Abstract
The utility model relates to a clamp butterfly valve with a rubber-coated valve plate. The clamp butterfly valve comprises an operating handle, a stop dial, an actuator, a valve body and the valve plate. The operating handle is connected with one end of the actuator. The stop dial is fitted to one side of the actuator. The other end of the actuator is connected with the valve body. Two ends of the valve body are provided with circular grooves respectively. The valve plate is movably fitted inside the valve body. The middle of the valve plate is axially provided with a valve shaft sleeve. A valve shaft is nested inside the valve shaft sleeve. The valve shaft sleeve is radially provided with a pin hole. A rubber layer is fixed to the outer surface of a body of the valve plate. The rubber layer is fixed to the outer surface of the valve plate of the clamp butterfly valve, so that the valve plate can contact with the valve body directly with no need for mounting a valve seat on the valve plate; the clamp butterfly valve is simple in structure, convenient to produce and fine in tightness; the service life of the clamp butterfly valve is prolonged; mounting steps are simplified, and production cost is reduced.
Description
Technical field
The utility model belongs to valve technology field, relates to valve plate, especially a kind of butterfly valve of the clip with rubber-covered valve plate.
Background technique
The clamp band type pipeline connects and has been widely used in the fluid conveying engineerings such as plumbing, fire-fighting, ventilation.Current clip butterfly valve of take the groove type clip Connecting format is integrated type, and valve body and trench portions are an integral body, are actually on the basis of former flange-type butterfly valve, change flange into groove type clip, the needs that connect to adapt to the clamp band type pipeline.The clip butterfly valve generally consists of valve body and valve plate, possess a rotating shaft on valve plate, the valve plate rotating shaft is installed in the rotary shaft hole of valve body valve rod, and an end of rotating shaft is protruding from the rotary shaft hole of valve body, and control the valve plate rotation by a drive unit, thereby control the switching of butterfly valve.Butterfly valve body contacts with the valve seat of valve plate, due to by valve base sealing, easily cause that valve operation moment is excessive, the valve plate wearing and tearing in using process, not only wasted human and material resources, and can only guarantee the low pressure seal effect, this has brought inconvenience to the use of clip butterfly valve.
The model utility content
The purpose of this utility model is to overcome the deficiency of original technology, and a kind of reasonable in design, the butterfly valve of the clip with rubber-covered valve plate with low cost, easy to use are provided.
The technological scheme that the utility model technical solution problem adopts is:
A kind of butterfly valve of the clip with rubber-covered valve plate, comprise opening-closing handle, stop dial, actuator, valve body and valve plate, described opening-closing handle is connected with an end of actuator, described stop dial is installed on a side of actuator, the other end of actuator is connected with valve body, the two ends of described valve body are shaped with respectively annular groove, and described valve plate is movably installed in valve body; On described valve plate, middle part is shaped with the valve shaft cover vertically, suit valve shaft in the valve shaft cover, and valve shaft puts and radially is shaped with pin hole, and described valve plate plate body outer surface is fixedly mounted with a rubber layer.
And described rubber layer is the ethylene-propylene diene copolymer rubber layer.
And the height of the ethylene-propylene diene copolymer rubber layer of described valve shaft cover head portion and bottom part outer surface is greater than the height of the ethylene-propylene diene copolymer rubber layer of valve shaft cover intermediate portion.
Advantage of the present utility model and good effect are:
1, the valve plate outer surface of the utility model clip butterfly valve is fixedly mounted with a rubber layer, thereby this valve plate can directly be contacted with valve body, and do not need to install again valve seat on valve plate, simple in structure, easy to make, good airproof performance not only, extended the working life of clip butterfly valve, and simplified the step of installing, reduced cost of production.
2, the height of the rubber layer of the valve shaft of valve plate of the present utility model cover head portion and bottom part outer surface is greater than the height of the rubber layer of valve shaft cover intermediate portion, because the two ends up and down of the valve shaft of valve plate cover directly contact with valve plate and are rotated, thereby produce friction, strengthen like this this valve plate intensity in use, further improved the working life of this clip butterfly valve.
The accompanying drawing explanation
Fig. 1 is structural front view of the present utility model;
The left view that Fig. 2 is Fig. 1;
The plan view that Fig. 3 is Fig. 1;
The A-A that Fig. 4 is Fig. 1 is to cross-sectional view.
Embodiment:
For further understanding content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.It should be noted that, the present embodiment is descriptive, is not determinate, can not limit thus protection domain of the present utility model.
A kind of butterfly valve of the clip with rubber-covered valve plate, comprise opening-closing handle 1, stop dial 2, actuator 3, valve body 4 and valve plate 5, described opening-closing handle is connected with an end of actuator, described stop dial is installed on a side of actuator, the other end of actuator is connected with valve body, the two ends of described valve body are shaped with respectively annular groove 8, and described valve plate is movably installed in valve body; On described valve plate, middle part is shaped with valve shaft cover 7 vertically, suit valve shaft 10 in the valve shaft cover, and valve shaft puts and radially is shaped with pin hole 6.
Innovative point of the present utility model is:
(1) described valve plate plate body outer surface is fixedly mounted with a rubber layer 9, the ethylene-propylene diene copolymer rubber layer can be vulcanized to valve plate, and described rubber layer can be the ethylene-propylene diene copolymer rubber layer.This encapsulate butterfly valve plate can directly contact with valve body, and does not need to install on valve plate valve seat again, not only simple in structure, easy to make, has improved working life, and has simplified the step of installing, and has reduced cost of production.
(2) the height of the ethylene-propylene diene copolymer rubber layer of described valve shaft cover head portion and bottom part outer surface is greater than the height of the ethylene-propylene diene copolymer rubber layer of valve shaft cover intermediate portion.Because the two ends up and down of the valve shaft of valve plate cover directly contact with valve plate and are rotated, thereby generation rubs, and has strengthened like this this valve plate intensity in use, has further improved its working life.
Claims (3)
1. the butterfly valve of the clip with rubber-covered valve plate, comprise opening-closing handle, stop dial, actuator, valve body and valve plate, described opening-closing handle is connected with an end of actuator, described stop dial is installed on a side of actuator, the other end of actuator is connected with valve body, the two ends of described valve body are shaped with respectively annular groove, and described valve plate is movably installed in valve body; On described valve plate, middle part is shaped with the valve shaft cover vertically, suit valve shaft in the valve shaft cover, and valve shaft puts and radially is shaped with pin hole, it is characterized in that: described valve plate plate body outer surface is fixedly mounted with a rubber layer.
