Abstract
The utility model relates to a multifunctional decompressor. The multifunctional decompressor comprises a reducing valve. The multifunctional decompressor is characterized in that the reducing valve is inverted, channel openings of an inlet channel and an outlet channel of a reducing valve body are arranged horizontally and upwards and extend vertically and upwards to form a stop valve body of an integrated structure, a valve deck and a pressing cap are connected on the top of the stop valve body, a stop valve clack assembly is arranged inside the stop valve body, a stop valve clack is matched with the channel openings of the reducing valve body for controlling connection and disconnection of the reducing valve, and a connector extending horizontally and outwards is arranged on the end portion of the stop valve body. The multifunctional decompressor has the advantages that functions of the reducing valve and the stop valve are integrated, integration degree is high, structure is compact, installation and maintenance are convenient, time and labor are saved, connection ports are reduced, a leakage probability is lowered, operation is safe and reliable, occupied space of valve bodies is small, and a system pipeline is shortened.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of multifunctional decompression device that has the cut-out gas channel and drain pressure-reducing function.
Background technique
In gas delivery system, the import of reduction valve and outlet end are connected with respectively the stop valve that shields, and when needs cut off the passage of reduction valve one or both sides in the gas delivery system, realize closing by closing stop valve.Reduction valve and stop valve are individual components, need to be connected with system pipeline respectively, and linking route is longer, take up space large, and fitting operation is loaded down with trivial details, wastes time and energy, and the system pipeline contact is many, increases the probability that leakage occurs, and affects the reliability of system.
Summary of the invention
The purpose of this utility model is to provide the multifunctional decompression device that a kind of volume is little, safe and reliable, have the decompression of draining and control channel switching.
Technical solution of the present utility model is: a kind of multifunctional decompression device, comprise reduction valve, it is characterized in that inverted reduction valve, its reducing valve body arranges up into and out of the passway level of passage, extend vertically upward at the place, passway, form the checking-valve body of integrative-structure, the checking-valve body top is connected with valve gap and pressure cap, be provided with cut-off flap assembly in it, the cut-off flap matches with the reducing valve body passway, the break-make of control reduction valve, the end of checking-valve body is provided with the outward extending joint of level.
The joint centerline of two stop valves is on same level.
Joint at one or two stop valve is equipped with gauge table.
The multifunctional decompression device that the utility model provides, by the appropriate design to valve body structure, a reduction valve and two stop valves have been realized in valve body, forming, simultaneously valve body can the one-step casting moulding, between valve and the valve without Assembly interface, improved the reliability of decompressor, integrated decompressor takes up space little, and is easy for installation.
Characteristics of the present utility model are: integrate reduction valve and stop valve function, integrated degree is high, compact structure, and installation and maintenance are convenient, time saving and energy saving, reduced connection interface, reduce the probability that leakage occurs, safe and reliable to operation, valve body takes up space little, has shortened system pipeline.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, the reduction valve of multifunctional decompression device is inverted and is arranged, the top of reducing valve body 25 is connected with Pressure relief valve seat 11, junction between the two is provided with seal ring 24, the decompression flap assembly that is positioned at reducing valve body is made of decompression flap 12 and thimble 20, decompression flap assembly one end is against on the Pressure relief valve seat, and the other end is against on the elastomer diaphragm 22.Be provided with seal ring 23,21 at decompression flap and Pressure relief valve seat, valve body into and out of the through hole of passage.The bottom of reducing valve body is provided with rubber diaphragm 22, and is connected with decompression valve gap 16.The pressure-relief valve spring control unit be by the upper and lower positioning seat 15 that is arranged on the spring 17 of decompression in the valve gap, both ends of the spring, 18 and adjusting screw 19 consist of.Reducing valve body arranges up into and out of passway 26 levels of passage, and extend vertically upward at the place, passway, forms the checking-valve body 27 of integrative-structure, and the checking-valve body top is connected with break valve cover 3, is provided with seal ring 10 between the two, and connects by Female connector fittings 2.The top of break valve cover is connected with Gland 5, and filler and filler damage 9 tops that are arranged on break valve cover by pressure.It is to be made of cut-off valve rod 4 and cut-off flap 13 that cut-off flap assembly is set in the checking-valve body, connects by nut 14 between the two.The cut-off flap matches with the reducing valve body passway, the break-make of control reduction valve.Being positioned at stop valve outer handwheel 6 is connected with the cut-off valve rod by nut 7, pad 8.The level that the end of checking-valve body the is provided with integrative-structure joint 1 that stretches out, the joint centerline of two stop valves is on same level, a joint is the import of decompressor, and another is the outlet of decompressor, in the joint of two stop valves gauge table 28 is installed.
Claims (3)
