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.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of steel ball type one-way valve, has good sealing when can make one-way valve in off position, and structure is simple simultaneously, saves material, reduces costs.
For achieving the above object, the utility model proposes a kind of steel ball type one-way valve, comprise valve body, valve seat, fixing frame, end cap, import is had on the left of described valve body, outlet is had on the right side of valve body, described valve seat is in valve body, valve seat axis there is the first through hole, fixed groove is had on the left of valve seat, seal ring is had in fixed groove, end cap is had on the left of valve seat, end cap axis there is the second through hole, end cap left end has filtering screen, described valve seat right-hand member is connected with fixing frame, the fixing frame rightmost side has at the bottom of frame, fixing frame sidewall there are some openings, steel ball is had in described fixing frame, steel ball low order end is connected with spring, the spring the other end is connected with at the bottom of frame.
As preferably, described seal ring external diameter equals fixed groove internal diameter, and seal ring thickness is greater than the fixed groove degree of depth.
As preferably, described internal diameter of the seal ring is less than the first through hole internal diameter, and the first through hole internal diameter equals the second through hole internal diameter.
As preferably, described steel ball external diameter is less than the first through hole internal diameter, is greater than internal diameter of the seal ring.
As preferably, described filtering screen covers the second through hole, and filtering screen is hemisphere.
The beneficial effects of the utility model: the utility model by thickness is greater than the fixed groove degree of depth, the external diameter seal ring that is greater than fixed groove internal diameter prevents with in fixed groove, and coordinates end cap, makes there is good sealing between seal ring and valve seat, and fixation; Steel ball external diameter is less than the first through hole internal diameter, is greater than internal diameter of the seal ring, and ensure that steel ball can normal through while the first through hole, when also can ensure that one-way valve in off position, between steel ball and seal ring, energy close contact, reaches good sealing effect; When spring ensure that one-way valve in off position, enough pressure between steel ball and seal ring, is had to make both close contacts; Filtering screen effectively can stop the impurity in refrigeration agent, prevents impurity from destroying sealing.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.

[embodiment]
Consult Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of steel ball type one-way valve of the utility model, comprise valve body 1, valve seat 2, fixing frame 3, end cap 5, import 11 is had on the left of described valve body 1, outlet 12 is had on the right side of valve body 1, described valve seat 2 is in valve body 1, valve seat 2 axis there is the first through hole 21, fixed groove 22 is had on the left of valve seat 2, seal ring 4 is had in fixed groove 22, end cap 5 is had on the left of valve seat 2, end cap 5 axis there is the second through hole 51, end cap 5 left end has filtering screen 52, described valve seat 2 right-hand member is connected with fixing frame 3, fixing frame 3 rightmost side to have at the bottom of frame 31, fixing frame 3 sidewall there are some openings 32, steel ball 6 is had in described fixing frame 3, steel ball 6 low order end is connected with spring 63, spring 63 the other end 31 to be connected with at the bottom of frame, described seal ring 4 external diameter equals fixed groove 22 internal diameter, seal ring 4 thickness is greater than fixed groove 22 degree of depth, described seal ring 4 internal diameter is less than the first through hole 21 internal diameter, first through hole 21 internal diameter equals the second through hole 51 internal diameter, described steel ball 6 external diameter is less than the first through hole 21 internal diameter, be greater than seal ring 4 internal diameter, described filtering screen 52 covers the second through hole 51, filtering screen 52 is in hemisphere.
Utility model works process:
In the course of the work, refrigeration agent enters from import 11 a kind of steel ball type one-way valve of the utility model, and through the filtration of filtering screen 52, push steel ball 6 open, refrigeration agent is flowed out by opening 32, leaves finally by outlet 12.Because seal ring 4 thickness is greater than fixed groove 22 thickness, coordinate end cap 5 by seal ring 4 fixation, to make to produce good sealing between seal ring 4 and valve seat 2 simultaneously; Spring 63 can make there is enough pressure between steel ball 6 and seal ring 4 when one-way valve is in closed condition, reach good sealing; Filtering screen 52 effectively can reduce the impurity in refrigeration agent, and less impurity is 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.
