Abstract
The utility model relates to a kind of half nahlock valve, comprise valve body and valve member, valve inner is provided with cylindrical cavity: valve member comprises valve rod, arc block A, arc block B, semicircular ring C, arc block A and arc block B is coaxially arranged on valve rod, arc block A and arc block B is relative to the middle part bisector plane specular of valve body, semicircular ring C is fixed on the cylindrical cavity wall of valve body, and semicircular ring C is between arc block A and arc block B, and the radian of arc block A and arc block B is greater than 180 °; The top of valve body and bottom are provided with water intake and water outlet; The present invention is coordinated by two arc blocks and semicircular ring, realizes opening and closing of water route, while valve when pressure-bearing, the Sealing of valve only bears axial force, does not bear transverse force, improves the sealability of valve, decrease Sealing when pressurized generation deformation, the leakage caused.
Description
Technical field
The present invention relates to a kind of half nahlock valve, belong to valve field.
Background technique
Traditional valve mechanism is complicated, and Sealing is more, and tightness is inadequate, and high pressure is easy to cause leakage.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the technical problem that tightness existing in prior art is inadequate, provide a kind of novel valve.
The technical solution adopted for the present invention to solve the technical problems is: a kind of half nahlock valve, comprise valve body and valve member, described valve inner is provided with cylindrical cavity: described valve member comprises valve rod, arc block A, arc block B, semicircular ring C, described arc block A and arc block B is coaxially arranged on valve rod, described arc block A and arc block B is relative to the middle part bisector plane specular of valve body, described semicircular ring C is fixed on the cylindrical cavity wall of valve body, described semicircular ring C is between arc block A and arc block B, the radian of described arc block A and arc block B is greater than 180 °, the top of described valve body and bottom are provided with water intake and water outlet.
As further innovation of the present invention, between described valve rod and the wall of valve body, be provided with seal ring.
The invention has the beneficial effects as follows: the present invention is coordinated by two arc blocks and semicircular ring, realize opening and closing of water route, valve is when pressure-bearing simultaneously, the Sealing of valve only bears axial force, do not bear transverse force, improve the sealability of valve, decrease Sealing when pressurized generation deformation, the leakage caused.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is generalized section of the present invention.
1 valve body, 2 valve rods, 3 arc block A, 4 semicircular ring C, 5 arc block B, 6 water intakes, 7 water outlets, 8 cylindrical cavities.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, the present invention is a kind of half nahlock valve, comprise valve body 1 and valve member, valve body 1 inside is provided with cylindrical cavity 8: valve member comprises valve rod 2, arc block A3, arc block B5, semicircular ring C4, arc block A3 and arc block B5 is coaxially arranged on valve rod 2, arc block A3 and arc block B5 is relative to the middle part bisector plane specular of valve body 1, semicircular ring C4 is fixed on cylindrical cavity 8 wall of valve body 1, semicircular ring C4 is between arc block A3 and arc block B5, and the radian of arc block A3 and arc block B5 is greater than 180 °; The top of valve body 1 and bottom are provided with water intake 6 and water outlet 7; Seal ring is provided with between the wall of valve rod 2 and valve body 1;
Make arc block A3 by rotary valve rod 2, arc block B5 is with semicircular ring C4 generating portion or overlap completely, thus change the guiding path of valve, realize the change of flow, arc block A3, arc block B5, semicircular ring C4 are under the pressure of current, bear thrust load, a unified axial deformation occurs, and there is not any change in radial direction, thus improve the withstand voltage and sealability of valve.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
