Abstract
The invention discloses a manual emergency mechanism for a quickly-closed type stop valve. The manual emergency mechanism is a manual translation mechanism arranged on a valve rod of the quickly-closed type stop valve. The quickly-closed type stop valve comprises a stop valve and a power cylinder; and the power cylinder comprises a piston, a piston rod and a cylinder cover connected with the stop valve. Two ends of the power cylinder are provided with unloading channels, the valve rod of the stop valve penetrates a valve cover upwards and is connected with a hand wheel, a compression spring is installed between the piston and the valve rod in a sleeved mode to form an elastic returning mechanism, and the valve rod extending out of the valve cover is provided with a radial pin shaft. A boss protruded upwards is arranged at the matched position of the valve cover and the valve rod and provided with an upward open groove, and the open groove is matched with the pin shaft to form an axial positioning mechanism and forms the manual translation mechanism together with the hand wheel. The manual emergency mechanism is simple in structure and convenient and rapid to operate, works reliably and is suitable for supporting of various stop valves.
Description
Technical field
The present invention relates to a kind of stop valve safety installations, specifically, the present invention relates to a kind of manual-operated emergent mechanism of quick closing valve stop valve.
Background technique
Quick closing valve stop valve is a kind of stop valve that heads straight for or directly close structure, because it has the features such as easy to operate, quick, is widely used in the pipe network of industrial and mining enterprise.Existing quick closing valve stop valve comprises stop valve, ram, is driven and is realized opening or closing of stop valve by ram.But existing quick closing valve stop valve is in the time running out of steam source, just cannot normally realize opening or closing of stop valve, at this moment, after generally ram and stop valve need being taken apart, manual mobile stop valve valve rod opens or closes stop valve, this process is not only bothersome, and consuming time longer, when the situation is critical, may cause greater loss.A kind of quick closing valve stop valve manual-operated emergent mechanism is disclosed in the patent " Quick-closing check valve self-provided emergency unloading mechanism " of China Patent Publication No. CN201582479U, this mechanism is arranged in the pressure cylinder being connected with stop valve, although this mechanism can carry out emergency processing in the time that abnormal conditions appear in stop valve, but because it is arranged in pressure cylinder, sealing to pressure cylinder is had higher requirement, make the complicated structure of pressure cylinder, and long-term use after wearing and tearing, because sealing place is leaked, meeting build-up of pressure cylinder pressure drop, affects pressure cylinder and normally works.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose one simple in structure, easy to operate, quick, the Quick-closing check valve manual-operated emergent mechanism of reliable operation.
The present invention is achieved through the following technical solutions technical goal.
Quick-closing check valve manual-operated emergent mechanism, it is provided in a side of the manual translation mechanism of Quick-closing check valve valve rod; Described Quick-closing check valve comprises stop valve, ram; Described ram comprises piston, piston rod and the cylinder cap being connected with stop valve; Described ram two ends are provided with unloading channel; Described stop valve valve rod upwards runs through valve gap, is connected with handwheel; Its improvements are: between described piston and cylinder cap, be set with Compress Spring, form flexible restoring organ; The valve rod that stretches out described valve gap is provided with radially bearing pin; Described valve gap and valve rod cooperation place are provided with boss protruding upward, and boss is provided with opening slot upwards, coordinate and form axial positioning mechanism, and form manual translation mechanism with bearing pin together with handwheel.
As the preferred version of such scheme, the height that when degree of depth of described opening slot is greater than stop valve emergency opening, valve rod need rise.
The present invention compared with prior art, has following good effect:
1. can realize manual-operated emergent operation, easy to operate, quick.
2. manual translation mechanism is arranged on valve gap, without changing ram structure, simple in structure, and sealing is reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
Quick-closing check valve manual-operated emergent shown in the drawings mechanism, it is provided in a side of the manual translation mechanism of Quick-closing check valve valve rod 2; Quick-closing check valve comprises stop valve 7, ram 9; Ram 9 comprises piston 9.2, piston rod 9.5 and the cylinder cap 9.4 being connected with stop valve 7; Ram 9 two ends are provided with unloading channel 9.1, between piston 9.2 and cylinder cap 9.4, are set with Compress Spring 9.3, form flexible restoring organ; Stop valve 7 valve rods 2 upwards run through valve gap 5, are connected with handwheel 1; The valve rod 2 that stretches out valve gap 5 is provided with radially bearing pin 3; Valve gap 5 is provided with boss protruding upward 4 with valve rod 2 cooperation places, and boss 4 is provided with opening slot 8 upwards, coordinates and forms axial positioning mechanism, and form manual translation mechanism with bearing pin 3 together with handwheel 1; In the present embodiment, when the degree of depth of opening slot 8 is greater than stop valve 7 emergency opening, valve rod 2 needs the height rising.
When something unexpected happened need to be adjusted the working state of stop valve 7 immediately, first open the unloading channel 9.1 at ram 9 two ends, piston rod 9.5 is under the effect of Compress Spring 9.3, be moved to the left, in piston rod 9.5 retraction cylinder caps 9.4, while needing to open stop valve 7 by hand, mention by hand handwheel 1, valve rod 2 is moved up together with bearing pin 3, in the time that bearing pin 3 arrives boss 4 upper-end surface, handwheel 1 is rotated to 40 °～90 °, unclamp handwheel 1, bearing pin 3, under the effect of valve rod 2 lower end Compress Springs 10, guarantees that bearing pin 3 and coordinating of boss 4 upper-end surfaces have coupling mechanism force; In the time needing Hand-sewn stop valve 7, hand-turning handwheel 1, makes bearing pin 3 again fall into opening slot 8, under the effect of valve rod 2 lower end Compress Springs 10, moves down, and realizes the closure of stop valve 7.
