Abstract
The utility model relates to an air exhaust one -way valve, including valve body, case, spring, cap nut and gum cover, the one end of valve body is provided with the entrance, is provided with the exhaust passage in the entrance, and the other end of valve body is provided with the external screw thread, and cap nut and valve body threaded connection are formed with the cavity between cap nut and the valve body, be provided with the exhaust hole on the lateral wall of cavity, the case is installed at the cavity inside seal or is opened the exhaust passage, the spring sets up between cap nut and case, the gum cover sets up in the hole department of exhausting. The utility model discloses simple structure can control the cooperation of formula solenoid valve with gas, realizes gaseous discharge, the exhaust hole department of check valve sets up gum cover protection, has realized reliable waterproof dustproofly, has prevented in moisture and unnecessary thing get into the coil pack through the exhaust hole, guarantees the product operational reliability.
Description
Technical field
The utility model relates to a kind of one-way valve structures.
Background technology
Gas control type magnetic valve need to drive valve core movement by gas load, in the time of valve closing,Manipulation gas reliably need to be discharged; Meanwhile, for reliable water proof and dust proof, moisture and fifth wheel have been stopedEnter by steam vent in the coil block of magnetic valve, ensure product work reliability; In addition, require systemSystem compact conformation, volume is little. Existing check valve is difficult to meet simple in structure, accurate exhaust and waterproof simultaneouslyDustproof needs.
Summary of the invention
In order to solve the reliable discharge of the magnetic valve controlled gas of gas control type, meet water proof and dust proof simultaneouslyNeed, the utility model provides a kind of exhaust check valve.
Technical solution of the present utility model is:
The exhaust check valve that the utility model provides, comprises valve body 25 spools 24 and spring 23, and it is specialPart is, described exhaust check valve also comprises cap nut 21 and gum cover 22,
One end of described valve body 25 is provided with entrance, in described entrance, is provided with exhaust passage, described inThe other end of valve body 25 is provided with external screw thread, and described cap nut 21 is threaded with valve body 25, described inBetween cap nut 21 and valve body 25, be formed with cavity, on the sidewall of described cavity, be provided with steam vent 27;
Described spool 24 is arranged on the interior sealing of cavity or opens exhaust passage;
Described spring 23 is arranged between cap nut 21 and spool 24;
Described gum cover 22 is arranged on steam vent 27 places.
Further, between above-mentioned spool 24 and valve body 25, be ball face sealing.
Further, above-mentioned cap nut 21 is provided with spring fitting groove, and described spring 23 is positioned at springIn mounting groove.
Compared with prior art, advantage is the utility model:
1, the utility model is simple in structure, can coordinate with gas control type magnetic valve, realizes the row of gasGo out; The steam vent place of check valve arranges gum cover protection, has realized reliable water proof and dust proof, has stoped waterPoint and fifth wheel enter in coil block by steam vent, ensure product work reliability.
2, the utility model is installed simply, and cap nut is connected with valve body screw thread, and spool and spring fitting existIn housing between cap nut and valve body.
3, ball face sealing between the utility model spool and valve body, between spool and valve body, frictional force is little, valveCore is opened constant pressure, realizes the accurate exhaust of exhaust gas passage.
4, in cap nut of the present utility model, spring fitting groove is set, makes check valve overall structure tightGather, volume is little, lightweight and motion is reliable.
Brief description of the drawings
Fig. 1 is the structure chart of the utility model check valve.
Wherein Reference numeral is: 21-cap nut, 22-gum cover, 23-spring, 24-spool, 25-valve body,26-entrance, 27-steam vent.
Detailed description of the invention
As shown in Figure 1, exhaust check valve of the present utility model, comprise valve body 25, spool 24, spring 23,Cap nut 21 and gum cover 22, one end of valve body 25 is provided with entrance, is provided with exhaust in entrancePassage, the other end of valve body 25 is provided with external screw thread, and cap nut 21 is threaded with valve body 25, outerBetween cover nut and valve body, be formed with cavity, on the sidewall of described cavity, be provided with steam vent 27, spool 24Be arranged on the interior sealing of cavity or open exhaust passage; Spring 23 be arranged on cap nut 21 and spool 24 itBetween; Gum cover is arranged on steam vent place, ball face sealing between spool 24 and valve body 25. Cap nut 21 is establishedBe equipped with spring fitting groove, spring 23 is positioned at spring fitting groove.
When exhaust, medium that check valve entrance 26 pressure produce is made every effort to overcome and is taken that one-way valve spring 23 producesSpring force, inner elements of check valve 24 is opened, and gas is discharged; When check valve entrance 26 is during without pressure medium,Inner elements of check valve 24 is again closed under the spring-force driven dual of one-way valve spring 23.
