Abstract
The utility model discloses a manual diaphragm valve, comprising a valve cap, a valve rod and a valve body. An upper limit and a lower limit are designed on the valve cap. A valve clack and a membranein the valve cap pass through the valve rod to match and connect a top cap at the upper part of a hand wheel through a screw. The utility model has the advantages of no blind angle, no detention andavoidance of beyond opening and beyond closing in an operation.
Description
Technical field
The utility model relates to a kind of valve, specifically a kind of manual diaphragm valve.
Background technique
The membrane valve valve body material of prior art adopts the common stainless steel casting to form, original valve body rectangular shape design, dead angle and delay are arranged, shortcomings such as trachoma and deoxidation point can appear, in use the delay of object can appear in trachoma, and long-time detained matter can go bad, and the deoxidation point can be corroded when flowing through the medium band pH value of valve, bring inconvenience to use, also do not reached the requirement of health level.
Original valve body rectangular shape design has dead angle and delay.
The situation of position and Guan Guowei appearred out in valve gap in operating process, the situation that diaphragm excessively damages because of switch, and bad adjusting simultaneously, use occasion is not extensive yet; Also can't observe directly the keying state of valve.
The model utility content
(1) technical problem that will solve
Technical problem to be solved of the present utility model is the defective at prior art, and manual diaphragm valve is provided, and valve body does not have trachoma, no deoxidation point, no dead angle and zero is detained, and upper limit and lower caging device are arranged, and has avoided occurring out in operating process the situation of position and Guan Guowei.
(2) technological scheme
The technological scheme that its technical problem that solves the utility model adopts is: manual diaphragm valve, and its structure comprises valve gap, valve rod, valve body; Designed upper limit and lower limit on the described valve gap, the top cap that the flap of described valve gap inside and diaphragm pass valve rod and handwheel top by screw matches and is connected.
Described valve inner adopts the design of slope current linear structure, has added chromosphere at the neck of valve gap.
Described valve body material adopts the high-accuracy cast of stainless steel to form.
(3) beneficial effect
Manual diaphragm valve of the present utility model is compared with prior art, has following beneficial effect:
In conjunction with the valve body shortcoming of old type, existing valve body adopts the high-accuracy cast of stainless steel to form, and outside the shortcoming of removing old type, its advantage also has the density height, has higher corrosion resistance.
In the design of valve body, with the design of original rectangular shape, change present gradient type design into, thereby embody more no dead angle and zero delay advantage.
Opening and closing situation according to valve, upper limit and lower limit on valve gap, have been designed, avoided in operating process, occurring out the situation of position and Guan Guowei, the situation of having avoided diaphragm excessively to damage because of switch, can also regulate the closed position of different materials diaphragm with the adjusting screw of handwheel upper end, thereby adapt to the use occasion of valve; Having added chromosphere at the neck of valve gap can be with the keying state of directly observing valve.
Description of drawings
Figure is the structural representation of manual diaphragm valve of the present utility model.
Among the figure: 1. valve body; 2. block a shot; 3. valve gap; 4. switch indication; 5. handwheel; 6. top cap; 7. valve rod; 8. flap; 9. screw; 10. diaphragm.
Embodiment
Next explain below with reference to Figure of description manual diaphragm valve of the present utility model being done.
Manual diaphragm valve of the present utility model, its structure comprise valve gap 3, valve rod 7, valve body 1; Designed upper limit and lower limit on the described valve gap, the top cap 6 that the flap 8 of described valve gap inside and diaphragm 10 pass valve rod and handwheel 5 tops by screw 9 matches and is connected.
Described valve inner adopts the design of slope current linear structure, with original rectangular shape design, changes present gradient type design into, thus embody more no dead angle and zero delay advantage.Neck at valve gap has added chromosphere.Directly observe the keying state of valve.
Described valve body material adopts the common stainless steel casting to form.Existing valve body adopts the manufacturing of stainless steel special precision technology to form, and outside the shortcoming of removing old type, its advantage also has the density height, has higher corrosion resistance.
The above embodiment is a kind of of the more preferably concrete mode of execution of the utility model, and common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection domain of the present utility model.
Claims (3)
1, manual diaphragm valve, its structure comprises valve gap, valve rod, valve body; It is characterized in that: designed upper limit and lower limit on the described valve gap, the top cap that the flap of described valve gap inside and diaphragm pass valve rod and handwheel top by screw matches and is connected.
2, manual diaphragm valve according to claim 1 is characterized in that: described valve inner adopts the design of slope current linear structure, has added chromosphere at the neck of valve gap.
