Detailed Description
The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.
The specific embodiment is as follows: the utility model provides a safe gas-liquid linkage ball valve, includes valve body 1, be provided with air inlet chamber 3 and chamber 7 of giving vent to anger on the valve body 1, valve body 1 is inside to be provided with intercommunication air inlet chamber 3 and chamber 7 of giving vent to anger's air vent 2, valve body 1 upper portion is provided with cylinder body 6, the upper and lower both ends of cylinder body 6 are the opening, sliding seal is the sliding seal is connected with shutter 4 in the cylinder body 6, and sliding seal is both can both slide relatively and can keep sealedly, shutter 4 includes piston body 41 that is connected with cylinder body 6 sliding seal, and the outer circumference of piston body 41 is provided with the sealing washer, piston body 41's bottom is provided with piston rod 42, piston rod 42's bottom is provided with the top 43 that can block up air vent 2, piston body 41's cross-sectional area is greater than top 43 to upwards top under the effect of natural air pressure, piston body 41's top is provided with drum 44, the both sides of drum 44 are provided with triangle-shaped breach 45, cylinder body 6 top is provided with guard 5, guard 5 between guard 5 top and piston body 41 and piston body 8 are provided with first spring 8, and the spring 45 can be blocked down when the device that the spring 45 is blocked down to certain clamp can be moved to the device.
Further, the clamping device comprises blind holes 51 arranged at two sides of the shield 5, a clamping head 10 which is slidably connected with the blind holes 51 and can be inserted into the notch 45, and a second spring 9 which is arranged in the blind holes 51 and can push the clamping head 10. The cross section of the front end of the chuck 10 is triangular and matched with the notch 45.
Further, the upper portion of the vent hole 2 is in a truncated cone shape, the diameter of the upper end of the truncated cone is larger than that of the lower end of the truncated cone, and the lower portion of the plug 43 is also in a truncated cone shape, so that the sealing performance is good.
Further, a deformation sealing layer is provided on the side surface of the plug 43, and the deformation sealing layer may be a polytetrafluoroethylene layer, so that the tightness is further improved.
When the chuck 10 and the notch 45 are configured such that the bottom surface is a flat surface and the upper surface is a slant surface (the flat surface is a surface perpendicular to the moving direction of the shutter 4, and the slant surface is a surface not perpendicular to the moving direction of the shutter 4), the cylinder 44 does not substantially continue to move upward when the chuck 10 is inserted into the notch 45 when the cylinder 44 moves upward. When the chuck 10 and the notch 45 are both inclined surfaces, in some cases, when the cylinder 44 moves upward and the chuck 10 is inserted into the notch 45, the cylinder 44 may continue to move upward so that the chuck 10 is removed from the notch 45, and at this time, the cross-sectional area of the piston body 41 is required to be larger than the cross-sectional area of the upper end opening of the cylinder body 6, so that the piston body 41 is blocked to prevent the excessive rise of the shutter 4. Of course, the top of the chuck 10 and the notch 45 cannot be planar.
Working principle: when the safety gas-liquid linkage ball valve is used, the gas inlet cavity 3 is connected with a natural gas inlet pipeline, the gas outlet cavity 7 is connected with a gas pipeline for a user, the opening and closing piece 4 rises under the action of natural gas pressure in the natural gas inlet pipeline, the plug 43 is separated from the vent hole 2, the valve is in an open state, and when the opening and closing piece 4 rises a certain distance, the clamping head 10 is clamped into the notch 45; under the condition that the natural gas pipeline leaks gas, the pressure in the natural gas pipeline drops, when the degree of the pressure drop of the natural gas is smaller, the opening degree of the valve can not be reduced, the air consumption of a user can not be greatly reduced, when the pressure drop is to a certain degree, the downward thrust of the first spring 8 to the opening and closing piece 4 is larger than the sum of the supporting force of the clamping device to the opening and closing piece 4 and the upward thrust of the natural gas to the opening and closing piece 4, at the moment, the opening and closing piece 4 moves downwards, the plug 43 blocks the vent hole 2, and the valve is in a closed state.
It is to be understood that the above-described embodiments of the present utility model are merely illustrative of or explanation of the principles of the present utility model and are in no way limiting of the utility model.
