Abstract
The invention relates to a novel gate valve which comprises an executing mechanism (8), a valve plate stoke cavity (3) and a medium runner cavity (6), wherein the executing mechanism (8) is connected with a valve plate (5) extending into the valve plate stoke cavity (3) and the medium runner cavity (6) through a valve rod (1). The novel gate valve is characterized by further comprising a support (10), wherein two opposite ends on the support (10) are respectively fixedly connected with the executing mechanism (8) and the valve plate stoke cavity (3). Proved by try, after adopting the novel gate valve, defects that media are apt to accumulate in the gate valve stoke cavity, the valve plate is apt to be blocked and a travel switch is apt to have signal failure and inconvenient to maintain and replace are overcome, out leakage and pollution to the environment are reduced, leakage level is improved, inner leakage is reduced, use ratio of medium resources is improved, energy consumption is reduced, and energy conservation and emission reduction are achieved.
Description
Technical field
The present invention relates to a kind of novel push-pull valve.
Background technique
The structure of existing pneumatic push-pull valve is partly formed a valve body body by medium runner cavity and valve plate stroke cavity, and valve plate moves between medium runner cavity and valve plate stroke cavity, and cooperates with the simple valve seat of medium runner cavity, realizes the cut-out to medium.
But do not have sealing configuration between medium runner cavity and valve plate stroke cavity, cause valve plate after operation a period of time, medium is piled up in the stroke chamber, and the valve plate actuating length is stopped up, and can't realize the normal open and close of valve; The position limit switch of control valve plate action contacts with medium because of being built in the stroke cavity for a long time, can cause switching signal malfunctioning, need dismantle valve gap when maintenance, replacing, and medium is prone to the befouling environment that leaks outside; Valve plate does not have the valve seat of fitted seal, and interior leakage is big, and the medium utilization ratio is low, and energy consumption is big; Actuator directly is connected with valve body, and medium is prone to get in the actuator, actuator is used impact reduction of service life.
Summary of the invention
The purpose of this invention is to provide a kind of novel push-pull valve, can eliminate the influence of medium actuator.
A kind of novel push-pull valve; Comprise actuator, valve plate stroke cavity and medium runner cavity; Actuator through valve rod with stretch into valve plate stroke cavity and be connected with valve plate in the medium runner cavity; Its specialization is: also comprise a support, two ends relative on this support are fixedly connected with valve plate stroke cavity with actuator respectively.
Wherein the valve plate periphery in valve plate stroke cavity is equipped with packing seal mechanism.
Wherein the side near actuator has purge hole on valve plate stroke cavity wall.
The induction type position limit switch wherein is installed on the thread of actuator.
Wherein the side near actuator is communicated with medium runner cavity outlet place through guide channel on the valve plate stroke cavity.
Through probationary certificate, behind employing the present invention, efficiently solve easy accumulation medium in the push-pull valve stroke chamber, the easy jam of valve plate; And the position limit switch signal is easy to failure, keep in repair and change inconvenient defective; Reduced leaking outside, reduce pollution, improved leakage class, reduced interior leakage, improved the utilization ratio of media resource environment; Reduce energy consumption, realized energy-saving and emission-reduction.Install indirectly with valve body through actuator and to be connected, having eliminated medium influences actuator, has improved the working life of actuator.
Description of drawings
Accompanying drawing 2 is a structural representation of the present invention.
Embodiment
As shown in Figure 1; The present invention is a kind of novel push-pull valve; Comprise actuator 8, valve plate stroke cavity 3 and medium runner cavity 6; Actuator 8 through valve rod 1 with stretch the valve plates 5 that (inserting) go in valve plate stroke cavity 3 and the medium runner cavity 6 and be connected, also comprise a support 10, two ends relative on this support 10 are fixedly connected with valve plate stroke cavity 3 with actuator 8 respectively.
Side near actuator 8 on valve plate stroke cavity 3 sidewalls has purge hole 2; The compressed nitrogen of this Kong Keyu field control system is connected; Through controlling the compressed nitrogen of in purge hole, importing; Can the medium that leak in the valve plate stroke cavity 3 finally be blown into downstream line with compressed nitrogen, proceed the utilization of resources.
As shown in Figure 2; On the thread 9 of actuator 8 outsides, induction type position limit switch 11 is installed; The present invention installs induction type position limit switch 11 on thread 9, can realize the adjustment control to valve stroke through the mounting point of adjustment induction type position limit switch 11; When induction type position limit switch 11 breaks down, owing to adopted outside mounting type, be convenient to dismounting and maintenance, and do not influence the normal use of valve.
Side near actuator 8 on the valve plate stroke cavity 3 is communicated with medium runner cavity 6 outlet ports through guide channel 7; The design of this guide channel 7; Be for the ease of will and purging the outlet port that the leaking medium effective and rapid of carrying be directed to the medium runner cavity, and pipeline is carried downstream from the compressed nitrogen of purge hole input.
Claims (5)
