Description
Technical field
The invention belongs to valve, has the gate valve that keying situation indicates function more specifically to a kind of.
Background technology
Existing gate valve indicates function without tool keying situation, and gate valve is often required that in actual production has this work(
Can, when such as the upstream of logistics system surprisingly stops conveying, downstream can't see liquid and flowed out, the gate valve in opening, easily
It is mistaken for being being closed, so that the pass is not related to, once, conveying is recovered in upstream, often wastes or occur security incident,
Further, in chemical industry production, when each flow with setting of multiple stream tubes conveys liquid material to same reactor, understand
The keying situation of gate valve is even more necessary in each stream tube.
Therefore it provides a kind of have the gate valve that keying situation indicates function, tool is of great significance.
The content of the invention
The present invention is a kind of to have the gate valve that keying situation indicates function, including rotary handwheel, valve body, bonnet, flashboard, valve
Bar, filler clamp nut, latex ring, bellows, the valve rod center has upward and downward to perforate, and in the handwheel and the compression
The chute of laterally excessively described perforation is provided between nut, the perforation is inserted with elevating lever, and the elevating lever lower end connects the lock
Plate bottom, upper end connects a cross bar, and the lower end of the valve rod is provided with circular depression, the latex around the perforation
Ring upward and downward integration is alternatively formed the thin-walled and heavy wall of elevating lever described in several rings, and the latex ring makes the elevating lever tight
It is close pass through after, its upper end is closely plugged in the depression, and the bellows upper end connects the cross bar, and lower end connects the pressure
Tight nut, the perisporium of the bellows is provided with hole, and when the flashboard rises to highest order, the bellows is in full exhibition state, and
The hole shows round shape.
The method have the advantages that：
By means of the shape that the hole is presented, intuitively reflect the keying situation of the gate valve.
Brief description of the drawings
Fig. 1 is that the present invention is a kind of has the unlatching state structural representation that keying situation indicates the gate valve of function.
Fig. 2 is that the present invention is a kind of has the closing state structural representation that keying situation indicates the gate valve of function.
Fig. 3 is the combination effect diagram between heretofore described latex ring and the elevating lever, the valve rod.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Shown in Fig. 1 or Fig. 2, Fig. 3, a kind of gate valve for having keying situation instruction function, including rotary handwheel 1, valve body 2,
There is upward and downward perforation 9 at bonnet 3, flashboard 4, valve rod 5, filler clamp nut 6, latex ring 7, bellows 8, the center of the valve rod 5, and
The chute 10 of laterally excessively described perforation 9 is provided between the handwheel 1 and the clamp nut 6, the perforation 9 is inserted with elevating lever
11, the lower end of the elevating lever 11 connects the bottom of flashboard 4, and upper end connects a cross bar 12, and the lower end of the valve rod 5 is described
Circular depression 13 is provided with around perforation 9, the upward and downward integration of the latex ring 7 has been alternatively formed elevating lever described in several rings
11 thin-walled and heavy wall, after the latex ring 7 allows the elevating lever 11 closely to pass through, its upper end is closely plugged on the depression 13
Interior, the upper end of the bellows 8 connects the cross bar 12, and lower end connects the clamp nut 6, and the perisporium of the bellows 8 is set
There is hole 14, when the flashboard 4 rises to highest order, the bellows 8 is in full exhibition state, and the hole 14 shows round shape.
It is in full reduced state at the bellows 8 when the flashboard 4 is minimized, the hole 14 shows flat slot, when described
4 liters of flashboard is down to when between highest order and lowest order, then the exhibition of the part of the bellows 8 or contracting, and the hole 14 shows ellipticity.Borrow
The shape that the hole 14 is presented, intuitively reflects the open/close states of the gate valve.
Each walled thickness in the latex ring is that distance is 1.2-1.8 millimeters between 0.3-0.8 millimeters, two heavy walls.
The latex ring 7 has several thin-walleds, then liquid material pressure of the bottom of latex ring 7 in the valve body 2 is made
Under, the elevating lever 11 can be all the time adjacent to, prevent liquid material from being spilt upwards between the valve rod 5 and the elevating lever 11.
The latex ring 7 is then difficult to ensure tight between the latex ring 7 and the elevating lever 11, influences such as without thin-walled
Sealing effectiveness, the thin-walled is single in this way, then can contract wrinkle when the elevating lever 11 is in lifting, influence the latex ring 7 to use
Life-span, the thin-walled is several in this way, then because being stopped by the upper and lower each heavy wall of thin-walled when the elevating lever 11 is lifted, contracting is wrinkled very
It is limited.
