Abstract
The utility model provides a two-position four-way rotary piston type gas flow direction control valve, which is mainly composed of a valve body 8 and a valve core 7, wherein an inner cavity of the valve body 8 forms a cone shape; the valve body 8 comprises four gas channels connected with the inner cavity; the valve core 7 is a cone structure; the upper part and the lower part of the valve core 7 is provided with a cone surface, and the middle part is provided with a partition board structure; the valve core 7 is inserted into the valve body 8. The utility model is characterized in that the lower part of the valve core 7 is provided with a gap regulation device which mainly screws in a regulation bolt 10 arranged in a lower cover board 9 of the valve body 8; the external end of the regulation bolt 10 is provided with a locking nut 11; the gap regulation device is used for regulating the sealing match gap of the valve body 8 and the valve core 7. The two-direction four-way rotary piston type gas direction control valve provided by the utility model has the advantages that the valve body 8 and the valve core 7 adopt a cone surface form and are matched with the gap regulation device, so the sealing performance is good, the direction commutation is rapidly, the structure is simple and the gas flowing direction can be conveniently controlled.
Description
Technical field
The utility model relates to the gas direction control gear, specifically, and two-position four-way cock-type gas direction control valve.
Background technique
At present the gas direction control gear is divided into two kinds of slide block type and cock-types by valve core structure, slide block type is relatively more responsive to the impurity in the source of the gas medium, easily cause sealing wear, tight contact guarantees sealing and the cock-type structure is by the conical surface, particularly relatively large control valve is because the spool quality is big, easily kill, rotate difficulty.
Summary of the invention
The gas direction control valve that the purpose of this utility model is to provide a kind of and commutates conveniently, resistance is little, seal clearance is adjustable.
The utility model provides a kind of two-position four-way cock-type gas direction control valve, mainly constitute by valve body 8 and spool 7, the inner chamber of valve body 8 is conical, and four gas channels that link to each other with inner chamber are arranged, and spool 7 is a conical structure, leave the conical surface (round platform) up and down, the centre is a diaphragm structure, and spool 7 inserts in the valve body 8, and it is characterized in that: spool 7 belows are provided with lash adjusting device, mainly be the adjustment bolt 10 that screws in 9 li of valve body 8 lower cover plates, locking nut 11 arranged in adjustment bolt 10 outer ends.Lash adjusting device is used to adjust the gap that is sealed and matched of valve body 8 and spool 7.
The two-position four-way cock-type gas direction control valve that the utility model provides, its valve body 8 tops can be provided with drive unit 1, and drive unit 1 links to each other with poppet shaft 14 by coupling shaft 2, and poppet shaft 14 links to each other with spool 7 by key 15.Drive unit 1 can be a form such as mechanical, hydraulic pressure, pneumatic.
The two-position four-way cock-type gas direction control valve that the utility model provides, its coupling shaft 2 can link to each other with poppet shaft 14 by connecting sleeve 17, on coupling shaft 2 or connecting sleeve 17, can be provided with limit stoper, this limit stoper is to be made of flange plate 3 and the limit switch 4 that is fixed on valve body 8 link press spans 18, with the commutation position of control spool 7.
The two-position four-way cock-type gas direction control valve that the utility model provides, its spool 7 tops can be spacing with upper cover plate 13 and spring 5.
The two-position four-way cock-type gas direction control valve that the utility model provides, its poppet shaft 14 two ends can be provided with bearing 6 and 12, to alleviate the resistance of spool 7.
The advantage of the two-position four-way cock-type gas direction control valve that the utility model provides is: valve body, spool conical surface seal form, be equipped with lash adjusting device, and have good airproof performance, commutation is rapidly, and is simple in structure, easily the control gaseous flow direction.
Description of drawings

Embodiment
A kind of two-position four-way cock-type gas direction control valve, its structure mainly is made of parts such as drive unit 1, link press span 18, coupling shaft 2, connecting sleeve 17, limit switch 4, flange plate 3, valve body 8, spool 7, lash adjusting device, bearing 6 and 12 as shown in Figure 1.Described drive unit 1 is machinery, spinning or pneumatic form, for the rotation of spool 7 provides power.
Spool 7 is a conical structure, and the middle part symmetry hollows out, and round platform is left in spool 7 tops, bottom, and diaphragm structure is left in the centre.Spool 7 centers are porose, are convenient to mandrel and connect.Spool 7 is installed in the empty body of valve body 8 tapers.
Lash adjusting device mainly is made up of adjustment bolt 10, locking nut 11, bearing 12, is used to adjust the matching gap of spool 7 and valve body 8 cavitys.Adjusting bolt 10 is installed on the lower cover plate 9 with internal thread.
The direction of body that this model utility is ventilated is that valve body 8 adjacent two vents communicate.Proper functioning has two ventilation positions.
When drive unit 1 drives coupling shaft 2 rotations, spool 7 rotations, when spool 7 rotated to 4 of limit switches, drive unit 1 stopped the rotation, this moment spool about in the of 7 the conical surface all the time mutually closely connected with valve body 8 conical surfaces, gas does not have external leakage.The spool 7 partition part two ends and valve body 8 conical surfaces are closely connected, and valve body 8 adjacent two gas channel A are communicated (as shown in Figure 2) with D with B and C.Valve body 8 two other adjacent gas channel A link to each other with B with C with D when spool 7 rotates to another limit switch 4, change airflow direction.
