Description
[technical field]
The utility model relates to the technical field of the technical field of chiller plant, particularly one-way valve.
[background technique]
In chiller plant, one-way valve is important parts, it to compressor safe and stable operation play a very important role, steel ball type one-way valve a kind of uses one-way valve more widely.Due to the characteristic of chiller plant, need one-way valve to have good sealing, this just requires that steel ball well can play seal action when closed check valve state, and existing steel ball type one-way valve sealing is not enough, have impact on the normal operation of equipment.Existing minor diameter steel ball type one-way valve can not export large discharge simultaneously, and improve flow can only make major diameter by steel ball type one-way valve, also improves the requirement of installing space while waste material.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, and propose a kind of large discharge steel ball type one-way valve, can have good sealing under can making one-way valve in off position, the one-way valve of minor diameter also can export large discharge.
For achieving the above object, the utility model proposes a kind of large discharge steel ball type one-way valve, comprise valve body, valve seat, fixing frame, steel ball, seal ring, described valve body left end has import, valve body right-hand member has outlet, described valve seat is in valve body, valve seat axis there is through hole, through hole is horizontal hourglass-shaped, seal ring is had in through hole, described seal ring outer wall is close to through-hole wall, seal ring inner hollow, seal ring hollow space is horizontal hourglass-shaped, described valve seat left end has filtering screen, valve seat right-hand member has fixing frame, fixing frame low order end has at the bottom of frame, steel ball is had in fixing frame, steel ball right-hand member is connected with spring, spring is connected with Kuang Di center, described fixing frame sidewall there are some openings.
As preferably, on the same axis, fixing frame internal diameter is identical with seal ring low order end internal diameter for described fixing frame and valve seat.
As preferably, described steel ball size is less than seal ring maximum inner diameter, is greater than seal ring minimum diameter.
As preferably, described opening is strip, and on fixed outer frame sidewall, opening area occupied accounts for 1/3 ~ 3/4 of the fixed outer frame sidewall gross area.
The beneficial effects of the utility model: the utility model, by being arranged on fixing frame by large-area opening, has not only saved material, also can ensure the smoothness that refrigeration agent circulates, and make minor diameter one-way valve also can have large discharge; Seal ring hollow space is made in horizontal hourglass-shaped, and steel ball right-hand member arranges spring, make one-way valve descend in off position steel ball under elastic force effect with seal ring inwall close contact, have good sealing; Through hole on valve seat is horizontal hourglass-shaped, and under making one-way valve in off position, seal ring and through-hole wall close contact, improve sealing, can prevent seal ring from sliding in through hole when opening state; Filtering screen can filter the impurity in refrigeration agent, reduces impurity to the destruction of sealing.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the plan view of a kind of large discharge steel ball type of the utility model one-way valve;
Fig. 2 is the fixing frame erectility plan view of a kind of large discharge steel ball type of the utility model one-way valve.
In figure: at the bottom of 1-valve body, 2-valve seat, 3-fixing frame, 4-seal ring, 5-steel ball, 11-import, 12-outlet, 21-through hole, 22-filtering screen, 31-frame, 32-opening, 53-spring.
[embodiment]
Consult Fig. 1 and Fig. 2, a kind of large discharge steel ball type of the utility model one-way valve, comprise valve body 1, valve seat 2, fixing frame 3, steel ball 5, seal ring 4, described valve body 1 left end has import 11, valve body 1 right-hand member has outlet 12, described valve seat 2 is in valve body 1, valve seat 2 axis there is through hole 21, through hole 21 is in horizontal hourglass-shaped, seal ring 4 is had in through hole 21, described seal ring 4 outer wall is close to through hole 21 inwall, seal ring 4 inner hollow, seal ring 4 hollow space is horizontal hourglass-shaped, described valve seat 2 left end has filtering screen 22, valve seat 2 right-hand member has fixing frame 3, fixing frame 3 low order end to have at the bottom of frame 31, steel ball 5 is had in fixing frame 3, steel ball 5 right-hand member is connected with spring 53, spring 53 is connected with Kuang Di 31 center, described fixing frame 3 sidewall there are some openings 32, described fixing frame 3 and valve seat 2 are on the same axis, fixing frame 3 internal diameter is identical with seal ring 4 low order end internal diameter, described steel ball 5 diameter is less than seal ring 4 maximum inner diameter, be greater than seal ring 4 minimum diameter, described opening 32 is in strip, on fixing frame 3 outer side wall, opening 32 area occupied accounts for 1/2 of the fixing frame 3 outer side wall gross area.
Utility model works process:
In the course of the work, refrigeration agent enters from import 11 a kind of large discharge steel ball type of the utility model one-way valve, through the filtration of filtering screen 22, pushes steel ball 4 open, and refrigeration agent, by opening 32, finally leaves from outlet 12.Opening 32 is arranged on fixing frame 3, has not only saved material, also can ensure the smoothness that refrigeration agent circulates, and makes minor diameter one-way valve also can have large discharge; Seal ring 4 hollow space is made in horizontal hourglass-shaped, and steel ball 5 right-hand member arranges spring 53, make one-way valve descend in off position steel ball 5 under elastic force effect with seal ring 4 inwall close contact, have good sealing; Through hole on valve seat 2 21 is in horizontal hourglass-shaped, and under making one-way valve in off position, seal ring 4 and through hole 21 inwall close contact, improve sealing, can prevent seal ring 4 from sliding in through hole 21 when opening state; Filtering screen 22 can filter the impurity in refrigeration agent, reduces impurity to the destruction of sealing.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
