body, be provided with the second seal ring.
The invention has the beneficial effects as follows: block of the present invention can help to locate described cut-off valve piece, uses more convenient.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the sectional view with block cam valve of the present invention;
Fig. 2 is the composite structure schematic diagram of block of the present invention, valve rod, cut-off valve piece.
In accompanying drawing, the mark of each parts is as follows: 1, cam valve body; 2, diversion cavity; 3, block; 4, cut-off valve piece; 5, valve rod; 6, swingle; 7, the first seal ring; 8, the second seal ring.
Embodiment
To the technological scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 to Fig. 2, the embodiment of the present invention comprises:
A kind of band block cam valve, comprise cam valve body 1, described cam valve body 1 inner hollow forms diversion cavity 2, between described diversion cavity 2 and the outer wall of described cam valve body 1, form two pipeline connection ports, described diversion cavity 2 middle parts are spherical, described diversion cavity 2 two ends are cylindrical and are designated as respectively the first cylindrical cavity and the second cylindrical cavity, and the joint of the spherical part of described diversion cavity 2 and described the first cylindrical cavity is provided with block 3, and described block 3 is parallel to each other with described the first cylindrical cavity.
Described band block cam valve further comprises cut-off valve piece 4, valve rod 5 and swingle 6, described cut-off valve piece 4 is fixed on described valve rod 5, described valve rod 5 one end can be rotatably set in described cam valve body 1 inside, and the other end stretches out described cam valve body 1 and is fixedly connected with described swingle 6.
Described cut-off valve piece 4 is sector crosssection spheroid.
Described the first cylindrical cavity is provided with the first seal ring 7 near the one end at described diversion cavity 2 middle parts.
Between described valve rod 5 and described cam valve body 1, be provided with the second seal ring 8.
During use, when needs cutting out pipeline, described cut-off valve piece 4 rotates until described block 3 blocks described cut-off valve piece 4, and now, described cut-off valve piece 4 is just in time blocked pipeline.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
