Abstract
The invention discloses a kind of flame proof safety devices of water pump for mining, including gas-accumulating tank, gas-tpe fitting, tracheae, " o " type sealing ring, spool seat piece, " o " type sealing ring, spring, spool, " o " type sealing ring and safety valve attachment base.Safety valve attachment base one end is to be threadedly coupled with water pump rotor chamber connection type, is all made of and is threadedly coupled between safety valve attachment base and spool seat piece, spool seat piece and tracheae.It is used to collect poisonous and harmful flammable explosive gas provided with a gas-accumulating tank；Spool use pyramidal structure, it is ensured that will not reverse push valve opening door, improve safety and the practicability of the invention；The invention air-tightness requirement is relatively high.The present invention has the characteristics that structure is simple, flame proof effect is preferable, high financial profit.
Description
Technical field
The present invention relates to a kind of flame proof safety devices of water pump for mining.
Background technique
The environment of coal mine is inflammable and explosive, but is had under coal mine using water pump is arrived, so being badly in need of a kind of water pump for mining
Flame proof safety device.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of flame proof safety device of water pump for mining,
The present invention has preferable safety protective effect, and high financial profit.
The technical problems to be solved by the invention are realized using following technical scheme.
A kind of flame proof safety device of water pump for mining, including gas-accumulating tank, gas-tpe fitting, tracheae, " o " type sealing ring,
Spool seat piece, " o " type sealing ring, spring, spool, " o " type sealing ring and safety valve attachment base, wherein the safety valve connects
Joint chair one end is to be threadedly coupled with water pump rotor chamber connection type, safety valve attachment base and spool seat piece, spool seat piece and gas
Threaded connection is all made of between pipe, and connection, safety valve connection between the safety valve attachment base and water pump rotor
Connection, the spool seat piece between seat and spool seat piece and the connection between tracheae need to add " o " type sealing ring, entire to fill
The air-tightness requirement set is relatively high.
The gas-accumulating tank of the sealing be for collecting gas because the gas in coal mine is poisonous and harmful, inflammable and explosive,
So cannot arbitrarily discharge, to collect, gas-accumulating tank can select oil resistant rubber capsule.It is to use between gas-accumulating tank and tracheae
Gas-tpe fitting connection, it is easy to disassemble, because gas-accumulating tank needs replacing after storing full gas.
The spool of the taper just has certain pressure and pushes spool open when the gas in water pump reaches a certain amount,
It passes the gas through tracheae and enters gas-accumulating tank, when the pressure of gas is reduced to certain value, because of the presence of spring force, spool can be answered
Position, endotracheal gas stops to one Fang Liudong of gas-accumulating tank, in turn, since spool is taper, so the pressure of gas-accumulating tank is not
Meeting reverse push valve opening core not will lead to gas leakage and cause danger, substantially increases the safety of device.
The conical surface of the spool conical surface and air inlet should seal combination, and air-tightness will centainly be got well, and otherwise can cause gas
Body leakage, causes flame proof effect that expection is not achieved, the air-tightness of whole device will centainly be got well.
Detailed description of the invention
Fig. 1 is general structure schematic diagram of the invention.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness for realizing the present invention are easy to understand, below
It in conjunction with specific embodiments and illustrates, the present invention is further explained.
As shown in Figure 1, a kind of flame proof safety device of water pump for mining, including gas-accumulating tank (10), gas-tpe fitting (9),
Tracheae (8), " o " type sealing ring (7), spool seat piece (6), " o " type sealing ring (5), spring (4), spool (3), " o " type sealing ring
(2) and safety valve attachment base (1), safety valve attachment base (1) one end is connected through a screw thread with water pump rotor chamber, when a certain amount of
Gas enters air inlet, reaches certain pressure, opens taper valve core (3), and gas enters gas-accumulating tank (10) by tracheae (8),
Due to using pyramidal structure, therefore valve will not be reversed and push open, it is ensured that safety, because gas may be poisonous and harmful inflammable
It is explosive, therefore gas-accumulating tank (10) collection need to be set, gas-accumulating tank (10) is connect with tracheae (8) by gas-tpe fitting (9), and it is easy to disassemble,
Because gas-accumulating tank (10) needs replacing after storing full gas.
