Description
Technical field
The present invention relates to a kind of novel guiding valve, particularly be mainly used in the guiding valve of piston mortar pump pumping material.
Background technique
At present, the pumping mortar generally adopts the ball-valve type mortar pump, and as shown in Figure 1, the top of discharging ball valve 3 and charging ball valve 5 sets out respectively pellet valve guard bar 2 and charging ball valve pin 4, and its underpart is spacing by annular block plate 100.When conveying piston 8 during to left movement, discharging ball valve 3 falls under the acting in conjunction of himself gravity and piston suction, seal discharge nozzle 1, simultaneously, 5 of charging ball valves overcome gravity and move up under the suction of piston, open supply pipe 6, the mortar in hopper 7 is inhaled in the material cylinder, completes the suction function.When conveying piston 8 moved right, charging ball valve 5 fell under the thrust of gravity and piston, sealed supply pipe 6, and simultaneously, discharging ball valve 3 overcomes gravity and moves up under the thrust of piston, and mortar is pushed in discharge nozzle 1.This ball-valve type mortar pump when feeding, at first will overcome the deadweight of valve ball and mortar, and will will expect to suck the material cylinder through suction tube, during discharging, also will pass through a plurality of bends, so the suction difficulty is large.And slurry is easily piled up on annular block plate 100, cause conveying to have some setbacks, and even stops up.This ball-valve type piston pump structure more complicated in addition, price is also more expensive.
Import S valve also can play the effect of commutation.But the S valve can't be accomplished very little, and frequently commutation easily causes both arms to damage, and cost is too high, is not suitable for the actual demand of China SMEs.
Summary of the invention
The purpose of this invention is to provide that a kind of cost is low, the guiding valve of long service life.
In order to solve the problems of the technologies described above by the following technical solutions: a kind of guiding valve, be positioned at the downstream side of the piston of reciprocating pump, the power plant that comprise valve body, spool and promotion valve core movement, described valve body is provided with through hole at the channel position with respect to carrier pipe, and described spool is comprised of the warehouse that can move in valve body and the baffle plate that is fixed on sleeve ends.
Described guiding valve is positioned at the piston downstream side of single cylinder piston pump, and its baffle plate is fixed in sleeve ends one side, and the length of described baffle plate and the diameter of through hole adapt.
Described guiding valve is positioned at the piston downstream side of duplex piston pump, and its baffle plate is to be fixed in two symmetrical baffle plates of sleeve ends both sides, and the diameter of described baffle length and through hole adapts.
The diameter of above-mentioned through hole and the pipe diameter of carrier pipe adapt.
The hydraulic push rod device of described power plant for sleeve, being connected.
In the present invention, guiding valve consists of the power plant of valve body, spool and promotion valve core movement, and spool consists of the warehouse corresponding with carrier pipe and baffle plate, simple in structure, cost is lower, and suction process and conveying process need not passed through a plurality of bends, have greatly improved conveying efficiency.
