Description

Valve group

Technical field

The utility model relates to spraying machine fields, and in particular to valve group.

Background technique

In the production process of spraying machine, valve group typically serves to more important role, but uses actual Cheng Zhong leads to the sealing of valve group since when the fixed effect to spring is poor leads to prolonged use, spring is easy displacement Effect is deteriorated, and the problem of variation so as to cause spray effect, while traditional valve group needs biggish pressure that could arrive Water flow is allowed to pass through up to opening state, use is more laborious, while the spraying machine of different model needs different valve groups, therefore The valve group that different preparation different models is needed in production process, causes the applicability of valve group low.

Utility model content

In view of the deficienciess of the prior art, and a kind of use good the purpose of this utility model is to provide sealing effect saves The valve group of power.

To achieve the above object, the utility model provides following technical solution: including valve cover and valve cover plug, valve Cover is equipped with sealing device, and cavity is equipped in valve cover, and the mounting hole for installing valve cover plug, installation are additionally provided on valve cover Hole is connected with cavity, several apopores are additionally provided on valve cover, and valve cover is equipped with fixed part beyond the Great Wall, is equipped in fixed part solid Determine cavity；

Spring and valve plug are equipped in cavity, spring one end is located in fixed cavity, and the other end and valve plug are contradicted and connected, Valve is equipped with the fixed lobe for fixed spring beyond the Great Wall；

Sealing device includes valve lid and valve lantern ring, and valve lid and valve plug are inconsistent, and valve, which covers, is additionally provided with pressurization Hole.

Further, valve is additionally provided with dashpot beyond the Great Wall.

Further, valve lantern ring is equipped with the first limiting slot and the second limiting slot, and the first limiting slot and valve lid match.

Further, the annular array right side is gone back on valve lantern ring has several fixed blocks.

The deficiencies in the prior art are compared, the utility model has the advantages that when in use brought by technical solution provided by the utility model, Both ends of the spring is fixed portion respectively and valve plug is fixed, therefore even if spring will not be displaced under prolonged use, The problem of spray effect is deteriorated caused by being displaced because of spring is avoided, while the presence of fixed part is but also living Men Sai collides in the case where pressure is excessive with fixed part, avoids living caused by valve plug collides with valve cover The problem of door cover damages, while the presence of fixed part allows to limit the flow that water flow passes through in the unit time, avoids In unit time by the water flow excessive damage caused to other component the problem of generation, while passing through replacement valve Cover plug is it is also possible that valve group adapts to the spraying machine of different size, so that the applicability of valve group is stronger, saving is produced into This, pressurized hole includes big aperture and microstome, is connected between big aperture and microstome by arcwall, therefore when hydraulic pressure is smaller When, by the presence of pressurized hole, so that the pressure at valve plug increases, so that valve plug is in the open state, avoid spraying The problem of machine can not work because water flow pressure is smaller.

Specific embodiment

It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent It selects embodiment to be merely to illustrate and explain the present invention, is not used to limit the utility model.

- Fig. 4 is described further the utility model referring to Fig.1.

Valve group, including valve cover 1 and valve cover plug 2, valve cover 1 are equipped with sealing device, are equipped with sky in valve cover 1 Chamber is additionally provided with the mounting hole 12 for installing valve cover plug 2 on valve cover 1, and mounting hole 12 is connected with cavity, on valve cover 1 Several apopores 11 are additionally provided with, valve cover plug 2 is equipped with fixed part 21, fixed cavity is equipped in fixed part 21；

Spring 4 and valve plug 3 are equipped in cavity, 4 one end of spring is located in fixed cavity, and the other end and valve plug 3 contradict Connection, valve plug 3 are equipped with the fixed lobe 31 for fixed spring 4；

Sealing device includes valve lid 5 and valve lantern ring 6, and valve lid 5 and valve plug 3 are inconsistent, is additionally provided on valve lid 5 Pressurized hole；When in use, 4 both ends of spring are fixed portion 21 respectively and valve plug 3 is fixed, therefore even if prolonged use Under, spring 4 will not be displaced, and avoiding causes sealing effect to be deteriorated because spring 4 is displaced to influence by spraying The problem of effect, occurs, while the presence of fixed part 21 is but also valve plug 3 in the case where pressure is excessive, is sent out with fixed part 21 Raw collision avoids the problem of valve cover 1 caused by valve plug 3 collides with valve cover 1 damages, while fixed part 21 Presence allow to limit the flow that water flow passes through in the unit time, avoid in the unit time by water flow it is excessive The problem of causing the damage to other component generation, while by replacement valve cover plug 2 it is also possible that valve group adapts to not The spraying machine of same specification saves production cost, pressurized hole includes big aperture 51 and microstome so that the applicability of valve group is stronger 52, it is connected between big aperture 51 and microstome 52 by arcwall 53, therefore when hydraulic pressure is smaller, pass through depositing for pressurized hole So that the pressure at valve plug 3 increases so that valve plug 3 is in the open state, avoid spraying machine because water flow pressure compared with It is small and the problem of can not work.

Further, dashpot 32 is additionally provided on valve plug 3；When water flow pressure is larger, the presence of dashpot 32 makes portion Point water flow turns to, and the buffer function to water flow is played, between valve plug 3 caused by avoiding hydraulic pressure larger and valve plug cover 2 Extruding force increase leads to the problem of being prone to wear.

Further, valve lantern ring 6 is equipped with the first limiting slot 61 and the second limiting slot 62, the first limiting slot 61 and valve lid 5 match, and the second limiting slot 62 and valve cover 1 match, therefore when in use, and valve lid 5 and valve cover 1 are by valve lantern ring 6 is fixed, therefore valve cover 1 and valve lid 5 will not move, so that sealing effect is more preferable.

Further, the annular array right side is gone back on valve lantern ring 6 has several fixed blocks 63, and fixed block 63 connects with valve lid 5 Touching, therefore when operating, water flow can enter in the cavity that adjacent fixed block 63 is formed, therefore play preferable sealing function, Simultaneously because the presence of hydraulic pressure makes the fixed effect to valve lid more preferable, valve lid is not easily shifted, so that sealing effect is more preferable.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model It protects in range.
