Abstract
The utility model discloses a return mechanism used in a semi-rotary valve. The semi-rotary valve comprises a valve body, an upper casing, a connecting rod, a valve rod, a valve core and a handle, wherein a flange is arranged on the valve body; the upper casing is fixed with the flange; the valve rod is connected with the valve core in the valve body penetrating through the flange; the connecting rod linked with the valve rod is arranged in the upper casing in a penetrating way; the handle is fixed on the connecting rod and fixed with the upper casing through a positioning pin shaft; a return torsion spring is arranged between the connecting rod and the upper casing; and the return torsion spring is sleeved on the connecting rod, one extension end of the returning torsion spring is fixed on the connecting rod, and the other extension end is fixed with the upper casing. Since the traditional spring return actuator is replaced by the return torsion spring, the complicated structure of the traditional return mechanism is simplified, so that the installation process of the return torsion spring is simple and convenient, and the manufacturing cost is lower; moreover, owing to simple and convenient manual return operation of the return torsion spring, the prior rotary angle of the handle can be arranged more flexibly, and any angle can be preset according to the requirements of a user.
Description
Technical field
The utility model relates to a kind of half turning valve, especially a kind of response agency of half turning valve.
Background technique
Half turning valve generally can be preset as required and open or close two states, handle Rotate 180 ° again, allow pretightening force be loaded on the handle, and accomplish fluently alignment pin handle and upper shell are fixed, after handle lost efficacy, response agency can discharge previous pretightening force, makes valve rod drive the predeterminated position that the spool Rotate 180 ° is returned to valve.At present, generally the response agency of Shi Yonging is a spring reset formula final controlling element, being provided with pressure spring within the outer shell is used for external bleed pressure is converted into elastic force, the motion of the restoring force lead agency of pressure spring makes valve keep default state after external source of the gas is cut off, therefore this spring reset formula final controlling element needs the outside that compressed air supplies is arranged, and comprise the three linked piece that connecting tube that compressed air supplies is carried and pressurized air are handled, control the parts such as solenoid valve of pressurized air turnover in addition, this spring reset formula actuator structure complexity, mounting process is loaded down with trivial details, and cost of production is higher.
Summary of the invention
At the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and mounting process is easy, and the response agency of lower half turning valve of cost of production.
For achieving the above object, the utility model provides a kind of response agency of half turning valve, half turning valve comprises valve body, upper shell, connecting rod, valve rod, spool, handle, and valve body is provided with and connects dish, and upper shell is with to connect dish fixing, valve rod passes and connects the interior spool of dish and valve body and be connected, connecting rod is located in the upper shell, and links with valve rod, and handle is fixed on the connecting rod, handle and upper shell are fixed by alignment pin simultaneously, are provided with the answer torsion spring between connecting rod and the upper shell.
The utility model can further be set to described answer torsion spring set and be located on the connecting rod, and an extending end is fixed on the connecting rod, and another extending end and upper shell are fixed.
The beneficial effects of the utility model are: owing to replaced traditional spring reset formula final controlling element with the answer torsion spring, the response agency of original complexity is simplified the structure, it is easy to reply the torsion spring mounting process simultaneously, and cost of production is lower; Simultaneously because the manual reset ease-to-operate of answer torsion spring is so the angle that handle rotates in advance has more flexibility, according to user's needs, predeterminable arbitrarily angled.

Embodiment
Provided a kind of response agency of half turning valve as shown in Figure 1, 2, 3, half turning valve comprises valve body 1, upper shell 2, connecting rod 3, valve rod 4, spool 5, handle 6, valve body 1 is provided with and connects dish 11, upper shell 2 with connect dish 11 and pass through bolt, valve rod 4 passes and connects the interior spool 5 of dish 11 and valve body 1 and be connected, connecting rod 3 is located in the upper shell 2, and with valve rod 4 interlock, described connecting rod 3 lower ends 31 end faces are provided with the cavity 311 that cooperates with valve rod 4, insert in the cavity 311 of connecting rod 3 upper end 41 of valve rod 4, forms card with connecting rod 3 and join interlock.Handle 6 is set on the upper end 32 of connecting rod 3, and is fixed in by packing ring 7 and nut 8 on the upper end 32 of connecting rod 3, is provided with between connecting rod 3 and the upper shell 2 to reply torsion spring 9.Upper shell 2 is provided with a through hole 21, offer keyway 312 on the lower end 31 of connecting rod 3, described answer torsion spring 9 is set on the connecting rod 3, and an extending end 91 colludes in the keyway 312 on connecting rod 3 and fix, and fixes in the through hole 21 that another extending end 92 inserts on upper shells 2.
Half turning valve can be preset as required and open or close two states, handle 6 rotates a predetermined angle again, driving connecting rod 3 in the time of handle 6 rotations rotates, transference connecting rod 3 fixing answer torsion springs 9 are loaded into pretightening force on the handle 6, and accomplish fluently alignment pin 61 handle 6 and upper shell 2 are fixed, after handle 6 lost efficacy, reply torsion spring 9 and can discharge previous pretightening force, driving connecting rod 3 resets, because connecting rod 3 and valve rod 4 interlocks, so valve rod 4 drives the predeterminated position that spool 5 rotations are returned to valve.
Owing to replaced traditional spring reset formula final controlling element with answer torsion spring 9, the response agency of original complexity is simplified the structure, it is easy to reply torsion spring 9 mounting processs simultaneously, and cost of production is lower; Simultaneously because the manual reset ease-to-operate of answer torsion spring 9 is so the angles that handle 6 rotates in advance have more flexibility, according to user's needs, predeterminable arbitrarily angled.
