Abstract
The utility model relates to a safety valve of warehouse which is on the powder pneumatic conveyor pipe. The technic proposal of the utility model is that: the upper spiral marking of the valve body (5) is connected with the cylinder body (1), the lower spiral marking is connected with the short section (13), the centre is provided with the excreting entrance and is connected with the rubber pipe joint (6); the inner spiral marking of the upper end of the valve body is connected with the piston (4); the sealed device is arranged in the cavity which is composed of the valve body (5) and the cylinder body (1), which is characterized in that: the piston (4) is connected with the sealed device by the core pin (3). The beneficial effects are that: the utility model overcomes the flaw that the used spring safety valve is always obstructed and is out of the order in the powder pneumatic conveyor storage process; when using the safety valve, the utility model can improve the reliability and the safety of the safety valve, can effectively prevent particle material leaking out, the utility model is beneficial to protect the environment, and is easy to operate.
Description
One, technical field:
The utility model relates to a kind of safety valve on powder pneumatic carrier line, and is particularly a kind of to the strength on the transfer line is carried or pressure store limits grey storehouse safety valve.
Two, background technique:
The powder strength is carried the safety valve that uses in the storage process at present, all is spring, and valve body does not go deep in the pipeline, and the problem of existence is: the one, and often cause safety valve to stop up; The 2nd, spring changes because of elasticity and spring and interior wall friction cause safety valve to use ineffective problem also to take place often.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and providing a kind of can not only limit strength conveying or pressure store, and can prevent that powder from stopping up the pressure transmission passage and causing the malfunctioning grey storehouse safety valve of safety valve.
Its technological scheme is: valve body (5) upper end screw thread connecting cylinder body (1), the lower end pipe nipple (13) that is threaded, and the centre is provided with outfall and connects rubber hose coupling (6); Valve body (5) upper end internal whorl connects piston (4); Seal arrangement is arranged in the inner chamber of valve body (5) and cylindrical shell (1) composition, and it is characterized in that: described piston (4) connects seal arrangement by pin (3).
More concrete is: described seal arrangement comprises: nut (2) is by the screw rod that is threaded (7) upper end, and screw rod (7) passes seal (8), plug (10) pad (11) and pressure cap (12) by being threaded togather.
Preferable technological scheme is: described piston (4) connects described screw rod (7) upper end by pin (3).
The beneficial effects of the utility model are: overcome the powder strength and carry the Direct spring loaded safety valve that uses in the storage process often to stop up malfunctioning shortcoming; Can in safety valve uses, improve reliability, the Security of safety valve, can prevent effectively that the powder material from leaking, be of value to environmental protection, and simple to operate.
Four, description of drawings:
Accompanying drawing 1 is the structural drawing that partly cuts open of the present utility model.
Figure middle cylinder body 1, nut 2, pin 3, piston 4, valve body 5, rubber hose coupling 6, screw rod 7, seal 8, seal ring 9, plug 10, pad 11, pressure cap 12, pipe nipple 13
Five, embodiment:
In conjunction with the accompanying drawings, the utility model will be further described:
Its technological scheme is: valve body 5 upper end screw thread connecting cylinder bodies 1, the lower end pipe nipple 13 that is threaded, and the centre is provided with outfall and connects rubber hose coupling 6; Valve body 5 upper end internal whorls connect piston 4; In the inner chamber that valve body 5 and cylindrical shell 1 formed following assembly is set: nut 2 is by screw rod 7 upper ends that are threaded, screw rod 7 passes seal 8, seal ring 9, plug 10, pad 11 and pressure cap 12 by being threaded togather screw rod 7 upper ends that described piston 4 connects by pin 3.
Working principle and process are as follows:
Safety valve is installed on the powder pneumatic carrier line, the end of valve is by pipe nipple 13 connecting lines, and remove the spring that causes safety valve to stop up easily, use the pin pilot pressure, when strength conveying or pressure store are higher than specified value, pin is cut off, it is up that air pressure promotes pressure cap, pad, plug, seal, seal ring, screw rod nut, and when piston stroking upward during to outfall top that rubber hose coupling 6 connects, gas and dust are drained, pressure descends, until stopping drainage; At last, check the superpressure reason, change pin and recover normal use.
Claims (3)
1, a kind of grey storehouse safety valve, valve body (5) upper end screw thread connecting cylinder body (1), the lower end pipe nipple (13) that is threaded, the centre is provided with outfall and connects rubber hose coupling (6); Valve body (5) upper end internal whorl connects piston (4); Seal arrangement is arranged in the inner chamber of valve body (5) and cylindrical shell (1) composition, and it is characterized in that: described piston (4) connects seal arrangement by pin (3).
2, grey storehouse according to claim 1 safety valve, it is characterized in that: described seal arrangement comprises: nut (2) is by the screw rod that is threaded (7) upper end, and screw rod (7) passes seal (8), plug (10) pad (11) and pressure cap (12) by being threaded togather.
3, grey storehouse according to claim 1 and 2 safety valve is characterized in that: described piston (4) connects described screw rod (7) upper end by pin (3).
