Abstract
The utility model discloses a simple manual two-position three-way reversing valve, which overcomes the defect that the traditional like product is troublesome in reversing operation. The simple manual two-position three-way reversing valve comprise a valve body and a valve rod, wherein the surface of the valve body is provided with an air exhaust interface, the side face of the valve body is provided with an outer threading connector provided with a central hole, the valve cavity port of the valve body is spirally connected with a connecting sleeve, the outer side port of the connecting sleeve is provided with a pressure port, and the inner side port of the connecting sleeve is provided with a necking sealing sleeve which is smaller than the sealing cavity in the middle of the valve cavity in diameter; the valve rod is sequentially provided with a handle, a sealing ring I and a sealing ring II; the handle is provided with an air passage in the center, and two ends of the air passage are respectively provided with a vertical hole and an air exhaust port R; and a spring is arranged between the sealing ring I and the inner side end face of the connecting sleeve. The utility model can be used for realizing direction reversing only by pressing the handle, and an initial state can be recovered after the handle is released, therefore, the utility model can meet application requirements of a petrochemical industry, heating ventilating and air conditioning, a food industry, mechanical processing and other industries which always need reversing operations in short time.
Description
Technical field
The utility model relates to a kind of hand-operated direction valve product manufacturing technology, especially refers to the commutation and the resetting structure technology of two-bit triplet selector valve.
Background technique
Hand-operated direction valve is a kind of comparatively common gas-liquid transmission control unit, be widely used in fields such as boats and ships heavy industry, petrochemical industry, electrical circuitry equipment, medical equipment, industrial furnace, drying equipment, fire-protection equipment, Heating,Ventilating and Air Conditioning (HVAC), cleaning equipment, electro dipping, food industry, vacuum line, water factory's siphonic system, of many uses.This type of typical product as State Intellectual Property Office in notice of authorization on January 30th, 2008, it is the utility model patent of ZL200720067896.0 that name is called " a kind of hand-operated direction valve " patent No., it " comprise valve body; be installed in the protecgulum and the bonnet on both sides before and after the valve body; and the Spool assembly that valve inner is set; be arranged on the protecgulum and the actuating valve core assembly in the handle of valve core movement; described handle drives the valve core assembly by hinge axis and pin; have the twice annular seal groove on the described hinge axis, be with seal ring on the circular groove, be with the sealing slip ring on the seal ring.The tapped hole of described valve body one end main aperture for matching with the electromagnet that is threaded." but in part required turn around time of short application places, using this series products needs Joystick just can finish commutation, and more complicated is processed in its valve hole part manufacturing in addition.For this reason, people expect to invent a kind of easy manually two-bit triplet selector valve product, to satisfy the often sector application demand of needs short time commutation operation such as petrochemical industry, Heating,Ventilating and Air Conditioning (HVAC), food industry, machining.
The model utility content
The technical problems to be solved in the utility model is to overcome existing like product commutation and reset all to need Joystick just can finish, commutate operation trouble and spool to make the deficiency and the defective of processing difficulties, to society provide a kind of can automatically reset manual simplified two-bit triplet selector valve product, to satisfy the often sector application demand of needs short time commutation operation such as petrochemical industry, Heating,Ventilating and Air Conditioning (HVAC), food industry, machining.
The technological scheme that its technical problem that solves the utility model adopts is: manual simplified two-bit triplet selector valve comprises valve body and valve rod, described valve body surface is provided with exhaust port A, described side of valve body is provided with the male connection of tool center hole, the valve pocket port of described valve body is connected with connecting sleeve, the outside port of described connecting sleeve is provided with pressure interface P, inboard port is provided with the reducing stuffing box gland, and described reducing stuffing box gland diameter is less than the Seal cage diameter at described valve pocket middle part; Described valve rod is provided with handle, seal ring one and seal ring two successively; The handle of described valve rod stretches out in described male connection by described center hole; The external diameter of described seal ring one and seal ring two is corresponding with described Seal cage, reducing stuffing box gland internal diameter respectively; The handle of described valve rod is provided with air flue, and the two ends of described air flue are respectively equipped with upright opening and exhaust port R; Be provided with spring between described seal ring one and the described connecting sleeve inner side end.
The outer round surface of described seal ring one and seal ring two is embedded with seal ring one and seal ring two respectively.
The manual simplified two-bit triplet selector valve of the utility model, only need be during commutation by active handle, seal ring two on the valve rod breaks away from sealing state with the reducing stuffing box gland passage is opened, seal ring one is then closed automatically with the Seal cage passage, this moment, pressure interface P was via reducing stuffing box gland, valve pocket, finally was communicated to exhaust port A; After loosing one's grip, this product automatically resets to initial state again.Compare than existing product, have features simple structure, with low cost, advantage that synchronism is good, can satisfy the often sector application demand of needs short time commutation operation such as petrochemical industry, Heating,Ventilating and Air Conditioning (HVAC), food industry, machining.
Description of drawings
Fig. 1 is the utility model product structure schematic representation.
Embodiment
As shown in Figure 1, the manual simplified two-bit triplet selector valve of the utility model, the valve body 1 and the valve rod 17 that places described valve pocket 15 that comprise tool valve pocket 15, described valve body 1 surface is provided with exhaust port A, the port of described valve pocket 15 is connected with connecting sleeve 4, the outside port of described connecting sleeve 4 is provided with pressure interface P, inboard port is provided with reducing stuffing box gland 10, and described reducing stuffing box gland 10 diameters are less than Seal cage 9 diameters at described valve pocket 15 middle parts; The side of described valve body 1 is provided with the male connection 3 of tool center hole 16, and described male connection 3 is connected with hexagonal nut 2 is installed; Described valve rod 17 is provided with handle 5, seal ring 1 and seal ring 2 11 from left to right successively, and the outer round surface of described seal ring 1 and seal ring 2 11 is embedded with seal ring 1 and seal ring 2 13 respectively; The handle 5 of described valve rod 17 stretches out in described male connection 3 by described center hole 16; The external diameter of described seal ring 1 and seal ring 2 11 is corresponding with described Seal cage 9, reducing stuffing box gland 10 internal diameters respectively; The handle 5 of described valve rod 17 is provided with air flue 12, and the two ends of described air flue 12 are respectively equipped with upright opening 6 and exhaust port R; Be provided with spring 14 between described seal ring 1 and the described connecting sleeve 4 inboard ports.
