Abstract
The utility model belongs to a valve, in particular to a diaphragm valve in a manual operating or a pneumatic operating type, composed of a valve body, a valve hood, a valve core, etc. Through the adoption of the technical measures that a diaphragm is arranged in the valve hood and the valve hood is provided with a compressed air inlet, etc., the defects that the existing valve is easy to leak, etc. are overcome; the utility model has good tightness; the utility model has the advantages that two-step control can be achieved through the pneumatic power, the material flow quantity can be arbitrarily controlled through the opening degrees of the manual prearranged valve, or the opening degrees of the valve can only be manually regulated as required, and can be widely used for the fields, such as pharmacy, temperature control, material conveyance, etc.
Description
The utility model belongs to valve, be meant especially a kind of both can be manual, again can be pneumatically-operated manually, pneumatic diaphragm valve.
Present existing valve all has valve rod or axle with spool and external communications, between valve rod or axle and the valve body (valve gap) mechanical relative movement is arranged, be difficult to seal fully, easily produce seepage, and general membrane valve or be pneumatic or for electronic when power failure or when stopping the supple of gas or steam, exists the shortcoming that can't operate, its working state also has only standard-sized sheet or full cut-off two states, and state can not mediate.
The purpose of this utility model is the keying of finishing valve by manual or pneumatic operation is provided, and sealing effect preferably manually, pneumatic diaphragm valve to be to overcome the deficiency of prior art.
Overall structure of the present utility model is:
A kind of manual, pneumatic diaphragm valve comprises valve body (1), valve gap (14), spool (8), diaphragm (3), valve rod (9) handwheel members such as (6), and valve rod (9) connects with valve gap (14), and valve rod (9) two ends are equipped with spool (8) and handwheel (6); It is characterized in that valve gap (14) one ends and valve body (1) sidewall secure fit, valve body (1) sidewall is offered the inlet (11) and the outlet (13) of material, the inlet (11) of valve gap (14) and material, between the outlet (13) diaphragm (3) is set, valve gap (14) sidewall offers compressed air inlet (4).
Other structure characteristics of the present utility model are:
End cap (10) is packaged in valve gap (14) opposite side, is filled with filler (5) between valve gap (14) and the valve rod (9).
Be provided with O-ring seal (2) between diaphragm (3) and valve body (1) sidewall.
Accompanying drawing of the present utility model has:
Fig. 1 is a structural representation of the present utility model
Accompanying drawing has provided embodiment of the present utility model, in conjunction with the accompanying drawings embodiment of the present utility model is described as follows:
The overall structure of present embodiment as shown in Figure 1, the wherein convex edge inner thread assembling of valve gap (14) bottom and valve body (1) sidewall, spool (8) is slidingly matched with valve rod (9) end, handwheel (6) connects with valve rod (9) the other end drive fit, valve gap (14) madial wall and diaphragm (3) and the cavity that is surrounded are air chamber (7), between valve body (1) sidewall and the diaphragm (3) O-ring seal (2) is set, rely on the catch (12) that is arranged at valve body (1) inwall that the two is spaced apart between inlet of material (11) and the outlet (13), all the other structures as described above.
Working principle of the present utility model is as follows: the compressed air inlet offered (4) of source of compressed air with valve gap (14) sidewall is communicated with, when material flows to material inlet (11) by direction shown in the arrow among Fig. 1, press spool (8) by controlling compressed-air actuated pressure or rotating handwheel (6), can make diaphragm (3) produce the inlet (11) of deformation shutoff material or outlet (13) thus reach the purpose of the flow of control material.
The obtained technological progress of the utility model is not have to becoming owing to diaphragm is only flexible Sliding phenomenon, so can guarantee the sealing property that this diaphragm valve is good, this diaphragm valve removes can be real Now outside the standard-sized sheet or two controls of full cut-off to valve, also can be by the predetermined diaphragm of hand wheel Opening degree at random to control the turnover flow of material, can be widely used in pharmacy, temperature control Reach the fields such as mass transport.
Claims (3)
1, a kind of manual, pneumatic diaphragm valve comprises valve body (1), valve gap (14), spool (8), diaphragm (3), valve rod (9), handwheel members such as (6), and valve rod (9) connects with valve gap (14), and valve rod (9) two ends are equipped with spool (8) and handwheel (6); It is characterized in that valve gap (14) one ends and valve body (1) sidewall secure fit, valve body (1) sidewall is offered the inlet (11) and the outlet (13) of material, between the inlet (11) of valve gap (14) and material, the outlet (13) diaphragm (3) is set, valve gap (14) sidewall offers compressed air inlet (4).
2, manual, pneumatic diaphragm valve according to claim 1 is characterized in that end cap (10) is packaged in valve gap (14) opposite side, is filled with filler (5) between valve gap (14) and the valve rod (9).
3, manual, pneumatic diaphragm valve according to claim 1 is characterized in that being provided with O-ring seal (2) between diaphragm (3) and valve body (1) sidewall.
