Description
Technical field
The utility model relates to a kind of rapid escape valve, relates in particular to a kind of straight-through type rapid escape valve.
Background technique
Rapid escape valve is as industrial accessory commonly used, and a lot of operating modes have larger demand for pore actuator, especially are widely used in the fields such as electric power, petroleum and chemical industry.General cylinder is in order to realize the quick acting of piston, and the use rapid escape valve, all generally that the rapid escape valve that adopts is all that pipeline connects at present, need to arrange pipeline in cylinder and outlet valve, it relatively takes up room, not attractive in appearance, increasing to equipment of joint brings the problems such as poor in sealing simultaneously.
Summary of the invention
The purpose of this utility model is the defect that exists for prior art, a kind of integral installation is provided, need not the straight-through type rapid escape valve that pipeline connects, sealing is high.
for achieving the above object, the utility model adopts following technical proposals: the straight-through type rapid escape valve, comprise the spool that is arranged in square tube shape valve body, one side of described valve body is installed with valve gap, be provided with two piston nonreturn valve cores in described valve body, described valve body is provided with two symmetrically arranged directed cavity in up and down, be respectively falling in valve block upper half and be provided with directed cavity under " T " font in directed cavity and valve block lower half on " T " font, described directed cavity is provided with three interfaces in valve body surface and is respectively on cover plate in the suction port of the laterally straight-through chamber of directed cavity one end, air outlet on the laterally straight-through chamber the other end of directed cavity, the vertical chamber of directed cavity is in the working hole on valve body or on lower surface, vertical chamber of directed cavity is communicated in laterally straight-through chamber near the position, air outlet, be provided with the central shaft that axially sets up along laterally straight-through cavity in described laterally straight-through chamber, described piston nonreturn valve core is installed on central shaft, two piston nonreturn valve cores are controlled its moving along central shaft by gas push.
As a kind of improvement: the piston nonreturn valve core in described directed cavity comprises and coaxially is assemblied on central shaft the core body that can slide along central shaft, is fixedly connected on the one-way valve on core body and is fixed in the slide valve assembly of core body front end, along with driving slide valve assembly, core body moves along central shaft, slide valve assembly can stop up and open vertical chamber and laterally lead directly to the connectivity part in chamber, thereby closes and open the path between air outlet and working hole.
As a kind of improvement: on the front end of described slide valve assembly, with scrobicular ring, described scrobicular ring is embedded with seal ring.
As a kind of improvement: also comprise two bafflers, described two bafflers cover respectively on the working hole of two of up and down.
Adopt the rapid escape valve of such scheme, all by the electric drive element is unified, controlled by two set thereon spools, two spools can be accomplished staggered exhaust, do not have reciprocal influence between two spools,, for independence, there do not is stationary problem in stroke work.Installing, need not pipeline and connect, directly integral installation on cylinder, had both been saved cost, had avoided again interface to increase and produced the poor problem of sealing, maintained easily and adjusted.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Embodiment
as shown in Figure 1, a kind of specific embodiment of the utility model straight-through type rapid escape valve, comprise the spool that is arranged in square tube shape valve body 2, valve body 2 one sides that described integral body is directly installed on cylinder are installed with valve gap 1, be provided with two piston nonreturn valve cores in described valve body 2, described valve body 2 is provided with two symmetrically arranged directed cavity 7 in up and down, be respectively falling in valve body 2 first halves and be provided with directed cavity 7-2 under " T " font in directed cavity 7-1 and valve body 2 Lower Halves on " T " font, the directed cavity 7-1 that falls on " T " font in described valve body 2 first halves is provided with three interfaces and is respectively on cover plate 1 in the enterprising gas port 8-1 of the upper laterally straight-through chamber of upper directed cavity 7 end in valve body 2 surfaces, upper air outlet 9-1 on the upper laterally straight-through chamber the other end of upper directed cavity 7-1, the upper working hole 10-1 of upper vertical chamber of upper directed cavity 7-1 on valve body 2 upper surfaces, described lower directed cavity 7-2 is provided with three interfaces and is respectively on cover plate 1 in the lower suction port 8-2 of the lower laterally straight-through chamber of lower directed cavity 7-2 one end in valve body 2 surfaces, lower air outlet 9-2 on the lower laterally straight-through chamber the other end of lower directed cavity 7-2, the lower working hole 10-2 of lower vertical chamber of lower directed cavity 7-2 on valve body 2 lower surfaces.Upper vertical chamber of upper directed cavity 7-1 is communicated in laterally straight-through chamber near 9-1 position, upper air outlet, and lower vertical chamber of lower directed cavity 7-2 is communicated in lower laterally straight-through chamber near 9-1 position, lower air outlet.Two of up and down are equipped with the central shaft 13 that axially sets up along laterally straight-through cavity in laterally straight-through chamber, described two piston nonreturn valve cores are installed on respectively on central shaft 13, two piston nonreturn valve cores are by its moving along central shaft 13 of gas push, unify control action by bleed pressure, two piston nonreturn valve cores can be accomplished crisscross motion under gas push is controlled, thereby in realization, the staggered exhaust of working hole 10-1 and lower working hole 10-2, can accomplish stable large discharge capacity exhaust.
In order to reach better sealability, piston nonreturn valve cores in the present embodiment directed cavity 7 comprise and coaxially are assemblied on central shaft 13 core body 11 that can slide along central shaft 13, are fixedly connected on the check valve assembly 3 on core body 11 and are fixed in the slide valve assembly 4 of core body 11 front ends, along with driving slide valve assembly 4, core body 11 moves along central shaft 13, slide valve assembly 4 can stop up and open vertical chamber and laterally lead directly to the connectivity part in chamber, thereby closes and open the path between air outlet 9 and working hole 10.On the front end of described slide valve assembly 4 with scrobicular ring, described scrobicular ring is embedded with seal ring 6, relative with the seal ring wiper seal of prior art, because pressure-tight seal ring easily weares and teares, just do not reach the effect of sealing in case damaging appears in seal ring, easily leak air, and the present embodiment adopts the end face seal mode of seal ring 6 against vertical chamber, its sealability is better, and is not easy to wear, and the life-span is more permanent.
The present embodiment covers two bafflers 5 on the working hole 10 of two of up and down, its role is to: reduce noise.Certainly, in the situation that suitable, also can not be hinged with baffler 5.
