Description
Art
The present invention relates to a kind of sealing of novel glasses type push-pull valve, it is applied especially in pipeline.
Background technology
Enter China from the eighties.In less than the vicennial time, its use range extend to from general field
More wide all trades and professions.From the coal separation of mine power plant, discharge refuse, deslagging.The sewage disposal in city is developed into, from general
Industrial pipeline has developed into the special pipeline system such as food, health, medicine.Extra-thin knife gate valve is with its small volume, flow resistance is small,
The advantages that in light weight, easy to install, quick detachable, thoroughly solves common gate valve, flat gate valve, ball valve, stop valve, regulating valve, butterfly valve
The knotty problem that, weight big etc. the flow resistance of class valve is big, installation is difficult, floor space is big etc..It is substantial amounts of general after knife gate valve occurs
Cut-out class valve and control valve are substituted by it.To today, global knife gate valve dosage maximum is the U.S. and Japan.Push-pull valve
Also known as manual knife gate valve, it is a kind of valve that flashboard and valve seat are in close contact sealing all the time to knife-shape gate valve, and its principle is lock
The round mouth of a latus rectum size is provided with plate, opening and closing round mouth on flashboard by flashboard completely disengages and match with latus rectum
Action.The advantages of this valve, is valve body latus rectum un-grooved, medium will not jam block, it is and special with full-bore circulation
Property, its sealing structure can divide soft seal, hard sealing structure.Penetrating knife type gate valve is with precise construction, good manufacturability, structure
The features such as compact, seal valve seat are bascule, there is anti-wear and automatic compensation function, thus the life-span is longer.Closing closing and opening
Valve seat is close to move always with flashboard during opening so that valve opening and closing power is stable.
Spectacle push-pull valve is mounted to the board plug type gas partition valve of outdoor gas piping.It is high to be open in usual during work
During stove damping down, spectacle plate is closed, and cuts off gas piping.Because the valve mechanism is simple, in light weight, good sealing effect,
It is used widely on the gas piping of metallurgical system.
The content of the invention
During in order to overcome existing spectacle push-pull valve sealing in keying transition status, valve plate and valve body contact position
Displacement gaps can produce the problem of external leakage, and the present invention provides a kind of novel glasses type push-pull valve sealing, the type novel glasses type
Push-pull valve sealing has good sealing property, improves sealability during change working；On the basis for ensuring ability to work
On, improve its reliability used.
The technical solution adopted for the present invention to solve the technical problems is：Valve upper valve body is decomposed into valve body and flange sleeve,
Two part junctions selection gap coordinates；The sealing property of valve body and flange sleeve is realized by the effect of gland and airtight and watertight padding；
When needing opening/shutting valve, gland and filler are unclamped, valve body and flange inner room is carried out relative motion, reaches compensation valve
The effect of axial displacement.
Transition status external leakage phenomenon is opened and closed in order to solve spectacle push-pull valve, is matched somebody with somebody in the pressure-bearing direction of spectacle push-pull valve
Put the double eccentric butterfly valve of an identical latus rectum；Spectacle push-pull valve processes a close encapsulation groove on upper and lower valve body sealing surface respectively,
Airtight and watertight padding is filled in the seal groove of upper lower valve body, after valve installation, by rotating drive shaft, utilizes power transmission shaft both sides
Left-right rotary screw thread and the square nut outside drive sleeve, make airtight and watertight padding be in close contact with valve plate, reach the purpose of valve seal.
The beneficial effects of the invention are as follows：The convertibility of airtight and watertight padding is improved, from the cheap rubber asbestos disk of cost
Root reaches good sealing effectiveness as airtight and watertight padding；Compensator can reduce the production of valve while valve performance is ensured
Cost；External leakage caused by solving the problems, such as valve opening and closing State Transferring, realize do not dismantle and disintegration valve in the case of
Replacing to airtight and watertight padding, reduce the loss to user because of maintenance of valve, extend the service life of airtight and watertight padding, reduce
The cost of valve.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is to improve valve mechanism.
In Fig. 1,1. double eccentric butterfly valve, 2. metal o-ring, 3. fan-shaped push-pull valve.
Embodiment
Preferably, spectacle push-pull valve can all ensure the integral sealing effect of valve in sealing state or opening-wide state, reach
To zero leakage standard.
Preferably, spectacle push-pull valve processes a close encapsulation groove on upper and lower valve body sealing surface respectively, by airtight and watertight padding
It is filled in the seal groove of lower valve body, after valve installation, by rotating drive shaft, utilizes the left-right rotary screw thread of power transmission shaft both sides
With the square nut outside drive sleeve, airtight and watertight padding is in close contact with valve plate, reach the purpose of valve seal.
Preferably, transition status external leakage phenomenon is opened and closed in order to solve spectacle push-pull valve, in holding for spectacle push-pull valve
Direction is pressed to configure the double eccentric butterfly valve of an identical latus rectum, as shown in Figure 1.
Preferably, when spectacle push-pull valve changes its sealing state, double eccentric butterfly valve 1 is first shut off, then regulation is inserted
Plate valve valve plate；After spectacle push-pull valve State Transferring, double eccentric butterfly valve 1 is opened, completes conversion program；Although double eccentric butterfly valve 1
Micro-leakage can be produced under long-term air-tight state, but after it cuts off gas piping in advance, can prevent spectacle push-pull valve from opening
The external leakage phenomenon of closed state transfer process, reach the purpose of safety in production.
Preferably, airtight and watertight padding technique is changed in order to simplify spectacle push-pull valve, changes the sealing structure of valve, will be upper
The enclosure seal groove of lower valve body is changed to Open architecture, and outer face is three blocks of circular arc coaming plates, and every block of coaming plate is with fastening bolt
It is connected with seal groove.
Preferably, when airtight and watertight padding is failed, coaming plate need to only be dismantled, you can easily and quickly change airtight and watertight padding.
Preferably, in order to extend the service life of airtight and watertight padding, an adjustment is configured between airtight and watertight padding and seal groove top
Circle, after airtight and watertight padding wear, the space of airtight and watertight padding can be reduced by regulating bolt, increase airtight and watertight padding and valve plate
Tight ness rating, reaches the sealing effectiveness of valve, accordingly extends the service life of airtight and watertight padding.
When preferably, in order to open valve, the axial displacement redeeming to valve, former spectacle push-pull valve upper valve body
It is as compensation there is provided bellows.
Preferably, valve upper valve body is decomposed into valve body and flange sleeve, and two part junctions selection gap coordinates；Pass through gland
And the sealing property of valve body and flange sleeve is realized in the effect of airtight and watertight padding；When needing opening/shutting valve, gland and filler are unclamped,
Valve body and flange inner room is carried out relative motion, have the function that to compensate valve shaft to displacement；Compensator can ensure valve
While performance, the production cost of valve is reduced.
Preferably, adjusting ring is provided with the valve seat of safety valve, can preferably adjust blow pressure.
