Abstract
The utility model discloses a novel hand-pulled valve, which comprises a valve body, a rear cover and a front cover, wherein the valve body is provided with an intake hole, an exhaust hole, a working air hole and a valve rod chamber, a valve rod is mounted in the valve rod chamber in a clearance fit manner, and is provided with an O-shaped ring, a C-shaped ring and an exhaust ring, a manual rod with an O-shaped sealing ring is connected with the valve rod through a connector, a retainer is fixed between the valve body and the front cover, a retaining ring, a left limiting sleeve and a right limiting sleeve are fixed in an open chamber of the retainer, the left and the right limiting sleeves are positioned at both sides of the retaining ring, and two juxtaposed positioning sleeves are fixed on the valve rod, and are provided with annular slots matched with the positioning rings. Compared with the conventional hand-pulled valve, the hand-pulled valve has the advantages of simple structure, stable reversing, little impact, low noise and high adaptability, and can normally operate under the temperature of 40 DEG C below zero, and moreover, the handle is good during operation.
Description
Technical field:
The utility model belongs to the pneumatic valve technical field, relates to a kind of hand valve more specifically.
Background technique:
Pulling air valve is a kind of of manual air valve, it does not need electromagnetic gas valve to need electric energy to promote like that, be fit to much fields of needs hand switch, for example bus door closes or the like, that but existing manual air valve impacts in commutation process is very big, noise is very high, and in operating process, not having feel, the action during pulling is not steady, action is very big.
The model utility content:
The purpose of this utility model is at the deficiencies in the prior art part, provides that a kind of reversing impact is little, noise is low, the hand valve of feel is arranged in the operating process.
Technology solution of the present utility model is as follows:
Novel hand valve, comprise valve body, bonnet and protecgulum, form inlet hole on the described valve body, exhaust port, work pore and valve-rod cavity, described valve-rod cavity internal clearance cooperation is equipped with a valve rod, on valve rod, be provided with O shape circle, c shape circle and exhaust ring, the manual rod that has o shape seal ring is connected with described valve rod by a connection set, fix a positioning seat between valve body and the protecgulum, atrium internal fixation at positioning seat has positioning ring and the left and right sides stop collar that is positioned at the positioning ring both sides, be fixed with two setting sleeves arranged side by side on the valve rod, form the annular slot that matches with described positioning ring on the described setting sleeve.
Described novel hand valve, described connection set are that a diameter is that 1.8 millimeters, length are 11 millimeters straight pin.
Described novel hand valve also has a gas control mouth on the described bonnet, described gas control mouth communicates with valve-rod cavity at bonnet and the fixing back of valve body.
Described novel hand valve, described bonnet with the contacted surface of valve body on once a cushion pad and an O-ring seals are installed.
Described novel hand valve is bolted and fixed with one handle on the described manual rod.
The utility model beneficial effect is:
The utility model is compared with the existing valve that manually draws, and is not only simple in structure, and commutation is steady, impact is little, noise is low, and adaptability is strong, can work normally under subzero 40 degrees centigrade temperature, and in operation feel be arranged very.Especially utilize setting sleeve that valve rod is positioned, make valve rod more stable in operation.This novel hand valve also has a gas control mouth in addition, can control the switching of hand valve by pressurized gas through this gas control mouth, manually increasing a kind of controlling method again outside the control, can when inconvenience is manual, utilize the gas control mouth to control the closure of hand valve, strengthen this novel application area and market competitiveness greatly.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment, see shown in the accompanying drawing 1: novel hand valve, comprise valve body 1, bonnet 2 and protecgulum 3, form inlet hole 101 on the described valve body 1, exhaust port 102, work pore 103 and valve-rod cavity 104, three pores and valve-rod cavity 104 all communicate, and it is vertical with valve-rod cavity 104, described valve-rod cavity 104 internal clearances cooperation is equipped with a valve rod 4, standard one valve rod 4 in gap can rotate freely in valve-rod cavity 104 and be as the criterion, can adopt NBS also can adopt industry standard, can not be excessive and leak gas in the gap in a word, catching phenomenon appears when can not too smallly make valve rod 4 rotate in valve-rod cavity 104 again, on valve rod 4, be provided with O shape circle 5, c shape circle 6 and exhaust ring 7, the manual rod 9 that has o shape seal ring 8 is connected with described valve rod 4 by a connection set, fix a positioning seat 10 between valve body 1 and the protecgulum 3, valve body 1 and protecgulum 3 link together by screw, and positioning seat 10 is just passed and fixes by this screw, atrium 1001 internal fixation at positioning seat 10 have positioning ring 11 and the left and right sides stop collar 12 that is positioned at positioning ring 11 both sides, 13, positioning ring 11 and left and right sides stop collar 12,13 all are placed in the atrium 1001 with state freely, be fixed with two setting sleeves arranged side by side 14 on the valve rod 4, form the annular slot 1401 that matches with described positioning ring 11 on the described setting sleeve 14, by this annular slot 1401, make the inside caliper of positioning ring 11 connect within it.
Described connection set is that a diameter is that 1.8 millimeters, length are 11 millimeters straight pin 15, make valve rod 4 and manual rod 9 demountable linking together by this straight pin 15, and straight pin is located in the valve rod 4 of exhaust ring 7 inside.
Also have a gas control mouth 301 on described bonnet 2, described gas control mouth 301 communicates with valve-rod cavity 104 at bonnet 2 and valve body 1 fixing back.By this gas control mouth, can be not by manually just controlling the on-off action of this novel hand valve, making has increased a kind of control function again on pure manual basis, more be convenient to user's control and operation.
Described bonnet 2 with valve body 1 contacted surface on once cushion pad 16 and one 0 shape seal rings 17 are installed.
