The described low high resistant valve of letting out comprises valve body, flap, spring and sealing gasket; This valve body axially offers along it the flap chamber and the spring cavity that are connected, the footpath, chamber of this spring cavity is less than the footpath, chamber in described flap chamber, the outer end separately of this flap chamber and spring cavity is respectively equipped with water inlet and delivery port, described flap is arranged in described flap chamber movably, between the sidewall in this flap and flap chamber, left water seam hole, described spring supports between at the bottom of the chamber of described flap and spring cavity, and described sealing gasket is embedded in the corresponding surface of described valve body on the side of described spring cavity one side.
The madial wall in described flap chamber is concaved with a back-up ring groove, in this back-up ring groove, is embedded with a circlip for hole, and this circlip for hole is positioned between described water inlet and described flap.
The corresponding surface of described flap has one for the sheathed projection of described spring to one-body molded on the side of described spring cavity.
On the internal chamber wall that the correspondence in described flap chamber is accepted mutually with described spring cavity, convex with the annular flange flange corresponding with described sealing gasket.
On described valve body lateral wall, be inlaid with a sealing ring.
Adopt after such scheme, this Novel photo is for the beneficial effect of prior art: a low high resistant valve of letting out is installed on the big gun base of fire water monitor, when being full of press water and hydraulic pressure in the pipeline of big gun body higher than when setting value, the low flap of letting out high resistant valve under hydraulic pressure in closed condition.Water cannon is closed after using, and also has the remaining water of part in big gun body, when gun platform chamber pressure is reduced to lower than setting value, the low high resistant valve auto-action of letting out is in opening, remaining water in water cannon inner chamber is discharged via the low high resistant valve of letting out, thereby plays good antifreeze effect, guarantees that fire water monitor reliably uses.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of low high resistive fire water monitor of letting out, and as shown in Figure 1, comprises the big gun body 1 and the big gun base 2 that are connected with up and down, and the below of big gun base 2 is connected with water inlet pipe 3.The main improvement of this case fire water monitor is, on the pipe sidewall of big gun base 2, (on the sidewall of the pipeline section being connected at corresponding and big gun body 1 particularly) offers an installing port 21, and a low high resistant valve 4 of letting out is installed in this installing port 21.
In prior art, exist and have a low low high resistant valve arrangement of letting out of letting out high resistant effect of hydraulic pressure, this case is according to the low mounting means of high resistant valve 4 on installing port 21 of letting out, the low high resistant valve 4 of letting out that specialized designs one adapts.Shown in Fig. 2-3, the low high resistant valve 4 of letting out comprises valve body 41, flap 42, sealing gasket 43 and spring 44.Valve body 41 axially offers along it the flap chamber 411 and the spring cavity 412 that are connected, and the footpath, chamber of this spring cavity 411 is less than the footpath, chamber in flap chamber 412.The outer end separately of flap chamber 411 and spring cavity 412 is respectively equipped with water inlet 413 and delivery port 414.Flap 42 is arranged in flap chamber 411 movably, and the lobe edge 421 that flap 42 contacts with flap chamber 411 is irregular non-circular edge, between the sidewall in flap 42 and flap chamber 411, leaves water seam hole.Spring 44 flexibly supports between at the bottom of the chamber of flap 42 and spring cavity 412, and sealing gasket 43 is embedded in the corresponding surface of flap 1 on the side of spring cavity 412 1 sides.
Low operation principle of letting out high resistant valve 4 is as follows.In the time being full of press water and hydraulic pressure higher than setting value (such as 0.1Mpa) in the pipeline of big gun body 1, Water Pressure is in flap 42 Compress Spring 44, water pressure pushing flap 42 moves toward spring cavity 412 directions, until on the internal chamber wall that the correspondence that sealing gasket 43 is resisted against flap chamber 411 tightly and spring cavity 412 are accepted mutually, sealing function by sealing gasket 43 with described internal chamber wall, delivery port 414 place's closed conditions.After using, water cannon closes, in big gun body 1, also there is the remaining water of part, when gun platform 2 chamber pressures are reduced to lower than setting value, recover by spring 44 elasticity, thereby drive flap 42 and sealing gasket 43 mobile toward spring cavity 412 in the other direction, the low high resistant valve 4 of letting out recovers opening automatically, and the remaining water in big gun body 1, via water inlet 413, flap chamber 411, mistake water seam hole, spring cavity 412, is finally discharged from delivery port 414.
Preferably, the madial wall in flap chamber 411, in establishing and be concaved with a back-up ring groove 415 near water inlet 413 places, is embedded with a circlip for hole 45 in back-up ring groove 415, and this circlip for hole 45 is positioned between water inlet 413 and flap 42, plays to keep off and holds flap 42 and act on.
Preferably, the corresponding surface of described flap 42 has a projection 422 to one-body molded on the side of spring cavity 412, for sheathed its location that is beneficial to of spring 44.
Preferably, on the internal chamber wall that the correspondence in described flap chamber 411 and spring cavity 412 are accepted mutually, convex with annular flange flange 416, the setting corresponding with sealing gasket 43 of this annular flange flange 416, the two enhanced leaktightness performance that cooperatively interacted.
Preferably, on described valve body 41 lateral walls, be inlaid with a sealing ring 46, for strengthening low sealing of letting out between high resistant valve 4 and installing port 21.
The foregoing is only this novel preferred embodiment, all equalizations of doing with this novel claim scope change and modify, and all should belong to the scope of this novel claim.
