Abstract
The utility model discloses a self-sealing energy-saving stop valve, which comprises a left valve body and a right valve body, and a valve plate integrally combined by a left, a middle and a right sealed sheets via a positioning pin is arranged between the two valve bodies. The top end of the middle sealed sheet is fixedly connected with a connecting buckle, two ends of the connecting buckle are connected with a handle via the left valve body and the right valve body, and flow holes in the left and the right sealed sheets are refracted flow holes arranged at one side. The left and the right sealed sheets are fixed in the valve body, and the flow holes are staggered. The middle sealed sheet is an annular sheet, the center of the middle sealed sheet is provided with an isolation zone used for dividing the middle sealed sheet into two flow holes, the middle sealed sheet can rotate 90 DEG around a shaft pin, and the left valve body and the right valve body are provided with 90 DEG arched notches in order to cause two ends of the connecting buckle connected with the handle to slide along the arched notches to obtain the aim of opening or closing the valve. The handle can be wrenched to directly rotate the sealed sheets, the conversion time of an intermediate transmission form is saved, and the aim of fast opening and closing the valve is obtained. The utility model is particularly suitable for the pipelines of steam, chemical engineering, fire protection, etc. The valve can be used for regulating flow freely.
Description
(1) technical field: the utility model relates to a kind of valve, relates in particular to a kind of energy-conservation stop valve of a kind of selfsealings of using on hot-water heating, chemical industry, fire-fighting, the oil and gas pipes of being used for.
(2) background technique: at present, the common valve that is used on civilian hot-water heating or the industrial production pipeline mainly comprises two big classes, one class is to have valve body, the spool that is used for shutoff valve body chamber fluid passage, the screw mandrel that is connected as a single entity with spool combines, spool has spheroid, side's body, opening of valve, the pass makes the spool obstruction or leaves the fluid passage realization of valve body chamber by the lifting or the rotation of screw mandrel, when valve closing, the spool of two kinds of forms all will contact with the valve body face seal, because the frequent switch of valve, make the often friction and cause the damage of valve pocket of spool and valve body surface of contact, pressure medium will go out from the surface current of wearing and tearing, and then along its screw mandrel outflow, the race of often saying in the industrial production that Here it is, emit, drip, leak phenomenon, cause the waste of medium.Owing to appearring in the wearing and tearing of valve, dangerous situation cause irremediable loss to happen occasionally in the industrial production.Another kind of then is gate valve, and this gate valve structure comprises valve body substantially, valve seat, flashboard, valve rod, valve gap, operation piece, Sealing.Closing and opening of two big class valves all leans on the lifting or the rotation of valve rod to realize, and the lifting of valve rod or rotation are the realizations that relatively rotates by operating grip rotating screw bolt and nut, so, the opening ways that this armrest handle rotates uses the little valve of volume all right on the tubule road, but when using for large-scale gas-liquid pipeline, because type of belt drive conversion, switching path is long, use inconvenient, particularly the incident for burst takes place, as fire, pipe leakage needs to open water supply line rapidly or to close leakage pipe, and the mode of this handle with sleeve by middle transmission can not satisfy the requirement of closing pipeline valve rapidly.
(3) summary of the invention: in order to overcome unlatching or the slow shortcoming of closing velocity that present gas-liquid pipeline valve exists, the utility model provides a kind of energy-conservation stop valve of selfsealings that can satisfy quick open and close requirement.
The technical solution of the utility model realizes in the following manner: the energy-conservation stop valve of a kind of selfsealings, it comprises valve body, intercepting flashboard in the valve body, the sealing gasket of sealed valve body and intercepting flashboard, wherein valve body is by left valve barrel, the valve body that right valve barrel is combined into one, intercepting flashboard between two valve bodies is by a left side, in, right three diaphragm seals are combined integrated by a locating stud, in diaphragm seal fixedly connected with connecing to detain, connecing the end of thread head is connected with handle through valve body, a left side, right diaphragm seal is provided with the bias current hole by a side, a left side, right diaphragm seal is fixed in the valve body and discharge orifice interlocks, middle diaphragm seal is a ring segment, middle diaphragm seal center is established an isolation zone it is divided into two discharge orifices, in diaphragm seal can rotate 90 ° around pivot pin, on valve body, have 90 ° of arc notch so that the end of thread head that connects that is connected with handle slides along arc notch and reaches the purpose of unlatching or throttle down.
Connecing button fixedlys connected with middle diaphragm seal by middle positioning screwn.
Right valve barrel is enclosed within the left valve barrel and by the silk pressing cover and fixes.
Connecing the button two ends sees through left and right valve body, is connected with handle by screw.
On left valve barrel, have 90 ° of arc notch so that a termination reaches unlatching or throttle down along the arc notch slip purpose is buckled in connecing of being connected with handle.
On left and right valve body, have 90 ° of arc notch so that two ends reaches unlatching or throttle down along the arc notch slip purpose is buckled in connecing of being connected with handle.
Between left and right diaphragm seal and left and right valve body, be fixed with left and right sealing gasket respectively.
The left, center, right diaphragm seal is the sealed ceramic sheet.
Good effect of the present utility model is: 1, by pulling handle, direct rotary seal sheet, saved the time of middle type of belt drive conversion, reached the purpose of quick open and close valve, be specially adapted to use on the pipelines such as steam that the burst accident risks takes place, chemical industry, fire-fighting.2, this valve also as required regulating handle from 0 ° to 90 °, from open for a short time, half-open, open greatly, standard-sized sheet regulates flow arbitrarily, this valve can be pacified as required and is low in and high out, but resource is saved in also high in and low out, avoids waste.3, good seal performance, the setting of left, center, right diaphragm seal and the setting of left and right sealing gasket make the pipeline medium valve be in which kind of state and can not enter in the valve cavity, therefore can not leak.Diaphragm seal adopts 95 potteries, has effectively prolonged the working life of valve; 4, dismounting is easy to maintenance, and each parts is all detachably changed, and has avoided a place to damage the consequence that integral body is scrapped.
