Abstract
The utility model discloses a gate board type blanking valve, comprising an upper body of valve, a lower body of valve, a mounting plate, a hydraulic cylinder, a piston rod and a gate board. The upper and lower body of valves are fixedly connected and the middle forms recess where the gate board is arranged; the upper body of valve is fixed to one end of the mounting plate and the other end of the mounting plate is fixedly connected with the hydraulic cylinder; a cylinder rod is connected with the gate board and one end of the gate board has a sealing element. The utility model has the advantages of compact conformation, convenient demounting and maintenance, good use effect, etc, which is suitable to various bad situations.
Description
Technical field:
The utility model relates to a kind of control valve.
Technical background:
The flashboard type laying-off valve is that a kind of fluid of controlling ends/through-flow control valve member, belongs to the position control valve class.Gate valve since simple in structure flexibly, by/through-flow reliable in action, can be under abominable working environment proper functioning, be fit to big flow fluid, advantage such as with low cost at home and abroad is widely used with the various FLUID TRANSPORTATION controls of industries such as factory, mine in, especially be fit to the conveying Control work of materials such as powder, particle.The shortcoming of gate valve is obvious equally with advantage, mainly contain: the valve body structure size is big, weight is difficult for the stuck easily or damage of installation and removal, flashboard greatly, cause operational failure, main motive sealing to damage easily, cause leakage, damage back to need usually to change whole valve body, workload is big.Therefore, gate valve is not suitable for controlling the occasion that requirement is very high, the space is narrow and small, peripheral equipment is high to environmental requirement.
Summary of the invention:
The purpose of this utility model is: provide a kind of compact structure, dismounting, easy to maintenance, flashboard type laying-off valve that using effect is good, to overcome the problems referred to above.
The utility model is to constitute like this: it is by upper valve body (1), following valve body (2), mounting plate (3), oil cylinder (4), piston rod (5), flashboard (6) is formed, upper and lower valve body (1), (2) are fixedly connected, the middle groove (7) that forms, and flashboard (6) is loaded in the groove (7); Upper valve body (1) is fixed on an end of mounting plate (3), the fixedly connected oil cylinder of the other end (4) of mounting plate (3), and piston rod (5) is connected with flashboard (6); One end of flashboard (6) has Sealing (8).
Place suitable for reading at following valve body (2) has channelization angle (9), and is provided with support bar (10).
The utility model compared with prior art has the following advantages:
1, outside mounting flange is an one with valve body up and down, compact structure, and seal point is few.
2, valve body is provided with channelization angle down, is beneficial to material.Channelization angle is custom-designed for the material proper flow that guarantees the gate valve conveying.When gate valve was opened, the impact and the directing material of the free fall of channelization angle buffering material flowed, and after gate valve cut out, channelization angle continued flow material emptying in valve body down of directing material, to prevent to stop up and flashboard is stuck and damage.
3, the support of flashboard guiding is reliable, the groove guiding of flashboard by offering on the upper valve body, and guiding length is big, and flashboard can reliablely and stablely move, and also is being provided with support bar on the valve body down, makes flashboard be difficult for stuck or damage.
4, sealing configuration is convenient and reliable, leaks little; Main motive sealing damages the back and changes conveniently.Because up and down the valve body surface of contact is smooth and area of contact is big, can effectively guarantee sealing.The sealing of two-layer industrial felt is used in the motive sealing at flashboard place, utilizes felt quality softness, character that containment is good to reach sealing effect and with low cost.This two place is sealed into Changable type in addition, only need regularly change the integral sealing effect that just can guarantee gate valve.
5, the whole valve body once mounting puts in place, need not dismantle valve body after flashboard and the bad seals, safeguards simple and convenient.After the gate valve installation, valve body just need not be dismantled up and down, breaks down, and is stuck or infringement of flashboard and motive sealing wearing and tearing usually, at this moment pulls out flashboard and repairs and change sealing and get final product, and is very convenient.
Description of drawings:
Accompanying drawing 1 is a structure principle chart of the present utility model;
Accompanying drawing 2 is that the A of accompanying drawing 1 is to view.
Embodiment:
Embodiment of the present utility model: the flange of upper and lower valve body (1), (2) connects with bolt, the middle groove (7) that forms, and flashboard (6) is loaded in the groove (7); Upper valve body (1) is fixed by bolts to an end of mounting plate (3), and the other end of mounting plate (3) connects oil cylinder (4) with bolt, and the piston rod (5) in the oil cylinder (4) is connected with bearing pin with flashboard (6); One end of flashboard (6) is equipped with two-layer industrial felt Sealing (8).
Place suitable for reading at following valve body (2) has channelization angle (9), and is provided with support bar (10).
Claims (2)
1, a kind of flashboard type laying-off valve, it is by upper valve body (1), following valve body (2), mounting plate (3), oil cylinder (4), piston rod (5), flashboard (6) is formed, it is characterized in that: upper and lower valve body (1), (2) are fixedly connected, the middle groove (7) that forms, and flashboard (6) is loaded in the groove (7); Upper valve body (1) is fixed on an end of mounting plate (3), the fixedly connected oil cylinder of the other end (4) of mounting plate (3), and piston rod (5) is connected with flashboard (6); One end of flashboard (6) has Sealing (8).
