Description
Technical field
The utility model relates to a kind of hand-operated direction valve product manufacturing technology, refers to that especially commutation drives and the resetting structure technology.
Background technique
Hand-operated direction valve is a kind of comparatively common gas-liquid transmission control unit, its purposes is quite extensive, is 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.This type of relatively typical product as State Intellectual Property Office in notice of authorization on June 10th, 2009, it is the utility model patent technology of ZL200820126012.9 that name is called " two six logical hand-operated direction valves " patent No., it comprises " valve body; be arranged in the valve body with and spool that matches with valve interior wall and the operating grip that is connected with spool; be formed with the oil inlet P that all is communicated with on the valve body; oil return inlet T; first couple of actuator port A1; B1 and second couple of actuator port A2 with valve inner, B2, when operating grip drive spool is in first working position, oil inlet P is communicated with oil outlet A1 and oil outlet A2, and oil return inlet T is communicated with return opening B1 and return opening B2; When operating grip drive spool was in second working position, oil inlet P was communicated with oil outlet A1, and oil return inlet T all is communicated with return opening B1 and the actuator port A2, B2." but this product inside is not provided with resetting means; so in actual application; when gas-liquid pressure is higher; have resistance between nested seal ring in valve rod outer ring and the valve interior wall in addition;, have a strong impact on the proper functioning of gas-liquid transmission control unit so be easy to generate the stuck or blunt phenomenon that resets of valve rod during commutation.
The model utility content
The technical problems to be solved in the utility model is that valve rod easily is stuck or resets blunt deficiency and defective when overcoming existing like product commutation, the manual multidigit selector valve product that provides a kind of inner tool to reset power assisting device, the agility that resets, easy operation to society is used required to satisfy various fields such as boats and ships heavy industry, petrochemical industry, medical equipment, food industry.
The technological scheme that its technical problem that solves the utility model adopts is: manually the multidigit selector valve comprises valve body and valve rod; Described valve body perisporium is provided with a plurality of interfaces, is provided with the annular pass corresponding to the valve interior wall of described interface, and described valve rod is provided with the multiple tracks annular cavity; One side of described valve body is fixed with protecgulum, and described preceding cover cavity is provided with the slide block that is connected with described valve rod; Described front cover surface is fixed with block, and described block is movably hinged with reversing bar, and described reversing bar lower end and described slide block flexibly connect; The opposite side of described valve body is fixed with tail-hood, and described valve rod is arranged with left spring seat and right spring seat near an end of described tail-hood, is provided with spring between described left spring seat and the right spring seat.
Described shoe surface is provided with conical pilot hole, and described reversing bar lower end is provided with spheroid and is inserted into described conical pilot hole.
Described reversing bar upper end is provided with handle.
The manual multidigit selector valve of the utility model product, end at the close tail-hood of valve rod is arranged with power assistant spring, when carrying out switch operation, because spring can play the effect of auxiliary reset power-assisted, so can improve the agility that commutation resets greatly, effectively prevent the generation of valve rod stuck phenomenon, also improved hand-operated direction valve product functional reliability.Compare than existing product, have features simple structure, with low cost, advantage that synchronism is good, can be widely used in various fields such as boats and ships heavy industry, petrochemical industry, medical equipment, food industry.
Description of drawings
Fig. 1 is the utility model product structure schematic representation.
Embodiment
As shown in Figure 1, the manual multidigit selector valve of the utility model, comprise valve body 6 and place the valve rod 7 of described valve body 6 inner chambers, described valve body 6 perisporiums are provided with a plurality of interfaces such as interface A, interface B, interface R1, interface R2 and interface P, are provided with annular pass 9 corresponding to valve body 6 inwalls of described each interface; Described valve rod 7 is provided with multiple tracks annular cavity 8, is provided with seal ring 10 between the adjacent described annular cavity 8; The conducting of described annular pass 9 and described annular cavity 8 with close the existing conventional, well-known technology that belongs to the gas-liquid transmission, repeated description no longer in present patent application.
There is tail-hood 1 in the left side of described valve body 6 by screw, described valve rod 7 is arranged with a pair of left spring seat 2, right spring seat 4 near an end of described tail-hood 1, be provided with spring 3 between described left spring seat 2, the right spring seat 4, the outside of described left spring seat 2 is subjected to the jump ring 5 of support fixation in described valve rod 7 tail ends.
There is protecgulum 11 on the right side of described valve body 6 by screw, and described protecgulum 11 inner chambers are provided with the slide block 14 that is connected with described valve rod 7 heads by pin 12, and described slide block 14 surfaces are provided with conical pilot hole 19; Described protecgulum 11 surfaces are fixed with block 15, and described block 15 is movably hinged with reversing bar 17 by pin 16; Described reversing bar 17 upper ends are provided with handle 18, and described reversing bar 17 lower ends are provided with spheroid 13 and are inserted into described conical pilot hole 19.
Continue in conjunction with the accompanying drawings the working principle of summary the utility model product below.With state shown in Figure 1 is example, when reversing bar 17 places the vertical position, and all not conductings mutually between interface A, interface B, interface R1, interface R2 and the interface P; After reversing bar 17 was pulled to the right, valve rod 7 was moved to the left, this moment interface A and interface R1, interface B and two pipeline conductings of interface P, interface R2 closure; Otherwise after reversing bar 17 was pulled left, valve rod 7 moved right, interface A and interface P, interface B and two pipeline conductings of interface R2, interface R1 closure.When using the utility model product to carry out switch operation, because valve rod 7 tail ends are provided with spring 3 and can play the auxiliary reset power-assisted, so can improve the agility that commutation resets greatly, prevent the generation of valve rod stuck phenomenon, effectively improve hand-operated direction valve product functional reliability.
