Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of three-way control valve being convenient to keep in repair valve seat.
Background technique
Three-way control valve is by linear-motion electronic electric actuator and adopt three-way converging (shunting) valve of cylinder type thin-walled window-shaped spool to form.Have compact structure, lightweight, be active in one's movements, Flow characteristics is accurate, directly accept regulation meter input etc. control signal and single phase poaer supply can control running, realize the auto-adjustment control to process pipeline flowing medium, process parameter such as the parameters such as pressure, flow, temperature, liquid level being widely used in accurately controlling the media such as gas, liquid, steam remain on setting value.Existing three-way control valve is because of structural limitations, and dismounting maintenance is very inconvenient, and particularly valve seat part, can not carry out daily maintenance and replacing.
Model utility content
For prior art Problems existing, the purpose of this utility model is to design provides a kind of technological scheme being convenient to the three-way control valve keeping in repair valve seat.
Described a kind of three-way control valve being convenient to maintenance valve seat, comprise adapter, lower valve base, valve body, upper valve base, valve gap, valve hole part and actuator, described valve hole part comprises spool and valve rod, it is characterized in that described adapter and body base, valve gap and body top all adopt bolt to fix, described lower valve base is threaded with adapter, between described lower valve base and adapter, the first pad is set, described upper valve base is connected with valve body screw thread, arranges the second pad between described upper valve base and valve body.
Described a kind of three-way control valve being convenient to maintenance valve seat, is characterized in that described actuator is pneumatic diaphragn actuating mechanism.
Described a kind of three-way control valve being convenient to maintenance valve seat, is characterized in that the upper and lower two ends of described spool are cylinder guide sleeve structure.
Described a kind of three-way control valve being convenient to maintenance valve seat, is characterized in that the auxiliary section of described spool and lower valve base and spool and upper valve base is 30 ° of sealing surface structures.
Above-mentioned a kind of three-way control valve being convenient to maintenance valve seat, structure is simple, reasonable in design, adapter and body base, valve gap and body top all adopt bolt to fix, lower valve base is threaded with adapter employing, upper valve base adopts with valve body and is threaded, and conveniently to the dismounting of valve, conveniently can carry out daily maintenance and replacing to valve seat; Between lower valve base and adapter, the first pad is set, the second pad is set between upper valve base and valve body, forms complete sealing configuration, stop fluid and leak outside; Actuator adopts pneumatic diaphragn actuating mechanism, and structure is simple, reliable, easy to maintenance, after not producing igniting, improves Security in running; The upper and lower two ends of spool are cylinder guide sleeve structure, make to form leading role power between itself and upper lower valve base, improve the stability of valve; The auxiliary section of spool and lower valve base and spool and upper valve base is 30 ° of sealing surface structures, ensure that valve is not revealed.
