Description
Technical field
The invention belongs to valve, the gate valve of function is blocked more specifically to a kind of instruction of tool open/close states and leakage.
Background technology
Gate valve is used for liquid stream system in chemical industry, and a kind of existing gate valve its keying is to borrow rotary handwheel
Counterclockwise or rotationally clockwise realize, rotary hand is bright, although indicate the force direction on opening and closing and indicate, but
It is that without the instruction function on open/close states, and gate valve is often required that in actual production has this function, such as logistics system
When the upstream of system surprisingly stops conveying, downstream can't see liquid and flowed out, 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 or occur security incident.
Further, when the filler in filler clamping nut or Packing seat are damaged, liquid material is often compressed from valve rod and filler
Rotary handwheel is sprayed onto between nut, so that operating personnel are difficult to free-hand close to rotary handwheel, closing gate valve,
Therefore it provides a kind of tool open/close states are indicated and the gate valve of function is blocked in leakage, tool is of great significance.
The content of the invention
It is an object of the invention to provide the gate valve that function is blocked in a kind of instruction of tool open/close states and leakage.
The gate valve of function, including rotary handwheel, valve body, valve are blocked in a kind of tool open/close states instruction of the present invention and leakage
Lid, flashboard, valve rod, filler clamping nut, bellows, slide bar, the valve rod is formed between the handwheel and the clamping nut
There is screw thread, the screw thread is bolted with lifting wheel, and there is screw at the lifting wheel center, and upward and downward is set between the screw and edge
One slide opening, the clamping nut is provided with jack, and the slide bar passes through the slide opening parallel to the valve rod, and plugs together in institute
Jack is stated, when the perisporium of the bellows is provided with indicator hole, and the bellows in full exhibition state, the indicator hole manifests circle
Shape, the bellows upper end is fixedly connected with the lifting wheel edge, and the bellows lower end is connected with and falls again, and the heavy pendant is received
The clamping nut holding, the lifting wheel is consistent with flashboard lifting direction.
The method have the advantages that：
By means of the shape that the indicator hole of the bellows perisporium is presented, intuitively and visually reflect the keying shape of the gate valve
State；
By means of the lifting wheel and the bellows, by from rushing at the handwheel between the valve rod and the clamping nut
Leakage fluid is blocked.
Brief description of the drawings
Fig. 1 is gate valve of the present invention in structural representation when state is opened entirely.
Fig. 2 is structural representation of the gate valve of the present invention when close to full-shut position.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Shown in Fig. 1 or Fig. 2, a kind of have that open/close states are indicated and the gate valve of function, including rotary handwheel 1 are blocked in leakage,
Valve body 2, bonnet 3, flashboard 4, valve rod 5, filler clamping nut 6, bellows 7, slide bar 8, the valve rod 5 is in the handwheel 1 and institute
Screw thread is formed between stating clamping nut 6, the screw thread is bolted with lifting wheel 9, there is screw at the center of the lifting wheel 9, and in the spiral shell
Upward and downward sets a slide opening between hole and edge, and the clamping nut 6 is provided with jack, and the slide bar 8 is parallel to the valve rod 5
Through the slide opening, and plug together in the jack, the perisporium of the bellows 7 is provided with hole and indicates 10, and the bellows 7 is in
During full exhibition state, the indicator hole 10 manifests circle, and the upper end of the bellows 7 is fixedly connected with the edge of the lifting wheel 9, the ripple
The lower end of line pipe 7 is connected with and falls 11 again, and the heavy pendant 11 receives the holding of the clamping nut 6,4 liters of the lifting wheel 9 and the flashboard
Drop direction is consistent.
The bellows 7 is by plastics or rubber, latex type system.
Handwheel 1 as described in counterclockwise rotates, the accompanying rotation of the valve rod 5, then the flashboard 4 rise, meanwhile, it is described
Lifting wheel 9 rises under the threaded function along the slide bar 8, drives the bellows 7 to stretch, when the flashboard 4 is promoted to
During highest order, state is opened up at the bellows 7 entirely, the indicator hole 10 manifests circle, as shown in figure 1, when the flashboard 4 is down to most
During low level, full reduced state at the bellows 7, the indicator hole 10 shows flat slit, as shown in Fig. 2 when 4 liters of the flashboard is down to most
When between high-order and lowest order, then the indicator hole 10 manifests ellipse.
When the filler in the clamping nut 6 or Packing seat are damaged, liquid material can be from the valve rod 5 and the compression spiral shell
The lifting wheel 9 is sprayed onto between cap 6, in the bellows 7 after buffering, from heavy pendant 11 its described and the indicator hole 10 to
Lower leakage, the handwheel 1 is rushed at from leakage fluid is avoided.
