Description of the invention (丨) [Technical field to which the invention belongs] The present invention relates to a uniform opening valve used in fire sprinkler equipment or fire extinguishing equipment such as foam fire extinguishing equipment. [Known technology] Fire extinguishing equipment using a conventional open valve is installed in a place where a hot-air stream has expanded before the closed-type sprinkler, such as a parking lot, even if a closed-type sprinkler is installed. In a fire, once the gasoline in the car is ignited, the fire instantly expands and burns, or it is a building with a ceiling high. Take the fire extinguishing equipment installed in the above building as an example. 'It is to extinguish the fire by spraying liquid to the protective area at the same time after sensing the fire. Therefore, the fire equipment is equipped with a uniform opening valve and an open sprinkler.' Taking one open valve used in the fire extinguishing equipment as an example, there is one open valve described in Japanese Patent Publication No. 64-39763 and Japanese Patent Publication No. 64-42064 as shown in FIG. 1. The above-mentioned one-piece open valve is divided into 3 chambers by a valve body 102 and a diaphragm 11, and is divided into an inlet 106 of the primary side of the one-piece open valve, a secondary side 112 of the one-piece open valve, and Back 104 of the piston 103. The water introduced from the inlet 106 flows into the back 104 through the check valve 108, and flows into the sensing pipe 109 connected to the back 104. A test valve that is normally closed is set on the end of the sensing piping 109, and the inside of the sensing piping 109 and the back 104 are filled with water supplied by a uniform opening valve ---------:- ------- Order -------- 1 (Please read the notes on the back before filling in this page) This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) 1 497977 A7 _______ 5. Description of the invention (〆) The valve body 102 is closed in structure by the pressure of the water filled in the back 104 and the force of the compression spring 114 so that the water does not flow to the secondary side 112 〇 Above The uniform opening valve is caused by the movement of the sensing head connected to the sensing pipe 109 to cause the water in the back 104 to flow out, and the valve body 102 is opened due to the decrease in the water pressure. Sprinklers are used to extinguish fire. However, when garbage is blocked in the flow path of the above-mentioned one-off valve, the one-off valve must be disassembled to remove the waste. At this time, the valve body of the on-off valve 113 on the primary side of the collective opening valve is closed so that water is not supplied to the collective opening valve, and then the test valve on the end of the sensing pipe 109 is opened, and the sensing pipe 109 and the back are discharged. Water within 104. Most of the garbage clogging occurs at the inflow port of the through hole 107 and the check valve 108 where the flow path becomes narrow. Therefore, the check valve 108 'is configured to be removable, so that the garbage can be easily removed. In addition, the fire extinguishing equipment has the obligation to check regularly in order to fully function at any time in the event of a fire. Therefore, the secondary side of the open valve must be tested so that it can still be tested without supplying water to the open sprinkler. Measures for valve action. Specifically, a piping between the open valve and the open sprinkler head is provided with the same on-off valve 113 as before, and the switch valve 113 is closed during testing so that water does not flow into the piping connected to the open sprinkler head. [Problem to be solved by the invention] However, in the case of one of the above-mentioned open valves, if the on-off valve is set to 5 paper sizes, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applicable. ------ ---: ------------ Order · ------- I (Please read the notes on the back before filling out this page) 497977 A7 ___B7___ V.

In recent years, buildings have been designed to minimize the installation space for fire-fighting piping or air-conditioning piping, etc. The above-mentioned on-off valves are also required to be miniaturized without occupying the installation space. The installation place is narrow 'Therefore, the cover of the check valve is disassembled, the internal valve body and the compression spring are removed, and then the operation of removing the garbage in the through hole is quite troublesome, and it is required to raise the efficiency of the operation. Therefore, an object of the present invention is to provide a unified open valve which does not take up installation space, is small in size, light in weight, inexpensive, and has good maintainability when the garbage is clogged. [Means to solve the problem] In order to achieve the above-mentioned purpose, the invention of item 1 of the scope of patent application is a Qi valve used in one of the fire extinguishing equipment. The butterfly valve is embedded in one body, and the flange side end of the sheet of the butterfly valve protrudes from the flange surface. Because the aforementioned butterfly valve is embedded in a unified opening valve, there is no need to provide on-off valves on the primary side and the secondary side of the collective opening valve as is conventional, which can improve the working efficiency and reduce the burden on the operator. As a result, no space is required for installing the on-off valve. In addition, since the butterfly valve has a simple structure, it can be buried in a unified open valve with fewer parts and lower costs than ball valves and gate valves. In addition, on the above sheet, if the flange side end of the uniform opening valve is provided with 6 paper sizes, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applicable. &Quot; '~ 497977 A7 __B7____ 5 2.

As a result, the pressure of the fluid in the primary side exceeds the force and pressure of the compression spring 26 in the control chamber 23, causing the piston valve 21 to move upward, and the fluid flows into the secondary side and spreads water from the open type connected to the secondary side piping. Sprinkle the first 9 liquids to extinguish the fire. In order to test the operation of the open valve 1 at the same time, the butterfly valve 30 'provided on the secondary side 4 is closed first, the screw plug 37 provided on the secondary side is removed, and a drain pipe is installed. When the test valve 38 is opened (located at the end of the piping 18 mounted on the sensor head 17), the pressure in the control chamber 23 is lowered and becomes the same state as when the sensor head 17 is activated. The pressure drop in the control room 23 causes the piston valve 21 to move upward, and the fire extinguishing fluid flows into the secondary side 4. However, since the butterfly valve 30 'provided on the secondary side 4 is closed, the fire extinguishing fluid will not flow into the installation. The piping 10 on the open sprinkler head 9 and the fire extinguishing fluid will flow to the pre-set drain pipe.

Description of the invention (\) Close the butterfly valve 30 installed on the primary side to prevent the fire extinguishing fluid from flowing into the open valve 1 together. In addition, if the through hole A or the holes 49 and 50 leading to the check valve are blocked by the garbage, the screw plug 40 and the cover member 12 are screwed together, so the screw plug 40 can be easily removed from the cover member 12, Trash clogging the holes inside the plug 40 can be removed away from the place where a full open valve is provided. Although one of the above-mentioned uniform opening valves is of a piston type, the butterfly valve of the present invention can also be provided in the diaphragm-type uniform opening valve disclosed in Sho 63-3579. [Effects of the Invention] As explained above, since the butterfly valve is embedded in the Qi open valve in one aspect of the present invention, it occupies less installation space, is lighter in weight, and has a simpler structure than a ball valve or a gate valve. , And the price is low. In addition, during construction, it is conventionally necessary to install a uniform opening valve and a butterfly valve on each piping, but if one of the above-mentioned uniform opening valves is used, the operation of the butterfly valve is not provided, so the operation is convenient, and no butterfly is required. In the case of a butterfly valve, it can be used without the butterfly valve after removing the valve body of the butterfly valve. In addition, a maintenance-free valve system is also considered in one aspect of the present invention. Since a check valve that can flow from the primary side of the universal-open valve to the control room is installed inside the plug that can be disassembled, the flow When the entrance is clogged with trash, the trash can be removed with the plugs removed from the collective opening valve.
