Description
Technical field
The invention belongs to valve, more specifically to a kind of gate valve for having open/close states indicator function.
Background technology
Gate valve is used for liquid stream system in chemical industry, and a kind of its keying of existing gate valve is to borrow rotary handwheel
Realize counterclockwise or rotationally clockwise, although rotary handwheel indicates the force direction instruction on keying,
It is without the indicator function on open/close states, and to often require that gate valve has this function in actual production, such as logistics system
When the upstream of system surprisingly stops conveying, liquid outflow has been can't see in downstream, the gate valve in opening, easily is mistaken for being being in
Closed mode, so that the pass is not related to, once, conveying is recovered in upstream, often wastes material or security incident occurs.
Therefore it provides a kind of gate valve for having open/close states indicator function, tool are of great significance.
The content of the invention
It is an object of the invention to provide a kind of gate valve for having open/close states indicator function.
A kind of gate valve for having open/close states indicator function of the present invention, including rotary handwheel, valve body, the valve of upper even swivel nut
Lid, flashboard, valve rod, filler clamp nut, formed with screw thread on the valve rod between the handwheel and the nut, outside the screw thread
It is bolted with the female lifting wheel of its centre bore, it is female that the swivel nut in the nut bottom is bolted with its centre bore
Indicator fixed cover, the fixed cover side are provided with the label of the picture and text of indicative significance containing open/close states towards the handwheel,
The label upward and downward is provided with chute, and the lifting wheel, which radially extends, is provided with indicator, and the indicator stretches into described
Lifted in chute, and it is consistent with the lifting direction of the flashboard to lift direction.
The present invention can also be：
Pulley is cased with outside the indicator.
The method have the advantages that：
By means of position of the indicator on the label, the open/close states of gate valve are visually known.
Brief description of the drawings
Fig. 1 is a kind of structural representation for the gate valve for having open/close states indicator function of the present invention.
Fig. 2 is Fig. 1 side structure schematic view.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Shown in Fig. 1 or Fig. 2, a kind of gate valve for having open/close states indicator function, including rotary handwheel 1, valve body 2, upper company
The bonnet 3 of swivel nut, flashboard 4, valve rod 5, filler clamp nut 6, formed on the valve rod 5 between the handwheel 1 and the nut 6
There is screw thread, be bolted with the female lifting wheel 7 of its centre bore outside the screw thread, the swivel nut is bolted with the bottom of nut 6
The female indicator fixed cover 8 of its centre bore, the side of fixed cover 8 are provided with towards the handwheel 1 shape containing keying
The label 9 of state indicative significance picture and text, the upward and downward of label 9 are provided with chute 10, and the lifting wheel 7, which radially extends, to be provided with
Indicator 11, the indicator 11 are stretched into the chute 10 and lifted, and lift direction and the lifting direction phase one of the flashboard 4
Cause.
To send noise and abrasion, the overcoat of indicator 11 when preventing the indicator 11 from being lifted in the chute 10
There is pulley, make to be rolling friction between the indicator 11 and the chute 10.The pulley is preferably in round table-like, and is nearly institute
State the end diameter of handwheel 1 and be more than the other end, do not fall off during ensuring the pulley rolling.
The label 9 is in the picture and text with the 10 high-end corresponding position of chute mark meaning containing unlatching；With the chute 10
Low side corresponding position mark is containing the picture and text for closing meaning.By means of position of the indicator 11 on the label 9, lock is visually known
The open/close states of valve.
Handwheel 1 as described in counterclockwise rotates, the accompanying rotation of valve rod 5, then the flashboard 4 rise, meanwhile, it is described
Lifting wheel 7 rises, and the pin 11 in the chute 10 also rises, until containing up to the 10 high-end corresponding position of chute mark
At the picture and text for opening meaning.
