Abstract
A double-seat water seal butterfly valve relates to a butterfly valve and includes a valve body, a valve rod, butterfly plates, valve seats and a driving device, wherein the butterfly plate is mounted on the valve body through the valve rod, the valve rod is connected with the driving device, a water inlet is formed at the top part of the valve body, and a water outlet is formed at the bottom part of the valve body. The utility model is characterized in that the valve seats are fixed in the grooves of the butterfly plates and the valve body through a pressure plate, two butterfly plates and the valve seats are respectively arranged on two sides of the valve body, and the two butterfly plates, the two valve seats and the valve body form a closed water-seal inner cavity. A support is arranged between the valve body and the driving device, and two ends of the support are connected with the valve body and the driving device. The driving device adopts an electric device. The utility model has the benefits that the double-seat water seal butterfly valve is structured by adopting the two parallel butterfly plates and the two valve seats among which pressure water is filled, achieving double sealing guarantee and good sealing performance.
Description
Technical field
The utility model relates to butterfly valve, specifically is a kind of bivalve seat Water seal butterfly valve.
Background technique
Butterfly valve is with a kind of valve of opening about disc type open-shut device reciprocating rotating 90 degree, cut out with the regulated fluid passage.Butterfly valve is not only simple in structure, volume is little, in light weight but also driving moment is little, easy and simple to handle, rapid, and can have good flow regulating function simultaneously and close sealing characteristics.And butterfly valve application the earliest is an air quantity controllable register on flue or the chimney, also be used for low service systems such as ventilation or air feed, to be widely used in the water-feeding ﹠ drainaging pipeline system of industries such as electric power, waterpower, metallurgy, chemical industry, urban construction, also be used for gas pipeline now.
Traditional water seal valve seat comprises valve body, butterfly plate, O-ring seal and valve rod, valve seat with sphere shape is housed in the valve body, bottom and top at valve body are respectively equipped with water inlet and water outlet, butterfly plate is contained on the valve body by upper valve rod and lower valve rod, at last lower valve rod two ends the stuffing box packing assembly is housed respectively, two seal rings are fixed on by pressing plate in the aprons slot of butterfly plate, and valve seat and butterfly plate and two seals cushion rubber form the water seal chamber of sealing.But the butterfly valve of this structure butterfly plate in opening-closing process rotates the extruding valve seat, and mechanical wear, scratch and the bad phenomenon of sealability easily take place between valve plate and the valve seat.
The model utility content
The technical problem that the utility model solved is to provide the little bivalve seat Water seal butterfly valve of mechanical wear in a kind of good sealing effect, simple to operate, the using process.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of bivalve seat Water seal butterfly valve, constitute by valve body, valve rod, butterfly plate, valve seat and drive unit, butterfly plate is installed on the valve body by valve rod, valve rod links to each other with drive unit, top at valve body is provided with water intake, and the bottom of valve body is provided with drain opening, it is characterized in that: described valve seat is fixed in the groove of butterfly plate and valve body by pressing plate, be respectively arranged with two butterfly plates and valve seat in the both sides of described valve body, two butterfly plates and two valve seats and valve body constitute the water seal inner chamber of sealing.
Be provided with support between described valve body and drive unit, the support two ends are connected with drive unit with valve body respectively.
Described drive unit is an Electric actuator.
The beneficial effects of the utility model are to adopt parallel double butterfly plate and bivalve seat structure, between be full of press water, constitute double seal guarantee, good seal performance with valve seal is secondary.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the lateral plan of Fig. 1.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As depicted in figs. 1 and 2, a kind of bivalve seat Water seal butterfly valve, by valve body 1, valve rod 2, butterfly plate 3, valve seat 4 and drive unit 5 constitute, butterfly plate 3 is installed on the both sides of valve body 1 respectively by valve rod 2, valve rod 2 links to each other with drive unit 5, drive unit 5 is an Electric actuator, be shaped on water intake 6 at the top of valve body 1, the bottom of valve body 1 is shaped on drain opening 7, in the butterfly plate 3 of valve body 1 both sides and the valve body groove fixedly the time, fix two valve seats 4 by pressing plate, the both sides of valve body 1 are respectively arranged with the water seal inner chamber that two butterfly plates 3 and 4, two butterfly plates 3 of two valve seats and two valve seats 4 and valve body 1 constitute sealing like this.5 mounting brackets 8 of valve body 1 and drive unit, support 8 two ends are connected with drive unit 5 with valve body 1 respectively.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
