Description
Technical field
The utility model is a kind of multi-functional check-valves, belongs to Engineering Control technical field.
Background technology
At present in water pump water supply system and pipeline irreversibly deliver, check-valves has become indispensable pipeline control element,
Particularly in frequent unidirectional Pipeline transport, the quality of a check-valves becomes the pass of entire transport system trouble-free operation
Key, still, check-valves now on the market is almost similar, and function is more single when in use；Particularly supply water in water pump
In system, due to being stopped suddenly for water pump, check-valves both ends is caused to generate very big pressure differential, generate very strong current punching
Power is hit, check-valves inner control member is so easily destroyed, check-valves is caused to damage, and with very big pipeline noise, right
When check-valves carries out periodic maintenance, it need to integrally dismantle, check its unidirectionally controlled function, it is time-consuming and laborious.
Utility model content
In view of the deficienciess of the prior art, the utility model aim is to provide a kind of multi-functional check-valves, to solve
The problems mentioned above in the background art, the utility model is designed reasonably, practicability is high, is suitble to promote.
To achieve these goals, the utility model is to realize by the following technical solutions：Including fixed cover, gate
Combination, valve body, attachment screw, cushion collar and observation bolt, the fixed cover are mounted on the top of valve body, the gate combination peace
Between valve body and fixed cover, the cushion collar be mounted on valve body one side, the valve body be equipped with water inlet, water outlet,
Valve chamber, valve seat and taper thread hole, the gate combination include spring, valve-rod combination and seal head, and the spring is mounted on valve rod
The one side of combination, the seal head are mounted on the opposite side of valve-rod combination, and the observation bolt is mounted on the taper thread on valve body
In hole.
As a kind of preferred embodiment of the utility model, the cushion collar is mounted on going out for valve body by attachment screw
In the mouth of a river, the fixed cover is mounted on by bolt on valve body.
As a kind of preferred embodiment of the utility model, sealing ring is equipped between the fixed cover and valve body, it is described
Cushion collar is equipped with cushion hole.
The beneficial effects of the utility model：A kind of multi-functional check-valves of the utility model, including fixed cover, valve body,
Attachment screw, cushion collar, observation bolt, spring, valve seat, valve-rod combination and seal head.
1. during pipeline water delivery, when check-valves both ends generate pressure differential suddenly, closure of check ring, water is stood in pipeline
I.e. very strong reverse impact power by the cushion hole of the cushion collar side of shut-off valve water outlet, reduces the impact force of current, so as to
It reduces the pipeline noise that impact is brought and alleviates the destruction to check-valves inner control member；
2. when that need to be safeguarded to check-valves, the observation bolt of body base is opened using spanner, it can using headlamp
It is convenient and efficient to observe whether check-valves is reversely revealed；
3. the multi-functional check valve design is reasonable, practicability is high, is suitble to promote.

Specific embodiment
Technical means, creative features, achievable purpose and effectiveness to realize the utility model are easy to understand, below
With reference to specific embodiment, the utility model is expanded on further.
It please refers to Fig.1 to Fig. 6, the utility model provides a kind of technical solution：A kind of multi-functional check-valves, including fixation
Lid 1, gate combination 2, valve body 3, attachment screw 4, cushion collar 5 and observation bolt 6, the fixed cover 1 are mounted on the top of valve body 3
Portion, the gate combination 2 are mounted between valve body 3 and fixed cover 1, and the cushion collar 5 is mounted on the one side of valve body 3, the valve
Body 3 is equipped with water inlet, water outlet, valve chamber, valve seat 9 and taper thread hole 10, and the gate combination 2 includes spring 11, valve rod group
12 and seal head 13 are closed, the spring 11 is mounted on the one side of valve-rod combination 12, and the seal head 13 is mounted on valve-rod combination 12
Opposite side, it is described observation bolt 6 be mounted on valve body 3 on taper thread hole 10 in.
As a kind of preferred embodiment of the utility model, the cushion collar 5 is mounted on valve body 3 by attachment screw 4
Water outlet in, the fixed cover 1 by bolt 8 be mounted on valve body 3 on.
As a kind of preferred embodiment of the utility model, sealing ring 7, institute are equipped between the fixed cover 1 and valve body 3
Cushion collar 5 is stated equipped with cushion hole.
When in use, check-valves being linked into the pipeline for needing one-way transmission, check-valves is closure state under normality, such as
When starting to convey water, current are entered by the water inlet of valve body 3, under the action of hydraulic pressure so that the spring 11 in gate combination 2
It shrinks, valve-rod combination 12 is moved in the guide groove of fixed cover, and seal head 13 is separated with the valve seat 9 of valve body 3, and check-valves is opened, water
Stream is discharged by the hole among cushion collar 5 into valve body cavity, realizes that check-valves opens transmission, when source is sudden shut off, in valve body
Water inlet hydraulic pressure rapid drawdown, closure of check ring generates very big moment reverse impact power, pipe in check-valves water outlet lateral line
Water in road flows back rapidly, and the current for having very strong impact force enter cushion collar 5 in valve body 3, by the cushion hole of side wall, current punching
Hitting power will weaken significantly, and then reduce the destruction due to the noise of water hammering generation and to check-valves internal component,
If occurring efficiency of transmission reduction in use, the observation bolt 6 of 3 bottom of valve body is opened using spanner, passes through taper thread
Hole 10 is irradiated 9 periphery of valve seat, has seen whether leak case, has more efficiently pinpointed the problems.The multi-functional non-return
Valve design is reasonable, and practicability is high, is suitble to promote.
