Abstract
A liquid return shutoff valve comprises a valve body, a valve seat, a valve core, a compression spring and a valve sleeve. The valve sleeve is mounted inside the valve body, water through holes are evenly peripherally distributed at one end of the valve sleeve and communicated with communication holes of a pump case, the valve core is mounted on the valve seat which is mounted outside the valve sleeve, and 45-degree chamfers are arranged at contacted positions of the valve seat and the valve core. The compression spring is arranged between the valve core and the valve sleeve, and internal threads are positioned inside the communication holes at two ends of the valve seat and used for connecting the pump case with a liquid return pipeline of a pump station. The liquid return shutoff valve is simple in structure and convenient in manufacturing. When an emulsification pump is in normal operation, pump station returned liquid enters a breaker through a high-pressure rubber pipe, and the valve core is pushed open by pressure of the returned liquid, so that the valve core and the valve seat are separated and the liquid normally enters the pump case. When the emulsification pump needs to be closed and maintained, the valve core and the valve seat are closed under the action of the compression spring inside the liquid return shutoff valve, so that the liquid in the pump case cannot flow out and pump station maintenance is facilitated.
Description
Technical field
The utility model relates to the special-purpose time liquid cutout valve of a kind of emulsion power pack pump box liquid return pipe.
Background technique
At present the liquid return pipe in the emulsion power pack pump box is welded into iron pipe, and the height of the other end of iron pipe water outlet surpasses the horizontal plane in the pump box, thus when the maintenance pumping plant, lay down pumping plant and pump box be connected sebific duct the time, the water in the pump box can flow out.When using a period of time, because the aqueous corrosion property in the mine is big, the liquid return pipe corrosion fracture in the pump box in the down-hole.Cause maintenance during pumping plant a large amount of water in pump box, flow out, till one the case current are done, bring difficulty to maintenance.And when the overhaul of pumping plant gug, when wanting to be former state to liquid return pipe repair welding again, do not accomplish, because of 1/2nd places in the pump box separate with iron plate, do not advance the people down, so can't weld, bring difficulty to maintenance. at all
Summary of the invention
The purpose of the utility model is a kind of time liquid circuit breaker of design, connects on pump box, to solve the problem that existing technology exists.
Realize that the technological scheme that the utility model purpose is taked is: make one and return the liquid circuit breaker; It is made up of valve body, valve seat, spool, pressure spring, valve pocket; Valve pocket is installed in the valve body, and valve pocket one end periphery is evenly equipped with the water port, and each water port all is connected with the pump box intercommunicating pore; Valve seat is installed in the valve pocket outside, and spool is installed on the valve seat, and respectively there is one 45 degree chamfering valve seat and spool contacting point; Between spool and valve pocket, be provided with a pressure spring; The intercommunicating pore at valve seat two ends all has internal thread, is respectively applied for to connect pump box and pumping plant liquid return pipe road.
The good effect of the utility model is: simple in structure, and convenient the manufacturing; When emulsification pump ran well, pumping plant returned liquid and gets into circuit breaker through high-pressure rubber pipe, pushed spool open through the pressure that returns liquid water, and spool and valve seat are separated, and liquid normally gets into pump box.When emulsification pump need overhaul, when closing emulsification pump, under the pressure spring effect of returning in the liquid circuit breaker, close spool and valve seat, the liquid that can not in the pump box is overflowed, convenient to the pumping plant maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Shown in accompanying drawing, it is made up of valve body 2, valve seat 3, spool 4, pressure spring 6, valve pocket 5, and valve pocket 5 is installed in the valve body 2, and valve pocket 5 one end peripheries are evenly equipped with water port 7, and each water port 7 all is connected with pump box intercommunicating pore 8; Valve seat 3 is installed in valve pocket 5 outsides, and spool 4 is installed on the valve seat 3, and valve seat 3 respectively has one 45 degree chamfering with spool 4 contacting points; Between spool 4 and valve pocket 5, be provided with a pressure spring 6; The intercommunicating pore 1,8 at valve seat 3 two ends all has internal thread, is respectively applied for to connect pumping plant liquid return pipe road and pump box.
When emulsification pump ran well, pumping plant returned liquid and gets into circuit breaker through high-pressure rubber pipe, pushed spool 4 open through the pressure that returns liquid water, and spool 4 and valve seat were opened in 3 minutes, and liquid normally gets into pump box.When emulsification pump need overhaul, when closing emulsification pump, under the effect of returning the pressure spring 6 in the liquid circuit breaker, close spool 4 and valve seat 3, the liquid that can not in the pump box is overflowed, convenient to the pumping plant maintenance.
