Description
Technical field：
The utility model belongs to valve technology field, more particularly, to a kind of shutoff type valve.
Background technology：
Valve is for being opened and closed pipeline, control flow direction, the parameter (temperature, pressure and flow) for adjusting and controlling pumped (conveying) medium
Pipeline fittings.According to its function, shut-off valve, check-valves, regulating valve etc. can be divided into.Valve is the control in fluid delivery system
Component has the function of cut-off, adjusting, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting or overflow pressure relief etc..For fluid control systems
Valve, various valves, kind and specification used in from simplest shut-off valve to extremely complex robot control system(RCS) are quite numerous
It is more.In practical applications in order to realize the big minor adjustment of liquid different flow, need the valve plate of valve that different open and-shut modes is presented,
Current shut-off valve and butterfly valve cannot achieve accurately controlling for uninterrupted.
Invention content：
Technical problem to be solved in the utility model is：There is provided it is a kind of different open and-shut modes is presented, to realize liquid
Body shuts off the valve of control.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：A kind of shutoff type valve, packet
Valve body, flow distribution plate, valve plate, protruding block, spring, adjusting bolt, screw rod and handwheel are included, the cross section of the valve body is
Rectangular configuration, the protruding block are shaped on the outer wall of valve body, are run through between the protruding block and valve body and are opened
Equipped with accommodating cavity, the valve plate lower end is sealingly mounted at by sealing ring in accommodating cavity, and the adjusting bolt passes through helicitic texture
Mounted on accommodating cavity outer end, the spring is placed in accommodating cavity, and the both ends of the spring is respectively acting on valve plate and adjusts spiral shell
On bolt, the flow distribution plate integrated molding is set on the inner wall of valve body, and the flow distribution plate is symmetricly set on valve plate
Both sides, the screw rod are sealingly mounted at by helicitic texture on valve body, and the upper end of the screw rod is connected with handwheel, described
The lower end of screw rod is in contact with valve plate.
Preferably, the screw rod lower end is provided with bearing turntable.
Preferably, the flow distribution plate is provided with two layers in valve body interior decile.
Preferably, the flow distribution plate is provided with sealing joint strip close to one end of valve plate.
Preferably, valve plate top both sides are set as rounded structure.
Compared with prior art, the usefulness of the utility model is：The utility model drives screw rod by rotating handwheel
Rotation, which is realized, squeezes valve plate, and then overcomes spring force, and valve plate moves down at this time, and liquid communication gap becomes larger at this time, leads to
Receiving and distributing wheel drives screw rod to be rotated up, and valve plate moves upwards under the action of the spring, and liquid communication gap becomes smaller at this time, carries out real
Now to the accurate control of shutting off of fluid flow.
