Abstract
The utility model relates to a valve for a polyurethane filling machine. A feed inlet is communicated with a feed back port through a straight through groove which is arranged on a valve core. The front part of the valve core is provided with a cone and a material clearing rod, the cone is cooperated with a seal line arranged in a valve hole, and the material clearing rod is cooperated with a material filling port. In this way, the difficulty of part manufacture is reduced greatly, the valve has good sealing performance, and the valve can not be blocked. The valve which is improved has simple structure and reliable motion, and the utility model can be used for many occasions, such as polyurethane sole filling, etc.
Description
The utility model relates to a kind of valve, particularly is applied to the valve on the polyurethane bottler placer.
This valve is positioned on the material feeding mouth of polyurethane bottler placer head, is used to control the keying that two groups of raw materials enter mixing chamber.Existing valve has two kinds on ball valve type and plunger valve type, and ball valve type is owing to adopt soft seal, wearing and tearing easily; Plunger valve adopts clearance seal, and difficulty of processing is big, poor sealing performance and obstruction easily.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of good seal performance is provided, and is easy to process, can not stop up, and moves simple and reliable polyurethane bottler placer valve.
Technical solutions of the utility model are as follows: new polyurethane bottler placer valve comprises valve body and spool, it in the valve body valve body hole, valve body hole is provided with material feeding port, material feeding mouth and feedback outlet from front to back successively, material feeding mouth and material feeding port and feedback outlet communicate, it is characterized in that spool and valve body hole cooperate, and can in valve body hole, axially move; Be provided with a direct through groove in the spool, material feeding mouth communicates with feedback outlet by direct through groove; The spool front portion is provided with cone and residue-removing rod, and cone cooperates with potted line in the valve opening, and residue-removing rod cooperates with material feeding port.
Owing to adopt technique scheme, on spool, offer direct through groove, process more convenient; Cooperate with the valve opening potted line by the anterior cone of spool, sealability is reliable; And the spool front end is provided with residue-removing rod, and material feeding port can in time obtain mediation, can not stop up.This valve is through improving, and is simple in structure, reliable in action.
Be described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
Fig. 2 is a spool direct through groove position right elevation.
As shown in Figure 1, new polyurethane bottler placer valve comprises valve body (2) and spool (1), in the valve body (2) valve body hole (6), valve body hole (6) is provided with material feeding port (9), material feeding mouth (7) and feedback outlet (8) from front to back successively, material feeding mouth (7) and material feeding port (9) and feedback outlet (8) communicate, it is characterized in that spool (1) and valve body hole (6) cooperate, and can in valve body hole (6), axially move; Be provided with a direct through groove (3) in the spool (1), Fig. 2 is this part right elevation, and material feeding mouth (7) communicates with feedback outlet (8) by direct through groove (3); Spool (1) front portion is provided with cone (4) and residue-removing rod (5), and cone (4) cooperates with potted line (10) in the valve opening, and residue-removing rod (5) cooperates with material feeding port (9).Material feeding port (9) links to each other with the mixing chamber of bottler placer.The other end of spool (1) stretches out outside the valve body, and is provided with pressure spring (11), and spool (1) is terminal to link to each other with lever (12), relies on cylinder (13) to open spool.
Its working procedure is as follows: when valve during to the mixing chamber material feeding, send into pressurized air to cylinder, piston is moved down, and make on the spool by lever and to move, spool has sealed the passage of material feeding mouth (7) with feedback outlet (8), and raw material enters mixing chamber from material feeding port (9).When valve stops to the mixing chamber material feeding, gas in the cylinder is bled off, pressure spring moves down spool, the anterior cone of spool (4) cooperates with potted line (10) in the valve opening, sealed the passage of material feeding mouth (7) and material feeding port (9), the stoste of material feeding mouth (7) flows into feedback outlet (8) by direct through groove (3); Simultaneously, the residue-removing rod of spool front end (5) cooperates with material feeding port (9), removes clout, prevents to stop up.
Claims (1)
