Abstract
The utility model discloses a two-position five-way high-precision plate-type throttling valve which comprises a valve body. A valve cavity is formed inside the valve body. Two air inlets matched with two working holes in a two-position five-way electromagnetic valve are formed in the front end face of the valve body. Two air outlets are formed in the rear end face of the valve body. The two side ends of the valve body are respectively and fixedly provided with a throttling valve base in an embedded mode. Adjusting rods which can transversely move are sleeved with the throttling valve bases. A sealing ring, a spring, an O-shaped ring, a locking nut and a valve rod cap are sequentially arranged on each adjusting rod in series from the inner end to the outer end. Conical slopes are arranged on the rod heads of the adjusting rods. Throttling grooves are formed in the conical slopes. The two-position five-way high-precision plate-type throttling valve is simple in structure, easy and convenient to assemble, capable of being directly installed on the two-position three-way electromagnetic valve, and capable of conducting high-precision adjustment on air pressure flow.
Description
Technical field
The utility model relates to pneumatic throttle technical field, especially relates to a kind of and two board-like throttle valve of highi degree of accuracy that five-way electromagnetic valve is used in conjunction with.
Background technique
Solenoid valve is Automatic Control Component conventional in control of industrialization system, and wherein the throttle valve for pneumatic control system is by changing throttling cross section, to control the pneumatic control components of air pressure flow.Throttle valve is conventionally used in conjunction with solenoid valve, is installed on the pipeline that source of the gas flows through, and installs and operation inconvenience all.And existing throttle-valve structure more complicated, assemble loaded down with trivial details, can not be for highi degree of accuracy air pressure Flow-rate adjustment.
Summary of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of two board-like throttle valve of five-way highi degree of accuracy, and it is simple in structure, assembles easyly, can directly be installed on two five-way electromagnetic valves, can carry out highi degree of accuracy adjusting to air pressure flow.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of two board-like throttle valve of five-way highi degree of accuracy, comprise that inside is provided with the valve body of valve pocket, valve body front-end face is provided with two inlet holes that match with two working holes of two five-way electromagnetic valves, valve rear end face is provided with two air outlet holes, the two side ends of valve body is fixedly embedded with respectively throttle valve seat, in throttle valve seat, be arranged with transversely movable adjustable lever, on adjustable lever, by inner end, go here and there and be provided with seal ring, spring, O shape circle, locking nut and valve thimble successively outward, the bar head of described adjustable lever is provided with tapered slope, in described tapered slope, offers throttling groove.
Wherein, on the inwall of described inlet hole, be arranged with packing ring.Described throttling groove is the groove in triangularity cross section.The edge of described throttling groove is provided with lead angle.
Wherein, described adjustable lever is provided with circular groove, and described O shape circle is arranged in described circular groove, and the two ends of described spring offset with described seal ring and described throttle valve seat respectively.Described adjustable lever and described throttle valve seat screw-thread fit, described adjustable lever and described locking nut screw-thread fit.
Adopt after technique scheme, the advantage that compared to the prior art the utility model had is:
Two board-like throttle valve of five-way highi degree of accuracy described in the utility model, adjustable lever is inserted in the valve pocket of valve body by throttle valve seat, on adjustable lever, by inner end, go here and there and be provided with seal ring, spring, O shape circle, locking nut and valve thimble successively outward, it is simple in structure, assemble easyly, save processing cost.When this two board-like throttle valve of five-way highi degree of accuracy are installed, the inlet hole of valve body front-end face is alignd with two working holes of two five-way electromagnetic valves, it is fixing that face and face are close to sealing, and pressurized air enters from inlet hole, and seal ring is close to valve pocket inner side under air pressure and spring action.Because the bar head of adjustable lever is provided with tapered slope, in described tapered slope, offer throttling groove, so transverse shifting adjustable lever can make throttling groove by the valve pocket conducting of seal ring both sides.When throttling groove integral body is positioned at the inner side of seal ring, the carrier frequency channel break between inlet hole and air outlet hole; When throttling groove a part or whole part is positioned at the outside of seal ring, passage conducting between inlet hole and air outlet hole, now by the position-adjustable throttling groove of transverse shifting adjustable lever, be positioned at the size of the throttling passage in seal ring outside, thereby realize, air pressure flow carried out to highi degree of accuracy adjusting.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1: sectional structure schematic diagram of the present utility model.
In figure, 1: valve thimble; 2: locking nut; 3: adjustable lever; 4: throttle valve seat; 5:O shape circle; 6: spring; 7: seal ring; 8: packing ring; 9: inlet hole; 10: valve body; 11: throttling groove; 12: air outlet hole.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, as shown in Figure 1.A kind of two board-like throttle valve of five-way highi degree of accuracy, comprise that inside is provided with the valve body 10 of valve pocket, valve body 10 front-end faces are provided with two inlet holes 9 that match with two working holes of two five-way electromagnetic valves, valve body 10 ear end faces are provided with two air outlet holes 12, the two side ends of valve body 10 is fixedly embedded with respectively throttle valve seat 4, in throttle valve seat 4, be arranged with transversely movable adjustable lever 3, on adjustable lever 3, by inner end, go here and there successively outward and be provided with seal ring 7, spring 6, O shape circle, locking nut 2 and valve thimble 1, it is simple in structure, assembles easy.The bar head of adjustable lever 3 is provided with tapered slope, offers throttling groove 11 in described tapered slope, can carry out highi degree of accuracy adjusting to air pressure flow.
On the inwall of inlet hole 9, be arranged with packing ring 8, when these two board-like throttle valve of five-way highi degree of accuracy and two five-way electromagnetic valves are used in conjunction with, packing ring 8 plays the effect being tightly connected.Throttling groove 11 is the groove in triangularity cross section, and throttling groove 11 degrees of regulation of this shape are higher.The edge of throttling groove 11 is provided with lead angle, when preventing adjustable lever 3 transverse shiftings or rotating by seal ring 7 scratches.
