Abstract

The invention relates to a valve, in particular to a valve for releasing the glass glue and foaming glue from pressure pot, which comprises a valve body and a valve element, wherein, the valve element comprises a post and end faces; the post is in the outlet channel of valve body and moves up and down; the end faces are engaged with the lower end face of outlet channel; the post is hollow axially; the bottom of post has through hole at the side wall; the upper end face of outlet channel is arranged with a rubber muffle; the upper end of the post protruded outside the outlet channel is inserted into the rubber muffle. The invention has simple structure, better sealing, and repeated application, while the elements are engaged compacted.

Description

Valve

Technical field

The present invention relates to a kind of valve, specifically relate to a kind of valve that silicon sealant, foamed glue etc. is discharged usefulness from pressurized tank.

Background technique

Existing this valve seal performance is good inadequately, does not use up if one bottle of glue is disposable, do not put several days colloids just again spray do not come out very waste.

Summary of the invention

Therefore, the object of the present invention is to provide a kind of durable in use, valve that sealability is good.

The object of the present invention is achieved like this:

A kind of valve, comprise valve body and spool, spool comprises cylinder and end face, cylinder is located in the valve outlet passage and can moves up and down within it, end face cooperates with the lower end surface of outlet passage, described cylinder axis is to hollow, cylinder bottom sidewall is provided with through hole, the upper-end surface of described outlet passage is provided with rubber bush, stretch out the cylinder upper end portion of outlet passage and intert in rubber bush, cylinder outer wall and the outlet passage inwall stayed in the outlet passage closely cooperate, and it is characterized in that: the Lower Half inwall of described cylinder outer wall and rubber bush closely cooperates, it is big that the first half inner diameter of rubber bush becomes, the bottom of rubber bush and valve body engagement.

Above-mentioned purpose also can be further perfect by following technical proposals:

Described rubber bush top is provided with packing ring, the cycle surface of packing ring is pressed on the rubber bush end face, the inner ring end face of packing ring freely is pressed on the cylinder end face or the inner ring end face and the cylinder end face of packing ring weld, and the axial hollow of the axial hollow of packing ring and cylinder connects.

Described rubber bush bottom outer wall is shaping one circle step outwards, has a gland to be set on the rubber bush outer wall, and the inner ring mouth of gland is pressed on the ledge surface, and the outer ring port of gland is pressed in the valve body.

Structural design advantages of simple of the present invention, good seal performance, bottle arranging glue can use repeatedly, does not have waste, cooperates compactness firmly between each component, can bear various collisions, and it is also convenient to install.

Description of drawings

Structural representation when Fig. 1 seals for present embodiment;

Fig. 2 is the axial decomposing schematic representation of Fig. 1.

Embodiment

The invention will be further described below in conjunction with drawings and Examples.

Embodiment, in conjunction with Fig. 1 and Fig. 2, a kind of valve, comprise valve body 1, spool 2, Returnning spring 3, buckle 4 and iron ring 5, iron ring 5 is installed in valve body 1 top, and Returnning spring 3 one ends withstand on spool 2 bottom surfaces, Returnning spring 3 the other end are pressed in buckle 4 surfaces, and buckle 4 is engaged on valve body 1 bottom.

Spool 2 comprises axially hollow cylinder 2-1 and end face 2-2, cylinder 2-1 is located in valve body 1 outlet passage 7 and can moves up and down within it, and cylinder 2-1 outer wall and outlet passage 7 inwalls closely cooperate, cylinder 2-1 bottom sidewall is provided with through hole 8, end face 2-2 cooperates with the lower end surface of outlet passage 7, the upper-end surface of outlet passage 7 is provided with rubber bush 9, and the bottom of rubber bush 9 and valve body 1 engagement are stretched out the cylinder 2-1 upper end portion of outlet passage 7 and interted in rubber bush 9.The Lower Half inwall of cylinder 2-1 outer wall and rubber bush 9 closely cooperates, and it is big that the first half inner diameter of rubber bush 9 becomes, and internal diameter becomes most rubber sleeve barrel and is deformed into the lantern shape when rubber bush 9 pressurizeds.Rubber bush pushes up 9 tops and is provided with packing ring 10, the cycle surface of packing ring 10 is pressed on rubber bush 9 end faces, the inner ring end face of packing ring 10 freely is pressed in the inner ring end face and the welding of cylinder 2-1 end face of cylinder 2-1 end face or packing ring 10, and the axial hollow of the axial hollow of packing ring 10 and cylinder 2-1 connects.Rubber bush 9 bottom outer walls are shaping one circle step 11 outwards, has a gland 12 to be set on rubber bush 9 outer walls, and the inner ring mouth of gland 12 is pressed on step 11 surfaces, and the outer ring port of gland 12 is pressed in the valve body 1.

During use, packing ring 10 pressurizeds, the distortion of rubber bush 9 first halves, the inner ring end face of packing ring is compression leg body 2-1 down, and end face 2-2 is toward moving down Returnning spring 3 pressurizeds, through hole 8 on the cylinder 2-1 sidewall communicates with body cavity, and gas via through holes 8 enters cylinder intracavity, enters spray gun through pad Figure 10 again.

Claims
