Description
Technical field
The invention belongs to a kind of connection set of fluid line, specifically, relate in particular to a kind of quick kick-off valve.
Background technique
Land fluid assembly and disassembly arm is the equipment that is used for loading and unloading the fluid tank car; Before loading and unloading, must the front end flange of land fluid assembly and disassembly arm be connected and good seal with flange on the tank car; Begin loading and unloading then, loading and unloading must separate land fluid assembly and disassembly arm after accomplishing with tank car.Work when connection, separation is more loaded down with trivial details, and when separating, often has the part dielectric leakage, make troubles to the staff, and befouling environment.The at present external quick kick-off valve of producing of land fluid assembly and disassembly arm has fundamentally solved this problem, but it costs an arm and a leg, several times of whole often land fluid assembly and disassembly arm price; And after sales service is not in place.At present, also there is not a kind ofly can realize that the quick of fluid assembly and disassembly arm and tank car is connected and separates simultaneously cheap quick kick-off valve on the Domestic market.
Summary of the invention
The objective of the invention is for a kind of quick kick-off valve, to solve the quick expensive defective of kick-off valve in the existing technology.
The present invention realizes through following technological scheme:
A kind of quick kick-off valve comprises main end device and secondary end device, and said main end device comprises the first adpting flange body, spool and valve shell, and the external side of first adpting flange is a valve shell, and the inboard is a spool; The first adpting flange body is provided with guide lugs, and valve shell is provided with and the corresponding slide-and-guide groove of guide lugs, and spool is provided with cam gear, and cam gear comprises the cam tommy bar, and the cam plate stem is installed on the first adpting flange body, and the cam plate stem can rotate; The first adpting flange body lower end is provided with SEALING FITTING, is provided with first return spring between the first adpting flange body and the valve shell, and valve shell inside is hinged with hangers through connecting pin; Said secondary end device comprises the set casing and the second adpting flange body, and the set casing and the second adpting flange body interfix through fixing bolt, and secondary end device inside is provided with passive valve rod, is provided with second return spring between the passive valve rod and the second adpting flange body.
Preferably be provided with Packing spring between the first adpting flange body and the SEALING FITTING; Preferably be respectively equipped with seal ring on SEALING FITTING and the passive valve rod.
Compared with prior art, the invention has the beneficial effects as follows: overcome former land fluid assembly and disassembly arm and connected and the troublesome operation of separating, avoided separating the leakage of back fluid, thereby made that operation is more convenient, and effectively prevented the pollution of the environment; Operation, easy to maintenance simple does not need technical training for safety operation.Adopt the cone seal valve to reduce the wearing and tearing of O type sealing, the medium when preventing to load and unload is revealed, is polluted.High circulation and in light weight has been optimized course of conveying, has improved the efficiency of loading and unloading.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further:
In the drawings, 1, the first adpting flange body; 2, valve shell; 3, spool; 4, Packing spring; 5, first return spring; 6, SEALING FITTING; 7, seal ring first; 8, cam plate stem; 9, connecting pin; 10, hangers; 11, passive valve rod; 12, guide lugs; 13, set casing; 14, the second adpting flange body; 15, second return spring; 16, fixing bolt; 17, slide-and-guide groove; 18, handle; 19, seal ring second.
A kind of quick kick-off valve comprises main end device and secondary end device, and said main end device comprises that the first adpting flange body 1, spool 3 and valve shell 2, the first adpting flange bodies 1 outside are valve shell 2, and the inboard is a spool 3; The first adpting flange body 1 is provided with guide lugs 12; Valve shell 2 is provided with and guide lugs 12 corresponding slide-and-guide grooves 17, and spool 3 is provided with cam gear, and cam gear comprises cam tommy bar 8; Cam plate stem 8 is installed on the first adpting flange body 1, and cam plate stem 8 can rotate; The first adpting flange body, 1 lower end is provided with SEALING FITTING 6; Be provided with Packing spring 4 between the first adpting flange body 1 and the SEALING FITTING 6; Be provided with first return spring 5 between the first adpting flange body 1 and the valve shell 2, valve shell 2 inside are hinged with hangers 10 through connecting pin 9; Said secondary end device comprises the set casing 13 and the second adpting flange body 14; The set casing 13 and the second adpting flange body 14 interfix through fixing bolt 16; Secondary end device inside is provided with passive valve rod 11, and passive valve rod 11 and 14 of the second adpting flange bodies are provided with second return spring 15; Be respectively equipped with seal ring 7 on SEALING FITTING 6 and the passive valve rod 11.
The present invention adopts high-quality material, to guarantee the working life of its overlength.
The present invention is fixed on main end device and secondary end device on the in-and-out pipe mouth of fluid earlier in use.Under separated state, main end device and secondary end device are in sealing state separately under the effect of the cam gear and second return spring 15, make interior being closed with the interior fluid of reservoir area pipeline of tank car not reveal.When needs butt joint loading and unloading; Operator promote and rotary valve shell 2, and hangers 10 can be embraced the set casing 13 of secondary end device of the present invention, and the guide lugs on the first adpting flange body 1 12 breaks away from slide-and-guide groove 17 simultaneously; Make valve shell 2 be locked on the guide lugs 12 of the first adpting flange body 1; Pull cam tommy bar 8 then, promote spool 3, spool 3 promotes passive valve rod 11, and path is opened at two ends simultaneously like this; Fluid can pass through in the clear, reaches the purpose of loading and unloading flowing medium.
The present invention is in working order the time, and main end device and secondary end device are for be in open mode separately, and fluid can circulate smoothly.After having loaded and unloaded fluid, according to the above-mentioned steps reverse operating, can realize that promptly main end separates with secondary end, main end device and secondary end device recover air-tight state automatically.
