Abstract
The utility model relates to a pressure discharge valve capable of protecting a shallow sea small-bore metal strip plastic composite hose, which comprises a valve mounting sleeve (1), a valve coat (2), a valve core (3), a valve top cover (4), a spring (5) and a sealing ring (6). In the process of transmitting a high-pressure medium by the hose, when the pressure of the medium is higher than the rated numerical value of the spring in the pressure discharge valve, the pressure pushes the valve core to compress the spring so as to make the valve core move, the sealing ring leaves the sealing surface of the valve coat along with the movement of the valve core, and at this time, the penetrative pressure medium is extruded out from a gap between the sealing ring and the sealing surface of the valve coat so as to maintain the penetrative medium pressure of a metal reinforced layer of the hose below the rated pressure. When the penetrative medium pressure is smaller than the rated numerical value of the spring, the valve core is pushed back to the sealing surface of the valve coat due to the effect of the deformation recovery force of the spring to form a closed state. The utility model has the advantage of solving the adverse factor of penetration on the hose when the high-pressure medium is transmitted.
Description
Technical field
The utility model belongs to the innovation of ocean flexible pipe protective gear.
Background technique
The mode of movement of ocean medium (oil, gas, water etc.) has two kinds of steel pipe and flexible pipes, and steel pipe has certain opposing impact, wearing and tearing ability, characteristics such as good airproof performance, cost of material price are lower.Though the offshore construction cost is higher, but still be widely used in the ocean engineering field.And flexible pipe is relative higher in aspect expenses such as its cost of material and manufacturing process, but characteristics such as that it has is anticorrosive, easy construction also progressively the ocean engineering field that is applied to, the existing employing in the short-range medium in seabed (G﹠W) is carried at present.
Summary of the invention
Because the characteristics on hose construction structure and the manufacturing process, carry in high-pressure medium (G﹠W) process at flexible pipe, the too high meeting of pressure medium causes the infiltration of Lining Hose layer, can continue to produce infiltration to the separation layer of flexible pipe behind the pressure medium infiltrate metal enhancement layer, until flexible pipe is damaged.In order to prevent that the high-pressure medium infiltration from causing damage to flexible pipe, the utility model proposes a kind of purge valve of protecting flexible pipe.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of purge valve of protecting the shallow sea small-diameter steel strip-plastic composite hose, form by valve installation sleeve, valve overcoat, valve stamen, valve top cover, spring and seal ring six parts.Carry in the process of high-pressure medium at flexible pipe, when pressure medium is higher than the rating number of purge valve inner spring, pressure promotes the valve stamen spring is compressed, thereby make the valve stamen move, seal ring leaves the sealing surface of valve overcoat along with moving of valve stamen, this moment, the pressure medium of infiltration was just extruded from gap between the sealing surface of seal ring and valve overcoat, and the permeating medium pressure of flexible pipe metal enhancement layer is remained under the rated pressure.When the pressure medium of infiltration during less than the rating number of hydrovalve medi-spring, because the deformation restoring force effect of spring is passed the sealing surface that is back to the valve overcoat with the valve stamen again, form closed state, go on so repeatedly.
The beneficial effects of the utility model are that flexible pipe pressure medium is in the course of the work remained under the constant state, have solved the unfavorable factor that the high-pressure medium infiltration causes flexible pipe.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 2 is the opening state of purge valve.
1-valve installation sleeve wherein; 2-valve overcoat; 3-valve stamen; 4-valve top cover; The 5-spring; The 6-seal ring
Embodiment
Among Fig. 1, purge valve is a closed state, and pressure medium infiltration inside liner is to the metal enhancement layer, and before pressure did not reach the porous spacer layer, pressure medium infiltrate metal enhancement layer was to purge valve.Purge valve is made up of installation sleeve 1, valve overcoat 2, valve stamen 3, valve top cover 4, spring 5, seal ring 6 six parts, and spring 5 has specified numerical value, and this numerical Design is 0.5MPa, is lower than the seepage pressure of separation layer.
Among Fig. 2, purge valve is an opening state, when the pressure of metal enhancement layer infiltration reaches greater than design pressure 0.5MPa, pressure promotes 3 pairs of springs 5 of valve stamen and compresses, make spring 5 that deformation take place, thereby make valve stamen 3 move, seal ring 6 leaves the sealing surface of valve overcoat 2 along with moving of valve stamen 3, this moment, the pressure medium of infiltration was just extruded from gap between the sealing surface of seal ring 6 and valve overcoat 2, and the permeating medium pressure of flexible pipe metal enhancement layer is remained under the rated pressure.When the pressure medium of infiltration during,, form closed state because the deformation restoring force effect of spring 5 is passed the sealing surface that is back to valve overcoat 2 with valve stamen 3 again less than 0.5MPa.So repeatedly, thereby guaranteed that permeating medium pressure all the time in specified scope, avoided the effect of pressure to the flexible pipe separation layer, effectively protected flexible pipe.
In addition, purge valve on hose coupling, be arranged as annular uniform layout, 3 of present uniform one-tenth, angle is 120 °.Can be circular layout into 6 or 8 according to actual demands of engineering.
Claims (3)
1. can protect the purge valve of shallow sea small-diameter steel strip-plastic composite hose to form for one kind by valve installation sleeve, valve overcoat, valve stamen, valve top cover, spring and seal ring six parts; it is characterized in that the valve stamen by spring deformation, makes the sealing surface of seal ring and valve overcoat be in closure or opening state.
2. a kind of purge valve of protecting the shallow sea small-diameter steel strip-plastic composite hose according to claim 1 is characterized in that in its structure spring being installed, and this spring can design specified numerical value.
3. a kind of purge valve of protecting the shallow sea small-diameter steel strip-plastic composite hose according to claim 1, what it is characterized in that purge valve is arranged as annular uniform layout on hose coupling, can uniformly be arranged to 3, and angle is 120 degree; 6, angle is 60 degree; 8, angle is 45 degree.
