Abstract
The utility model provides a novel vessel valve; the upper valve body is arranged on an upper end mouth of the valve body; a cavity of the valve body arranged on the below end of the upper valve body is respectively provided with a pressed ring and a supper cover; the support cover is arranged on a cone desk of the inner cavity for the valve body; a cross channel of the pressed ring is communicated with a fan-out mouth of the valve body; the inner cavity of the upper valve body is provided with a piston and a piston bar; the pressed ring and the support cover are connected with a slide valve of the inner cavity device; the slide valve of the inner cavity device together with a valve core and a return spring make the piston be connected with the piston bar and the valve core through a center hole passing through the pressed ring and the slide valve; the valve core and the return spring are matched and connected with the slide valve of the inner cavity device. A block loop is arranged on the terminal of the slide valve; a cut-down driving organ for the valve is arranged on the top end of the upper valve body. By using of the machinery force or the air-pressure force, no matter during the releasing process or after the releasing process, the valve can be started on or off directly; the design structure can overcome the shortcoming that the valve can not be closed by a one-off releasing. A plurality of seals in the valve can lead to much better in the sealing performance with the increasing of the pressure. So no matter in the low pressure situation or in the high pressure situation, the sealing performance for the valve is always much more reliable. The valve is suitable to be widely used with safe and reliable.
Description
Technical field
The utility model belongs to the fire-fighting fire-extinguishing equipment parts, and particularly a kind of fire-fighting fire-extinguishing equipment and utensil working pressure discharge, carry and control the novel container valve of keying usefulness smaller or equal to the pressurized gas of 20MPa, the liquid of non-aggressive medium.
Background technique
Traditional fire-fighting fire-extinguishing equipment mostly is diaphragm-type or pneumatic back pressure type with the container valve structure, and the diaphragm-type valve opening of one is to puncture seal membrane by the gas-powered knife to realize.Yet the defective that this structure exists is: only can once open and can not close again, so can not reuse, must change diaphragm at any time, and its working pressure optimum range be little.Sealing effect is poor during the low working pressure of its pneumatic back pressure type valve of two, also only can once open and can not close.In addition, when taking place to stop up, gas circuit in the valve can cause the drawback that reliably to open.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel container valve, directly open or throttle down with machinery or atmospheric pressure, valve is reused, solved valve and once discharged the problem that to close, and made valve its sealability under low pressure and high pressure conditions all reliable.
The technical solution of the utility model is: a kind of novel container valve is characterized in that: it is made up of valve start or stop driving mechanism, piston and piston rod, upper valve body, starting bar, pressure ring, valve body, guiding valve, spool, back-up ring, spring and supporting sleeve; The upper end-hole of upper valve body device valve body, the body cavity of upper valve body lower end are installed the supporting sleeve that pressure ring and frame are loaded on body cavity taper platform successively, and the horizontal through hole of pressure ring is communicated with the valve body delivery outlet; Its upper valve body endoluminal means piston and piston rod, pressure ring and supporting sleeve are connected the endoluminal means guiding valve, spool and return spring that guiding valve endoluminal means and its slit are connected, return spring is to rely on pressed spool in the inner chamber of guiding valve with the supporting sleeve, by the starting bar in pressure ring and guiding valve center hole piston and piston rod and spool is connected; Guiding valve port means back-up ring; The valve start or stop driving mechanism of driven plunger and piston rod is arranged on the upper valve body top.
Above-mentioned valve start or stop driving mechanism can adopt pneumatic drive mechanism driven plunger and piston rod work.
Above-mentioned valve start or stop driving mechanism is that starting handle is hinged according to bearing pin and upper valve body, and the work of starting handle piston rod designs according to cam machinery.
Between above-mentioned pressure ring and valve body, between pressure ring and guiding valve, guiding valve and valve core chamber be provided with sealing gasket respectively, make valve output a chamber and import exclusion seal between the c chamber.
Above-mentioned input c chamber side is provided with the diaphragm type relief valve.
The beneficial effects of the utility model are: utilize no matter mechanical force or atmospheric pressure are all can directly open or throttle down in discharging or after discharging, solved valve and once discharged the problem that can not close.The multiple-sealed big more sealability of its pressure that makes of valve is good more.So this valve no matter sealability of low pressure and high pressure conditions is all reliable.This valve optimum range is wide, and safe and reliable.
Description of drawings
Fig. 1 structural representation of the present utility model.
Among the figure: 1 starting handle, 2 pistons and piston rod, 3 upper valve bodies, 4 starting bars, 5 pressure rings, 6 valve bodies, 7 sealing gaskets, 8 sealing gaskets, 9 sealing gaskets, 10 guiding valves, 11 spools, 12 back-up rings, 13 springs, 14 supporting sleeves, 15 diaphragm type relief valves.
Embodiment
Specify the utility model below in conjunction with drawings and Examples.
A kind of novel container valve, it is made up of starting handle 1, piston and piston rod 2, upper valve body 3, starting bar 4, pressure ring 5, valve body 6, sealing gasket 7, sealing gasket 8, sealing gasket 9, guiding valve 10, spool 11, back-up ring 12, spring 13 and supporting sleeve 14; The upper end-hole of upper valve body 3 device valve bodies 6, valve body 6 inner chambers of upper valve body 3 lower ends are installed the supporting sleeve 14 that pressure ring 5 and frame are loaded on body cavity taper platform successively, and the horizontal through hole of pressure ring 5 is communicated with valve body 6 delivery outlets; Its upper valve body 3 endoluminal means pistons and piston rod 2, pressure ring 5 and supporting sleeve 14 are connected endoluminal means guiding valve 10, six sides and its slit were connected outside guiding valve 10 endoluminal means had spool 11 and return spring 13, return spring 13 serves as to rely on pressed spool 11 in the inner chamber of guiding valve 10 with supporting sleeve 14, by the starting bar 4 in pressure ring 5 and guiding valve 10 center holes piston and piston rod 2 and spool 11 is connected; Guiding valve 10 port means back-up rings 12; The starting handle 1 of driven plunger and piston rod 2 is hinged according to bearing pin and upper valve body 3, and the work of starting handle 1 piston rod designs according to cam machinery.Perhaps on upper valve body, had the source of the gas input hole by external pneumatic drive mechanism piston and piston rod work.6 of above-mentioned pressure ring 5 and valve bodies, pressure ring 5 and 10 in guiding valve, guiding valve 10 and 11 of spools are provided with sealing gasket 7 respectively, make exclusion seal when being in closed condition between valve output a chamber and the input c chamber.Above-mentioned input c chamber side is provided with diaphragm type relief valve 15, and when the pressure superpressure, the decompression protection effect is played in the diaphragm explosion, makes the valve usability safe and reliable.
Working principle: move starting handle 1, utilize the cam principle to drive piston and piston rod 2, by starting bar 4 power transmission spools 11, and spool 11 makes it to move down for guiding valve 10 by back-up ring 12 power transmissions, output a chamber and input c chamber UNICOM, valve opening.Because the effect of return spring 13 makes on guiding valve 10 and the spool 11 and moves, simultaneously, the power on guiding valve 10 and the spool 11 of acting on of the air pressure P in the c chamber is also impelled on guiding valve 10 and the spool 11 and is moved, and then sealing gasket 7 and 8 is compacted, make valve a chamber and c chamber be cut off sealing, valve closing.
