Abstract
The utility model relates to a kind of ethyl p-toluenesulfonate still bottom valve handle sleeve, and described connecting tube is a telescopic pipe, and this telescopic pipe comprises at least one joint telescopic section, and described telescopic section is formed by installing locking mechanism between the inner and outer tubes be oppositely arranged; The top of telescopic pipe is threaded fixing with fitting seat.The utility model has the advantage of: cover pipe connected pipe is first enclosed within still bottom valve handle by the utility model sleeve pipe, then people is upwards pushed away by hand-held pipe, hand-held pipe and cooperatively interacting of connecting tube rotate thus open still bottom valve, simultaneously due to can the existence of resilience positive stop strip, cause connecting tube only can forward several angle to just to stop operating, complete spacing; Only need reverse complete operation of exerting all one's strength as closed still bottom valve, connecting tube can change length according to highly different, thus reaches the effect increasing the arm of force.
Description
Technical field
The utility model relates to a kind of sleeve pipe, especially a kind of ethyl p-toluenesulfonate still bottom valve handle sleeve.
Background technique
In Chemical Manufacture, reactor is one of necessary equipment of chemical industry, and the valve bottom reactor is also one of equipment of reactor indispensability simultaneously.
In some specific reactors, the such as reactor of 10 tons, at the bottom of its still, distance ground is too high, causing cannot normal running, sleeve pipe conventional is at present directly just a straight tube, inoperative under some specific reactors, market there is a kind of handle sleeve, its connecting tube is fixed length, hand-held pipe is sleeve pipe, the length of its hand-held pipe is far longer than connecting tube, its arm of force is little, so require great effort very much, therefore just must develop one and can complete altitude switch still bottom valve and labour-saving device, through retrieval, do not find the same or analogous device with the utility model.
Model utility content
The technical problems to be solved in the utility model is to provide one can complete altitude switch still bottom valve and labour-saving device.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of ethyl p-toluenesulfonate still bottom valve handle sleeve, its innovative point is: comprise a hand-held pipe, and a connecting tube, hand-held pipe and connecting tube hinged, hand-held pipe and connecting tube one side end are provided with the spacing hole cooperatively interacting and rotate at unique vertical plane, two spacing hole joints are provided with one along the sense of rotation side of connecting tube can resilience positive stop strip, described connecting tube upper end be provided with a pore volume receive still bottom valve handle embed cavity, the internal diameter of connecting tube can hold still bottom valve handle and embed in pipe, described connecting tube is for being a telescopic pipe, this telescopic pipe comprises at least one joint telescopic section, described telescopic section is formed by installing locking mechanism between the inner and outer tubes be oppositely arranged, described locking mechanism comprises locking nut and locking ring, locking nut is made up of the outer sleeve coaxially arranged and inner sleeve, described outer sleeve can be connected with the outer tube nose threads of telescopic pipe by internal thread, inner sleeve just can embed in outer tube, locking ring is an annular nylon part being distributed with some deformation seam vertically, the outer tube front end of telescopic pipe has the reducer that reduces gradually of internal diameter from outside to inside, the external diameter of locking ring is less than reducer maximum inner diameter and is greater than reducer minimum diameter, the top of telescopic pipe is threaded fixing with fitting seat.
The utility model has the advantage of: cover pipe connected pipe is first enclosed within still bottom valve handle by the utility model sleeve pipe, then people is upwards pushed away by hand-held pipe, hand-held pipe and cooperatively interacting of connecting tube rotate thus open still bottom valve, simultaneously due to can the existence of resilience positive stop strip, cause connecting tube only can forward several angle to just to stop operating, complete spacing; Only need reverse complete operation of exerting all one's strength as closed still bottom valve, connecting tube can change length according to highly different, thus reaches the effect increasing the arm of force.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model ethyl p-toluenesulfonate still bottom valve handle sleeve.
Structural representation when Fig. 2 is the work of the utility model ethyl p-toluenesulfonate still bottom valve handle sleeve.
Embodiment
A kind of ethyl p-toluenesulfonate still bottom valve handle sleeve as shown in Figure 1, comprise a hand-held pipe 1, and a connecting tube 3, hand-held pipe 1 is hinged with connecting tube 3, hand-held pipe 1 is provided with connecting tube 3 one side end the spacing hole 2 cooperatively interacting and rotate at unique vertical plane, two spacing hole joints are provided with one along the sense of rotation side of connecting tube can resilience positive stop strip 4, described connecting tube 3 upper end be provided with a pore volume receive still bottom valve handle embed cavity, the internal diameter of connecting tube 3 can hold still bottom valve handle and embed in pipe, connecting tube 3 is for being a telescopic pipe, this telescopic pipe comprises at least one joint telescopic section, described telescopic section is formed by installing locking mechanism between the inner and outer tubes be oppositely arranged, described locking mechanism comprises locking nut and locking ring, locking nut is made up of the outer sleeve coaxially arranged and inner sleeve, described outer sleeve can be connected with the outer tube nose threads of telescopic pipe by internal thread, inner sleeve just can embed in outer tube, locking ring is an annular nylon part being distributed with some deformation seam vertically, the outer tube front end of telescopic pipe has the reducer that reduces gradually of internal diameter from outside to inside, the external diameter of locking ring is less than reducer maximum inner diameter and is greater than reducer minimum diameter, the top of telescopic pipe is threaded fixing with fitting seat.
Its working principle is: cover pipe connected pipe 3 is first enclosed within still bottom valve handle by the utility model sleeve pipe, then people is upwards pushed away by hand-held pipe 1, hand-held pipe 1 rotates with cooperatively interacting of connecting tube 3 thus opens still bottom valve, simultaneously due to can the existence of resilience positive stop strip, cause connecting tube 3 only can forward several angle to just to stop operating, complete spacing; Only need reverse complete operation of exerting all one's strength as closed still bottom valve, connecting tube 3 can change length according to highly different, thus reaches the effect increasing the arm of force.
