Abstract
A novel abrasion resistance butterfly valve comprises a valve body, a valve plate, a valve cover, a wrench, a butterfly plate and a valve shaft. The butterfly plate is mounted inside the valve body through the valve shaft, the upper end of the valve body is fixedly provided with the valve cover, the upper end of the valve cover is fixedly provided with the wrench, the upper end and the lower end of the inner side of the valve body are respectively provided with an abrasion resistance block, wherein the abrasion resistance block fixed at the upper end of the inner side of the valve body is connected with a downward-pressing spring, and the abrasion resistance block fixed at the lower end of the inner side of the valve body is connected with an upward-pressing spring. The novel abrasion resistance butterfly valve has the advantages that when the abrasion resistance blocks are abraded, the springs can push the abrasion blocks to move towards the butterfly plate, and leakage caused by abrasion is avoided.
Description
Technical field
The utility model relates to valve field, particularly a kind of butterfly valve.
Background technique
The center butterfly valve is compared with eccentric-butterfly-valve, has advantage light, simple in structure, that be convenient to install.But center dish version is the valve body serious wear at two ends up and down, and because friction is large, causes the large problem of resistance that opens and closes.
Summary of the invention
The purpose of this utility model is in order to address the above problem, to have designed a kind of novel wear resistant butterfly valve.The specific design scheme is:
A kind of novel wear resistant butterfly valve, comprise valve body, valve plate, valve gap, spanner, butterfly plate, valve shaft, described butterfly plate is installed in the described valve body by valve shaft, the upper end of described valve body is fixed with valve gap, the upper end of described valve gap is fixed with spanner, the up and down two ends of described valve body inboard are equipped with wear-resistant block, and the wear-resistant block that wherein is fixed in the valve body inner top side is connected with lower pressing spring, and the wear-resistant block that is fixed in the valve body inside lower end is connected with pressing spring.
One end of described lower pressing spring is connected with described wear-resistant block, and the described valve gap of the other end connects.
One end of described upper pressing spring links to each other with described wear-resistant block, and the other end links to each other with described valve body.
Described lower pressing spring, upper pressing spring all are in compressive state.
Be provided with the sealing packed layer between described valve body and the described wear-resistant block.
Described spanner lower end is provided with limiting board, and described limiting board and described valve gap connect.
Connected the novel wear resistant butterfly valve that above-mentioned mode of execution of the present utility model obtains, its beneficial effect is:
The up and down two ends of described valve body inboard are equipped with wear-resistant block, and the wear-resistant block that wherein is fixed in the valve body inner top side is connected with lower pressing spring, and the wear-resistant block that is fixed in the valve body inside lower end is connected with pressing spring.When wear-resistant block was worn, described spring can promote described wear-resistant block and move to the butterfly plate direction, prevents the leakage that causes because of wearing and tearing.

A kind of novel wear resistant butterfly valve, comprise valve body 1, valve gap 3, spanner 4, butterfly plate 5, valve shaft 6, described butterfly plate 5 is installed in the described valve body 1 by valve shaft 6, the upper end of described valve body 1 is fixed with valve gap 3, the upper end of described valve gap 3 is fixed with spanner 4, it is characterized in that, the up and down two ends of described valve body 1 inboard are equipped with wear-resistant block 7, the wear-resistant block 7 that wherein is fixed in valve body 1 inner top side is connected with lower pressing spring 8, and the wear-resistant block 7 that is fixed in valve body 1 inside lower end is connected with pressing spring 9.
One end of described lower pressing spring 8 is connected with described wear-resistant block 7, and the described valve gap 3 of the other end connects.
One end of described upper pressing spring 9 links to each other with described wear-resistant block 7, and the other end links to each other with described valve body 1.
Described lower pressing spring 8, upper pressing spring 9 all are in compressive state.
Be provided with sealing packed layer 10 between described valve body 1 and the described wear-resistant block 7.
Described spanner 4 lower ends are provided with limiting board 2, and described limiting board 2 is connected with described valve gap 3.
After valve used a period of time, described wear-resistant block 7 can wear and tear, and at this moment described upper pressing spring 9, lower pressing spring 8 make respectively described wear-resistant block 7 move to described butterfly plate 5 directions, increase seal.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; some changes that those skilled in the art may make some part have wherein all embodied principle of the present utility model, belong within the protection domain of the present utility model.
