Abstract
The invention relates to a pneumatic control device in the industrial production process, in particular to a pneumatic two-position four-way slide valve capable of switching delivering or evacuating the working medium (liquid or gas) in the industrial production process. The pneumatic two-position four-way slide valve comprises a piston type actuating mechanism and a valve body assembly. The pneumatic two-position four-way slide valve has the advantages of high switching speed, long service life and difficult leakage, can enhance the control accuracy for switching delivering or evacuating the working medium, and is convenient for automatic control for the process control.
Description
Technical field
The present invention relates to the air control unit in the industrial processes, realize the switching of working medium (liquid or gas) is carried or switched the Pneumatic two-position four-way guiding valve of emptying in particularly a kind of industrial processes.
Background technique
Often need realize to switch carry or switch emptying in the modern industry production process working medium, and the fast and control accuracy that is related to slowly in the process control the working medium amount of its switch speed.Have only the sluggish problem that solves switch speed, could realize automation process control well, improve the control accuracy and to the adaptation of technological requirement to reach.There is following defective in prior art: the pneumatic actuator that 1. has homemade Pneumatic two-position four-way guiding valve now all adopts diaphragm actuator, because diaphragm is to be made by the rubber material, there are insufficient strength and easy problem of aging, therefore in use need frequent repair and replacement, this can influence industrial efficient and increase cost of production; 2. the valve rod that has homemade Pneumatic two-position four-way guiding valve now no longer carries out the hard chromium plating surface treatment after no longer finish grinding or finish grind after the Vehicle Processing, its roughness grade is not high, is easy to make the interior seal ring generation of valve body to cut phenomenon and causes leaking; The action sensitivity of 4. existing Pneumatic two-position four-way guiding valve is low, and switch speed is slow; During the two-way control of 5. existing Pneumatic two-position four-way guiding valve, need with two air bladder final controlling element, volume is big, and consumptive material is many, increase cost of production expense.Drawbacks such as in sum, existing homemade Pneumatic two-position four-way guiding valve exists switch speed slow, easily leaks, and working life is long, influence be to the control accuracy of working medium amount, the automatic control requirement in can not fine course of adaptation control system.
Summary of the invention
For solving problems of the prior art, the present invention aims to provide fast, the long service life of a kind of switch speed, antileakaging Pneumatic two-position four-way guiding valve can improve working medium is switched the control accuracy of carrying or switching emptying, is convenient to the automation control of process control.
Described Pneumatic two-position four-way guiding valve comprises piston actuator and valve body assembly; Wherein, described piston actuator comprises cylinder, piston, seal ring, pressing plate, fastening screw trip bolt, pressure spring and support, described seal ring is fixed on the piston by pressing plate, fastening screw trip bolt, cylinder is integral by being threaded with support, pressure spring is placed on piston and props up in the inner chamber that is configured to, reset when being used to a definite gas control signal value and unidirectional control are provided, respectively be provided with a gas control signal inlet opening on cylinder and the support; Described valve body assembly comprises the valve body 9 that is connected with support 8, cooperates in this valve body 9 to be provided with valve rod, seal ring and spool, and valve rod and piston link into an integrated entity, and seal ring is fixed on the spool; Valve body is provided with an inlet opening P, two delivery outlet A, B and an evacuation port O, the position by the control valve rod can make that P-A communicates, the B-O emptying, perhaps P-B communicate, the A-O emptying, perhaps P-B communicate, the A-O emptying.
Described Pneumatic two-position four-way guiding valve wherein, is provided with circular groove in the middle of the described seal ring, is provided with counterbalance spring in this circular groove.
Described Pneumatic two-position four-way guiding valve, wherein, the seal ring in the described valve body assembly is provided with five, and spool is provided with four.
Owing to have said structure, make the present invention have following effect:
One, because the present invention has long working life, and safe and reliable sealability can reduce maintenance rate, improves industrial production efficient, reduce production costs;
Two, because the present invention carries the switching of working medium or the switching intestine evacuation velocity is fast, can satisfy the technological requirement in the industrial processes preferably, improve the control accuracy.
