Abstract
The utility mode relates to a diaphragm pump, comprising a top cover, a sealing sheet, a pressure adjusting spring, a fluid chamber and a support of the fluid chamber. The diaphragm pump is characterized in that a decompression cavity is arranged inside the fluid chamber. A valve element is installed inside the decompression cavity of the fluid chamber. The pressure adjusting spring is sheathed on a pressure adjusting valve. The upper part of the sealing sheet is locked with a top cover which can be adjusted. The convex bar under the top cover and the upper plane of the sealing sheet form an interference fit and axial seal is formed. An adjusting stud is screwed into the middle screw hole on the top cover. The fluid chamber framework is installed inside the injection part on the lower part of the fluid chamber. The inside of the fluid chamber support is additionally provided with a frame steel. The fluid chamber and the fluid chamber support are fixedly connected with each other by eight bolts. The diaphragm pump has the beneficial effects that the intensity of the fluid chamber is improved, fluid chamber has double sealing functions, and water leakage can be avoided caused by the deformation of the fluid chamber. The compression amount of the pressure adjusting spring can be changed by rotating the adjusting stud, and the uniform working pressure of the whole bulk diaphragm pump can be ensured.
Description
Technical field
The utility model relates to a kind of diaphragm pump.
Background technique
The fluid chamber of more existing diaphragm pumps is owing to adopt the material of PA66+40%GF, and easily the moisture absorption makes the materials and parts deliquescing under the environment that is subjected to the water logging bubble, and product is prone to distortion and to cause product to leak bad when being subjected to high pressure work; Because product is axially stressed bigger in assembling, to making the wherein subordinate's distortion of collapsing behind certain hour of fluid chamber's support, therefore pump head inner sealing deficiency produces internal leakage and causes the flow of diaphragm pump and the situation of working pressure decline; The most fluid chamber of common in the market diaphragm pump are when the fluid chamber support is connected, screw is with six, and the span between the screw is bigger relatively, and fluid chamber's materials are Reinforced Nylon, the water absorption rate of its raw material own is higher, is prone to distortion and causes seal failure under the situation of being stressed.In addition,, can produce bigger discreteness between pump in the use and the pump, be unfavorable for the conformity of quality of product because error, spring performance, the heat treated difference of work in-process can cause the initial pressure of spring and working pressure all inconsistent.
The model utility content
The purpose of this utility model provides a kind of diaphragm pump, with overcome existing product being prone to the distortion and cause product leak bad, sealing effect is bad, service behaviour is relatively poor, parts connect unstable deficiency.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of diaphragm pump, comprise top cover, diaphragm seal, pressure adjusting spring, fluid chamber and fluid chamber's support, described fluid chamber inside is provided with pressure-releasing cavity, valve block is packed in the pressure-releasing cavity of fluid chamber, pressure regulator valve is buckled on the pressure regulation valve block, described pressure adjusting spring is placed on the pressure regulator valve and fixing installing spring supporting base, diaphragm seal is stamped on the top of supporting base, described diaphragm seal is packed on the heavy stand of pressure-releasing cavity of fluid chamber, the top of diaphragm seal fastens displaceable roof, and the last plane of convex tendon under the described top cover and diaphragm seal produces interference fit and forms axial seal; Accompany the carry-over moment piece between described top cover and the diaphragm seal, lock screw is screwed in the top cover, and described adjusting double-screw bolt screws in the middle screw of top cover.Add fluid chamber's skeleton in the moulding of described fluid chamber bottom, described fluid chamber internal stent is added with the skeleton steel, and described fluid chamber is connected with fluid chamber eight screw of support employing.
The beneficial effect of diaphragm pump described in the utility model is: improved the intensity of fluid chamber, had the function of double seal, avoided leaking because of fluid chamber's distortion causes; Avoided product distortion to occur, can guarantee can not produce internal leakage and situation that the flow that causes and pressure descend in assembling and after operation a period of time; Regulate the decrement that double-screw bolt changes pressure adjusting spring by rotation, can eliminate the pressure gap between the spring, can be made into the pump that different operating pressure requires, can guarantee diaphragm pump working pressure unanimity by the gross with identical spring.
