Description

A kind of guiding valve
Technical field
The utility model relates to a kind of novel guiding valve, particularly is 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 is as shown in Figure 1, and the top of discharging ball valve 3 and charging ball valve 5 sets out pellet valve guard bar 2 and charging ball valve pin 4 respectively, and its underpart is spacing by annular block plate 100.When failing material piston 8 to left movement; Discharging ball valve 3 falls under the acting in conjunction of himself gravity and piston suction, seals 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 the hopper 7 is inhaled in the material cylinder, accomplishes the suction function.When defeated material piston 8 moved right, charging ball valve 5 fell under the thrust of gravity and piston, seals supply pipe 6, and simultaneously, discharging ball valve 3 overcomes gravity and moves up under the thrust of piston, and mortar is pushed in the discharge nozzle 1.This ball-valve type mortar pump at first will overcome the deadweight of valve ball and mortar when feeding, and will pass through suction tube and will expect to suck the material cylinder, during discharging, also will pass through a plurality of bends, so the suction difficulty is big.And slurry is piled up on annular block plate 100 easily, causes defeated material to have some setbacks, even stops up.This in addition ball-valve type piston pump structure more complicated, price are also relatively more expensive.
Import S valve also can play the effect of switching-over.But the S valve can't be accomplished very little, and frequently switching-over causes both arms to damage easily, and cost is too high, is not suitable for the actual demand of Chinese medium-sized and small enterprises.
The model utility content
The purpose of the utility model provides that a kind of cost is low, the guiding valve of long service life.
Adopt following technological scheme in order to solve the problems of the technologies described above: 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; Said valve body is provided with through hole at the channel position with respect to carrier pipe, and said spool is made up of warehouse that can in valve body, move and the baffle plate that is fixed on sleeve ends.
Said 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 said baffle plate and the diameter of through hole adapt.
Said 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 said 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 said power plant for being connected with sleeve.
In the utility model, guiding valve is made up of the power plant of valve body, spool and promotion valve core movement, and spool is by constituting with corresponding warehouse of carrier pipe and baffle plate; Simple in structure; Cost is lower, and suction process and defeated material process need not passed through a plurality of bends, have improved defeated material efficient greatly.

Embodiment
Embodiment 1
Like Fig. 2, shown in Figure 3, the guiding valve in the utility model is positioned at the downstream side of the piston of reciprocating pump, and it comprises the power plant of valve body 11, spool and promotion valve core movement.Above-mentioned valve body 11 is provided with through hole at the channel position with respect to carrier pipe, and the pipe diameter of the diameter of through hole and carrier pipe 9 adapts.Above-mentioned spool is made up of sleeve that can in valve body, move 14 and the baffle plate 13 that is fixed on sleeve 14 ends; The diameter of bore of above-mentioned sleeve 14 matches with through-hole diameter; Baffle plate 13 vertically extends along outer, sleeve 14 bottom; Its baffle plate 13 shapes can be rectangular flat, also can be sphere, elliposoidal or the like.
In the present embodiment, guiding valve is positioned at the piston downstream side of single cylinder piston pump.In this case, baffle plate 13 is fixed in sleeve 14 ends one side, and the length of baffle plate 13 and the diameter of through hole adapt.Its power plant are the hydraulic push rod device 12 that is connected with sleeve 14, and specifically the push rod of hydraulic push rod device is connected with sleeve 14, but under the drive of oil hydraulic cylinder move left and right.Need to prove that hydraulic push rod device 12 can be positioned at a side of sleeve 14, also can be positioned at the both sides of sleeve 14.
The working procedure of guiding valve is in the present embodiment: as shown in Figure 2, guiding valve is arranged on single cylinder piston pump piston downstream side, during the downward pusher of piston 10; Under the effect of hydraulic push rod device 12, spool slides, and makes sleeve 14 coaxial with carrier pipe 9; Be that sleeve 14 is connected carrier pipe 9, the defeated material in piston storehouse.As shown in Figure 3, piston 10 is upwards taken out when material, and under the effect of hydraulic push rod device 12, spool slides, and makes sleeve 14 and carrier pipe 9 disalignments, i.e. baffle plate 13 closed carrier pipes 9, and material is taken out in the piston storehouse.
