Description
Technical field
It the utility model is related to gate valve equipment technical field, specially a kind of duplex gate valve with filter.
Background technology
Gate valve is an opening and closing element flashboard, and the direction of motion and flow direction of flashboard are perpendicular, gate valve can only make standard-sized sheet and
It is fully closed, uncomfortable door parameter and it is different, usually 5 °, when medium temperature is not high be 2 ° 52.Improve its manufacturability, make up sealing surface angle
Caused deviation in process, this flashboard are called flexible disc.When gate valve is closed, sealing surface can rely only on medium pressure
Power seals, that is, relies only on pressure medium and the sealing surface of flashboard is pressed into the valve seat of opposite side to ensure the sealing of sealing surface, this
It is exactly self sealss.Flashboard when that is, valve is closed, will be pressed to valve by most of gate valve by force using forced seal by external force
Seat, to ensure the sealing of sealing surface.The flashboard of gate valve is for linear motion with valve rod, is also Outside screw stem rising through handwheel type gate valve.Generally exist
There is trapezoidal thread on elevating lever, by the guide groove on the nut and valve body of valve tip, rotary motion be changed into moving along a straight line,
Namely operation torque is changed into operating thrust.During Open valve, when flashboard hoisting depth is equal to 1: 1 times of valve latus rectum,
The passage of fluid is completely unimpeded, but operationally, this position can not monitor.It is the summit work with valve rod during actual use
For mark, that is, motionless position is opened, as its fully open position.To consider that deadlock phenomenon occurs in temperature change, generally reaching
On vertex position, then refund 1/2-1 circles, the position as standard-sized sheet valve.
At present, existing gate valve using when be only used for being switched off and on the liquid flowed through, and liquid can not be carried out
Filter, tend to cause to block gate valve, due to gate valve small volume, being also inconvenient to dismantle and repair once be blocked, using
It is inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of duplex gate valve with filter, to solve to carry in above-mentioned background technology
The problem of going out, possessed beneficial effect are：The equipment is provided with filter in the porch of gate valve body, by filter
The screen pack in portion filters to the liquid for entering gate valve in advance, so as to avoid the impurity in liquid from blocking gate valve.
To achieve the above object, the utility model provides following technical scheme：A kind of duplex gate valve with filter, including
Filter housings, the side of the filter housings are provided with filter inlet, and the filter outlet that opposite side is set is located at valve
The side of body, and filter outlet is connected with valve body, the inside of the filter housings is fixed with strainer screen, and filter
Blind flange is installed, the fluid passage that the valve inner is set connects with filter outlet at the top of the flange of case top connection
Connect, and bonnet is connected with the top of valve body, the valve rod of the bottom installation of fixed handwheel passes through bonnet and valve at the top of the bonnet
The inside of body, the valve plate that the stem bottom is fixed are located at the inside of fluid passage.
Preferably, it is provided with handle at the top of the blind flange.
Preferably, the blind flange is connected with flange by fastener.
Preferably, the handwheel is connected with valve rod by axis of rotation.
Preferably, the bottom of the filter housings is provided with sewage draining exit.
Preferably, it is provided with helicla flute on the valve rod.
Preferably, the valve rod is threadably secured with valve plate is connected.
Compared with prior art, the beneficial effects of the utility model are：The equipment is provided with the porch of gate valve body
Filter, the liquid for entering gate valve is filtered in advance by the screen pack of filter interior, it is miscellaneous in liquid so as to avoid
Matter blocks gate valve, in addition, being provided with flange and blind flange at the top of filter, is easy to open blind flange periodically by filter
Screen pack, which is taken out, to be cleaned, and the screen pack after cleaning can be recycled, cost-effective.
